Cross-Country Disparity in Agricultural Productivity: Quantifying the Role of Modern Seed Adoption

Inequality of agricultural labour productivity across the developing world has increased substantially over the past 40 years. This article asks: to what extent did the diffusion of Green Revolution seed varieties contribute to increasing agricultural labour productivity disparity across the developing countries? We find that 22 per cent of cross-country variation in agricultural labour productivity can be attributed to the diffusion of high-yielding seed varieties across countries, and that the impact of such diffusion differed significantly across regions. We discuss the implications of these findings for policy directed at increasing agricultural labour productivity in the developing world.     

Why the CCM won't lose: the roots of single-party dominance in Tanzania

This paper provides an empirical investigation of the factors contributing to single-party dominance in Tanzania. Despite the fact that Tanzania has had a multi-party democracy since 1995, the party which governed during single-party rule, the Chama Cha Mapinduzi (CCM), has won the vast majority of seats in the National Assembly in the first four multi-party elections. In order to understand the CCM's grip on power, this article analyses the results of a survey conducted amongst subsistence farmers in Tanzania, which provides information on farmers’ livelihood conditions, access to media and political views, and hence provides insight into the preferences underlying voting behaviour. It discusses the dominant reasons for CCM support, as well as the characteristics of farmers who are more likely to support an opposition party. It concludes by discussing possible policy options for enhancing political competition in Tanzania.
