Network Investment and the Threat of Regulation – Preventing Monopoly Exploitation or Infrastructure Construction?

IWH Discussion Papers,
No. 7,

Abstract
In summer 2005, the German telecommunication incumbent Deutsche Telekom announced its plans to build a new broadband fibre optics network. Deutsche Telekom decided as precondition for this new network not to be regulated with respect to pricing and third party access. To develop a regulator's strategy that allows investments and prevents monopolistic prices at the same time, we model an incumbent's decision problem under a threat of regulation in a game-theoretical context. The decision whether to invest or not depends on the probability of regulation and its assumed impact on investment returns. Depending on the incumbent's expectation on these parameters, he will decide if the investment is favourable, and which price to best set. This price is below a non-regulated profit maximising price, since the incumbent tries to circumvent regulation. Thus, we show that the mere threat of a regulator's intervention might prevent supernormal profits without actual price regulation. The regulator, on the other hand, can influence both investment decision and the incumbent's price via his signals on regulation probability and price. These signals an be considered optimal, if they simultaneously allow investment and minimize the incumbent's price.

Progressivity and Flexibility in Developing an Effective Competition Regime: Using Experiences of Poland, Ukraine, and South Africa for developing countries
Franz Kronthaler, Johannes Stephan
IWH Discussion Papers,
No. 6,
2006
Abstract
The paper discusses the role of the concept of special and differential treatment in the framework of regional trade agreements for the development of a competition regime. After a discussion of the main characteristics and possible shortfalls of those concepts, three case countries are assessed in terms of their experience with progressivity, flexibility, and technical and financial assistance: Poland was led to align its competition laws to match the model of the EU. The Ukraine opted voluntarily for the European model, this despite its intense integration mainly with Russia. South Africa, a developing country that emerged from a highly segregated social fabric and an economy dominated by large conglomerates with concentrated ownership. All three countries enacted (or comprehensively reformed) their competition laws in an attempt to face the challenges of economic integration and catch up development on the one hand and particular social problems on the other. Hence, their experience may be pivotal for a variety of different developing countries who are in negotiations to include competition issues in regional trade agreements. The results suggest that the design of such competition issues have to reflect country-particularities to achieve an efficient competition regime.

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.

New orientations for the German spatial development policy? Report about a workshop with the IWH
Gerhard Heimpold
Wirtschaft im Wandel,
No. 2,
2006
Abstract
Seit kurzem ist eine intensive Diskussion zur Frage im Gange, ob es bei der Raumentwicklungspolitik, also bei Politikmaßnahmen, mit denen bestimmte Regionen gezielt unterstützt werden, eine Neuorientierung zugunsten wachstumsstarker Regionen geben sollte. Daran schließt sich dann die zweite Frage an, ob und welche Unterstützung künftig die strukturschwachen, peripher gelegenen Regionen erhalten sollten. Die knappen öffentlichen Kassen, der verschärfte Wettbewerb der Regionen in Europa und die veränderten Bedingungen für die öffentliche Daseinsvorsorge in Räumen mit dramatischen Bevölkerungsrückgängen drängen nach Antworten auf die genannten Fragen. Das IWH bearbeitet zusammen mit der Gesellschaft für Finanz- und Regionalanalysen (GEFRA), Münster, und dem Leibniz Institut für Regionalentwicklung und Strukturplanung (IRS), Erkner, im Auftrag des Bundesamtes für Bauwesen und Raumordnung ein Forschungsprojekt zum Thema „Bundesstaatliche Ordnung und Bedeutung finanzieller Ausgleichssysteme für die Raumordnung“, das empirische Fundierungen zur Beantwortung der o. g. Fragen liefern soll. In der ersten Phase der Projektbearbeitung fand am 21. Juni 2005 ein Workshop statt, der den politischen Status quo räumlicher Ausgleichspolitik und eine Bestandsaufnahme vorliegender Forschungsergebnisse zum Gegenstand hatte. Eine stärkere Orientierung auf die wachstumsstarken Räume könnte bedeuten, an dort gegebenen Agglomerationsvorteilen anzuknüpfen bzw. Agglomerationsnachteile zu mildern. Für die Unterstützung von Agglomerationseffekten, denen in modernen regionalökonomischen Theorien große Bedeutung als Entwicklungsdeterminante beigemessen wird, liefert allerdings die empirische Forschung bislang wenig Hinweise, die in konkrete regionalpolitische Maßnahmen umzusetzen wären. Es wurde grundsätzlich von den meisten Referenten und Teilnehmern betont, daß auch bei einer stärkeren Hinwendung zu einer wachstumsorientierten Raumentwicklungspolitik die strukturschwachen peripheren Räume nicht ihrem Schicksal überlassen werden dürften. Die Zentren müssten Verantwortung für die schwächere Peripherie übernehmen, den schwachen Regionen sollte Hilfe zur Selbsthilfe gewährt werden, und ein Überdenken der Daseinsvorsorge in Räumen mit starkem Bevölkerungsrückgang wird unvermeidlich sein.

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.

Measuring the Efficiency of Regional Innovation Systems – An Empirical Assessment
Michael Fritsch, Viktor Slavtchev
Freiberg Working Papers, Nr. 08-2006,
No. 8,
2006
Abstract
Wir messen die Effizienz der regionalen Innovationssysteme (RIS) in Deutschland anhand einer Wissensproduktionsfunktion. Diese Funktion stellt einen Zusammenhang zwischen der Anzahl der von den Einwohnern einer Region angemeldeten Patente und der Anzahl der FuE-Beschäftigten im Privatsektor in der Region. Zwei alternative Methoden zur empirischen Berechnung der Wissensproduktionsfunktion werden vorgestellt. In einem ersten Ansatz nehmen wir an, dass sich Unterschiede der Produktivität der FuE-Beschäftigten in der Steigung der Wissensproduktionsfunktion und somit in der Grenzproduktivität der FuE-Aktivitäten niederschlagen. Ein zweiter Ansatz bestimmte die Durchschnittsproduktivität der FuE-Beschäftigten mittels einer stochastischen Frontier-Wissensproduktionsfunktion. Wir vergleichen die Resultate beider Ansätze und diskutieren kritische Fragen hinsichtlich der Verteilungscharakteristika der technischen Effizienz von Regionen, der adäquaten Größe regionaler Innovationssysteme sowie der Präsenz und der Effekte räumlicher Interdependenzen zwischen den Regionen (räumlicher Autokorrelation).

Abstract
Foreign subsidiaries of multinational companies are suggested as one of the main channels of technology transfer to less developed economies. In Central East Europe their presence proved to be a decisive factor to economic restructuring and development. This volume is a unique guide to theory, method of research, and empirical evidence, for technology transfer via foreign subsidiaries of multinational companies. It combines the merits of a core text on technology transfer via FDI with up-to-date empirical evidence.
