Carolyn Deller & Tatiana Sandino* Harvard Business School November 24, 2015 Abstract Using data from a retail chain, this paper studies the effects of a preferential plan providing incentives only to exemplary employees. Such plans incorporate elements of tournaments (through the selection of employees chosen largely on the basis of past performance but incorporating some managerial discretion) and linear incentives to align employees with company goals and values. We find that, on average, the implementation of the preferential incentive plan was associated with improvements in sales. Also, we find that this plan was associated with greater improvements in sales and gross profits, and reductions in the incidence of bad audits in stores where employees were initially less likely to be aligned with company goals. However, the plan was associated with lower sales and gross profits, and higher incidence of bad audits, absenteeism, and turnover in some situations where employees could have perceived the plan to be unattainable or unfair. Our study sheds light on the impact of preferential incentive plans, and the conditions under which these plans are more or less effective. * Corresponding author’s contact information: Morgan Hall 367, Harvard Business School, Boston MA 02163 Phone: 617.495.0625 e-mail: tsandino@hbs.edu Keywords: Preferential incentive plans; exemplary employees; incomplete contracts; company values; tournaments; subjectivity; equity theory; perceived unfairness; social identity; retail chains.

Introduction Many organizations rely on incentive plans to motivate high performance. Most incentive contracts, however, are incomplete and reward only some of the relevant tasks that employees should pursue to achieve company goals. Incomplete contracts often trigger counterproductive behaviors that may hurt company objectives, as the employees may focus exclusively on the tasks that are rewarded at the expense of other relevant tasks (Baker, Gibbons, and Murphy [1994], Prendergast [1999], Gibbs, Merchant, Van der Stede and Vargus [2004, 2009]). One way companies implement incentive contracts while discouraging counterproductive behaviors associated with incomplete contracts is by introducing subjective assessments of performance into the incentive package (Baker et al. [1994], Murphy and Oyer [2001], Gibbs et al. [2004, 2009]; Rajan and Reichelstein [2006]). Incentives typically comprising a subjective element include salary raises, discretionary bonuses, and promotions (Baker, Jensen and Murphy [1988], Prendergast [1999], Campbell [2008], Grabner and Moers [2013]). The use of managerial subjectivity enables circumstances that may have not been foreseen and/or are not captured in an objective quantitative measure (e.g., gaming of an incentive plan, reduced quality, adherence to core values) to be incorporated into performance assessments. However, subjective assessments can give rise to supervisor biases, lead workers or teams to engage in unproductive activities in order to influence these assessments, and/or demotivate workers or teams who attribute an adverse subjective judgment to inequities in the firm (Prendergast [1999], Murphy and Oyer [2001], Ittner, Larcker, Meyer [2003], Gibbs et al. [2004], Bol 2011, Du, Tang and Young [2012]). Additionally, not all firms can offer opportunities for promotions to their best employees due to lack of growth, limitations related to the employees’ geographic location, and 1 different skill requirements in higher level positions (Baker et al. [1988], Lazear [2004], Grabner and Moers [2013]). This study considers the use of a type of incentive plan, specifically a “preferential incentive plan,” that incorporates managerial discretion to a limited degree, in order to reap the benefits of both incentive contracts based on objective measures of performance and incentives based on subjective assessments, while mitigating some of the difficulties associated with each of them. Specifically, we define a “preferential incentive plan” as an incentive contract with a tournament component and an incentive pay component. In the tournament component: (1) objective performance metrics are applied to identify a limited number of employees or teams that are considered to have the greatest performance (herein, “top-performing” employees or teams) within a larger group; (2) managers then determine whether each top-performing employee or team deserves to receive incentives under the preferential plan, affording managers limited discretion to verify the top performing employees’/teams’ alignment with the spirit of the plan and the core values of the firm (top employees or teams deemed deserving of receiving incentives are herein referred to as a “selected” employees or teams). In the incentive pay component, the selected employees or teams then become eligible for incentives under the preferential plan (herein, “bonuses”) that are awarded based on objective performance metrics. Preferential incentives may take different forms: for example, they might include incentive plans created specifically for selected, exemplary employees (e.g., in the form of bonuses or employee stock options), or opportunities for increased earnings from incentive plans already available to all employees (e.g., increases in bonus rates or commissions). A key distinction between preferential incentive plans and standard non-linear incentive plans including a threshold is that preferential incentive plans incorporate manager discretion to periodically 2 determine whether top-performing employees deserve to become eligible or not for incentives, while non-linear plans do not incorporate any discretion to determine which employees are eligible or not, automatically leading to incentive payouts any time the threshold is achieved. While the use of preferential incentives is not as widespread as the use of incentive plans including all employees (with or without a threshold), we have learned of multiple organizations that identify and reward “deserving” top-employees with additional incentives (more commonly through employee stock options or stock ownership plans). The purpose of this study is two-fold. First, we examine the net effects of a preferential incentive plan on productive and counterproductive outcomes at a retail chain. Second, we examine whether implementing preferential incentives is associated with more favorable outcomes for employees less likely to be aligned with company goals and values (e.g., because they are located in remote locations in an organization where core values are transmitted through face-to-face interactions) and less favorable outcomes for employees more likely to perceive the plan as inequitable. Testing whether motivating employees to perform according to company goals and values can offset potential inequity costs is relevant to practitioners considering whether to use these plans to drive high levels of desirable performance. Moreover, it is important to understand how different factors (such as geographic location, the provision of resources, and social identity) can affect the tradeoffs that may determine the overall effects of preferential incentive plans on outcomes. Our analyses use data from a mobile phone retailer (hereafter MPR) operating in Delhi, India. This retail chain differentiated itself in the market by providing trustworthy, high quality service. MPR provided us with a suitable setting to examine our research question since it introduced a preferential incentive plan among its company-owned stores in February of 2013, in 3 which stores competed against each other to become selected and earn the right to receive incentives on a daily basis. The company introduced this preferential incentive plan to motivate store teams in high performing stores that were selling in an “honest and consistent way” to exert effort towards the achievement of daily targets. We use two years of data (from February 2012 to January 2014) from 35 stores and 731 store-months (the preferential incentive plan was first introduced in February 2013), to examine the effects of the plan on productive outcomes (i.e., the stores’ sales and gross profits) and counterproductive outcomes (i.e., “percentage of bad audits,” defined as the percentage of times when an audit uncovered any items missing from the store or cash shortages, unauthorized absenteeism, and employee turnover). We also use data (from February 2012 to January 2014) from 60 franchise stores (1440 franchise store-months) operating in the same areas as companyowned stores, to control for market conditions. We complemented our empirical analysis with interviews with the managing director as well as 11 store managers (5 from selected stores and 6 from not-selected stores) to validate the results of our analyses. A difference-in-differences analysis comparing the performance of company-owned stores with that of the franchise stores reveals a positive net effect of the preferential incentive plan. The introduction of the preferential incentive plan resulted in a boost in sales for companyowned stores (regardless of whether the stores were “selected” or not during the sample period) relative to franchise stores. In line with this finding, our follow up interviews suggested a general pattern whereby store managers from both selected and not-selected stores were highly motivated to increase their teams’ efforts following the implementation of the plan. Focusing on the subsample of company-owned stores (i.e., those stores where the preferential incentive plan was implemented), we explore the tradeoffs implicit in the plan. We begin by 4 examining whether the preferential incentive plan was more beneficial when the distance between the store and the head office was greater, since, according to the company’s managing director, employees in more remote stores were generally less engaged and less exposed to the company’s values. Van den Steen [2010a] provides theoretical support for this argument, presenting an analytical model that indicates that there will be greater homogeneity in shared values amongst the employees that make the decisions that have the greatest impact on the firm’s success; in our setting, these employees were generally located at headquarters and more likely to interact with store managers of nearby stores. We find that, following the introduction of the preferential incentive plan, a negative effect of distance from headquarters on both sales and gross profit was offset. Additionally, a higher incidence of bad audits and store manager turnover in stores further from headquarters was more than fully offset after the introduction of the preferential incentive plan. The effect that the preferential incentive plan would have on not-selected stores was less clear than the effect it would have on selected stores, since store teams in not-selected stores were more likely to perceive the plan as “out of reach” and/or “unfair.” Among not-selected stores, we expected the preferential incentive plan to be least effective in stores receiving fewer resources to do their work and “compete” for the right to be selected to become bonus-eligible and in stores where teams had the potential to feel discriminated against since the store managers’ social identity (defined by religion and/or state of origin; two of the most salient demographic variables in India) 1 was underrepresented in the group of store managers of selected stores. Consistent with expectations, we found some evidence that the implementation of the preferential incentive plan in a not-selected store receiving fewer resources to operate 1 Gender was not highlighted as a relevant characteristic in this context, since all the store managers (except for one who was present in the store for less than 3 months) were men. 5 (inventory availability, number of store team members, supervisor ranking, and attractiveness of the store location) was associated with a decrease in sales and gross profits, and an increase in absenteeism and store manager turnover relative to not-selected stores with greater resources. We also found some evidence that the effects of the preferential incentive plan were less favorable (i.e., led to lower sales and gross profits, as well as an increase in bad audits) in not-selected stores where either the religion or the state of origin of the store manager was underrepresented among the group of store managers of selected stores. Our study contributes to the literature in two ways. First, it is well known that incomplete contracts can lead employees to behave myopically, focusing exclusively on the aspects of the job rewarded by their contracts at the expense of other duties that are relevant to the achievement of company values and goals (Baker et al. [1988], Prendergast [1999], Gibbs et al. [2004]). Prior studies suggest that, in such settings, managers can motivate employees to pursue broader organizational goals by favoring employees that managers subjectively assess as being better aligned with company goals, and that are therefore trusted to do “the right thing” (Van Den Steen [2010a, 2010b], Abernethy, Dekker and Schulz [2015]). Our study tests this idea through a mechanism, preferential incentives, that enables managers to favor high performing employees achieving their goals “the right way,” and explores the extent to which this mechanism can mitigate dysfunctional behaviors unintendedly caused by incomplete contracts. Preferential incentive plans incorporate elements of implicit incentives (such as those incentives that emerge when a company evaluates all aspects of an individuals’ job to determine promotions) and explicit incentive contracts, which can complement each other in incomplete contract settings (Gibbons and Murphy [1992]). 6 While preferential incentive plans can contribute to aligning employees’ incentives to the pursuit of organizational goals, they can also demotivate employees who may perceive the plans as inequitable or unattainable. Our study contributes to the tournament, social identity, and equity literatures by highlighting the role that equity concerns may play in the effectiveness of preferential incentives. Overall, our study shows that the net effect of a preferential incentive plan can be positive. Yet our results caution practitioners that preferential incentives may lead to unintended behaviors in settings where inequity and discrimination concerns are more likely to emerge. The plan might be most effectively implemented in firms where resources can be distributed evenly and the skills of different social identity groups are comparable. Our study proceeds as follows. Section 2 presents our hypothesis development. Section 3 describes the company and the preferential incentive plan analyzed in this study. Section 4 presents our research design and main empirical analyses. Our first set of analyses compare the effect of the preferential incentive plan on sales in company-owned stores relative to our control group of franchise stores where the plan was not introduced. Our second set of analyses focus exclusively on company-owned stores, examining different store circumstances affecting the impact of the preferential incentive plan on productive and counterproductive outcomes. Section 5 concludes. 2. Hypotheses Development 2.1 Effect of Preferential Incentives on Outcomes The initial process by which potential “selected employees/teams” in a preferential incentive plan are identified (we use the word “potential” since the final group of “selected employees/teams” is subject to managerial discretion) resembles the process used to identify 7 “winners” in tournaments (Lazear and Rosen [1981], Casas-Arce and Martínez-Jerez [2009]). And in the same way in which tournaments should provide incentives to perform to “winners” and “losers,” preferential incentive plans should motivate both selected and not-selected employees/teams to work hard and in accordance with the spirit of the plan. Selected employees/teams should be motivated not only by the additional incentive payouts they can obtain, but also by the recognition associated with being “selected” for the additional incentive. Not-selected employees/teams should be motivated to work hard in a way consistent with company objectives and values in order to be recognized and become eligible for increased incentives. Although preferential incentives resemble tournaments, they are different in two important respects. First, the rewards associated with these plans are not fixed but, instead, consist of additional incentives that are “turned on” once a participant is “selected.” This feature makes preferential incentives potentially more effective at driving improved performance than tournament incentive plans beyond the point of eligibility, since preferential incentive plans provide selected employees with incentives to continue improving their performance beyond the point of selection. 2 Prior tournament literature shows that employees with a strong lead become complacent overtime in situations where the rewards associated with winning the tournament are fixed (Casas-Arce and Martínez-Jerez [2009]). Second, unlike many of the tournament incentive plans empirically studied in the literature (Ehrenberg and Bognanno [1990], Becker and Huselid [1992], Casas-Arce and Martinez-Jerez [2009]), the selection criteria used in preferential incentive plans is not entirely objective or 2 Providing “incentives” as a reward could also lead to these plans being less effective than traditional tournaments with fixed rewards, since under these plans employees need to meet two hurdles to receive a payout. 8 determined by formula. Preferential incentive plans not only require employees to outperform their peers on objective dimensions, but also require them to follow the spirit of the plan and act in accordance with company values. This feature makes preferential incentive plans particularly desirable in circumstances where a subset of important employee actions or job outcomes cannot be easily observed or measured, and/or where adherence to company values should be strengthened (for instance, to ensure consistency across a retail chain). At the same time, the managerial discretion used in preferential incentive plans could lead not-selected employees to question the legitimacy of the selection process. According to equity theory, individuals will become demotivated if they perceive that the outcomes (in this case the rewards) they receive for their job inputs (in this case their ability and effort) are not comparable to the outcomes their peers receive for their inputs. These inequity perceptions can lead workers to shirk at their jobs and engage in counterproductive behaviors (e.g., Adams [1963], Capelli and Chauvin [1991], Fehr and Gachter [2000]). Our discussion above suggests that preferential incentive plans are likely to provide strong incentives to employees, but could potentially demotivate some or all “not-selected” employees. Hence the overall effect of a preferential incentive plan on performance and counterproductive outcomes is an empirical question. However, since a company implementing a preferential incentive plan would do so only if it expected positive results, we state our first hypothesis as follows: Hypothesis 1 (H1): The introduction of a preferential incentive plan in an organization will have a positive effect on employee/business unit outcomes. 9 2.2 Factors Affecting the Effectiveness of Preferential Incentives The potential benefits and costs associated with the introduction of a preferential incentive plan are likely to vary based on employee/business unit characteristics. In particular, the introduction of a preferential incentive plan might be most beneficial where there is an opportunity to improve the alignment of employees with company goals. These situations may arise when the employees’ circumstances are such that their personal incentives are less aligned with those of the company. In the context of our study, interviews revealed that employees tended to be less aligned with company objectives if they operated in remote locations than if they operated in close proximity to the head office. This makes sense since “more important employees” (i.e., employees that make the decisions that have the greatest impact on the firm’s success) will have greater homogeneity in their beliefs (Van den Steen, [2010a]) and thus are best placed to exemplify the organization’s objectives and values. Since these employees are located in the head office there is less opportunity for face-to-face interactions between these employees and employees in remote locations. We predict more favorable effects from preferential incentives in circumstances requiring greater alignment. Formally, Hypothesis 2 (H2): The introduction of a preferential incentive plan will be associated with greater improvements in employee/business unit outcomes in situations where the employees/teams are located further from the head office. Despite its advantages, the introduction of a preferential incentive plan could be inconsequential or even cause demotivation if employees view the plan’s eligibility targets as unattainable or inequitable. Arguments from tournament theory suggest that biased contests will result in lower effort (see for example Prendergast [1999]). Furthermore, equity theory suggests 10 that employees who believe they are underpaid relative to comparable peers (i.e., peers who are similarly skilled and who exert similar effort to them), will not only decrease effort but might also engage in counterproductive behaviors (Adams [1965]). Prior research has documented a range of counterproductive behaviors resulting from inequity perceptions such as absenteeism and theft (Adams [1965], Greenberg [1990], Capelli and Chauvin [1991], Fehr and Gachter [2000], Chen and Sandino [2012]). According to equity theory, the introduction of a preferential incentive plan by itself would not lead to inequity perceptions if employees believed the compensation they received for the effort and skill they invested in their job was commensurate with that received by their peers. However, differences in pay resulting from a preferential incentive plan (particularly those resulting from not being selected for the incentive) could cause negative feelings among employees if they attribute some of those differences to being placed at a disadvantage relative to their peers (Larkin, Pierce and Gino [2012]). In fact, Matsumura and Shin [2006] show that relative incentive plans are less effective when employees consider their local circumstances disadvantageous. Prior research also suggests that an individual’s response to a tournament-like incentive plan depends on how fairly s/he perceives her/his social identity group is treated (Schotter and Weigelt [1992]). 3 Individuals belonging to what they perceive to be disadvantaged groups (e.g. minority groups, potentially subject to discrimination) are more likely to “drop out” and supply no effort in a tournament unless equal opportunity policies are put in place (Schotter and Weigelt [1992]). We conjecture that not-selected employees/business units will be more likely to perceive the preferential incentive plan as inequitable if (a) they receive fewer resources from the company to do their jobs, possibly inhibiting their capacity to effectively “compete” for the right to 3 Social identity is defined as “that part of an individual’s self-concept which derives from their knowledge of their membership of a social group (or groups) together with the value and emotional significance attached to that membership” (Tajfel [2010], p.2). 11 participate in the preferential incentive plan, and/or if (b) they perceive there is some bias against them, which may arise from their social identities being disproportionately underrepresented among the selected employees/business units. Accordingly, our third set of hypotheses states: Hypothesis 3a (H3a): Among the subset of employees/business units not-selected for a preferential incentive plan, the introduction of the plan will be associated with a deterioration of (an improvement in) outcomes, the fewer (the greater) the resources received by the employees/business units to do their jobs. Hypothesis 3b (H3b): Among the subset of employees/business units not-selected for a preferential incentive plan, the introduction of the plan will be associated with a deterioration of outcomes in situations where members of the employees’ (or business unit managers’) social identity group are disproportionately underrepresented among the selected employees (or managers of the selected business units). 3. Research Setting We test our hypotheses using two years of monthly data from a mobile phone retail chain (MPR) operating in Delhi, India that introduced a preferential incentive plan in its 35 companyowned stores. When the company implemented this preferential incentive plan in February of 2013, it already provided traditional sales commissions to its store managers and cashiers on a monthly basis, primarily based on the number of items sold. While the traditional plan had yielded acceptable results, the managing director of the retail chain decided to introduce additional incentives, in the form of a preferential incentive plan (comprising a daily bonus scheme for “selected” stores) to motivate store teams (all team members in selected stores would 12 receive an incentive payout) in high performing stores that were selling in an “honest and consistent way” to exert effort towards the achievement of daily targets. Our sample comprises 731 store-months of data from the 35 company-owned stores where the preferential plan was introduced. We complemented our quantitative analysis with insights from interviews to the managing director of the company as well as to 11 managers of company-owned stores (5 from selected and 6 from not-selected stores), where we asked open ended questions about their general reactions to being selected (or not-selected) for the purposes of the preferential incentive plan. 4 Most of our analyses focus on analyzing differences in the effect that the preferential incentive plan had across different company-owned stores. We also assess the overall sales effect of the preferential incentive plan in our company-owned stores (our “treatment sample”) vis-àvis a control sample comprised of 1,440 store-months of data from 60 franchised stores where the preferential incentive plan was not introduced, operating in the same areas as the companyowned stores. Figure 1 provides a timeline and description of the sample. We dropped observations corresponding to the months of November 2012 and 2013 (when holiday incentives substituted other forms of incentives, including the preferential incentives in company-owned stores) and observations corresponding to the months of February 2013 – June 2013 for 21 stores where the introduction of the preferential incentive plan was delayed while the company was running a pilot study of the plan. 5 Our final sample comprised data from 583 company-owned 4 The store managers were interviewed in September of 2015 (more than a year after the sample period analyzed ended). At that time, the preferential incentive plan had recently been discontinued. Prior to the discontinuation, the plan had been slightly modified: the incentives provided to “selected” stores were applied only to weekends and, we learned from the interviews that, in at least one instance, the winning stores were recognized in a social event. Generally speaking, we believe that the changes to the plan relative to the plan during our sample period did not affect the responses that the store managers provided. When we thought the answers could have been affected by changes (e.g., due to the social event) we asked for clarification. During our presentation of the results of this study to the company, the managing director expressed interest in reinstating the preferential incentive plan. 5 All of our results are robust to excluding the matching months for those stores in 2012. 13 store months and 1,320 franchised store months. The company-owned stores sold a full range of mobile phone products, including handsets; accessories; prepaid and post-paid minutes; and connections (i.e. activation of mobile phone numbers); while most franchised stores focused on selling connections, prepaid and post-paid minutes. Franchised stores were mom-and-pop stores that partnered with the company to take advantage of the company’s scale. In return for franchise fees, the company completed the activation process for new connections sold by the franchisees; collected payments from, and negotiated with, suppliers on behalf of the franchisees; provided franchisee owners with brand recognition; and kept franchisees informed about the latest news and promotions offered in the mobile market. Although the products sold by the franchised stores were typically more limited than those sold by company-owned stores, 6 the franchised stores were a good candidate for a control sample given that, as the managing director confirmed, the franchisees’ sales reflected the same market demand, shocks and trends as the company-owned stores. In other words, the data fitted the common trends assumption, which is the key assumption to conducting difference-in-differences analyses (Angrist and Pischke [2009], p. 230). MPR had traditionally paid monthly bonuses to the store employees of its company-owned stores, but decided to introduce a preferential incentive plan on top of the monthly bonuses in February of 2013. This plan would be implemented to further reward and motivate its exemplary store teams by enabling them to participate in a daily bonus scheme. Store teams typically consisted of two store employees (a store manager and a cashier) plus one or more promoters provided by the various brands whose products/services were sold in the store. While the 6 Several franchised stores sold mobile phones in addition to prepaid and postpaid minutes as well as other products unrelated to the mobile phone industry. The data that we have access to includes only revenue data from connections, prepaid and post-paid minutes. 14 traditional monthly bonuses were awarded only to the store manager and the cashier, the daily bonus payments of the preferential plan would be awarded to all members of the store team. Only the top tercile performing company-owned stores would be selected to participate in the daily bonus scheme. 7 Selected stores needed to demonstrate superior sales performance relative to other stores, deliver a consistently high level of sales (occasionally reaching at least 100,000 INR/day, roughly US$1,670/day) for at least two to three consecutive months, and have a good track record of honest behavior and consistent execution on a daily basis. Decisions regarding which stores were selected and which were not selected were made regularly (roughly, on a monthly basis), based on the stores’ prior three months performance. The right to participate in the daily bonus scheme could be taken away from a selected store at any given point in time if its performance declined relative to that of other top-tercile performing stores or if the store employees were caught cheating or engaging in counterproductive behaviors (e.g., selling only on the few days when they would be most likely to receive the daily bonus). The preferential incentive plan paid each person in a selected store about 150 INR (US$3) every time the store reached the minimum daily sales target, plus 50 INR (US$0.83) for every additional 50,000 INR the store team sold beyond the minimum daily sales target. Once a store was selected to participate in the daily bonus scheme, the minimum daily sales target was determined for the store based on local market demand. The payoffs from the daily bonus scheme were significant for store employees whose fixed salaries were typically lower than 150 INR per day and whose total compensation (including commissions) was about 500 INR (US$8.5) per day in a non-holiday month. Under the plan, store teams also earned recognition in 7 The managing director explained that they had decided to constrain the preferential plan to one third of the stores because they wanted to recognize top performers; they had budget constraints; and they did not want to reward stores that were not selling in a consistent way to avoid having stores gaming the system by recording sales from multiple days on one day. 15 the form of a congratulatory email sent to everyone in the company each time a store earned an award. This was an attractive setting to test the effects of a preferential incentive plan, for various reasons. First, we were able to obtain one year of monthly data, capturing key measures of the productive outcomes the plan intended to promote (sales and gross profits) and the counterproductive outcomes the plan intended to discourage (“bad audits,” absenteeism, and turnover), before and after the introduction of the plan. Second, the stores’ performance and details of the plan were clear to all store managers. In particular, the managing director of the company was in constant communication with the store staff through email, announcements appearing in the company’s extensive database system, and weekly meetings with store managers. Furthermore, each of the store managers had continuous access to their store’s performance as well as all other stores’ performance through the database system. 8 These communication mechanisms, implemented before our sample period, enabled employees to learn about the preferential incentive plan once it was introduced. After the incentive was put in place, the managing director reminded the store managers of the selection criteria used to decide which stores would be selected to participate in the daily bonus scheme and which would not, during their recurring weekly meetings. Third, there existed enough variation among store characteristics that could affect the stores’ reactions to the introduction of the preferential incentive plan, allowing us to test our second and third hypotheses. Before examining the reaction that selected and not-selected company-owned stores had to the introduction of the preferential incentive plan, we examined whether the initial set of selected stores in fact corresponded to the top-tercile performing stores in the company. As illustrated in 8 The weekly meetings were not mandatory. Store managers operating stores that were far from headquarters did not frequent these meetings and instead learned about incentive schemes through the database system and via email. 16 Table 1, a comparison of the performance of selected and not-selected stores reveals that the selected stores, with average monthly sales equal to 1,861,715 INR (~US$ 31,030) and monthly gross profits of 100,800 INR (~US$ 1,680) over the year prior to the implementation of the plan, significantly outperformed the not-selected stores, with average monthly sales equal to 441,671 INR (~US$ 7,360) and monthly gross profits of 22,749 INR (~US$ 380) in the year prior to the introduction of the preferential incentive plan. Furthermore, a ranking of the stores based on their average monthly sales over the year prior to the implementation of the preferential incentive plan in February 2013 reveals that all but one of the stores selected within the first six months of the plan being introduced were ranked top-tercile in terms of sales, and all but two were ranked toptercile in terms of gross profits. One store that was not ranked among the top third in either sales or profits before February 2013 became selected in July 2013 after a store manager from a highly successful selected store was moved to that unselected store and tripled its sales within one month (placing the store among the top tercile performers). The second store that was not ranked among the top-tercile in terms of gross profit was among the top tercile performers in terms of sales and was just below the top tercile performers in terms of gross profits. According to the managing director, differences in sales and gross profit performance were predominantly driven by the store managers’ execution. She assured us, nevertheless, that she considered the store’s potential (based on peak sales achieved in the past) in deciding which stores fell and which did not fall among the top-tercile performers. 9 These results suggest that selection was clearly based on performance. Our tests comparing other store characteristics of selected and not-selected stores prior to the implementation of the plan (see Table 1) reveal that annual store manager turnover was three 9 Most top-tercile performing stores were run by store managers that had proven themselves in the past and that had either transformed a previously unproductive store into a top-performing store or had been moved to a high traffic store after proving themselves in a smaller market. 17 times larger in not-selected stores than in selected stores, but do not reveal any significant differences in other counterproductive outcomes (percentage of bad audits and absenteeism) between these two sets of stores during the pre-period. 10 While this may call into question the importance that management placed on additional criteria related to core values of the company (namely consistency of work and integrity), the managing director explained that the relevance of these criteria was emphasized after the preferential incentive plan was put in place. For example, the director recalled instances where she stripped stores of their right to receive daily bonuses due to behavioral issues and lack of trust. Further comparisons between selected and not-selected stores prior to the implementation of the plan reveal that selected stores were generally located closer to the head office, had about 3 more store-team members, were more likely to be located in premium areas, kept less days in inventory, and were more likely to be assigned higher ranked supervisors. Furthermore, a greater proportion of the store managers in the not-selected stores were of the Hindu religion (the most common religion among store managers) and/or called the National Capital Territory of Delhi their state of origin (the most common state of origin among store managers) compared to store managers in selected stores. 11 10 It is worth noting that the number of audit observations we could employ in this period was limited (with records for approximately two audits/store, and in a few cases 1 audit/store, during the pre-period). 11 Other store managers in the organization who were not from the Hindu religion or the National Capital Territory of Delhi state, were either from the Christian or Muslim religions, or reported to be from the states of Bihar, Uttar Pradesh, Rajasthan, or Uttarakhand. This information was gathered and provided to us by the Head of Human Resources of the company. 18 4. Empirical Analyses and Results 4.1 Comparison of Stores Where the Preferential Incentive Plan was Implemented vs. Stores Where It Was Not We use data from both the company-owned stores (“treatment” sample where the preferential incentive plan was implemented) and franchised stores (“control” sample where the plan was not implemented) to examine the effect of the introduction of the preferential incentive plan on sales performance. As Figure 2 shows, company-owned stores experienced a steeper increase in sales than franchised stores after the introduction of the preferential incentive plan. A noteworthy decline in sales among company-owned stores shown in Figure 2 in the month of December 2013 was explained by the managing director as a special circumstance when one of the company’s major suppliers of handsets temporarily withheld inventory from the company. We test the overall effect of the introduction of the preferential incentive plan on sales performance based on the following model: Ln (Sales)it = β0 + β1 Company-Owned Storei + β2 Post PIPt * Company-Owned Storei + β3 Premium Locationi + βn (Month-Year Fixed Effects)t + εit (1) where Ln (Sales) is the natural logarithm of the store sales for store i at time t (measured in month-years); Company-Owned Store is a dummy variable, indicating that the store belonged to the company-owned chain where the preferential incentive plan was implemented; Post PIP identifies the months after the preferential incentive was first introduced; and Premium Location identifies stores located in large markets, where high premium products were demanded. The results of our difference-in-differences analysis in equation (1) are presented in the first column of Table 2. Our results show that the introduction of the preferential incentive plan was associated with a 75% increase in store sales in company-owned stores relative to franchised 19 stores. 12 Hence we find support consistent with H1, which predicted that the introduction of the preferential incentive plan would have a positive effect on company outcomes. To further explore whether the association between the preferential incentive plan and the increase in sales in company-owned stores was driven by selected stores rather than not-selected stores, we rerun our analyses in equation (1), splitting our company-owned store variable into a dummy identifying company-owned stores that were selected to participate in the daily bonus scheme sometime during the sample period (Company-Owned Selected Store), and a dummy identifying company-owned stores that were never selected to participate in the scheme (Company-Owned Not-Selected Store) and rerun our analysis. Table 2, Column 2 suggests that the sales increase associated with the introduction of the preferential incentive plan was positive for both selected and not-selected company-owned stores. Furthermore, our test at the bottom of Table 2 also shows that the difference between the incremental sales associated with the introduction of the preferential incentive plan in selected and not-selected stores, relative to the control group, was positive but insignificant. Consistent with these findings, follow up interviews revealed that both selected and notselected store teams felt motivated not only by the monetary rewards but also by the managing director’s recognition and the sense of achievement that the store team could draw from being selected to receive the bonus. One of the store managers of a selected store explained: “When we got to know about the plan, the first thing we did was to hold a question/answer session to find out ways to achieve the target. There is always excitement when we realize that we can achieve a goal.” One of the store managers of a not-selected store indicated: “We took it positively. We were now thinking about strategy and were determined to not lose any customer. We understood our faults and tried to overcome them.” Although some of the store managers from not-selected 12 This is calculated based on the coefficient in Column 1 of Table 2 as (e0.562 – 1). 20 stores expressed disappointment for not being selected, rather than “giving up” they indicated a desire to double their efforts. Some reached out to store managers in selected stores to learn from them. The managing director indicated, “I think the daily incentive has a very big impact given that everything else was where it was. We did not make any changes [during the sample period]… the only intervention was the introduction of the daily incentives.” 13 Though our analysis in Table 2, Columns 1 and 2, suggests that the effect of introducing the preferential incentive plan in company-owned stores was positive regardless of whether the stores were selected or not to participate in the daily bonus scheme, our results may be driven by store specific characteristics or store trends omitted from the analyses. To evaluate the robustness of our results to these potentially correlated omitted variables, we replicate our analyses controlling for store fixed-effects and store-time trends. Untabulated results show that our main findings in Table 2 are robust to this alternative specification. Specifically, under this specification, the coefficient associated with the introduction of the plan is associated with an increase in sales that is 62% higher (Coef=0.483, t-stat=3.89) in company owned-stores than in franchised stores. Also, the introduction of the plan was associated with significant increases in the store sales of selected and not-selected company-owned stores, relative to franchised stores. In summary, the preferential incentive plan had a positive effect on the sales of both selected and not-selected company-owned stores (relative to the sales of franchised stores). 4.2 Factors Potentially Affecting the Association between the Preferential Incentive Plan and Store Outcomes Hypotheses 2 and 3 highlight factors that may affect the relative effectiveness of preferential incentive plans across different business units exposed to the plan (in our setting, this is the 13 Our understanding from the managing director’s comment was that the company did not make any “significant” changes to the incentive plans during our sample period. 21 sample of company-owned stores). Table 3 presents a correlation table that includes all the factors under consideration. The correlation table suggests that the company experienced an overall increase in sales and gross profit as well as a decrease in turnover following the implementation of the preferential incentive plan, and did not experience a significant increase in the percentage of bad audits or absenteeism. The next two sub-sections examine the effect of the different factors on the association between the introduction of the preferential incentive plan and store outcomes. 4.2.1 Factors Capturing the Need to Align Employees with Company Goals Hypothesis 2 highlights circumstances when the preferential incentive plan could yield greater benefits at the individual store level. To test this hypothesis, we examine whether the introduction of the preferential incentive plan provided greater benefits for stores located further from the head office (i.e., where, according to the managing director of the company, the potential to improve alignment with company goals was greater). Focusing on the subsample of company-owned stores, we run the following model: Outcomeit = β0 + β1 Distance to Head Officei + β2 Post PIPt × Distance to Head Officei + β3 Selected Storei + β4 Eligible Month for Selected Storeit + βm (Control Variables)it + βn (Month-Year Fixed Effects)t + εit (2) where, Outcomeit is measured either as a productive outcome (the natural logarithm of monthly store sales, Ln(Sales)it, or the natural logarithm of the estimated monthly store gross profit 14, Ln(Gross Profit)it), or a counterproductive outcome (percentage of bad audits, % Bad 14 During our sample period, MPR received additional commissions from Nokia and Samsung (called back-end sales commissions) for achieving pre-specified sales targets. For practical purposes, the company estimated the stores’ gross profits by adding to the upfront gross profit of each item sold, back-end sales commissions of 6% for Nokia handset sales and 9% for Samsung handset sales. 22 Audits 15, number of times the store manager had an unauthorized absence during the month, Absenteeismit, or a dummy capturing whether the store manager left the company within three months, Turnoverit). Our main variable of interest, Distance to Head Office, was measured as the number of miles between the store and the company headquarters. According to the director, employees in remote locations were less engaged and less aware of the company’s core values due to limited face-to-face interactions with the executives of the company. Consistent with this, Table 3 shows a negative correlation between the Distance to Head Office and both Sales and Gross Profit. In our multivariate analyses, we expected to find lower monthly Sales and Gross Profits, higher percentages of Bad Audits, and greater Absenteeism and Pr(Turnover), in stores located further from the head office. We also expected the introduction of the preferential incentive plan to mitigate these unfavorable effects of distance on outcomes. The model controls for various other factors defined in the Table 4 that could have affected changes in outcomes over time including eligibility (we include a store dummy, Selected Storei, identifying stores that became selected for the preferential incentive plan anytime during the period and a second indicator, Eligible Month for Selected Storeit, indicating the specific months when a store was selected to participate in the preferential incentive plan- we expected both of these indicators to be positively associated with productive outcomes and negatively associated with counterproductive outcomes), availability of resources (including the size of the store team, the number of days of inventory that the store had available, the store supervisor’s rank, the look of the store, and whether the store was located in a premium area or not); the store manager’s 15 We did not have access to the percentage of bad audit data for the entire period. Although the company systematically audited each store about once every two months throughout the sample period, it did not keep systematic records of its audits at the beginning of our sample period. This limited the number of observations we could employ (with records for approximately 2 audits/store, and in a few cases 1 audit/store, during the pre-period). 23 ability (measured by the presence of a manager at the store and the store manager’s tenure 16); other store characteristics including the store’s age, size and distance from the head office, and the store’s sales growth prior to the introduction of the preferential incentive plan; the number of days when the store was opened during the month, and time fixed effects (in month-years). Columns 1 and 2 of Table 4 show that the effect of “Distance to Head Office” on sales and gross profit was significantly negative prior to the introduction of the preferential incentive plan. A store’s sales and gross profits declined 3% with every mile that the store was located further away from the head office. 17 These negative effects, however, were fully offset once the preferential incentive plan was in place. Our results also suggest that the stores’ distance to the head office was associated with a higher incidence of bad audits (the percentage of bad audits increased an average of 2.6% with every additional mile between the store and the head office) but this effect too was offset after the preferential incentive plan was in place. We also find that, during the pre-period store manager turnover was higher (though at an insignificant level) in more distant stores, but that turnover among store managers of distant stores was significantly reduced after the preferential incentive plan was introduced. These results, suggesting that the plan had greater impact in stores that were further from headquarters, resonated with the managing director who indicated that store teams from remote stores were highly motivated by, and gained visibility with this, plan. She mentioned that store managers from distant stores let her know that they appreciated the award since it allowed them to be recognized and interact with her. While we found evidence that the distance to head office measure affected the impact that the preferential incentive plan had on sales, gross profit, 16 We used the cashier’s tenure if there was no store manager present in the store in the month. Notice the distance from headquarters was not necessarily a proxy for store traffic, as all stores were located in high traffic urban areas in Delhi. 17 24 incidence of bad audits, and store manager turnover, we found no evidence that it had a significant effect on the effect of the incentive plan on patterns of absenteeism at the stores. Among the control variables, we found that, as expected, stores that were selected had higher financial performance than those not selected throughout the sample period, and reduced their percentage of bad audits after the plan was implemented. With respect to store resources, we found that stores with larger teams generated greater sales and profits, but also suffered from greater manager absenteeism (possibly because store managers had greater opportunity to free ride when they were part of a larger team); stores located in premium areas recorded not only better financial performance but also lower absenteeism; and stores with more days in inventory suffered from greater turnover (perhaps due to lower inventory turnover). With respect to the store managers’ ability, we found that stores with longer tenured managers sold more and experienced less manager turnover, but also had more bad audits. Similarly, stores with a store manager (as opposed to no store manager) had more bad audits. It’s possible that experienced store managers knew the system better and hence had greater opportunities to misbehave. Other store characteristics were also important predictors of outcome variables. Specifically, store size and sales days were associated with greater sales; store age was associated with greater sales, greater gross profits, and lower turnover; and sales days was associated with greater absenteeism. Interestingly, we found an association between pre-period sales growth and both absenteeism and turnover. Overall, our results suggest that the preferential incentive plan contributed to motivating employees working in remote stores to sell more, to generate greater profits, to produce more favorable audit results, and to stay with the company. 25 4.2.2 Factors Potentially Affecting Perceptions of Inequities Associated With the Preferential Incentive Plan Hypotheses 3a and 3b state that employees in not-selected stores who may consider the right to participate in the daily bonus scheme to be either unattainable or inequitable, might become demotivated by it. Hypothesis 3a posits that perceptions of unattainability or inequity may arise in not-selected stores receiving fewer resources to “compete” than their peers. On the flip side, not-selected stores receiving greater resources should have reacted relatively more favorably to the preferential incentive plan since they may have perceived a higher likelihood of becoming selected and may not have perceived that they were treated unfairly. According to the managing director of the company, the main resources contributing to a store’s performance are the store team size, the store’s location (whether or not it is located in a “premium area”), the inventory available for sale at the store, and the ranking of the store’s supervisor. 18 In support of the director’s claims, Table 3 shows that most of these factors are positively correlated with productive outcomes (sales and gross profit performance). Consistent with the notion that employees from stores receiving fewer resources might perceive they had been treated unfairly, we find that some of these factors are negatively correlated with counterproductive outcomes (specifically bad audits). Two exceptions to these patterns were that “team size” was positively associated with (store manager) absenteeism, and “days of sales in inventory” was negatively associated with financial performance. The association between team size and store manager absenteeism may suggest that store managers had greater opportunities to “free-ride” when their store teams were large. The negative association between “days of sales in inventory” and financial performance may be explained by the fact that our 18 Notice that we don’t include the “New Store Look” variable in this list. This is because only one of the “notselected” stores had a “new look.” 26 “days of sales in inventory” proxy captured both the stock available but also the sales activity at a store. Regardless of whether resources were positively or negatively associated with performance, we expected stores having greater resources to have a more favorable response to the preferential incentive plan. We examine the extent to which these resources affected the impact of the preferential incentive plan on not-selected stores, by testing the following model 19: Outcomeit = β0 + β1 Team Sizeit + β2 Premium Locationi + β3 Days in Inventoryi + β4 Supervisor Rankingit + β5 Pre-Period Proximity to Targeti + β6 Post PIPt × Team Sizeit + β7 Post PIPt × Premium Locationi + β8 Post PIPt × Days in Inventoryi + β9 Post PIPt × Supervisor Rankingit + β10 Post PIPt × Pre-Period Proximity to Targeti + βm (Control Variables)it + βn (Month-Year Fixed Effects)t + εit (3) The definitions of all the variables in equation (3) are the same as those in equation (2). Additionally, following the prior tournament literature which has found that contestants that are far from winning lose motivation (Casas-Arce and Martínez-Jerez [2009]), we controlled for the frequency with which the not-selected store reached 95% of the minimum sales threshold 20 to be considered to participate in the daily bonus scheme before the introduction of the plan (PrePeriod Proximity to Target). Table 5 shows some evidence generally consistent with H3a, which predicted that the resources received by the stores would significantly affect the impact that the preferential incentive plan would have on productive and counterproductive outcomes. Column 1 shows that the preferential incentive plan was associated with greater sales in stores with larger team sizes. 19 Some of these resource variables were correlated with each other, though their correlations were not high enough to justify the estimation of latent factors (via principal components or factor analysis). Variance inflation factor analyses revealed no multicollinearity concerns for any of the regressions presented in the tables. 20 Our results are robust to controlling for the frequency with which not-selected stores reached 80% of the minimum sales threshold. 27 Column 2 shows increasing gross profits following the introduction of the preferential incentive plan in stores with greater inventory available (measured as the number of days in inventory). The preferential incentive plan was associated with a 6.9% increase in monthly sales for every additional team member at the store and a 2.4% increase in monthly gross profit for every additional day of sales in inventory. Column 4 shows that the introduction of the preferential incentive plan was associated with a one day reduction in a store manager’s unauthorized monthly absenteeism for each additional 14 days of sales inventory held at the store. 21 Finally, column 5 shows that the store managers’ likelihood of leaving the store decreased after the introduction of the preferential incentive plan in stores located in premium locations, stores overseen by higher ranked supervisors, and stores holding a greater number of days of sales in inventory. Our interviews with store managers revealed that managers from not-selected stores attributed their not being selected to not having enough stock (yet we found those stores generally had greater days of sales in inventory than selected stores 22) or being in areas with less customer walk-ins. The interviews also suggested that store managers from not-selected stores were less active at reaching out to their supervisors than their counterparts in selected stores. A store manager of a not-selected store indicated that although his store team reacted positively to the plan, the members in the store were “complaining about stock issues and saying that customer walk-in was not much.” One of the store managers of a selected store indicated: This scheme is given to maximum performing stores and it depends upon them to qualify for it. Now the person who is positive will take it positively and the one who is negative will only talk in a negative way. Those with positive attitude only 21 We estimate this by dividing 1 by the coefficient 0.071. It may be that those stores were concerned about the absolute value of stock they were provided with, rather than days of sales in inventory. 22 28 care about sales and customers. They have to sell the products they have been given to sell. The negative attitude people just keep complaining that they are not getting stock and they have pricing issues. But still the majority of them remain positive. Although all the results described above support Hypothesis 3a, we found two results inconsistent with this hypothesis: (a) we found that store managers of stores with larger team sizes were more likely to leave (rather than stay with) the store following the introduction of the preferential incentive plan, and (b) we did not find evidence that resources affected the impact that the preferential incentive plan had on bad audits. Our next hypothesis (3b) suggested that perceptions of inequity (discrimination) may have emerged if the store managers of not-selected stores noticed that their social identity groups (e.g. groups affiliated to their same religion or state of origin) were underrepresented among the store managers of selected stores. This could easily have happened since the correlations between the company’s main social groups and performance were significant (see Table 3), suggesting some groups were more likely to be selected than others. Hypothesis 3b examines whether instances where underrepresentation existed affected the impact of the preferential incentive plan on store outcomes. We test this idea by regressing: Outcomeit = β0 + β1 Store Manager’s Religion Underrepresented among Selected Stores At Any Timei + β2 Store Manager’s State Underrepresented Among Selected Stores At Any Timei + β3 Pre-Period Proximity to Targeti + β4 Store Manager’s Religion Underrepresented Among Selected Stores this Monthit + β5 Store Manager’s State Underrepresented Among Selected Stores this Monthit + β6 Post PIPt × Pre-Period Proximity to Targeti + βm (Control Variables)it + βn (Month-Year Fixed Effects)t + εit (4) 29 The definitions of all the variables in equation (4) are the same as those in equation (3), but we add indicator variables to identify stores where the store managers’ religion and/or state of origin were underrepresented among store managers of selected stores. These indicator variables are defined both at a store level to identify stores experiencing the underrepresentation of their store managers’ social identity group anytime during the post period and at the store-month level indicating the precise months when this underrepresentation emerged (detailed definitions of the indicator variables are provided in Table 6). 23 Table 6 provides some support for H3b. Column 1 shows an incrementally negative effect of the preferential incentive plan on sales, whenever the not-selected store manager’s state of origin was underrepresented among selected stores. Columns 2 and 3 suggest the preferential incentive plan is associated with a decrease in gross profit and an increase in bad audits in stores where the store manager’s religion was underrepresented among the selected stores. Although the managing director had not been aware that the preferential incentive plan could affect parties that were underrepresented, she commented “I can definitely see that this [underrepresentation of religion and state of origin] matters a lot in India. I’ve seen that religion matters. I’ve seen their perception of equity matters… [for example] if I’m rewarding only Hindus and there is no Muslim representation in the party, I do think it matters… it is very important but it’s unsaid.” Notwithstanding the results above, we did not find evidence that the under-representation of any of the store managers’ social groups affected the extent to which the preferential incentive plan affected the store managers’ absenteeism or turnover. In summary, our results provide some evidence that factors potentially affecting perceptions of inequities, due to differences in the resources each store team had to perform their job and 23 Muslims were under-represented in only one month in the post period; with the exception of that month, Hindus were under-represented in all months in the post period; Christians were never under-represented in the post period (in fact, only one store manager was of the Christian religion). 30 differences in the social identity composition of not-selected and selected store managers, affected the impact that the preferential incentive plan had on the stores’ outcomes. 5. Conclusions This paper studies a class of incentive contracts, “preferential incentive plans,” consisting of (a) a tournament component, where a manager assesses whether each of a limited number of topperforming employees or teams (identified through the use of objective performance metrics) should be selected for additional incentives; and (b) an incentive component, where “selected” employees/teams become eligible to receive bonuses awarded based on objective performance metrics. These plans could arise in different settings where exemplary employees are given opportunities to receive increased earnings from (a) their existing incentive plans (for example, situations where the bonus rates of exemplary employees are increased, or natural settings like restaurants or sales jobs where top performing employees receiving tips or commissions are assigned to the most lucrative shifts or customers) or (b) incentive plans specifically designed to reward exemplary employees (for example, stock options or, as in our MPR setting, bonuses applying exclusively to exemplary employees). These plans could be beneficial in incomplete contract settings, where a company may want to motivate employees to pursue not only objectively measured goals but also relevant tasks not explicitly included in their contracts. By incorporating a selection step (subject to managerial discretion) to determine the employees’ participation in a bonus, the company could encourage employees to perform in the spirit of the plan and the broader objectives of the company. However, preferential incentive plans could lead to unintended consequences if they trigger perceptions of inequities. 31 We examine the effects of the preferential incentive plan in MPR and find that the introduction of the plan was associated with increases in sales performance relative to a control group where the preferential incentive plan was not implemented. These increases in sales were present both in selected and in not-selected stores participating in the preferential incentive plan. Although our tests are conducted using data from a single company, our analyses reveal some of the factors that can impact the effectiveness of a preferential incentive plan. Specifically, we show that such plans can be most beneficial as the need to align employees to overall company goals increases (in our setting, we find that store teams that were most disconnected from company values due to their geographic distance from the head office benefitted the most from the implementation of the plan). We also find that preferential incentive plans could be least beneficial (or possibly even harmful) in situations where teams could perceive the plan to be unattainable or unfair. We show that, in MPR, not-selected stores receiving fewer resources to do their job, or led by store managers whose social identity was underrepresented among managers of selected stores, decreased their sales and gross profit performance and increased their bad audits following the introduction of the preferential incentive plan. The consideration of these factors may allow the reader to assess whether the payoffs from using preferential incentive plans would be more or less beneficial in other settings beyond MPR. These findings suggest that preferential incentive plans can motivate employees to exert effort not only on objectively measured tasks incorporated in their contracts, but also to attend to relevant tasks not explicitly included in their incentive contracts which could be essential to a company’s objectives (e.g., trustworthiness, consistency). This finding contributes to prior research studying the use of promotions or tournaments, and subjective assessments, as complements to incomplete incentive contracts (e.g., Gibbs et al. [2004], Campbell [2008]). 32 Our insights also contribute to the equity theory and social identity literatures by highlighting the role that equity concerns may play in the effectiveness of incentive contracts that incorporate subjective assessments and tournament-like features. Our study provides a plausible explanation for the avoidance of subjective incentives and tournament plans in firms where the inputs provided to different workers cannot be easily distributed or where differences in the abilities of social identity groups represented in an organization may trigger perceptions of inequities in preferential incentive plans. The results of this study should be interpreted with caution. The fact that our study was conducted in a single company suggests that there may have been some critical factors associated with the firm that enabled the preferential incentive plan to be effective. For example, the selection decisions granting top stores the right to participate in the bonus plan were made by the managing director of the firm, who is highly trusted and respected by the store managers. Gibbs et al. [2004] highlight that subjective incentives cannot be effective in the absence of trust. The fact that we studied this phenomenon in a single firm prevented us from studying in greater detail how elements of preferential incentive plans, including the percentage of top performers rewarded or the extent of managerial discretion applied in the selection process, affect the effectiveness of such plans. These inquiries could provide promising opportunities for future research. 33 6. References ABERNETHY, M. A., H. C. DEKKER, AND A. K-D.

A noteworthy decline in sales in the month of December 2013 was the result of one of the company’s major suppliers of handsets temporarily having a conflict with, and withholding inventory from, the company. 38 Table 1: Summary Statistics by Type of Store (“Selected” or “Not-Selected”) Before the Introduction of the Preferential Incentive Plan Pre-period mean Pre-period mean Not-selected Difference in Selected stores stores means Sales 1,861.715 441,671 1,420,044*** 100,800 22,749 78,051*** % Bad Audits 70% 73.9% -3.9% Absenteeism 1.11 0.65 0.46 Annual Store Manager Turnover 23% 75% -52%*** Distance to Head Office 7.39 9.61 -2.22*** Team Size 9.27 5.81 3.46*** Premium Location (Dummy) 1.00 0.40 0.60*** Days in Inventory 20.16 24.34 -4.18*** Supervisor Ranking 3.34 2.11 1.23*** Store Managers with Hindu religion 0.39 0.66 -0.27*** Store Manager from the National Capital Territory of Delhi State 0.55 0.35 0.20*** Gross Profit *, **, *** denote significance at a 0.10, a 0.05 and a 0.01 level, respectively. Sales is monthly store sales in Indian Rupees. Gross Profit is monthly store gross profit in Indian Rupees. Store gross profits were estimated by adding the upfront gross profit of each item sold, plus back-end sales commissions of 6% for Nokia handset sales and 9% for Samsung handset sales. % Bad Audits is the percentage of times the result of an audit was “bad” (i.e., revealed at least one missing item or cash shortage without a reasonable explanation) at the store in the month. Annual Store Manager Turnover is the number of store managers that left the store in the pre-period year, divided by one (since there is one store manager position per store), and multiplied by 100%. Absenteeism is the number of unauthorized days the store manager was absent from the store in the month. Distance to Head Office is distance to the head office in miles. Team Size is the number of individuals working in the store in the month. Premium Location (Dummy) is a dummy equal to 1 if the store is located in a large market, where high premium products are demanded (these locations were identified by the managing director). Days in Inventory is the average days in inventory at the store calculated by dividing the value of inventory "in stock" at the store by the average cost of goods sold in one day. 24 Supervisor Ranking is a variable equal to 0 if the store is not overseen by any head office 24 This variable was estimated using off-sample data from October 2014 - May 2015. The inventory values were obtained on the 15th of each month and the daily costs of goods sold were averaged for every month. Differences across days of inventory of sales are stable over time, suggesting the use of this off-sample variable is reasonable. In cases when we did not have data because the store had closed, we assumed that the store had as many days in inventory as a store at the lowest 25th percentile "days of inventory" in the same area. When asked about our construction of this measure, the managing director indicated “is very reasonable because things wouldn’t change, not at all. For example Nehru Place would always be loaded and the smaller stores would always be unloaded.” 39 manager; 1 if the store is overseen by a district-manager-in-training; 2 if the store is overseen by a district manager; 3 if the store is overseen by the managing director; 4 if the store is overseen by both a district manager and the managing director.

We assumed that those 12 store managers had been employed for 37 months as of February of 2012 (approximately the average tenure=37.7 for the other store managers for whom we had data as of February of 2012). 48 Table 6: Coefficients of OLS or Logit Regressions Showing the Moderating Effect of Social Identity on the Association Between the Introduction of the Preferential Incentive Plan and Not-Selected Store Outcomes (Sample Comprises Not-Selected Company-Owned Stores) Productive Outcomes (1) (2) VARIABLES Pred.

Observations R-squared Col 1-4/ Pseudo R-squared Col 5 t-statistics based on robust standard errors adjusted for store clusters in parentheses. *, **, *** denote significance at a 0.10, a 0.05 and a 0.01 level, respectively (p-values are one-tailed for directional predictions and two-tailed otherwise). After the preferential incentive plan was introduced, we determined whether the group “X” a store manager of a store “i" belonged to (either Muslim, Christian, or Hindu when referring to Religion, or Bihar, the National Capital Territory of Delhi, Rajasthan, Uttar Pradesh or Uttarakhand when referring to State) was underrepresented among the selected stores, based on the following steps: Step 1: We estimated for every month-year t: # π π π π π ππππππππ ππ πΊπΊπΊπΊπΊ ππ‘ Expected # store managers of Group X in selected storest= Round οΏ½# π π π π π ππππππππ ππ π π π π π π π π π π π π π π π‘ ∗ οΏ½ οΏ½οΏ½ π‘π‘π‘π‘π‘ # π π π π π πππππππππ‘ Step 2: We then estimated for month-year t: Underrepresentation of Group X among store managers of selected storest = min [0 , (Expected # store managers of Group X in selected storest - Actual # store managers of Group X in selected storest)] Step 3: We determined whether the store manager of store i at time t was underrepresented if the group “X” he belonged to was underrepresented on that month-year t. In other words: Underrepresentation of Group X among store managers of selected storest > 0 Store Manager’s Religion Underrepresented Among Selected Stores At Time t is a dummy equal to 1 if the store manager’s religion was underrepresented in month-year t among store managers of selected stores. Store Manager’s Religion Underrepresented Among Selected Stores At Any Time is a store-level dummy equal to 1 if the religion of any of the store managers working at the store was underrepresented among store managers of selected stores in any month during the post period (in other words; this dummy is equal to 1 throughout the period for any store for which the preceding dummy was equal to 1 at any time). Store Manager’s State Underrepresented Among Selected Stores At Time t is a dummy equal to 1 if the store managers' state of origin was underrepresented in month-year t among store managers of selected stores. Store Manager’s State Underrepresented Among Selected Stores At Any Time is a store-level dummy equal to 1 if the state of origin of any of the store managers working at the store was underrepresented among store managers of selected stores in any month during the post period (in other words, this dummy is equal to 1 throughout the period for any store for which the preceding dummy was equal to 1 at any time). 50 Ln(Sales) is the natural logarithm of monthly store sales in Indian Rupees. Ln(Gross Profit) is the natural logarithm of monthly store gross profit in Indian Rupees. % Bad Audits is the percentage of times the result of an audit was “bad” (i.e., revealed at least one missing item or cash shortage without a reasonable explanation) at the store in the month. Absenteeism is the number of unauthorized days the store manager was absent from the store in the month. Turnover is a dummy equal to 1 if the store manager left the company within 3 months (at time t, t+1, or t+2). Pre-Period Proximity to Target is the average number of days in the month where sales >= 95,000 for the 12-month period prior to when the preferential incentive was first introduced. Post PIP (Dummy) is a dummy equal to 1 if the observation is in the period after the preferential incentive plan was first introduced. Team Size is number of individuals working in the store in the month. Premium Location (Dummy) is a dummy equal to 1 if the store is located in a large market, where high premium products are demanded (these locations were identified by the managing director). Days in Inventory is the average days in inventory at the store calculated by dividing the value of inventory "in stock" at the store by the average cost of goods sold in one day. 30 Supervisor Ranking is a variable equal to 0 if the store is not overseen by any head office manager; 1 if the store is overseen by a district-manager-in-training; 2 if the store is overseen by a district manager; 3 if the store is overseen by the managing director; 4 if the store is overseen by both a district manager and the managing director. Store Manager Present in Store (Dummy) is a dummy equal to 1 if a store manager was present in the store in the month. Store Manager Tenure is tenure of the store manager in months since joining the company (or tenure of the cashier if the store manager was not present). 31 Pre-Period Sales Growth is average monthly store sales growth for the 12-month period prior to when the preferential incentive was first introduced. Distance to Head Office is the distance to the head office in miles. Store Size is store size in square feet. Store Age is store age in years. Sales Days is the number of days in the month when the store made sales. 30 This variable was estimated using off-sample data from October 2014 - May 2015. The inventory values were obtained on the 15th of each month and the daily costs of goods sold were averaged for every month. Differences across days of inventory of sales are stable over time, suggesting the use of this off-sample variable is reasonable. In cases when we did not have data because the store had closed, we assumed that the store had as many days in inventory as a store at the lowest 25th percentile "days of inventory" in the same area. When asked about our construction of this measure, the managing director indicated “is very reasonable because things wouldn’t change, not at all. For example Nehru Place would always be loaded and the smaller stores would always be unloaded.” 31 We replaced “Store Manager Tenure” missing values for 106 observations (from our sample of 2,171 observations) corresponding to 12 store managers that were already present at the beginning of our sample period (in February of 2012), but for which we did not receive their store manager starting date from the company. We assumed that those 12 store managers had been employed for 37 months as of February of 2012 (approximately the average tenure=37.7 for the other store managers for whom we had data as of February of 2012). 51
