Internationale Konvergenz sektoraler Produktionsniveaus

Nr. 20,
2005
Abstract
Die Frage, inwieweit sich die Wirtschaftskraft verschiedener Region langfristig aneinander annähert, ist unter wirtschaftstheoretischem wie wirtschaftspolitischem Gesichtspunkt von erheblichem Interesse. Aus Sicht der Wirtschaftstheorie, weil nur wenig bekannt ist über die Anpassungsmechanismen, die zur Konvergenz beitragen; aus Sicht der Wirtschaftspolitik, weil in westlichen Gesellschaften der Ausgleich regionaler Wohlfahrtsunterschiede eines der grundlegenden gesellschaftlichen Ziele darstellt. Die Arbeit von Gerald Müller fügt sich in diesen Rahmen ein, indem sie zum einen die unterschiedlichen Mechanismen von Konvergenzprozessen näher betrachtet, zum anderen auch sektorale Unterschiede herausarbeitet. Dabei kommt er zu Ergebnissen, die teilweise den gängigen (Vor)Urteilen widersprechen, so z. B. mit Blick auf die Bedeutung der Kapitalakkumulation für die Produktivitätsangleichung oder die sektoralen Muster von Konvergenzprozessen. Dies wirft wiederum ein neues Licht auf typische Politiken zur Beschleunigung und Beförderung von Konvergenzprozessen.

Länder-Rankings und internationale Wettbewerbsfähigkeit. Eine kritische Analyse

Abstract
Die Welt wird immer komplexer – entsprechend nimmt in der Öffentlichkeit die Nachfrage nach "Komplexitätsreduktion" zu. Allgemein zugängliche Datenangebote, moderne Statistik und Technik erlauben es, diese Nachfrage zu bedienen, und so überrascht es wenig, wenn in den letzten Jahren "Ranking-Vergleiche" aller Art an Verbreitung gewonnen haben. Aus theoretischer wie aus empirischer Sicht stellt sich freilich die Frage, ob und wie die Rankings die angestrebte Informationsverdichtung erreichen, ob tatsächlich das gemessen wird, was zu messen vorgegeben wird. Betrachtet man die entsprechenden Ergebnisse der Rankings in den letzten Jahren oder ihre Berechnungsschemata, treten Zweifel auf. Wie die Ergebnisse zeigen, ist die Aussagekraft dieser Rankings als sehr eingeschränkt anzusehen.

Abstract
In complex systems, statistical dependencies between individual components are often considered one of the key mechanisms which drive the system dynamics observed on a macroscopic level. In this paper, we study cross-sectional time-lagged dependencies in financial markets, quantified by nonparametric measures from information theory, and estimate directed temporal dependency networks in financial markets. We examine the emergence of strongly connected feedback components in the estimated networks, and hypothesize that the existence of information feedback in financial networks induces strong spatiotemporal spillover effects and thus indicates systemic risk. We obtain empirical results by applying our methodology on stock market and real estate data, and demonstrate that the estimated networks exhibit strongly connected components around periods of high volatility in the markets. To further study this phenomenon, we construct a systemic risk indicator based on the proposed approach, and show that it can be used to predict future market distress. Results from both the stock market and real estate data suggest that our approach can be useful in obtaining early-warning signals for crashes in financial markets.

Predicting the Rise of EU Right-Wing Populism in Response to Unbalanced Immigration

Abstract
Among the central tenets of globalization is the free migration of labor. Although much has been written about the benefits of globalization, little is known about its limitations and how antiglobalist sentiment can be strongly affected by high levels of immigration. Analyzing poll data from a group of EU countries affected by the recent migrant crisis, we find that over the last three years the percentage of right-wing (RW) populist voters in a given country depends on the prevalence of immigrants in this country’s population and the total immigration inflow into the entire EU. The latter is likely due to the perception that the EU functions as a supranational state in which a lack of inner borders means that “someone else’s problem” can easily become “my problem.” We find that the increase in the percentage of RW voters substantially surpasses the percentage of immigration inflow, implying that if this process continues, ongoing democratic processes will cause RW populism to prevail and globalization to rapidly decrease. We locate tipping points between the fraction of immigrants and the rise of RW populism, and we model our empirical findings using a complex network framework in which the success of globalization rests on a balance between immigration and immigrant integration.

Negotiated Third Party Access - an Industrial Organisation Perspective
Christian Growitsch, Thomas Wein
European Journal of Law and Economics,
2005
Abstract
In the course of the liberalization of European energy markets, the German government opted – diverging from all other European countries – for Negotiated Third-Party Access. In this article we analyze if, theoretically, this institutional regime can be superior to regulation. We review empirically whether certain aspects of the actual implementation, in particular publication of the network access charges for each network supplier, facilitated or inhibited competition. In the first place we reconsider previous research, showing that NTPA can – under certain conditions – be economically effective. Our empirical analysis shows that the duty of publishing access charges supported market transparency and imposed a regulatory threat, particularly to suppliers with significantly above-average charges. On the other hand observable price adjustments over time serve as an indicator of tacit collusion. Although the expensive suppliers cut their prices, the cheaper ones raised theirs.

Abstract
Die vorliegende Publikation analysiert Währungskrisen in Mittel- und Osteuropa. Es werden die Ergebnisse eines Forschungsprojekts wiedergegeben, welches das Institut für Wirtschaftsforschung Halle im Auftrag des Bundesministeriums der Finanzen durchgeführt hat. Im Rahmen dieses Projektes (ursprünglicher Titel: Leistungsbilanzentwicklung – Ursachen, Übertragung von Währungskrisen und wirtschaftspolitische Konsequenzen in mittel- und osteuropäischen Ländern) wurden die Gründe und die Tragbarkeit (sustainability) von Leistungsbilanzdefiziten untersucht; weiter wurde die Übertragung von Währungskrisen zwischen den Regionen überprüft; schließlich galt es Handlungsoptionen auszuloten, die zum Ziel haben, den Ausbruch oder die Übertragung einer Währungskrise zu verhindern.

Executive Compensation and Labor Expenses

Abstract
Using data on US public firms, I uncover a strong and positive correlation between executive compensationand labor expenses. On average, a 1% increase in the wage bill translates into a 0.3% raise in total executivepay. This association is driven by wages rather than by employment growth, is stronger for the incentive thanfor the salary component of executive compensation, and is particularly pronounced in the financial sector.

Do Conventional Monetary Policy Instruments Matter in Unconventional Times?

Journal of Banking and Finance,

Abstract
This paper investigates how declines in the deposit facility rate set by the ECB affect euro area banks’ incentives to hold reserves at the central bank. We find that, in the face of lower deposit rates, banks with a more interest-sensitive business model are more likely to reduce reserve holdings and allocate freed-up liquidity to loans. The result is driven by banks in the non-GIIPS countries of the euro area. This reveals that conventional monetary policy instruments have limited effects in restoring monetary policy transmission during times of crisis.

Interactions Between Bank Levies and Corporate Taxes: How is Bank Leverage Affected?

Journal of Banking and Finance,

2020
Abstract
Regulatory bank levies set incentives for banks to reduce leverage. At the same time, corporate income taxation makes funding through debt more attractive. In this paper, we explore how regulatory levies affect bank capital structure, depending on corporate income taxation. Based on bank balance sheet data from 2006 to 2014 for a panel of EU-banks, our analysis yields three main results: The introduction of bank levies leads to lower leverage as liabilities become more expensive. This effect is weaker the more elevated corporate income taxes are. In countries charging very high corporate income taxes, the incentives of bank levies to reduce leverage turn insignificant. Thus, bank levies can counteract the debt bias of taxation only partially.

Drawing Conclusions from Structural Vector Autoregressions Identified on the Basis of Sign Restrictions

Journal of International Money and Finance,
December
2020
Abstract
This paper discusses the problems associated with using information about the signs of certain magnitudes as a basis for drawing structural conclusions in vector autoregressions. We also review available tools to solve these problems. For illustration we use Dahlhaus and Vasishtha’s (2019) study of the effects of a U.S. monetary contraction on capital flows to emerging markets. We explain why sign restrictions alone are not enough to allow us to answer the question and suggest alternative approaches that could be used.
