Die deutsche Volkwirtschaft ist seit 1990 deutlich offener geworden. Der Anteil der Exporte am BIP hat sich zwischen 1990 und 2016 von 20% auf 46% und jener der Importe von 20% auf 38% erhöht. Die heimische Wertschöpfung, die hinter Güter- und Dienstleistungsexporten steckt, hat sich auf 32%...

We sort out confounding factors in the empirical link between bilateral migration and trade. Using newly available panel data on developing countries' diaspora to rich OECD nations in a theory-grounded gravity model, we uncover a robust, causal pro-trade effect. Moreover, we do not find evidence...

Trade economists traditionally study the effect of lower variable trade costs. While increasingly important politically, technical barriers to trade (TBTs) have received less attention. Viewing TBTs as fixed regulatory costs related to the entry into export markets, we use a model with...

Increasing-returns-to-scale imperfect competition trade models predict a more than proportionate relationship between the larger country’s share in world endowments and its share in producing firms: the so called home market effect (HME). While this result plays a key role in empirical...

This paper characterizes analytically the optimal tariff of a large one-sector economy with monopolistic competition and firm heterogeneity in general equilibrium, thereby extending the small-country results of Demidova and Rodriguez-Clare (JIE, 2009) and the homogeneous firms framework of Gros...

The business literature suggests that exporters either use trade intermediaries or own foreign sales representations. Standard trade models are silent about this choice. We develop a model where producers differ with respect to competitive advantage and where trade intermediaries arise...

The business literature and recent descriptive evidence show that exporting firms typically require the help of foreign trade intermediaries or need to set up own foreign wholesale affiliates. In contrast, conventional trade theory models assume that producers can directly access foreign...
