In this paper we use unit roots/cointegration analysis and time-varying parameters procedures to test for a common growth path in the ex-communist block, both pre- and post-reform. We test whether there has been convergence within the block and between the block as a group and the West....

We study patterns of FDI in a multi-country world economy. First, we present evidence for a broad sample of countries that firms direct FDI disproportionately to markets with income levels similar to their home market. Then we develop a model featuring non-homothetic preferences for quality and...

The basic gains-from-trade theorem makes a stark comparison between completely free trade and complete autarky. This paper is motivated by recent evidence that trade has greatly expanded on the extensive margin (aka fragmentation, offshoring) by adding newly traded goods and services and that...

This Paper looks at the impact of international vertical specialization when the final good industry is imperfectly competitive. Final goods are assembled out of different fragments. In the absence of international vertical specialization all fragments required to produce a given final good must...

This paper proposes a framework for gross exports accounting that breaks up a country’s gross exports into various value-added components by source and additional double counted terms. By identifying which parts of the official trade data are double counted and the sources of the double...

It is often alleged that PTAs involving the EC and the US include a significant number of obligations in areas not currently covered by the WTO Agreement, such as investment protection, competition policy, labour standards and environmental protection. The primary purpose of this study is...

We present new stylized facts on bank and firm leverage for 2000-2009 using extensive internationally comparable micro level data from several countries. The main result is that there was very little buildup in leverage for the average non-financial firm and commercial bank before the crisis,...

Inspired by the current debate over the future of the monetary union in Europe, this paper provides a simple model for the determination of the conditions of survival of the common good, which requires the creation of an effective fiscal union. We highlight the importance of institutional design...

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...

This paper develops a model of trade and CO2 emissions with heterogenous firms, where firms make abatement investments and thereby have an impact on their level of emissions. The model shows that investments in abatements are positively related to firm productivity and firm exports. Emission...
