We build a simple model of quantity competition to analyze the effect of switching costs on equilibrium behavior of duopolists. We characterize the industry structure as a function of initial sales of two firms. Contrary to the literature, initial asymmetries persist in our model even though the...

We analyze the role of accounting specialists who help corporations evade/avoid taxes in a game of incomplete information played by a tax authority, corporate taxpayers, and an accounting specialist. In addition to a full equilibrium characterization, we establish that (i) marginal changes in...

We analyze the tax evasion problem with social interaction among the taxpayers. If the authority commits to a fixed auditing probability, a positive share of cheating is obtained in equilibrium. This stands in contrast to the existing literature, which yields full compliance of audited taxpayers...
