Why do rational politicians choose inefficient policy instruments? Environmental regulation, for example, often takes the form of technology standards and quotas even when cost‐effective Pigou taxes are available. To shed light on this puzzle, we present a stochastic game with multiple...

I consider a heterogeneous federal system in which policy coordination is desirable but underprovided in the absence of a federal intervention. To improve policy coordination, the federal layer can intervene by imposing bounds on local policies. These federal bounds define a restricted policy...

We compare centralized and decentralized policy making in a federation in which policy heterogeneity is inherently costly and preferences vary across jurisdictions: all jurisdictions agree that some harmonization is desirable but no one agrees on the direction of harmonization. This type of...

I analyze a game between an uninformed decision maker and a possibly biased expert. The expert receives a set of arguments, and each argument favors one of two alternatives. He can disclose each argument credibly, but cannot prove whether he has disclosed everything. In all equilibria, the...

We propose a model of delegated asset management that can explain the following empirical regularities in international markets: the presence of home bias, the lower proportion of mutual funds investing domestically, and the higher market value of mutual funds investing domestically. In the...

Electoral incentives may lead policymakers to eschew opportunities for common-interest reform, focusing instead on zero-sum, partisan policymaking. By forgoing opportunities for common-interest reforms, incumbents may convince their constituents that such reforms are rarely feasible, so that...
