The Importance of Localized Related Variety for International Diversification of Corporate Technology
Eva Dettmann, Iciar Dominguez Lacasa, Jutta Günther, Björn Jindra
Regional Studies,
Nr. 10,
2016
Abstract
Die Bedeutung der lokalisierten verbundenen Vielfalt für die internationale Diversifizierung von Unternehmenstechnik.
Die Internationalisierung der Forschung und Entwicklung hat sich in den letzten Jahren erheblich verstärkt. In diesem Beitrag analysieren wir die Determinanten der räumlichen Verteilung von ausländischen Technikaktivitäten in 96 deutschen Regionen. Zur Identifizierung ausländischer Technikaktivitäten wird das Konzept des grenzübergreifenden Eigentums auf Patentanträge angewandt. Die wichtigste Prämisse lautet, dass Regionen mit einer höheren verbundenen Vielfalt von Technikaktivitäten zwischen den einzelnen Sektoren mehr ausländische Technikaktivitäten anziehen. Aus den Schätzungen geht hervor, dass dies auf Regionen zutrifft, die sich durch ein hohes Maß an genereller technischer Stärke auszeichnen. Dies lässt darauf schließen, dass verbundene Vielfalt die technische Diversifizierung von ausländischen Unternehmen in Regionen an der Spitze der geografischen Hierarchie begünstigt.

The Forward-looking Disclosures of Corporate Managers: Theory and Evidence
Reint E. Gropp, Rasa Karapandza, Julian Opferkuch
IWH Discussion Papers,
Nr. 25,
2016
Abstract
We consider an infinitely repeated game in which a privately informed, long-lived manager raises funds from short-lived investors in order to finance a project. The manager can signal project quality to investors by making a (possibly costly) forward-looking disclosure about her project’s potential for success. We find that if the manager’s disclosures are costly, she will never release forward-looking statements that do not convey information to external investors. Furthermore, managers of firms that are transparent and face significant disclosure-related costs will refrain from forward-looking disclosures. In contrast, managers of opaque and profitable firms will follow a policy of accurate disclosures. To test our findings empirically, we devise an index that captures the quantity of forward-looking disclosures in public firms’ 10-K reports, and relate it to multiple firm characteristics. For opaque firms, our index is positively correlated with a firm’s profitability and financing needs. For transparent firms, there is only a weak relation between our index and firm fundamentals. Furthermore, the overall level of forward-looking disclosures declined significantly between 2001 and 2009, possibly as a result of the 2002 Sarbanes-Oxley Act.

Much Ado About Nothing: Sovereign Ratings and Government Bond Yields in the OECD
Makram El-Shagi
IWH Discussion Papers,
Nr. 22,
2016
Abstract
In this paper, we propose a new method to assess the impact of sovereign ratings on sovereign bond yields. We estimate the impulse response of the interest rate, following a change in the rating. Since ratings are ordinal and moreover extremely persistent, it proves difficult to estimate those impulse response functions using a VAR modeling ratings, yields and other macroeconomic indicators. However, given the highly stochastic nature of the precise timing of ratings, we can treat most rating adjustments as shocks. We thus no longer rely on a VAR for shock identification, making the estimation of the corresponding IRFs well suited for so called local projections – that is estimating impulse response functions through a series of separate direct forecasts over different horizons. Yet, the rare occurrence of ratings makes impulse response functions estimated through that procedure highly sensitive to individual observations, resulting in implausibly volatile impulse responses. We propose an augmentation to restrict jointly estimated local projections in a way that produces economically plausible impulse response functions.

Central Bank Transparency and Cross-border Banking
Stefan Eichler, Helge Littke, Lena Tonzer
Abstract
We analyze the effect of central bank transparency on cross-border bank activities. Based on a panel gravity model for cross-border bank claims for 21 home and 47 destination countries from 1998 to 2010, we find strong empirical evidence that a rise in central bank transparency in the destination country, on average, increases cross-border claims. Using interaction models, we find that the positive effect of central bank transparency on cross-border claims is only significant if the central bank is politically independent. Central bank transparency and credibility are thus considered complements by banks investing abroad.

Toward a Taylor Rule for Fiscal Policy
Martin Kliem, Alexander Kriwoluzky
Review of Economic Dynamics,
Nr. 2,
2014
Abstract
In DSGE models, fiscal policy is typically described by simple rules in which tax rates respond to the level of output. We show that there is only weak empirical evidence in favor of such specifications in US data. Instead, the cyclical movements of labor and capital income tax rates are better described by a contemporaneous response to hours worked and investment, respectively. We show that conditioning on these variables is also desirable from a normative perspective as it significantly improves welfare relative to output-based rules.

What Do We Learn from Schumpeterian Growth Theory?
Philippe Aghion, Ufuk Akcigit, Peter Howitt
P. Aghion, S. N. Durlauf (Hrsg.), Handbook of Economic Growth, Band 2B, Amsterdam: North Holland,
2014
Abstract
Schumpeterian growth theory has operationalized Schumpeter’s notion of creative destruction by developing models based on this concept. These models shed light on several aspects of the growth process that could not be properly addressed by alternative theories. In this survey, we focus on four important aspects, namely: (i) the role of competition and market structure; (ii) firm dynamics; (iii) the relationship between growth and development with the notion of appropriate growth institutions; and (iv) the emergence and impact of long-term technological waves. In each case, Schumpeterian growth theory delivers predictions that distinguish it from other growth models and which can be tested using micro data.

Islamic Finance in Europe

ECB Occasional Paper,
Nr. 146,
2013
Abstract
Islamic finance is based on ethical principles in line with Islamic religious law. Despite its low share of the global financial market, Islamic finance has been one of this sector's fastest growing components over the last decades and has gained further momentum in the wake of the financial crisis. The paper examines the development of and possible prospects for Islamic finance, with a special focus on Europe. It compares Islamic and conventional finance, particularly as concerns risks associated with the operations of respective institutions, as well as corporate governance. The paper also analyses empirical evidence comparing Islamic and conventional financial institutions with regard to their: (i) efficiency and profitability; and (ii) stability and resilience. Finally, the paper considers the conduct of monetary policy in an Islamic banking context. This is not uncomplicated given the fact that interest rates - normally a cornerstone of monetary policy - are prohibited under Islamic finance. Liquidity management issues are thus discussed here, with particular reference to the euro area.
