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...

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...

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 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...
