We introduce a simple and robust approach to answering two key questions in empirical auction analysis: discriminating between models of entry and quantifying the revenue gains from improving auction design. The approach builds on Bulow and Klemperer (1996), connecting their theoretical results...

We develop a dynamic political-economic theory of welfare state and immigration policies, featuring three distinct voting groups: skilled workers, unskilled workers, and old retirees. The essence of inter- and intra-generational redistribution of a typical welfare system is captured with a...

The standard approach to policy-making and advice in economics implicitly or explicitly ignores politics and political economy, and maintains that if possible, any market failure should be rapidly removed. This essay explains why this conclusion may be incorrect; because it ignores politics,...

We provide a potential explanation for the absence of, and unwillingness to create, centralized power in the hands of a national state based on the political agenda effect. State centralization induces citizens of different backgrounds, interests, regions or ethnicities to coordinate their...

A majority of the world democracies are far from the benchmark of representative democracy. This paper presents a model of political transitions based on a minimalist conception of the democratic state, i.e. a form of government solely characterized by competitive elections. We show that the...

It is widely believed that politicians allocate public resources in ways to maximize political gains. But what is less clear is whether this comes at a cost to welfare; and if so, whether alternative electoral rules can help reduce these costs. In this paper, we address both of these questions by...

This paper presents a theoretical and empirical investigation of tax competition when voters use the tax policy of neighboring jurisdictions as information to evaluate the performance of their incumbent politicians. We show that this has implications both for voter tolerance of high taxes and...

This paper examines the pattern of change in turnout in elections and in the rate of voting of different socioeconomic groups in the US. It shows that while the changing education and income structure of the population and changes in laws and regulations that make it easier to register and to...

We study the properties of the group-based model of voting in elections with more than two candidates. We consider two of the most widely used electoral rules around the world: plurality and majority runoff. We fully characterize the set of equilibria under both rules and identify the features...

We use a simple graphical approach to represent Social Welfare Functions that satisfy Independence of Irrelevant Alternatives and Anonymity. This approach allows us to provide simple and illustrative proofs of May's Theorem, of variants of classic impossibility results, and of a recent result on...
