In 1998, the Swiss voters approved of an increase in female retirement age from 62 to 64. The referendum, being on a single issue only, offers a unique opportunity to explore the political feasibility of pension reforms and to apply theoretical models of life-cycle decision making. Estimates...

Group liability is often portrayed as the key innovation that led to the explosion of the microcredit movement, which started with the Grameen Bank in the 1970s and continues on today with hundreds of institutions around the world. Group lending claims to improve repayment rates and lower...

We introduce tax contracts and examine how they affect government formation and welfare of voters in a democracy with proportional elections. A tax contract specifies a range of tax rates a party is committed to if in government. We develop a new model of party competition in which parties...

Majority rules are frequently used to decide whether or not a public good should be provided, but will typically fail to achieve an efficient provision. We provide a worst-case analysis of the majority rule with an optimally chosen majority threshold, assuming that voters have independent...

In particular, we consider the case where lobbies have private information about their ability to exert influence. We find a new...
