Journal of Development Economics,
No. 1,

Abstract
This paper investigates the driving forces of output change in 77 countries during the period 1970–2000. A flexible modeling strategy is adopted that accounts for (i) the inefficient use of resources, and (ii) different production technologies across countries. The proposed model can identify technical, efficiency, and input change for each of three endogenously determined regimes. Membership in these regimes is estimated, rather than determined ex ante. This framework enables explorations into the determinants of output growth and convergence issues in each regime.

Deriving the Term Structure of Banking Crisis Risk with a Compound Option Approach: The Case of Kazakhstan
Stefan Eichler, Alexander Karmann, Dominik Maltritz
Discussion paper, Series 2: Banking and financial studies, No. 01/2010,
No. 1,
2010
Abstract
We use a compound option-based structural credit risk model to infer a term structure of banking crisis risk from market data on bank stocks in daily frequency. Considering debt service payments with different maturities this term structure assigns a separate estimator for short- and long-term default risk to each maturity. Applying the Duan (1994) maximum likelihood approach, we find for Kazakhstan that the overall crisis probability was mainly driven by short-term risk, which increased from 25% in March 2007 to 80% in December 2008. Concurrently, the long-term default risk increased from 20% to only 25% during the same period.

Industry Concentration and Regional Innovative Performance – Empirical Evidence for Eastern Germany
Christoph Hornych, Michael Schwartz
Post-Communist Economies,
2009
Abstract
Regarding technological innovativeness, the transformed economy of the former German Democratic Republic (GDR) clearly lags behind the western part of the country. To face this weakness a broad mixture of policy measures was carried out in recent years. Particular attention is drawn to the development of industry concentrations and economic ‘clusters’. However, little is known about the effectiveness of these policy measures regarding how industry concentrations in fact promote innovative performance in Eastern Germany. The present study tries to fill this gap by analysing the relationship between industry concentration in Eastern Germany and regional innovative performance. Our empirical analysis is based upon the number of patent applications of 22 manufacturing industries in 22 Eastern German planning regions. The estimated regression models indicate an inverted-U relationship between the degree of industry concentration and innovative performance. An exceedingly high degree of industry concentration in one region hampers regional innovative output. We discuss policy implications of our findings and give recommendations for future refinement of ‘cluster’-supporting policy schemes in Eastern Germany.

Shocks at Large Banks and Banking Sector Distress: The Banking Granular Residual
S. Blank, Claudia M. Buch, Katja Neugebauer
Journal of Financial Stability,
No. 4,
2009
Abstract
Size matters in banking. In this paper, we explore whether shocks originating at large banks affect the probability of distress of smaller banks and thus the stability of the banking system. Our analysis proceeds in two steps. In a first step, we follow Gabaix and construct a measure of idiosyncratic shocks at large banks, the so-called Banking Granular Residual. This measure documents the importance of size effects for the German banking system. In a second step, we incorporate this measure of idiosyncratic shocks at large banks into an integrated stress-testing model for the German banking system following De Graeve et al. (2008). We find that positive shocks at large banks reduce the probability of distress of small banks.

Margins of international banking: Is there a productivity pecking order in banking, too?
Claudia M. Buch
Bundesbank Discussion Paper 12/2009,
2009
Abstract
Modern trade theory emphasizes firm-level productivity differentials to explain
the cross-border activities of non-financial firms. This study tests whether a
productivity pecking order also determines international banking activities. Using
a novel dataset that contains all German banks’ international activities, we
estimate the ordered probability of a presence abroad (extensive margin) and the
volume of international assets (intensive margin). Methodologically, we enrich the
conventional Heckman selection model to account for the self-selection of banks
into different modes of foreign activities using an ordered probit. Four main
findings emerge. First, similar to results for non-financial firms, a productivity
pecking order drives bank internationalization. Second, only a few non-financial
firms engage in international trade, but many banks hold international assets, and
only a few large banks engage in foreign direct investment. Third, in addition to
productivity, risk factors matter for international banking. Fourth, gravity-type
variables have an important impact on international banking activities.

What Happened to the East German Housing Market? – A Historical Perspective on the Role of Public Funding –
Claus Michelsen, Dominik Weiß
IWH Discussion Papers,
No. 20,
2009
Abstract
The paper analyses the development of the East German housing market after the reunification of the former German Democratic Republic and the Federal Republic of Germany in 1990. We analyse the dynamics of the East German housing market within the framework of the well-known stock-flow model, proposed by DiPasquale and Wheaton. We show that the today observable disequilibrium to a large extend is caused by post-unification housing policy and its strong fiscal incentives to invest into the housing stock. Moreover, in line with the stylized empirical facts, we show that ‘hidden reserves’ of the housing market were reactivated since the economy of East Germany became market organized. Since initial undersupply was overcome faster than politicians expected, the implemented fiscal stimuli were too strong. In contrast to the widespread opinion that outward migration caused the observable vacancies, this paper shows that not weakness of demand but supply side policies caused the observable disequilibrium.

Germany’s Production of Export Goods: Human Capital Content Slightly Exceeds that of Imports
Hans-Ulrich Brautzsch, Udo Ludwig
Wirtschaft im Wandel,
No. 11,
2009
Abstract
Getrieben von der wachsenden Weltnachfrage sowie der Internationalisierung der nationalen Produktionsprozesse und begünstigt durch die Verbesserung der preislichen Wettbewerbsfähigkeit hat die deutsche Wirtschaft im Jahrzehnt vor der derzeitigen Weltfinanzkrise die Exportaktivitäten drastisch ausgeweitet. Im gleichen Zeitraum hat sich im Zuge der Tertiärisierung der Wirtschaft die Ausstattung der Produzenten mit Humankapital erhöht. Vor diesem Hintergrund geht die Studie dem qualitativen Wandel des Faktors Arbeit, gemessen an der formalen Qualifikation der Beschäftigten, bei der Entstehung der Exportgüter nach und vergleicht ihn mit dem Geschehen auf der Importseite. Die mit dem Input-Output-Modell und einer eigens dafür generierten Datenbasis erstmalig für das vereinigte Deutschland erzielten empirischen Ergebnisse weisen zwar auf einen in den deutschen Exporten verkörperten Vorteil hin, der jedoch gegenüber den Importen qualifikatorisch nur relativ gering ist. Unter Einschluss des seit Mitte der 90er Jahre anhaltenden Exportüberschusses ist dieser Vorteil jedoch, absolut betrachtet, recht groß. Das spricht für die Realisierung eines Humankapitalvorteils Deutschlands im Exportgeschäft.

Monopolistic Competition and Costs in the Health Care Sector
Ingmar Kumpmann
IWH Discussion Papers,
No. 17,
2009
Abstract
Competition among health insurers is widely considered to be a means of enhancing efficiency and containing costs in the health care system. In this paper, it is argued that this could be unsuccessful since health care providers hold a strong position on the market for health care services. Physicians exert a type of monopolistic power which can be described by Chamberlin’s model of monopolistic competition. If many health insurers compete with one another, they cannot counterbalance the strong bargaining position of the physicians. Thus, health care expenditure is higher, financing either extra profits for physicians or a higher number of them. In addition, health insurers do not have an incentive to contract selectively with health care providers as long as there are no price differences between physicians. A monopolistic health insurer is able to counterbalance the strong position of physicians and to achieve lower costs.

The Gender Pay Gap under Duopsony: Joan Robinson meets Harold Hotelling
Boris Hirsch
Scottish Journal of Political Economy,
No. 5,
2009
Abstract
This paper presents an alternative explanation of the gender pay gap resting on a simple Hotelling-style duopsony model of the labour market. Since there are only two employers, equally productive women and men have to commute and face travel cost to do so. We assume that some women have higher travel cost, e.g., due to more domestic responsibilities. Employers exploit that women on average are less inclined to commute and offer lower wages to all women. Since women's firm-level labour supply is for this reason less wage-elastic, this model is in line with Robinson's explanation of wage discrimination.

Out-migration and Regional Convergence

Wirtschaft im Wandel,
20 Jahre Deutsche Einheit - Teil 1 -
2009
Abstract
Seit 1989 haben netto über 1,8 Millionen Menschen Ostdeutschland den Rücken gekehrt. In diesem Kontext stellt sich die Frage, welcher Zusammenhang zwischen der Binnenmigration – ökonomisch betrachtet der Humankapitalmobilität – und dem regionalen Wachstum besteht. Aus theoretischer Sicht sprechen Gründe sowohl für als auch gegen eine konvergenzfördernde Wirkung von Migration. Insbesondere bei starker Positivselektion der Migranten sollten die Wanderungsbewegungen eher gegen eine Angleichung der Wirtschaftskraft von Regionen wirken.
Im vorliegenden Beitrag wird die Frage, wie Migration und Konvergenz, verstanden als Angleichung der Arbeitsproduktivität, zusammenhängen, auf regionaler Ebene für Deutschland im Zeitraum von 1995 bis 2006 empirisch analysiert. Der methodische Ansatz folgt dem Konzept der Beta-
Konvergenz, geschätzt wird ein Querschnittsmodell auf Basis von Kreisdaten, die auf dieser Ebene vorliegende räumliche Korrelation wird im Modell berücksichtigt.
Im Ergebnis zeigt sich zunächst ein signifikanter Konvergenzprozess auf regionaler Ebene; die ostdeutschen Regionen holen dabei besonders schnell auf. Hinsichtlich der Wirkung von Migration auf regionale Konvergenz finden sich gegenläufige Tendenzen. Die Abwanderung aus armen Regionen wird zwar einerseits begleitet von einem hohen Produktivitätswachstum, die komplementäre Zuwanderung in reiche Regionen geht dort andererseits ebenso mit höherem Wachstum einher. Insofern ist der Konvergenzeffekt der Migration unbestimmt, allerdings sprechen die Ergebnisse für einen wanderungsbedingten Effizienzgewinn auf volkswirtschaftlicher Ebene, wenn die Migration von schwächeren in stärkere Regionen fließt.
