Attribute Dependence and the Provision of Quality

Abstract
Often a quality improvement necessitates modifications of varietal product features. This paper studies firms’ incentives to provide quality when this decision affects the goods’ degree of perceived horizontal differentiation. We find that the quality level hinges crucially on the interaction between the quality and the varietal product attribute. We examine the outcome of a game where firms decide on quality and price relative to what a social planner would desire. If the interaction between quality and perceived horizontal differentiation is sufficiently positive, we find for the sequential game ‘quality then price’ that the private incentives to provide quality are excessive relative to the social optimum. As a result the level and the direction of interaction between the attributes determines whether there is excessive or insufficient provision of quality.

Methods of estimating the overall economic production potential and the productivity gap

No. 142,

Abstract
Für die wirtschaftspolitischen Instanzen stellt die Kenntnis des Produktionspotentials und des daraus abgeleiteten gesamtwirtschaftlichen Kapazitätsauslastungsgrades eine wichtige Orientierungsgröße dar. In diesem Diskussionspapier werden verschiedene Methoden der Schätzung des Produktionspotentials dargestellt. Diese umfassen Unternehmensbefragungen, reine Zeitreihenmethoden und Verfahren, die explizit die ökonomische Theorie berücksichtigen. Hier ist insbesondere der Produktionsfunktions-Ansatz zu nennen. Abschließend werden einige der vorgestellten Schätzmethoden auf Daten der Bundesrepublik Deutschland angewandt.

On the Incentives to Provide Fuel-Efficient Automobiles
Hans Degryse, Andreas Irmen
Journal of Economics,
No. 2,

Abstract
We argue that the provision of more fuel-efficient cars necessitates specific aerodynamic shapes. We show that the presence of this technological constraint may reduce the incentives to provide fuel efficiency. In equilibrium, cars become more similar and aerodynamic as fuel prices increase. However, the provided level of fuel efficiency falls short of the social optimal one such that a fuel-economy standard is welfare-enhancing.

Overall economic production in East Germany grows slightly despite international cyclical weakness

No. 7,

Abstract
The article deals with the economic development in East Germany up to the
year 2002. It is shown the strong influence of the capacity adjustments in construction
and state sectors on the economic growth. Moreover the article analyzes
in detail the chances and problems of the sectors “manufacturing“ and “construction“ with productivity and unit labor costs playing the central part in restoring their competetiveness.

Productivity gap of East German industry: A summarizing evaluation
Joachim Ragnitz
Wirtschaft im Wandel,
No. 7,
2001
Abstract
Ten years after German unification labor productivity in the New Laender reaches only 70 per cent of West German levels. Further, in the second half of the 1990ies, convergence did not continue. Because productivity can be regarded as a key for wages, for competitiveness of firms and for future transfer payments, the reasons for low productivity in East Germany are of major importance. In this article, it is argued that the existing productivity gap reflects mainly structural differences between East and West Germany, that is the high share of small firms and the predominance of sectors with low value added per worker. Additionally, difficulties on product markets leading to insufficient selling prices are responsible for the comparative low productivity of East German firms. Differences in capital intensity or in human capital, however, do explain only a small part of the productivity gap.

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.

Employment threshhold shows declining trend
Christian Dreger, Hans-Ulrich Brautzsch
Wirtschaft im Wandel,
No. 4,
2001
Abstract
The paper estimates Okuns law for countries of the eurozone using paneleconometric methods. Based on the results the minimum growth rate needed for a reduction in unemployment is calculated. In the period under investigation, the minimum growth rate has declined. Actually unemployment will be reduced through economic growth, and the minmum growth rates are lower than in the past. However growth must be accompanied by structural reforms in the labor market.

Differences in productivity and convergence of economic regions – The example of the New Länder -
Gerald Müller, Joachim Ragnitz, Anita Wölfl
IWH-Sonderhefte,
No. 3,
2001
Abstract
Auch im Jahre 2000 liegt das Produktivitätsniveau, das im Durchschnitt der ostdeutschen Wirtschaft erreicht wird, bei nur etwa zwei Dritteln des westdeutschen Wertes. Zwar gibt es eine erhebliche Differenzierung nach Unternehmen, nach Branchen und nach Regionen. Im Ganzen stellen die neuen Länder aber noch immer eine strukturschwache Region dar, und es ist offenkundig, dass das Ziel einer Angleichung der Pro-Kopf-Einkommen an das Westniveau kurzfristig nicht erreicht werden kann.
Die Frage, weshalb das Produktivitätsniveau in der ostdeutschen Wirtschaft weiterhin deutlich niedriger liegt als in Westdeutschland, ist auch 10 Jahre nach der deutschen Vereinigung noch nicht abschließend geklärt. In der Literatur gibt es zwar inzwischen eine ganze Reihe unterschiedlich gut begründeter Hypothesen, mit denen der Produktivitätsrückstand auf verschiedene betriebsinterne und -externe Faktoren zurückgeführt werden soll. Eine umfassende Gesamtdarstellung fehlt aber bislang noch. Auch die Frage, welche Schlussfolgerungen angesichts des anhaltend niedrigen Produktivitätsniveaus für den weiteren Konvergenzprozess zu ziehen sind, ist noch nicht überzeugend beantwortet.
Angesichts dieser Forschungsdefizite hat das Bundesministerium für Wirtschaft und Technologie mit Schreiben vom 29. April 1998 das Institut für Wirtschaftsforschung Halle beauftragt, im Rahmen der sektoralen Strukturberichterstattung das Thema „Produktivitätsunterschiede und Konvergenz von Wirtschaftsräumen – Das Beispiel der neuen Länder“ zu bearbeiten. Das IWH legt hiermit den Abschlussbericht zu diesem Projekt vor.
