Abstract

This paper incorporates inventory dynamics into a standard conjectural variations analysis of market power. Using a model which incorporates closed-loop equilibrium strategies, we show that measures of market power that ignore inventory dynamics are biased. We then apply the model to the beef-packing industry using annual data on cattle stocks, slaughter and prices from 1933-1999. Our estimates suggest that static measures overestimate the amount of market power exerted by beef-packing firms.
