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.

When is Concentration Beneficial? AgEcon
Liron-Espana, Carmen; Lopez, Rigoberto A..
This paper separates market power and efficiency effects of concentration in a sample of 255 U.S. manufacturing industries and computes welfare changes from rises in concentration. The empirical findings reveal that in nearly two-third of the cases, consumers lose as efficiency gains are generally pocketed by the industries. From an aggregate welfare standpoint, concentration is found to be beneficial in nearly 70% of the cases, mostly for low and moderate levels of concentration being particularly against the public interest in highly concentrated markets. Overall, the results support the existing U.S. Federal Trade Commission guidelines for approval of mergers.
