I solve numerically for stationary rational-expectations equilibria of a two-country, non-linear model of a storable commodity. With constant tariffs, price volatilities in both countries increase with an increase in the tariff rate of one country or with an increase in the storage cost in one...

A common-agency lobbying model is developed to help understand why North America and the European Union have adopted such different policies towards genetically modified food. Our results show that when firms (in this case farmers) lobby policy-makers to influence standards and consumers and...

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...

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...

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...

After a brief period of liberal agricultural policies, Central and East European (CEE) countries have begun to rely increasingly on price subsidies and trade restrictions. We outline the situation of CEE agriculture and describe current policies. Scarce government funds could be better used to...
