We analyze the evolution of Sub-Saharan Africa's (SSA's) agricultural total factor productivity (TFP) over the past 45 years, looking for evidence of recent changes in growth patterns using an improved nonparametric Malmquist index. Our TFP estimates show a remarkable recovery in the performance...

During the 2003/04–2008/09 period agricultural production in Ethiopia grew annually at 9.3 percent while cultivated area expanded at 4.7 percent. The remaining growth resulted from intensive use of other inputs, increased productivity, increased efficiency, or a combination of these...

This research has been undertaken to understand the rationale for the implementation of decreasing export taxes along the value chain in middle-income countries, in particular in the oilseeds value chain. This paper studies the implementation of Differential Export Tax (DET) rates along value...

This theoretical paper intends to provide an explanation of the implementation of behind-the-border policies, border policies, and of the inefficiency of trade negotiations. We consider a general equilibrium model of international trade with two identical countries, two commodities, a...

In developing countries across Asia, food marketing parastatals have played an important role in agricultural policy, especially with regard to government efforts to stabilize food prices. Three broad market failures constitute the primary arguments for this form of government intervention: a...

The food price crisis of 2007–2008 and recent resurgence of food prices have focused increasing attention on the causes and consequences of food price volatility in international food markets and the developing world, particularly in Africa south of the Sahara. In this paper, we examine...

The aim of this paper is to assess of the impact of the European Union’s trade preferences on global trade, focusing on several methodological issues that are relevant to the trade-creating impact of these preferences. Using highly disaggregated eight-digit data in a theoretically...

The extent to which Bangladesh should rely on imports for rice price stabilization is a contentious policy issue. This issue was underscored in the wake of the 2007–08 world food crisis, during which international rice prices skyrocketed and rice import supplies from India were disrupted....
