Information is costly to acquire in trade and financial markets, especially across international borders. Sellers and buyers rely on information and experiences of other firms, including from business partners located in other countries. This Paper identifies three channels through 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...

The recent theoretical literature on the determinants of trade agreements has stressed the importance of political gains, such as credibility, as a rationale for trade agreements. The empirical literature, however, has lagged behind in the estimation of the economic gains or losses associated...

In the case of natural monopolies there tends to be a trade-off between a higher quality of output provided by private firms, and a better access for poor consumers provided by public firms. This is partly the reflection of differences in objectives by private and public firms. The former tend...

This paper uses a price-leadership model of the international vanilla market to study the welfare consequences of alternative pricing policies for Madagascar – a country that controls domestic production through a single-channel marketing system and is the leader in the vanilla market....

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...

This paper explores how political-economy forces shape quantitative barriers against the rest of the world in a FTA. We show that whereas the dilution of lobbying power in a FTA typically leads to a relaxation of external quotas, this result is likely to be overturned as integration deepens. In...

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 negotiations on trade in services at the WTO have so far produced little liberalization beyond levels unilaterally undertaken by countries. One reason is the neglect of the traditional negotiating principle of reciprocity. In particular, there has been a failure to exploit the scope built...

An influential literature argues that trade promotes knowledge flows and technology transmission between trading partners. This literature focuses on ‘direct’ R&D spillovers which are related to the levels of R&D produced by the trading partners. In this paper we argue that ‘indirect’...
