We contribute to the debate on how to assess the size of the shadow economy by proposing a reinterpretation of the traditional Currency Demand Approach (CDA) a là Tanzi. In particular, we introduce three main innovations. First, we take a direct measure of cash transactions (the flow of cash...

In 2016 the city of Bogotá doubled police patrols and intensified city services on high-crime streets. They did so based on a policy and criminological consensus that such place-based programs not only decrease crime, but also have positive spillovers to nearby streets. To test this, we worked...

We study the effects of broken windows policing on crime using geo-located crime and arrest reports for 80 Colombian cities. Broadly defined, broken windows policing consists of intensifying arrests—sometimes for minor offenses—to deter potential criminals. To estimate causal effects, we...

As in many cities, gangs in Medellín provide order and collect 'taxes'. Why do gangs govern civilians? Some argue that criminal and state rule are substitutes. Hence, increasing state presence should crowd out gangs. But they could also be complements. States produce growth and general demand...

Organized crime affects security, development, and democracy worldwide, but not much is known about its social consequences. We study how exposure to the presence of organized crime groups shapes the social capital of Italian citizens, including political participation, civic engagement, and...

This paper provides a framework within which to study the equilibrium impact of alternative policies. We develop an overlapping generation, life-cycle model with endogenous education and crime choices. Education and crime depend on different dimensions of heterogeneity, which takes the form of...

This paper studies the effects of both labor market conditions and asset poverty on the property crimes involvement of American males. Since the mid 60's the property crimes arrest rate has been four times higher for black males if compared to white ones. Another set of stylised facts show for...

I develop a dynamic model of behavior to analyze juvenile crime. Forward-looking youths consistently decide between crime and legal activities depending on their endowment of work- and crime-specific human capital, which in turn is shaped by their history of past choices. The model explicitly...

An intertemporal general equilibrium model of criminal behavior is used to analyze the effect on crime of changing policy parameters. The policy parameters are the length of the prison term, the severity of punishment, and the amount of police resources. The number of crimes in society can be...
