Combining unique data bases on emissions with sectoral output and employment data, we study the sources of the fall in world-wide SO2 emissions and estimate the impact of trade on emissions. Contrarily to concerns raised by environmentalists, an emission-decomposition exercise shows that scale...

This paper employs worldwide data on output and bilateral trade in order to identify optimum currency areas (OCA’s) on a global basis. By retaining only two of the many criteria that have been mentioned in the literature on OCA’s, it has been possible to use computer programming to do the...

This paper explores the link between trade and European labour markets by using evidence on relative commodity prices and intra-sectoral skill levels at the NACE three-digit level for the four large EC countries and for the period 1976–90. We find that if the relative import prices of...

Paul Krugman has clarified the microeconomic underpinnings of both spatial economic agglomerations and regional imbalances at national and international levels. He has achieved this with a series of remarkably original papers and books that succeed in combining imperfect competition, increasing...

This paper investigates the role of the exchange rate regime in the process of trade adjustment, by examining the relationship between trade prices and exchange rate regimes. The theoretical framework is a dynamic one à la Froot-Klemperer (1989). The empirical investigation takes advantage of...

The majority of independent nations today were part of empires in 1945. Using bilateral trade data from 1948 to 2006, we examine the effect of independence on post-colonial trade. On average, there is little short run effect of trade with the colonizer (metropole). However, after three decades...

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...

We provide theoretical and empirical evidence that policy uncertainty can significantly affect firm level investment and entry decisions in the context of international trade. When market entry costs are sunk, policy uncertainty can create a real option value of waiting to enter foreign markets...

In this paper we explore the potential gains that a trade agreement (TA) can provide by regulating trade-policy uncertainty, in addition to the more standard gains from reducing the mean levels of trade barriers. We show that in a standard trade model with income-risk neutrality there tends to...
