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...

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...

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 article reviews and synthesizes...

The Great Leap Forward (GLF) disaster, characterized by a collapse of grain output, and the associated famine in China between 1959 and 1961, can be attributed to a systemic failure in central planning. Encouraged by unrealistic expectations for agricultural productivity gains from...

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...

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...
