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.     

Does Firm Size make a Difference? Analysing the Effectiveness of R&D Subsidies in East Germany

We analyse the impact of public subsidies on private sector research and development (R&D) activity for a sample of East German firms. Using propensity score matching, our empirical results indicate that subsidized firms indeed show a higher level of R&D intensity (R&D expenditures relative to total turnover) and a higher probability for patent application compared with non‐subsidized firms. We find that, on average, the R&D intensity increases from 1.5% to 3.9%. The probability of patent application rises from 20% to 40%. These results closely match earlier empirical findings for East Germany. Given the fact that the East German innovation system is particularly driven by small‐ and medium‐sized enterprises (SMEs), we draw special attention to the effectiveness of R&D subsidies for this latter subgroup. Here, no specific empirical evidence is available so far. Our findings indicate that policy effectiveness also holds for private R&D activity of SMEs, with the highest increase in terms of R&D intensity being estimated for microbusinesses with up to ten employees.     

Additionality of public R&D grants in a transition economy

This paper examines the input and output additionality of public R&D subsidies in Western and Eastern Germany. We estimate the impact of public R&D grants on firms’ R&D and innovation input. Based on the results of this first step we compare the impact of publicly funded private R&D on innovation output with the output effect of R&D funded out of firms’ own pockets. We employ microeconometric evaluation methods using firm‐level data derived from the Mannheim Innovation Panel. Our results point towards a large degree of additionality in public R&D grants with regard to innovation input measured as R&D expenditures and innovation expenditures, as well as with regard to innovation output measured by patent applications. Input additionality has been more pronounced in Eastern Germany during the transition period than in Western Germany. However, R&D productivity is still larger for the established Western German innovation system than for Eastern Germany. Hence, a regional redistribution of public R&D subsidies might improve the overall innovation output of the German economy.     

Catching-up of East German Labour Productivity in the 1990s

We provide empirical evidence for exogenous and endogenous catching-up of East German labour productivity to West German levels. We argue that labour productivity in East Germany has caught up faster than has happened elsewhere. The sudden formation of the German Monetary Union was followed by large transfers to East Germany, migration of workers to West Germany, reorganization and privatization of East German firms. This has quickly led to a partial closing of the organizational, idea and object gaps that existed between East and West Germany. This paper analyses labour productivity in East and West Germany using both aggregate German data and unbalanced panel analysis of developments in East and West Germany. Factors affecting the organization of production, and especially privatization and 'foreign' firms, are found to be particularly important in this context.     

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.     

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 labour market effects of offshoring of small and medium-sized firms: micro-level evidence for Germany

Small and medium-sized enterprises (SMEs) are the economic powerhouse of many OECD countries (perhaps most prominently so in Germany). Yet, the labour market dynamics caused by the internationalization of their production activities are largely unexplored. We use survey-based micro-level data for Germany to explore the employment effects of offshoring of SMEs, relying on propensity score matching and difference-in-difference analysis. We find evidence for a downsizing effect in the immediate aftermath of offshoring whereas, initially, job creation is not spurred. In the medium run, we find evidence for a slowing down of employment dynamics of offshoring firms (that tend to belong to the better performing SMEs in Germany) relative to non-offshoring firms. Even though our results do not point to a net employment loss in the medium run, our evidence suggests that offshoring may lead to less jobs being created. This conclusion cannot be confirmed for large companies.     

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.     

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.

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.     

ECONOMIC RELATIONS BETWEEN WOMEN AND THEIR PARTNERS: AN EAST AND WEST GERMAN COMPARISON AFTER REUNIFICATION

abstract

This article compares women's and men's economic relations in East and West Germany following the 1990 reunification to exemplify the impact of varying opportunity structures on women's relative contribution to family income. West Germany's takeover set in motion a rapid transformation of East German institutions and employment structures. The analysis shows that women in West Germany became less dependent on their partners in the 1990s, largely because fewer women were housewives without earnings. In contrast, the contributions of women to the family economy in East Germany fell between 1990 and 1996. Afterwards, women in East Germany regained some of their economic power because of their partners' increasing difficulties sustaining employment. A multivariate analysis showed that the fact that women in West Germany were more likely to work less or not at all – especially if they were married or had children – accounted for much of the difference.     

Understanding co-operative innovative activity: evidence from four European countries

We investigate co-operative innovative activity in four major European countries, France, Germany, Spain and the UK, using internationally comparable firm-level data for manufacturing and service sectors. We examine the roles of knowledge flows, cost- and risk-sharing and public financial support in firms’ decisions to collaborate. Our results suggest that firms which place greater value on external information flows are more likely to co-operate with the research base than with other firms and that firms facing appropriability problems are more likely to co-operate with the research base and with upstream and downstream firms than with direct competitors. We find evidence for Spain to suggest that firms collaborate to overcome risks and financial constraints. We also find that receipt of public support is positively related to undertaking collaborative innovation. In line with the focus of policy, this relationship is strongest for co-operation with the research base.     

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.     

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.     

R&D INVESTMENT, CREDIT RATIONING AND SAMPLE SELECTION

We study whether R&D‐intensive firms are liquidity constrained, by modelling their antecedent decision to apply for credit. This sample selection issue is relevant when studying a borrower–lender relationship, as the same factors can influence the decisions of both parties. We find firms with no or low R&D intensity to be less likely to request extra funds. When they do, we observe a higher probability of being denied credit. Such a relationship is not supported by evidence from the R&D‐intensive firms. Thus, our findings lend support to the notion of credit constraints being severe only for a sub‐sample of innovative firms. Furthermore, the results suggest that the way in which the R&D activity is organized may differentially affect a firm's probability of being credit constrained.

Temporary overpessimism: Job loss expectations following a large negative employment shock

Job loss expectations were widespread amongst workers in East Germany following reunification with West Germany. Though experiencing a large negative employment shock, East German workers were nevertheless overpessimistic immediately after reunification with respect to their job loss risk. Over time, job loss expectations fell and converged to West German levels, which was driven by a stabilizing economic environment and by an adaptation of the interpretation of economic signals with workers learning to distinguish individual risk from firm-level risk. In fact, conditional on actual job loss risk, East German workers quickly caught up to West Germans regarding the share of correctly predicted job losses.
