A glimpse on sectoral convergence of productivity levels

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.

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.

Economic Development in Saxony-Anhalt: empirical results and policy recommendations

No. 3,
2001
Abstract
Though the basic economic problems are still of the same kind all over East Germany, partially considerable regional differences exist in respect to the conditions for further economic development. Therefore, detailed empirical analyses for the individual Länder and their sub-regions are necessary making economic policy recommendations. The following contribution deals with this task taking Saxony-Anhalt as an example.
A multitude of indicators is used to bring out the specific strengths and weaknesses of the economy of this state (Land) and its sub-regions. The outstanding strength of Saxony-Anhalt are the high private investment outlays which served to build a modern capital stock during the past ten years. Another fundamental strength of the Land are the universities and public research institutions. Besides these unambiguous strengths some ‘ambivalent’ growth factors exist which are characterized by strengths as well as by weaknesses. Such ‘ambivalent’ growth factors are the infrastructure and the situation of important sectors and branches of economic activity. The weaknesses of Saxony-Anhalt’s economic structure find expression especially in its low supply with human capital and entrepreneurial initiative as well as in the few research and development efforts of its firms.
The aforementioned strengths of the Land are reflected insufficiently in its economic output. Consequently some economic policy measures are proposed to bring about an improvement: Amongst other things Saxony-Anhalt should develop a clear idea of its economic development (Leitbild). Such a Leitbild could be related to the Land’s strengths or to the elimination of its major weaknesses. This also would facilitate a concentrated use of the different economic policy instruments. The latter shouldn’t only be concentrated on singular economic growth factors but also spatially, on the economically stronger sub-regions, as this can lead to larger growth effects for the entire Land. The good provision with public research institutions in Saxony-Anhalt should be used to bring about an improvement of the economic structure to a larger extent than until now. This could be done for example by means of a further strengthening of applied research vs. basic research, possibly via orienting the public research more towards the existing branches of economic activity. Finally, the Land should intensify its efforts to increase the entrepreneurial initiative in Saxony-Anhalt, e. g. by means of introducing courses in economics in its schools.

Human capital in transformation – The example of the new Länder
Ralf Müller
IWH Discussion Papers,
No. 126,
2000
Abstract
The human capital of a nation is highly correlated to its productivity. Thus, differences in human capital may be seen as one factor determining the productivity gap between East and West Germany. However, a disadvantage of East Germany with regard to hu-man capital only shows up as long as it concerns skills that are built up on the job, i.e., by learning by doing; even more, this disadvantage has been decreasing in the 1990's. In contrast, as long as it concerns skills that have been acquired through formal education, East Germany has a high level of human capital in comparison to West Germany. In general, the problem of East Germany’s human capital proves to be rather demand-sided. It may be due to East Germany’s low skill-intensive industry structure.

Is there a real world interest rate?
Christian Dreger, Christian Schumacher
Wirtschaft im Wandel,
No. 12,
2000
Abstract
The article examines the validity of real interest parity as a long run condition for the G7 countries. According to the hypothesis, differences of real interest rates are stationary. The hypothesis is supported by the means of panel unit root tests. Compared with standard unit root tests, these procedures rely on a broader long run information set and are better suited to detect a false null hypothesis.

Incentive effects of unemployment benefits on job searches
Hilmar Schneider, Olaf Fuchs
Wirtschaft im Wandel,
No. 11,
2000
Abstract
Economic theory predicts that an anticipated cut of the replacement ratio in the future affects the search intensity at all dates previous to the cut. This effect is illustrated by simulating the dynamics of the reservation wage for different time profiles of the replacement ratio with a simple calibrated search model.

2000
Abstract
Based on the IAB Company Panel, the significance of the different scales of enterprises for the investment intensity in the East German industry was tested. There is a positive correlation. For example the intensity of investment in large-scale enterprises is double what it is in small-scale enterprises.

Efficiency of qualification and job creating measures in East Germany
Annette Bergemann, Birgit Schultz
Wirtschaft im Wandel,
No. 9,
2000
Abstract
This paper evaluates job creation schemes and further training in East Germany for the period 1990-1998. We identify the causal effect of the treatment-on-the-treated by a two-step procedure: First, we apply the matching technique based on estimated propensity scores. Secondly, we use the Difference-in-Differences estimator. Hereby, we take especially consideration on Ashenfelter s Dip, which characterize a significant decrease in the participants employment shortly before the start of a program. This can be assumed to be related to the anticipation of the participation.
