Abstract
The economic situation in German establishments improved even further in 2017. The development of wages, however, reflects this economic growth only partly. Compared to 1997, the wage differential between large and small establishments increased considerably – with substantially lower wages paid in East Germany in general. The wage differential of about 19 percent between East and West Germany can to some extent be explained in a multivariate analysis (Blinder-Oaxaca decomposition) showing that the main cause for the wage gap is the productivity gap between East German and West German establishments; other structural heterogeneities like sector composition, industrial relations and size structure seem not to contribute to an explanation of this gap. The overall positive economic development in Germany is associated with a further growth in total employment and with increased labor market dynamics, especially regarding employee turnover. Turnover rates, however, are very heterogeneous among sectors, ranging from 23 percent in the accommodation and food service sector and less than five percent in public administration. Also the demand for skilled personnel continued to grow. Yet for the first time, not even two thirds of the posted job vacancies could be filled in 2017. With over fifty percent, this non-occupancy quota is particularly high in the construction industry. Also small and very small establishments face serious recruitment problems. The structure of formal occupational skill requirements did not change very much over recent years, but the increasing use of digital technologies changes everyday job requirements and may lead to a rising workload for employees. Looking at the personnel structure in the German economy, a growing share of atypical employment becomes apparent, especially in form of part-time jobs. The proportion of marginal employment remains relatively stable and is comparatively high in sectors with less specific knowledge requirements and strong cyclical and/or seasonal fluctuations like is the case in accommodation and food service sector or personal services sector. Since 2010, the proportion of establishments authorized to provide in-company vocational training has declined constantly and now accounts for 53 percent of the establishments in Germany. About one half of these establishments do actually train apprentices. The share of vacant apprenticeships further increased in 2017 to about one quarter of all apprenticeships offered, in East Germany even to more than one third. As in recent years, the share of establishments supporting further training of their employees remained stable at about fifty percent and the proportion of employees participating in training is still about one third. In East Germany these figures prove to be slightly higher.

Abstract
Urban economies are composed of diverse activities, embodied in labor occupations, which depend on one another to produce goods and services. Yet little is known about how the nature and intensity of these interdependences change as cities increase in population size and economic complexity. Understanding the relationship between occupational interdependencies and the number of occupations defining an urban economy is relevant because interdependence within a networked system has implications for system resilience and for how easily can the structure of the network be modified. Here, we represent the interdependencies among occupations in a city as a non-spatial information network, where the strengths of interdependence between pairs of occupations determine the strengths of the links in the network. Using those quantified link strengths we calculate a single metric of interdependence–or connectedness–which is equivalent to the density of a city’s weighted occupational network. We then examine urban systems in six industrialized countries, analyzing how the density of urban occupational networks changes with network size, measured as the number of unique occupations present in an urban workforce. We find that in all six countries, density, or economic interdependence, increases superlinearly with the number of distinct occupations. Because connections among occupations represent flows of information, we provide evidence that connectivity scales superlinearly with network size in information networks.

Complex-task Biased Technological Change and the Labor Market
Colin Caines, Florian Hoffmann, Gueorgui Kambourov
Review of Economic Dynamics,
April
2017
Abstract
In this paper we study the relationship between task complexity and the occupational wage- and employment structure. Complex tasks are defined as those requiring higher-order skills, such as the ability to abstract, solve problems, make decisions, or communicate effectively. We measure the task complexity of an occupation by performing Principal Component Analysis on a broad set of occupational descriptors in the Occupational Information Network (O*NET) data. We establish four main empirical facts for the U.S. over the 1980–2005 time period that are robust to the inclusion of a detailed set of controls, subsamples, and levels of aggregation: (1) There is a positive relationship across occupations between task complexity and wages and wage growth; (2) Conditional on task complexity, routine-intensity of an occupation is not a significant predictor of wage growth and wage levels; (3) Labor has reallocated from less complex to more complex occupations over time; (4) Within groups of occupations with similar task complexity labor has reallocated to non-routine occupations over time. We then formulate a model of Complex-Task Biased Technological Change with heterogeneous skills and show analytically that it can rationalize these facts. We conclude that workers in non-routine occupations with low ability of solving complex tasks are not shielded from the labor market effects of automatization.

Strong Financial Literacy could Lead to More Self-employment
The probability that a person is self-employed also depends on how much financial literacy they have. A new study by the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association recently confirmed this correlation.

Agglomeration and FDI in East German Knowledge-intensive Business Services
Philipp Marek
Economia Politica,
No. 3,
2012
Abstract
The focus of this article is the empirical identification of factors influencing Foreign Direct Investment (FDI) in the knowledge-intensive business service (KIBS) sector on the regional level of «Raumordnungsregionen» in East Germany. The analysis focuses on the impact of regional agglomeration and technological capability on the location decision of foreign investors and West German MNEs. It shows that localisation, patent activity and the share of employees with an R&D occupation affect significantly the location decision of FDI. This result provides an explanation for the strong concentration of KIBS in urban areas in a post-transition economy.

Endogenous Selection of Comparison Groups, Human Capital Formation, and Tax Policy
Oded Stark, Walter Hyll, Y. Wang
Economica,
No. 313,
2012
Abstract
We consider a setting in which the acquisition of human capital entails a change of location in social space that causes individuals to revise their comparison groups. Skill levels are viewed as occupational groups. Moving up the skill ladder by acquiring additional human capital, in itself rewarding, leads to a shift in the individual’s inclination to compare himself with a different, and on average better-paid, comparison group, in itself penalizing. We shed new light on the dynamics of human capital formation, and suggest novel policy interventions to encourage human capital formation in the aggregate and reduce inter-group income inequality.

Seniorität, spezifisches Kapital und Beschäftigungsmobilität - Warum Ältere seltener wechseln

Abstract
The analysis focuses on the relationship of ageing and labour mobility. We answer the questions if i) mobility is wage driven, if ii) older workers are still able to generate wage increases by job switching and if iii) lacking wage incentives can explain the existing mobility gap of older workers. The empirical analysis is limited to labour mobility in terms of changing job or occupation. We estimate a multi equation model known as switching regression model with endogenous switching. The data stem from the IAB employment sample. We firstly show that expected wage increases encourage job switching. Secondly, we find evidence for lower expected wage increases due to job changes for older workers. Thirdly we find that the mobility gap of older workers is only partly attributable to reduced wage incentives of a job switch.

Children, Career, and Compromises: To what Extent does Offspring Affect Labour Force Participation and Career Opportunities of Women in Germany?
Alexander Kubis, Lutz Schneider, Marco Sunder
Wirtschaft im Wandel,
No. 11,
2009
Abstract
Germany faces a substantial challenge from demographic change in the forthcoming decades. While large cohorts reach retirement age, the working-age population shrinks. One option to curtail economic effects of this imbalance is to increase female labour force participation. The study uses data from the German Socio-Economic Panel (GSOEP) to analyze the impact of children on careers of women in East and West Germany, respectively in terms of participation and realized wages or occupational prestige. Results indicate strong regional differences, with East German mothers returning much faster to the labour market than their western peers. Participation rates – especially full-time employment – of the latter group remain permanently below levels of childless women. Careers of East German mothers are hampered by a higher risk of unemployment. The mother wage gap is relatively large among western mothers and remains so even after taking into account previous experience and unobserved heterogeneity. The study documents a negative and statistically significant relationship between children and occupational prestige only for West Germany. The observed career differences between mothers in both parts of the country may be rooted in a larger supply of institutionalized child-care arrangements in East Germany.

Abstract
On behalf of the Thuringian Ministry of Economics, Technology, and Labor, the Halle Institute for Economic Research (IWH) has conducted a survey of current labor market conditions in Thuringia. We forecast changes in labor demand within occupation groups in the period 2009-2015. According to our predictions, 80 000 additional workers are required both to replace older workers reaching retirement age and to accommodate industrial growth resulting from structural change. While the size of the working-age population will be large enough to meet this demand, there is a risk of occupational mismatch and lack of labor market integration of certain groups. In this context we devise policy recommendations. In addition, we present results of a survey of approximately 1 000 Thuringian companies. Interviews were conducted by IWH in the summer of 2008 and cover topics on previous and future staffing policy. The questionnaire focuses on companies’ strategies to meet their demand for skilled labor and their evaluation of potential measures in the fields of education, labor market, and economic policy.

Wirtschaft im Wandel,
No. 7,
2009
Abstract
We forecast the number of qualified workers required in the German federal state Thuringia until 2015 on the basis of the manpower requirement approach. Disaggregated by types of qualification, this method distinguishes between two sources of recruitment requirements: replacement demand for old workers and expansion demand to reflect structural changes of industry sectors and productivity growth. Both components are calculated from register data on employment covered by social security. Relative to current employment, recruitment requirements vary across occupations. A comparison of recruitment requirements for medium-skilled workers with the structure of vocational training reveals potential mismatch between demand and supply of medium-skilled labor in the near future if the composition of apprenticeship programs remains unchanged. The study closes with policy recommendations to prevent occupational mismatch.
