This paper investigates the elusive role of productivity heterogeneity in new trade models in the trade and environment nexus. We contrast the Eaton-Kortum and the Melitz models with firm heterogeneity to the Armington and Krugman models without heterogeneity. We show that if firms have a...

Carbon tariffs are one prominently discussed environmental policy. The proponents stress the carbon tariffs' ability to mitigate the potential negative effect of environmental-friendly production on competitiveness, to avoid carbon leakage and to reduce world carbon emissions. We analyze the...

Recent work on the effects of currency unions (CUs) on trade stresses the importance of using many countries and years in order to obtain reliable estimates. However, for large samples, computational issues limit choice of estimator, leaving an important methodological gap. To address this gap,...

In view of the deferred start of negotiations for the modernization of the Customs Union between the EU and Turkey (CU-EUT), we look back and analyse the ex post trade consequences of the CU-EUT. Employing up-to-date econometric best practices for regional integration agreements, we quantify...

The extensive margin of bilateral trade exhibits a high level of persistence that cannot be explained by geography or trade policy. We combine a heterogeneous firms model of international trade with bounded productivity with features from the firm dynamics literature to derive expressions for an...

Zunehmend setzen Staaten auf Allianzen oder Koalitionen, um gemeinsam Sanktionen gegen ein Drittland zu verhängen. Die Auswirkungen einer solchen Koordination sind jedoch unklar. Dieser Wochenbericht analysiert die Sanktionswelle gegen Russland im Jahr 2014 anhand von 400000 Simulationen mit...

How do exporting firms react to sanctions? Specifically, which firms are willing - or capable - to serve the market of a sanctioned country? We investigate this question for four sanctions episodes drawing on recent econometric advances in bias-corrected dynamic high-dimensional fixed effects...

Damit die EU ihre ambitionierten Klimaschutzziele erreichen kann, werden die Preise für Treibhausgasemissionen in den nächsten Jahren spürbar steigen. Das hat ökonomische Auswirkungen für die EU-Mitgliedsländer, aber auch den Rest der Welt. Einzelne Sektoren und auch Volkswirtschaften...

While international trade can offer gains from specialization and access to a wider range of products, it is also closely interlinked with global environmental problems, above all, anthropogenic climate change. This survey provides a structured overview of the economic literature on the...
