The major objective of this paper is to discuss the development of rural labor markets in China during the past two decades and understand how it has affected women. Using household survey data that we collected in 2001, we examine the role of women in labor markets by examining employment and migration trends and changes in wages. According to the data of our nearly national representative sample, we find that there has been a sharp overall increase in off-farm participation, most of the increase has been driven by young migrants, and women, especially those in the youngest cohorts, have participated at rates equaling or surpassing those of their male counterparts. We also find that the wages of women have not been adversely affected by the emergence of liberalized labor markets and that when women, mostly middle-aged and older ones, are left in charge of farm work, the productivity of crop production does not fall.

Although there is broad agreement that well functioning land rental markets will play an important role to increase productivity and household welfare as agrarian economies develop, evidence from Africa on the actual performance and impact of such markets is limited. We use data from Uganda to test for differences in the performance of rental, as compared to sales markets and their evolution over time, based on a framework where markets are affected by differences in ability and imperfections in rural labor and capital markets.

We find that land markets are very active, that land rental but not sales markets transfer land to more efficient and relatively poor producers thereby providing an opportunity for the landless to access land, and that rental market activity has increased recently with economic growth. Despite land prices in some regions being above the net present value of land we find no evidence for sales markets leading to land concentration and conclude that, rather than imposing administrative restrictions, government should aim to improve access to alternative savings instruments.

The optimal level of formalisation of contracts and their dynamic is at stake in the economic literature on the optimum design of ex post renegotiation with third party enforcement. Another theoretical interpretation is that contract adaptations may also reflect mutual learning process between contractors. Why transactors write explicit contract that they know cannot be court enforced ?

The central idea is that explicit contract terms makes it clearer to the transactors what has been agreed upon, thus are decreasing the cost of private enforcement sanctions (Klein, 1996). Empirical evidences are provided by the diachronic analysis of the full set of tri-partite contracts between one of the top-ten french large retailer and its beef suppliers before and after the BSE crisis (period 1993-1999). The analysis emphasizes also the role of this increased codification of supply contracts with a progressive change in the internal retailer’s organization, i.e. increased centralization of decision and supervision mechanisms. Contract design and organizational choices are then strongly interrelated.

This essay seeks to shed light on the causes and potential consequences of restricted germplasm flows among nations. My objective is to provide a synthesis of existing literature and events of which I was a part, with a focus on food security in poor countries. Regrettably, the mechanisms restricting flows are complicated, the data on the size and direction of flows are meager, the outcomes are uncertain, and the policy mechanisms for alleviating the problems are largely untested. My general hypothesis is that four separate forces are now interacting in ways that should worry everyone concerned with the transfer of technology, particularly improved crop varieties, to scores of the world’s poorest nations. These elements include: new provisions on intellectual property, especially patenting in the United States; an increased concentration of new enabling technologies into a few large multinational companies; heightened anxieties over transgenic foods, especially in Europe; and new problems arising from old ambiguities in the Convention on Biodiversity. Individually, these components are reasonably well understood. Collectively, however, they are poorly understood, and their combined impact on the poorer countries of the world is very troublesome.

The main objective of this paper is to analyse the structural changes in European Agri-food systems in the last 30 years in order to verify the presence of a convergence process towards a more homogeneous structure among EU countries. This analysis considers the relative importance of the main components of Agri-food systems (agriculture, food industry and food consumption) and how they change over time. The analysis of convergence utilise the European National Accounting Data (from the SEC2 Data Base of Eurostat) from 1970 to 2000 for twelve EU countries. We use tests of convergence on cross section data by countries, but also stochastic kernel methodologies to verify the dynamic evolution of groups of countries inside the EU. The results show there are important process of convergence among countries for the variables of the Agri-food system that are more linked to the economic development, such as the importance of agriculture and food consumption in GDP. On the other hand there are divergences on the variables more linked to the openness degree and to the competitiveness of the Agri-food system. The presence of polarisation process among groups of countries contribute to permanence of long run structural changes among Northern and Southern countries in the EU.
