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 sheds...

Our paper seeks to provide an explanation for why the prevalence of COLA provisions and their characteristics vary widely across U.S. industries. We develop models of optimal risk sharing between a firm and union that allows us to investigate the determinants of a number of characteristics of...

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 provides a novel justification for using a minimum wage to supplement an optimal tax-and-transfer system. We demonstrate that if labor supply decisions are concentrated along the intensive margin and employment is efficiently rationed, a minimum wage can be socially beneficial by...

This paper shows that a graduated minimum wage, in contrast to a constant minimum wage, can provide a strict Pareto improvement over what can be achieved with an optimal income tax. The reason is that a graduated minimum wage requires high-productivity workers to work more to earn the same...

This paper analyzes the effects of introducing a graduated minimum wage in a model with optimal in-come taxation in which a government seeks to maximize social welfare. It shows that the optimal graduated minimum wage increases social welfare by increasing the lowproductivity workers'...

The minimum wage rate has been introduced in many countries as a means of alleviating the poverty of the working poor. This paper shows, however, that an imperfectly enforced minimum wage rate causes small firms to face an upward-sloping labor supply schedule. Since this turns these firms into...

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...
