Africa has great potential for agriculture. Although international commodity prices have been buoyant, Africa?s supply response seems to be weak. A variety of constraints may exist. Using the case of Tanzania, the paper examines the impact of market connectivity, domestic and international, on...

Nonseparable household models outline the links between agricultural production and household consumption, yet empirical extensions to investigate the effect of production on dietary diversity and diet composition are limited. Although a significant literature has investigated the calorie-income...

Diversification into high-value cash crops among smallholders has been propagated as a strategy to improve welfare in rural areas. However, the extent to which cash crop production spurs projected gains remains an under-researched question, especially in the context of market imperfections...

The 2014-15 Ebola epidemic took a devastating human and economic toll on three West African countries, of which Liberia was perhaps the hardest hit. The pathways through which the crisis affected economic activity in these largely agrarian societies remain poorly understood. To study these...

This paper presents early evidence from the first large-scale randomized-controlled trial of a land formalization program. The study examines the links between land demarcation and investment in rural Benin in light of a model of agricultural production under insecure tenure. The demarcation...

Farmers in developing countries face a wide array of risks. Yet they often lack formal financial instruments to protect against risks. This paper examines the impact on consumption, investment, and welfare of the separate provision of three financial products: weather insurance, savings, and...

This study estimates marginal increase in malnutrition for children ages 1-3 years from exposure to an extreme shock in the West African Sahel. The study uses knowledge of a child's birth and high resolution spatial and temporal distribution of shocks, calculated from the Normalized Difference...

Trafficking is an emerging concern in West Africa. In 2011, 17 percent of all cocaine consumed in Europe -- 21 tons -- passed through the region, for a retail value of US$1.7 billion. This paper discusses the evolution of trafficking in the region and provides estimates of the size and value of...

Mobile phone coverage has expanded considerably throughout the developing world, particularly within sub-Saharan Africa. Existing evidence suggests that increased access to information technology has improved agricultural market efficiency for consumer markets and certain commodities, but there...

This paper presents a new type of land market analysis relevant to cities with plural tenure systems as in West Africa. The methodology hinges on a systemic analysis of land delivery channels, which helps to show how land is initially made available for circulation, how tenure can be formalized...
