In a world with volatile food prices, countries have an incentive to shelter their populations from induced real income shocks. When some agents are net food producers while others are net consumers, there is scope for insurance between the two groups. A domestic social protection scheme would...

This paper investigates the link between export survival of agri-food products and financial development. It tests the hypothesis that financial development differentially affects the survival of exports across products based on their need of external finance. The authors test whether exports of...

The food commodity price increases beginning in 2001 and culminating in the food crisis of 2007/08 reflected a combination of several factors, including economic growth, biofuel expansion, exchange rate fluctuations, and energy price inflation. To quantify these influences, the authors developed...

National barriers to trade are often varied to insulate domestic markets from international price variability, especially following a sudden spike. This paper explores the extent of that behavior by governments in the case of agricultural products, particularly food staples whose prices have...

This paper investigates the link between competitive, well-functioning food markets and consumer welfare. The paper explores two key food markets in Kenya -- sugar and maize -- and argues that a variety of factors conspire to distort market prices upward. Distortionary factors include import...

Liberalization in commodity markets has brought profound changes in the way price risks are allocated and managed in commodity subsectors. Price risks are increasingly allocated to private traders and farmers rather than absorbed by the government. The success of market reform depends on the...

The authors examine the price linkages among polyester (the dominant chemical fiber), cotton (the dominant natural fiber), and crude oil (the dominant energy commodity), based on monthly data between 1980 and 2002. The modeling framework incorporates several aspects of the unit root econometrics...

It is a common perception that primary commodity prices tend to move together. This perception is especially common among commodity traders who may justify an increase in the price of one commodity because the prices of other commodities have increased. This commodity price co-movement can be...

During the past decade, cotton prices remained considerably below other agricultural prices (although they recovered toward the end of 2010). Yet, between 2000-04 and 2005-09 world cotton production increased 13 percent. This paper conjectures that biotechnology-induced productivity improvements...
