We analyse an experimental public goods game in which group members can endogenously determine whether they want to supplement a standard voluntary contribution mechanism with the possibility of rewarding or punishing other group members. We find a large and positive effect of endogenous...

The issue of the free movement of persons occupies center stage in the negotiations on EU enlargement. Opinion polls and household surveys reveal that a majority of EU citizens are fearful of the consequences of the free movement of persons. Influenced by these surveys, the EU Commission and...

This paper discusses the existence of 'home' biases in the 19th century global capital market, whereby colonies appear to have received a 'disproportionate' amount of capital from their metropolis. Starting from a discussion of the Bulow Rogoff (1989) problem, we argue that imperial links...

We use hedonic prices and purchase quantities to consider what can be learned about household willingness to pay for baskets of organic products and how this varies across households. We use rich scanner data on food purchases by a large number of households to compute household specific lower...

What determines the sustainability of sovereign debt? In this paper, we develop a model where myopic governments seek electoral popularity but can nevertheless commit credibly to service external debt. They do not default when they are poor because they would lose access to debt markets and be...

This paper aims to show that culture is an important determinant of the effectiveness of formal democratic institutions, such as elections. We collect new data to document the presence of voluntary and social organizations and the history of electoral reforms in Chinese villages. We use the...

This paper systematically examines the role of fiscal policy, trade and energy taxes on environmental quality in Europe using disaggregated data for 12 European countries over the 1995-2008 period. It uses a methodology that obtains estimates mostly free of time-varying omitted variable biases....

We examine debt-sensitive majority rules. According to such a rule, the higher a planned public debt, the higher the parliamentary majority required to approve it. In a two-period model we compare debt-sensitive majority rules with the simple majority rule when individuals differ regarding their...

This Paper establishes and explores the implications of a somewhat surprising empirical finding. Although civil war adversely affects the performance of social indicators in general, poorer countries lose less, in absolute and relative terms, than richer countries. It is argued that the...

This Paper studies a game of strategic experimentation with two-armed bandits whose risky arm might yield a pay-off only after some exponentially distributed random time. Because of free-riding, there is an inefficiently low level of experimentation in any equilibrium where the players use...
