We consider the problem of reallocating the total initial endowments of an infinitely divisible commodity among agents with single-peaked preferences. With the uniform reallocation rule we propose a solution which satisfies many appealing properties, describing the effect of population and...

We show that, with benevolent policymakers and fiscal leadership, monetary unification reduces inflation, taxes and public spending. These disciplining effects of a monetary union, which rise with the number of fiscal players in the union, are likely to raise welfare. Joining an optimally...

This paper explores under what conditions a European Monetary Union (EMU) is an optimum currency area. The scope for an EMU increases with convergence of structural and fiscal policies, small money holdings, a conservative European Central Bank, and dependent national central banks. How national...

This paper explores how debt accumulation is affected by the strategic interactions between monetary and fiscal authorities. To achieve the second best with a dependent central bank, the government needs to be made both more conservative and more impatient. However, in the absence of political...

This paper explores how decentralized, national fiscal policies interact with a common monetary policy in a monetary union. We show that fiscal policy plays a more important role in stabilizing country-specific shocks than with national monetary policies. Whereas monetary unification with an...

A state, for instance a health state, is characterized by a number of attributes to each of which a level is assigned. A specific collection of numerical values, for instance utilities, for all possible states is called a situation. The main purpose of the paper is to develop a class of methods...

Under a k-approval scoring rule each agent attaches a score of one to his k most preferred alternatives and zero to the other alternatives. The rule assigns the set of alternatives with maximal score. Agents may extend preferences to sets in several ways: they may compare the worst alternatives,...

This paper is concerned with the number of profiles at which a nondictatorial social choice function is manipulable. For three or more alternatives the lower bound is derived when the social choice function is nondictatorial and unanimous. In the case of three alternatives the lower bound is...

This paper is concerned with the question of how to define the core when cooperation takes place in a dynamic setting. The focus is on dynamic cooperative games in which the players face a finite sequence of exogenously specified TU-games. Three different core concepts are presented: the...

Bargaining problems are considered where the preferences of the bargainers deviate from expected utility but can be modelled according to rank dependent utility theory. Under rank dependent utility two factors influence the risk attitude of a decision maker: the utility function and the...
