Almost all empirical models of competition in differentiated product markets assume that firms have complete information and set prices to maximize current profits. Building on a small theoretical literature, we develop a dynamic model where each firm has private information about a serially-correlated state variable, such as its marginal cost, and sets its price to signal information to rivals. We find that even limited amounts of private information can raise equilibrium prices significantly, and that failing to account for signaling effects can lead conventional merger simulation calculations to substantially underpredict post-merger price increases. We structurally estimate our model using data from the beer industry and find that our model predicts observed changes in price levels and price dynamics following the 2008 MillerCoors joint venture.
