We analyse an oligopoly model in which differentiated criminal organizations compete on criminal activities and engage in corruption to avoid punishment. When law enforcers are sufficiently well-paid, difficult to bribe and corruption detection highly probable, we show that increasing policing...

This paper presents a model that explains why in the transition economies of Central and Eastern Europe an important output fall has been associated with price liberalization. Its key ingredients are search frictions and Williamsonian relation-specific investment implying that new investments...

Is competition for donations between development NGOs good for welfare? We address this question in a monopolistic competition model à la Salop (1979). NGOs - defined by the non-distribution constraint - compete for donations from donors by exerting fundraising effort. If the market size is...

In this paper, we offer a general analytical framework to illustrate the complex two-way interactions between trade and transnational terrorism. We then survey the recent economic literature in light of this framework by pointing to the importance in empirical studies a) to control appropriately...

We analyse the buy-back of its debt by an LDC. Contrary to the analyses that were previously done on this subject, we assume that the debtor can hide its transactions behind the veil of a fictitious operator: the banks, we assume, cannot discriminate intra-bank transactions from buy-backs by the...

This paper analyses the interplay between social structure and information exchange in two competing activities, crime and labour. We consider a dynamic model in which individuals belong to mutually exclusive two-person groups, referred to as dyads. There are multiple equilibria. If jobs are...

In this paper, the authors reconsider the basic model of "efficient rent-seeking." They stress the importance of the shape of the players' reaction curve in order to understand the impact of the technology of rent-seeking on the structure of the outcome of the game. The authors give a complete...

This article analyzes the links between the internal organization of the firm and macroeconomic growth. We present a Schumpeterian growth model in which firms face agency costs due to the existence of asymmetries of information and the formation of vertical collusions inside those firms. To...
