[eng] Thierry Deffarges — The cocaine economy : Elements of a quantitative and qualitative analysis.. The cocaine economy is subject to imperfect and incomplete information due to its illegal nature. Besides, analyses of interactions between production and consumption are missing. The purpose of this article is thus methodological, empirical and theoretical. From a purely deductive method, the author seeks to assess the importance of cocaine supply and demand.

[eng] Thierry Deffarges — On the nature and causes of terrorism : A review of the economic literature . This article proposes a critical appraisal of the economic literature devoted to terrorism. On the one hand, contributions, based on standard economic methods and new micro-economy methods, attempt to determine the rationality of a violence whose objectives are political, on the other hand, they seek to determine the economic causes. The author hereby attempts to show that the formal methods of economics can but only be partially useful in addressing the issue of terrorism, especially as regards the meaning attached thereto.

[eng] Thierry Defarges — The new trade regime and wage disparities in Latin America. . This article analyses the causalities between external liberalisation and the increase of wage disparities in Latin America during the 1990s. The direct effects of the international insertion of these countries on relative wage variations exist, but the main force results from the indirect effects of external liberalisation. Exposure to international competition happens to favour a qualified workforce, thus inducing an asymmetric wages adjustment that negatively affects unqualified labour. The dynamics of relative wages therefore simultaneously expresses the improvements in productive efficiency and cost-effects.
