Using a sample of Harvard undergraduates, we analyze trust and social capital in two experiments. Trusting behavior and trustworthiness rise with social connection; differences in race and nationality reduce the level of trustworthiness. Certain individuals appear to be persistently more...

This paper presents a model of prosecutors' decision-making processes in which prosecutors (both federal and state) internalize some of the benefits of reducing crime, but also care about developing their own human capital. Since U.S. attorneys make their decision first, they have the...

Individuals invest in their local environments by volunteering, getting involved in local government, becoming informed about their political leaders, joining non-professional organizations and even gardening. Homeownership may encourage these investments because homeownership gives individuals...

When there are binding price controls, there are shortages and the allocation of goods across consumers may not be efficient. In general, the misallocation costs of price controls are first order, while the classic welfare losses due to undersupply are second order. This paper presents an...

This paper examines the optimal location-based redistribution policy and shows that adjustment for local price levels is occasionally optimal, but never for the reasons suggested by the popular press. First, the existence of a spatial equilibrium suggests that utility levels will be equalized...

The textbook graphical analysis of price control (see Figure 1) is inappropriate any time there is substantial consumer heterogeneity. In cases such as rental apartments, where one unit is usually the maximum bought per customer, and the downward slope of the demand function comes exclusively...

Crime rates are much higher in big cities than in either small cities or rural areas, and this situation has been relatively pervasive for several centuries. This paper attempts to explain this connection by using victimization data, evidence from the NLSY on criminal behavior and the Uniform...

The high degree of variance of crime rates across space (and across time) is one of the oldest puzzles in the social sciences (see Quetelet (1835)). Our empirical work strongly suggests that this variance is not the result of observed or unobserved geographic attributes. This paper presents a...

We examine the relationship between urban characteristics in 1960 and urban growth (income and population) between 1960 and 1990. Our major findings are that income and population growth move together and both types of growth are (1) positively related to initial schooling, (2) negatively...
