This paper examines data on trade flows between West German Bundeslander (federal states) and East Germany to explore the effect of national borders on trade. Although the data covers only a small fraction of intra-German trade flows, I find a home bias of about factor 2.2; West German shipments...

Mit den ökonomischen Unterschieden zwischen Ost- und Westdeutschland geht eine hohe Arbeitskräftemobilität einher. Auf das Pendeln entfällt ein bedeutender Anteil dieser Arbeitskräftemobilität. In der vorliegenden Dissertation werden die Determinanten und Auswirkungen des Pendelns zwischen...

We present a gravity model that accounts for multilateral resistance, firm heterogeneity and country-selectioninto trade, while accommodating asymmetries in trade flows. A new equation for the proportion of exporting…firms takes a gravity form: the extensive margin is also accected by...

Trade policy barriers are only one element of overall trade costs. Among these, and due to the decrease in the influence of tariff barriers on trade over time, institutional barriers might increase in relative importance and become a key obstacle to the movements of goods across countries. This...

This paper examines the involvement of the CEECs into regional and global production networks over the period 1999 to 2009. We employ a theoretically justified gravity model which incorporates the extensive margin of trade and accounts for firm heterogeneity. We first estimate the model for...

This paper deals with the quantification of GMO regulations on bilateral trade flows. A composite index of the complexity of such regulations for sixty countries as well as an objective score for six GMO regulatory sub-dimensions has been developed. Using a gravity model, we show how bilateral...
