This paper examines why developed countries are monogamous while rich men throughout history have tended to practice polygyny (multiple wives). Wealth inequality naturally produces multiple wives for rich men in a standard model of the marriage market. This paper argues that the sources of...

This paper explores the relationship between income distribution, prices, production efficiency and aggregate output in a decentralized search economy. We show that income distribution determines how competitive the market is, and thereby affects production efficiency and aggregate output. It is...

This paper investigates whether the sources of income, not just the levels, determine whether an individual is monogamous. Our results support the idea that polygyny stunts development by allowing wealthy men to acquire wives rather than investing in child quality.

This paper uses variation created by parental deaths in the amount of time children spend with each parent to examine whether the parent-child correlation in schooling outcomes stems from a causal relationship. Using a large sample of Israeli children who lost one parent during childhood, we...

This paper estimates the contribution of nature and nurture to the variance of longevity in a cross section of individuals. Our approach differs from that used in the genetics and biological literature in that we develop a simple model of longevity determination and use it to bound the...

We present a model in which purely monetary inflation systematically affects efficiency, welfare, and relative prices. The model focuses on the microeconomics of trade in search markets under inflation. Inflation, by increasing the cost of holding money, undermines the market's ability to...

We present a model in which unemployed workers simultaneously sample n potential employers. By varying n, we nest search and Walrasian-type models of the labor market. We show that low values of n yield typical search equilibria: the wages are dispersed below the marginal productivity of labor....

We examine why developed societies are monogamous while rich men throughout history have typically practiced polygyny. Wealth inequality naturally produces multiple wives for rich men in a standard model of the marriage market. However, we demonstrate that higher female inequality in the...
