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.

Wage Inequality, Reservation Wages and Labor Market Participation

This article presents an analysis of the variation of gender-specific labor-market participation rates across regions. A search-theoretical model with intertemporal optimization behavior of agents suggests that a higher regional wage level fosters participation, whereas higher unemployment discourages workers. The authors extend the standard model by introducing two measures of dispersion, one for the spread below and one for the spread above the median. It is shown that wage dispersion in the lower tail of the distribution decreases the value of search and leads to lower participation rates, although the reverse is true for wage dispersion in the upper tail. These implications of the model are tested using spatial econometrics.

Short-term training programs for immigrants: do effects differ from natives and why?

We evaluate the effects of different short-term training programs on the employment chances of immigrant and native welfare recipients in Germany. In particular, we investigate whether program effects differ between both groups and what might cause these potential differences. In a first step, we evaluate program effects separately for immigrants and natives using propensity score matching estimators. To explain potential differences in effects between the groups, we suggest and apply a decomposition method based on the matching procedure that allows identification of differences due to observable characteristics and differences related to an immigrant fixed effect in a second step.

Determinants of Internal Migration in Kazakhstan

In this paper we analyze the determinants of interregional migration in Kazakhstan using quarterly panel data on region to region migration in 2008–2010. To the best of our knowledge this is the first study on interregional population flows in Central Asia. We find that migration is determined by economic factors, first of all income: People are more likely to leave regions where incomes are low and more likely to move to regions with a higher income level. Furthermore, mobility is larger between more populated regions. Distance has a strong negative impact on migration, indicating high migration related costs and risks. Assuming that high migration costs are caused by poor infrastructure, investments in public and social infrastructure should facilitate regional income convergence in Kazakhstan and improve living standards in depressed regions.

Occupational and locational substitution: measuring the effect of occupational and regional mobility

The paper analyzes effects of occupational and regional mobility on the matching rate using the monthly panel disaggregated on regional and occupational level. The main contribution of the paper is measuring the effect of substitutability between vacancies for different occupations and vacancies in different regions on matchings. The estimates indicate higher regional mobility in West Germany but higher occupational mobility in East Germany. The results show that if occupations were perfect substitutes, the number of matches could increase by 5-9%. Perfect regional mobility could increase matchings by 5-15%. It is also shown that partial aggregation causes a downward bias in substitutability estimates.

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.

Short-term training programs for immigrants in the German welfare system: do effects differ from natives and why?

We evaluate the individual employment effects of four types of short-term training for immigrants and natives in the German welfare system and identify differences in the effects determined by unobservable factors. Based on comprehensive and unique administrative data, we apply propensity score matching in a dynamic setting to estimate the treatment effects and suggest the identification of unexplained effect differences between groups. The results show a mixed picture: two types of training increase the employment chances of immigrants, whereas the other two are rather ineffective. Effect differences between immigrants and natives predominantly result from socio-demographic composition.JEL codes: I38, C14, J61

Spatial Search and Commuting with Asymmetric Changes of the Wage Distribution

This paper contributes to job-search literature by analysing commuter behaviour in the presence of asymmetric changes in the wage distribution. Job search theory predicts that reservation wages increase with the mean and mean-preserving spread of the wage distribution. However, changing dispersion while holding the mean constant implies symmetric stretching or compression of the wage distribution in both tails, which is not likely to be the case when confronted with the real data. The presented model predicts that the commuter stream and the reservation wage increase with the median-preserving spread in the right tail and decrease with the median-preserving spread in the left tail in the destination. The empirical part, based on German commuter data, confirms the theory’s predictions.
