ECONOMIC EFFECTS OF A BAN AGAINST ANTIMICROBIAL DRUGS USED IN U.S. BEEF PRODUCTION AgEcon
Mathews, Kenneth H., Jr..
Economic effects for three scenarios of antimicrobial drug use in livestock production -- a no-ban scenario and two levels of bans -- are examined through cost minimization and a partial equilibrium analysis. Results indicate that regulating antimicrobial drug use in livestock production would increase per-unit costs of producers previously using drugs and reduce beef supplies in the short run, reducing consumer surplus. Producers not previously using drugs would benefit from short-run price increases.

The Transmission of Price Trends from Consumers to Producers and Tests of Market Power AgEcon
Lkassbi, Driss; West, Gale E.; Clark, J. Stephen.
This study examines the competitiveness of four Canadian agricultural industries (eggs, milk, chicken and turkey) using a general equilibrium farm to retail pricing model developed by Wohlgenant (1989). The model generates retail and farm pricing equations that are estimated using maximum likelihood developed by Johansen (1992). The results indicate that in all cases, long-run constant returns is rejected, indicating market power within the Canadian retail to farm marketing sector. The model also finds more cointegrating vectors than predicted by theory, also inconsistent with competitive markets. Results are based on commercial disappearance as a proxy for consumer demand and therefore confounding between uncompetitive markets and quality differences may...
