To study the effects of tariffs on GDP one needs import demand elasticities at the tariff line level that are consistent with GDP maximization. These do not exist. We modify Kohli’s (1991) GDP function approach to estimate demand elasticities for 4625 imported goods in 117 countries. Following...

The objective of this paper is to provide indicators of trade restrictiveness that include both measures of tariff and non-tariff barriers for 91 developing and developed countries. For each country, we estimate three trade restrictiveness indices. The first one captures the extent to which...

The objective of this paper is to estimate the potential pro-poor bias in the existing structure of protection in six countries in Sub-Saharan Africa (SSA) (i.e., whether it redistributes income from rich to poor households). We also explore the extent to which the barriers faced by SSA...

A rationale for cooperation in trade negotiations is the internalization of terms-of-trade externalities. With the help of a simple theoretical framework we show that the textbook prediction that non-cooperative tariffs are positively correlated to the importer's market power is reversed when...

This Paper assesses the foreign lobbying forces behind the tariff preferences that the United States grants to Latin American countries. The basic framework is one developed by Grossman and Helpman (1994) that is extended to explain the relationship between foreign lobbying and tariff...

Since the early 1990s, numerous countries have adopted or strengthened competition legislation. In this Paper we investigate the impact of competition law on industry markups over time and across a large number of countries. We find both domestic and foreign competition to be major sources of...

Actual and potential competition is a powerful source of discipline on the pricing behavior of firms with market power. A simple model is developed that shows that the effects of import competition and domestic entry regulation on industry price-cost markups depend on country size. Barriers to...
