A socio-economic analysis of a sample of farms in Northern Côte d'Ivoire revisits two debates about the evolution of farming systems in sub-Saharan Africa. Taking into account the diversity of farming systems, the debates "Boserup vs. Malthus" and "competition vs. complementarity" between...

The literature on the evolution of farming systems in West Africa shows a large diversity of general theories on rural development. The purpose of this study is to revisit the theses of Malthus and Boserup and empirically test them on a case study of Northern Cote dIvoire. We have at our...

A socio-economic analysis of a sample of farms in Northern Cote d'Ivoire revisits two debates about the evolution of farming systems in sub-Saharan Africa. Taking into account the diversity of farming systems, the debates "Boserup vs. Malthus" and "competition vs. complementarity" between cotton...

After more than a decade of GM crops, literature reports farmers and consumers can gain significantly from the technology, despite the intellectual property rights assigned to the innovator. In this paper we assess the effect of heterogeneity on this distribution of benefits. A two dimensional...

The debate about the "quasi" moratorium on the release of GMOs in the European Union is on going. One of the major arguments that were put forward to delay the release of new traits was the one for more information. In this contribution we compare the situation for Bt-maize from the 1995 and...

In Senegal, one of the highest rice import-dependent countries in Sub-Saharian Africa, double cropping is recommended in the new national program for the Great Offensive for Food and Abundance (GOANA) to boost rice production. This target impels the respect of cropping calendar by using improved...

Since 1995, genetically modified organisms (GMOs) have been introduced commercially into US agriculture. These innovations are developed and commercialised by a handful of vertically coordinated “"life science”" firms who have fundamentally altered the structure of the seed industry....

We develop a welfare framework, which explicitly recognizes that research protected by intellectual property rights generates monopoly profits. The result is a simulation model, shaped to the European sugar sector, and enabling to assess the size and distribution of the benefits of transgenic...
