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 decades, trade between countries in agricultural products has been distorted by policies of richer countries favoring their farmers with import barriers and subsidies. Agricultural trade has often also been limited by an anti-agricultural, pro-urban bias in many developing country policies....

Food prices in international markets spiked upwards in 2008, doubling or more in a matter of months. Evidence is still being compiled on policy responses over the following two years, but new time series estimates of government intervention for the previous five decades allow insights into past...

A decline in governmental distortions to agricultural and other trade since the 1980s has contributed to economic growth and poverty alleviation globally. But new modeling results suggest that has taken the world only three-fifths of the way towards freeing merchandise trade, and that farm...

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...

For decades, agricultural price and trade policies in Sub-Saharan Africa hampered farmersÂ’ contributions to economic growth and poverty reduction. While there has been much policy reform over the past two decades, the injections of agricultural development funding, together with on-going...

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

AustraliaÂ’s lacklustre economic growth performance in the first four decades following World War II was in part due to an anti-trade, anti-primary sector bias in government assistance policies. This paper provides new annual estimates of the extent of those biases since 1946 and their...

For decades, earnings from farming in many low-income countries have been depressed by a pro-urban bias in own-country policies, as well as by governments of richer countries favoring their farmers with import barriers and subsidies. Both sets of policies reduce national and global economic...

Despite reforms over the past quarter-century, world agricultural markets remain highly distorted by government policies. Traditional indicators of those price distortions such as the nominal rate of assistance and consumer tax equivalent provide measures of the degree of intervention, but they...
