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 closed economies display no relationship at all. This stylized fact...

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 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 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 lays out an econometric strategy for estimating the effect of advertising on prices, by exploiting seasonal demand and imperfect targeting. We present two simple models of duopoly where firms choose prices and advertising. In times of high demand for the product, a larger fraction of...
