An Analysis of Wal-Mart Refrigerated Orange Juice Sales AgEcon
Brown, Mark G..
In this paper, estimates of the impacts of various factors on the refrigerated OJ sales in Wal-Mart (WM) stores are presented. Data on WM stores, as well as grocery stores doing $2 million or greater annual business, across 52 Nielsen city markets (including the remaining U.S.) were studied. Since WM does not have stores in San Diego, this market was omitted. Weekly data for each city from week ending 3/11/06 through 3/01/08 (104 weeks) were included in the analysis. The relationship between WM refrigerated OJ dollar sales per store and 1) WM and $2million store prices, $2 million store promotions, a dummy variable to test whether sales may spike during periods when some consumers receive their paychecks (middle or end of the month), the number of same...

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...

Do prices fall faster when Wal-Mart is around? The effect of competition and reputation on cost pass-through and price adjustment AgEcon
Martens, M. Andrea.
This study analyzes Wal-Mart’s pricing practices and its influence on competitors’ input cost transmission. Previous attempts to analyze Wal-Mart’s pricing strategy in the United States have been limited by the company’s refusal to provide scanner data to third party research firms such as AC Nielsen. This is the first study to observe Wal-Mart’s prices over an extended period of time. Using weekly-store level price data between 2001 and 2006 that government officials collected in 12 Mexican cities, I find that Wal-Mart adjusts its prices 1/3-3 times slower to wholesale price increases than other retailers and responds 5-7 times faster to wholesale price decreases than its competitors. This evidence is robust to the comparison of Wal-Mart to other hypermarkets...

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.

Small Farmers and Big Retail: trade-offs of supplying supermarkets in Nicaragua AgEcon
Michelson, Hope; Reardon, Thomas; Perez, Francisco Jose.
In Nicaragua and elsewhere in Central America, small-scale farmers are weighing the risks of entering into contracts with supermarket chains. We use unique data on negotiated prices from Nicaraguan farm cooperatives supplying supermarkets to study the impact of supply agreements on producers’ mean output prices and price stability. We find that prices paid by the domestic retail chain approximate the traditional market in mean and variance. In contrast, we find that mean prices paid by Wal-mart are significantly lower than the traditional market but that Wal-Mart systematically reduces price volatility compared with the traditional market. We find some evidence, however, that farmers may be paying too much for this contractual insurance against price...

The Impact of Wal-Mart Supercenters on Supermarkets’ Profit Margins AgEcon
Liu, Xiaoou; Lopez, Rigoberto A..
The Impact of Wal-Mart Supercenters on Supermarkets’ Profit Margins. XIAOOU LIU (Email: xiaoou2010@gmail.com, School of Agricultural Economics and Rural Development, Renmin University of China, Beijing, China 100872) RIGOBERTO LOPEZ (Professor and Department Head, Department of Agricultural and Resource Economics, Storrs, CT 06269) This paper quantifies the impact of Wal-Mart Supercenters on supermarkets’ profitability via a two-stage dynamic entry game, using simulated methods of moment and milk scanner data from Dallas/Fort Worth supermarkets. The empirical findings show that the entry of Wal-Mart Supercenters accounts for about an average of 50% decreases in profit margins for incumbent supermarkets. The effect of scale of economies is found to be more...

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...
