Wal-Mart, Oligopsony Power and Entry: an Analysis of Local Labor Markets AgEcon
Bonanno, Alessandro.
Wal-Mart, the largest retailer worldwide, has been suspected of exercising market power over input providers, both merchandise suppliers and workers. However, in spite of a growing body of literature investigating the beneficial economic impact of the company through its price-lowering effect, research analyzing the company’s economic impact over input suppliers is limited. This paper presents a general framework which can be used to investigate Wal-Mart’s market power over input suppliers, vis-à-vis a variation in input productivity, focusing on homogenous intermediate goods supplied locally. The model is general enough to account for incumbents’ reaction to Wal-Mart’s entry resulting in exit, entry and changes in the production technology. A simplified...

Imperfect competition in the fresh tomato industry AgEcon
Hadj Djelloul, Mohammed; Requillart, Vincent; Simioni, Michel.
In this paper, we analyse the market power of the retail industry in the French tomato market. Following the methods developed in the New Empirical Industrial Organization, we develop a structural model of this industry. The analysis is based on detailed data on final consumption and prices at both shipper and consumer levels for two types of tomatoes in France. The structural model is composed of a system of demand equation and supply equation. Supply equation includes a term that represents the market power of the retail sector. We use different models of demand in order to test the robustness of our results. We show that i) elasticity of demand varies during the year ii) the retail sector exercise only a "moderate" market power iii) the estimated...

STOP OR GO? HOW IS THE UK FOOD INDUSTRY RESPONDING TO FRONT-OF-PACK NUTRITION LABELS? AgEcon
Van Camp, Debra; Souza Monteiro, Diogo M.; Hooker, Neal H..
Food nutrition labels have been used for over a decade to aid consumers in making more informed diet choices and to potentially reduce societal costs from diet-related diseases and health conditions. While there is some evidence of the effectiveness of nutrition labels in changing consumption patterns, the scale of such improvements have been marginal. This has led certain government agencies to consider alternative forms of nutrition information. One such approach is front-of-pack (FOP) nutrition labels which provide simple, easily accessible information on a limited number of key nutrients. The use of FOP labels may facilitate healthier diets by influencing consumer behaviour and by providing an incentive for industry to formulate healthier products....

Empezando a conocer el mercado doméstico: Análisis de la oferta de productos de carne bovina. AgEcon
Lanfranco, Bruno A.; Reyes, Maria L.; Risso, Juan M..
El presente estudio procura conocer mejor la demanda de productos de carne bovina para tres áreas geográficas de Montevideo que representan diferentes niveles socioeconómicos de la población, a través de la oferta observada en los dos principales formatos de comercialización: supermercados y carnicerías. En la zona de mayor nivel socioeconómico (AG1) se comercializa el 21% del volumen total de estos productos mientras que en la de nivel medio (AG2), con mayor concentración poblacional, se comercializa el 47%; el restante 32% se vende en la zona de menor nivel (AG3). Los resultados obtenidos mostraron que a medida que disminuía el nivel socioeconómico de los consumidores aumentaba la demanda por cortes más económicos (aguja, paleta, falda y asado) en...

ESTIMATING THE IMPORTANCE OF SHELF SPACE CONFIGURATION ON RETAILER'S PROFIT AgEcon
Roucan-Kane, Maud; Martens, Bobby J.; Preckel, Paul V..
Retail shelf space allocation remains a central issue in grocery retailing. A literature review produced many studies on retail shelf space allocation, but none which evaluated shelf space allocation using three major factors at once: space, vertical height, and price. In this study, shelf space allocation was modeled from the perspective of a retailer maximizing profit using space, vertical height, and price. Using benchmarking, the results show how shelf configuration affects consumer demand and retailer profit. Parameters for the model were based on experience-based intuition. Although the initial results are not valuable at this point, the method and results create a rationale and motivation to gather primary data. Once primary data is collected, this...

Electronic Commodity Market System for Food Networks AgEcon
Fomina, Julia; Fomin, Eduard.
On the agricultural market, like any other market, there are transaction costs such as “discovering what the relevant prices are, the costs of negotiating and concluding a separate contract for each exchange transaction1”, and others. According to our research the average level of transaction costs in Russia for small and medium-sized enterprises is about 28% of the total cost. If the transaction costs of agricultural market are high, in order to reduce them entrepreneurs can arrange the additional production of goods within the firm, replacing market relationships on the relations within the firm. For example, in Russia, the large grain producers often have their own storage of grain (elevators) and mills, bakeries and even shops, because it is more...

Investigating Thai Shopping Behaviour: Wet-Markets, Supermarkets and Food Quality AgEcon
Gorton, Matthew; Sauer, Johannes; Supatpongkul, Pajaree.
An analysis of primary survey data on Thai shopping behavior seeks to understand the relative satisfaction of consumers with wet markets and supermarkets and identify the factors that affect frequency of visit to, and purchase behavior within, these retail outlets. This is used as a basis for engaging in wider debates on the ‘supermarket revolution’ in Asia. On all salient attributes affecting retail outlet choice, wet markets are perceived, in general, to be inferior to supermarkets. However for fresh produce sales, wet markets retain an advantage. Both socio-economic characteristics and retail outlet attributes are considered as determinants of food shopping behavior. Bootstrapped bivariate ordered probit models identify that those using wet markets more...

Investigating Thai Shopping Behavior: Wet-Markets, Supermarkets and the ‘Big Middle’ AgEcon
Gorton, Matthew; Sauer, Johannes; Supatpongkul, Pajaree.
Drawing on the Big Middle theory of retail evolution, an analysis of primary survey data on Thai shopping behavior seeks to understand the relative satisfaction of consumers with wet markets and supermarkets, identifying the factors that affect frequency of visit to, and purchase behavior within, these retail outlets. This provides the basis for engaging in a wider debate on the possibility of a ‘Global Big Middle’ for food retailing. On all salient attributes affecting retail outlet choice, supermarkets perform better than wet markets. However for fresh produce, wet markets continue to account for the majority of expenditure, albeit to a far lesser extent than in previous studies. A bootstrapped bivariate ordered probit model identifies that supermarkets...

Market Power in UK Food Retailing: Theory and Evidence from Seven Product Groups AgEcon
Lloyd, Tim A.; McCorriston, Steve; Morgan, C. Wyn; Rayner, Anthony J.; Weldegebriel, Habtu T..
Establishing the presence of market power in food chains has become an increasingly pertinent line of enquiry given the trend towards increasing concentration that has been observed in many parts of the world. This paper presents a theoretical model of price transmission in vertically related markets under imperfect competition. The model delivers a quasi-reduced form representation that is empirically tractable using readily available market data to test for the presence of market power. In particular, we show that the hypothesis of perfect competition can be rejected if shocks to the demand and supply function are significant and correctly signed in price transmission equations. Using a cointegrated vector autoregression, we find empirical results that...

Food Access and Food Security – An Empirical Analysis AgEcon
Bonanno, Alessandro; Li, Jing.
This paper analyzes the effect of access to different types of food outlets on households’ food insecurity levels. Two years (2004 and 2005) of Current Population Survey – Food Security Supplement data are matched with MSA-level data on store counts of Wal-Mart Supercenters, small food stores (small grocery stores and convenience stores), medium and large grocery stores, and convenience stores associated with gas stations. Endogeneity of food stores’ location is accounted for to eliminate spurious correlation between households’ food security status and food access. Preliminary results indicate that, before accounting for endogeneity bias, the presence of Wal-Mart supercenters appears to be associated to higher levels of households’ food insecurity, while...

Is Wal-Mart a Monopsony? Evidence from Local Labor Markets AgEcon
Bonanno, Alessandro; Lopez, Rigoberto A..
This paper measures the degree of monopsony power exerted by Wal-Mart over retail workers using a dominant-firm model and data in the 48 contiguous U.S. states for counties where the company operates, presenting for the first time a measure of the company’s anticompetitive behavior. Empirical results show that Wal-Mart’s monopsony power over workers varies significantly across the country, being higher in non-metro and rural counties, particularly in the south. For instance, Wal-Mart’s buying power index in labor markets in rural southern and central states is estimated to be 5% or higher while the impact on northeastern states’ retail wages is negligible.

Competition Effects of Supermarket Services AgEcon
Bonanno, Alessandro; Lopez, Rigoberto A..
This paper investigates the effect of in-store services on retail food prices, supermarket competition, and demand using fluid milk as a case study. It is shown that higher-service supermarkets charge higher milk prices essentially because of an increase in market power due to differentiation of service offering. Results show that different types of services impact milk prices differently, that upscale food-retailers face stronger competition in newer services, and that service competition results in a trade-off for the consumer between the attractiveness of the enhanced retail configuration and the increase in prices.

Two-Part Tariffs versus Linear Pricing Between Manufacturers and Retailers: Empirical Tests on Differentiated Products Markets AgEcon
Bonnet, Céline; Dubois, Pierre; Simioni, Michel.
We present a methodology allowing to introduce manufacturers and retailers vertical contracting in their pricing strategies on a differentiated product market. We consider in particular two types of non linear pricing relationships, one where resale price maintenance is used with two part tariffs contracts and one where no resale price maintenance is allowed in two part tariffs contracts. Our contribution allows to recover price-cost margins from estimates of demand parameters both under linear pricing models and two part tariffs. The methodology allows then to test between different hypothesis on the contracting and pricing relationships between manufacturers and retailers in the supermarket industry using exogenous variables supposed to shift the...

Buyer Market Power and Vertically Differentiated Retailers AgEcon
Wang, Shinn-Shyr; Rojas, Christian; Lavoie, Nathalie.
We consider a model of vertical competition where downstream firms (retailers) purchase an upstream input from a monopolist and are able to differentiate from each other in terms of quality. Our primary focus is to study the effects of introducing a large retailer, such as a Wal-Mart Supercenter, that is able to lower wholesale prices (i.e. buyer market power). We obtain two main results. First, the store with no buyer market power responds to the presence of the large retailer by increasing its quality, a finding that is consistent with recent efforts by traditional retailers to enhance shoppers’ buying experience (i.e. quality). Second, the presence of a large retailer causes consumer welfare to increase. There are, however, two reasons for the increase...

SNAP Efficacy and Food Access – A Nationwide Spatial Analysis AgEcon
Bonanno, Alessandro; Ghosh, Gaurav S..
As the public expenditure for the Supplemental Nutrition Assistance Program (SNAP) - formerly the Food Stamp Program (FSP) - increases, improving the effectiveness of the policy becomes pivotal to limit further surges in public spending. Along with social stigma, transaction costs, associated in part to the accessibility and proximity to food outlets, are the main deterrent to program participation. This study presents an empirical assessment of the relationship between food access and FSP participation among eligible population. The analysis uses county-level data for the continental U.S., distinguished by different stores formats (grocery stores, convenience stores and a non-traditional, low-priced alternative, Wal-Mart Supercenters) accounting for the...

Grocery Retailer Pricing Behavior for California Avocados with Implications for Industry Promotion Strategies AgEcon
Li, Lan; Carman, Hoy F.; Sexton, Richard J..
Rising concentration and consolidation of sales among large supermarket chains in the U.S. and other countries, due in part to a recent wave of mergers in food retailing, have made retailers' role in the food industry a topical issue. Using a unique micro dataset, this paper investigates retailer pricing issues for avocados, a key California specialty commodity, and analyzes the implications of retailer pricing behavior for the effectiveness of avocado industry advertising programs. The methodologies developed and the results achieved in this study should have broad applications across the produce sector, the food industry, and the grocery retail market. We find that retail prices for avocados are highly dispersed both spatially and temporarily. The...

Trust and Control Dynamics in Agrifood Supply Networks: Communication Strategies for Electronic Transaction Environments AgEcon
Fritz, Melanie; Hausen, Tobias.
Agrifood supply networks are dynamic structures where firms regularly face the need to search for new market partners. A decision for a transaction with a new partner requires the existence of appropriate control and safeguard mechanisms as well as trust to overcome perceived risk and uncertainties. Electronic transaction environments offer new potentials for the identification of new transaction partners. However, trust and control need to be communicated appropriately in electronic transaction environments for agrifood supply network scenarios. Problems for appropriate communication are posed by the complex interrelation between trust and control in transaction processes and their dynamically changing importance in a transaction relation. This paper...

Concentration in Hungarian Food Retailing and Supplier-Retailer Relationships AgEcon
Juhasz, Aniko; Stauder, Marta.
The paper is a summary about the Hungarian retail sector based on the results of different research projects completed in the last five years. From all of these studies and of course the wide ranging domestic and international literature we had to conclude that the retailers have become more and more the exclusive owner of the information about the consumers and with this they become the new "captains" of the food chain. Thus we always started our research with gathering information about the situation of the Hungarian retail sector because we believed if we want to help those who try to adapt (the suppliers) then we have to know much more about those who dictate (the retailers). Analysing the concentration in company and not branch level we can say that...
