These institutions are established for helping the poor to raise income levels and to reduce poverty. Recently, MFIs are required to reduce their dependence on grants and subsidies. Consequently, they face conflicting objectives of improving reach and profitability. These can be achieved by improving productivity. This paper aims to investigate productivity change in 21 major MFIs in India which are rated by Credit Rating and Information Services of India Limited in 2014. Design/methodology/approach – This paper attempts to examine total factor productivity change in 21 major Indian MFIs during the period from 2014 to 2016 using Malmquist productivity index. The inputs and outputs are selected considering objectives of outreach and financial sustainability. The authors have categorized MFIs in three categories, namely, large, medium and small, depending on asset size. Findings – It is revealed that large MFIs are able to catch up with industry best practices by improving their systems and processes, but they need to improve scale efficiency. The Reserve Bank of India has recently initiated a policy of granting banking licenses to those financial institutions which have good outreach and are financially strong. It can be used for shortlisting MFIs before granting permission to operate as banks. The method can also be used for benchmarking them for productivity. It can also be replicated in other countries. Originality/value – In India, MFIs are playing important role in economic development by providing microcredit to the poor. However, very few studies have been undertaken regarding productivity of MFIs in India. The present study intends to fill this gap. It will facilitate benchmarking of MFIs as competitive and sustainable financial institutions catering to the requirements of small borrowers.

Introduction Microfinance industry is growing all over the world as it is attracting large sums of public and private investments and most of these investments are “for-profit” (Copestake, 2007). Several microfinance institutions (MFIs) are scaling up and a few of these have been JEL classification – D24, G21 Indian Growth and Development Review © Emerald Publishing Limited 1753-8254 DOI 10.1108/IGDR-12-2017-0105 Downloaded by Stockholm University Library At 08:34 08 December 2018 (PT) IGDR converted to banks especially in Latin America (Drake and Rhyne, 2002). To attract commercial funds for scaling up, it is necessary to focus on financial performance and MFIs run the risk of neglecting the social mission in the process (Greeley, 2006). Cull et al. (2009) observe the necessity of commercial investment in microfinance industry and remark that such institutions, with robust social mission, are in the best position to serve the poorest of the poor. The authors observe that though the market is a strong force, the poor will not be served without appropriate interventions. Anyanwu (2004) identifies several challenges of growth to MFIs in Nigeria, such as funding, sustainability and regulatory framework. González Vega (1998) observes that MFIs face major challenges due to competition, state intervention, systemic risks and improper regulation. The rapid expansion of loan portfolio increases credit default risk due to faulty assessment. Moreover, expansion in new geographical areas involves higher infrastructure cost. So there is also a risk of lapses in monitoring of loans due to burden on the system. Therefore, fast growth is likely to weaken sustainability and there is a possibility of losing focus on mission. Thus, ensuring healthy growth is a tough challenge before MFIs in India and elsewhere (Schreiner et al., 1996). MFI managers have to balance financial efficiency with the objective of providing quality services to the poor and it is a challenge for regulators to provide regulatory framework which will facilitate scaling up of microfinance with a focus on mission (Ahmed, 2005). Microfinance sector in India, boosted by large scale private and foreign funds, experienced a rapid growth during 2005 to 2010. High growth exposed microfinance industry to various risks leading to serious irregularities such as, multiple lending, exorbitant interest rates and use of coercive means of recovery. In 2010, Andhra Pradesh Government curbed the activities of MFIs, which led to crisis in microfinance industry in India. After the crisis, MFIs in India had taken several steps to improve productivity such as use of information technology, rationalization of network and setting up of self-regulatory organization. In 2012, the Reserve Bank of India had also issued regulatory guidelines. Microfinance sector had recovered from the crisis by 2012 and had picked up further rapid growth (IFMR Investments, 2014). During the period from 2012 to 2016 gross loan portfolio of microfinance industry in India grew by 376 per cent from Rs 111.83bn to Rs 532.33bn (Micrometer, 2016). In 2015, RBI has granted “in principle” licenses 10 MFIs for working as small finance banks (SFBs). In the new competitive environment, there will be pressure on profitability of SFBs. It is likely that these will lose focus on financing the poorest of the poor. This paper examines the question: Q1. Whether microfinance industry in India is undergoing mission drift in the process of scaling up? It is necessary for MFIs to be financially efficient with a focus on financing the poor. Moreover, few studies have concluded that financial sustainability and social efficiency can both be achieved (Mersland and Strøm, 2010; Quayes, 2012; Louis et al., 2013). This paper also attempts to provide a metrics to managers of MFIs, SFBs and regulators that will help them measure the financial sustainability without losing focus on financing the poor; especially during the period of growth. 1.1 Measurement of productivity Productivity may be measured using a single factor index or a multi-factor index. However, the single factor index is not an appropriate measure of the productivity of a firm because there are multiple inputs/outputs and multiple factors affecting the productivity of a firm. Downloaded by Stockholm University Library At 08:34 08 December 2018 (PT) Schreiner et al. (1996) attributes the success of Banco Sol to multiple factors such as its improved operational efficiency, development of appropriate technology and efficiency of scale while it was facing challenges that come with scaling up and rapid growth. Malmquist productivity index, which is a multi-factor productivity index, comprises three indices namely, technology change index, technical efficiency change (TEC) index and scale efficiency change index and is a robust and appropriate measure of sustainable, multi-factor productivity. We have used the Malmquist multi-factor productivity index to measure the productivity of selected MFIs. The inputs considered are, own funds and long term borrowings whereas loan amount outstanding and profit are taken as outputs. Productivity of MFIs is found to be impacted by several factors such as profit motive, geographical reach, business model and market share. This measure of productivity confines itself to measuring financial sustainability only; whereas, MFIs have the dual objectives of achieving profitability and serving the poorest of poor. Gebremichael and Rani (2012) observe that the objectives of double bottom line are apparently conflicting in nature. Therefore, pursuit of financial sustainability alone will cause the firm to drift away from the mission of financing the poor. So, a measure of productivity capturing both dimensions will be a more comprehensive reflection of productivity. To examine mission drift, we use four parameters, namely average loan size, market (rural/urban), focus (favorable bias towards women), lending methodology (group/ individual) as identified by Mersland and Strøm (2010). We found that there is a strong mission drift in pursuit of financial sustainability. To measure productivity comprehensively, we have developed an evaluation metrics combining the Malmquist index along with the parameters suggested by Mersland and Strøm (2010) which captures both financial sustainability and the extent of mission attainment. This will help the MFIs design a strategy to strike a balance between the conflicting objectives of ensuring sustainability, while simultaneously controlling mission drift during the period of high and rapid growth. This tool will also be useful for MFIs in establishing internal controls. Further, this tool will allow the MFIs to identify the better performers in the industry. In addition, regulatory bodies may use this tool for shortlisting MFIs for licensing as SFBs. The study is important because in the absence of benchmarking, internal controls and robust regulatory framework; microfinance industry in India is likely to lose focus and plunge into another crisis. As revealed through literature, very few studies have been undertaken regarding productivity of MFIs in India. The present study intends to fill this gap. We have studied the productivity change in 21 major MFIs in India (with 2012 as base year), which are rated by Credit Rating and Information Services of India Limited (Ratings, 2014). The sample constitutes 80 per cent of the market share measured by gross loan portfolio. This section is followed by literature review and Section 3 explains the methodology. Section 4 contains findings and discussions and Section 5 deals with conclusion and policy implications. 2. Literature review The mission objectives of MFIs are to offer a wide range of services such as micro credit, micro insurance and micro pension. Littlefield et al. (2003) observe that microfinance creates Malmquist productivity index Downloaded by Stockholm University Library At 08:34 08 December 2018 (PT) IGDR wider socio-economic impact on the lives of the poor. Improvement in income levels of the poor enables them to invest in children’s education and health. In addition, female clients of MFIs become more confident with an increase in their income levels and their say in household matters increases. This also enables them to fight gender inequalities in a better way. Therefore, scaling up and growth of microfinance is necessary for achievement of mission objectives. Microfinance industry was dependent on grants and subsidies in early stages of its development. However, of late, there is pressure on MFIs for reducing dependence on these sources of finance and becoming financially self-sustainable. In the process of achieving sustainability and scaling up, some MFIs are drifting from their mission which reflects in their preference to increase profitability rather than to serve the poorest of the poor (Rauf and Mahmood, 2009). As a result, they are financing marginally poor or non-poor and are excluding extremely poor people. Muhammad Yunus (2011) commented that commercialization is a worrisome “mission drift” for MFIs. As such, MFIs face challenges of double bottom line viz. increasing outreach by providing financial services to the poor and at the same time maintaining financial sustainability (Hartarska, 2005; Otero, 1999; Brau and Woller, 2004). 2.1 Mission drift Growth and scaling up of microfinance programs in India and elsewhere, are necessary, as it is beneficial to the poor. However, commercial funding which is required for scaling up, can result in excessive focus on profit at the cost of social objectives. So also, growth comes with inherent challenges causing strain on profitability which may also lead to willing or unwilling sacrifice of social objectives by MFI managers. Hishigsuren (2007) has studied mission drift in respect of a microfinance organization which serves poor women in rural India. The author found that mission drift of that organization is not a planned decision of management but it is an outcome of the scaling up process and the challenges that came with it. However, some authors support the view that so long as there is overall poverty reduction, there is no mission drift and MFIs need not necessarily serve the poorest of the poor. Ghosh and Van Tassel (2008) offer theoretical explanation to the phenomenon of “mission drift”. They observe that to be sustainable, MFIs move its portfolio from the poorest of the poor to the less poor borrowers. This results in high profitability which in turn increases their capability for reduction in poverty on a larger scale. Serrano-Cinca and Gutiérrez-Nieto (2014) observe that mission of MFIs is poverty reduction and women empowerment with a focus on rural people. The authors have observed a mission drift in case of some MFIs. In the process of scaling up and ensuring financial sustainability, MFIs may drift from their mission. However, some studies have found that objectives of financial and social efficiency are not necessarily inconsistent with each other. Salim (2013) has studied objectives of profitability and poverty reduction in respect of two largest MFIs operating in Bangladesh. The study reveals that the choices of branch locations were driven more by poverty reduction parameters rather than those of profit maximization. Quayes (2012) has studied the relationship between financial self-sustainability and the depth of outreach of MFIs in respect of 702 MFIs from 83 countries. It was found that increase in outreach has positive relationship with financial sustainability. The study concludes that attainment of financial sustainability is not a hindrance for achieving better outreach. Downloaded by Stockholm University Library At 08:34 08 December 2018 (PT) Louis et al. (2013) have examined whether increased focus on sustainability reduces social impact of MFIs or otherwise. Contrary to the concerns, the study found that financial efficiency is positively related with social efficiency. Mersland and Strøm (2010) have studied mission drift in microfinance industry in the world spanning 11 years (1998-2008). The authors have studied “rated” MFIs in 74 countries using average loan size, market (Rural/Urban), bias towards women and lending methodology (individual vs group) as mission parameters. They have found that there was no evidence of mission drift. 2.2 Measuring efficiency of microfinance institutions Many researchers have considered outreach and sustainability as the two most important parameters to assess the performance of MFIs. Table I gives details of parameters used by various researchers for measuring efficiency of MFIs. There are two approaches to measuring efficiency of MFIs, namely, production approach and intermediation approach (Wijesiri et al., 2015). The production approach considers these institutions as firms which create financial products and services using manpower, materials, technology and related costs. The intermediation approach, on the other hand, views them as intermediaries which convert labor and capital into loans for the borrowers. Irrespective of the approach, the productivity of MFIs should be measured on both parameters, namely, social efficiency and financial sustainability (Mersland and Strøm, 2009). The researchers have used number of persons, expenses or costs and/or total assets as inputs. Data envelopment analysis (DEA) methodology considers a production-like environment, in which inputs are converted to output. In a production process, inputs (as envisaged in DEA) are considered identical in terms of utility. However, this does not apply to persons working in an organization, as every person is different and has different capabilities; moreover, these capabilities are subject to growth or diminution depending on motivational factors. As such, number of persons in different organizations, as an input, is not comparable and hence inappropriate. Also, the researchers have not measured the efficiency with respect to the financial sustainability and mission objective distinctly. The researchers have found that financial sustainability and mission objectives are not necessarily in dissonance with each other and that there are microfinance programs across different parts of the world which are financially and socially efficient. This paper attempts to measure the efficiency of MFIs considering both parameters namely, financial sustainability and attainment of mission objectives, during the period of high and rapid growth. To measure financial sustainability, the authors have considered financial intermediation approach. As per this approach, MFIs convert capital and borrowings (Liabilities/Resources) into loan portfolio, thus generating profit. In India, MFIs are not allowed to accept deposits. Therefore, capital and long term borrowings are appropriate inputs. The inputs such as cost or expenses are considered while arriving at the profit. To measure the attainment of mission objectives the authors have considered the ratio of average loan size of MFIs to the average loan size of the industry, market coverage (urban, rural), gender and lending methods as suggested by Mersland and Strøm (2010). Serrano-Cinca and Gutiérrez-Nieto (2014) also observe that mission drift measured in terms of increase in loan size is in consonance with objective of poverty reduction.

Higher outreach is associated with higher efficiency which negates the general perception of trade-off between outreach and efficiency. Regulated MFIs are less efficient Ahmad (2011) Total assets and Gross loan portfolio and Number of personnel Number of active borrowers MFIs from South India have positive correlation with technical efficiency. This may be due to early development of MFIs in the southern states, conducive atmosphere, Government support and policy of promoting microfinance as a poverty alleviation tool. The statistical significance of business per staff and log (total asset) indicate the need for scaling up of MFIs to become efficient Masood and Ahmad (2010) Number of personnel and Gross loan portfolio Cost per borrower Bank-MFIs outperform NGO-MFIs under intermediation approach. This may be the result of access of banks to local capital market Pal (2010) Number of credit officers and Three year average outstanding loan portfolio Cost per borrower The source of inefficiency is pure technical rather than scale, suggesting that MFIs are either wasting resources or are not producing enough output Haq et al.

Methodology As per OECD productivity manual (2001), the term total factor productivity (TFP) is synonymous with multifactor productivity (Schreyer, 2001). The TFP is an outcome of two major factors namely efficiency and technological change. The present study measures change in TFP of 21 MFIs in India during the period 2012 to 2016. We have used Malmquist productivity index which is a multifactor productivity index. It is a chain index involving comparisons with consecutive periods. The index measures smaller changes and thus it is meaningful (Coelli et al., 1998). Further, this index is split into three indices, namely, technology change index, TEC index and scale efficiency change index. The technology change index reveals the change in productivity due to advancement of technology of the industry as a whole. TEC index indicates how well the firm has caught up with the best practices of the industry. Scale efficiency change index highlights change in efficiency due to scaling up of operations. Thus the indices provide insights to the management regarding the areas in which inefficiencies are emerging. 3.1 The Malmquist productivity index and change index We have followed output-oriented Malmquist productivity change index as suggested by Fare et al. (1994). It does not require information regarding input-output prices. Moreover, the index permits division of TFP change into two components, namely, TEC and technical change (TC). The TEC means catching up by the firm with the best practices of the industry, and TC is change in the best practice or change in technology. The TEC can be further divided into pure TEC and scale efficiency change. The index calculation uses DEA for calculation of various distance functions. The Malmquist Productivity Index (MPI) measures TFP change between two data points by calculating the ratio of the distances of each data point relative to a common technology. Thus MPI at time t with reference technology St (CRS)t is: Dt xtþ1 ; ytþ1 =Dt xt ; yt (1) and at time t þ 1 with reference technology Stþ1 (CRS)tþ1 it is: Dtþ1 xtþ1 ; ytþ1 =Dtþ1 xt ; yt (2) These are explained with the help of Figure 1. Malmquist productivity change index is defined as geometric mean of two indices at the times t and t þ 1. MPI Change index = Geometric mean of ratios of equations (1) and (2): hh i h tþ1 tþ1 tþ1 tþ1 t t ii1=2 * D Dt xtþ1 ; ytþ1 =Dt xt ; yt x ;y x ;y =D This can be written as: " #1=2 Dt xtþ1 ; ytþ1 Dt ðxt ; yt Þ Dtþ1 xtþ1 ; ytþ1 Dtþ1 xtþ1 ; ytþ1 * tþ1 * * Dt ðxt ; yt Þ Dt ðxt ; yt Þ D ðxtþ1 ; ytþ1 Þ Dtþ1 ðxt ; yt Þ This is same as: (3) Malmquist productivity index IGDR Y t+1 C # (CRS) F (CRS)t $ (VRS) VRS t+1 F’ * (xt+1.yytt+1) D E C (VRS)t Downloaded by Stockholm University Library At 08:34 08 December 2018 (PT) B B’ *(xt ,yt ) A O Figure 1.

The right hand term in the expression above is the geometric mean of two shifts and thus represents TC. The ratio (OD/OF) is Dtþ1(xtþ1,ytþ1) which is efficiency at t þ 1 using technology t þ 1 and the ratio (OA/OB) is Dt(xt,yt), i.e. efficiency at t using technology t. Thus the left hand term in the expression above represents efficiency change, between times t and t þ 1. This captures whether production is shifting closer to or away from the efficiency frontier over time. This term captures diffusion of technology.

Considering VRS technology, efficiency change is further divided as pure TEC and scale efficiency change as under: " # ðODÞ ðOF0 Þ h tþ1 tþ1 tþ1 i ðOD=OFÞ5 5 D VRS x ; y * ½Scale efficiency at t þ 1So also * ðOF0 Þ ðOFÞ " # t t ðOAÞ ðOB0 Þ DT ðOA=OBÞ5 5 * * ½Scale efficiency at t: VRS x :y ðOB0 Þ ðOBÞ ðOD=OFÞ DVRS tþ1 xtþ1 ; ytþ1 * Scale efficiency at t þ 1: ¼ ðOA=OBÞ DVRS t ðxt :yt Þ * Scale efficiency at t: ¼ ðPure technical efficiency changeÞ * ðScale efficiency changeÞ Downloaded by Stockholm University Library At 08:34 08 December 2018 (PT) Thus D Efficiency ¼ ¼ DðPTECÞ * DðSECÞ Thus Malmquist productivity change index ¼ ðPure technical efficiency changeÞ * ðScale efficiency changeÞ * ðTechnology changeÞ DðMPIÞ ¼ DðPTEÞ * DðSEÞ * DðTÞ 3.2 Profile of selected microfinance institutions The selected 21 MFIs are among the top 25 MFIs rated by Credit Rating and Information Services of India Ltd. (Ratings, 2014). Bandhan Financial Services has been excluded from the list as it has started functioning as an SFB in August 2015, i.e. during period under study. The other three MFIs, namely, Ashirwad Microfinance Private Ltd., Cashpor Microcredit and Swadhar Finserve Pvt. Ltd, are excluded due to non-availability of data. The sample comprises eight MFIs, namely, Disha, Equitas, ESAF, Janalaxmi, Rashtriya Gramin Vikas Nidhi (RGVN), Suryodaya, Ujjivan and Utkarsha, which have been granted “in principle” license by the RBI to operate as SFB in 2015. These MFIs except Janalaxmi Financial Services have started working as banks since 2017. In addition, three MFIs, namely, Bharat Financial Inclusion, Satin and Grama Vidiyal, are already listed. Thus these 11 MFIs have been classified as “for-profit” as their profit motive is clear. The other ten MFIs are not listed and are serving the poor through group or individual lending. These are classified as “not-for-profit”. The sample is representative of microfinance industry in India as its market share (measured by total size of loan portfolio) is estimated to be 80 per cent as on Sept 2013. By and large, the selected MFIs are owned by private individuals or corporates including Foreign Institutional Investors (FIIs) or Non Resident Indians (NRIs). Only 5 out of 21, namely Bharat Financial Inclusion, Grama Vidiyal, RGVN, Satin and Ujjivan are public limited companies and are listed. Selected MFIs are dependent on banks and Non Banking Financial Companies (NBFCs) for funding. In addition, portfolio securitization and Non-Convertible Debentures are the major sources of funding. It is noteworthy that only one MFI, namely Kshetra, (Shri Kshetra Dhramasthala Rural Development Trust) is a charitable trust which, in addition to receiving funding from banks, attracts grants/donations to a small extent. Only three MFIs in the sample, namely, Bharat Financial Inclusion, Janalaxmi Financial Services and Ujjivan Financial Services, have national presence whereas all others are Malmquist productivity index Downloaded by Stockholm University Library At 08:34 08 December 2018 (PT) IGDR regional in character and are expanding their presence in neighboring states. Average loan size of the selected MFIs in 2016 varies between Rs 7,645 and Rs 23,773 (Appendix). 3.3 Selection of inputs and outputs The present study considers inputs as capital and borrowings whereas outputs as outstanding gross loan portfolio and profit. The basic objective of MFIs is to increase access for microcredits to the poor and at the same time ensure sustainability (Gutiérrez-Nieto et al., 2007). The selection of outputs and inputs is based on these objectives. MFIs are essentially financial intermediaries with resources i.e. capital and liabilities to grant loans and generate profit in the process. As MFIs in India are not allowed to accept deposits, they are obtaining short term and long term borrowings, in addition to capital. Short term borrowings can be withdrawn by the lender, within a short period and therefore these are not considered as dependable resources for lending. Thus capital and long term borrowings are the dependable resources against which MFIs can lend. The authors have taken these two as inputs. So also, outstanding loan portfolio and the profit generated are taken as outputs. The outputs are indicative of access to microcredit and sustainability. 3.4 Study period By 2010, various irregularities had occurred in microfinance industry which caused the repayment crisis in Andhra Pradesh. The state government had intervened and the Andhra Pradesh Micro Finance Institution Ordinance 2010 was promulgated, which had put several restrictions on MFIs. It has made the registration compulsory, put a ceiling on interest rates and imposed penalties for coercion in recovery. This was a regulatory shock and the crisis had spread all across microfinance industry in the country. Thereafter, Micro Finance Network (MFIN) was established as self-regulatory organization of MFIs which was recognized by RBI. MFIN came out with first code of conduct for MFIs in 2011. By 2012, microfinance industry had recovered from the crisis. The change in productivity of MFIs is studied for 2012-2016, taking 2012 as a base year. During this period, the microfinance industry had grown very fast, roughly at rate of 40 per cent per annum. This was due to clarity in regulations which proved to be a confidence building measure. MFI industry attracted funds through equity, loans from banks and NBFCs and also through securitization of portfolio and non-convertible debentures. The industry adopted good governance practices, information and communication technology and had scaled up operations. There was another shock for the microfinance industry during later part of 2016 when demonetization was announced, impact of which will appear after 2016 only. There was no shock or aberration other than regulatory developments. As such the study period is important from the point of view of growth, sustainability and development of policy implications for regulating microfinance industry. 4. Findings and discussions A Malmquist productivity index greater than unity reflects the improvement in productivity over a period of time and an index less than unity reflects decline in productivity. Likewise improvement or deterioration in any of the components (Pure Technical Efficiency, Scale Efficiency, Technology and TFP) of Malmquist index is indicated by the values of the respective components relative to unity where, value greater than one shows improvement and that less than one shows deterioration. Downloaded by Stockholm University Library At 08:34 08 December 2018 (PT) TFP change (Tfpc) is an outcome (product) of three factors namely pure TEC (ptech), scale efficiency change (sech) and technology change (techch). The technology change is associated with best practice and is therefore related to industry. Pure technical efficiency represents catching up by the firm with the best practice. This is done through enhancing efficiency through improvement in internal processes and systems. Scale efficiency is the efficiency related to economies of scale. The details of change in efficiency components during 2012-16 for each MFI are given in Table II. Table II shows that TFP of MFIs has gone up by 19.9 per cent (mean value) during the period 2012 to 2016. However efficiency of technology has improved by 12.8 per cent, pure technical efficiency by 2.5 per cent and scale efficiency by 3.7 per cent. During the period under study, highest improvement in TFP was registered by MFI Grama Vidiyal (179 per cent), followed by Arohan (96.6 per cent). At the bottom of the list are MFIs Kshetra and SMILE, with decline in TFP by 29 per cent and 22.5 per cent respectively. Highest improvement in technology was showed by MFI, SV Credit lines (33.4 per cent), followed by Bharat Financial Inclusion (29.0 per cent). However, MFI SMILE has recorded maximum deterioration in technology (18.7 per cent) followed by Kshetra (7.8 per cent). The MFI Grama Vidiyal recorded highest improvement in pure technical efficiency (116.9 per cent), followed by Satin (46.5 per cent). However, MFI Kshetra showed largest deterioration in pure technical efficiency of 22.8 per cent followed by Annapurna (13.4 per cent).

Malmquist index summary of MFI’s means Downloaded by Stockholm University Library At 08:34 08 December 2018 (PT) IGDR In respect of scale efficiency, MFI Arohan has topped the list with 86.8 per cent improvement, followed by Bharat Financial Inclusion (19.9 per cent). However, there was maximum decline in scale efficiency in respect of MFI Janalaxmi (24.9 per cent), followed by Disha (14 per cent). The year-wise summary of annual mean of different components of efficiency, for the period under study, is given in Table III. During the year 2012-13, technology change (which is an indicator of industry best practices) is up by 31.3 per cent, scale efficiency is up by 27 per cent and there is 23.7 per cent improvement in TFP. After the crisis of 2010, microfinance industry started recovering in this year i.e. 2012-13. In the following year, 2013-14, there is very high improvement (65.5 per cent) in pure technical efficiency which is an indicator of “catching up” factor. This indicates that MFIs largely followed industry best practices in this year. During this year, improvement in TFP of MFIs under study is very high (74.3 per cent). In the subsequent year 2014-15, TFP has drastically deteriorated by 78.3 per cent. Technology change is marginally down by 0.6 per cent and scale efficiency is up by 2.8 per cent, however “catch up” factor i.e. pure TEC is down by 76.6 per cent. In 2015-16, technology change is up by 7.1 per cent, however, scale efficiency is down by 13.5 per cent; resulting in marginal improvement of 3.8 per cent in TFP. The discussion above highlights year-on-year performance under each component whereas Figure 2 highlights the change in productivity components with reference to unity. 4.1 Identifying factors affecting productivity The productivity of MFIs was analyzed in the context of the nature of MFIs (profit versus nonprofit), geographical reach, market share and business model. To examine whether market share of MFI affects productivity, we have considered percentage of loan portfolio of each MFI to total loan portfolio of the sample for the years 2012 and 2016. It is observed that market share of “for-profit” MFIs, which was 40.46 per cent in 2012, has increased to 77.14 per cent in 2016, and correspondingly, market share of “not-for-profit” MFIs has declined from 59.54 per cent in 2012 to 22.86 per cent in 2016. Table IV gives firm-wise changes in pure efficiency, scale efficiency, efficiency change, technology efficiency and TFP. In addition, mean values (geometric mean) of the component-wise indices for each category of MFIs are given. It is observed from Table IV that in “for-profit” category, two MFIs namely RGVN and Janalakshmi are lowest in productivity change and their productivity has declined by 11.15 per cent and 12.1 per cent respectively. RGVN is operating in north eastern states of India Table III.

Category wise component indices Downloaded by Stockholm University Library At 08:34 08 December 2018 (PT) IGDR where there is huge infrastructure deficit. Hence the cost of operations for RGVN is comparatively high which has adversely affected its performance. The MFI Janalakshmi has undertaken very rapid expansion geographically across the country and in terms of number of clients and loan portfolio. It was operating in 13 states of India in 2012 and has expanded in eight more states during the period 2012-16. In all, it is operating in 21 states of the country and is national in character. Its customer base increased from 1.2 million in 2012 to 4.6 million in 2016 and its loan portfolio has increased from Rs 23,830m in 2012 to Rs 115,260m in 2016. The MFI has developed large infrastructure with 9,669 branches and 87,402 employees. It has developed and implemented customer centric business model and has invested in technology. In the process, it has achieved very high (21.5 per cent) improvement in technology but has lost on all other components of productivity. The rapid expansion before consolidating had adversely impacted its productivity. This could have been avoided if the expansion had been gradual. Table IV reveals that “for-profit” MFIs are performing better in terms of efficiency change, technology change and TFP change as shown in Figure 3. In “not-for-profit” category, there are two MFIs, namely, Kshetra and SMILE, with deterioration in productivity. Keshtra is a temple trust operating not only on commercial principles but also has undertaken several social activities such as health care, women empowerment and education. In addition to financing the poor and small farmers the trust is engaged in agriculture extension, development of self-help groups and employment generation programs. SMILE has very low profitability with average earning per share of Rs 1.94 during 2012-16 for book value per share of Rs 53.85. Its operations are mostly concentrated in Tamil Nadu, though it has some presence in Puducherry and in few districts of Kerala. The average loan size (2016) of SMILE microfinance is 40 per cent below industry level. It is focusing on financing the poorer amongst the poor and its geographical base is narrow. As their clientele is poorer section of the poor, spreading geographically and leveraging technology (as done by Satin) would have increased their client base and hence improved their productivity. Four MFIs namely Janalakshmi (þ10.94 per cent), Satin (þ9.42 per cent), Grameen (þ5.42 per cent) and Kshetra (46.24 per cent) have shown significant (more than 5 per cent) changes in relative sample share. (Figures in bracket show percentage change over from 2012 to 2016). Both MFIs Janalakshmi and Satin have undergone significant change in size. However the productivity of former has deteriorated whereas that of latter has shown significant improvement (Table IV). This is mainly because MFI Janalakshmi has expanded 30.00 Change in efficiency componets 2012-16 (For Profit and Not For Profit MFIs) 26.20 Percentage 25.00 20.00 15.70 15.00 10.00 5.00 Figure 3.

It has expanded its activities in 33,631 villages with the help of technology and group lending. The MFI Grameen has migrated to Core Banking Solution and has started seven Regional Processing Centers to improve the efficiency of operations. It was awarded Microfinance India award 2015 for good governance, transparency, innovations in process, product and technology, good human resource management and integration of social performance and financial performance. This explains its 15.8 per cent improvement in pure efficiency, 9 per cent improvement in technical efficiency and 29.8 per cent change in TFP being highest in, “not-for-profit” category. The MFI Kshetra has significantly reduced its lending operations and focused on social activities which have resulted in deterioration of its efficiency parameters. The MFIs Grama Vidiyal has shown highest improvement in productivity (179 per cent), in “for-profit” category. Its loan portfolio has grown from Rs 22.02m in 2012 to Rs 13,426.9m in 2016, with recovery rate of 99.97 per cent and membership of 11.17 million. The MFI has managed to keep its infrastructure lean with the help of information technology and is operating through 306 branches. It has been given credit rating A3þ by ICRA in 2015-16. Moreover its industry compliance index score by MFIN is 98.25 per cent. This score incorporates parameters for measuring, managing and integrating responsible business practices. This explains its high improvement in pure efficiency (116.9 per cent) and technology (22.4 per cent). Arohan has shown highest improvement in productivity (96.6 per cent) in “not-for-profit” category. The MFI has rapidly scaled up its operations by aggressively promoting its products Saral, Bazar Plus and Pragati. It has started working as a banking correspondent for IndusInd bank in Assam. Its loan portfolio has grown to Rs5660 million in 2016 from Rs53 million in 2012. This is largely reflected in scale efficiency change (86.8 per cent). Thus it is observed that there are several factors impacting productivity. Moreover it cannot be conclusively inferred that increase in the market share of an MFI will impact its productivity in one way or the other. It is the business model that seems to have a significant impact. 4.2 Mission drift and sustainability Microfinance industry is facing a major challenge of financial viability. There is a concern amongst the stakeholders that in pursuit of sustainability, it is drifting away from its mission of serving the poor and MFIs are moving towards the “better off” section amongst them. We evaluate the sustainability of microfinance industry in India from the point of view of productivity as well as mission drift and examine the trade-off between their conflicting objectives. We use the Malmquist productivity index as a measure of sustainability because it considers profitability and outreach. To examine mission drift, we use the parameters, average loan size, market (Rural/Urban), focus (favorable bias towards women), lending methodology (group or individual) as identified by Mersland and Strøm (2010). Table V illustrates the parameters that indicate a mission drift or mission focus. The extent of focus on mission for each MFI is assessed by comparison with these two extreme positions and is further analyzed in the context of productivity of the respective MFI. Table IV highlights that the market share of MFIs “for-profit” has increased from 40.46 per cent in 2012 to 77.14 per cent in 2016, indicating that there is a shift in the objective, i.e. from serving the “poorest of the poor” to earning a profit for sustainability. The same table Malmquist productivity index Downloaded by Stockholm University Library At 08:34 08 December 2018 (PT) IGDR also indicates that the market share of “not-for-profit” MFIs has reduced from 59.54 per cent in 2012 to 22.86 per cent in 2016, also indicating the mission drift. It is also observed that during the period under study, the average loan size has gone up by 120 per cent for the industry (Micrometer May 2016). Also, the average loan size for the sample has gone up by 92 per cent (Appendix). This shows that Microfinance Industry in India is shifting its client base from poorest section amongst the poor towards those, who are less poor. Most of the MFIs in the sample are having focus on financing women and are following group lending model; but there is a discernible shift from rural to semi urban and urban markets. This clearly indicates that by and large, Microfinance Industry in India is undergoing a mission drift. As per Appendix, the sample of 21 MFIs is classified on the basis of their average loan size vis- a-vis the industry average for the year 2016 as shown in Table VI. There are two MFIs namely Kshetra and SMILE which have controlled mission drift to a large extent but have heavily deteriorated in productivity. The average loan size (2016) of Shri Kshetra Dharamasthala Rural Development Project, (SKDRDP/Kshetra) is 38 per cent below corresponding industry level. It has focused on rural financing to both men and women though group and individual lending. However, its productivity has deteriorated by 29 per cent during 2012-16. SKDRDP is a temple trust and it has undertaken development of Self Help Groups on large scale, which is a non-commercial activity. So also, the average loan size (2016) of SMILE microfinance is 40 per cent below industry level. It has retained its focus on women through group lending, though it is financing both rural and urban poor. However, its productivity has declined during study period by 22.5 per cent. Six MFIs in the sample are able to control mission drift significantly and at the same time have improved productivity during the period under study. Their average loan size (2016) is Sr. No. Mission parameters 1 Ratio of average loan size of MFI to average loan size of industry Market coverage Gender 2 3 Indication of mission drift Indication of mission focus High ratio Low ratio Urban No specific focus on women Individual Rural Women focus Table V.

These are Annapurna (11 per cent, þ21.5 per cent), Arohan (26 per cent, þ96.6 per cent), Equitas (28 per cent, þ4.5 per cent), Fusion (18 per cent, þ2.9 per cent,), Madura (19 per cent, þ10 per cent) and Utkarsha (15 per cent, þ8.3 per cent) (The figures in the bracket refer to sample size with reference to industry average in 2016 and productivity change during 2012-16). Out of these, only Utkarsha is financing through group lending and others are financing individuals and through groups. So also, Arohan and Equitas are financing both men and women whereas others are financing largely women borrowers. As such, for these MFIs, there is no indication of tradeoff between their objectives of sustainability and the mission of serving the poor. However trade-off is discernible in respect of all other MFIs in the sample as discussed below in detail. The MFIs Disha and Grama Vidiyal were marginally below industry level in sample size by 6 per cent and 8 per cent respectively. The productivity of Disha increased marginally by 2.1 per cent whereas Grama Vidiyal has shown highest growth in productivity (179.2 per cent) during the period under study. Thus it can be concluded that in case of majority of MFIs, focus on mission corresponds to lower productivity and vice versa. This shows existence of tradeoff between profitability and mission focus in microfinance industry in India. Out of ten MFIs discussed above, three of them, namely, Disha, Equitas and Utkarsha, have been granted “in principle” license by RBI for working as SFB. Out of these prospective SFBs, Disha has shown marginal increase in productivity and marginal reduction in sample size as compared to the industry average. The other two, Equitas and Utkarsha have shown significant restraint on mission drift with simultaneous improvement in productivity. The sample under study contains six MFIs namely Bharat Financial Inclusion (59 per cent), Satin (76 per cent), RGVN (11.1 per cent), Suryodaya (31 per cent), SV Creditline (33.4 per cent), and Ujjivan (18 per cent) having average loan size at par with industry average (i.e. within range of –5 per cent to þ5 per cent) (The figures in bracket represent percentage change in productivity). These MFIs have achieved significant improvement in productivity, with the exception of RGVN. It has focused on the North Eastern Region of the country which has large infrastructure deficit. This is reflected in decline in its productivity. Out of these, three MFIs namely, RGVN, Suryodaya and Ujjivan have been granted “in principle” license by RBI for working as SFB. The remaining five MFIs namely BSS (þ29 per cent, þ10.6 per cent), ESAF (20 per cent, þ17.9 per cent), Grameen (27 per cent, þ29.8 per cent), Janalakshmi (43 per cent, 12.1 per cent) and Sonata (þ6 per cent, þ22.4 per cent) have average loan size above industry average (The figures in the bracket refer to sample size with reference to industry average in 2016 and productivity change during 2012-16). All these MFIs have shown high rise in productivity (with the exception of Janalakshmi) and also high mission drift as measured by large sample size compared to industry average. However ESAF and Grameen have been largely having rural market with a focus on women borrowers financed through group lending. The MFI Janalakshmi is having largest mission drift indicated by highest average loan size, and urban clientele. There is no indication of gender bias favoring women. They finance both individuals and groups. It is the second largest MFI in the sample measured by gross loan portfolio and it has scaled up fast during 2015-16 but has lost on productivity by 12.1 per cent during 2012-16. It has been granted “in principle” license by RBI for working as SFB along with ESAF. The Reserve Bank of India has granted “in principle” license to ten MFIs in 2015 for working as SFBs, out of which eight are included in the sample. Out of these two, namely, Malmquist productivity index Downloaded by Stockholm University Library At 08:34 08 December 2018 (PT) IGDR Ujjiavan and Janalakshmi, are national in character. Others are regional in character focused in a particular state and are expanding in adjoining states (Table IV). 4.3 Regulating mission drift As SFBs, these MFIs will be required to compete with the other players namely Regional Rural Banks, Co-operative banks and Commercial banks in public and private sector, in their respective areas. The competitors are lending in priority sector at much lower rate and have taken up group lending, leveraging technology. Thus SFBs will be required to lend at a much lower rate as compared to present rate of 22 per cent to 26 per cent and will have to operate on much lower margins, as compared to present margin of 10 per cent. In April 2015, RBI has prescribed a target of 75 per cent of loan portfolio for priority sector advances for SFBs. Moreover, for NBFC-MFIs, the eligible annual household income is increased from Rs 60,000 to Rs100,000 for semi urban and from Rs 100,000 to Rs 160,000 for urban households. So also, the limit for total indebtedness for individuals is increased from Rs 50,000 to Rs 100,000. There is also a possibility of SFBs focusing on housing loans in urban areas which are categorized as priority sector lending. In view of the strong mission drift observed in microfinance industry in India, the authors are of the opinion that present regulations are inadequate. It is necessary to develop robust regulatory framework for MFIs and SFBs, with the objective of maintaining their sustainability and focus on mission. In the absence of strict compliance to such regulations there is every possibility that SFBs will be losing their present character and will turn out to be replicas of their competitors. 4.3.1 Assessment metrics. The success of any initiative is dependent on clarity of mission, establishment of well thought-out systems, processes and periodical assessment to ensure that a desired level of quality in service or product has been achieved and maintained. To monitor this, in addition to supervision of the process of service-delivery at every stage, an assessment metrics is required. The metrics constructed by the authors, will not only measure performance with respect to each of the indicators that are critical to the success of the initiative, but will also grade MFIs in the context of acceptable performance. We suggest that the performance of MFIs and SFBs be measured with respect to assessment indicators and these may be further graded. The grade so attained will be the yardstick to either reward or to take corrective measures for erring organizations. Strict monitoring of performance and compliance will ensure success of the policy to promote SFBs. Towards this end, the authors have constructed an assessment and grading metrics (Tables VII and VIII) to periodically evaluate the performance of SFBs, grade their performance and also for using it for evaluating the eligibility of MFIs for granting license as SFBs. The evaluation metrics is constructed with an objective of striking a balance between conflicting objectives of sustainability and financing the poor (measured through average loan size vis-a-vis industry loan size). Therefore Tfpc above 1.4 is considered as undesirable as it will imply excessive emphasis on sustainability at the cost of mission focus. Hence maximum 20 marks are prescribed for Tfpc between 1.3 and 1.4 or above. So also, sustainability is of paramount importance for MFIs and hence its deterioration below 20 per cent is discouraged by assigning -20 marks for Tfpc score of 0.8 and below, thereby indicating that excessive focus on mission parameters at the cost of sustainability is also not desirable.

Conclusion and policy implications In India, MFIs are playing an important role in economic development by providing microcredit to the poor. MFIs have the dual objectives of achieving profitability and serving the poorest of poor. Very few studies have been undertaken to measure productivity of MFIs in India and the trade-off between sustainability and the objective of financing the poor. The present study fills this gap and its contributions have several policy implications for stakeholders for large-scale promotion of microfinance program in India. We have measured productivity of 21 MFIs (which constitute 80 per cent gross loan portfolio of microfinance industry as on September 2013) using Malmquist Productivity Index, which is a measure of sustainability. The productivity of MFIs was analyzed in the context of nature of MFIs (profit verses nonprofit), geographical spread, market share and business model. We have analyzed the tradeoff between sustainability and the objective of financing the poor i.e. mission. To evaluate the focus on mission we have used 4 parameters namely, average loan size, market (rural/semi urban, urban), gender (focus on women) and lending methodology (group or individual). Lower the average loan size, more is considered the focus on financing the poorer section of the population. In case of majority of MFIs the average loan size is found to be significantly higher than the industry average. Moreover, there is evidence of increasing shift towards financing in semi urban and urban areas. This is indicative of mission drift in the industry. Using the above mentioned parameters, the authors have developed an assessment and grading metrics that can be used to assess the performance of MFIs and SFBs on the criteria of sustainability and mission focus. The same metrics can also be used to develop a robust framework for regulation of SFBs in addition to the existing tools for assessment such as capital adequacy, asset quality, management capability, earnings, liquidity and sensitivity to various risk factors (CAMELS). The Reserve Bank of India or Micro Finance Institutions Network can also use it to rate MFIs. The rating will be useful to lenders, donors and borrowers. It will also be useful for developing incentive schemes such as soft loans or subsidies for developing infrastructure. The Reserve Bank of India can use it as one of the tools for granting permission to MFIs for accepting deposits from public under section 45 of RBI Act. Table VIII.

It will help organizations to compare their performance with best practices in the industry and to identify the areas for improvement. It can also be used for shortlisting MFIs as prospective SFBs. This measurement can be adopted in other countries too. References Ahmad, U.
