Transparency and Competition
Abstract
This paper examines the effects of search costs on prices in a Bertrand duopoly. It is shown that if the search cost is lowered, the expected price goes down in a single play of the stage game. However, if the game is repeated it may be easier to sustain collusion the lower the search cost. In other words increased transparency may facilitate collusion even if the sellers' information is unaffected. A transitory improvement of price transparency unambiguously leads to lower prices. Hence, the model provides theoretical support for the price publication practices of consumers' councils.Download Info
