In this paper we study the adjustment of a N-country world economy to an unfavourable common supply shock. We show that world-wide monetary policy coordination is essential to achieve an optimal adjustment to the common shock, but that its actual implementation requires careful design to ensure...

Should privately informed agents with diverging interests act independently or should they commit to a mechanism? This paper analyzes different communication and decision protocols when communication involves delay. It studies under which conditions agents should (i) choose their actions...

When an individual performs several tasks simultaneously, resources must be allocated to different brain systems to produce energy for neurons to fire. Following the evidence from neuroscience, we model the brain as an organization in which a coordinator allocates limited resources to the brain...

We model an international union as a group of countries deciding together the provision of certain public goods and policies because of spillovers. The countries are heterogeneous either in preferences and/or in economic fundamentals. The trade-off between the benefits of coordination and the...

We model an international union as a group of countries deciding together on the provision of public goods or policies that generate spillovers across members. The trade-off between benefits of coordination and loss of independent policy-making endogenously determines size, composition and scope...

We study budget formation in a model featuring separation of powers. In our model, the legislature designs a budget bill that can include a cap on total spending and earmarked allocations to designated public projects. Each project provides random benefits to one of many interest groups. The...

This Paper studies a principal-agent model of the relationship between officeholder and an electorate, where everyone is initially uninformed about the officeholder’s ability. If office-holder effort and ability interact in the determination of performance in office, then an office-holder has...

This Paper analyses an overlapping generation model of public good provision under repeated voting. The public good is financed through age-dependent taxation that distorts human capital investment. Taxes redistribute income both across different skill groups and across generations. We contrast...

We construct a set of indicators to measure the policy-making role of the European Union (European Council, Parliament, Commission, Court of Justice, etc.), in a selected number of policy domains. Our goal is to examine the division of prerogatives between European institutions and national...

It is well known that ex post efficient mechanisms for the provision of indivisible public goods are not interim individually rational. However, the corresponding literature assumes that agents who veto a mechanism can enforce a situation in which the public good is never provided. This paper...
