Abstract [en]

This paper uses a tailor-made new data set of 3,390,871 observations for German exports to non-EU countries at the firm-product-destination level in 2011 to investigate the link between the amount of firms' exports and the difference in time zones between Germany and the destination countries. The results indicate that including firm and product level heterogeneity is important. When distance to destination countries is controlled for, time zones only decrease exports for smaller exporters and for intermediate goods. The quantity of exports declines with increasing time difference within a firm for a given product for exports to the West (where time difference to Germany is negative) but not the East.

Abstract [en]

This paper uses information on more than 160 million export and import transactions by German firms from 2009 to 2012 to document the decisive role of multi-market traders that are active on many foreign markets, where a market is defined as a combination of a good traded and a country traded with. Using merged information from trade transactions and from surveys conducted by the statistical offices it is shown that, controlling for detailed industry affiliation, the number of foreign markets a firm from manufacturing industries is active on as an exporter or importer is higher in firms that are larger, older and foreign owned and that have higher labor productivity, human capital intensity and R&D intensity. With the exception of labor productivity these results are valid ceteris paribus, too. All these results from a descriptive empirical investigation are in line with hypotheses that are derived from the literature on the links between firm characteristics and the extensive margins of foreign trade.

Abstract [en]

This paper uses information on import transactions by German firms from 2009 to 2012 merged with information on characteristics of the importers taken from surveys by the Statistical Offices to document that a large share of importers engage in multiple import sourcing by importing the same good from more than one source country in a year and that a large share of total imports is due to multiple sourcing. It is shown that the probability of multiple import sourcing and the share of imports from multiple sourcing in total imports increase with firm productivity and firm size after controlling for detailed industry affiliation.

Abstract [en]

This paper uses information on all export transactions of goods by German firms with countries outside the European Union from 2009 to 2014 to document for the first time the patterns of export participation at the firm-good-destination level over time and to investigate the link between the duration of export patterns and characteristics of destination countries. It turns out that only 6.5 percent of all combinations were recorded in each year, while more than half of all patterns are only observed once. In line with theoretical hypotheses, the likelihood of permanent trade patterns increases within a firm with proximity and market size of destination countries.

Abstract [en]

This article uses a tailor-made new data set of 7 580 251 observations for German exports at the firm-product-destination level to estimate a gravity equation and to investigate the link between the amount of firms’ exports and the distance to destination countries. It is shown that, in line with stylized facts based on aggregate data, the quantity of exports declines significantly with distance within a firm for a given product.

Abstract [en]

This paper uses a tailor-made new data set of 7,112,614 observations for export quality (measured by the unit value of exports) at the firm-product-destination level for German and the reporting year 2011. Data are from 119,280 firms that exported 4986 products (recorded at the HS6-level) in 1,632,731 firm-product combinations to 174 countries. The paper investigates for the first time the link between the quality of firms' exports and the distance to destination countries for Germany. It is shown that, in line with theory, the quality of exported goods and distance to destination countries are statistically positively correlated.

Abstract [en]

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 firms outperform East German firms at all four margins of exports - they have a larger propensity to export, export a larger share of total sales, export more goods and export to a larger number of countries. All these differences are large from an economic point of view. A decomposition analysis shows that in 2010 between 59 percent and 78 percent of the difference in margins can be explained by differences in firm characteristics.

Abstract [en]

This article uses a new tailor-made data set to investigate the link between firm age and the extensive margins of imports empirically for the first time for Germany. Results turn out to be fully in line with the theoretical considerations. Older firms are more often importers, import more different goods, and import from more different countries of origin.

Abstract [en]

With this article we present the first microeconometric analysis of the impact of a foreign acquisition on the target firm's access to finance. By using a large database of German firms, we furthermore investigate for the first time the link between foreign ownership and access to finance in Germany, one of the world's leading target countries for FDI. We use newly available comprehensive panel data that we constructed from information collected by the German statistical offices and from credit rating scores supplied by the leading German credit rating agency. We find foreign-owned firms in German manufacturing on average to show slightly more financing restrictions than domestically owned enterprises, but this very small difference diminishes once unobserved heterogeneity is taken into account. We further demonstrate that one reason for this finding is the preference of foreign investors for targets with relatively low creditworthiness. Although the likelihood of a foreign acquisition appears to be correlated with credit rating, there is no impact of foreign takeovers on the credit constraints of the target firms ex post and therefore no support for the hypothesis that foreign takeovers ease financial frictions.
