Despite recent reforms, world agricultural markets remain highly distorted by government policies. Traditional indicators of those price distortions can be poor guides to the policies’ economic effects. Recent theoretical literature provides indicators of trade- and welfare-reducing effects of...

Australia’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 gradual...

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...

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 farmers’ 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...

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...

The regional books that provided detailed estimates of distortion in developing economies are all country focused. While they include commodity details for their particular country, they are not able to provide an overview for developing countries or high-income countries as a group, or for the...

For decades the world's agricultural markets have been highly distorted by government policies, but differently for different commodities such that a ranking of weighted average nominal rates of assistance across countries can be misleading as an indicator of the trade or welfare effects of...

For decades, agricultural price and trade policies in Sub-Saharan Africa hampered farmers' contributions to economic growth and poverty reduction. This paper draws on a modification of so-called trade restrictiveness indexes to provide theoretically precise partial-equilibrium indicators of the...
