While barriers to trade in most goods and some services including capital flows have been reduced considerably over the past two decades, many remain. Such policies harm most the economies imposing them, but the worst of the merchandise barriers (in agriculture and textiles) are particularly...

This is one of ten studies for the Copenhagen Consensus Project that sought to evaluate the most feasible opportunities to improve welfare globally and alleviate poverty in developing countries. It argues that phasing out distortionary government subsidies and barriers to international trade...

This paper explores the implications for trade relations of the greening of world politics. It modifies the standard theory of changing comparative advantages in a growing world economy to show the effects on trade of taking into account the fact that the demand for domestic environmental...

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...

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...

Most-favoured-nation (MFN) trade liberalizations will always improve global economic welfare provided globally optimal environmental, and other, policies are in place. But since the latter proviso is not met in practice, empirical studies of the environmental and resource depletion effects of...

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...

East Asia has rapidly become the third centre of gravity for global economic activity. North America is relatively well integrated with East Asia, but Europe is not. This paper explores the extent to which economic growth and trade policy developments over the next decade or so will strengthen...
