This Paper contributes ideas and analysis to the ongoing EU reform debate. It consists of three distinct parts: voting in the Council of Ministers, restructuring the ECB's Governing Council, and the setting of enlargement “examination” dates. The IGC currently focuses on Council voting,...

We present identification and estimation results for the 'collective' model of labour supply in which there are discrete choices, censoring of hours and non-participation in employment. We derive the collective restrictions on labour supply functions and contrast them with restrictions implied...

We examine a stark setting in which security or protection can be provided by self-governing groups of by for-profit entrepreneurs: kings, lords, or mafia dons. Though self-governance is best for the population, it faces problems of long-term viability. Typically, in providing security the...

The paper studies the political and economic determinants of inter-regional public transfers. It points to an important difference between two alternative federal fiscal constitutions. The paper shows that inter-regional transfers can be determined either by a federation-wide vote over a...

The empirical performance of macroeconomic exchange rate models is more than disappointing. This dismal result is also reflected in the forecasting capabilities of professional analysts: all in all, analysts are not in a position to beat naïve random walk forecasts. The root for this deficient...

We study a class of representation mechanisms, based on reports made by a random subset of agents, called representatives, in a collective choice problem with quasi-linear utilities. We do not assume the existence of a common prior probability describing the distribution of preference types. In...

We consider a bargaining model of the interaction between a government and interest groups in which, unlike existing models, neither side is assumed to have all the bargaining power. The government will then find it optimal to constrain itself in the use of transfer policies to improve its...

The Most-Favored Nation (MFN) clause has long been suspected of creating a free rider problem in multilateral trade negotiations. To address this issue, we model multilateral negotiations as a mechanism design problem with voluntary participation. We show that an optimal mechanism induces only...

Why do many democracies fail to reform their labor market institutions? We study the feasibility of reforms that include the compensation of the insiders for the removal of labor market regulations. In our model workers differ in their ability to perform well on a liberalized labor market. The...
