Rising Wage Inequality in Germany

This paper investigates the evolution of wages and the recent tendency to rising wage inequality in Germany, based on the German Socio-Economic Panel (GSOEP) for 1984 to 2004. Between 1984 and 1994 the wage distribution was fairly stable. Wage inequality started to increase around 1994 in Germany for all workers and for prime age dependent male workers as well. Rising inequality is not the result of the recent rise in self-employment. In West Germany rising inequality occurred in the lower part of the wage distribution, in East Germany in the upper part of the wage distribution. While residual wage inequality accounted for two-thirds of rising wage inequality in West Germany, in East Germany price effects dominated. In West Germany the group of workers with low tenure experienced higher inequality.

Language usage, participation, employment and earnings: Evidence for foreigners in West Germany with multiple sources of selection

Language proficiency may not only affect the earnings of the individual, but the probability to participate in the labor market or becoming employed as well. It may also affect selection of people into economic sector and occupation. In this paper, the effects of language proficiency on earnings are analyzed for foreigners in Germany with joint consideration of up to four types of selection. The results show that language proficiency significantly increases participation and employment probability and affects occupational choice. When selection into economic sector and occupation is regarded, we do not find an impact of language ability on earnings thereby implying an indirect effect.

The Immigrant Wage Gap in Germany

Immigrants consist of foreigners and citizens with migration background. We analyze the wage gap between natives and these two groups in Germany. The estimates show a substantial gap for both groups with respect to natives. Discarding immigrants who completed education abroad reduces much of the immigrants’ wage gap. This implies educational attainment in Germany is an important component of economic integration and degrees obtained abroad are valued less.

The Immigrant-Native Wage Gap in Germany

Summary Immigrant-native wage differentials are observed in many countries, so in Germany. However, the available empirical literature for Germany defined the groups in consideration, immigrants and natives, by citizenship. This limits the explanatory power of the estimates since citizenship distinguishes foreigners and German nationals, but assigns naturalised immigrants (including the large group of ethnic Germans) to the latter group. Providing a more adequate definition based on the concept of origin we analyse the immigrant-native wage gap. Based on data from the German Socio-Economic Panel Study,we decompose the wage gap between native Germans, foreigners, and naturalised immigrants, and consider further subgroups in the analysis. In the literature, time of residence has been proven to be a relevant determinant of immigrants’ wages. For the natives, time of residence is perfectly collinear with age, and unequal sets of variables have to be considered.We therefore suggest an extension of the Oaxaca-Blinder decomposition technique. Our results show a substantial gap in earnings for all immigrants’ groups compared to natives. Discarding immigrants who completed education abroad reduces much of the immigrants’ wage gap. Hence, educational attainment in Germany is an important component of economic integration of immigrants, and degrees obtained abroad are valued less.

Noncognitive Skills, School Achievements and Educational Dropout

We analyse the determinants of dropout from secondary and vocational education in Germany using data from the Socio-Economic Panel from 2000 to 2007. In addition to the role of classical variables like family background and school achievements, we examine the effect of noncognitive skills. Both, better school grades and higher noncognitive skills reduce the risk to become an educational dropout. The influence of school achievements on the dropout probability tends to decrease and the influence of noncognitive skills tends to increase with age.

Wage Convergence and Inequality after Unification: (East) Germany in Transition

This paper investigates the wage convergence between East German workers and their West German counterparts after reunification. Our research is based on a comparison of three groups of workers defined as stayers, migrants and commuters to West Germany, who lived in East Germany in 1989, with groups of West German statistical twin workers, all taken from the Socio-Economic Panel (SOEP). According to our findings, wage convergence for stayers is roughly 75 percent and for commuters 85 percent. Wages of migrants to West Germany equal the ones of their West German statistical twins. We conclude that labor markets in East and West Germany are still characterized by wage differences but that the degree of inequality in both regions converged.

Decreasing wage mobility in Germany

Using data from the German Socio Economic Panel (SOEP) for the years 1984 to 2007, this paper analyses the amount, the development and the explanations of wage mobility, as well as volatility in West Germany, measured by ranks in the wage distribution. Individual wage mobility decreased between 1984/1987 and 2004/2007, while inequality increased steadily from the mid 1990s onwards. Mobility is highest in the middle section of the distribution. Better qualified persons, younger persons and employees of larger firms have higher chances of moving upwards. Wages are more volatile in the low-wage sector and for individuals moving downwards in the wage distribution.

Earnings Prospects for People With Migration Background in Germany

Less than half of the people with migration background living in Germany possess foreign citizenship. Hence, using citizenship to analyze economic issues of immigration may be problematic for two reasons. On the one hand, a quite substantial share of persons with migration background is neglected in the group of interest, and, on the other hand, the reference group (native Germans) may be contaminated by effects from naturalized immigrants. This paper utilizes a wider definition covering all persons with migration background to analyze the earnings prospects. To shed light on differences to the common use of citizenship, estimates are presented in comparison to foreigner and German citizens. The results show that persons with migration background have similar earnings prospects to foreigners. Moreover, earnings prospects for native Germans do not differ much from those of German citizenship. Therefore, using citizenship to approximate natives and non-natives when analyzing earnings issues seems to be reasonable. A second question of the paper is whether degrees obtained in Germany lead to better earnings prospects compared to degrees obtained abroad for persons with migration background. Independently of gender and skill level, the estimates affirm higher earnings to educational attainment in Germany.

Noncognitive Skills, Internet Use and Educational Dropout

Using data from the German Socio-Economic Panel for the years 2000 to 2006 we analyze the determinants and labor market effects of educational dropout. In addition to classical variables like family background and occupation, we examine noncognitive skills and Internet use. Noncognitive skills and Internet availability at home are negatively associated with the probability of becoming an educational dropout. The wage gap between dropouts and those with completed school and professional education vanishes for males once we control for additional characteristics such as occupations, professional Internet use and noncognitive skills. For females it is reduced to four percent.

Distributional Effects of the High School Degree in Germany

This paper investigates the impact of a high school degree on the wage distribution in the period from 1984 to 2004 in Germany. In that period the share of male workers with a high school degree increased from 16 to 25 percent. An econometric evaluation estimator is used to analyze quantile treatment effects for the whole population of male workers and for the subpopulation of workers with a high school degree. It turns out that the impact of a high school degree on the wage distribution for all workers is positive, whereas its impact on the wage distribution of the workers with a high school degree does statistically not differ from zero. This suggests that the selection of students into grammer schools might have been too restrictive. For more workers higher education would have raised their productivity and wages.
