A glimpse on sectoral convergence of productivity levels
Gerald Müller
IWH Discussion Papers,
No. 133,
2001
Abstract
This paper examines the presence of sectoral convergence of labor productivity between 14 OECD countries. Using the OECD International Sectoral Data Base (ISDB), the paper looks at the developments within 12 distinct sectors during the period 1970-1995. The change of the coefficients of variance suggests that there is strong sectoral convergence within most service sectors while the evidence of convergence for Manufacturing as well as for Communication is rather weak. These findings are in line with most studies undertaken on this subject so far. It is concluded that economic theories at hand to explain growth and convergence (or divergence respectively) are of different importance for the sectors concerned. While models of the New Growth Theory seemed to be useful to explain growth mechanisms within Manufacturing and Communication, traditional models seemed to apply to most other sectors.

Bank Relationships and Firm Profitability

Abstract
This paper examines how bank relationships affect firm performance. An empirical implication of recent theoretical models is that firms maintaining multiple bank relationships are less profitable than their single-bank peers. We investigate this empirical implication using a data set containing virtually all Norwegian publicly listed firms for the period 1979-1995. We find that profitability is substantially higher if firms maintain only a single bank relationship. We also find that firms replacing a single bank relationship are on average smaller and younger than firms not replacing a single bank relationship.

Considerable demand for research on evaluation of labor market policy measures: The example of pick up effects with respect to structural adjustment measures for East German enterprises

Abstract
Obwohl beträchtliche Mittel in die aktive Arbeitsmarktpolitik fließen, fehlt es bislang an einer systematischen Evaluierung der arbeitsmarktpolitischen Instrumente. Dies liegt primär an der Unzugänglichkeit geeigneter Daten. Am Beispiel der Mitnahmeeffekte bei Strukturanpassungsmaßnahmen für ostdeutsche Wirtschaftsunternehmen werden exemplarisch die Probleme aufgezeigt, die aus der prekären Datenlage entstehen.

Abstract
Der Beitrag untersucht die gesamtwirtschaftlichen Rückwirkungen der aktuellen Ölpreissteigerungen. Dabei werden verschiedene Szenarien hinsichtlich der Preisentwicklung betrachtet. Die Analyse zeigt, dass die Produktions- und Beschäftigungsverluste höherer Ölpreise nicht an die Krisen der siebziger Jahre heranreichen und relativ moderat bleiben.

Wage and income subsidies in East Germany: Doubtful prospects of success

No. 13,
2000
Abstract
Es werden verschiedene Kombilohnstrategien auf ihre Effekte bezüglich Erwerbsbereitschaft und fiskalischen Kosten potenzieller Niedriglohnbezieher in Ostdeutschland hin untersucht. Eine methodische Besonderheit des mikroökonometrischen Arbeitsangebotsmodells bildet die Berücksichtigung nichtkonvexer Budgetmengen, wie sie durch die Transferentzugsraten des Steuer- und Transfersystems hervorgerufen werden. Darüber hinaus wird ein nichtlinearer Einfluss des Lohnes auf das Arbeitsangebot unterstellt. Es zeigt sich, dass im Rahmen von insgesamt bescheidenen Arbeitsmarkteffekten eine Konzentration der Subventionen auf begrenzte Zielgruppen (z.B. Langzeitarbeitslose) erfolgversprechender bezüglich der eingesetzten Mittel erscheint als eine breite Streuung.

Incentive effects of unemployment benefits on job searches

Abstract
Mit Hilfe einer modelltheoretischen Analyse wird untersucht, wie sich das zeitliche Profil der Höhe der Lohnersatzleistungen auf die Suchstrategie eines Arbeitslosen auswirkt. Es wird gezeigt, dass eine antizipierte Absenkung nach einer bestimmten Dauer der Arbeitslosigkeit schon zu Beginn der Arbeitslosigkeit das Akzeptanzlohnniveau senkt und somit die Wahrscheinlichkeit einer Arbeitsaufnahme erhöht. Beim faktischen Eintritt der Absenkung erfolgt deshalb nur noch eine vergleichsweise geringe Absenkung des Akzeptanzlohnniveaus.

Environmental policy under product differentiation and asymmetric costs - Does leapfrogging occur and is it worth it?
Jacqueline Rothfels
IWH Discussion Papers,
No. 124,
2000
Abstract
This paper studies the influence of environmental policies on environmental quality, domestic firms, and welfare. Point of departure is Porter’s hypothesis that unilateral environmental regulation may enhance the competitiveness of domestic firms. This hypothesis has recently received considerable support in theoretical analyses, especially if imperfectly competitive markets with strategic behavior on behalf of the agents are taken into account. Our work contributes to this literature by explicitely investigating the implications of asymmetric cost structures between a domestic and a foreign firm sector. We use a partial-equilibrium model of vertical product differentiation, where the consumption of a product causes environmental harm. Allowing for differentiated products, the domestic industry can either assume the market leader position or lag behind in terms of the environmental quality of the produced product. Assuming as a benchmark case that the domestic industry lags behind, we investigate the possibility of the government to induce leapfrogging of the domestic firm, i.e. a higher quality produced by the domestic firm after regulation than that of the competitor prior to regulation. It is shown that in the case of a cost advantage for the domestic firm in the production process the imposition of a binding minimum quality standard can serve as a tool to induce leapfrogging. In case of a cost disadvantage the same result can be achieved through an adequate subsidization of quality dependend production costs. Thus, careful regulation enables the domestic firm in both scenarios to better its competitive position against foreign competitors and to earn larger profits. Additionally, environmental quality and welfare can be enhanced.
