Abstract
This paper analyzes the role of common data problems when identifying structural breaks in small samples. Most notably, we survey small sample properties of the most commonly applied endogenous break tests developed by Brown et al. (J R Stat Soc B 37:149–163, 1975) and Zeileis (Stat Pap 45(1):123–131, 2004), Nyblom (J Am Stat Assoc 84(405):223–230, 1989) and Hansen (J Policy Model 14(4):517–533, 1992), and Andrews et al. (J Econ 70(1):9–38, 1996). Power and size properties are derived using Monte Carlo simulations. We find that the Nyblom test is on par with the commonly used F type tests in a small sample in terms of power. While the Nyblom test’s power decreases if the structural break occurs close to the margin of the sample, it proves far more robust to nonnormal distributions of the error term that are found to matter strongly in small samples although being irrelevant asymptotically for all tests that are analyzed in this paper.

Extreme Risks in Financial Markets and Monetary Policies of the Euro-candidates
Hubert Gabrisch, Lucjan T. Orlowski
Comparative Economic Studies,
Nr. 4,
2011
Abstract
This study investigates extreme tail risks in financial markets of the euro-candidate countries and their implications for monetary policies. Our empirical tests show the prevalence of extreme risks in the conditional volatility series of selected financial variables, that is, interbank rates, equity market indexes and exchange rates. We argue that excessive instability of key target and instrument variables should be mitigated by monetary policies. Central banks in these countries will be well-advised to use both standard and unorthodox (discretionary) tools of monetary policy while steering their economies out of the financial crisis and through the euro-convergence process.

Disentangling Barriers to Internationalization
C. Arndt, Claudia M. Buch, A. Mattes
Canadian Journal of Economics,
Nr. 1,
2012
Abstract
Recent literature on multinational firms has focused on low productivity as a barrier to the internationalization of firms. But labour market frictions or financial constraints may also hamper internationalization. In order to assess the importance of these barriers, we present new empirical evidence on the extensive and intensive margin of exports and foreign direct investment (FDI) based on micro-level data of German firms. First, we find a positive impact of firm size and productivity on firms’ international activities. Second, labour market frictions can constitute barriers to foreign activities. Third, self-reported financial constraints have no impact on firms’ internationalization decisions.

Personal Bankruptcy and Credit Supply and Demand
Reint E. Gropp, J. K. Scholz, M. J. White
Quarterly Journal of Economics,
Nr. 1,
1997
Abstract
This paper examines how personal bankruptcy and bankruptcy exemptions affect the supply and demand for credit. While generous state-level bankruptcy exemptions are probably viewed by most policy-makers as benefiting less-well-off borrowers, our results using data from the 1983 Survey of Consumer Finances suggest that they increase the amount of credit held by high-asset households and reduce the availability and amount of credit to low-asset households, conditioning on observable characteristics. Thus, bankruptcy exemptions redistribute credit toward borrowers with high assets. Interest rates on automobile loans for low-asset households also appear to be higher in high exemption states.

The Tradeoff Between Redistribution and Effort: Evidence from the Field and from the Lab
Claudia M. Buch, C. Engel
Max Planck Institute for Research on Collective Goods Working Paper,
Nr. 10,
2012
Abstract
We use survey and experimental data to explore how effort choices and preferences for redistribution are linked. Under standard preferences, redistribution would reduce effort. This is different with social preferences. Using data from the World Value Survey, we find that respondents with stronger preferences for redistribution tend to have weaker incentives to engage in effort, but that the reverse does not hold true. Using a lab experiment, we show that redistribution choices even increase in imposed effort. Those with higher ability are willing to help the needy if earning income becomes more difficult for everybody.

Hochschulen als regionaler Innovationsmotor? Innovationstransfer aus Hochschulen und seine Bedeutung für die regionale Entwicklung
Michael Fritsch, Viktor Slavtchev, N. Steigenberger
Arbeitspapier / Hans-Böckler-Stiftung, Nr. 158,
2008
Abstract
Innovation ist der wesentliche Motor wirtschaftlicher Entwicklung. Denn vor allem die Andersverwendung von Ressourcen, weniger deren Mehreinsatz führt zu Wachstum und Wohlstand. Aus diesem Grund stellt Innovation auch einen wichtigen Ansatzpunkt für eine auf Wachstum zielende Politik dar. Dies gilt sowohl auf gesamtwirtschaftlicher Ebene als auch für einzelne Branchen und Regionen.
In Innovationsprozessen stellt Wissen die entscheidende Ressource dar. Wissen ist mehr als bloße Information. Es umfasst insbesondere auch die Fähigkeit, Informationen zu interpretieren und anzuwenden bzw. ihre Anwendbarkeit einzuschätzen. Wissen ist an Menschen gebunden und lässt sich vielfach nur in direktem persönlichen Kontakt weitergeben. Aus diesem Grund hat Wissen eine regionale Dimension: Die Verfügbarkeit von Wissen hängt davon ab, wo sich die Menschen aufhalten, die über dieses Wissen verfügen. Dies ist ein wesentlicher Grund dafür, dass die Fähigkeit zur Innovation von Region zu Region wesentliche Unterschiede aufweisen kann.
Für eine Politik, die auf die Stärkung der Innovationsfähigkeit von Regionen gerichtet ist, kommt den öffentlichen Forschungseinrichtungen – Universitäten, Fachhochschulen und außeruniversitären Forschungsinstituten – aus mindestens zwei Gründen zentrale Bedeutung zu:
Erstens verfügen die öffentlichen Forschungseinrichtungen in besonderem Maße über innovationsrelevantes Wissen. Ihre Kernaufgabe ist es, Wissen zu produzieren, zu sammeln und weiterzugeben.
Zweitens ist der Bereich der öffentlichen Forschungseinrichtungen – im Gegensatz zur privaten Wirtschaft – von der Politik direkt gestaltbar.
Aus diesen Gründen stellt die Steuerung des Hochschulsektors ein zentrales Handlungsfeld der Innovationspolitik dar.

Natural-resource or Market-seeking FDI in Russia? An Empirical Study of Locational Factors Affecting the Regional Distribution of FDI Entries
K. Gonchar, Philipp Marek
HSE Working Papers, Series: Economics, WP BRP 26/EC/2013,
2013
Abstract
This paper analyzes the spatial distribution of foreign direct investment (FDI) across regions in Russia. Our analysis employs data on Russian firms with a foreign investor during the 2000-2009 period and links regional statistics in the conditional logit model. The main findings are threefold. First, we conclude that market-related factors and the availability of natural resources are important factors in attracting FDI. Second, existing agglomeration economies encourage foreign investors. Third, the findings imply that service-oriented FDI co-locates with extraction industries in resource-endowed regions.

Abstract
Leistungsbilanzungleichgewichte innerhalb der EU sind symptomatisch für die europäische Schuldenkrise. Zwischen ihnen und den nationalen Budgetdefiziten besteht ein enger Zusammenhang. Dazu, wie eine problematische Entwicklung der beiden Größen identifiziert und ein Gleichgewicht wiederhergestellt werden kann, gibt es eine Vielzahl von Vorschlägen. Die Autoren bewerten diese mit Hilfe einer Kosten-Nutzen-Analyse.

Do Manufacturing Firms Benefit from Services FDI? – Evidence from Six New EU Member States
J. Damijan, Crt Kostevc, Philipp Marek, Matija Rojec
IWH Discussion Papers,
Nr. 5,
2015
Abstract
This paper focuses on the effect of foreign presence in the services sector on the productivity growth of downstream customers in the manufacturing sector in six EU new member countries in the course of their accession to the European Union. For this purpose, the analysis combines firm-level information, data on economic structures and annual national input-output tables. The findings suggest that services FDI may enhance productivity of manufacturing firms in Central and Eastern European (CEE) countries through vertical forward spillovers, and thereby contribute to their competitiveness. The consideration of firm characteristics shows that the magnitude of spillover effects depends on size, ownership structure, and initial productivity level of downstream firms as well as on the diverging technological intensity across sector on the supply and demand side. The results suggest that services FDI foster productivity of domestic rather than foreign controlled firms in the host economy. For the period between 2003 and 2008, the findings suggest that the increasing share of services provided by foreign affiliates enhanced the productivity growth of domestic firms in manufacturing by 0.16%. Furthermore, the firms’ absorptive capability and the size reduce the spillover effect of services FDI on the productivity of manufacturing firms. A sectoral distinction shows that firms at the end of the value chain experience a larger productivity growth through services FDI, whereas the aggregate positive effect seems to be driven by FDI in energy supply. This does not hold for science-based industries, which are spurred by foreign presence in knowledge-intensive business services.

The Role of Rating Agencies in Financial Crises: Event Studies from the Asian Flu
Makram El-Shagi
Cambridge Journal of Economics,
2010
Abstract
Based on case studies from countries that have been hit hardest by the Asian financial crisis of 1997, the present paper shows that the accusation that sovereign ratings led to a severe acceleration of the crisis is unconvincing and that the empirical method often used to support accusations against rating agencies is inappropriate for the problem under analysis. Rather, it must be emphasised that ratings were downgraded in most countries very shortly before the end of the crisis. In some countries, the ratings were even further downgraded after the end of the crisis as countries started to recover. This is not in line with the thesis that the crisis was accelerated by rating agencies.
