Agricultural Prices, Selection, and the Evolution of Food Industry AgEcon
Gaigne, Carl; Le Mener, Leo.
In this paper, we set up a simple model that explains the relation between low input price, high exit rates and industrial oncentration. More precisely, we argue that falling input prices force firms with low productivity to exit and induce expansion of more efficient incumbents at the expense of less productive producers. Our model helps reconcile some well‐established empirical results regarding the food processing industry. Indeed, agricultural prices have been declining between the early 1900s until 2006 while, over the same period, concentration and firm productivity have been increasing in the agri‐food industry.

Dynamic Assessment of Oligopoly, Oligopsony Power, and Cost Efficiency using the New Empirical Industrial Organization in the U.S. Beef Packing Industry AgEcon
Ji, In Bae; Chung, Chanjin.
In this paper, the new empirical industrial organization approach with a dynamic model is simultaneously employed to measure the degree of oligopoly, oligopsony power, and cost efficiency in the U.S. beef packing industry. The oligopsony power is estimated with two effects: cash cattle procurement market power and captive supply market power. The model is estimated by the Generalized Method of Moments using monthly data from 1990 to 2006. The empirical results reveal the presence of market power in both the beef retail market and the cattle procurement market in the sample period. The captive supply is a source of oligopsony market power, but the effect is considerably small. The oligopsony market power is greater and less stable than oligopoly market...

Market Power and/or Efficiency: An Application to U.S. Food Processing AgEcon
Lopez, Rigoberto A.; Azzam, Azzeddine M.; Liron-Espana, Carmen.
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, oligopoly-power effects either dominate cost efficiency or reinforce inefficiency, resulting in higher output prices in most industries. The article also provides fresh econometric estimates of oligopoly power and economies of size for the industries in question.

Price and Cost Impacts of Concentration in Food Manufacturing Revisited AgEcon
Lopez, Rigoberto A.; Liron-Espana, Carmen.
This study estimates the elasticities of wholesale food prices, cost efficiency, and market power with respect to industrial concentration in 35 food processing industries, modifying the model of Lopez, Azzam, and Lirón-España (2002). In contrast to the results of their earlier analysis, findings of this study indicate that further increases in concentration would result in significant processing cost savings (and Lerner index increases) in nearly all industries and that output prices would decline in nearly 50% of the industries, although significantly so in only 20% of them. As industrial concentration rises, price declines occur in industries with low levels of concentration while price increases occur in highly concentrated industries.
