    Colloquium: The effect of recent labour market oriented immigration from EU member states on wage dynamics in Germany

    19 March 2018

    In our discussion series „Labour market and occupational research“ Dr. Matthias Hertweck from the Deutsche Bundesbank (German Federal Bank) investigates the wage impact of recent fairly strong labour market oriented net immigration flows from EU member states to Germany. The analysis is based on a modified approach to estimating wage growth in Germany taken in the Bundesbank macroeconometric model. The results indicate that recent net immigration from EU member states to Germany reduced annualised wage growth by almost 1 percentage point on average over the past two years. Even when taking into account the wage effect of net immigration, tight labour market conditions contributed strongly to upward wage pressure in recent years. At the same time, wage growth contributions of low inflation rates and relatively weak productivity growth were below average.

    The discussion series "Labour Market and Occupational Research" is a forum where primarily external researchers present the results of their work and discuss these with experts from the IAB. The colloquium with Dr. Matthias Hertweck from the Deutsche Bundesbank takes place in conference room E10, Regensburger Street 100, 90478 Nürnberg on March 21st, 2018 at 2 pm.


    Long-term unemployment: a European comparison

    23 February 2018

    Long-term unemployment: a European comparisonFor many years, Germany was notable for its high levels of long-term unemployment compared to other countries. However, in contrast to the European trend, the number of long-term unemployed has decreased significantly since the mid-2000s. In most other European countries the number of long-term unemployed rose to a greater or lesser degree as a result of the financial and Euro debt crisis.

    German FDI in the Czech Republic – Employment effects in the home country

    22 February 2018

    Do investments in the Czech Republic lead to employment growth or employment losses in the German firms involved? To address this question, a unique database about German firms with foreign direct investment (FDI) in the Czech Republic and firms without FDI in any country has been established within the IAB-ReLOC project. By developing a new method for linking firm-level data with establishment-level data of the Institute for Employment Research (IAB), this database is now linked with the IAB employment data. As the exact dates of the investments in the Czech Republic are known, the employment development of firms with Czech affiliates and firms without FDI is compared for the same time periods.

    The Timing of Structural Labor Market Reforms Matters

    09 February 2018

    The Timing of Structural Labor Market Reforms Matters Ever since the economic and financial crises of the late 2000s – also known as the Great Recession –, demands for structural reforms to ease market regulations have been omnipresent in Europe. A particular emphasis has been placed on labor market regulations – involving heated political debates. A recent IAB study shows that the effects of labor market reforms heavily depend on the timing of the reform.

    Graduate migration in Germany – new evidence from an event history analysis

    05 February 2018
    This study use administrative social security records and event history methods to investigate graduate migration in Germany. The results indicate that most migration events happen up to seven years after graduation. Work experience gathered before and during the studies influences the migration decision, pointing to the importance of labour market contacts and social networks. In contrast to previous studies we do not detect a genuine negative duration dependence for the probability of leaving the region of study. When labour market entry outside the university region is considered there is some indication for cumulative stress.

    The flow of migrants to Germany and their integration into the labour market

    26 January 2018

    MigrationSince 2015, questions around migration and the integration of migrant men and women into the labour market, the education system and all other areas of society have moved into the centre of public and political discourse. A key focus of interest is the high level of refugee migration in 2015, which represented a historical peak, unmatched since the founding of the Federal Republic of Germany.

    Labor Markets and Labor Mobility in the French-German Border Region

    22 January 2018
    This paper examines the cross-border labor market in the French-German Upper Rhine Region. Based on shortage analyses conducted for both sides of the border, a fixed effects panel regression estimates the impact of changing labor market situa-tions on the number of French frontier workers. Although some of the anticipated effects are detected, their size is rather modest and insufficient to balance regional disparities in a way that would be expected in a fully integrated cross-border labor market. By the same token, the quantitative analysis identifies standardized certifi-cates as a barrier to cross-border mobility and confirms a preference of frontier workers for routine tasks. In addition, insufficient public transportation and language skills, missing information about the neighboring country as well as problems with the recognition of degrees are also found among the obstacles to an integrated labor market.

    The Organizational Design of High-Tech Startups and Product Innovation

    04 January 2018

    In this study they investigate whether appointing a middle management level affects startups’ innovation performance. Additional hierarchical levels are often suspected to restrict innovative activities. However, founders’ capacities for information processing and resource allocation are usually strongly limited while, at the same time, R&D decisions are among the most consequential choices of startups. They argue that middle management is positively related to introducing product innovations because it improves the success rates from recombining existing knowledge as well as managing R&D personnel. In addition, we suggest that the effectiveness of these mechanisms depends on the riskiness of a startup’s business opportunity. Based on a sample of German high-tech startups, they find support for our conjectures.

    Longer maternity leave – healthier mothers?

    21 December 2017

    Leave policies allowing parents to take time off work after childbirth are considered an important measure to buffer the stresses associated with childrearing and gainful employment. Despite reducing this double burden, longer leave periods do not necessarily support the return of healthier mothers into the labor market.

    Job Matching on Connected Regional and Occupational Labor Markets

    19 December 2017

    Job mobility equilibrates disparities on local labor markets and influences the efficiency of the job matching process. In this paper, they describe a job matching model that allows for simultaneous regional and occupational mobility, predicting corresponding spillover effects on the number of matches. They estimate these spillover effects based on novel administrative German data on the number of matches, unemployed, and vacancies of local labor markets, which they define as distinct occupations in distinct regions.

    Formal Search and Referrals from a Firm’s Perspective

    04 December 2017

    This study explores the relationship between frms’ characteristics and their recruitment strategies. They propose a model based on a search and matching framework with two search channels: a formal channel which is costly for frms and a costless informal channel, i.e. referrals. There is a continuum of heterogeneous vacancies in our model where every firm with an open vacancy chooses an optimal search effort in order to attract job candidates. This search effort depends on the productivity of the firm and, contrary to the previous literature, workers send simultaneous applications to open vacancies. We assess the model predictions by using the IAB Job Vacancy Survey, a representative Survey among human resource managers in Germany reporting information about their most recent recruitment case.

    Walking between the worlds – labour market economist and former Secretary of State Pedro S. Martins

    19 October 2017

    Pedro S. MartinsPedro S. Martins is an expert spanning boundaries between science and politics: Martins, who is now doing research at Queen Mary University of London, was Secretary of State in the Ministry for Economics and Employment of his home country Portugal from 2011 until 2013.  At a time when unemployment, especially among the youth, achieved a record high across Southern Europe as a result of the economic and financial crisis. As a politician, he got a once-in-a-lifetime opportunity to combat job crisis by implementing measures that he himself had always advocated as a researcher.  

    In an interview to the IAB-Forum magazine, he airs his assessments and experience.

    Quantifying the effect of labor market size on learning externalities

    13 October 2017

    We show for Germany that labor productivity as reflected in wage is, ceteris paribus, higher for workers who previously acquired work experience in rather urban labor markets with a large local workforce than in rather rural labor markets which are small in terms of regional employment. Our empirical analysis provides new evidence on the magnitude of these dynamic agglomeration gains by estimating the elasticity of wages with regard to the (cumulated) size of the local labor markets in which workers acquired experience.

    The creation and resolution of working hour discrepancies over the life course

    21 September 2017
    Studies on labor supply have increasingly taken account of not only the actual working hours, but also of working hour preferences as well as the discrepancy between them. However, longitudinal research on this topic remains scarce. This paper contributes to the analysis of working hour discrepancies by exploring how hours mismatch emerges and resolves with special consideration of the household context.

    Counteracting unemployment in crises: Non-linear effects of short-time work policy

    13 September 2017

    Short-time work is a labor market policy that subsidizes working time reductions among firms in financial difficulty in order to prevent layoffs and stabilize employment. Many OECD countries have used this policy in the Great Recession, for example. This paper shows that the effects of discretionary short-time work are strongly time dependent and non-linear over the business cycle.

    Regional mobility of unemployed workers

    11 August 2017

    Modern labour markets are characterised by the high levels of flexibility they demand of workers and unemployed individuals in particular. Increasing the willingness of jobseekers for regional mobility is an integral part of this development and was at the heart of the far reaching Hartz reforms of the German labour market in the early 2000s. Within this context, this research assesses the role regional mobility plays in the job search of unemployed individuals.

    Knowledge Intensive Business Services (KIBS) are widely perceived as being important drivers of technological progress and innovation. KIBS are generally understood as depending, driving and thriving on knowledge exchanges and therefore, geographical proximity to markets, customers and suppliers would be expected to be a critical factor in their performance. This paper investigates how the innovation performance and processes of KIBS firms are related to their distance from the nearest city and also to the size of the nearest city.

    The number of commuters and the distances of home-to-work travel have increased in recent decades. Based on a previous study that proposed a new approach for delineating functional labour market regions, this paper focuses on the temporal stability of delineations of labour market regions in Germany. In a comparison of the best delineations among pooled groups of three years beginning in 1993, regions are classified as core regions, related regions or overlapping regions. The main finding is that regions surrounding important labour market centres form stable labour markets. Over time, most employees belong to the same labour market region or parts of it.

    What harmonised and registered unemployment rates do not tell

    11 July 2017
    The most commonly used statistical sources for the analysis of unemployment are registered unemployment (RU) at the national level and internationally harmonised unemployment data provided by the European Labour Force Survey (EU-LFS) ac-cording to the International Labour Organisation (ILO) standard. The logic behind both unemployment statistics is to count people "without work" only when they are “actively looking” and “available for work”.
    This methodological study provides an in-depth analysis of the discrepancies between registered unemployment (RU) and internationally harmonised unemployment (LFS-U) in a comparative view. For ten selected EU-countries (Austria, Finland, France, Germany, Ireland, Netherlands, Poland, Spain, Sweden and the UK) they show in which countries the registers are more restrictive than the survey and vice versa.

    Where Did All the Unemployed Go?

    12 June 2017

    The number of unemployed workers in Germany decreased dramatically from its peak in February 2005 at over 5.2 million to 3.6 million by 2008. At the same time, employment increased by 1.2 million. Most theoretical and empirical analyses of this episode assume that a worker leaving unemployment moves into full employment. We ask where the unemployed actually went. Using and merging two large micro data sets, we account for the decrease of unemployment by computing inflows and outflows between unemployment and 16 other labour market states.

    Does Participating in a Panel Survey Change Respondents’ Labor Market Behavior?

    03 May 2017

    Panel survey participation can bring about unintended changes in respondents’ behavior and/or reporting of behavior. Using administrative data linked to a large panel survey, we analyze changes in respondents’ labor market behavior. We estimate the causal effect of panel participation on the take-up of federal labor market programs using instrumental variables. Results show that panel survey participation leads to a decrease in respondents’ take-up of these measures. These results suggest that panel survey participation not only affects the reporting of behavior, as previous studies have demonstrated, but can also alter respondents’ actual behavior.

    The relevance of personal characteristics and gender diversity for (eco) - innovation activities at the firm-level

    10 April 2017

    Up to now, the growing literature on the determinants of eco-innovation has not considered the influence of personal characteristics of the employees of a firm. The existing econometric analyses show much "noise" explaining the driving forces of eco-innovation. The paper tries to open the "black box" of unexplained heterogeneity. In fact, latent variables such as the greenness of a firm may be explained by the per-sonal characteristics (gender, family status, geographical origin, education etc.) of the staff and the decision makers in a firm.

    Child care reforms and labor participation of migrant and native mothers

    20 March 2017

    As in other countries, also in Germany there has been large political effort to increase mothers’ labor participation through child care provisions. However, it is an open question whether the latest child care reforms of 2013 are successful in this sense. While the introduction of a home care allowance, the so called ‘Betreuungsgeld’, for families not using public child care for their children aged one and two years was expected to have negative effects, the introduced legal claim for public child care for children of the same age group should increase the use of public child care and therefore speed up the mothers’ return to work after child birth.

    Apprentice Poaching in Regional Labor Markets

    08 March 2017

    A number of studies have found that firms provide less training if they are located in regions with strong labor market competition. This finding is usually interpreted as evidence of a higher risk of poaching in these regions. Yet, there is no direct evidence that regional competition is positively correlated with poaching. Building on a recently established approach to expost identify poaching of apprenticeship completers, our paper is the first to directly investigate the correlation between regional labor market competition and poaching.

Using detailed administrative data, they exploit cross-regional variation in the conditional policy styles of local employment agencies and use this fuzzy discontinuity as an instrument for program participation. They find that subsidies significantly increase cumulative employment duration and earnings for the subgroup of compliers. These gains are particularly pronounced for workers who are women, younger than 35 years old, non-German citizens and participated before the economic crisis of 2009.

    Offshoring and Firm Overlap

    22 February 2017

    The authors set up a model of offshoring with heterogeneous producers that captures two empirical
    regularities of German offshoring firms. There is selection of larger, more productive firms
    into offshoring. However, the selection is not sharp, and offshoring and non-offshoring firms
    coexist over a wide range of the revenue distribution.

    Labour Market Effects of Wage Inequality and Skill Biased Technical Change in Germany

    14 February 2017

    This paper analyses the relationship between wage inequality and labour market development. Relevant economic theories are ambiguous, just as public debates. We measure the effects of wage inequality, skill-biased and skill-neutral technology on hours worked, productivity and wages in a novel structural vector error correction framework identified by non-recursive long-run restrictions.

    The role of employer, job and employee characteristics for flexible working time

    07 February 2017

    Modern working societies face the challenge to combine the establishments’ with the employees’ needs for working-time flexibility. The authors investigate the determinants of overtime and different working hours’ arrangements using the German Linked Employer-Employee Study of the Socio-Economic Panel (SOEP-LEE) and logistic regression models. The results show that employer and job characteristics are most important for determining overtime and the different working hours’ arrangements, underlining the power of employers with regard to working-time flexibility.

    Early termination of vocational training: dropout or stopout?

    30 January 2017

    This paper studies the factors that influence the beginning of either a new vocational training in another occupation (stopout) or the stop of vocational training altogether after an early termination (dropout of the vocational system). One influencing factor is the amount of the human capital acquired which is determined by the duration of (early terminated) vocational training.

    In the recent years an intensive discussion in politics, research, business and socie-tyon the influence of digitalisation on the working world has evolved. This developmentis expected to exert profound effects on the use of human labour. However, judgements widely diverge. The comprehensive debates on “industry 4.0” and “labour 4.0” in Germany are concerned with influences of digitalisation on the economy and the labour market, substitutability of jobs as well as conditions, qualificationsand regulations for a new world of employment.

    The valuation of changes in commuting distances: An analysis using georeferenced data

    22 December 2016

    We analyze the causal effect of commuting on wages, using a large sample of German Job changers. Information on their home and workplace addresses in combination with road navigation software allows us to calculate exact door-to-door commuting distances with an unprecedented degree of precision. We use a theoretical model on spatial job search to motivate our empirical strategy. By focusing on job moves, we can use panel data techniques and control for unobserved individual heterogeneity.

    The Effects of Immigration on Household Services, Labour Supply and Fertility

    08 December 2016

    Fertility and female labour force participation are no longer negatively correlated in developed countries. Recently, the role of immigration has been put forward as a driving factor among others. Increased immigration affects supply and prices of household services, which are relevant for fertility and employment decisions. This paper analyses the effect of immigration on labour supply and fertility of native women in the UK, with a focus on the role of immigration on household services. Adopting an instrumental variable approach based on the country-specific past distribution of immigrants at regional level, I find that immigration increases female labour supply, without affecting fertility. My results show that immigration increases the size of the childcare sector, and reduces its prices, suggesting that immigrants may ease the trade-off between working and child rearing among native women.

    Patterns and impact of longitudinal measurement error for welfare receipt

    30 November 2016

    Measurement error is a common phenomenon in the empirical sciences. Longitudinal data can especially be affected by it, as measurement error can influence measures of change, which is one of the primary reasons for collecting longitudinal data in panel surveys. However, measurement error in longitudinal data is rarely analysed.

    In this series of papers, the measurement error for welfare receipt is analysed for up to five consecutive panel waves by linking panel survey data with administrative data on the individual level. Results from all four studies suggest that measurement error for welfare receipt is highly differential. The measurement error for welfare receipt is not based on a random process, but based on personal characteristics and the welfare histories of the respondents.

    Cohort size and youth labour-market outcomes: the role of measurement error

    31 October 2016

    Using data from 49 European regions covering 2005-2012, this paper finds that the estimated effect of cohort size on employment and unemployment outcomes is very sensitive to the age range of the sample. We argue that this is because the identifica-tion strategy commonly used in this literature is unable to eliminate the bias caused by measurement error in the cohort-size variable. The latter arises because large shares of the young choose to acquire education and consequently the size of an age group provides a poor measure of age-specific labour supply. In our view older age groups provide a more suitable sample to test the implications of cohort crowd-ing since the former will have largely entered the labour market. Using a sample aged 25–29, which has relatively low rates of participation in education, we find ro-bust evidence that an increase in cohort size increases employment and reduces unemployment.

    The EU Gender Earnings Gap: Job Segregation and Working Time as Driving Factors

    25 October 2016

    This paper estimates size and impact factors of the gender pay gap in Europe. It adds to the literature in three aspects.  In addition, the fact that part-time positions are more frequent among women notably contributes to the gap. We conclude that policies aiming at closing the gender pay gap should focus more on the sector level than on the aggregate economy.

    The migration of professionals within the EU: any barriers left?

    20 October 2016

    Despite the effort at EU level to harmonize the process of recognition of foreign educational qualifications, the European states differ in their propensity to accept high-school and academic certificates obtained in other EU member states. In turn, a country’s higher degree of recognition of foreign qualifications might be an attractor of non-native skilled workers. We provide evidence on this issue using new data on the outcome of the recognition process in every EU country. Estimating different panel data gravity models, we find that the migration rate to a given destination country is positively affected by its propensity to recognize foreign educational qualifications.

    Management Practices and Productivity in Germany

    17 October 2016

    Based on a novel dataset, the “German Management and Organizational Practices” (GMOP) Survey, we calculate establishment specific management scores following Bloom and van Reenen as indicators of management quality. We find substantial heterogeneity in management practices across establishments in Germany, with small firms having lower scores than large firms on average. We show a robust positive and economically important association between the management score and establishment level productivity in Germany. This association increases with firm size. Comparison to a similar survey in the US indicates that the average management score is lower in Germany than in the US. Overall, our results point towards lower management quality being at least in part to blame for the differences in aggregate productivity between Germany and the US.

    Side effects of the new German minimum wage on (un-)employment

    13 October 2016

    In Germany, decreasing collective bargaining coverage and rising wage inequality led to the introduction of a new statutory minimum wage of EURO 8.50 per hour of work. We analyze the relationship between the bite of the minimum wage and employment/ unemployment growth using regional data of the Federal Employment Agency for prime age individuals. We use difference-in-differences type of specifications using a panel of region-age-sex cells. The results do not provide evidence in favor of a reduced employment growth for the analysed groups, nor do they provide evidence for an increase in unemployment growth due to the minimum wage. However, we find an increase in growth of regular employment at the expense of marginal employment.

    Cognitive Skills, Non-Cognitive Skills, and Family Background: Evidence from Sibling Correlations

    11 October 2016

    This paper estimates sibling correlations in cognitive and non-cognitive skills to evaluate the importance of family background for skill formation. Based on a large representative German dataset including IQ test scores and measures of non-cognitive skills, a restricted maximum likelihood model indicates a strong relationship between family background and skill formation. Sibling correlations in non-cognitive skills range from 0.22 to 0.46; therefore, at least one-fifth of the variance in these skills results from shared sibling-related factors. Sibling correlations in cognitive skills are higher than 0.50; therefore, more than half of the inequality in cognition can be explained by shared family background. Comparing these findings with those in the intergenerational skill transmission literature suggests that intergenerational correlations capture only part of the influence of family on children’s cognitive and non-cognitive skills, as confirmed by decomposition analyses and in line with previous findings on educational and income mobility.

    History Dependence in Wages and Cyclical Selection: Evidence from Germany

    06 October 2016

    Using administrative data from Germany, this paper analyzes the relation between wages and past and  current labor market conditions. Specifically, it explores whether the data is more consistent with implicit contract models (Beaudry/DiNardo, 1991) or a matching model with on-the-job search and cyclical selection (Hagedorn/Manovskii, 2013). The data suggests that wages are related to past labor market conditions as contract theories postulate. However, past labor market conditions also affect contemporaneous wages through the evolution of the match qualities over a worker’s job history -the main hypothesis of the selection model. Refining the selection model by taking into account within company job regrading, we find that wages of workers who switched employers and occupations at the same time respond stronger to the cycle than wages of job stayers. In contrast, wages of workers who only switch employers or occupations are not more cyclical than wages of workers who stay at their previous employer and in their previous occupation.

    Natives and Migrants in Home Production: The Case of Germany

    05 October 2016

    In this paper, we assess the impact of international migration, and the induced home-care service labour supply shock, on fertility decisions and labour supply of native females in Germany. Specifically, we consider individual data of native women from the German Socio-Economic Panel and we merge them with the data on the share of female immigrants and other regional labour market characteristics. We find that an increase of the share of female immigrants at the local level induces women to work longer hours and positively affects the probability to have a child. This effect strengthens for (medium) skilled women and, among them, for women younger than 35 years of age. The negative change in household work attitude confirms the behavioural validity of our results.

    Gender gaps of the unemployed - What drives diverging labor market outcomes?

    24 August 2016

    Analyzing gender gaps of unemployed job-seekers, this study uniquely complements the broad literature focussing predominantly on gender gaps of employed workers. I consider a broad range of labor market outcomes, and disentangle the factors driving the labor market gaps of unemployed men and women. I show that unemployed women perform worse on the labor market due to earlier choices in occupations, their labor force attachment, and working time. By contrast, regional labor market disparities including differences of local employment offices, which are assigned to place unemployed job-seekers, are of minor importance.

    Does Personality Matter? The Impact of the Big Five on the Migrant and Gender Wage Gaps

    17 August 2016
    We investigate whether the Big Five Personality Dimensions contribute to explaining gender and Migrant wage gaps by using a linked employer-employee dataset. We expand the scarce literature concerning personality traits and gender wage gaps in Germany and we provide first evidence for the relationship between the Big Five and the migrant wage gap. Our results reveal that the genders differ in their average personality traits, as do migrants and natives. Further, we find significant associations between the Big Five and wages. The magnitude of this relationship varies across the gender and the migratory status. The results of Oaxaca-Blinder wage decompositions suggest that the Big Five significantly contribute to explaining gender and migrant wage gaps.

    Types of FDI and determinants of affiliate size: the classification makes the difference

    16 August 2016

    This paper deals with the measurement of motives for foreign direct Investment (FDI). Due to a lack of information, several indirect measures exist in order to classify multinational firms into the two main types of FDI. While vertical foreign direct investment refers to the international fragmentation of the production process for cost-saving reasons, horizontal foreign direct investment is performed in order to gain access to new markets. One common approach to identify the dominant reason for firms to go abroad is to compare the industry affiliation of the investing company in the home country and the subsidiary in the target country. The question arises as to how reliable this measure is for identifying FDI motives.

    Effectiveness of sequences of classroom training for welfare recipients

    12 August 2016

    Sequences of active labour market programmes (ALMPs) may be part of an intensified activation strategy targeting hard-to-place individuals who may be long-term unemployed and who may encounter extreme difficulty in finding jobs. Such sequences are very common among welfare recipients in Germany, but most studies only evaluate either single ALMPs or unemployed individuals' first ALMP. Thus, I analyse the effects of participation in different sequences of classroom training, unemployment benefit II (UB-II)-receipt and One-Euro-Jobs for West German men and women on different labour market outcomes. Using rich administrative data and a dynamic matching approach, I can control for dynamic selection problems that occur during a sequence.

    A North-South Model of Trade with Search Unemployment

    27 July 2016

    In this paper I build a North-South model of international trade, economic growth and search-frictional unemployment in the North. Growth is driven by a process of creative destruction in the North followed by imitation in the South. I study the effects of intellectual property rights protection and trade liberalization on unemployment and welfare in the North. Intellectual property rights protection decreases unemployment and increases welfare. Trade liberalization increases welfare but has an ambiguous effect on unemployment. It decreases unemployment if workers in the North have a high outside option and increases it if their outside option is low. I provide empirical evidence in support of the last result using data for 20 OECD countries.

Several recent studies note that rising trends in the dispersion of productivity across firms mirror the trends in the wage inequality across workers.

    Does marginal employment promote regular employment for unemployed welfare benefit recipients in Germany?

    14 June 2016

    Marginal employment (ME) is one of the largest forms of atypical employment in Germany. In this study, the authors analyse whether ME has a “stepping stone” function for unemployed individuals, i.e., whether ME increases the subsequent probability of regular employment. This study adds to the literature in the following ways. First, compared to previous studies, it analyses the “stepping stone” function for a more recent time period, i.e., after Germany’s major labour-market reforms (Hartz reforms) at the beginning of the 2000s. Second, the authors use a new administrative data source which includes previously unavailable information on desired labour supply and household composition. Third, they follow recent methodological developments in the evaluation literature by applying a dynamic evaluation approach that has not previously been used to analyse marginal employment.

    Revision of the IAB Job Vacancy Survey

    07 June 2016

    The German Job Vacancy Survey delivers representative data on the number and structure of vacancies in Germany. Such data cannot be derived from other sources and are therefore unique. The survey includes registered and non-registered vacancies. In course of extensive tests and reviews a new extrapolation procedure has been developed. As a result, the aggregate number of vacancies is revised downwards.

    The research report is organised as follows: Firstly, an overview about the aim and content of the German Job Vacancy Survey is given. Subsequently, the evolution of the new extrapolation procedure is described. Thirdly, the new method is presented and it is shown that the adaption of it significantly improves the quality of the Survey results.

    Essays on matching processes and effects of institutional changes on regional and occupational labour markets

    18 May 2016

    The functioning of the labour market and the impact of labour market policies are a long-standing issue in social and political debate. In this respect, labour market research acquires the necessary knowledge and often receives impulses from labour market policy. Conversely, progress in the development of research methods and data mining encourages labour market policymakers to ask new questions that have not been answered yet.

    Michael Stops picks up such developments and focusses on the following three issues:

    Occupational mobility and the job matching Efficiency; The development of job matching efficiency on partial occupational markets before, during and after the years of the German labour market reforms 2003–2005; The employment effect of the National Minimum Wage in the United Kingdom 1999–2012.

    Causes and consequences of the gender-specific migration from East to West Germany

    18 May 2016

    Although the German reunification took place 25 years ago, differences between East and West Germany are still present. Many people reacted to the differences in living standards and living chances between East and West Germany by migrating to the West. This book investigates not only the crucial individual and structural factors for the gender-specific migration of men and women, but also the consequences of the East–West migration in Germany. It is asked: How does migration influence individual incomes? Are East–West migrants happier? Those questions are answered with the focus on gender-specific differences in the migration behavior.

    Occupation-specific matching Efficiency

    13 May 2016

    Based on rich administrative data from Germany, we address the differences in occupation specific job-matching processes where an occupation consists of jobs that share extensive commonalities in their required skills and tasks. These differences can be explained by the degree of standardization (determined by the existence of certifications or legal regulations) in an occupation and the diversity of tasks in an occupation. We find that the matching efficiency improves with higher degrees of standardization and lower task diversity. We discuss the possible mechanisms of these empirical findings in a search theoretic model: as the standardization of an occupation increases or the diversity of tasks decreases, search costs decrease and the optimal search intensity increases. However, the model reveals that higher search intensities can have positive or negative effects on the matching efficiency. We discuss the conditions under which the empirical results can be predicted.

    Do minimum wages increase job satisfaction?

    10 May 2016

    On 1 January 2015 a new statutory minimum wage of EURO 8.50 per hour of work was introduced in Germany. Using a difference-in-differences approach, we estimate effects on worker-level outcomes of continuing employees. The results reveal a meaningful absolute increase in the affected workers' pay satisfaction. The increase in job satisfaction is modest and predominantly driven by changes in pay satisfaction implying only a small effect on all other dimensions of job satisfaction. Moreover, effects from the minimum wage on work engagement and turnover intention are virtually zero.

    Management practices, workforce selection, and productivity

    03 May 2016

    Recent research suggests that much of the cross-firm variation in measured productivity is due to differences in use of advanced management practices. Many of these practices – including monitoring, goal setting, and the use of incentives – are mediated through employee decision-making and effort. To the extent that these practices are complementary with workers’ skills, better-managed firms will tend to recruit higher-ability workers and adopt pay practices to retain these employees.

    Benefits of dense labour markets

    29 April 2016

    We analyse whether the size of the local labour market allows for better matching between job seekers and vacancies, which is thought to enhance productivity. This analysis is based on a large data set providing detailed micro-level information on new employment relationships in Germany. Our results suggest rather small matching benefits. Doubling employment density increases the productivity of new employment relationships by 1.1% to 1.2%. Moreover, the findings indicate that the benefits accrue only to persons experiencing job-to-job transitions and short-term unemployed. We detect no important impact of agglomeration on transitions from long-term non-employed.

    Asymmetric information in external versus internal promotions

    06 April 2016

    Individuals have two possible channels through which to obtain a managerial position: external and internal promotions. Employing the revised German Employment Register, we compare external and internal promotions by using multinomial logit regressions while accounting for workplace heterogeneity. Individual characteristics are hypothesized to exert differential effects because of their observability within and across workplaces. We find that actual working hours are a more important source of information for internal versus external promotions.

    Employment effects of the new German minimum wage

    17 March 2016

    In Germany a new statutory minimum wage of € 8.50 per hour of work was introduced on 1 January 2015. The authors identify employment effects using variation in the establishment-level affectedness. The data allow them to address anticipatory wage adjustments as well as spillover effects within and across workplaces. Difference-indifferences estimation reveals an increase in average wages by 4.8 percent and an employment reduction by about 1.9 percent in affected establishments. These estimates imply an employment elasticity with respect to wages of about -0.3.
