Why does illegal trade often flourish without formal enforcement, but sometimes fail? Why do illegal trade-reducing policies often fail? Why do States often appear to tolerate illegal trade? A model of trade with cops and robbers provides answers. `Safety in numbers' is a key element: the...

In the classic analysis of smuggling importers choose the optimal mix of legal and illegal trade, given trade taxes and the technology of detection. This paper introduces an inconvertible currency in the framework, so that illegal trade is valued at a rate higher than the (fixed) official...

The paper develops an analytical framework to discuss the determinants of the premium in the black market for dollars in Brazil. While the specific details of the model were chosen with the Brazilian case in mind, the structure of the model is quite general and suitable for application to black...

We develop an equilibrium model of ticket resale in which buyers' decisions in the primary market, including costly efforts to "arrive early" to buy underpriced tickets, are based on rational expectations of resale market outcomes. We estimate the parameters of the model using a novel dataset...

We empirically analyze the illicit trade in cultural property and antiques, taking advantage of different reporting incentives between source and destination countries. We thus generate a measure of illicit trafficking in these goods based on the difference between imports recorded in United...

Mutual causation of predation and trade induces novel effects of commercial policy in this paper. The model can explain trade volume responses to market widening initiatives that are otherwise puzzlingly 'too big' or 'too small'. Efficient commercial policy (broadly defined) depends crucially on...

This paper provides an economic analysis of underground gun markets drawing on interviews with gang members, gun dealers, professional thieves, prostitutes, police, public school security guards and teens in the city of Chicago, complemented by results from government surveys of recent arrestees...

This paper examines the effect of drug prohibition on the black market prices of cocaine and heroin. The paper examines the ratio of retail to farmgate price for cocaine, heroin, and several legal goods, and it compares legal versus black market prices for cocaine and heroin. The results suggest...

A central parameter for evaluating tax policies is the price elasticity of demand for cigarettes. But in many countries this parameter is difficult to estimate reliably due to widespread smuggling, which significantly biases estimates using legal sales data. An excellent example is Canada, where...

China's trade has three features: high incidence of re-exports through Hong Kong, high degree of trade related to foreign investment, and large amount of `illegal' trade. Re-exports occur when imports to Hong Kong are consigned to a buyer in Hong Kong, who adds a markup, and exports the goods...
