New developments in the world economy have triggered research designed to better understand the changes in trade and investment patterns, and the reorganization of production across national borders. Although traditional trade theory has much to offer in explaining parts of this puzzle, other...

The increased integration of the economies of Central and Eastern Europe with the European Union (EU) as the Europe Agreements are progressively implemented, is projected to have a significant impact on trade flows with Spain, as exports and imports grow very rapidly, albeit starting from a very...

Trade theorists have come to understand that their theory is ambiguous on the question: are trade and factor flows substitutes? While this sounds like an open invitation for empirical research, hardly any serious econometric work has appeared in the literature. This paper uses history to fill...

Freshwater scarcity is bound to be a major challenge of the 21st century. Drawing on newly available data, I investigate to what extent countries make efficient use of the very uneven water resources on a global scale. In particular, I find that countries that are relatively water abundant tend...

This paper presents a dynamic North-South general- equilibrium model where households have non-homothetic preferences. Innovation takes place in a rich North while firms in a poor South imitate products manufactured in North. Introducing non-homothetic preferences delivers a complete...

This paper studies the trade of China in the past 150 years, starting from the first opening of China after the Opium War. The main purpose of the paper is to identify what is (and was) China’s ‘normal’ level of foreign trade, and how these levels changed under different trade regimes,...

I build a simple dynamic model of the formation of an international social network of importers and exporters. Firms can only export into markets in which they have a contact. They acquire new contacts both at random, and via their network of existing contacts. This model explains (i) the...

This paper examines the extent to which the destination of exports matters for the input prices paid by firms, using detailed customs and firm-product-level data from Portugal. We use exchange-rate movements as a source of variation in export destinations and find that exporting to richer...

This paper considers the locational choice of firms in an upstream and a downstream industry. Both industries are imperfectly competitive, with firms subject to increasing returns. There are transport costs between the two locations. Depending on the level of these costs there may be a single...

Increasingly, a small number of low-wage countries such as China and India are involved in innovation - not the `big ideas', but the constant incremental innovations needed to stay ahead in business. We provide some evidence of this and develop a model in which there is a transition from...
