Industry Specialization, Diversity and the Efficiency of Regional Innovation Systems

Determinants of Innovative Behaviour,
2008
Abstract
Innovation processes are characterized by a pronounced division of labor between actors. Two types of externality may arise from such interactions. On the one hand, a close location of actors affiliated to the same industry may stimulate innovation (MAR externalities). On the other hand, new ideas may be born by the exchange of heterogeneous and complementary knowledge between actors, which belong to different industries (Jacobs’ externalities). We test the impact of both MAR as well as Jacobs’ externalities on innovative performance at the regional level. The results suggest an inverted u-shaped relationship between regional specialization in certain industries and innovative performance. Further key determinants of the regional innovative performance are private sector R&D and university-industry collaboration.

An Assessment of Bank Merger Success in Germany
Michael Koetter
German Economic Review,
No. 2,
2008
Abstract
German banks have experienced a merger wave since the early 1990s. However, the success of bank mergers remains a continuous matter of debate.This paper suggests a taxonomy to evaluate post-merger performance on the basis of cost and profit efficiency (CE and PE). I identify successful mergers as those that fulfill simultaneously two criteria. First, merged institutes must exhibit efficiency levels above the average of non-merging banks. Second, banks must exhibit efficiency changes between merger and evaluation year above efficiency changes of non-merging banks. I assess the post-merger performance up to 11 years after the mergers and relate it to the transfer of skills, the adequacy to merge distressed banks and the role of geographical distance. Roughly every second merger is a success in terms of either CE or PE. The margin of success in terms of CE is narrow, as efficiency differentials between merging and non-merging banks are around 1 and 2 percentage points. PE performance is slightly larger. More importantly, mergers boost in particular the change in PE, thus indicating persistent improvements of merging banks to improve the ability to generate profits.

Deeper, Wider and More Competitive? Monetary Integration, Eastern Enlargement and Competitiveness in the European Union
Gianmarco Ottaviano, Daria Taglioni, Filippo di Mauro
ECB Working Paper,
No. 847,
2008
Abstract
What determines a country’s ability to compete in international markets? What fosters the global competitiveness of its firms? And in the European context, have key elements of the EU strategy such as EMU and enlargement helped or hindered domestic firms’ competitiveness in local and global markets? We address these questions by calibrating and simulating a conceptual framework that, based on Melitz and Ottaviano (2005), predicts that tougher and more transparent international competition forces less productive firms out the market, thereby increasing average productivity as well as reducing average prices and mark-ups. The model also predicts a parallel reduction of price dispersion within sectors. Our conceptual framework allows us to disentangle the effects of technology and freeness of entry from those of accessibility. On the one hand, by controlling for the impact of trade frictions, we are able to construct an index of ‘revealed competitiveness’, which would drive the relative performance of countries in an ideal world in which all faced the same barriers to international transactions. On the other hand, by focusing on the role of accessibility while keeping ‘revealed competitiveness’ as given, we are able to evaluate the impacts of EMU and enlargement on the competitiveness of European firms. We find that EMU positively affects the competitiveness of firms located in participating economies. Enlargement has, instead, two contrasting effects. It improves the accessibility of EU members but it also increases substantially the relative importance of unproductive competitors from Eastern Europe. JEL Classification: F12, R13.

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.

Does Qualification Drive Innovation? A Microeconometric Analysis Using Linked-employer-employee Data
Bianca Brandenburg, Jutta Günther, Lutz Schneider
IWH Discussion Papers,
No. 10,
2007
Abstract
Degree-level science and engineering skills as well as management and leadership skills are often referred to as a source of innovative activities within companies. Broken down by sectoral innovation patterns, this article examines the role of formal education and actual occupation for product innovation performance in manufacturing firms within a probit model. It uses unique micro data for Germany (LIAB) that contain detailed information about innovative activities and the qualification of employees. We find significant differences of the human capital endowment between sectors differentiated according to the Pavitt classification. Sectors with a high share of highly skilled employees engage in product innovation above average (specialized suppliers and science based industries). According to our hitherto estimation results, within these sectors the share of highly skilled employees does not, however, substantially increase the probability to be an innovative firm.

Systematic Mispricing in European Equity Prices?
Marian Berneburg
IWH Discussion Papers,
No. 6,
2007
Abstract
One empirical argument that has been around for some time and that clearly contra- dicts equity market efficiency is that market prices seem too volatile to be optimal estimates of the present value of future discounted cash flows. Based on this, it is deduced that systematic pricing errors occur in equity markets which hence can not be efficient in the Effcient Market Hypothesis sense. The paper tries to show that this so-called excess volatility is to a large extend the result of the underlying assumptions, which are being employed to estimate the present value of cash flows. Using monthly data for three investment style indices from an integrated European Equity market, all usual assumptions are dropped. This is achieved by employing the Gordon Growth Model and using an estimation process for the dividend growth rate that was suggested by Barsky and De Long. In extension to Barsky and De Long, the discount rate is not assumed at some arbitrary level, but it is estimated from the data. In this manner, the empirical results do not rely on the prerequisites of sta- tionary dividends, constant dividend growth rates as well as non-variable discount rates. It is shown that indeed volatility declines considerably, but is not eliminated. Furthermore, it can be seen that the resulting discount factors for the three in- vestment style indices can not be considered equal, which, on a risk-adjusted basis, indicates performance differences in the investment strategies and hence stands in contradiction to an efficient market. Finally, the estimated discount rates under- went a plausibility check, by comparing their general movement to a market based interest rate. Besides the most recent data, the estimated discount rates match the movements of market interest rates fairly well.

Interregional equalization policy in focus: Donor regions and beneficiary regions and their economic performance

Abstract
Die Zukunft interregionaler Ausgleichspolitik wird derzeit intensiv diskutiert. Während in der Vergangenheit das Interesse der Ausgleichspolitik primär den Nehmerregionen und den dort erzielten Wirkungen galt, richtet sich neuerdings der Blick auch auf die „Geber“. Bei letzteren werden wachstumsdämpfende Entzugseffekte befürchtet, die angesichts rückläufiger gesamtwirtschaftlicher Wachstumsraten Anlaß böten, über die Zukunft der Ausgleichspolitik nachzudenken. Das IWH hat sich zusammen mit zwei Projektpartnern in diese Debatte durch eine Untersuchung eingebracht, die im Auftrag des Bundesamtes für Bauwesen und Raumordnung durchgeführt wurde. Im folgenden werden vom IWH gewonnene Befunde wiedergegeben, wie Nehmerund Geberregionen hinsichtlich ihrer Wirtschaftsleistung dastehen und welche Entwicklungsmuster sich im Zeitverlauf zeigen. Bezüglich des Niveaus der Wirtschaftsleistung, die am Bruttoinlandsprodukt (BIP) je Einwohner gemessen wurde, zeigt sich erwartungsgemäß, daß die Geberregionen, allesamt westdeutsche Regionen, im Zeitraum 1992-2003 ein überdurchschnittliches BIP je Einwohner aufweisen; die Nehmerregionen, und zwar sowohl die ost- als auch (weniger stark) die westdeutschen dagegen ein unterdurchschnittliches. Bezüglich der Entwicklung der Wirtschaftsleistung, die anhand der Veränderungen beim relativen BIP je Einwohner (BIP je Einwohner der betreffenden Region in Relation zum Bundesdurchschnitt) gemessen wurde, zeigt sich, daß die ostdeutschen Nehmerregionen zunächst stark aufholen konnten, sich dieser Aufholprozeß jedoch nach 1998 deutlich abgeschwächt hat. Spiegelbildlich hat sich der Vorsprung der Geberregionen gegenüber dem bundesdurchschnittlichen BIP je Einwohner verringert, d. h., deren relatives BIP pro Kopf ging insgesamt zurück. Absolut gesehen stieg es jedoch. Eine ganze Reihe ostdeutscher Regionen, die 1992-1998 wachstumsstark waren, konnte diese Entwicklung danach nicht fortsetzen. Umgekehrt gehörte eine größere Zahl westdeutscher Regionen, die 1992-1998 ein stagnierendes oder rückläufiges relatives BIP je Einwohner aufwiesen, danach wieder zu den wachstumsstarken Räumen. Zusätzlich wurden die Beiträge der Regionen zum absoluten Zuwachs des BIP im Zeitraum 1998-2003 ermittelt: 30 von 271 Regionen erbringen etwa die Hälfte des gesamtwirtschaftlichen BIP-Zuwachses, davon sind 28 in Westdeutschland gelegen, 21 von ihnen sind Geberregionen. Dies spricht dafür, daß die Politik dafür sorgen sollte, den Regionen, die am meisten zur Zunahme der gesamtwirtschaftlichen Leistung beitragen (und damit die wirtschaftlichen Grundlagen für die interregionale Ausgleichspolitik schaffen), weiterhin günstige Entwicklungsbedingungen zu sichern.

Measurement Matters — Alternative Input Price Proxies for Bank Efficiency Analyses
Michael Koetter
Journal of Financial Services Research,
No. 2,
2006
Abstract
Most bank efficiency studies that use stochastic frontier analysis (SFA) employ each bank’s own implicit input price when estimating efficient frontiers. But at the same time, most studies are based on cost and/or profit models that assume perfect input markets. Traditional input price proxies therefore contain at least substantial measurement error. We suggest here two alternative input market definitions to approximate exogenous input prices. We have access to Bundesbank data, which allows us to cover virtually all German universal banks between 1993 and 2003. The use of alternative input price proxies leads to mean cost efficiency that is significantly five percentage points lower compared to traditional input prices. Mean profit efficiency is hardly affected. Across models, small cooperative banks located in large western states perform best while large banks and those located in eastern states rank lowest.
