Although average tariffs in Quad markets are very low, tariff peaks and tariff escalation have a disproportional effect on exports from least developed countries (LDCs). Tariff peak products tend to be heavily concentrated in agriculture and food products and in labour-intensive sectors such as...

High levels of protection and domestic support for farmers in developed countries significantly affect many least developed countries (LDCs), both directly and through the price-depressing effect of agricultural support policies. High tariffs and domestic support may also lower the world price...

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...

Exporters’ performance in a particular market may affect their future exports to the rest of the world. Importers may base their future transaction decisions upon the information revealed by exporters’ past performance in other countries. Similarly, exporters acquire valuable information on...

This paper extends the influence-driven model of trade policy determination to include general equilibrium effects on the supply side resulting from labour-market interaction and intermediate goods. The model’s predictions for the structure of protection are related to underlying taste and...

Using an extension of the influence-driven lobbying approach developed by Grossman and Helpman, we study the impact of regional integration arrangements (RIAs) on trade policy towards non-members in a three-good, three-country model. We explore under what conditions the formation of an RIA...

We compare the impact of distance, a standard proxy for trade costs, on eBay and offline international trade flows. We consider the same set of 62 countries and the same basket of goods for both types of transactions. We find the effect of distance to be on average 65 percent smaller on the eBay...

During the recent financial crisis many countries resorted to protectionist measures to try to boost demand for domestically-produced goods. In this paper we explore the extent to which the adoption of protectionist measures led to retaliation by other countries undermining the increase in...

We embed a model of the labor market with sector-specific search-and-matching frictions into a Ricardian model with a continuum of goods to show that trade liberalization causes higher unemployment in countries with comparative advantage in sectors with strong labor market frictions and leads to...

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...
