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...

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...

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...

Agricultural markets in OECD countries have long been highly distorted by government policies. Traditional weighted average aggregates of the price distortions involved, such as producer and consumer support estimates (PSEs and CSEs), can be poor indicators of the trade restrictiveness and...

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, this paper first compares the OECD and...

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...

The first generation of genetically modified crop varieties, currently most widespread in the maize and soybean sectors, sought to increase farmer profitability by improving agronomic traits. The next generation of biotech research is focusing also on breeding for attributes desired by...

Trade negotiators and policy advisors are keen to know the relative contribution of different farm policy instruments to international trade and economic welfare. Nominal rates of assistance or producer support estimates are incomplete indicators, especially when (especially in developing...
