We argue that standard models that solve the paradox of voting do a bad job explaining the frequency of very close elections. We instead model head-to-head elections as a competition between incentive schemes to turn out voters. We show that elections are either heavily contested, and decided by...

Consider a decision maker who has to choose one of several alternatives, and who is imperfectly informed about the payoff of each of them. In each period, the decision maker has to decide whether to stop and take one of the alternatives, or to continue researching the alternatives. New...

We describe Peru's experience of chronic inflation through the 1970s and 1980s as a result of the need for inflationary taxation in a regime of fiscal dominance of monetary policy. Hyperinflation occurred when further debt accumulation became unavailable, and a populist administration engaged in...

We develop a systematic, functional approach to revealed preference tests based on completing preferences. Our approach is based on the notion of sequential closure, which generalizes the notion of transitive closure. We show that revealed preference tests developed for various decision theories...

We propose a model of political careers and electoral accountability, in an environment in which politicians may take bribes at different stages of their careers, and in which politicians actions are only imperfectly observed by voters. Our model throws light on relatively unexplored dynamic...

We consider a canonical two-period model of elections with adverse selection (hidden preferences) and moral hazard (hidden actions), in which neither voters nor politicians can commit to future choices. We prove existence of electoral equilibria, and we show that office holders mix between...

Can public mood swings that make all voters undergo an ideological shift towards a policy, hurt the electoral performance of that policy? The answer depends interestingly on the operations of an apolitical, viewership-maximizing dominant media. The media chooses news quality about fundamental...

We propose and develop an algebraic approach to revealed preference. Our approach dispenses with non algebraic structure, such as topological assumptions. We provide an algebraic axiom of revealed preference that subsumes previous, classical revealed preference axioms, and show that a dataset is...

We study minimal conditions for competitive behavior with few agents, adapting the strategic market game of Dubey (1982), Simon (1984) and Benassy (1986) to an indivisible good environment. We show that all Nash equilibrium outcomes with active trading are competitive if and only if there are at...
