Abstract

This note combines a dynamic industrial organization model, in which an industry is subject to exogenous processes of market-size and collusion structure, with a consumption-based asset pricing model for the shares in the industry’s firms. Three main findings emerge for our model under the assumption of information-efficient asset markets. First, the volatility of a firm’s share price is exclusively driven by the volatility of the industry’s market-size. Second, the volatility of a firm’s price-dividend ratio is exclusively driven by the volatility of the industry’s collusion structure whereby high (resp. low) ratios indicate less (resp. more) collusion. Third, for non-volatile collusion structures the price-dividend ratio is constant across different collusion structures.
