This paper uses a new tailor-made data set to investigate the differences in extensive and intensive margins of exports in manufacturing firms from East Germany and West Germany. It documents that these margins do still differ in 2010, 20 years after the re-unification of Germany. West German...

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...

I investigate the relationship between the extensive margins of imports and exports (the number of countries traded with and the number of goods traded) and firm productivity using a newly constructed and rich panel data set of German manufacturing firms for the years 2009-2014. I do for the...

Why do borders still matter for economic activity? The reunification of Germany in 1990 provides a unique natural experiment for examining the effect of political borders on trade both in the cross-section and over time. With the fall of the Berlin Wall and the rapid formation of a political and...

Using unique new data and a recently introduced non-linear decomposition technique this paper shows that the huge difference in the propensity to export between West and East German plants is to a large part due to differences in firm size and human capital intensity

This paper explores the effects of economic integration on intensive and extensive export margins of Nigeria's trade with ECOWAS and other African countries. Multiple indices of economic integration and the margins of exports are computed. Fractional Logit model is used to estimate the intensive...

Recent empirical research in international trade emphasizes the role of the extensive and intensive margin to the export growth. This paper examines the sources of export growth in Turkey. For this purpose, the study decomposes Turkey's export growth into extensive and intensive margins by using...
