Heterogeneity in size and productivity is central to models that explain which manufacturing firms export. This study presents descriptive evidence on similar heterogeneity among international banks as financial services providers. A novel and detailed bank-level data set reveals the volume and mode of international activities for all German banks. Only a few, large banks have a commercial presence abroad, consistent with the size pecking order documented for manufacturing firms. However, the relationship between internationalization and productivity also yields two inconsistencies with recent trade models. First, virtually all banks hold at least some foreign assets, irrespective of size or productivity. Second, some fairly unproductive banks maintain commercial presences abroad.

MotivationTo present descriptive evidence on the relationship between size, productivity, and the internationalization patterns of banks, we use a novel micro data set: the External Position Report (Auslandsstatus) provided by the German central bank, the Deutsche Bundesbank. Using data that cover all 2226 German banks' international exposures in 63 countries during the years 2002-2006, we explore a potentially important new data source for research in international trade in financial services. We ask if observed internationalization patterns of banks are consistent with the evidence previously presented for manufacturing firms.In manufacturing, larger and more productive firms are more likely to export and engage in foreign direct investment (FDI) than are smaller and less productive firms (Eaton et al., 2004;Helpman et al., 2004;Bernard et al., 2007;Lileeva and Trefler, 2010), due to the interaction between firm-level productivity and the costs of market entry (Melitz, 2003;Helpman et al., 2008): domestic fixed costs are lower than the fixed costs of exporting, which are lower than the fixed costs of FDI.1 Firms self-select into different modes of entry, because the higher fixed costs of more complex foreign activity modes require higher productivity, which results in a "pecking order of productivity". We distinguish the cross-border provision of financial services and commercial presences (branches or subs...
