China's accession to the World Trade Organization (WTO) in 2001 was a massive boostfor the multilateral trading system. We present descriptive evidence on the trade effects of China's WTO accession. Moreover, we combine the most recent approaches from the gravity literature of international...

In this paper, we provide a detailed analysis of a mechanism that distorts production towards too much use of primary factors like labor and too little use of intermediate inputs. The distortion results from two ingredients that are cornerstones of modern quantitative trade theory: monopolistic...

In this paper, we zoom in on the firm level of German merchandise foreign trade, using a novel data base with information on the export and import value by firm, country, product and year for the period 2011-2019. Problems arising from the consolidated reporting of taxable entities and the...

Vor 200 Jahren hat einer der Gründungsväter der modernen Volkswirtschaftslehre, David Ricardo, in seinem Buch Principles of Political Economy and Taxation die Theorie der komparativen Vorteile vorgestellt. Vom Abbau von Handelsbarrieren profitieren alle Länder, sogar die, die im Vergleich zu...

Die deutsche Volkswirtschaft ist seit 1990 durch den Fall des Eisernen Vorhangs, den Beitritt von 16 neuen Mitgliedern in die EU, den Aufstieg und WTO-Beitritt Chinas, die Einführung des Euro, die Schaffung des Schengen-Raums und den Abschluss verschiedener Freihandelsabkommen der EU mit...

In New Trade Theory models, the larger region hosts an overproportionate share of producers. This Home Market Effect (HME) exacerbates regional income discrepancies caused by trade frictions or technology differences. With homogeneous firms, it requires inter-industry reallocations to emerge. We...

Member countries of a currency union like the euro area have absorbed asymmetric shocks in ways that are inconsistent with a common nominal anchor. Based on a reformulation of the gravity model that allows for such bilateral misalignment, we disentangle the conventional microeconomic trade...

Arkolakis, Costinot and Rodriguez-Clare (ACR, 2012) prove that, conditional on the change in openness, the welfare gains from foreign trade reforms are quantitatively identical across single-sector trade models with radically different micro-foundations. We generalize this result to domestic and...
