Ooi and Loo-Lee Sim Department of Real Estate, National University of Singapore, Singapore Do size and Cineplex matter? 111 Received January 2006 Accepted September 2006 Abstract Purpose – This paper aims to address two questions related to the magnetism or drawing power of suburban malls: first, does physical size matter, and second, what is the externalities effect of housing a Cineplex within a shopping center? Design/methodology/approach – The study was carried out through an extensive survey covering 1,283 shoppers in nine selected suburban shopping centers in Singapore. The effects of physical size and the presence of Cineplex on the magnetism on the selected suburban shopping centers are evaluated using analysis of variance (ANOVA) tests. Their effect on shopping duration and expenditure pattern is also empirically tested using a recursive simultaneous equations model. Findings – The survey results affirm that both physical size and the presence of a Cineplex enhance the magnetism of suburban shopping centers. A larger shopping center can facilitate a greater variety of shops and create a more pleasant environment for the shoppers, thus enticing shoppers to visit and stay longer. Cinema patrons prefer to watch movies at Cineplex located in shopping centers. Controlling for the endogenous relationship between duration of visit and amount spent in the shopping center, the regression results show that, while physical size and Cineplex have a positive effect on the duration of visit, they do not necessarily have a direct effect on the amount spent by the patrons in the shopping center. Originality/value – One of the main challenges for mall owners and managers located outside the traditional shopping belt is how to attract shoppers to patronize their malls. While the impact of shopping center size on retail rents and center attractiveness has been addressed in the literature, this paper adds some new insights into the field. The focus on whether the presence of a cinema complex within a shopping center affects its magnetism or not is novel.

Introduction The proliferation of shopping centers outside the traditional shopping belt is happening across the world. The first suburban enclosed shopping center in the USA, called Southdale Mall, was opened near Minneapolis in 1956 (Eppli and Benjamin, 1994). Over the years, shopping centers have grown larger and their one-stop convenience having expanded to include service outlets and entertainment providers. These neighborhood and community shopping centers offer an The authors acknowledge Mark Eppli, the two reviewers and participants at the 2005 American Real Estate Society Meeting in Santa Fe, USA for their comments and feedback on an earlier draft of this paper.

They offer shoppers an attractive sanitized urban experience, but without the associated negatives such as traffic congestion or crime and security issues in traditional shopping districts (Bloch et al., 1994; Roulac, 1994; Erkip, 2003). Suburban shopping centers have indeed become more than a retail place for the local community. In Singapore, they have significantly altered the residents’ lifestyle with their tenant mix of customary retail shops, entertainment outlets, cinemas, public library, and food courts (Ibrahim and Ng, 2002). An important issue face by owners and managers of suburban shopping centers is how to attract shoppers to patronize their malls, especially when they are located outside the primary shopping belt. Convenience, although usually having the largest impact, is by no means the sole determinant of shopping center choices (Severin et al., 2001). While the retail sales are normally related positively to the income level and demographic characteristics of the population in their immediate market, this relationship may be confounded by outshoppers, which are defined as consumers who move across markets (Russel, 1957; Lillis and Hawkins, 1974; Anderson and Kamisky, 1985). Hence, shopping malls that create an appropriate appeal can themselves become destination attractions. The mega-sized Mall of America in Minnnesota, for example, is reported to have drawn one-third of its visitors to travel more than 150 miles to reach the mall (Roulac, 1994). Similarly, the West Edmonton Mall in Alberta was reported to have become Canada’s top tourist attractions with its 800 stores, 110 restaurants, and 400,000 square feet theme park (Bloch et al., 1994). Given that the entertainment motive has become more important in enhancing shoppers’ experience in the recent years, Cineplex are now commonly located within suburban shopping centers. This paper focuses on the magnetism of suburban shopping centers which, because of their location, need to provide a sufficiently attractive shopping experience to offset the distance inertia. In this paper, we gauge the magnetism or drawing power of suburban shopping centers by their ability to first, promote frequent visits from local residents, second, entice “outshoppers” to travel to the mall and finally, encourage both groups to stay longer and spend more during their visit. The paper addresses two questions related to the magnetism of suburban shopping centers: first, does their physical size matter, and second, what is the externalities effect of accommodating a Cineplex within a suburban shopping center? Reilly’s (1931) Law of Retail Gravitation Model and the extension by Huff (1964), which modeled the attractiveness of a shopping center as decreasing with distance and increasing with the size of the shopping center, hypothesize that the magnetism of a suburban shopping center is a function of its physical size[1]. As one of the major tenants in term of space occupied, the Cineplex is expected to contribute to the shopping center by acting as an attractor to increase traffic flow and consequently, generate positive externality for other stores. However, the success of Cineplex in generating positive externality for other stores within the shopping center is still not very clear. This will be related to whether the proprietors of Cineplex deserved to be charged a lower rental rate than other tenants? This paper is the first attempt to examine the payoffs associated with housing a Cineplex within a suburban shopping center. Our study involves a survey of 1,283 shoppers in nine suburban shopping centers in Singapore. The results indicate that physical size does matters to the attractiveness of a suburban shopping center. Whilst mall size, in itself, is ranked 6th in terms of importance, a large-sized shopping center can however facilitate a greater variety of shops and more anchor tenants, which are ranked as important to the shoppers. The benefits of having a cinema as an anchor tenant in suburban shopping centers are also established. In particular, more than 72 percent of those interviewed feel that the presence of a Cineplex would entice them to visit a shopping center more often. Playing the role of any attractor, the Cineplex increases mall traffic and induces more sales for other stores. In the multivariate analysis, we employ a recursive simultaneous equations model to control for the endogenous relationship between duration of visit and amount spent in the shopping center. The estimation results indicate that whilst physical size and Cineplex have a positive effect on the duration of visit, they only have an indirect effect on the amount spent by the visitors in the shopping center. The rest of this paper is structured as follows. In section II, we review previous studies on the patronage of shopping centers. Section III presents the research plan and introduces our measurement of the magnetism of shopping centers. Section IV describes the survey sample. This is followed by a discussion on the size effect in section V and the Cineplex effect in section VI. Section VII presents the results of our simultaneous regression on the impact of both factors on the patrons’ expenditure. Section VIII concludes. II. Literature review What do we know about the success factors of shopping centers? The literature has a lot to say about what makes a shopping center attractive to shoppers. Essentially, both spatial and non-spatial factors are important. A number of studies have examined their influence as determinants of shopping center rent (Sirmans and Guidry, 1993; Gatzlaff et al., 1994; Hardin and Wolverton, 2000). Biba et al. (2006) brings additional insights into the factors affecting customers’ choice for a shopping centre. With respect to location, the two most commonly noted determinants of retail patronage are accessibility and visibility (Simmons, 1992; Ownbey et al., 1994; Forgey et al., 1995). Size and quality of facilities are also relevant to retail patronage to the extent that unfavorable design characteristics may negate the attractions of an accessible and visible site (Brown, 1999). The gravity and potential models have traditionally been used for defining trading areas surrounding major cities. They prescribe that shoppers choose which centers to patronize by balancing between the utility (proxied by the size of the center) and the cost (proxied by distance) of the center to the shopper. With the growth of the regional shopping center, these “laws” have been utilized to predict market boundaries between competing retail facilities within metropolitan areas (Bucklin, 1971). More recently, Eppli and Shilling (1996) employ a retail gravity model to test the importance of retail agglomeration and proximity to competition. They estimate aggregate retail sales (Rij) in retail market i for center j as: Do size and Cineplex matter? 113 JPIF 25,2 Ri;j ¼ Y i * M aj Dgi;j m X M ak k¼j 114 ! Dbi;k where Mj is the size (in square feet of the jth shopping center, Dij is the distance from the ith consumer to the jth shopping center, Mk is the size of the kth shopping center, Dik is the distance from the ith consumer to the kth shopping center, Yi is total retail expenditures in the trade area, and a, b and g are friction parameters (a low value for a indicates that shopping center size is of little importance and low values for b and g means that distance is not inhibiting when selecting a shopping center. Using actual retail sales at 38 regional shopping centers, the authors find that the retail sales are largely determined by center size, and to a lesser extent, by proximity to competition. They find that a decrease in competitive shopping center size of 20 percent increase center J sales by 30 percent to 40 percent. Conversely, a 20 percent increase in the size of competitive shopping center reduces center J sales by 16 percent to 21 percent. In a recent study on Quebec City, Canada, Des Rosiers et al. (2005) developed two space-related indices to measure regional and super-regional shopping centers’ economic potential and centre attraction. Recent studies have shown that enhancement of shopping experiences through the employment of exciting trade types and activities can serve as a better magnetic attraction to shoppers. Non-spatial factors such as retail image and tenant mix are equally critical in enhancing shopping center patronage[2]. Generally, shopping center owners expend resources to achieve a right image to draw shoppers (Mejia and Benjamin, 2002). Similarly, retail mix, which is defined as the combination of stores occupying a shopping center, affects its overall image, patronage and rentals (Kirkup and Rafiq, 1994; Gerbich, 1998). The empirical evidence has shown that the drawing power of a shopping center can be increased by clustering together a large number of similar stores because of agglomeration benefits (Hotelling, 1929; Miceli et al., 1998). Tenant placement within a shopping center is also important to extract maximum rental (Brueckner, 1993). Nelson (1958) and more recently, Eppli and Shilling (1993) attempted to measure the degree of spillover shopping, or “retail compatibility” across different types of non-anchor stores. Based on a sample of stores in 54 shopping centers in the USA, Eppli and Shilling (1993) estimate the degree of retail compatibility (as measured by percentage of customer interchange) as follows: highly compatible (. 30 percent), moderately compatible (10-30 percent), slightly compatible (5-10 percent), incompatible (0 percent) and deleterious (, 0 percent). Anchor tenants also serve as a major drawing power to a retail mall. According to Miceli et al. (1998), developers should be interested not just in an individual store’s profits, but also in the “traffic” it generates, since more traffic will produce larger spillover benefits (and hence profits) for other types of stores. Hence, shopping centers usually have one or more department stores, which are typically charged lower rents, to generate demand for smaller retailers and to insure the success of the shopping centers (Nevin and Houston, 1980; Eppli and Shilling, 1993; Pashigian and Gould, 1998; Konishi and Sandfort, 2003). In his seminal paper, Brueckner (1993) models the rent differential between stores on the basis that tenants differ in their external generating abilities. Ingene and Ghosh (1990) further suggest that demand externalities flow only in one direction from anchor tenants to non-anchor tenants. Roulac (1994), however, note the demise of the competitive strength of traditional department stores as well as the disinclination of new anchor merchandisers to locate in shopping centers. Gatzlaff et al. (1994) tried to quantify the impact of a loss of anchor tenant on the rental rates of 36 neighborhood and community shopping centers located across Florida and Georgia. They find that a shopping center’s aggregate rental would reduce by approximately 25 percent due to the loss of an anchor tenant. An implication of this development is that shopping center owners need to be more selective as to which tenants should anchor their shopping center to maximize revenue and minimize attrition rate. III. Research methodology Before we examine the influence of mall size and Cineplex, the performance of the shopping malls need to be defined first. There are numerous ways in which a shopping center’s performance can be benchmarked – the most direct way would, of course, be to gauge its profitability through its rental revenue or total receipts from retail sales. The Urban Land Institute (ULI) and the International Council of Shopping Centers (ICSC), for example, measure shopping center performance in terms of non-anchor retail sales per square foot[3]. However, due to confidentiality, we are unable to obtain the relevant financial data for the selected shopping centers. Other possible non-monetary performance measures for shopping centers are traffic count, shoppers and tenants’ satisfaction survey, occupancy and turnover rate. For the purpose of this study, we gauge the shopping centers’ performance by their magnetism, which is defined as the ability to attract and retain shoppers. Like the gravitational pull of a magnet, the attractiveness of a shopping center is measured by its ability to first, pull shoppers toward the mall and second, to entice them to stay longer and hopefully, spend more in the shopping center. An extensive survey was conducted at selected suburban shopping centers in Singapore over two weeks, between mid to end September 2003. Nine suburban retail malls were selected for the study, out of which three are located each in the North, East and West regions of Singapore. The location of the selected shopping centers is marked in the map presented in Figure 1 together with the location of Orchard Road, which is the prime shopping belt in Singapore. Easch shopping center is supported by a specific public housing estate with no competition in the form of other malls within the nearby area. The exception being Tampines Mall (29,233 m2) and Century Square (19,517 m2), which are located adjacent to each other in the same housing estate. For the purpose of this study, we have aggregated their details and presented them as though they are one shopping center. Acting as a focal point for the local community, the suburban shopping centers are more like the community shopping centers in the USA. However, these shopping centers have greater potential to attract residents from outside their immediate catchments because they are within easy reach by public transport as they are situated next to a subway (MRT) station and within walking distance from a major bus interchange. Basic details of the sampled shopping centers are provided in Table I. Do size and Cineplex matter? 115 JPIF 25,2 116 Figure 1.

Details of sampled suburban malls JPIF 25,2 118 The average age of the nine suburban shopping centers in our sample is eight years. The newest shopping center is four years old, whilst the oldest shopping center was completed some 13 years ago. Most of the shopping centers are at or close to full occupancy. All have food court and supermarkets. Eight of the shopping centers have department store as anchor tenants. Five of the shopping centers have a branch of the national library and only one mall (Compass Point) does not have a Cineplex. The average size of the shopping malls is 24,855 m2, ranging from 14,864 m2 to 48,750 m2[4]. The number of shops in the shopping malls varies from 93 to 270, averaging 150 retailers in each shopping center. The average space allocated to each retailer range from 133 sq m to 227 m2[5], which is comparable to the average size of retail outlets in New Zealand’s community shopping centers (Gerbich, 1998). On a per m2 basis, the mean net retail space provided is 0.192 m2 for each resident in the immediate housing estate. Not surprisingly, the size of the suburban shopping centers is positively related to the population of the immediate housing estate. For example, the three largest suburban shopping centers, namely Tampines Mall/Century Square (48,750 m2), Causeway Point (39,662 m2) and Jurong Point (37,904 m2) are located in the three most populated public housing estates in Singapore, namely Tampines (216,100 residents), Woodlands (199,100 residents) and Jurong West (211,000 residents). Conversely, Sun Plaza, which has only 14,864 m2 of retail space, supports 58,700 residents in the Sembawang housing estate. Following the retail gravity models, we hypothesize that the magnetism of a suburban shopping center increases with the size of the mall. Similarly, the presence of a Cineplex would enhance the magnetism of a suburban shopping center. The relationships are tested in two stages. First, we examine the effects of physical size and the presence of Cineplex on the magnetism of the selected suburban shopping centers from the survey results. Second, we empirically test their effect on shopping duration and expenditure pattern using multivariate regression models. In order to control for the endogenous relationship between duration of visit and amount spent in the shopping center, a recursive simultaneous equations model is employed as follows: EXPENDITURE ¼ f ðSIZE; MOVIE; DURATIONÞ; ð1Þ DURATION ¼ f ðSIZE; MOVIE; TRAVELÞ ð2Þ where EXPENDITURE is the dollar amount spent on each visit to the shopping center, DURATION is the time spent in the shopping center, SIZE is the size of the shopping mall, MOVIE is a binary variable indicating whether the main purpose of visiting the shopping center is watching a movie, and TRAVEL is the time taken to reach the shopping center. We also control for the characteristics of the respondents (age and gender), the day of interview (weekend or weekdays), whether the main reason for visiting the mall is shopping, whether they are visiting alone or accompanied by family, relatives or friends and how often they shop and watch movies. These factors have been found in previous studies to have a significant influence on shoppers’ spending patterns. The estimator employed is the full information maximum likelihood. Typical of models involving expenditure, which are usually censored, equation (1) is estimated using the “tobit” model. Two fit measures, namely R2ANOVA and R2DECOMPOSITION , are generated using the full sample of observations. The first fit measure takes the variance of the estimated conditional mean divided by the variance of the observed variable. The second measure takes the variance of the conditional mean function around the overall mean of the data in the numerator, whilst the denominator contains the sum of the numerator and a residual variance, the true value minus the conditional mean function (Greene, 2002)[6]. Do size and Cineplex matter? 119 IV. Description of survey sample Mall visitors and cinema patrons were randomly intercepted while they were inside the shopping centers and invited to participate in the survey. To insure that the survey results are not concentrated on specific group of shoppers based on the timing of their visits, the interviews were spread out over different days of the week. In total, 1,283 shoppers obliged to our request to be interviewed. The survey sample is composed of 42 percent of interviews conducted over the weekends and 58 percent during weekdays. The gender of the respondents is also equally distributed with 46 percent of the respondents being males and 54 percent females. The mall and age distributions of the interviewees are presented in Figures 2 and 3. Approximately 25 percent of the respondents were below 20 years of age. The majority (61 percent) fall between the 20-40 years old age group. Respondents above 40 years old constitute another 14 percent of the survey sample. On the whole, Singaporeans tend to visit shopping center more often – all the interviewees said they visit a shopping center at least once a month. In comparison, Figure 2. Distribution of survey respondents by malls Figure 3. Profile of survey respondents by age JPIF 25,2 120 75 percent of Americans go to a mall at least once a month (Bloch et al., 1994). Figure 4 shows that 63 percent of the respondents visit a shopping center at least once a week, whilst another 21 percent visit a shopping center once a fortnight. With respect to the mode of transport, the majority of those interviewed (63 percent) took public transport to visit the shopping centre. A total of 17 percent walk to the shopping center, while the remaining 20 percent relied on private transport. Further analysis on the travel time for various modes of transport reveals that the average travel time is 11.6, 20.1 and 28.4 minutes for those who walk, take their own vehicle and take public transportation, respectively. Consistent with the literature which suggests that most shopping trips are multipurpose (Hanson, 1980; O’Kelly, 1981), most of the respondents indicated more than one activity for making a trip to a shopping center. The three most popular activities are spending time with family and friends (57.7 percent), patronizing the shops (52.7 percent) and having meals (46.0 percent). Table II tabulates the main reasons given for visiting suburban shopping centers. Overall, the results indicate that the suburban malls are more than a place to shop and leisure activities are equally prominent in the visitors’ agenda of activities to do in a shopping center. One in four of those surveyed indicate that they were at the shopping center to catch a movie, whilst another 20.4 percent were at the shopping center to use ancillary services such as using toilet, banking, postal and library facilities provided within the shopping center. As a further indication of the social role of the suburban shopping center in providing leisure and complementary facilities for the community, 88 percent of those surveyed indicate that they are normally accompanied by their friends and family or relatives Figure 4.

Shopping centers serve as an important socializing and meeting place with family and friends. Table III shows the visiting and shopping patterns of those interviewed, sub-categorized by their age, gender and time taken to reach the shopping center. Those in the 20-40 age groups took the longest time to travel to the shopping center. 74.8 percent of the respondents take less than 30 minutes. They are likely to be those who stay in close proximity to the shopping center and therefore, fall within the local retail market boundary of the individual shopping centers. The 25.2 percent who traveled more than 30 minutes to reach the suburban shopping centers be can be defined as “outshoppers”[7]. On average, the respondents spend S$30 on each visit with the actual amount varying significantly across different age group. More specifically, the average amount spent ranges from S$66.50 for those below 20 years old to S$134 a month for those above 40 years old. The result is not surprising since those in the younger age group tend to have less to spend than those in the older age group. However, the data show that teens visit the shopping centers more regularly and they stay longer during each visit. In the past, heavy teen traffic and the many hours spent by teens at shopping centers were viewed unfavorably by the shopping center managers as “inconveniences” that can negatively impact security and operations. However, with the teen population on the rise, retailers have recently seen the benefit to targeting teen shoppers and their large discretionary spending power. In a recent study, Mangleburg et al. (2004) observe that teens who shop with friends (as opposed to shopping alone) are likely to shop more often. They also spend relatively more when shopping with friends than when alone. The average shopper stays in the suburban shopping centers for around 1.86 hours[8]. Table III shows that male patrons tend to stay longer than female patrons in the suburban shopping centers[9]. The differences in the means between the groups are statistically significant. This is a surprising result, which we will come back to later when we discuss the regression results. However, women shoppers tend to visit the shopping center more frequently and spent more on each visit. On average, they spent just below S$100 a month while the male shoppers spent around S$86 a month in suburban shopping malls. It would not be unreasonable to expect suburban malls to attract the patronage of more local shoppers and at higher frequency. Panel C of Table III reveals the duration and frequency of visit as well as the average expenditure of patrons categorized by their travel time. Those who stayed closest to the suburban shopping centers not surprisingly visited the mall more frequently but they also do not stay too long nor spend a lot during their visit. Those who stayed furthest from the mall, on the other hand, do not visit the shopping center as frequently but they do stay longer in the mall in each visit. However, their expenditure of S$80 a month is below average. V. The size effect Table IV presents the magnetism of the nine shopping centers based on the feedback of 1,283 shoppers on how long they take to travel to shopping center and the duration of their visit. Overall, the survey results are consistent with the hypothesis that larger suburban shopping centers are able to attract a higher percentage of “outshoppers” who take a longer time to travel to the shopping centers.

Magnetism of suburban malls JPIF 25,2 124 30 percent of the shoppers in Causeway Point, Junction 8 and Tampines Malls travel more than 30 minutes to visit the shopping centers. Conversely, only less than 14 percent of the shoppers in West Mall traveled more than 30 minutes to reach the shopping center. The same conclusion applies when we examine the travel time of shoppers visiting the shopping center. Results of the analysis of variance (ANOVA) test show that the differences in the travel time between the different shopping centers are statistically significant at 1 percent level. While the whole sample took 23.7 minutes, on average, to reach their destination, the average travel time for the smaller shopping centers is significantly lower. While one may argue that travel time could be linked to accessibility, it should be noted that all the shopping centers are located next to a mass transit station and within walking distance to a major bus interchange. Also consistent with the notion of smaller shopping centers attracting mainly local shoppers, around 38 percent of the respondents state that they walked to Sun Plaza, which is the smallest suburban shopping center in our sample. In contrast, only 14-15 percent of the respondents indicated that they walked to the four largest sampled shopping centers. The last column in Table IV presents the duration of visit for the average shopper in each of the respective shopping centers. The survey results show clearly that larger shopping centers can retain shoppers for a longer duration. For example, the average visiting time for large shopping centers is around 2 hours. On the other hand, shoppers only spent 1.4 to 1.6 hours in West Mall and Sun Plaza, the two smallest shopping centers in our sample. Physical size, however, does not appear to have any significant influence on the frequency of visit, which averaged 3.12 times a month for our whole sample. The results are consistent even after controlling for the gender and age of the respondents. In the survey, we also asked the respondents which shopping mall they patronized frequently and the main reason/s for their choice. The results in Table V show that shoppers are less concern with the cost and ease of finding a parking lot in the shopping center. The branding of suburban shopping center in terms of its prestige and exclusivity is also not important. Convenient location, which is not surprising, had the largest influence on suburban shopping center choices (64.2 percent). Consistent Determining factors Table V.

Having a good tenant mix and a wide selection of shops strongly affects the popularity of a shopping center. Good management and promotions (32.8 percent), having a wide range of complementary services such as banking, library and food court (30.9 percent) and a Cineplex (29.3 percent) are also cited by around one-third of those interviewed. Only one in four respondents indicated that the size of a shopping center is an important factor in determining their choice of shopping center to patronize. Although it is ranked 6th in importance, physical size is a key contributing factor to many desired characteristics of a shopping mall. In particular, a small-sized shopping center may not have enough space to facilitate a wide variety of tenants as well as complementary services expected by shoppers. Even if smaller shopping centers try to squeeze in more tenants, this will be at the expense of making the centers feeling cramped and congested. A large-sized shopping center, on the other hand, is less constrained by space availability to accommodate more tenants to achieve the optimal retail mix and right concept to attract and retain high traffic. An added advantage of being large is the ability to provide wider atriums and circulation networks within the shopping center. These spaces provide a pleasant environment for shoppers, facilitate their social interaction and mingling, as well as provide a venue where promotional events can be held to draw in more visitors. In summary, the survey results support our hypothesis that physical size has a positive impact on the magnetism of a suburban shopping center. Larger shopping centers have a greater ability to firstly, attract those staying outside its captive market to visit it and secondly, hold the visitors longer within the shopping center. Do size and Cineplex matter? 125 VI. The Cineplex effect The average respondent in our survey watches one movie a month (see Figure 5). Only 8 percent indicate that they rarely or do not watch movie in the cinema. The majority watches at least one movie in three months (57 percent). Interestingly, 35 percent of the respondents acknowledged that they are avid movie goers who watch at least one movie every fortnight. Cineplex, like other anchor tenants, serves as an attraction for a suburban shopping center. This notion is supported in our survey with 72.4 percent of the respondents Figure 5. Frequency of watching movie JPIF 25,2 126 indicating that the presence of a Cineplex would entice them to visit the shopping center more often. With respect to the choice of cinema, 65.5 percent of the respondents also indicate that it is important for the cinema to be located close to complementary amenities. More specifically, 71 percent of the respondents also said they prefer to watch movie in a Cineplex housed within a shopping center. In contrast, only 4 percent indicate that they prefer to watch movie in standalone cinema, whilst the balance 25 percent do not have any preference. Table V also shows earlier that the presence of a Cineplex, which was ranked 5th in order of importance, is a primary consideration in the choice of shopping center to visit. Figure 4 also shows that one in four respondents cite watching movie as one of the main reasons for visiting shopping centers. Table VI contrasts the shopping behaviors of cinema patrons clustered by their frequency of watching a movie in the Cineplex. It is clear from the survey that there is a strong positive relationship between the frequency of watching movie and the frequency of visiting a shopping center. For example, those who catch one movie at least once a fortnight visit the shopping centers 3.5 times a month as compared to less than three times for those who watch less than one movie a month. Frequent movie goers also tend to stay longer in a shopping center, although they do not necessarily travel further. In short, accommodating a Cineplex within the shopping mall enhances the shopping center’s magnetism by attracting a specific user group to visit it more frequently and also, entice them to stay longer. One may, however, argue that this group of patrons is passive as they are unlikely to incur expenditure while watching a movie in the Cineplex. Our survey, however, reveals that cinema patrons actually spend more per visit as well. In particular, the most avid cinema fan spends between S$98.61 and S$130.50 a month in a suburban shopping center as compared to less than S$90 a month for those who do not patronize the Cineplex frequently. After deducting the cost of movie tickets and tidbits, each cinema patron on average still spends between S$64 and S$95.70 elsewhere in the shopping center. In addition, 93 percent of the cinema patrons indicate that they have companions when watching a movie. Assuming their companions spend the same amount as the average cinema patron, the spill-over effects to others retailers in the shopping center is further multiplied by the number of accompanying persons. Of relevance are several studies on consumer behavior which suggests that shoppers who shop in groups may cover larger areas of stores, purchase more, and spend more money than when shopping alone (Granbois, 1968; Woodside and Sims, 1976; Sommer et al., 1992; Mangleburg et al., 2004). To further examine the externality benefits of having a Cineplex, we survey the activities of cinema patrons before and after watching a movie. With regard to their time of arrival, the survey shows that around one-third (33.4 percent) would arrive at the cinema just in time for the movie screening. Another 38.7 percent said they would arrive at least 30 minutes before the scheduled screen time, while 17.7 percent would arrive around 60 minutes before the show. A total of 10.2 percent indicated that they would come much earlier than 60 minutes. The survey also asked them what they usually do whilst waiting for the show to begin. Generally, a large number of movie goers patronize the retail outlets and or eat in the food establishments within the suburban shopping center before and after watching a movie show. In particular, the survey shows that their favorite activities before watching the movie are having a meal (43.3 percent), walking around (43.3 percent) and shopping (31.1 percent).

The percentages, based on the categorization by Nelson (1958) and Eppli and Shilling (1993), indicate high compatibility of a Cineplex with food court and other stores in the suburban shopping center. After the movie, 23 percent indicate that they would go back immediately. The others will walk around (39.7 percent), have meals (35.6 percent) and shop (22.8 percent) within the shopping center. 128 VII. Analysis of simultaneous regressions So far, we have examined the magnetism of the suburban shopping centers based on the survey results. We focused primarily on how physical size and the presence of a Cineplex enhance the drawing power and retaining power of the shopping centers. In this part of the study, we extend our study to examine their effect on the dollar amount spent within the suburban shopping centers. We employed a Tobit model embedded in a recursive simultaneous equations model to test the isolating effects of physical size and the presence of a Cineplex. The specification of the regression models are presented earlier in Section III. The definitions and pair-wise correlations of the variables used to test the relationships are provided in Table VII, which reveals several interesting relationships. Specific to our study focus, the expenditure amount spent per visit is influenced largely by the characteristics of the visitors rather than the motive of their visit to the shopping center. While the physical size of a shopping center has a positive influence on how long a patron would stay in the shopping center, the strongest determinant of stay duration is movie watching. The matrix shows that avid movie goers, not surprisingly, tend to be young and single but they usually watch movies with friends. The estimation results of equations (1) and (2) are presented in Table VIII. Model 1, which is presented mainly for comparison purpose, is based on a Tobit regression of a single equation on amount spent per visit (equation (1)). Model 2, which is our focus, is a two-equation model that controls for the simultaneity of duration of visit and the amount spent in the shopping center. The magnitude of the R2ANOVA and R2DECOMPOSITION indicates that around 14.7 per cent of the variations in the patron’s expenditure are explained by the variables in our model. In addition, the diagnostic LM statistic for Cragg’s model shows that the censoring is the appropriate specification for the expenditure model. A simple t-test analysis confirms the exogeneity of y2, namely the time spent by patrons in a shopping center, in Regression 1 of Model 2. Results of Model 1 show that expenditure amount of shopping center patrons is determined primarily by their age, which is highly correlated to their income level. Not surprisingly, those who indicated that their main purpose of visit is shopping tend to spend more. In addition, patrons who stay longer in a shopping center also spend more. While the size of the shopping mall and watching movie per se do not significantly increase the expenditure pattern of the patrons, the results suggest that those who watch movie frequently tend to spend more in shopping centers as well. The estimation results of Model 2 provide more insight into the dynamics of how physical size and the presence of a Cineplex affect the performance of the shopping centers. The first regression shows that once the simultaneity of visit duration is taken into account, mall size and watching movie actually have negative marginal effects on expenditure.

The first model is based on a Tobit regression of a single equation (equation (1)), while the second model is based on two equations to control for the simultaneity of duration of visit and the amount spent in the shopping center. The results of Model 1 are presented for comparison purposes only straightforward because both factors have a positive and significant influence in the second regression. Duration of visit in turn has a positive and significant effect on expenditure in the first regression. Overall, the results show that having a larger shopping center and Cineplex induce shoppers to stay longer but their marginal effect on expenditure pattern is at best indirect. Regression 2 further reveals that patrons tend to stay longer during the weekends and when they are with companions (either family members or friends). In contrast to our earlier observation in Table III, the estimation results indicate that male patrons tend to spend less time in a suburban shopping center than female patrons after taking into account the confounding effects of other variables. Furthermore, those who took a longer time to reach a shopping center tend to spend more time in the mall. Although the correlation matrix suggests that Watching movie is only slightly correlated with Movie fan (0.20), we repeated the recursive estimation by withdrawing Movie fan from equation (1) to check if there may be some multicollinearity between the two variables, thereby causing the sign of the Watching movie in equation (1) to be negative. The estimation results, not reported, show that our earlier findings are robust to the exclusion of the Movie fan variable and hence, not affected by multicollinearity between the two variables. The results are also robust when we substitute the age of respondents with either their marital status or their income level. VIII. Summary and conclusions Two common problems faced by developers, owners and managers of shopping centers located outside the traditional primary shopping area are addressed in this paper: First, does size matters in the success of a suburban shopping center, and second, what is the impact of accommodating a Cineplex within a suburban shopping center. A survey on 1,283 shoppers was carried out in nine selected suburban shopping centers in Singapore. The results indicate that physical size and the presence of a Cineplex do enhance the magnetism of suburban shopping centers. Both factors enhance their ability to attract “outshoppers” and to make the visitors stay longer in the shopping center. Although mall size, in itself, may not be ranked very highly by shoppers when determining shopping center choices, a large shopping center can facilitate a greater variety of shops and a more pleasant environment to lure shoppers and make them stay longer. The survey further shows that cinema patrons prefer to watch movies in Cineplex located in shopping centers and that they generally stay longer in the shopping center as compared to non movie goers. The presence of a Cineplex also has spill-over benefits for other stores within the shopping center. Moreover, having a Cineplex in the suburban shopping center fulfills its secondary role of providing a lifestyle and recreational facilities for the local community. Although the regression results show that Cineplex and physical size does not increase the S$ amount spent in the shopping center, the two factors indirectly affect how long patrons will stay in the shopping center, which in turn is positively related to expenditure level. This paper contributes to the literature by drawing attention to the magnetism of suburban shopping centers. As the trend move towards locating shopping malls outside the prime shopping areas, enticing prospective shoppers to visit these shopping centers becomes a critical survival issue for the owners. Hence, an understanding of the magnetism or drawing power of shopping centers is important to enhance the malls’ performance. The study also provides a richer understanding of the shopping behavior and patronage of cinema patrons. Further insights here would allow the developers and retailers to reach out and market to this segment more effectively. It remains for us to acknowledge that while the conclusions are interesting, the high-density urban fabric of Singapore, and eventually, the shopping and leisure culture that prevails on the island may partly explain the study findings. In particular, it has been noted that Singaporeans as a whole tend to Do size and Cineplex matter? 131 JPIF 25,2 132 frequent shopping center more often that the Americans. Furthermore, there may be a scale effect since Singapore is a small island linked with a comprehensive public transportation system, as compared to say America and UK where the suburbs are further from one another. The question remains whether, and to what extent, the conclusions derived from this study can be extended to other contexts. For comparison purpose, it would be interesting if similar surveys and studies could be carried out in other markets. Notes 1. Although the term “magnetism” may appear to be similar to “attractiveness”, the former terminology is adopted in this study to convey the managers’ active pursuit to first, attract shoppers to the malls and then retaining them in the mall for a longer duration. 2. In their review of the literature, Mejia and Benjamin (2002) suggests that understanding the effect of non-spatial factors is important because: non-spatial factors increase retailer differentiation in competitive retail markets; they promote brand identity as retailers develop alternative non-store retail formats; and they represent a source of shopping center intangible value. 3. In most retail leases, the rental include a fixed rent component as well as an overage rent which is calculated as a percentage of sales after a certain threshold level. Mejia and Benjamin (2002) underline that understanding the creation of shopping center rents starts with understanding the determinants of retail sales. The use of overage rent in retail leases is seen as a landlord-tenant risk sharing tool (Brueckner, 1993; Lee, 1995; Miceli and Sirmans, 1995; Colwell and Munneke, 1998). Pashigian and Gould (1998) and Wheaton (2000) further characterize overage rents as an incentive for landlords to optimize tenant mix. 4. The suburban malls in Singapore are comparatively much smaller than regional malls in the USA, which have a competitive center size of 888,000 square feet (Eppli and Shilling, 1996). 5. Since the space occupied by anchor tenants is generally much larger than other tenants, actual space occupied by non-anchor tenants will be much lower than 133-277 m2. P P 6.

This categorization follows from Mejia and Benjamin (2002) who indicate that the retail market of a mall is traditionally referred to as the area from which a shopping center draws 70 percent-80 percent of its sales. 8. While it is possible that the results may be bias to the extent that those who spend more time at the mall are more likely to be sample (Roy, 1994), the duration of visit are nevertheless consistent with existing evidence. For example, a survey conducted by the International Council of Shopping Centers (ICSC) in 2001 revealed that shoppers would usually stay for an average of 73.4 minutes in malls less than 74,322 m2. Source: www/ icsc.org/about/about.shtml Erkip (2003) also observes that mall visitors in Turkey tend to stay at most one to two hours. 9. Otnes and McGrath (2001) is the first study to focus on men’s shopping experiences in an in-depth manner. They demonstrate how actual male shopping behavior belies three common stereotypes of male shopping behavior: “Grab and Go,” “Whine and Wait,” and “Fear of Feminine”.
