Based on forecasts of global population growth, food security will remain an important economic development issue over the next several decades. In addition, real food prices have risen in
recent years after decades of decline, bringing the issue of food security even further into the public spotlight. However, there is no global food shortage: the problem is one of moving food,
often across borders, from surplus production areas to deficit ones at prices that low-income consumers in developing countries can afford. Trade can be an excellent buffer for domestic
fluctuations in food supply. World output of a given food commodity is far less variable than output in individual countries so increased trade integration holds considerable potential to
stabilize food prices, boost returns to farmers and reduce the prices faced by consumers. Trade liberalization protects national food markets against domestic shocks by allowing more food to be
imported in times of shortage and exported in periods of plenty. Historically, however, most countries have chosen to take the opposite approach by restricting imports of food and discouraging
exports to keep domestic markets isolated from international shocks. Food commodity markets, therefore, remain highly distorted despite the wave of liberalization that has swept world trade
since the 1980s.In addition to examining the determinants of recent food price spikes, Trade Policy and Food Security explores the impact of food prices on economic welfare, and how the effect
of price changes on food security and economic welfare in developing countries can be mitigated through appropriate national policies at the border. It highlights the importance of both the
extension and continued application of existing WTO disciplines on trade-distorting agricultural trade policies as a key resolution to the collective action problem witnessed during the recent
food price spikes, whereby unilateral border policies--especially export controls--simply exacerbated the initial price increases.
