This article separates oligopoly-power and cost-efficiency effects of changes in industrial concentration and assesses their impact on output prices in 32 food-processing industries. Empirical results indicate that although concentration induces cost efficiency in one-third of the industries,...

This paper uses Data Envelopment Analysis to measure scale and technical efficiencies of 925 farms in rural Colombia and a Tobit model to identify the effects of land market characteristics on efficiency. Findings indicate that although larger farms are more scale efficient, they are not more...

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...

This article examines the role of imperfect competition in determining total factor productivity growth (TFPG) by bringing together a New Empirical Industrial Organization (NEIO) model and the TFPG model of Nadiri and Mamuneas (1998). Applying the integrated model to 1973-92 data from 29 food...

This paper investigates the impacts of store brands (i.e., private labels) and retail characteristics (scanners, deli, bakery, and pharmacy departments, ATMs, restaurant and store size) on fluid milk prices using 1,740 supermarket-level observations from four cities. Non-parametric results...

This paper assesses the impacts of the Northeast Dairy Compact (NEDC) and retail oligopoly power on fluid milk prices in Boston. Empirical results reveal that price increases due to oligopoly power outweighed those caused by the NEDC by nearly seven times. In fact, markups are estimated at...

We examine the impact of four policy options on consumption of carbonated soft drinks (CSDs) by estimating a random-coefficient discrete-choice model of demand. Policy simulations using demand estimates indicate that the impacts of banning television advertising, limiting container size, and...
