Abstract
Innovations in the sense of new products and production processes are crucial drivers of the economic development in advanced economies. After a phase of massive technological renewal in East Germany, characterized by much a higher rate of innovators in East than in West Germany, firms in East Germany have to compete with original innovation activities. The paper outlines the innovation activity in East and West Germany and investigates the determinants of product and process innovation within a multivariate analysis using the IAB establishment panel.
The empirical study shows that firms in manufacturing industry in East Germany are quite active in innovation activities in the year 2008. As regards the share of innovative firms there are no substantial differences between East and West Germany. The regression analysis shows that R&D is a significant determinant of innovation in East and West for all types of innovation. In East Germany, further education activities for employees also show a statistically significant impact on innovation. A major difference between East and West could be found for the firm size. In East Germany size has no significant impact on innovation while in West Germany size clearly matters. Different from West Germany, small firms (10 up to 49 employees) in the East have a significantly positive impact on product innovations in the sense of market novelties.

Abstract
Employee participation via works councils is at the heart of the industrial relations in Germany. Despite considerable research, there is still no consensus on the effect works councils exert on establishment productivity. I estimate the statistical relationship between works council existence and establishment productivity using the most recent information from the IAB establishment panel and find that works council existence is related with a nine percent higher productivity. Based on the results of earlier studies, it is argued that the productivity effect of works councils exceeds the estimated statistical relationship.

Capital Stock Approximation using Firm Level Panel Data: A Modified Perpetual Inventory Approach
Steffen Müller
Jahrbücher für Nationalökonomie und Statistik,
No. 4,
2008
Abstract
Many recent studies exploring conditional factor demand or factor substitution issues use firm level panel data. A considerable number of establishment panels contains no direct information on the capital input, necessary for production or cost function estimation. Incorrect measurement of capital leads to biased estimates and casts doubt on any inference on output elasticities or input substitution properties. The perpetual inventory approach, commonly used for long panels, is a method that attenuates these problems. In this paper a modified perpetual inventory approach is proposed. This method provides more reliable measures for capital input when short firm panels are used and no direct information on capital input is available. The empirical results based on a replication study of Addison et al. (2006) support the conclusion that modified perpetual inventory is superior to previous attempts in particular when fixed effects estimation techniques are used. The method thus makes a considerable number of recently established firm panels accessible to more sophisticated production function or factor demand analyses.

Research and Development: important source for product innovation also in East Germany

Wirtschaft im Wandel,
No. 9,
2007
Abstract
The development and successful introduction of new products is a fundamental feature of a modern knowledge society. After completion of the retrieving technological renewals in East Germany, businesses in the newly-formed German states have to stand up to the competition for marketable concepts and ideas. In doing so, the structural particularities on the strength of transformation are still in force and besides, the embedding of East Germany between high-tech in the West and catching up countries in the East constitutes an additional challenge. This article outlines the innovation activities of East German companies and pursues in the framework of an multivariate analysis to follow up intra-corporate determining factors for product innovations The empirical analysis, employing the IAB establishment panel, shows an active share of innovation participation of companies belonging to the manufacturing industry in East Germany during the years 2002 and 2003. The proportion of companies with product innovation in the newly-formed German states even lies slightly above the reference value for West Germany. Especially companies with an own Research and Development (R&D) department are introducing new products twice as much as companies without an R&D division. The regression analysis proves that own R&D represents the strongest driving force for product innovations in regard to input factors. Moreover, continuing operational education can also be attested a positive impact on innovation activities and emphasizes concurrently the meaning of long-life learning. In reference to business specific characteristics, it stands out that foreign equity participation imposes a significant negative impact of on product innovations. This result, deserving further analysis, indicates the phenomenon of so-called subcontracting.

The State of Convergence in SADC
Tobias Knedlik, F. Povel
Monitoring Regional Integration in Southern Africa Yearbook, Vol. 7,
No. 7,
2007
Abstract
The Southern African Development Community (SADC) Treaty established an integration agenda for the grouping culminating in the introduction of a common currency by 2018. By determining the degree of macroeconomic convergence across countries it becomes possible to draw conclusions with respect to the feasibility of the envisaged integration agenda of a regional integration scheme. In order to test for convergence among southern African countries the panel unit root test proposed by Im, Pesaran, and Shin (2003) is conducted. The results of the convergence analysis suggest that countries converge towards South Africa.

Mikroökonometrische Evaluation der ökonomischen Wirkungen betrieblicher Mitbestimmung - Möglichkeiten und Grenzen des Matching-Ansatzes

Jahrbücher für Nationalökonomie und Statistik,
No. 5,
2006
Abstract
The evaluation of economic effects of workers participation is not simple from the methodical point of view because of specific characteristics of establishments with works councils. Especially recent studies show contradictory results. In this study problems are pointed out, discussed, and options for solution are presented on the example of workers participation in East German establishments of industry and construction by the IAB-Establishment Panel.
An optimal matching-algorithm which supplies good matching-results for small samples to assign 'statistical establishment-twins' is applied. But by reason of very short primarily spells it can only calculate short time effects. Therefore, the matching method is additionally used to construct longer observation periods. By this new application establishments with recently founded works councils are matched with so called 'proxy establishments' with existing works councils. As a result short observation periods are prolonged and information about long-term effects can be given.
The effects on productivity, profitability and qualification level of employees show neither in short-term nor in long-term a significant impact on workers' participation.

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.
