Abstract
Das neoklassische Wachstumsmodell von Solow aus dem Jahr 1956 gehört heute immer noch zu den wichtigsten Wachstumstheorien. Die heute gelehrten Formen, die sich in nahezu allen volkswirtschaftlichen Lehrbüchern befinden, verletzen jedoch einen wichtigen Zusammenhang aus der volkswirtschaftlichen Gesamtrechnung: die Identität von Nettoinvestitionen und Ersparnis. Die Lösungen der Lehrbuchmodelle widersprechen damit der ursprünglichen Solow-Lösung. Der vorliegende Beitrag zeigt die Konsequenzen dieser Ungenauigkeiten auf. Darüber hinaus wird ein Modell präsentiert, das die Identität von Nettoinvestitionen und Ersparnis wahrt und folglich mit der Solow-Lösung vereinbar ist.

Forum der Forschung. Wissenschaftsmagazin der Brandenburgischen Technischen Universität Cottbus,
No. 17,
2004
Abstract
The Government of the State of Brandenburg subsidised the company CargoLifter AG on the basis of the „new industrial policy“. Following this policy the government supports individually selected industries or companies. The „new industrial policy“ is supported by the strategic trade policy, which states that subsidising domestic companies in incomplete markets with declining average costs and high entry barriers can increase the welfare level of a particular region. The following article provides an analysis whether in the case of Cargo-Lifter the Government of the State of Brandenburg pursued an effective strategic trade policy. Moreover the article investigates particular problems of the strategic trade policy.

Under which conditions do inland suppliers profit from foreign direct investment?

Wirtschaft im Wandel,
No. 10,

Abstract
Aus theoretischer Sicht ergeben sich durch die Präsenz ausländischer Unternehmen nicht nur realwirtschaftliche Effekte auf Produktion und Beschäftigung, sondern auch ein Potential für technologische Entwicklung durch Wissenstransfer zu einheimischen Unternehmen. Dieser Wissenstransfer ist abhängig von dem Grad der Verflechtung des ausländischen Unternehmens mit der einheimischen Wirtschaft. Dabei kommt der Beziehung zwischen Investor und einheimischen Zulieferunternehmen eine zentrale Bedeutung zu, denn multinationale Unternehmen haben ein strategisches Interesse, alle lokalen Effizienzvorteile auszuschöpfen. Der vorliegende Beitrag unterstellt, daß sowohl die Ausbildung von Zulieferbeziehungen als auch das Potential für Wissenstransfer zum einen von organisatorischen Faktoren im ausländischen Unternehmen und zum anderen von der lokalen Wissensbasis und der technologischen Leistungsfähigkeit abhängig sind. Dieser Zusammenhang wird an Hand eines Datensatzes von 434 Tochterunternehmen aus fünf Mittel- und Osteuropäischen Ländern getestet. Die Ergebnisse zeigen, daß die Intensität von Zulieferbeziehungen als auch das Potential für Wissenstransfer steigt, wenn Tochterunternehmen als Joint Venture geführt werden sowie Eigenverantwortung in den Bereichen Logistik und Zulieferung besitzen. Die technologische Leistungsfähigkeit des heimischen Sektors fördert sowohl die Intensität von Zulieferbeziehungen als auch das Potential für Wissenstransfer. Zusätzlich steigert die absorptive Kapazität der einheimischen Zulieferbetriebe das Potential für Wissenstransfer. Will man verhindern, daß ausländische Investitionen auf einer „Insel“ inmitten der einheimischen Wirtschaft operieren und keine Wissenseffekte generieren, dann bietet die Förderung von Forschungs- und Entwicklungskooperationen zwischen ausländischen Investoren und lokalen Zulieferbetrieben in technologisch leistungsfähigen Sektoren ein opportunes Mittel.

Can EU Policy Intervention Help Productivity Catch-Up?
Johannes Stephan, P. Holmes, J. Lopez-Gonzales, C. Stolberg
Closing the EU East-West Productivity Gap - Foreign direct Investment, Competitiveness, and Public Policy,
2006
Abstract
"A product of the Framework V research project, this book addresses one of the key problems facing the EU today: Why is the ‘new’ EU so much poorer than the ‘old’, and how will EU enlargement help to solve the problem? Focusing on the productivity problems underlying the East-West gap, it looks in particular at the role that foreign investment and R&D can play in closing it. Against that background, the book assesses what role proactive development policy might play in attacking the roots of low social productivity. Concluding that there will be a clear-cut process of convergence between East and West, albeit an incomplete one, it finishes with an assessment of the patterns of competitiveness, East and West, that are likely to emerge from this process of incomplete convergence."

The IWH signals approach: the present potential for a financial crisis in selected Central and East European countries and Turkey

Wirtschaft im Wandel,
No. 8,
2006
Abstract
The steep increase of oil prices, general threats rooting from Iran’s nuclear program, and doubts about the future policy of important central banks recently caused more uncertainties of investors on international financial markets. This explains the higher volatility and the fall of indices on stock markets including those of some Central and East European countries. International investors could respond with adjustments of their portfolio and trigger off a financial crisis. On this background, the article studies the potential for a financial crises in the region mentioned. The analytical tool is the IWH signals approach. The study concludes that the risk of the outbreak of a financial crisis within the next 18 months is rather unrealistic in most countries. A stable economic policy, high real growth rates, a financial system already robust compared to earlier times of transition, and appropriate exchange rate arrangements protect the countries against speculative attacks and portfolio adjustments. When the composite indicator shows deterioration like in the Baltic countries, it turned out to be negligible. For the Slovak Republic and Slovenia, the composite indicator even improved. A closer look to individual indicators reveals still some problems in the banking sectors of the Czech Republic, Poland, and Hungary, however, without out major impact on the composite indicator.
This general assessment does not apply to Romania, and, in particular, to Turkey. The composite indicator signals a significant increase of the risk potential for the next 18 months in both countries. There is a considerable need for sound policy action.

Excess Volatility in European Equity Style Indices - New Evidence
Marian Berneburg
IWH Discussion Papers,
No. 16,
2006
Abstract
Are financial markets efficient? One proposition that seems to contradict this is Shiller’s finding of excess volatility in asset prices and its resulting rejection of the discounted cash flow model. This paper replicates Shiller’s approach for a different data set and extends his analysis by testing for a long-run relationship by means of a cointegration analysis. Contrary to previous studies, monthly data for an integrated European stock market is being used, with special attention to equity style investment strategies. On the basis of this analysis’ results, Shiller’s findings seem questionable. While a long-run relationship between prices and dividends can be observed for all equity styles, a certain degree, but to a much smaller extent than in Shiller’s approach, of excess volatility cannot be rejected. But it seems that a further relaxation of Shiller’s assumptions would completely eliminate the finding of an overly strong reaction of prices to changes in dividends. Two interesting side results are, that all three investment styles seem to have equal performance when adjusting for risk, which by itself is an indication for efficiency and that market participants seem to use current dividend payments from one company as an indication for future dividend payments by other firms. Overall the results of this paper lead to the conclusion that efficiency cannot be rejected for an integrated European equity market.

Direktinvestitionen in der Zwischenkriegszeit und nach 1990 - erste Ergebnisse eines nicht ganz einfachen Vergleichs

2006
Abstract
Foreign direct investments have a long tradition in Central East European countries and reached a considerable level already during the interwar period. From an economic point of view, Central Eastern Europe strongly depends on foreign investments - today like in the interwar period. Technological backwardness and a lack of internal sources of capital hampered the development of a self-sufficient economy in the newly founded states of Central Eastern Europe after the First World War as well as after the breakdown of socialism. Nevertheless, foreign direct investment has always been subject to a critical debate too in the host economies. Focusing on a comparison between Poland, Czechoslovakia/Czech Republic, and Hungary, the book deals with the continuities and changes of foreign direct investments in Central Eastern Europe - an issue that has been widely neglected in historical research so far.

Who Invests in Training if Contracts are Temporary? - Empirical Evidence for Germany Using Selection Correction
Jan Sauermann
IWH Discussion Papers,
No. 14,
2006
Abstract
This study deals with the effect of fixed-term contracts on work-related training. Though previous studies found a negative effect of fixed-term contracts on the participation in training, from the theoretical point of view it is not clear whether workers with fixed-term contracts receive less or more training, compared to workers with permanent contracts. In addition to the existing strand of literature, we especially distinguish between employer- and employee-financed training in order to allow for diverging investment patterns of worker and firm. Using data from the German Socio-Economic Panel (GSOEP), we estimate a bivariate probit model to control for selection effects that may arise from unobservable factors, affecting both participation in training and holding fixed-term contracts. Finding negative effects for employer-sponsored, as well as for employee-sponsored training, leads us to conclude that workers with fixed-term contracts do not compensate for lower firm investments.

Vertical Intra-industry Trade between EU and Accession Countries
Hubert Gabrisch
IWH Discussion Papers,
No. 12,
2006
Abstract
The paper analyses vertical intra-industry trade between EU and Accession countries, and concentrates on two country-specific determinants: Differences in personal income distribution and in technology. Both determinants have a strong link to national policies and to cross-border investment flows. In contrast to most other studies, income distribution is not seen as time-invariant variable, but as changing over time. What is new is also that differences in technology are tested in comparison with cost advantages from capital/labour ratios. The study applies panel estimation techniques with GLS. Results show country-pair fixed effects to be of high relevance for explaining vertical intraindustry trade. In addition, bilateral differences in personal income distribution and their changes are positive related to vertical intra-industry trade in this special regional integration framework; hence, distributional effects of policies matter. Also, technology differences turn out to be positively correlated with vertical intra-industry trade. However, the cost variable (here: relative GDP per capita) shows no clear picture, particularly not in combination with the technology variable.
