INNOVATION AND EXPORT PERFORMANCE: ADJUSTMENT AND REMAINING DIFFERENCES IN EAST AND WEST GERMAN MANUFACTURING

Abstract

The economic situation in Germany 16 years after reunification is marked by the fading out of the adjustment process between East and West. This paper refers to this context analyzing the export behavior comparing firms in West and East Germany. Our estimates confirm a strong relationship between innovations and export performance as well as structural differences between East and West German firms. East German firms are less likely to export than firms in the West. Besides, West German medium technology firms are comparable in their export behavior to high tech firms while East German firms are more similar to the low technology sector. Labor productivity turns out to be more important in East Germany. We interpret these findings as a specialization of West German firms towards technologically-driven high-quality markets, whereas East German companies are faced with higher sunk costs and seem to operate more often in less dynamic, price-sensitive markets.     

EQUALITY OF OPPORTUNITY: EAST VS. WEST GERMANY

The case of German reunification has been subject to extensive research on earnings inequality and labour market integration. However, little is known about the development of equality of opportunity (EOp) in East and West Germany after 1990. Using German micro data, we empirically analyse how circumstances beyond the sphere of individual control relate to inequality in East and West Germany. Our results show that EOp is larger in East than in West Germany. However, despite increasing income inequality, EOp remained surprisingly constant.     

The East German wage structure after transition1

Abstract We extend the literature on transition economies’ wage structures by investigating the returns to tenure and experience. This study applies recent panel data and estimation approaches that control for hitherto neglected biases. We compare the life‐cycle structure of East and West German wages for fulltime employed men in the private sector. The patterns in the returns to seniority are similar for the two regional labour markets. The returns to experience lag behind in the East German labour market, even almost 20 years after unification, with significant differences particularly for high‐skill workers. The results are robust when only individuals who started their labour market career in the market economy are considered. We expect that the different returns are related to the heterogeneity of work experience gathered in East as compared with West Germany.     

RESEARCH AND DEVELOPMENT IN SMALL AND MEDIUM-SIZED ENTERPRISES: THE ROLE OF FINANCIAL CONSTRAINTS AND PUBLIC FUNDING

This paper presents microeconometric evidence on financing constraints for research and development activities in German small‐ and medium‐sized firms (SME). Special attention is paid to the role of public research and development (R&D) subsidies. For this purpose SMEs in West and East Germany are compared because these regions are very different in their supply of public R&D funding. The empirical evidence suggests that West German SMEs are financially constrained in their R&D activities by both internal and external resources. In East Germany, firms are not sensitive to external constraints, possibly due to high public R&D subsidies. The results show that R&D in East Germany is to a large extent driven by public subsidies and that the usual financial market mechanisms are dysfunctional with respect to R&D in this region.     

The role of social networks in determining migration and labour market outcomes

This paper empirically examines social network explanations for migration decisions in the context of German reunification. Using longitudinal data from the German Socio‐Economic Panel, we first show that the presence of a family in West Germany is an important predictor for the migration hazard rate of East Germans. We then explore whether pre‐migration networks have a discernible impact on the economic and social assimilation of East German immigrants in West Germany. We find that East German immigrants are more likely to be employed and to hold higher paying jobs when socially connected to the West prior to emigrating.     

Industrial Policy and the East German Productivity Puzzle

Catching-up of East German productivity to West German levels has completely faded out since the mid-1990s. The remaining productivity gap cannot be attributed to an inferior capital endowment or qualification deficiencies of the East German labor force. Instead, it appears to be the result of an inappropriate design of industrial policy which concentrated on the subsidization of physical capital and largely ignored the advance of human capital- and service-intensive industrial structures. East Germany will have to face another wave of painful structural adjustment when capital-intensive industries are no longer protected from competition by public subsidies.     

Wages in the East German Transition Process: Facts and Explanations

We analyze wage developments in the East German transition process both at the macro- and at the microeconomic level. At the macroeconomic level, we draw special attention to the important distinction between product and consumption wages, describe the development of various wage measures, labor productivity and unit labor costs in East Germany in relation to West Germany, and relate these developments to the system of collective wage bargaining. At the microeconomic level, we describe changes in the distribution of hourly wages between 1990 and 1997 and analyze the economic factors determining these changes by way of empirical wage functions estimated on the basis of the Socio-Economic Panel for East Germany. The paper also draws some conclusions on the likely future course of the East–West German wage convergence process.     

Is Part-Time Employment after Childbirth a Stepping-Stone into Full-Time Work? A Cohort Study for East and West Germany

Does part-time work support first-time mothers’ employment by providing a stepping-stone into full-time work in Germany? Using data from the German Socio-Economic Panel from 1984–2012, this study compares three different age cohorts of first-time East and West German mothers to investigate whether there has been any convergence between East and West Germany in the way women use part-time employment. Results show that mothers in West Germany in all cohorts tended to remain in part-time employment for longer periods than those in East Germany. Part-time employment more often provided a stepping-stone into full-time employment in East Germany than in West Germany. East German women who gave birth after reunification were less likely than older cohorts to experience a transition from part-time to full-time work. Thus, part-time employment not followed by subsequent full-time work has become more common in the East.     

Dynamic adjustment and long-run equilibria: Panel data estimates for the East German states

The economic development in East Germany after unification shows both, success and failure. In the early nineties wages and productivity increased fast; later on catching up faded out. A central question from a policy viewpoint is whether this fading out indicates a reduction of the adjustment speed or an equilibrium gap. This points towards a stationarity analysis of differences between East and West Germany. Our paper presents panel data estimates for the East German states for wages, productivity, competitiveness and unemployment. The results reveal that the adjustment was fast, but the equilibrium gaps are large.     

The East-West German gap in revenue productivity:Just a tale of output prices?

East German manufacturers’ revenue productivity is substantially below West German levels, even three decades after German unification. Using firm-product-level data with product quantities and prices, we analyze the role of product specialization and show that the prominent “extended work bench hypothesis” cannot explain these sustained productivity differences. Eastern firms specialize in simpler product varieties generating less consumer value and being manufactured with less or cheaper inputs. Yet, such specialization cannot explain the productivity gap because Eastern firms are physically less productive for given product prices. Hence, there is a genuine price-adjusted physical productivity disadvantage of Eastern compared to Western firms.JEL: D24, L11, L2, O47     

More bits – more bucks? Measuring the impact of broadband internet on firm performance

The paper provides empirical evidence for the causal impact of broadband Internet on firms’ labour productivity and realised process and product innovations. The analysis refers to the early phase of DSL expansion in Germany from 2001 to 2003, when roughly 60% of the German firms already used broadband Internet. Identification relies on instrumental variable estimation taking advantage of information on the availability of DSL broadband at the postal code level. The results show that broadband Internet has no impact on firms’ labour productivity, whereas it exhibits a positive and significant impact on their innovation activity.     

Unemployment and Right‐wing Extremist Crime*

It is frequently argued that unemployment plays a crucial role in the occurrence of right‐wing extremist crimes (RECs). We test this hypothesis empirically using data from Germany. We find that right‐wing criminal activities occur more frequently when unemployment is high. The substantial difference in the numbers of RECs occurring in the East and West German states can mostly be attributed to differences in unemployment. This finding reinforces the importance of unemployment as an explanatory factor for RECs, and it questions explanations based solely on the different socialization in former communist East Germany and the liberal West German states.     

Effectiveness of sequences of One-Euro-Jobs for welfare recipients in Germany

Empirical evidence reveals that German welfare recipients often participate in multiple active labour market programmes (ALMPs). However, evidence on the effectiveness of ALMPs exists mostly for single ALMP participations so far. This article evaluates the sequential participation in ALMPs for welfare recipients in Germany based on comprehensive administrative data to control for dynamic selection that arises in the evaluation of sequences. Using a dynamic causal model and an inflow sample of welfare recipients, the article analyses the effects of sequences of a public employment programme called One-Euro-Jobs on labour market outcomes. For female participants in One-Euro-Jobs in the first period, especially in West Germany, the results imply that participating in two consecutive One-Euro-Jobs compared with receiving only welfare benefits for two consecutive periods better facilitates integration into regular employment. Moreover, taking part in a One-Euro-Job directly after entry into welfare receipt is also more effective for participants in One-Euro-Jobs in the first period than taking part in a One-Euro-Job in a later period, especially for East German men (although not for West German women). However, I also find evidence of so-called programme careers and stepwise integration into regular employment.     

The east german disease revisited

This paper attempts to explain the development of the East German economy since the political, social, and economic union with West Germany in 1990. An earlier contribution [Greiner et al., 1994] showed the different effects that produced joint deindustrialization in East Germany as an analogy of the well-known Dutch Disease phenomenon. This paper examines recent East German time series of main economic variables since 1994. Though the business sector and the unions are ever more willing to correct errors of the past, fiscal transfers from West to East Germany continue to exert their pressure on the tradeables sector. Economic policy should encourage savings in East Germany and gradually change the structure of (declining) transfers to expenditures that generate new capacities.     

The intergenerational transmission of education and equality of educational opportunity in East and West Germany

Socialist societies often emphasized the abolition of traditional social classes. To achieve this objective, educational opportunities were at times ‘actively managed’ and allocated to children of less educated parents. What happened to these patterns after the demise of socialist rule in Eastern Europe? We study the development of educational mobility after the fall of the iron curtain in East Germany and compare the relevance of parental educational background for secondary schooling in East and West Germany. Based on the data from the German Mikrozensus we find that educational mobility is lower in East than in West Germany and that it has been falling in East Germany after unification. While the educational advantage of girls declined over time, having many siblings presents a more substantial disadvantage in East than in West Germany.     

INCOME INEQUALITY IN GERMANY DURING THE 1980s AND 1990s

The paper estimates a variety of inequality measures for three sub-samples of the German population using cross-sectional data on equivalent income from the German Socio-Economic Panel (GSOEP). The sub-populations under consideration are residents of West Germany including foreigners for the years 1984 to 1996, residents of East Germany for the years 1990 to 1996 and a comprehensive German population for the years 1990 to 1996. Bootstrap methods are applied to test whether changes in inequality are statistically significant. In order to account for panel attrition and over-sampling, sample weights are incorporated into the estimation procedure. The empirical results confirm the relative stability of the West German income distribution. While income inequality in West Germany has generally not altered in an economically relevant way over the period 1985 to 1996, inequality in East Germany has increased after reunification. Despite this increase, inequality remains substantially higher in the western part of the country. Convergence of eastern mean income to the western level generally overcompensated the rise in inequality in East Germany, so that the level of inequality in unified Germany is lower in 1996 than in 1990.     

Growth Effects of EU Membership: The Case of East Germany

The East German experience after unification in 1990 probably comes close to what might be called a controlled experiment for assessing the growth effects of EU membership. This article uses an open-economy neoclassical growth model as a measure of reference against which the actual performance of the East German economy can be evaluated. With no obvious differences in institutions and technology, and with physical capital accumulation in East Germany exceeding the West German rate, differences in human capital remain as the major reason for differences between the theoretical and the actual East German growth rate. Simulation results suggest that East Germany's stock of human capital per worker reaches only about one third of the West Germany level. The main lesson from the East German experience for other EU accession countries is that catching up may come to a halt below the EU average, even under pretty favorable institutional and financial conditions.     

Teenage pregnancies and births in Germany: patterns and developments

We study the development of teenage fertility in East and West Germany using data from the German Socioeconomic Panel and from the German Mikrozensus. Following the international literature we derive hypotheses on the patterns of teenage fertility and test whether they are relevant to the German case. We find that teenage fertility is associated with teenage age and education, with the income of the teenager’s family, with migration status, residence in East Germany and aggregate unemployment. Our evidence supports counter-cyclical teenage fertility.     

EFFECT OF PRIVATIZATION AND BROADER REFORMS ON LABOUR USE ADJUSTMENTS AND EFFICIENCY

State‐owned firms were said to have an excessive use of labour. The cost of job losses after privatization was debated but ignored due to perceived efficiency gains in the utilization of labour. We estimate longer time employment risk, labour use adjustment and the efficiency of labour utilization in the Pakistani cement industry. We conclude that firms have made significant adjustments in labour use and employment risks have indeed reduced. Our estimates however, show that long run labour use efficiency in the industry and in the privatized firms has not improved, but that, surprisingly, firms set‐up and operated privately have experienced a decrease in labour efficiency.     

How does entry regulation influence entry into self‐employment and occupational mobility?1

We analyse how an entry regulation that imposes a mandatory educational standard affects entry into self‐employment and occupational mobility. We exploit German reunification as a natural experiment and identify regulatory effects by comparing differences between regulated and unregulated occupations in East Germany with the corresponding differences in West Germany after reunification. Consistent with our expectations, we find that entry regulation reduces entry into self‐employment and occupational mobility after reunification more in regulated occupations in East Germany than in West Germany. Our findings are relevant for transition or emerging economies as well as for mature market economies requiring large structural changes after unforeseen economic shocks.
