This chapter discusses whether and how .new quantitative trade models.(NQTMs) can be fruitfully applied to quantify the welfare effects of trade liberalization, thus shedding light on the trade-related effects of further European integration. On the one hand, it argues that NQTMs have indeed the...

Since a speech by the Prime Minister in January 2013 , the Conservative party has been committed to holding a referendum on the UK's membership of the European Union (EU) in 2017. So this is a good moment to consider what would be the likely economic effects on the UK from such a move (commonly...

We analyze the effects of Brexit on the UK economy. The most important economic consequence of Brexit would likely be reduced trade with EU countries. We consider an optimistic scenario with relatively small increases in trade barriers between the UK and the EU and a pessimistic scenario with...

Firms need to incur substantial sunk costs to break in foreign markets, yet many give up exporting shortly after their first experience, which typically involves very small sales. Conversely, other new exporters shoot up their foreign sales and expand to new destinations. We investigate a simple...

Weak enforcement of international contracts can substantially reduce international trade. We develop a model where agents build reputations to overcome the difficulties that this institutional failure causes in a context of incomplete information. The model describes the interplay between...

We develop a new general equilibrium model of monopolistic competition with heterogeneous firms, variable demand elasticity and multiple asymmetric regions, in which trade integration induces wage and productivity changes. Using Canada-US interregional trade data, we structurally estimate a...

This paper reviews the new approach to international trade based on firm heterogeneity in differentiated product markets. This approach explains a variety of features exhibited in disaggregated trade data, including the higher productivity of exporters relative to non-exporters, within-industry...

Using a novel dataset with transactions level exports data from four African countries (Malawi, Mali, Senegal and Tanzania), this paper uncovers evidence of a high degree of experimentation at the extensive margin associated with low survival rates, consistent with high and middle income country...

Firms face competing needs to expand product variety and reduce production costs. Trade policy affects firm investments in product variety and production processes differently. Access to larger markets enables innovation to reduce costs. Although firm scale increases, foreign competition reduces...
