Most of the world's poorest people depend on farming for their livelihood. Earnings from farming in low-income countries are depressed partly due to a pro-urban bias in own-country policies, and partly because richer countries (including some developing countries) favor their farmers with import...

The authors estimate the impact of global merchandise trade distortions and services regulations on agricultural value added in various countries. Using the latest versions of the Global Trade Analysis Project (GTAP) database and the GTAP-AGR model of the global economy, their results suggest...

This paper provides new estimates of the global gains from multilateral trade reform and their distribution among developing countries in the presence of trade preferences. Particular attention is given to agriculture, as farmers constitute the poorest households in developing countries but are...

Four West African nations have demanded that the World Trade Organization's Doha Development Agenda include a Cotton Initiative that involves two issues: cutting cotton subsidies and tariffs, and assisting farm productivity growth in Africa. The authors provide estimates of the potential...

The authors provide estimates of the economic impact of initial adoption of genetically modified (GM) cotton and of its potential impacts beyond the few countries where it is currently common. They use the latest version of the Global Trade Analysis Project (GTAP) database and model. The results...

The claim by global trade modelers that the potential contribution to global economic welfare of removing agricultural subsidies is less than one-tenth of that from removing agricultural tariffs puzzles many observers. To help explain that result, the authors first compare the OECD and...

When prices spike in international grain markets, national governments often reduce the extent to which that spike affects their domestic food markets. Those actions exacerbate the price spike and international welfare transfer associated with the terms of trade change. Several recent analyses...

This paper has two purposes. It first considers the impact on world food prices of the changes in restrictions on trade in staple foods during the 2008 world food price crisis. Those changes -- reductions in import protection or increases in export restraints -- were meant to partially insulate...

The agricultural and food sector is an ideal case for investigating the political economy of public policies. Many of the policy developments in this sector since the 1950s have been sudden and transformational, while others have been gradual but persistent. This paper reviews and synthesizes...

To what extent has Sub-Saharan Africa's slow economic growth over the past five decades been due to price and trade policies that discouraged production of agricultural relative to non-agricultural tradables? This paper uses a new set of estimates of policy induced distortions to relative...
