For individual countries, variable trade barriers can be used to reduce the volatility of domestic relative to world prices. If this is done by countries accounting for a large share of the market, its effect is offset by increases in world price volatility. This study shows the nature of the...

National barriers to trade are often varied to insulate domestic markets from international price variability. This paper explores the extent of that behavior by governments using estimates of agricultural price distortions in 75 countries. Newly estimated price transmission elasticities are...

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

This paper addresses three questions relating to the very extensive use of the GTAP global trade protection database: Are there additional price-distorting policy instruments worthy of inclusion in the base year? What is the appropriate counterfactual set of price distortions in the year of...

Historically, earnings from farming in many developing countries have been depressed by a pro-urban bias in own-country policies, as well as by governments of richer countries favouring their farmers with import barriers and subsidies. Both sets of policies reduced global economic welfare 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 that 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...

Rapid economic growth in some emerging economies in recent decades has significantly increased their global economic importance. If this rapid growth continues and is strongest in resource-poor Asian economies, the growth in global demand for imports of primary products also will continue, to...

The recent upward spike in the international price of food led some countries to raise export barriers. As in previous price spike periods, that response by some food-exporting countries was accompanied by a lowering of import restrictions by numerous food-importing countries. Both actions...

Rapid trade-led economic growth in emerging Asia has been shifting the global economic and industrial centres of gravity away from the north Atlantic, raising the importance of Asia in world trade but also altering the commodity composition of trade by Asia and other regions. What began with...
