In repeated normal-form (simultaneous-move) games, simple penal codes (Abreu,1986, 1988) permit an elegant characterization of the set of subgame-perfect outcomes. We show that the logic of simple penal codes fails in repeated extensive-form games. By means of examples, we identify two types of...

Mechanisms according to which private intermediaries or governments charge transaction fees or indirect taxes are prevalent in practice. We consider a setup with multiple buyers and sellers and two-sided independent private information about valuations. We show that any weighted average of...

We design a laboratory experiment to test the importance of wealth as a channel for financial contagion across markets with unrelated fundamentals. Specifically, in a sequential global game, we analyze the decisions of a group of investors that hold assets in two markets. We consider two...

Empirical evidence suggests that money in the hands of mothers (as opposed to fathers) increases expenditures on children. From this, should we infer that targeting transfers to women is good economic policy? In this paper, we develop a non-cooperative model of household decision making to...

With politician preferences over policy outcomes, the effect of a contribution cap with monetary penalties for exceeding the cap is starkly different from the case with an indifferent politician. In contrast to Kaplan and Wettstein (AER, 2006) and Gale and Che (AER, 2006), a cap is never neutral...

We evaluate the well-known Fisher Equation in the context of accounting income with a focus on its implicit assumptions regarding capital maintenance. Our findings indicate that the Fisher Equation does not allow for a consistent conversion from nominal to real terms, given that it modifies the...
