International bank portfolios constitute a large component of international country portfolios. Yet, banks’ response to international macroeconomic conditions remains largely unexplored.We use a novel dataset on banks’ international portfolios to answer three questions. First, what are the long-run determinants of banks’ international portfolios? Second, how do banks’ international portfolios adjust to short-run macroeconomic developments? Third, does the speed of adjustment change with the degree of financial integration?We find that, in the long-run, market size has a positive impact on foreign assets and liabilities. An increase in the interest differential between the home and the foreign economy lowers foreign assets and increases foreign liabilities. Foreign trade has a positive impact on international bank portfolios, which is independent from the effect of other macroeconomic variables. Short-run dynamics show heterogeneity across countries, but these dynamics can partly be explained with gravity-type variables.

We discuss how the welfare ranking of fixed and flexible exchange rate regimes in a New Open Economy Macroeconomics model depends on the interplay between the degree of exchange rate pass-through and the elasticity of substitution between home and foreign goods. We identify combinations of these two parameters for which flexible and fixed exchange rates are superior with respect to welfare as measured by a representative household's utility level. We estimate the two parameters for six non-EMU European countries (Czech Republic, Hungary, Poland, Slovakia, Sweden, and the UK) using a heterogeneous dynamic panel approach.

In this paper we develop a small open economy model explaining the joint determination of output, inflation, interest rates, unemployment and the exchange rate in a multi-country framework. Our model – the Halle Economic Projection Model (HEPM) – is closely related to studies recently published by the International

Monetary Fund (global projection model). Our main contribution is that we model the Euro area countries separately. In this version we consider Germany and France, which represent together about 50 percent of Euro area GDP. The model allows for country specific heterogeneity in the sense that we capture different adjustment patterns to economic shocks. The model is estimated using Bayesian techniques. Out-of-sample and pseudo out-of-sample forecasts are presented.

This paper explores the impact of financial constraints on the internationalization

strategies of firms. It contributes to the literature by focusing on three aspects: First, the paper studies the impact of financial constraints on exporting relative to FDI. Consistent with theory, the empirical results confirm that the impact of financial constraints is stronger for FDI than for exporting. Second, the paper analyzes the extensive and the intensive margins and finds that financial frictions matter for both. Third, the paper explores the impact on manufacturing as compared to service industries and shows that firms in service industries are affected more than firms in manufacturing. The paper also identifies a threshold effect: Financial constraints do not matter for small firms whose productivity seems to be too low to consider international expansions.

While the long run relation between money and inflation is well established, empirical evidence on the adjustment to the long run equilibrium is very heterogeneous. In the present paper we use a multivariate state space framework, that substantially expands the traditional vector error correction approach, to analyze the short run impact of money on prices. We contribute to the literature in three ways: First, we distinguish changes in velocity of money that are due to institutional developments and thus do not induce inflationary pressure, and changes that reflect transitory movements in money demand. This is achieved with a newly developed multivariate unobserved components decomposition. Second, we analyze whether the high volatility of the transmission from monetary pressure to inflation follows some structure, i.e., if the parameter regime can assumed to be constant. Finally, we use our model to illustrate the consequences of the monetary policy of the Fed that has been employed to mitigate the impact of the financial crisis, simulating different exit strategy scenarios.

Seit Mitte der 1990er Jahre haben sich die deutschen Arbeitsmarktregionen sehr heterogen entwickelt. So existieren Regionen, die neben einer Steigerung ihrer Wettbewerbsfähigkeit zusätzlich einen Erwerbstätigenzuwachs verzeichnen konnten. Daneben sind Regionen zu finden, deren wirtschaftliches Wachstum und deren Arbeitsplatzentwicklung ungünstiger verliefen. Diese Beobachtung führt mit Blick auf regionalpolitische Förderziele und Strategien zu weitreichenden Konsequenzen.

Recent literature on multinational firms has stressed the importance of low productivity as a barrier to the cross-border expansion of firms. But firms may also need external finance to shoulder the costs of entering foreign markets. We develop a model of multinational firms facing real and financial barriers to foreign direct investment (FDI), and we analyze their impact on the FDI decision (the extensive margin) and foreign affiliate sales (the intensive margin). We provide empirical evidence based on a detailed dataset of German multinationals which contains information on parent-level and affiliate-level financial constraints as well as about the location the foreign affiliates. We find that financial factors constrain firms’ foreign investment decisions, an effect felt in particular by large firms. Financial constraints at the parent level matter for the extensive, but less

so for the intensive margin. For the intensive margin, financial constraints at the affiliate level are relatively more important.

Exporters and multinationals are larger and more productive than their domestic

counterparts. In addition to productivity, financial constraints and labor market

constraints might constitute barriers to entry into foreign markets. We present new

empirical evidence on the extensive and intensive margin of exports and FDI based on detailed micro-level data of German firms. Our paper has three main findings. First, in line with earlier literature, we find a positive impact of firm size and productivity on firms’ international activities. Second, small firms suffer more frequently from financial constraints than bigger firms, but financial conditions have no strong effect on internationalization. Third, labor market constraints constitute a more severe barrier to foreign activities than financial constraints. Being covered by collective bargaining particularly impedes international activities.

With regard to the survival rates of business incubator (BI) firms, the literature mainly presents findings of failure rates only during the incubation period. Little is known about the survival or exit dynamics of firms after leaving the incubator facilities. The study approaches this research question by examining the survival of 352 firms from five German BIs after their graduation. The findings suggest that graduation causes an immediate negative effect on survivability that lasts up to three years after leaving the incubators. Furthermore, heterogeneous patterns of post-graduation exit dynamics between the BIs were observed. It was also found that performance during the incubation period is an indicator of the propensity of business closure after graduation. This study offers valuable insights and implications for all stakeholders of BI-initiatives.

Bank efficiency estimates often serve as a proxy of managerial skill since they quantify sub-optimal production choices. But such deviations can also be due to omitted systematic differences among banks. In this study, we examine the effects of heterogeneity on bank efficiency scores. We compare different specifications of a stochastic cost and alternative profit frontier model with a baseline specification. After conducting a specification test, we discuss heterogeneity effects on efficiency levels, ranks and the tails of the efficiency distribution. We find that heterogeneity controls influence both banks’ optimal costs and profits and their ability to be efficient. Differences in efficiency scores are important for more than only methodological reasons. First, different ways of accounting for heterogeneity result in estimates of foregone profits and additional costs that are significantly different from what we infer from our general specification. Second, banks are significantly re-ranked when their efficiency is estimated with a specification other than the preferred, general specification. Third, the general specification gives the most reliable estimates of the probability of distress, although differences to the other specifications are low.
