Bottom-up or Direct? Forecasting German GDP in a Data-rich Environment
Katja Drechsel, Rolf Scheufele
Abstract
This paper presents a method to conduct early estimates of GDP growth in Germany. We employ MIDAS regressions to circumvent the mixed frequency problem and use pooling techniques to summarize efficiently the information content of the various indicators. More specifically, we investigate whether it is better to disaggregate GDP (either via total value added of each sector or by the expenditure side) or whether a direct approach is more appropriate when it comes to forecasting GDP growth. Our approach combines a large set of monthly and quarterly coincident and leading indicators and takes into account the respective publication delay.

The Causal Effect of Watching TV on Material Aspirations: Evidence from the “Valley of the Innocent”
Walter Hyll, Lutz Schneider
Journal of Economic Behavior and Organization,
Nr. 86,
2013
Abstract
The paper addresses the question of whether TV consumption has an impact on material aspirations. We exploit a natural experiment that took place during the period in which Germany was divided. Owing to geographical reasons TV programs from the Federal Republic of Germany could not be received in all parts of the German Democratic Republic. Therefore a natural variation occurred in exposure to West German television. We find robust evidence that watching TV is positively correlated with aspirations. Our identification strategy implies a causal relationship running from TV to aspirations. This conclusion resists various sets of alternative specifications and samples.

FDI and Domestic Investment: An Industry-level View
Claudia M. Buch
CEPR. Discussion Paper No. 6464,
2007
Abstract
Previous empirical work on the link between domestic and foreign investment provides mixed results which partly depend on the level of aggregation of the data. We argue that the aggregated home country implications of foreign direct investment (FDI) cannot be gauged using firm-level data. Aggregated data, in turn, miss channels through which domestic and foreign activities interact. Instead, industry-level data provide useful information on the link between domestic and foreign investment. We theoretically show that the effects of FDI on the domestic capital stock depend on the structure of industries and the relative importance of domestic and multinational firms. Our model allows distinguishing intra-sector competition from inter-sector linkage effects. We test the model using data on German FDI. Using panel cointegration methods, we find evidence for a positive long-run impact of FDI on the domestic capital stock and on the stock of inward FDI. Effects of FDI on the domestic capital stock are driven mainly by intra-sector effects. For inward FDI, inter-sector linkages matter as well.

FDI and Domestic Investment: An Industry-level View

Abstract
Previous empirical work on the link between domestic and foreign investment has provided mixed results. This may partly be due to the level of aggregation of the data. In this paper, we argue that the impact of FDI on the domestic capital stock depends on the structure of industries. Using industry-level data on the stock of German FDI, we test our predictions. We use panel cointegration methods which address the potential endogeneity of FDI. We find evidence for a positive long-run impact of FDI on the domestic capital stock.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Annals of Regional Science,
Nr. 1,
2010
Abstract
This study analyzes the relationship between the specialization of a region in certain industries and the efficiency of the region in generating new knowledge. The efficiency measure is constructed by relating regional R&D input and output. An inversely u-shaped relationship is found between regional specialization and R&D efficiency, indicating the presence of externalities of both Marshall and Jacobs’ type. Further factors influencing efficiency are externalities resulting from high R&D intensity of the local private sector as well as knowledge from local public research institutions. The impact of both the specialization and the additional factors is, however, different for regions at different efficiency levels.

International Bank Portfolios: Short- and Long-run Responses to Macroeconomic Conditions
S. Blank, Claudia M. Buch
Review of International Economics,
Nr. 2,
2010
Abstract
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.

Is East Germany Catching Up? A Time Series Perspective
Bernd Aumann, Rolf Scheufele
Post-Communist Economies,
2010
Abstract
This article assesses whether the economy of East Germany is catching up with the West German region in terms of welfare. While the primary measure for convergence and catching up is per capita output, we also look at other macroeconomic indicators such as unemployment rates, wage rates and production levels in the manufacturing sector. In contrast to existing studies of convergence between regions of the reunified Germany, our approach is based purely upon the time series dimension and is thus directly focused on the catching up process in East Germany as a region. Our testing set-up includes standard ADF unit root tests as well as unit root tests that endogenously allow for a break in the deterministic component of the process. We find evidence of catching up for East Germany for most of the indicators. However, the convergence speed is slow, and thus it can be expected that the catching up process will take further decades until the regional gap is closed.

Cross-border Diversification in Bank Asset Portfolios

Abstract
We compute optimally diversified international asset portfolios for banks located in France, Germany, Italy, the United Kingdom and the United States using the mean–variance portfolio model with currency hedging. We compare these benchmark portfolios with the actual cross-border asset positions of banks from 1995 to 2003 and ask whether the differences are best explained by regulations, institutions, cultural conditions or other financial frictions. Our results suggest that both culture and regulations affect the probability of a country's being overweighted in banks' portfolios: countries whose residents score higher on a survey measure of trust are more likely to be overweighted, while countries that have tighter capital controls are less likely to be overweighted. From a policy standpoint, the importance of culture suggests a limit to the degree of financial integration that may be achievable by the removal of formal economic barriers.

Von der Intention zur Gründung - Gründerwettbewerbe in Deutschland

List Forum für Wirtschafts- und Finanzpolitik,
Nr. 4,
2010
Abstract
Die Realisierung von positiven Effekten technologieorientierter Existenzgründungen wird in vielen Fällen dadurch unterbunden, dass Unternehmensgründungen speziell in diesen Wirtschaftszweigen zwar geplant, aber zu selten tatsächlich umgesetzt werden. Um angehenden Unternehmensgründern den Schritt von der Intention hin zur tatsächlichen Umsetzung der Gründungsidee am Markt zu erleichtern, haben sich seit Mitte der 1990er Jahre vielfältige Gründerwettbewerbe etabliert. Gründerwettbewerbe sind im Kontext potentieller Gründer das wohl wichtigste Förderinstrument. Sie setzen an wesentlichen Aspekten einer geplanten Unternehmensgründung an und tragen zur kritischen Beurteilung und Verbesserung geplanter Geschäftskonzepte bei. Gegenwärtig können 61 Gründerwettbewerbe in Deutschland identifiziert werden. Ungeachtet ihrer Bedeutung in der Gründungspraxis wird sich bislang kaum damit auseinandergesetzt. Insbesondere zum Aspekt, inwiefern Gründerwettbewerbe potentiellen Unternehmensgründern signifikante Unterstützung zur langfristig erfolgreichen Umsetzung ihres Geschäftsmodells im Markt leisten, liegen gegenwärtig kaum belastbare Erkenntnisse vor. Der vorliegende Beitrag greift diese Themenstellung auf und legt erste Ergebnisse einer umfassenden Erhebung von Gründerwettbewerben in Deutschland vor, zeigt deren Entwicklung im Zeitablauf sowie die regionale Verteilung und stellt Auswertungen zu zentralen Wettbewerbscharakteristika dar. Darauf aufbauend erfolgt eine kritische Diskussion der wichtigsten, noch unbeantworteten, Fragen zur Beurteilung der Effektivität von Gründerwettbewerben, insbesondere im Hinblick auf ihren potentiellen Beitrag, eine geplante Unternehmensgründung auch tatsächlich umzusetzen.
