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...

In many cases, aggregate data is used to make inferences about individual level behavior. If there are social interactions in which one person's actions influence his neighbor's incentives or information, then these inferences are inappropriate. The presence of positive social interactions, or...

Why are public-sector workers so heavily compensated with pensions and other non-pecuniary benefits? In this paper, we present a political economy model of shrouded compensation in which politicians compete for taxpayers' and public employees' votes by promising compensation packages, but some...

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...

People continue to live in many big American cities, because in those cities housing costs less than new construction. While cities may lose their productive edge, their houses remain and population falls only when housing depreciates. This paper presents a simple durable housing model of urban...

A central requirement in the design of a legal system is the protection of law enforcers from coercion by litigants through either violence or bribes. The higher the risk of coercion, the greater the need for protection and control of law enforcers by the state. This perspective explains why, in...

From the streets of Hong Kong to Ferguson, Missouri, civil disobedience has again become newsworthy. What explains the prevalence and extremity of acts of civil disobedience?This paper presents a model in which protest planners choose the nature of the disturbance hoping to influence voters (or...

Psychologists have long documented that we over-attribute people's actions to innate characteristics, rather than to luck or circumstances. Similarly, economists have found that both politicians and businessmen are rewarded for luck. In this paper, we introduce this “Fundamental Attribution...
