A MODEL OF RETAIL OUTLET SELECTION FOR BEEF

Multinomial logit models were used to explain consumer outlet selection when buying beef, specifically roasts, steaks, ground beef, and other types of beef. Outlets were grouped into supermarkets, butchers, warehouses, supercenters, and others, and the probability of selecting each outlet type over a range of demographic and other variables was tested. The models were estimated from household data, with 198,682 observations used in the estimation. Empirical results showed that the type of beef purchased and the size of the purchase played an importance role in the choice of outlet. Furthermore, the increase in mobility seen when consumers buy larger unit cuts could not be fully explained by price discounting. Implications for the potential growth of each outlet types are discussed.Consumer/Household Economics, Food Consumption/Nutrition/Food Safety,

DEMAND DRIVERS FOR FRESH-CUT FLOWERS AND THEIR SUBSTITUTES: AN APPLICATION OF HOUSEHOLD EXPENDITURE ALLOCATION MODELS

Flowers are purchased for a variety of reasons ranging from expressions of love or sympathy to satisfying environmental and beautification goals. Unlike many foods where some of the attributes can be quantitatively measured such as grams of fat in meats and milligrams of cholesterol in fluid milk, these aesthetically pleasing products present an array of attributes that are closely tied to the buyers reasons for making the purchase. Clearly the attributes are fundamentally different since the goal associated with the purchase depends on the buyers objectives. This also implies that the demand for such products should be much more closely tied to the characteristics for the buyers and the reasons for buying. Flowers are not absolutely essential for survival and; hence, one may find a given share of the population as non-buyers or infrequent buyers. That is, there is considerable latitude with the decision to purchase or not, and again, this wider range of choices is closely tied to the demographics and occasions or periods. Knowing the latitude with the decision to purchase and the perceptions of the characteristics for products are essential to understanding the demand. Purchasing of fresh-cut flowers, potted plants, and dry/artificial flowers should be substitutable to some degree even though physically they are fundamentally different products. Yet these products have many similar attributes when considering the purpose for use. They can be used to express thanks, reflect emotions, project beauty, and show environmental concerns. Hence, even with the physical differences, consumers may easily change their buying behaviors among these types of flower products. Expenditure patterns are tied to many things, including incomes, purposes, occasions, information and perceptions, and product availability (i.e., outlets). These levels of expenditures depend on market penetration (number of buyers), frequency of transaction among buyers, and prevailing prices. Hence, anything that influences consumer entry into the marketing via more (or fewer) buyers and/or increased frequency of transactions must be measured to have a fuller grasp of the demand for flower products. Understanding demand for flowers is useful to help the flower industry to be proactive in addressing demand issues. Actionable variables such as generic and brand promotion programs, and innovative selling methods are important factors likely to influence the future direction of the industry. Hence, it is important to have a complete definitive understanding of the demand drivers for fresh-cut flowers and their substitutes including the relative importance of entry and transactions. To measure factors influencing the demand for flowers such as prices, seasonality, and demographic variables, the demand for flowers in the different forms was estimated using the Almost Ideal Demand System (AIDS) to examine household behaviors in the U.S. flower industry. The model for fresh-cut, potted plants, and dry/artificial flowers explicitly accounted for differences in outlets, purposes, purchasing occasions, growth, income demographics, and prices. These variables were incorporated into the likelihood specification of the AIDS model, including the weight prices often referred to as the Stone Index. Note that Stone Index was not used, rather the parameters included in the weighting were part of the likelihood specification. The actual estimation was completed using the maximum likelihood function that also accounted for possible correlation in the equation residuals. The actual estimation was completed using the maximum likelihood function that also accounted for possible correlation in the equation residuals. Since flowers were made up of a wide range of varieties, references to quantities purchased had little meaning. The AIDS model was in terms of expenditures and prices and not directly the quantities. Yet an explicit demand function can be derived from the model if one can identify a meaningful quantity measure. Instead of quantities demanded the total transactions on flowers were used as a surrogate for quantities. Hence, demand is in terms of transactions per household with the transaction defined as household buyers (b) times monthly frequency (f) of purchases per household; Then, these transactions were expressed on a per household base. Given the complexity and nonlinear nature of the AIDS model, the full meaning of the coefficients cannot be seen by simply observing the coefficient values. To fully gain insight into what can be learned from the estimates, simulations and sensitivity analyses are needed. That is, using the estimated models show the responses to simulated changes in the model variables. Calculating the demand elasticities for the own prices, cross prices and expenditures can be useful for indicating both the allocations of the budget shares among the three flower types; fresh-cut flowers, potted flowering plants, and dry/artificial flowers. However, the distribution properties for each estimated elasticity depend on the distribution properties of each coefficient and actual variable values in the model. It is extremely difficult to calculate each elasticity distribution because of the nonlinear nature of the AIDS model. A useful approach to get around this problem is a bootstrap resampling approach. An application of the bootstrapping is to resample with replacement and re-estimate the elasticity over and over again and determine the distribution properties from the range of estimates. Each simulation procedure measured demand changes by adjusting one or more variables relative to the mean value of all other variables in the demand model. For illustration purposes, each continuous variable was adjusted from 50 percent of the mean level to 150 percent of the mean using increments of 10 percent. Once demand models are known their use can be extended beyond identifying what causes demand changes. They can be useful for making longer term projections and/or forecasts. In other to make projections, both the time span and some expectation about changes in each demand variable must be made. In many circumstances it is nearly impossible to know what future values of specific demand variables will be. Whereas, some variables such as the number of households and income growth can be approximated with some degree of confidence. Furthermore, temporal demand changes were captured with the proxy measure using the time variables where the time represents existing periods and can be extended out to future months. Hence, simply changing the time variables for those future periods is straight forward. Using this time line and placing a set of growth assumptions on total expenditures provide one mechanism for projecting into future periods. These are projections instead of forecast since the projections are based on a set of assumed conditions such as absolute and relative prices, outlet selection, and purpose. Even with these conditions, the projections provide considerable insight into the underlying forces embedded in the AIDS model parameters. As a result, a fresh-cut share as gift-giving was higher relative to that for self-use, while potted shares and dry/artificial shares were slightly higher for self-uses compared to gifts-giving. Monthly shares and expenditures on fresh-cut flowers and dry/artificial flowers from florists were higher than through supermarkets, while shares and expenditures on potted flowering plants from supermarkets were higher than through florists. From the projections, the fresh-cut flower industry would benefit from an overall growth in consumer spending on flower products, while both the potted flower industry and the dry/artificial flower industry lost their shares as total incomes increased for the long-run period. Demand system models provided a picture of the consumer side of the market and attempted to provide the empirical insight into what drive changes in the purchasing behavior. Demand can be assumed completely exogenous to an industry and the industry just accepts the pattern of change. The AIDS model as suggested in this research provides insight into where changes could occur and what the relative category position would appear to be in the absence of any stimulations or adjustment within the flower industry. Yet the same pattern may point to areas needing attention by various sectors within the flower industry. For example, how much gain could be realized by changing the fall drop in seasonal patterns? Who should be targeted? What is the potential gain from price competitiveness versus specific demand enhancement programs? Surprising there are few if any definitive analyses of the broad demand for flowers and this analysis should give the industry a better perspective on the demand for fresh-cut flowers relative to the other goods.Demand and Price Analysis,

Segmentation of Retail Food Store Formats in Qingdao, China

This study empirically estimates a multivariate binary choice model for four categories of food shopping store formats. The results indicate that in the Qingdao market, traditional counter parts such as wet markets and small grocery stores have been dominated by supermarkets and hypermarkets. At the same time, the rapid growth of hypermarkets in Qingdao is significantly challenging current supermarkets in this city, but they do not compete extensively with wet markets and small grocery stores. Further development of various categories of the food shopping store format is linked to store owned characteristics, potential interrelations among existing retail formats, as well as consumers' demographics and shopping habits.Food retail store format, consumer choice, multivariate probit model, China, Agribusiness,

Levy distribution and long correlation times in supermarket sales

Sales data in a commodity market (supermarket sales to consumers) has been analysed by studying the fluctuation spectrum and noise correlations. Three related products (ketchup, mayonnaise and curry sauce) have been analysed. Most noise in sales is caused by promotions, but here we focus on the fluctuations in baseline sales. These characterise the dynamics of the market. Four hitherto unnoticed effects have been found that are difficult to explain from simple econometric models. These effects are: (1) the noise level in baseline sales is much higher than can be expected for uncorrelated sales events; (2) weekly baseline sales differences are distributed according to a broad non-Gaussian function with fat tails; (3) these fluctuations follow a Levy distribution of exponent alpha = 1.4, similar to financial exchange markets and in stock markets; and (4) this noise is correlated over a period of 10 to 11 weeks, or shows an apparent power law spectrum. The similarity to stock markets suggests that models developed to describe these markets may be applied to describe the collective behaviour of consumers.Comment: 19 pages, 7 figures, accepted for publication in Physica

An empirical research of the factors determining customer behaviour in food retail stores

For years the Institute of Marketing at Szent István University has been conducting research in customer and consumer behaviour. This research project focuses on which food shops retail customers choose when it comes to traditional food. This paper briefly summarizes qualitative findings and offers a preliminary analysis of the project’s quantitative stage. Using six focus groups, the qualitative phase tried to identify factors that impact on how food retail shops were chosen. The goal was to pinpoint individual steps in the decision-making process. Shops selected for study were: hypermarkets, supermarkets, discount stores, small shops, markets, specialised stores and cash & carry stores. Following this, using data from the qualitative results, a national representative survey was conducted. The survey used a standardised questionnaire with 1,019 subjects. The survey concentrated on hypermarket customers, as well as identifying this customer group’s segments, and analysing their decision-making traits.Kelly’s repertory grid technique, Qualitative research, Quantitative research, Monroe & Guiltinan’s store choice model, Donovan & Rossiter’s store atmosphere model, store characteristics, segments of hypermarket patrons., Research Methods/ Statistical Methods,

Beyond promotion-based store switching: Antecedents and patterns of systematic multiple-store shopping (revised version).

In this paper, we demonstrate both theoretically and empirically that single-purpose multiple store shopping is not only driven by opportunistic, promotion-based motivations, but may also result from a longer term planning process based on stable store characteristics. We find that consumers may systematically visit multiple stores to take advantage of two types of store complementarity. In the case of 'fixed cost complementarity', consumers alternate visits to high and low fixed cost stores to balance transportation and holding costs against acquisition costs. 'Category preference complementarity' occurs when different stores offer the best value for different product categories, and may induce consumers to visit these stores together on combined shopping trips. In both cases, multiple store shopping leads to a shift from share-of-customers to share-of-wallet retail competition.Multiple store shopping; Spatial competition; Store choice; Planning; Processes; Characteristics; Complementarity; Cost; Costs; Category; Preference; Value; Product; Shopping trip; Competition; Choice; Patterns;

The Impact of Lighting Type on Consumer Behavior in the Purchase of Healthy Products

This project explored how lighting in the produce section of a supermarket can influence a consumer\u27s decision to purchase healthier options. There is research in this field that examines this idea in restaurants, however, this specific area has not been researched. For this study subjects participated in a pre survey, viewed renderings, and took a post survey all at one predetermined time. The estimated time for the completion of this was about 20 minutes, but this time varied between subjects based on how long they spent taking the surveys and viewing the models. The surveys determined correlation between lighting and consumers preferences and were used in the results section of my thesis
