Trade and unions: Can exporters benefit from collective bargaining?
20 October 2014
Unions are often stigmatized as being a source of inefficiency due to higher collective bargaining outcomes. This is in stark contrast with the descriptive evidence presented in this paper. Larger firms choose to export and are also more likely to adopt collective bargaining. We rationalize those stylized facts using a partial equilibrium model that allows us to evaluate firms' value functions under individual or collective bargaining. Exporting further decreases average production costs for large firms in the collective bargaining regime, allowing them to benefit from additional external economies of scale due to lower bargaining costs. Our findings suggest that the positive correlation between export status and collective bargaining can be explained through size.

The implementation of the German Classification of Occupations 2010 in the IAB Job Vacancy Survey
30 September 2014
The IAB-Job Vacancy Survey (IAB-JVS) is the only establishment survey in Germany which contains information about vacancies and new hires on an occupational level. When the new German Classification of Occupations 2010 was introduced, it became necessary to integrate it into the IAB-JVS. This report outlines the implementation of the new classification into the IAB-JVS questionnaire. It was conducted simultaneously with the renewal of the international classification, from ISCO-88 to ISCO-08.

Employment and earnings effects of awarding training vouchers in Germany
17 September 2014
In 2003, Germany moved from a system in which participants in training programs for the unemployed are assigned by caseworkers to an allocation system using vouchers. Based on the rich administrative data for all vouchers and on actual program participation, we provide inverse probability weighting and ordinary least squares estimates of the employment and earnings effects of a voucher award.

Determinants of labor shortage - with particular focus on the German environmental sector
29 August 2014
Despite the ongoing discussion on labor shortage in the German economy there is still a lack of empirical analyses of this problem based on adequate econometric methods. The paper explores the determinants of labor shortage in the environmental sector supplying products and services that help to reduce environmental impacts and energy use. Labor shortages occur when the price adjustment mechanism is too slow to balance labor demand and supply. The empirical analysis of labor shortage uses recent data of the establishment panel of the Institute for Employment Research in Nuremberg. A descriptive analysis shows that the environmental sector seems to be over-proportionally affected by labor shortage.

On GDP-employment decoupling in Germany
29 August 2014
This paper investigates the time-varying relationship between German output and employment growth, in particular their decoupling in recent years. We estimate a correlated unobserved components model that allows for both persistent and cyclical time variation in the employment impact of GDP as well as an autonomous employment component capturing other factors than real output. As one result, we measure a permanent decline in Verdoorn's coefficient as well as pronounced effects of the autonomous employment component in the recent years. The development of the estimated impact parameters is shown to crucially depend on structural change, but also on labour availability and business expectations.

Labour market effects of retraining for the unemployed
27 August 2014
We analyse the impact of retraining for the unemployed on future labour market success, and estimate effects separately for different target occupations. We use German registry data and apply statistical matching methods. The results show that on average, after a period with strong lock-in effects, retraining increases the employment probability of women by more than 20 percentage points. Effects for male participants are somewhat weaker. Although we find differences in the effectiveness of retraining by target occupations, these differences cannot completely explain the observed gender differences. Healthcare occupations, which are the most important target occupations especially of female participants, are among those with the strongest effects.

Firm performance and trade with low-income countries
26 August 2014
Do firms in developing countries shift trade towards developed economies as a result of high economic growth? The matched customs-manufacturing firm data used in this study confront this hypothesized link with empirical evidence. Our analysis reveals a rising low-income country trade share around and after China's accession to the World Trade Organization. Based on this stylized fact, we analyze the link between firm characteristics and trade with low-income countries.

Job polarization on local labor markets
22 August 2014
The labor markets of most industrialized countries are polarized. This means that employment has grown in jobs at the upper and lower tails of the wage distribution, while employment in the middle part of the distribution has stagnated or declined. However, there exists no measure that allows a quantitative comparison across different labor markets as yet. The author propose a straightforward way to measure the actual magnitude of job polarization. To demonstrate its application, he use this measure to compare polarization across German local labor markets. Job polarization almost exclusively occurs in urban areas where the hypothesis of routine biased technological change is most likely to prevail.

Industry space and skill-relatedness of economic activities
21 August 2014
The resilience and growth prospects of a region depend crucially on the extent to which industry-specific human capital can be redeployed across the industries of a regional economy. To this end, the authors present a toolbox to analyse a region’s industrial structure, development prospects and economic resilience. With the help of this toolbox human capital similarities, or skill-relatedness, among industries are highlighted. The core of these analyses is the so-called industry space, a network that connects industries with similar human capital requirements. For the time period 1999 to 2008, a regional comparative analysis of three eastern German automobile regions, namely south-west Saxony (SWS), Eisenach region (EIS) and Leipzig region (LEI), is conducted.
Techniques for asking sensitive questions in labor market surveys
29 July 2014
Standard surveying techniques are usually not suited to collect valid information on the prevalence of undeclared work or receipt of basic income support. Respondents often misreport their behavior and adjust their answer in accordance with the social norm. In the social sciences alternative strategies have been developed, particularly targeted to increase respondent anonymity in the interview situation and thus reduce misreporting on sensitive topics. Antje Kirchner investigates whether these special techniques lead to higher reports of undeclared work and receipt of basic income support. Furthermore, this work presents the Item Sum Technique, a novel questioning technique that shows more promising results compared to direct questioning.
Labour hoarding in Germany
02 July 2014
During the crisis (2008-09) Germany experienced a huge decrease in GDP. Employment, however, remained surprisingly stable. A whole strand of literature has aimed at quantifying the contribution of short-time work to the German labour market miracle. In the course of this literature we estimate the treatment effect of short-time work on employment at establishment level using a dynamic propensity score matching approach. The analysis is based on data from the IAB Establishment Panel combined with administrative data on short-time work establishments from the Federal Employment Agency. Our results do not indicate any treatment effect of short-time work on employment.

Forecasting with a mismatch-enhanced labor market matching function
27 June 2014
This paper investigates the role of mismatch between job seekers and job openings for the forecasting performance of a labor market matching function. In theory, higher mismatch lowers matching efficiency which increases the risk that the vacancies cannot be filled within the usual period of time. We investigate whether and to what extent forecasts of German job findings can be improved by a mismatch-enhanced labor market matching function. For this purpose, we construct so-called mismatch indicators that reflect regional, occupational and qualification-related mismatch on a monthly basis. In pseudo out-of-sample tests that account for the nested model environment, we find that forecasting models enhanced by the mismatch indicator significantly outperform their benchmark counterparts for all forecast horizons ranging between one month and a year. This is especially pronounced in the aftermath of the Great Recession where a low level of mismatch improved the possibility of unemployed to find a job again.

Patterns of resilience during socioeconomic crises among households in Europe (RESCuE)
16 May 2014
In analogy with medical and psychological findings, some parts of the vulnerable population, although experiencing the same living conditions as others, are developing resilience, which in our context means that they perform social, economic and cultural practices and habits which protect them from suffer and harm and support sustainable patterns of coping and adaption. This resilience to socioeconomic crises at household levels is the focus of the project.
Economic failure and the role of plant age and size
12 May 2014
This paper introduces a large-scale administrative panel data set on corporate bankruptcy in Germany that allows for an econometric analysis of involuntary exits where previous studies mixed voluntary and involuntary exits. Approximately 83 percent of all bankruptcies occur in plants with no more than 10 employees, and 61 percent of all bankrupt plants are not older than 5 years. The descriptive statistics and regression analysis indicate substantial negative age dependence with respect to bankruptcy risk but confirm negative size dependence for mature plants, only. Our results corroborate hypotheses stressing increasing capabilities and positional advantage, both predicting negative age dependence with respect to bankruptcy risk due to productivity improvements. The results are not consistent with the theories explaining age dependence via imprinting or structural inertia.

The hidden winners of renewable energy promotion
07 May 2014
In light of Germany´s transition approaches towards a sustainable energy system this paper examines differences of employment structure and wage differentials between renewable energy establishments and their sector peers. To do so, we have developed a novel data set by linking company-level information from the German Renewable Energy Federation with establishment-level data of the IAB Establishment History Panel. According to our descriptive evidence, there are significant differences in wages and in several other characteristics. Looking at the top-four renewable energy sectors, our estimates show that human capital and other establishment- level characteristics mostly explain the wage differential among manufacturers and energy providers. However, we find a persistent 'renewable energy wage premium' of more than ten percent in the construction installation activities and the architectural and engineering services. We interpret this premium as a positive indirect effect of the promotion of renewable energies for the benefit of employees in renewable energy establishments within these two sectors.

Efficiency in public input provision in two asymmetric jurisdictions with imperfect labour markets
22 April 2014
This paper examines efficiency in public input provision in two large jurisdictions with imperfect labour markets. It analyses how equilibrium capital tax rates and public input provision levels differ between asymmetric jurisdictions that can strategically influence the interest rate on the common capital market in an international tax competition setting. In contrast to the scenario assuming competitive labour markets, the non-cooperative equilibrium is inefficient also when governments have capital and head taxes at disposal. As a source of both the distortion in the capital allocation between jurisdictions and the inefficiency in public input provision, which can be determined in at least one of the jurisdictions, we identify the governments' incentives to decrease unemployment, and a pecuniary externality [De- Pater, J., Myers, G., 1994. Strategic capital tax competition: a pecuniary externality and a corrective device. Journal of Urban Economics 36, 66-78.] in both jurisdictions. Efficiency in public input provision can be restored, however, if the set of fiscal instruments available for regional policy makers is extended by a labour tax.

Sorting within and across establishments
17 April 2014
Using new and unique linked employer-employee data from Germany, I examine the extent to which immigrants sort into worse-paying establishments and worse job positions within establishments. The results demonstrate that recent immigrants are particularly likely to work at low-paying workplaces. Similarly, when examining job positions within establishments, I find that immigrants are employed in lower hierarchical positions. Both the non-random sorting across establishments and the hierarchical sorting within establishments explain much of the immigrant-native wage differential. Policy measures designed to address the wage differential should therefore address immigrants' access to well-paying workplaces and job positions.

Ulrich Walwei, deputy director of the IAB, describes Germany’s transformation and discusses the remaining weaknesses of the German labour market.
On the efficiency properties of the Roy‘s model under asymmetric information
24 March 2014
We consider Roy's economies with perfectly competitive labor markets and asymmetric information. Firms choose their investments in physical capital before observing the characteristics of the labor markets they will face. We provide conditions under which equilibrium allocations are constrained Pareto efficient, i.e., such that it is impossible to improve upon the equilibrium allocation by changing agents' investments and letting the other endogenous variables adjust to restore market clearing. We also provide a robust example of a class of economies where these conditions fail and where equilibria are characterized by overinvestments in high skills. Finally, we discuss some implications of our main results for the optimal taxation literature.

Success and failure in the operational recruitment process
13 March 2014
Following microeconomic theory, every vacancy should be filled by appropriate manpower after a certain time. However, from an empirical point of view it is evident that vacancies remain unfilled as establishments cancel their search for a suitable applicant. The German Job Vacancy Survey (JVS) is a representative survey of job offers for the entire German economy and provides information about the search and matching processes for both the establishments' most recent hires and for failures in the recruitment processes. The analysis is based on a binary explanatory variable, resulting from the interaction of individual successful and unsuccessful search processes (cancellation probability). Our results show that with increasing recruitment duration, the number of search cancellations becomes more likely. Moreover, the results indicate that the probability of a search cancellation is strongly linked to the characteristics that an applicant must provide and to the way the search is organised.

Active labour market programmes for women with a partner
04 March 2014
A major unemployment and welfare benefit reform took place in Germany in 2005. One objective of this reform was to more strongly encourage an adult worker model of the family, with an emphasis on activating the formerly inactive. The authors' hypothesis is, however, that assignments to activation programmes, such as training or workfare, will in practice still tend to replicate patterns for the division of labour in the household that couples have become accustomed to.

Revisiting the matching function
28 February 2014
Many labor market models use both idiosyncratic productivity and a vacancy free entry condition. This paper shows that these two features combined generate an equilibrium comovement between matches on the one hand and unemployment and vacancies on the other hand, which is observationally equivalent to a constant returns Cobb-Douglas function commonly used to model match formation. The authors use German administrative labor market data to show that the matching function correlation solely based on idiosyncratic productivity and free entry is very close to the empirical matching function.

Interacting product and labor market regulation and the impact of immigration on native wages
26 February 2014
Does interacting product and labor market regulation alter the impact of immigration on wages of competing native workers? Focusing on the large, sudden and unanticipated wave of migration from East to West Germany after German reunification and allowing for endogenous immigration, we compare native wage reactions across different segments of the West German labor market: one segment without product and labor market regulation, to which standard immigration models best apply, one segment in which product and labor market regulation interact, and one segment covering intermediate groups of workers. We find that the wages of competing native West Germans respond negatively to the large influx of similar East German workers in the segment with almost free firm entry into product markets and weak worker influence on the decision-making of firms. Competing native workers are insulated from such pressure if firm entry regulation interacts with labor market institutions, implying a strong influence of workers on the decision-making of profit-making firms.

Regional determinants of German FDI in the Czech Republic
25 February 2014
The attractiveness for the location of multinational firms is seen as a crucial issue for the development and prosperity of regions. This article focuses on a two-country relationship and deals with the regional distribution of German multinational firms and their affiliates in the Czech Republic. A new dataset established by the IAB covers information on the basic population of cross-border foreign direct investment (FDI) projects, thereby exceeding the number of observations in previously used databases by far. On the basis of 3,894 FDI projects the regional determinants of German cross-border investments in the Czech Republic are analysed for both the home and the host country. Alternative specifications of the gravity model are used in order to investigate the regional distribution of common investment projects that are calculated as a combination of a headquarters in a German spatial planning region and an affiliate in a Czech NUTS 3 region. Concerning the explanatory variables a distinction is made between three groups of factors: first, market size and agglomeration features of the regions; second, attributes representing the distance between the headquarters in Germany and the affiliates in the Czech Republic; and third, regional labour market characteristics. While the findings are generally in line with theoretical expectations, differences emerge between manufacturing FDI and services FDI.

Beat the heap - an imputation strategy for valid inferences from rounded income data
03 February 2014
Questions on income in surveys are prone to two sources of errors that can cause bias if not addressed adequately at the analysis stage. On the one hand, income is considered sensitive information and response rates on income questions generally tend to be lower than response rates for other non-sensitive questions. On the other hand respondents usually don’t remember their exact income and thus tend to provide a rounded estimate. The negative effects of item nonresponse are well studied and most statistical agencies have developed sophisticated imputation methods to correct for this potential source of bias. However, to our knowledge the effects of rounding are hardly ever considered in practice, despite the fact that several studies have found strong evidence that most of the respondents round their reported income values.

Your very private job agency
13 January 2014
This paper analyzes job referral effects that are based on residential location. We use georeferenced record data for the entire working population (liable to social security) and the corresponding establishments in the Rhine-Ruhr metropolitan area, which is Germany's largest (and EU's second largest) metropolitan area. We estimate the propensity of two persons to work at the same place when residing in the same neighborhood (reported with an accuracy of 500m×500m grid cells), and compare the effect to people living in adjacent neighborhoods. We find a significant increase in the probability of working together when living in the same neighborhood, which is stable across various specifications. We differentiate these referral effects for socioeconomic groups and find especially strong effects for migrant groups from former guestworker countries and new EU countries. Further, we are able to investigate a number of issues in order to deepen the insight on actual job referrals: distinguishing between the effects on working in the same neighborhood and working in the same establishment - probably the more accurate measure for job referrals - shows that the latter yield overall smaller effects. Further, we find that clusters in employment although having a significant positive effect play only a minor role for the magnitude of the referral effect. When we exclude short distance commuters, we find the same probabilities of working together, which reinforces our interpretation of this probability as a network effect.

On government-subsidized training programs for older workers
19 December 2013
We analyze the impact of the GermanWeGebAU programs, which are government-subsidized training measures for employed workers over 45 years old. We apply a dynamic matching approach similar to Crépon et al. (2009) and exploit novel information contained in rich German registry data. We focus on the effects on survival probability in original employment and estimate the effects separately by gender, age, job status, and program duration. We find that WeGebAU training improves the probability of remaining in paid employment by 1.0 to 2.5 percentage points in the two-year period following treatment. The effect is more pronounced for part-time workers and longer-duration program participants. Our analysis suggests that postponed labor market withdrawal is the main driver of the positive effects and that there is selection into treatment at the firm level.

Constructing a new leading indicator for unemployment from a survey among German employment agencies
28 October 2013
The paper investigates the predictive power of a new survey implemented by the Federal Employment Agency (FEA) for forecasting German unemployment in the short run. Every month, the CEOs of the FEA's regional agencies are asked about their expectations of future labor market developments. We generate an aggregate unemployment leading indicator that exploits serial correlation in response behavior through identifying and adjusting temporarily unreliable predictions. We use out-of-sample tests suitable in nested model environments to compare forecasting performance of models including the new indicator to that of purely autoregressive benchmarks. For all investigated forecast horizons (1, 2, 3 and 6 months), test results show that models enhanced by the new leading indicator significantly outperform their benchmark counterparts. To compare our indicator to potential competitors we employ the model confidence set. Results reveal that models including the new indicator perform very well.

The effectiveness of sequences of One-Euro-Jobs
10 October 2013
Many studies have analysed the effectiveness of single active labour market programmes (ALMPs) for welfare recipients in different countries. As empirical evidence reveals that welfare recipients in Germany often participate in multiple programmes, I evaluate the sequential participation of unemployment benefit II (UB-II)-recipients in ALMPs in Germany. My study uses comprehensive, administrative data to control for dynamic selection that arises in the evaluation of sequences. Using a dynamic matching approach and an inflow sample of UB-II-recipients, I analyse the effects of sequences of One-Euro-Jobs and/or UB II-receipt on labour market outcomes.

Wage posting or wage bargaining?
20 September 2013
Using a representative establishment dataset, this paper is the first to analyze the incidence of wage posting and wage bargaining in the matching process from the employer’s side. We show that both modes of wage determination coexist in the German labor market, with about two-thirds of hirings being characterized by wage posting. Wage posting dominates in the public sector, in larger firms, in firms covered by collective agreements, and in part-time and fixed-term contracts. Jobseekers who are unemployed, out of the labor force or just finished their apprenticeship are also less likely to get a chance of negotiating. Wage bargaining
is more likely for more-educated applicants and in jobs with special requirements as well as in tight regional labor markets.

Labour market forecasting: Is disaggregation useful?
18 September 2013
Using the example of short-term forecasts for German employment figures, the article at hand examines the question whether the use of disaggregated information increases the forecast accuracy of the aggregate. For this purpose, the out-ofsample forecasts for the aggregated employment forecast are compared to and contrasted with forecasts based on a vector-autoregressive model, which includes not only the aggregate but also the numbers of gainfully employed people at the industry level. The Clark/West test is used in the model comparison. It becomes evident that disaggregation significantly improves the employment forecast. Moreover, fluctuation-window tests help identify the phases during which disaggregation increases forecast accuracy to the strongest extent.

This paper analyzes the impact of the skill composition of migration flows on the host country’s labor market in a specific factors two-sector model with heterogeneous labor (low-, medium-, and highly-skilled) and price- and wage-setting behavior. The low- and medium-skilled labor markets are characterized by frictions due to wage bargaining. Moreover, we assume skill downgrading of unemployed medium-skilled workers into low-skilled labor supply. Endogenous benefits create an interdependency between the two bargaining processes.

Skilled labour requirements in firms
30 July 2013
Establishments in the manufacturing sector that export goods usually pay their employees considerably more than those that do not. IAB researchers have followed up the reasons for this in the current issue of the IAB-Forum, entitled "Vantage point. The establishment-level perspective of the labour market". The initially surprising findings show that the establishment-level perspective opens up important and sometimes unexpected insights into the labour market. To make this view of the labour market useful for research as well, the IAB Establishment Panel was launched in 1993. The results of the annual survey are of great advantage to in-house practice, political decision-making and also to the operative activities of the Federal Employment Agency – for instance when solutions are being sought on how to deal with shortages of skilled workers, aging workforces, the compatibility of family and career, framework conditions for employee participation, or the in-house use of integration subsidies.

The re-entry of mothers in Germany into employment after family-related interruptions
09 July 2013
It is still difficult for mothers in Germany to reconcile family life with employment. This becomes particularly apparent when mothers attempt to re-enter the labour market. Partly this varies very strongly according to level of education; partly legal regulations on parental leave play a decisive role. In addition, women in the Western part of Germany interrupt their employment for a longer time than women from the Eastern part of Germany - even twenty years after reunification. In the meantime, this appears to be more a result of different institutional regulations rather than differing socialisation. Finally, the re-entry of mothers into the labour market after interrupting their employment to have and look after children also seems to depend on the characteristics of the jobs offered. Here it becomes apparent that, along with pay, non-monetary characteristics also play an important role - especially those affecting one's personal time budget.
The ReLOC project

Economic integration typically goes along with a disintegration of production through outsourcing and offshoring. The consequences of foreign direct investments (FDI) especially for the labour market are an issue of ongoing debate. The countries of origin fear job losses. However, a range of models and studies show that the productivity gains lead to job growth at the domestic plants.
The method report presents the questions which arose through a cross-border company survey and the solutions found. The process of the implementation is described, focussing on the creation of the database as well as on the questionnaire development.

Trade and qualifikation
06 June 2013
Foreign markets determine success and failure of those industries that have become reliant on foreign demand, impair the demand for employment and invoke changes in occupational fields and qualification requirements. This paper aims to disclose the direct and indirect influence of major trading partners on Germany's production, employment, and qualification needs. It projects the effects by using the dynamic macro-econometric input-output model INFORGE. Industrialised economies are the most important determinants for employment in the manufacturing industries. Business-related services are highly indirectly affected. The growth impact of industrialised nations is declining while BRICS nations are gaining momentum. A shift towards higher qualification needs can be observed.

The autors answer this question with German administrative matched employer-employee data that track more than 800,000 individuals over 24 years. Using a censored quantile instrumental variable estimator and instrumenting early-career unemployment with local labor market conditions at labor market entry and firm-specific labor demand shocks, they find significant and longlasting scarring effects. At the median, an additional day of unemployment during the first eight years on the labor market increases unemployment in the following 16 years by 0.96 days. Effects are even stronger in the right tail of the unemployment distribution. Likely due to unobserved heterogeneity in returns to search, they are also understated by non-IV estimates.

Subsidies for substitutes?
22 May 2013
This paper estimates substitution effects of the German active labour market programme "JobPerspektive", a wage subsidy for hard-to-place welfare recipients. Results provide little evidence for widespread substitution of regular workers due to receiving this particular subsidy; in fact, regular employment is somewhat increased in West Germany as a result of subsidization.

Does it matter where you work?
15 May 2013
Using rich German linked employer-employee data and endogenous switching regression models, this paper shows that large firms and firms with a high export share or a low proportion of fixed-term workers provide higher wage growth for low-wage workers. While having many low-paid co-workers dampens the wage growth of both low-wage workers and higher-wage workers, there are also employers who provide higher wage growth only for higher-wage workers.

Effects of participating in skill training and workfare on employment entries for lone mothers receiving means-tested benefits in Germany
18 April 2013
This paper investigates employment effects of further vocational training, short classroom training, as well as One-Euro-Jobs for lone mothers receiving Unemployment Benefit II (UB II) in Germany. Lone mothers receiving UB II participate in these active labor market programs at very high rates. As soon as their youngest child is aged three or above, their program entry rates are as high as for childless singles. This paper examines whether lone mothers can actually profit from partici-pating in these programs, given low levels of childcare provision.

Motivated underreporting in screening interviews
08 April 2013
Most surveys begin with questions designed to determine whether the sample household includes any members of the survey's target population. However, the screening questions can miss eligible household members. The underreporting of eligible household members may reflect interviewer motivation, respondent motivation, or some combination of the two. The authors did an experiment to test several hypotheses about this phenomenon, which they call motivated underreporting.
Evaluating the labor-market effects of compulsory military service

The authors identify the causal effect of compulsory military service on conscripts' subsequent labor-market outcomes by exploiting the regression-discontinuity design of the military draft in Germany during the 1950s.
(When) Is job-finding via personal contacts a meaningful concept for social network analysis?
03 April 2013
Chua (2011) argues that in a meritocratic context, institutions restrict the usefulness of social networks in exerting influence on job seekers' earnings. Regressing job-finding via personal contacts on earnings, he finds negative effects of influence via personal contacts, especially for the well-educated and individuals working in the state sector.
Feature: Flexible forms of employment
03 April 2013
In recent decades, economic policy makers across Europe have sought to increase labour market flexibility by promoting the use of temporary employment. The articles in this Feature provide new results on how fixed-term and agency work contracts affect firm productivity and how the segments of two-tier labour markets interact.
Patterns of unemployment dynamics in Germany
02 April 2013
This paper studies the patterns of unemployment dynamics in Germany. To provide a deeper insight into the margins of unemployment adjustment, we employ a structural VAR model and identify the effects of a technology shock as well as two policy shocks. The authors find that the worker reallocation process varies substantially with the identified shocks.

Does downward nominal wage rigidity dampen wage increases?
25 March 2013
Focusing on the compression of wage cuts, many empirical studies find a high degree of downward nominal wage rigidity (DNWR). The authors analyze whether a compression of wage increases occurs when DNWR is binding by applying Unconditional Quantile Regression and Seemingly Unrelated Regression to a dataset comprising more than 169 million wage changes.
The effects of extended unemployment insurance over the business cycle
25 March 2013
One goal of extending the duration of unemployment insurance (UI) in recessions is to increase UI coverage in the face of longer unemployment spells. Although it is a common concern that such extensions may themselves raise nonemployment durations, it is not known how recessions would affect the magnitude of this moral hazard. To obtain causal estimates of the differential effects of UI in booms and recessions, this article exploits the fact that in Germany, potential UI benefit duration is a function of exact age which is itself invariant over the business cycle.

A new look at the discouragement and the added worker hypotheses
13 February 2013
Using German data this study applies an unobserved-components approach to disentangle the unemployment rate into a (stochastic) trend and a cyclical part and to estimate the influence of these components on labor participation. The persistent trend component of unemployment, which triggers permanent reactions of the workers, is likely connected to a structural discouragement effect. The cyclical component, which reflects more fluctuant changes, can be linked to a shorter-term added worker effect. By splitting up the participation effect of changes in the unemployment rate our analysis differs profoundly from previous studies that present the net of both or only a single effect. For the total working population both a discouragement and an added worker effect were identified. In detailed analyses we find that the former was relevant for older workers, whereas the latter especially concerns prime aged and younger females. As many OECD countries are facing an ageing population as well as rising importance of women in the labor market, these age- and gender-specific results might be of particular interest.

More competition for bright minds
17 December 2012
Qualified professionals are the fuel of a knowledge-intensive economy, the fuel that gives Germany the necessary thrust in international competition. But more than a few people are worried that qualified professionals could soon become scarce. That is why the current issue of the IAB-Forum has chosen to examine this much discussed topic of "ensuring the availability of qualified professionals" (Fachkräftesicherung) from various different angles. The IAB-Forum is published only in German. Some of the selected articles of this edition have been translated into English.

Decomposing Beveridge curve dynamics by correlated unobserved components
10 December 2012
Between 1979 and 2009, the German labour market moved along a Beveridge curve with changing slope that usually shifted outwards but once inwards. We em-ploy an unobserved components model to simultaneously disentangle permanent and transitory components of matching efficiency and separation rate (shifting pa-rameters) as well as unemployment and vacancies. Cointegration and identification are especially addressed. We find a steady overlay of structural and transitory shocks for both shifts of and movements along the curve. Thereby, the separation rate is more important than matching efficiency and the two are negatively corre-lated. Labour market tightness is mostly driven by stochastic trends, which leads to permanent rotations of the job creation curve, i. e. movements along the Beveridge curve.

Job matching across occupational labour markets
03 December 2012
This paper refers to an analysis of matching processes in occupational labour markets in terms of classes of jobs that share extensive commonalities in their required qualifications and tasks. To date, all studies in this field have been based on the assumption of separate occupational labour markets. This assumption suggests that job search and matching processes only transpire within distinct occupational labour markets and that no occupational changes occur. I present theoretical and empirical arguments that undermine the validity of this assumption. Moreover, I construct an "occupational" topology based on information about the ways in which occupational groups may be seen as alternatives in searches for jobs or workers respectively. I then use pooled ordinary least squares, fixed effects, and pooled mean-group models that consider cross-sectional dependency lags for regressors to test the hypothesis that job search and matching occur across occupational labour markets. In particular, I find significant and positive matching elasticities with respect to the averaged numbers of unemployed workers and vacancies in similar occupational groups; these results clearly support my hypothesis. Furthermore, there are indications that returns to scale that are derived from the results of the pooled mean-group model are constant. The findings of this study strongly suggest the use of an augmented matching function that considers job and worker searches across occupational labour markets.

The formation of experts' expectations on labour markets
29 October 2012
Expectations regarding the economic development might be correlated due to various reasons: because individuals use the same public information and similar evaluation methods, and because of social learning or herding amongst peers. We analyse to what extent expectations are driven by herd behaviour, and if it contributes to make expectations more realistic. In a novel survey the CEOs of the local departments of the German Federal Employment Agency report their expectations on unemployment in the short run. In this data we can discriminate between close and less-close peers to overcome the reflection problem and to quantitatively assess answers regarding the initial questions. We find strong evidence for herding in expectation formation. The size of effect is robust across various specifications and remains even when controlling for forecasts from experts external to the survey. The social multiplier approximately doubles the effect of information (signals) included in the model. Compared to counterfactual expectations without herding constructed from the estimates, herding seems to improve the accuracy of the expectations.

Skill-biased labor market reforms and international competitiveness
10 October 2012
This paper proposes a multi-industry trade model with integrated capital and goods markets. Labor market imperfections in line with Mortensen and Pissarides (1994) give rise to unemployment and a channel for the government to influence markets through institutional changes. Labor market interventions feedback into the product market through changes in a country's competitiveness. Moreover, the distinction between high- and low-skill workers facilitates the analysis of skill-biased institutional changes that have stronger impact on certain skill groups. The comparative static exercise in this paper shows that high-skilled benefit from low-skill biased labor market reforms through higher wages. Lower labor costs reduce unemployment of the low-skilled and increases the reforming country's competitiveness. One-sided labor market interventions have feedback effects through adjustments at the extensive margin, which affect all workers at home and abroad irrespective of their level of skill. Governments in the non-reforming countries may react to this loss in competitiveness by initiating cooperative labor market reforms instead.

Human capital mobility and convergence
24 September 2012
Since the fall of the iron curtain in 1989, the migration deficit of the Eastern part of Germany has accumulated to 1.8 million people, which is over 10 percent of its initial population. Depending on their human capital endowment, these migrants might either - in the case of low-skilled migration - accelerate or - in high-skilled case - impede convergence. Due to the availability of detailed data on regional human capital, migration and productivity growth, we are able to test how geographic mobility affects convergence via the human capital selectivity of migration. With regard to the endogeneity of the migration flows and human capital, we apply a dynamic panel data model within the framework of ß-convergence and account for spatial dependence. The regressions indicate a positive, robust, but modest effect of a migration surplus on regional productivity growth. After controlling for human capital, the effect of migration decreases; this decrease indicates that skill selectivity is one way that migration impacts growth.

Do reservation wages react to regional unemployment?
21 September 2012
Reservation wages indicate the wage threshold for which individual workers are inclined to supply their working capacity. In important theoretical approaches it is assumed that this threshold depends on the unemployment rate. If this is true, the variation of reservation wages might be an important force behind the regional 'wage curve', which has been estimated in many empirical studies. Up to now, the connection of regional unemployment with reservation wages has not been tested, since research possibilities depend on survey data which were not available. With the 'Labour Market and Social Security' study (PASS), a new large panel survey in Germany, information on regional reservation wages is available. The empirical analysis with this data opens up the 'black box' of the wage generation process and delivers insights about its determining factors. The analysis is based on job matching and efficiency wage theory which are used to derive a relationship between unemployment and reservation wages.

Do literacy and numeracy pay off?
20 September 2012
Is there a reward for basic skills in the German labor market? To answer this question, we examine the relationship between literacy, numeracy and monthly gross earnings of full-time employed workers. We use data from the ALWA survey, augmented by test scores on basic cognitive skills as well as administrative earnings data. Our results indicate that earnings are positively related to both types of skills. There furthermore is no evidence for non-linearity in this relationship and only little heterogeneity when differentiating by sub-groups.

Profiles of local growth and industrial change
17 September 2012
In this paper we take a detailed look at the sectoral anatomy of regional growth in German regions over the period 1978-2008. In the aggregate, the German economy is characterized by a secular decline of the manufacturing sector and a rise of the modern service economy. This trend of structural change (Petty's law) by no means occurs uniformly across space, however. Some regions exhibit this trend even at an accelerated pace, while other regions develop their local economic structures against the trend and expand their manufacturing bases. We first develop a novel empirical approach that allows us to categorize all German regions into one out of three groups with 'pro-trend', 'anti-trend' or 'featureless' regional growth. Afterwards we show that the differential exposure to international trade is an important cause of the divergent patterns of local industrial change.

Employers' selection behavior during short-time work
17 August 2012
During the recession of 2008-09 Germany experienced a huge decrease in GDP. Employment, however, remained surprisingly stable. The so-called German labor market miracle is often ascribed to the intensive usage of short-time work. Despite the resurgence of this instrument, little is known about the employees affected by it. This paper analyzes whether employers select certain individuals for short-time work, where special focus is given on the effect of human capital.

Mothers and Daughters: Heterogeneity of German direct investments in the Czech Republic
27 July 2012
The aim of the paper is to assess the heterogeneity of German affiliates in the Czech Republic and their mother companies in Germany. Applying cluster analysis to firm-level data from the unique IAB-ReLOC survey, we identify four main groups of firms that partition the sample by broad sectoral lines and technological intensity of their operation. More specifically, the principal clusters can be interpreted as: I) High-tech industrial firms; II) Low-tech industrial firms; III) High-tech service providers; and IV) Low-tech service providers. The classification is examined more closely by location, ownership and industry of the firms and in the framework of a probit model. The main result is that there is a significant technological gap between the mothers and their cross-border daughters in industry that cannot be found in the service sector. From this follow implications for technological upgrading on both sides of the border, which are discussed in the concluding section of the paper.

The rise of the East and the Far East
10 July 2012
The authors analyze the effects of the unprecedented rise in trade between Germany and 'the East' - China and Eastern Europe - in the period 1988-2008 on German local labor markets. Using detailed administrative data, they exploit the cross-regional variation in initial industry structures and use trade flows of other high-income countries as instruments for regional import and export exposure. The authors find that the rise of 'the East' in the world economy caused substantial job losses in German regions specialized in import-competing industries, both in manufacturing and beyond.

Assortative matching through signals
29 June 2012
The matching of likes is a frequently observed phenomenon. However, for such assortative matching to arise in a search model, often implausibly strong conditions are required. This paper shows that, once signals are introduced, a search model can generate even perfect assortative matching under weak conditions: supermodularity of the match production function is a necessary and sufficient condition. It simultaneously drives sorting and functions as a single-crossing property ensuring that agents choose truthful signals. The information thereby transmitted allows agents to avoid all unnecessary costs of random search, which creates in effect an almost frictionless environment. Hence the unique separating equilibrium in the model achieves nearly unconstrained efficiency despite frictions.

Asymmetric information and overeducation
18 June 2012
We consider an economy where production may use labor of two different skill levels. Workers are heterogeneous and, by investing in education, self-select into one of the two skills. Ex-ante, when firms choose their investments in physical capital, they do not know the level of human capital prevailing in the labor market they will be active in. We prove existence and constrained inefficiency of competitive equilibria, which are always characterized by overeducation. An increase in total expected surplus can be obtained by shrinking, at the margin, the set of workers investing in high skill. This can be implemented by imposing taxes on the cost of investing in high skill or by imposing a progressive labor earning tax.

Regional disparities in an extended EU
05 June 2012
Within the European Union, economic power, income and employment diverge extensively – both within and also between Member States. The reduction of this gradient is the declared political goal at the European and national levels. Although economic regional research has embraced this topic, hardly any reliable findings are available as to the extent of the effect that eastwards expansion and the economic integration of the EU have had on the development of regional disparities. Moreover, to what extent and why the development of employment at various different levels of qualification is different from region to region is still largely unexplained. Based on a wide collection of data and econometric analyses, Friso Schlitte's study "Regional Disparities and Growth in the European Union" makes an important contribution to closing these gaps in research. He demonstrates the following for example: The presence of a large number of highly qualified persons also raises the labour market chances of persons with low qualifications in the region. However, the stricter the separation of the scope of duties of differing qualification levels within an enterprise, the less favourable the development of the opportunities for persons with low qualifications.

Income: Do sons have similar ones to their fathers?
08 May 2012
From dishwasher to millionaire – hardly anyone manages that, either in the United States or Germany. And it is even more difficult for people whose parents already had low earnings. Social advancement from the parental generation to that of the child seldom takes place. That is one of the central research results presented by the book "Inter- and intragenerational economic mobility". The author, Daniel D Schnitzlein, examines the causes of economic mobility, comparing Germany to the United States and Denmark. He also analyses the economic mobility of siblings as well as the influence of cultural backgrounds. However Dr Schnitzlein does not only take a comparative look beyond Germany's borders: his research also revolves around the development of wage mobility in the eastern and western parts of Germany itself, concentrating on mobility within a generation.
The author Daniel D Schnitzlein completed his doctorate at the University of Erlangen-Nuremberg and is currently a researcher on the SOEP longitudinal study (socioeconomic panel) at the German Institute for Economic Research (DIW) in Berlin.

Between familial imprinting and institutional regulation
29 March 2012
In this paper, I examine how family related employment interruptions for women in the FRG (Federal Republic of Germany) and the GDR (German Democratic Republic) looked like in the period prior to German reunification. Furthermore, I investigate how career interruptions developed after the German reunification in the old and new states and whether a convergence of re-entry behaviour can be observed. Following research questions are addressed: Which factors are more important: attitudes towards the employment of mothers, which were transferred through socialisation in childhood and adolescence, or institutional arrangements shaped by parental leave regulations? Based on data from the IAB ALWA study ('Working and Learning in a Changing World'), the results show that even twenty years after the German reunification, significant differences between women in East and West Germany are found to exist with respect to family related employment interruptions.

International trade, technical change and wage inequality in the U.K. economy
21 March 2012
This paper examines the joint impact of international trade and technical change on U.K. wages across different skill groups. Results show that real wages of skill groups are driven by the sector bias of price change and TFP growth of selected sectors of production. Furthermore, for each year 1970-2005 we estimate the share of the three different skill groups on added value which indicate structural change in the U.K. economy. Empirical results show a structural change in the U.K. economy by the declined share of low-skilled workers and the increased share of medium-skilled and high-skilled workers over the years.

International trade and collective bargaining outcomes
21 March 2012
In theoretical trade models with variable markups and collective wage bargaining, export exposure may reduce the exporter wage premium. We test this prediction using linked German employer-employee data from 1996 to 2007. To separate the rent-sharing mechanism from assortative matching, we exploit individual worker information to construct profitability measures that are free of skill composition. We find that rent-sharing is less pronounced in more export intensive firms or in more open industries. The exporter wage premium is highest for low productivity firms. In line with theory, these findings are unique to the subsample of plants covered by collective bargaining.

The analysis relies on rich German establishment data and reveals new insights in the institutional machinery of wage bargaining: While the existence of such clauses is related to higher wages (11 %), their application results in wages cuts of roughly the same size. Regarding works councils the results suggest that they are able to prevent negative wage effects of opening clauses on average.

Foreign direct Investment and search unemployment
01 March 2012
This paper proposes a simple multi-industry trade model with search frictions in the labor market. Unimpeded access to global financial markets enables capital owners to invest abroad, thereby fostering unemployment at the extensive industry margin. Whether a country benefits from FDI in terms of unemployment depends on the respective country's net-FDI, measured as the difference between in- and outward FDI. The derived FDI and unemployment nexus is tested employing macroeconomic data for 19 OECD countries on unemployment, FDI, and labor market institutions. Results support the model in that net-FDI is robustly associated with lower rates of aggregate unemployment.
