El testigo experto
Un testigo es un tercero ajeno a la controversia de partes que aporta información específica como prueba testimonial. En esta expresión polisémica, con naturaleza compartida y efectos probatorios complementarios, por un lado, aparece el denominado testigo técnico conectado al caso, relevante por su presencia fáctica y su conocimiento o dominio del saber relacionado con los hechos ex ante al evento; por otro lado, se identifica al testigo perito s…
The Deterrent Effect of Surveillance Cameras on Crime
From the U.S. to Colombia to China, millions of public surveillance cameras are at the core of crime prevention strategies. Yet, we know little about the effects of surveillance cameras on criminal behavior, especially in developing economies. We study an installation program in Medellín and find that the quasi‐random allocation of cameras led to a decrease in crimes and arrests. With no increase in the monitoring capacity and no chance to use ca…
Scarcity without Leviathan
This paper asks whether scarcity increases violence in markets that lack a centralized authority. We construct a model in which, by raising prices, scarcity fosters violence. Guided by our model, we examine this effect in the Mexican cocaine trade. At a monthly frequency, scarcity created by cocaine seizures in Colombia, Mexico's main cocaine supplier, increases violence in Mexico. The effects are larger in municipalities near the United States, …
On the Effects of Enforcement on Illegal Markets
This paper studies the effects of enforcement on illegal behavior in the context of a large aerial spraying program designed to curb coca cultivation in Colombia. In 2006, the Colombian government pledged not to spray a 10 km band around the frontier with Ecuador due to diplomatic frictions arising from the possibly negative collateral effects of this policy on the Ecuadorian side of the border. We exploit this variation to estimate the effect of…

Illicit Trade and the Global Economy
Economists explore the relationship between expanding international trade and the parallel growth in illicit trade, including illegal drugs, smuggling, and organized crime. As international trade has expanded dramatically in the postwar period—an expansion accelerated by the opening of China, Russia, India, and Eastern Europe—illicit international trade has grown in tandem with it. This volume uses the economist's toolkit to examine the economic,…
Cocaine Production And Trafficking
The main purpose of this chapter is to summarize the information currently available oncocaine production and trafficking. The chapter starts by describing the available dataon cocaine production and trade, the collection methodologies, (if available) used bydifferent sources, the main biases in the data, and the accuracy of different data sources.Next, the chapter states some of the key empirical questions and hypotheses regardingcocaine product…
