We consider a neoclassical growth model with endogenous corruption. Corruption and wealth, which are co-determined in equilibrium, are shown to be negatively correlated. Richer countries tend to be less corrupt, and corrupt economies tend to be poorer. This observation gives rise to the...

We report an intriguing empirical observation. The relationship between corruption and output depends on the economy's degree of openness: in open economies, corruption and GNP per capita are strongly negatively correlated, but in closed economies there is no relationship at all. This stylized...

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...

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...

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...
