A Systemic View on Knowledge-based Development Metrics

Mirko Titze, Michael Schwartz, Matthias Brachert
International Journal of Knowledge-Based Development, No. 1, 2012
Abstract
Drawing on the systems perspective of innovation processes, this article proposes a conceptual approach for a comprehensive analysis of regional knowledge generation and transfer. Instead of focusing on one single indicator, the approach emphasizes the importance to take multiple channels of knowledge transfer into account. This provides valuable insights into the spatial structure of innovation processes on different levels. We disentangle the innovation process and consider four different layers: i.) publications in peer-reviewed journals, ii.) patent applications, iii.) formal R&D collaboration projects, the iv.) localized input-output relations. Further, we demonstrate the relevance of the „multi-layer approach‟ by applying it empirically to a specific regional innovation system: The Free State of Saxony – a federal state in Germany. We argue that the approach could be a valuable tool to inform policy-makers about knowledge-based regional development strategies.

Rules versus Discretion in Loan Rate Setting

Geraldo Cerqueiro, Hans Degryse, Steven Ongena
Journal of Financial Intermediation, No. 4, 2011
Abstract
Loan rates for seemingly identical borrowers often exhibit substantial dispersion. This paper investigates the determinants of the dispersion in interest rates on loans granted by banks to small and medium sized enterprises. We associate this dispersion with the loan officers’ use of “discretion” in the loan rate setting process. We find that “discretion” is most important if: (i) loans are small and unsecured; (ii) firms are small and opaque; (iii) the firm operates in a large and highly concentrated banking market; and (iv) the firm is distantly located from the lender. Consistent with the proliferation of information-technologies in the banking industry, we find a decreasing role for “discretion” over time in the provision of small credits to opaque firms. While widely used in the pricing of loans, “discretion” plays only a minor role in the decisions to grant loans.

Selektivität, soziale Bindung und räumliche Mobilität - Eine Analyse der Rückkehrpräferenz nach Ostdeutschland

Lutz Schneider, Alexander Kubis, D. Wiest
Zeitschrift für Wirtschaftsgeographie, No. -1, 2011
Abstract
Selectivity, social ties and spatial mobility. An analysis of preferences for return migration to East Germany. In the public debate, brain drain from East Germany is supposed to be the most critical trend regarding the development and catching up of the New Länder. Therefore, potential for in- and re-migration has attracted much attention at least in the political context. Our contribution analyses the remigration potential on basis of data from a DFG research project focussing on the re-migration intentions of people formerly emigrated from Saxony-Anhalt. The analysis concentrates on the following aspects: the effect of job market success after emigration; the impact of social ties to the origin and the host region and on the selectivity of re-migration preferences. The econometric results confirm several expected effects: On the one hand an individual’s job market success reduces the intention to return. Likewise, the re-migration preference increases for people whose expectations were disappointed. On the other hand, the relevance of social ties to the origin region for re-migration dispositions is confirmed by the estimations. Yet, regarding selectivity of re-migration preferences in terms of human capital econometric results are somewhat ambiguous.

Modelling Country Default Risk as a Latent Variable: A Multiple Indicators Multiple Causes Approach

A. Bühn, Stefan Eichler, Dominik Maltritz
Applied Economics, No. 36, 2012
Abstract
We study the determinants of country default risk by applying a Multiple Indicators Multiple Causes (MIMIC) model. This accounts for the fact that country default risk is an unobservable variable. Whereas existing (regression-based) approaches typically use only one of several possible country default risk indicators as the dependent variable, the MIMIC model enables us to consider several indicators at once. The simultaneous consideration of sovereign yield spreads and Standard and Poor (S&P) ratings may help to improve the identification of the latent country default risk. Our results confirm most of the literature's main findings regarding important determinants of country default risk, refute others and provide new evidence to controversial questions.

Der Euro als Triebfeder des deutschen Exports?

Götz Zeddies
List Forum für Wirtschafts- und Finanzpolitik, No. 3, 2011
Abstract
Die ausufernde Verschuldung insbesondere der südeuropäischen Mitgliedstaaten stellt die Europäische Währungsunion (EWU) derzeit vor große Herausforderungen. Während über lange Zeit Einigkeit darüber herrschte, den vollständigen Erhalt der Währungsunion mit einem milliardenschweren Rettungsschirm zu sichern, wurden jüngst erste Forderungen nach einem Austritt Griechenlands aus dem Euroraum laut. Insbesondere in Deutschland wird befürchtet, dass ein Austritt einzelner Länder oder gar ein kompletter Zerfall der Währungsunion mit großen ökonomischen Nachteilen verbunden wäre. So wird argumentiert, dass gerade Deutschland aufgrund seiner hohen Exportorientierung und jahrelanger Lohnzurückhaltung mehr als alle anderen EWU-Mitgliedsländer vom Euro profitiere. Vor diesem Hintergrund untersucht der vorliegende Beitrag, welche Konsequenzen ein Austritt einzelner Länder aus der Währungsunion und damit verbundene Veränderungen der preislichen Wettbewerbsfähigkeit auf die deutschen Ausfuhren in diese Länder hätte. Im Ergebnis zeigt sich, dass sich ein Austritt Irlands, Griechenlands, Spaniens und Portugals kaum negativ auf die deutschen Exporte auswirken würde. Ein kompletter Zerfall der Währungsunion und eine Wiedereinführung nationaler Währungen dürfte dagegen, aufgrund der nach wie vor recht hohen Bedeutung des Euroraums als Absatzmarkt für deutsche Produkte, den Exportzuwachs spürbar dämpfen.

Trade Misinvoicing: The Dark Side of World Trade

A. Buehn, Stefan Eichler
World Economy, No. 8, 2011
Abstract
We analyse the determinants of trade misinvoicing using data on 86 countries from 1980 to 2005. In a simple microeconomic framework, we derive the determinants of four different types of trade misinvoicing taking into account that only the financial incentives determine whether and how much exports/imports to underinvoice or overinvoice, whereas the deterrents only affect the extent of misinvoicing. The hypothesised determinants are tested using data on discrepancies in bilateral trade with the United States. We find that the black market premia and tariffs motivate illegal trading activities. Higher financial penalties effectively act as a deterrent to this crime.

Did the Crisis Affect Potential Output?

Makram El-Shagi
Applied Economics Letters, No. 8, 2011
Abstract
Conventional Phillips-curve models that are used to estimate the output gap detect a substantial decline in potential output due to the present crisis. Using a multivariate state space model, we show that this result does not hold if the long run role of excess liquidity (that we estimate endogeneously) for inflation is taken into account.

Bank-specific Shocks and the Real Economy

Claudia M. Buch, Katja Neugebauer
Journal of Banking and Finance, No. 8, 2011
Abstract
Governments often justify interventions into the financial system in the form of bail outs or liquidity assistance with the systemic importance of large banks for the real economy. In this paper, we analyze whether idiosyncratic shocks to loan growth at large banks have effects on real GDP growth. We employ a measure of idiosyncratic shocks which follows Gabaix (forthcoming). He shows that idiosyncratic shocks to large firms have an impact on US GDP growth. In an application to the banking sector, we find evidence that changes in lending by large banks have a significant short-run impact on GDP growth. Episodes of negative loan growth rates and the Eastern European countries in our sample drive these results.

University Cities: Including Universities and Research Institutes into Strategies for Urban Growth

Peter Franz
International Journal of Knowledge-Based Development, 2011
Abstract
The topic of this special issue refers to the observation that many larger and middle-sized cities dispose of a considerable potential of institutions creating and disseminating knowledge. This kind of endowment seems to be especially valuable in an upcoming knowledge-based economy. Recent strategic concepts and inter-city competitions referring to ‘knowledge-based urban development’, ‘knowledge city’, ‘creative city’, ‘science city’ or ‘entrepreneurial university’ indicate that urban planners and politicians are beginning to search for strategies to take advantage and to make use of this potential. The papers in this special issue a) present case studies of cities trying to activate their knowledge resources for local economic growth, b) deal with regulatory barriers and problems for cities applying ‘knowledge city’ strategies, c) analyze the university support for entrepreneurial activities, and d) discuss some implications of ‘knowledge city’ strategies for architecture and urban planning.

ICT Adoption and Heterogeneity in Production Technologies: Evidence for Chilean Retailers

Gaaitzen J. de Vries, Michael Koetter
Oxford Bulletin of Economics and Statistics, No. 4, 2011
Abstract
The adoption of information and communication technology (ICT) can have far-reaching effects on the nature of production technologies. Because ICT adoption is incomplete, especially in developing countries, different groups of firms will have different production technologies. We estimate a latent class stochastic frontier model, which allows us to test for the existence of multiple production technologies across firms and consider the associated implications for efficiency measures. We use a unique data set of Chilean retailers, which includes detailed information on ICT adoption. We find three distinct production technologies. The probability of membership in a more productive group is positively related to ICT use.
