    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.

    The impact of low-skilled immigration on female labour supply

    19 November 2013
    This paper contributes to the literature on the impact of immigrants on native female labour supply. By segmenting the market by educational levels, the authors are able to investigate which nativeborn women are more affected by an increase of low-skilled immigrants working in the household service sector. They present a model of individual choice with home production, using an harmonized dataset (CNEF) and test its main predictions.

    Recruiting abroad: the role of foreign affinity and labour market scarcity

    15 November 2013

    The author study the recruiting behaviour of German establishments with regard to the use of foreign labour markets. The results indicate that shortages are functional and foster the use of foreign labour markets, but the large effect of foreign affinity also reveals that the potential of immigrant workers is used selectively.

    The cyclicality of worker flows: Evidence from Germany

    05 November 2013

    The development of unemployment and employment is strongly determined by labor market flows. This dissertation analyzes worker flows, i.e. job findings and separations, over the business cycle. The analysis uses process-generated micro data provided by the Institute for Employment Research (IAB), which allow gaining comprehensive insights into labor market dynamics in Germany.

    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.

    Migration, unemployment, and skill downgrading

    13 September 2013

    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.

    Unemployment benefit II, unemployment and health

    13 September 2013

    A multitude of studies has established a negative relationship between unemployment and health. With the "Hartz-reforms", unemployment benefit II was introduced in 2005. Whether unemployment benefit II receipt has an impact, additional to unemployment, on health, is investigated. For this study data of the panel study "Labour market and social security" is used. The sample consists out of 14.282 respondents aged 18 to 65, who participated up to five years from 2006 to 2011. Measures of subjective health by social status were analyzed using Fixed Effect panel models.

    New insights into the development of regional unemployment disparities

    26 August 2013

    Large regional unemployment disparities are a common feature of the labor market in many countries. This study deals with the question whether regional unemployment disparities in western Germany widen, become narrower or remain constant over time. It examines the hypothesis of convergence for regional unemployment rates of western German Federal States and the time period 1968 to 2009 following different concepts of convergence.

    Mismatch unemployment

    22 August 2013

    This paper provides detailed empirical evidence on the scope of mismatch in Germany in the past decade, using a comprehensive administrative data set that allows for disaggregation at the levels of industry, occupation and region. The results provide no evidence that the Hartz reforms have substantially reduced mismatch, in line with the fact that reallocation across occupations appears not to have been eased.

    Using Census and Population Registers data from 20 OECD destination countries, the IAB has released a new dataset featuring the number of immigrants by gender, educational level, country of origin and destination, for the years 1980-2010.

    The data collection has been carried out within the framework of the European project TEMPO (TEmporary Migration, integration and the role of POlicies), with the aim of providing researchers with a new and up to date tool for the study of the causes and consequences of international migration, and of the out-migration of the high-skill population (the so-called "Brain Drain").

    Skilled labour requirements in firms

    30 July 2013

    Cover IAB-Forum 1/2013Establishments 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

    27 June 2013

    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 scars of youth

    27 May 2013

    Does early-career unemployment cause future unemployment? 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.

    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.

    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.

    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.

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

    Cover IAB-Bibliothek 333Within 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.

    IAB-Bibliothek 322 CoverFrom 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.

    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.

    So far little empirical evidence exists on how real wages of newly hired workers react to business cycle conditions.

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.

    The time trend in the matching function

    29 February 2012

    We revisit the puzzling finding that labour market performance appears to deteriorate, as suggested by negative time trends in empirical matching functions. We investigate whether these trends simply arise from omitted variable bias. Concretely, we consider the omission of job seekers beyond the unemployed, the omission of inflows as opposed to stocks, and the failure to account for vacancy dynamics. We first build a model of all labour market flows and use it to construct series for these flows from aggregate data on the U.S. labour market. Using these series, we obtain a measure for employed and non-participating job seekers. When we thus include all job seekers, the estimated time trend remains unchanged. We similarly obtain measures for inflows into unemployment and vacancies.

    Dynamics on the European labour markets: Are insecure contracts the price of more employment?

    13 February 2012

    Cover IAB-Brief Report 25/2011In many EU countries labour market policy moved in the 1990s towards a stronger employment orientation. We address the question of whether European labour markets have become more inclusive after a period of intense labour market reforms and just before the adverse effects of the economic crisis took effect. We do this for the following countries: Belgium, Czech Republic, Denmark, France, Germany, Great Britain, Hungary, Italy, Poland and Spain. Based on ELFS data we estimate the probability of someone who was either unemployed or inactive, making the transition a) to any form of employment and b) that the transition has been made to permanent compared to a temporary or marginal part-time contract. Our results show that the chances to make a transition into employment have increased on average across all countries although there are considerable country variations. In most - but not all - countries, however, increasingly inclusive labour markets are associated with a reduction in job quality, as measured by contract type.

    Regional unemployment disparities in Germany

    10 January 2012

    Cover IAB-Bibliothek 331Disparities in the regional unemployment rates in Germany are more distinct, the smaller the regional level of observation. Furthermore, the adjustment of smaller spatial units to labour market shocks is found to work predominantly through labour mobility and less through the unemployment and the participation rate. The speed of adjustment in the unemployment rate does instead not vary substantially between Federal States and districts. The distribution of regional unemployment rates thereby displays strong persistence and does not show convergence towards the national unemployment rate, but convergence towards the region-specific means. Labour market adjustment mechanisms work efficient as labour demand shocks disappear within only a few years. The estimates additionally show that substantial migration and commuting activities are responsible for this efficiency.

    Unemployment and occupational mobility at the beginning of employment career in Germany and the UK

    12 December 2011

    The beginning of one's employment career is often associated with phases of unemployment. The author argues that unemployment has different implications for different educational groups as regards future employment careers depending on institutional settings in the UK and Germany. While search and matching models imply that an unemployment phase might be used for an active job search and might therefore result in a better position, human capital and signalling theory predict status losses.

    The gender gap of returns on education across West European countries

    13 October 2011

    We study the returns on education in Europe in a comparative perspective. We extend the model of de la Fuente [(2003). Human Capital in a Global and Knowledgebased Economy. part II: Assessment at the EU Country Level. Report for the European Commission], by estimating the values of the relevant parameters for men and women and introducing several variables specifically related to maternity leaves and benefits. As a preliminary step, we evaluate the effect of education on the wage profile. We estimate the Mincerian coefficients for 12 West European countries using the EU-SILC data for 2007 and use them as input in the optimisation problem of the individual to calibrate the model. Finally, we analyse the impact and relevance of several public policy variables. In particular, we evaluate the elasticities of the returns on education with respect to unemployment benefits, marginal and average tax rates, maternity leaves and childcare benefits.

    Trade liberalisation, technical change and skill-specific unemployment

    04 October 2011

    The aim of this paper is to formalise a two-country model of trade liberalisation and technical change with heterogenous firms and search-and-matching frictions in the labour market. By considering different sectors and factors of production we allow for comparative advantages and study the trade and technology effects within and between sectors on wages and employment of skilled and low-skilled workers. Technical change together with inter-sectoral trade has distributional consequences across the labour force, favouring the skilled against the low-skilled workers. Intra-sectoral trade counteracts as it increases the demand for low-skilled workers, too. The overall effects on wages and employment of skilled and low-skilled workers depend on the extent of technical change, inter-sectoral trade and intra-sectoral trade.

    Do small labor market entry cohorts reduce unemployment?

    13 September 2011

    In this paper we study the effect of small labor market entry cohorts on (un)employment in Western Germany. From a theoretical point of view, decreasing cohort sizes may on the one hand reduce unemployment due to “inverse cohort crowding” or on the other hand increase unemployment if companies reduce jobs disproportionately. Consequently, the actual effect of cohort shrinking on (un)employment is an empirical question. We analyze the relationship between (un)employment and cohort sizes using a long panel of Western German labor market regions.

    The outcome of coaching and training for self-employment

    01 August 2011

    This paper focuses on the question of whether improving the competence of new business founders by means of coaching and training programs enhances the dura-tion of self-employment. In the analysis the autors focus on support activities that are pro-vided in addition to a financial subsidy and which mainly focus on providing external expertise for founders who started a business from a position of unemployment. They find that the inflow into the related schemes is strongly determined by regional pat-terns and time while individual characteristics are less important. This reflects a par-ticular regional specialization in the set-up of the promotion of self-employment. A statistical matching approach is used to control for selectivity and is performed in a way that explicitly takes into account differences across regions and over time. The results show that treatment effects tend to be insignificant in statistical and economic terms. They also find evidence that external expertise reduces the duration of self-employment.

    Labor market integration of foreigners

    11 May 2011

    Cover IAB-Bibliothek Volume 327Contrary to the widespread procedure of seeing migrants as deficient actors and of putting their integration difficulties into the forefront, the perspective in this book has been readjusted and concentrates on the potential that immigration offers. Migration – and the cultural diversity induced by it – means that people with new ideas, experiences and strategies for solving problems are coming to Germany. If one knows how to harness this potential within economic processes then immigration can stimulate economic growth and thus send out positive impulses to the labour market.

    Start-ups by migrants: A path towards economic and social integration

    21 April 2011

    In comparison to other countries, there are not many start-ups in Germany. This is shown by the "Global Entrepreneurship Monitor" (GEM) of 2010 which thus also confirms earlier results. What is remarkable is that migrants tend to set up their own businesses more often than local people. In doing so, they have specific advantages. For example it is tendentially easier for them to export their products and services. In addition there are signs that they have more role models than local start-up entrepreneurs. However there is also indication that start-ups by migrants are often a reaction to their comparatively poor chances on the labour market.

    A new targeting - a new take-up?

    14 April 2011

    The authors present first estimates of rates of non-take-up for social assistance in Germany after the implementation of major social policy reforms in 2005. The analysis is based on a microsimulation model, which includes a detailed description of the German social assistance programme. Their findings suggest a moderate decrease in non-take-up compared to estimates before the reform. In order to identify the determinants of claiming social assistance, the authors estimate a model of take-up behaviour which considers potential endogeneity of the benefit level. The estimations reveal that the degree of needs, measured as the social assistance benefit level a household is eligible for, and the expected duration of eligibility are the key determinants of the take-up decision, while costs of claiming seem to play a minor role.

    The intergenerational transmission of educational attainment in East and West Germany

    17 February 2011

    Socialist societies often emphasized the abolition of traditional social classes. To achieve this objective, educational opportunities were at times 'actively managed' and allocated to children of less educated parents. What happened to these patterns after the demise of socialist rule in Eastern Europe? The authors study the development of educational mobility after the fall of the iron curtain in East Germany and compare the relevance of parental educational background for secondary schooling outcomes in East and West Germany. Based on data from the German Mikrozensus they find that educational mobility is lower in East than in West Germany and that it has been falling in East Germany after unification. While the educational advantage of girls declined over time, having many siblings presents a more substantial disadvantage in East than in West Germany.

    Persistence of regional unemployment

    14 February 2011

    In this paper, the authors present a new econometric approach to the study of regional unemployment persistence, in order to account for spatial heterogeneity and/or spatial autocorrelation in both the levels and the dynamics of unemployment. They propose an econometric procedure suggesting the use of spatial filtering techniques as a substitute for fixed effects in a panel estimation framework. The authors present several experiments in order to investigate the spatial pattern of the heterogeneous autoregressive parameters estimated for unemployment data for German NUTS-3 regions. They find widely heterogeneous but generally high persistence in regional unemployment rates.

    Flexible working times foster economic growth

    26 January 2011

    That the German economy was able to achieve high growth rates in 2010, so soon after the crisis, was largely due to flexible working times. Employees' average annual working time rose by 2.3 per cent, for instance through the ending of short-time work, the return to normal company working hours, the reduction of credit hours on working time accounts, and more overtime.

    Wage rigidity

    25 January 2011

    In times of crisis, employers tend to resort to dismissals instead of the medium of reduction in nominal wages. This may be due to the influence of the trade unions, the inflexibility of company wage systems, or possibly also norms of fairness. What effect do downwardly rigid wages have on the labour market? Do they lead – in conjunction with a lower inflation rate – to higher unemployment? This IAB info platform presents scientific literature on the topic of wage rigidity.

    Selective immigration policies, migrants' education and welfare at origin

    24 January 2011

    Destination countries are progressively shifting towards selective immigration policies. These can effectively increase migrants' average education even if one allows for endogenous schooling decisions and education policies at origin. Still, more selective immigration policies reduce social welfare at origin.
