Although average Organisation for Economic Co-operation and Development (OECD) tariffs on imports from the least developed countries are very low; tariffs above 15 percent have a disproportional effect on their exports. Products subject to tariff peaks tend to be heavily concentrated in...

High levels of protection and domestic support for farmers in industrial countries significantly affect many developing countries, both directly and through the price-depressing effect of agricultural support policies. High tariffs - in both rich and poor countries - and domestic support may...

Country size matters in determining the effectiveness of domestic and foreign competition on pricing behavior in manufacturing. Removing barriers to the entry of new firms reduces markups more in large countries, while removing barriers to imports reduces markups more in small countries.Actual...

Such "tariff peaks" are often concentrated in products developing countries want to export: agricultural,...

Actual, and potential competition is a powerful source of discipline on the pricing behavior of firms with market power. The authors develop a simple model that shows that the effects of new entry, and import competition on industry price-cost markups, depend on country size. The authors...
