We provide a self-contained, selective overview of the literature on the role of knowledge and beliefs in game theory. We focus on recent results on the epistemic foundations of solution concepts, including correlated equilibrium, rationalizability in dynamic games, forward and backward induction.

This paper develops a model of capacity-price competition in which the equilibrium outcome ranges from the Bertrand to the Cournot outcome as capacity constraints become more important. This model is employed to reexamine aspects of strategic-trade-policy theory and, in particular, the theory's...

The World Trade Organization (WFO) lacks the power to directly enforce agreements. It is, therefore, important to understand what role the WTO can play to facilitate international cooperation and whether a multilateral institution can offer distinct advantages over a web of bilateral agreements....

This paper examines equilibrium trade policies when firms have better information than governments about the profitability of the industry. Contrary to the intuition that the policymakers' lack of information should reduce their incentives to engage in strategic trade intervention, the analysis...

We examine a model of contracting where parties interact repeatedly and can contract at any point in time, but writing formal contracts is costly. A contract can describe the external environment and the parties' behavior in a more or less detailed way, and the cost of writing a contract is...

In this article I analyze strategic investment under uncertainty in a new market, where firms face a tradeoff between commitment and flexibility. The model predicts asymmetric equilibria under fairly general conditions, even though firms are ex ante identical and have symmetric opportunities to...
