Abstract
We estimate the effect of internet penetration on retail bank margins in the euro area. Based on an adapted Baumol [1982] type contestability model, we argue that the internet has reduced sunk costs and therefore increased contestability in retail banking. We test this conjecture by estimating the model using semi-aggregated data for a panel of euro area countries. We utilise time series and cross-sectional variation in internet penetration. We find support for an increase in contestability in deposit markets, and no effect for loan markets. The paper suggests that for time and savings deposits, the presence of brick and mortar bank branches may no longer be of first order importance for the assessment of the competitive structure of the market.

The Stability of Bank Efficiency Rankings when Risk Preferences and Objectives are Different
Michael Koetter
European Journal of Finance,
No. 2,
2008
Abstract
We analyze the stability of efficiency rankings of German universal banks between 1993 and 2004. First, we estimate traditional efficiency scores with stochastic cost and alternative profit frontier analysis. Then, we explicitly allow for different risk preferences and measure efficiency with a structural model based on utility maximization. Using the almost ideal demand system, we estimate input- and profit-demand functions to obtain proxies for expected return and risk. Efficiency is then measured in this risk-return space. Mean risk-return efficiency is somewhat higher than cost and considerably higher than profit efficiency (PE). More importantly, rank–order correlation between these measures are low or even negative. This suggests that best-practice institutes should not be identified on the basis of traditional efficiency measures alone. Apparently, low cost and/or PE may merely result from alternative yet efficiently chosen risk-return trade-offs.

Abstract
Real costs of freight transportation have strong increased in Russia particularly during the period of price liberalization 1992–93. This paper investigates possible connections between rising transport costs and the evolution of the size structure of the system of cities in the Russian Federation and its federal subjects. Empirical findings suggest that under conditions of a closed system agglomeration processes according to the predictions of the model of Tabuchi et al. (2005) would have taken place especially in the periphere regions of the North and Far East.

FDI and Domestic Investment: An Industry-level View
Claudia M. Buch
CEPR. Discussion Paper No. 6464,
2007
Abstract
Previous empirical work on the link between domestic and foreign investment provides mixed results which partly depend on the level of aggregation of the data. We argue that the aggregated home country implications of foreign direct investment (FDI) cannot be gauged using firm-level data. Aggregated data, in turn, miss channels through which domestic and foreign activities interact. Instead, industry-level data provide useful information on the link between domestic and foreign investment. We theoretically show that the effects of FDI on the domestic capital stock depend on the structure of industries and the relative importance of domestic and multinational firms. Our model allows distinguishing intra-sector competition from inter-sector linkage effects. We test the model using data on German FDI. Using panel cointegration methods, we find evidence for a positive long-run impact of FDI on the domestic capital stock and on the stock of inward FDI. Effects of FDI on the domestic capital stock are driven mainly by intra-sector effects. For inward FDI, inter-sector linkages matter as well.

Exploring the International Linkages of the Euro Area: A Global VAR Analysis
Stéphane Dées, Filippo di Mauro, M. Hashem Pesaran, Vanessa Smith
Journal of Applied Econometrics,
No. 1,
2007
Abstract
Abstract This paper presents a quarterly global model combining individual country vector error-correcting models in which the domestic variables are related to the country-specific foreign variables. The global VAR (GVAR) model is estimated for 26 countries, the euro area being treated as a single economy, over the period 1979?2003. It advances research in this area in a number of directions. In particular, it provides a theoretical framework where the GVAR is derived as an approximation to a global unobserved common factor model. Using average pair-wise cross-section error correlations, the GVAR approach is shown to be quite effective in dealing with the common factor interdependencies and international co-movements of business cycles. It develops a sieve bootstrap procedure for simulation of the GVAR as a whole, which is then used in testing the structural stability of the parameters, and for establishing bootstrap confidence bounds for the impulse responses. Finally, in addition to generalized impulse responses, the current paper considers the use of the GVAR for ?structural? impulse response analysis with focus on external shocks for the euro area economy, particularly in response to shocks to the US.

A Game Theoretic Analysis of the Conditions of Knowledge Transfer by New Employees in Companies
Sidonia vonLedebur
IWH Discussion Papers,
No. 3,
2006
Abstract
The availability of knowledge is an essential factor for an economy in global competition. Companies realise innovations by creating and implementing new knowledge. Sources of innovative ideas are partners in the production network but also new employees coming from another company or academia. Based on a model by HECKATHORN (1996) the conditions of efficient knowledge transfer in a team are analysed. Offering knowledge to a colleague can not be controlled directly by the company due to information asymmetries. Thus the management has to provide incentives which motivate the employees to act in favour of the company by providing their knowledge to the rest of the team and likewise to learn from colleagues. The game theoretic analysis aims at investigating how to arrange these incentives efficiently. Several factors are relevant, especially the individual costs of participating in the transfer. These consist mainly of the existing absorptive capacity and the working atmosphere. The model is a 2x2 game but is at least partly generalised on more players. The relevance of the adequate team size is shown: more developers may increase the total profit of an innovation
(before paying the involved people) but when additional wages are paid to each person a greater team decreases the remaining company profit. A further result is
that depending on the cost structure perfect knowledge transfer is not always best for the profit of the company. These formal results are consistent with empirical studies to the absorptive capacity and the working atmosphere.

Determinants of employment - the macroeconomic view
Christian Dreger, Heinz P. Galler, Ulrich (eds) Walwai
Schriften des IWH,
No. 22,
2005
Abstract
The weak performance of the German labour market over the past years has led to a significant unemployment problem. Currently, on average 4.5 mio. people are without a job contract, and a large part of them are long-term unemployed. A longer period of unemployment reduces their employability and aggravates the problem of social exclusion.
The factors driving the evolution of employment have been recently discussed on the workshop Determinanten der Beschäftigung – die makroökonomische Sicht organized jointly by the IAB, Nuremberg, and the IWH, Halle. The present volume contains the papers and proceedings to the policy oriented workshop held in November 2004, 15-16th. The main focus of the contributions is twofold. First, macroeconomic conditions to stimulate output and employment are considered. Second, the impacts of the increasing tax wedge between labour costs and the take home pay are emphasized. In particular, the role of the contributions to the social security system is investigated.
In his introductory address, Ulrich Walwei (IAB) links the unemployment experience to the modest path of economic growth in Germany. In addition, the low employment intensity of GDP growth and the temporary standstill of the convergence process of the East German economy have contributed to the weak labour market performance. In his analysis, Gebhard Flaig (ifo Institute, München) stresses the importance of relative factor price developments. A higher rate of wage growth leads to a decrease of the employment intensity of production, and correspondingly to an increase of the threshold of employment. Christian Dreger (IWH) discusses the relevance of labour market institutions like employment protection legislation and the structure of the wage bargaining process on the labour market outcome. Compared to the current setting, policies should try to introduce more flexibility in labour markets to improve the employment record. The impact of interest rate shocks on production is examined by the paper of Boris Hofmann (Deutsche Bundesbank, Frankfurt). According to the empirical evidence, monetary policy cannot explain the modest economic performance in Germany. György Barabas and Roland Döhrn (RWI Essen) have simulated the effects of a world trade shock on output and employment. The relationships have been fairly stable over the past years, even in light of the increasing globalization. Income and employment effects of the German tax reform in 2000 are discussed by Peter Haan and Viktor Steiner (DIW Berlin). On the base of a microsimulation model, household gains are determined. Also, a positive relationship between wages and labour supply can be established. Michael Feil und Gerd Zika (IAB) have examined the employment effects of a reduction of the contribution rates to the social security system. To obtain robust results, the analysis is done under alternative financing scenarios and with different macroeconometric models. The impacts of allowances of social security contributions on the incentives to work are discussed by Wolfgang Meister and Wolfgang Ochel (ifo München). According to their study, willingness to work is expected to increase especially at the lower end of the income distribution. The implied loss of contributions could be financed by higher taxes.

East German engineering 2002: milestone break-even reached

Wirtschaft im Wandel,
No. 7,
2005
Abstract
Der ostdeutsche Maschinenbau verlor im Zuge des marktwirtschaftlichen Umbaus seine einst führende Rolle in der Industrie Mittel- und Ostdeutschlands. Weitgehend ohne Unterstützung durch westdeutsche und ausländische Mutterunternehmen und erschwert durch die lang anhaltende Investitionsschwäche in der ersten Hälfte der 1990er Jahre nahm die Umstrukturierung mehr Zeit als in anderen Industriebranchen in Anspruch und führte zu tiefen Einschnitten bei Produktion und Beschäftigung. In der Privatisierungsphase wurden mit der Konzentration auf das Kerngeschäft die Fertigungstiefe verringert und die Beschäftigtenzahl reduziert. Verstärkt wurde der Personalabbau durch die Politik der schnellen Lohnangleichung. Mit der Etablierung und Entwicklung der Unternehmen auf privater Grundlage erhöhte sich die Fertigungstiefe wieder und die Vorleistungskosten wurden anteilmäßig gesenkt. Ein deutlich geschrumpfter Bestand an kleinen und mittleren Unternehmen erreichte erst im Jahr 2002 das Etappenziel des marktwirtschaftlichen Umbaus, die Gewinnzone; 2003 stieg die Rendite weiter an. Bei der Rendite besteht noch ein Rückstand gegenüber Maschinenbauern im früheren Bundesgebiet, wenngleich die wenigen größeren Unternehmen besser abschneiden als ihre westdeutschen Wettbewerber. Der einstige Schlüsselsektor in der DDR bietet heute 58 600 Beschäftigten Arbeit, das entspricht 10% des Standes am Ende der DDR. Er rangiert nun deutlich hinter dem umsatzstärksten Zweig in Ostdeutschland, dem Ernährungsgewerbe. Seine Bedeutung für Produktion und Beschäftigung insgesamt ist gering.

Employment effects of development of renewable energies
Steffen Hentrich, Jürgen Wiemers, Joachim Ragnitz
IWH-Sonderhefte,
No. 1,
2004
Abstract
Die Bundesregierung strebt bis zum Jahr 2010 eine Verdopplung des Anteils erneuerbarer Energien am Primärenergie- sowie am Bruttostromverbrauch an. Das vorrangige Ziel der damit verbundenen Umstrukturierung des Energiesektors ist die Verbesserung der Umweltqualität. Es darf jedoch nicht außer Acht gelassen werden, dass die Förderung erneuerbarer Energien zwangsläufig auch gesamtwirtschaftliche Auswirkungen hat. Angesichts der anhaltend angespannten Lage am Arbeitsmarkt stehen dabei insbesondere die Beschäftigungseffekte der Förderung erneuerbarer Energien im Mittelpunkt des öffentlichen und wirtschaftspolitischen Interesses.

Diversifikation und regionale Wirtschafts- und Beschäftigungsentwicklung - Eine empirische Analyse für ausgewählte deutsche Gebiete
Peter Haug
Jahrbuch für Regionalwissenschaft,
No. 2,
2004
Abstract
Der Beitrag untersucht die Auswirkungen einer heterogenen Wirtschaftsstruktur auf die langfristige Beschäftigungsentwicklung einer Region. Es wird anhand eines einfachen mikroökonomischen Modells unter Unsicherheit illustriert, dass sowohl für private Haushalte als auch für Unternehmen die Ansiedlung in wirtschaftlich diversifizierteren Regionen aufgrund der damit verbundenen Versicherungsfunktion (Verringerung des Einkommensrisikos, Verringerung der Einstellungskosten im weitesten Sinne) für Arbeitgeber und Arbeitnehmer vorteilhaft sein kann. Die ökonomischen Schätzergebnisse für niedersächsische Kommunen deuten auf einen positiven Zusammenhang zwischen Diversifikation der lokalen Wirtschaft und der Beschäftigungssituation hin, und zwar sowohl auf der Ebene der aggregierten Arbeitskräftenachfrage einer Gemeinde, als auch für die Beschäftigung der meisten Wirtschaftszweige.
