The Relationship between Knowledge Intensity and Market Concentration in European Industries: An inverted U-Shape
Niels Krap, Johannes Stephan
IWH Discussion Papers,
No. 3,
2008
Abstract
This paper is motivated by the European Union strategy to secure competitiveness for Europe in the globalising world by focussing on technological supremacy (the Lisbon - agenda). Parallel to that, the EU Commission is trying to take a more economic approach to competition policy in general and anti-trust policy in particular. Our analysis tries to establish the relationship between increasing knowledge intensity and the resulting market concentration: if the European Union economy is gradually shifting to a pattern of sectoral specialisation that features a bias on knowledge intensive sectors, then this may well have some influence on market concentration and competition policy would have to adjust not to counterfeit the Lisbon-agenda. Following a review of the available theoretical and empirical literature on the relationship between knowledge intensity and market structure, we use a larger Eurostat database to test the shape of this relationship. Assuming a causality that runs from knowledge to concentration, we show that the relationship between knowledge intensity and market structures is in fact different for knowledge intensive industries and we establish a non-linear, inverted U-curve shape.

On the Economics of Ex-Post Transfers in a Federal State: A Mechanism Design Approach
Martin Altemeyer-Bartscher, T. Kuhn
WWDP, 95,
No. 95,
2008
Abstract
As a common feature in many federal states grants-in aid are payed to jurisdictions ex post, i.e. after local policy measures have chosen. We show that the central government cannot offer grants ex ante in a federal states with informational asymmetries as well as inter-temporal commitment problems. Local governments’ incentives to provide public goods are distorted if they rely on federal grants-in-aid offered ex post. Furthermore it becomes obvious that local governments are apt to substitute tax revenue for higher grants-in-aid if relevant local data are unobservable for the central government. To which extend ex post transfers mitigate local governments’ incentives crucially depends on the information structure predominant in the federation.

Three methods of forecasting currency crises: Which made the run in signaling the South African currency crisis of June 2006?
Tobias Knedlik, Rolf Scheufele
IWH Discussion Papers,
No. 17,
2007
Abstract
In this paper we test the ability of three of the most popular methods to forecast the South African currency crisis of June 2006. In particular we are interested in the out-ofsample performance of these methods. Thus, we choose the latest crisis to conduct an out-of-sample experiment. In sum, the signals approach was not able to forecast the outof- sample crisis of correctly; the probit approach was able to predict the crisis but just with models, that were based on raw data. Employing a Markov-regime-switching approach also allows to predict the out-of-sample crisis. The answer to the question of which method made the run in forecasting the June 2006 currency crisis is: the Markovswitching approach, since it called most of the pre-crisis periods correctly. However, the “victory” is not straightforward. In-sample, the probit models perform remarkably well and it is also able to detect, at least to some extent, out-of-sample currency crises before their occurrence. It can, therefore, not be recommended to focus on one approach only when evaluating the risk for currency crises.

Determinants of Female Migration – The Case of German NUTS 3 Regions
Alexander Kubis, Lutz Schneider
IWH Discussion Papers,
No. 12,
2007
Abstract
Our study examines the regional patterns and determinants of migration flows of young women. At the NUTS-3 regional level, i.e. the district level (Kreise), the German internal migration flows of the year 2005 are explored. From descriptive statistics it can be seen that peripheral regions in East Germany face the strongest migration deficit with respect to young women, whereas agglomerations in West Germany but also in the East benefit from an intense migration surplus within this group. An econometric analysis of determinants of regional migration flows gives evidence of the importance of labour market, family-related and educational migration motives. Generally speaking, young women tend to choose regions with good income and job opportunities, in addition they seem to be attracted by regions enabling an appropriate balance between family and career. Furthermore the existence of excellent educational facilities is a significant influence for young women’s migration. This educationally motivated type of migration generates a long lasting effect on the regional migration balance, especially when the educational opportunities in the destination region are associated with adequate career perspectives for high qualified female graduates. In view of considerable losses due to migration, the study shows various options for action. An important course of action is to incorporate policy measures improving regional employment and income opportunities. Secondly, extending vocational and academic offers addressed to women seems to be a suitable way to stimulate women’s immigration. Moreover, enhancing the social infrastructure, which contributes to a satisfactory work life balance, might attract young women or at least reduce the number of them leaving a region.

Structural Policy in East Germany – A Discussion about the Common Task “Improvement of Regional Economic Structure“
Mirko Titze
Wirtschaft im Wandel,
No. 10,
2007
Abstract
Trotz intensiver Wirtschaftsförderung ist es bis heute nicht gelungen, in den Neuen Bundesländern eine Art in sich selbst tragenden Aufschwung zu initiieren. Seit dem Jahr 1995 ist der Konvergenzprozeß Ostdeutschlands ins Stocken geraten. Auch wenn die ostdeutsche Konjunktur aktuell an Fahrt gewinnt, so ist die Sinnhaftigkeit der Wirtschaftsförderung in Ostdeutschland immer wieder Gegenstand der wirtschaftspolitischen Debatte. Der vorliegende Beitrag beschäftigt sich mit einem der wichtigsten Förderinstrumente im Rahmen des Aufbau Ost – der „Gemeinschaftsaufgabe zur Verbesserung der regionalen Wirtschaftsstruktur“. Die Wirksamkeit dieses Instruments im Sinne des Wachstumsziels wurde in empirischen Studien nachgewiesen. Nichtsdestotrotz ist das über dieses Instrument zur Verfügung stehende Fördermittelvolumen in den letzten zehn Jahren sehr stark gesunken. Eine weitere Reduzierung der Mittel ist sehr wahrscheinlich. Bei immer noch vorhandenen strukturellen Defiziten müssen die Neuen Bundesländer auf diesen Umstand mit der stringenten Ausgestaltung ihrer Regionalen Förderprogramme reagieren. Der vorliegende Beitrag zeigt, daß insbesondere in dem Regionalen Förderprogramm des Landes Brandenburg und ansatzweise auch in dem Sachsens ein individuelles Profil erkennbar wird. Ob diese Vorgehensweise die richtige ist, läßt sich ex ante jedoch nicht bestimmen.

Spillover Effects of Spatial Growth Poles - a Reconciliation of Conflicting Policy Targets?
Alexander Kubis, Mirko Titze, Joachim Ragnitz
IWH Discussion Papers,
No. 8,
2007
Abstract
Regional economic policy faces the challenge of two competing policy goals - reducing regional economic disparities vs. promoting economic growth. The allocation of public funds has to weigh these goals particularly under the restriction of scarce financial re- sources. If, however, some region turns out to be a regional growth pole with positive spillovers to its disadvantaged periphery, regional policies could be designed to recon- cile the conflicting targets. In this case, peripheral regions could indirectly participate in the economic development of their growing cores. We start our investigation by defining and identifying such growth poles among German regions on the NUTS 3 administrative level based on spatial and sectoral effects. Using cluster analysis, we determine significant characteristics for the general identification of growth poles. Patterns in the sectoral change are identified by means of the change in the employment. Finally, we analyze whether and to what extent these growth poles ex- ert spatial spillover effects on neighbouring regions and thus mitigate contradictory in- terests in regional public policy. For this purpose, we apply a Spatial-Cross-Regressive- Model (SCR-Model) including the change in the secondary sector which allows to con- sider functional economic relations on the administrative level chosen (NUTS 3).

The Impact of Competition on Bank Orientation
Hans Degryse, Steven Ongena
Journal of Financial Intermediation,
No. 3,
2007
Abstract
How do banks react to increased competition? Recent banking theory significantly disagrees regarding the impact of competition on bank orientation—i.e., the choice of relationship-based versus transactional banking. We empirically investigate the impact of interbank competition on bank branch orientation. We employ a unique data set containing detailed information on bank–firm relationships. We find that bank branches facing stiff local competition engage considerably more in relationship-based lending. Our results illustrate that competition and relationships are not necessarily inimical.

The Economic Geography of Offshoring.
Ulrich Blum
Offshoring Journal,
No. 1,
2007
Abstract
Der Begriff Offshoring bezeichnet die (zumindest teilweise) Geschäftsverlagung nach Übersee bzw. den Einkauf ehemals unternehmenseigener Dienstleistungen aus Entwicklungsländern. Heute sind Offshoring-Aktivitäten vor allem bei Dienstleitungen interessant, welche digitale Verarbeitungsprozesse beinhalten. Auch Unternehmensleistungen mit niedrigen Transaktionskosten bzw. Aktivitäten wo andere Länder Standortvorteile aufweisen eignen sich für Offshoring. Allerdings sind die Möglichkeiten des Offshoring auch immer individuell vom Unternehmen selbst sowie vom entsprechenden Rechtssystem des Landes abhängig.

The East German Cement Cartel: Cartel Efficiency and Policy after Economic Transformation
Ulrich Blum
Eastern Economic Review,
2007
Abstract
Im Jahr 2003 wurde von der deutschen Kartellbehörde ein Zementkartell aufgedeckt. Eines der Hauptzentren des Kartells war Ostdeutschland, wo das ostdeutsche Zementkombinat Anfang der 1990er Jahre von der Treuhand im Rahmen der Privatisierung der ehemals volkseigenen Betriebe an vier große Zementproduzenten verkauft wurden.
In diesem Aufsatz stellen wir die Behauptung der Kartellbehörde in Frage, dass durch das Kartell Überschussgewinne auf dem ostdeutschen Markt erziehlt wurden. Wir behaupten, dass die juristischen Anzeichen eines Kartells nicht zwangsläufig den wirtschaftlichen Hinweisen entsprechen. Zu diesem Zweck versuchen wir nachzuweisen, dass die Zementnachfrage regional begrenzt ist und nur in einem sehr kleinen Umfang von der Produktpalette abhängt. Wenn das Zementkartell einen Einfluss auf die Wirtschaft hatte, dann müsste sich seine Zerschlagung in der Veränderung der individuellen Nachfragefunktion der Unternehmen widerspiegeln. Allerdings konnten mit dem verwendeten ökonometrischen Modell keine strukturellen Nachfrageänderungen beobachtet werden. Dies kann unter anderem damit begründet werden, dass Billigimporte aus Polen und der Tschechei sowie mittelständische Unternehmen dafür gesorgt haben, dass das Zementkartell seine Wirkung nie voll entfalten konnte.
Der Aufsatz zeigt, dass selbst in etablierten Marktwirtschaften wie Westdeutschland die Schwierigkeit besteht, Wettbewerb in bestimmten Industriebereichen zu generieren und dass hierfür die Offenheit der Wirtschaft entscheidend ist.
