What can we expect our evolutionary history to tell us about human reproductive and family life? Each of us is a descendant of an unbroken line of males and females who survived to adulthood and somehow managed to mate and produce at least one offspring who also survived to adulthood, mated, and so on. For most economists, the hypothesis that human preferences are designed to maximize reproduct...

Wakker (1991) and Puppe (1990) point out a mistake in theorem 1 in Segal (1989). This theorem deals with representing preference relations over lotteries by the measure of their epigraphs. An error in the theorem is that it gives wrong eonditions eoneerning the eontinuity of the measure. This artiele eorreets the error. Another problem is that the axioms do not imply that the measure is bounded...

One of the oldest but least understood matching problems is Gale and Shapley’s (1962) “roommates problem”: is there a stable way to assign 2N students into N roommate pairs? Unlike the classic marriage problem or college admissions problem, there need not exist a stable solution to the roommates problem. However, the traditional notion of stability ignores the key physical constraint that roomm...

In this paper, we use a structural general-equilibrium approach to study whether the expenditureswitching role of exchange rates has changed in the G7 countries in the current episode of significant global imbalances. We develop a multi-sector two-country model for the United States and the G6 countries with the rest of the world captured by exogenous price and demand shocks, and estimate the m...

Many observers have argued that ethnic divisions make public goods more difficult to provide. This paper examines the provision of public goods in an economy with ethnic divisions. Households feel altruistically toward other households in their ethnic group. The amount of public goods in private contribution equilibrium is generally in decreasing in the amount of ethnic diversity. Public goods ...

Innovative activities have public good characteristics in the sense that the cost of producing, say, the …rst unit of a new good is high compared to the cost of producing subsequent units. Moreover, knowledge of how to produce subsequent units is often widely known once the innovation has occurred and is, therefore, non-rivalrous. The main question addressed in this paper is whether mechanisms ...
