This paper studies the assignment of decision makers to two committees that make decisions by a simple majority rule. There is an even number of decision makers at each of various skill levels and each committee has an odd number of members. Surprisingly, even with the symmetric assumptions in...

This paper analyzes how to allocate experts into committees that use the unanimity rule to make decisions. We show that an optimal allocation of experts is extremely asymmetric. To reach the optimal allocation, therefore, one needs only to rank the experts in terms of their abilities and then...

This paper evaluates the Stability and Growth Pact. After examining the rules in place and the experience so far, the Pact is analysed from a political economy perspective, focusing on the choice for so-called soft law and drawing inferences from characteristics of successful fiscal rules at the...

We test whether, in addition to economic conditions, IMF credit is influenced by political factors. On the basis of a panel model for 128 countries over the period 1972-1998, we find that debt service scaled to exports, international reserve holdings scaled to imports and economic growth, as...

We consider a framework where the optimal decision rule determining the collective choice depends in a simple way on the decision makers’ posterior probabilities of a particular state of nature. Nevertheless, voting is generally an inefficient way to make collective choices and this paper...

The traditional criticism notwithstanding, we show that social mobility can, in principle, explain political income redistributions. Nonetheless, the social-mobility argument for redistribution is not satisfactory, as actual transition probabilities are not consistent with order-preserving...

We determine the scoring rule that is most likely to select a high-ability candidate. A major result is that neither the widely used plurality rule nor the inverse-plurality rule are ever optimal, and that the Borda rule is hardly ever optimal. Furthermore, we show that only the almostplurality,...
