    Kern, Christoph, Ruben L. Bach, Hannah Mautner & Frauke Kreuter (2024): When Small Decisions Have Big Impact: Fairness Implications of Algorithmic Profiling Schemes. In: ACM Journal on Responsible Computing, Jg. 1, H. 4, S. 1-30. DOI:10.1145/3689485

    Abstract

    "Algorithmic profiling is increasingly used in the public sector with the hope of allocating limited public resources more effectively and objectively. One example is the prediction-based profiling of job seekers to guide the allocation of support measures by public employment services. However, empirical evaluations of potential side-effects such as unintended discrimination and fairness concerns are rare in this context. We systematically compare and evaluate statistical models for predicting job seekers’ risk of becoming long-term unemployed concerning subgroup prediction performance, fairness metrics, and vulnerabilities to data analysis decisions. Focusing on Germany as a use case, we evaluate profiling models under realistic conditions using large-scale administrative data. We show that despite achieving high prediction performance on average, profiling models can be considerably less accurate for vulnerable social subgroups. In this setting, different classification policies can have very different fairness implications. We therefore call for rigorous auditing processes before such models are put to practice."

    Kim, Chanwoo (2024): Learning by Hiring New Immigrants in a Frictional Labor Market. In: Changwoo Kim (2024): Essays in Public, Labor, and Macroeconomics, S. 1-102.

    Abstract

    "Analyzing recent immigration from Central and Eastern European (CEE) countries to West Germany, I document that the propensity of German establishments to hire these new immigrants is correlated with their previous hiring experiences from the group. However, no such correlation is found in the hiring of native Germans. Based on these findings, I build an equilibrium search model in which each firm privately learns about the productivity of an immigrant group based on matching outcomes with their immigrant employees. While immigrants are discriminated against due to inaccurate beliefs about their group, natives encounter externalities as firms misjudge the productivity of the new workforce. The calibrated model suggests that CEE immigrants, on average, have a higher match quality than native Germans with German establishments. However, negatively biased beliefs persist about the immigrant group despite the learning-by-hiring process. These misperceptions cause a significant wage gap due to early tenure wage losses for CEE immigrants and diminish the positive impact of immigration on the employment of native Germans."

    Lehweß-Litzmann, René (2024): Die hohe Anziehungs- und Bindekraft von Gesundheits-, Erziehungs- und sozialen Berufen: eine Analyse von Berufswechseln. In: R. Lehweß-Litzmann (Hrsg.) (2024): Fachkräfte für die Daseinsvorsorge, S. 331-394. DOI:10.5771/9783748939689-331

    Abstract

    "Bezogen auf ausgewählte Humandienstleistungsberufe in den Bereichen Gesundheit, Erziehung und Soziales wird in diesem Kapitel das Phänomen des Berufswechsels untersucht. Ziel ist es, mehr über die Attraktivität dieser Berufe und über die Möglichkeit einer Rekrutierung zusätzlicher Beschäftigter herauszufinden. Die verwendeten Daten stammen aus Betriebsmeldungen an die Sozialversicherung für die Jahre 2013 bis 2019. Die Befunde sind als Indizien dafür zu lesen, dass die untersuchten Berufe für Beschäftigte attraktiv sind: Erstens liegt die Berufstreue hoch, verglichen mit anderen Berufen. Zweitens sind Humandienstleistungsberufe häufiger Ziel als Quelle von Berufswechseln. Zudem kommen Seiten- und Quereinsteiger:innen nicht selten aus einfachen Dienstleistungstätigkeiten außerhalb des Care-Bereichs, womit Humandienstleistungsberufe berufliche Aufstiege ermöglichen."

    Lipowski, Cäcilia, Anna Salomons & Ulrich Zierahn-Weilage (2024): Expertise at Work: New Technologies, New Skills, and Worker Impacts. (ZEW discussion paper 24-044), 83 S.

    Abstract

    "We study how new digital technology reshapes vocational training and skill acquisition and its impact on workers’ careers. We construct a novel database of legally binding training curricula and changes therein, spanning the near universe of vocational training in Germany over five decades, and link curriculum updates to breakthrough technologies using Natural Language Processing techniques. Our findings reveal that technological advances drive training updates, with curriculum content evolving towards less routine intensive tasks, and greater use of digital and social skills. Using administrative employer-employee data, we show that educational updates help workers adapt to new demands for their expertise, and earn higher wages compared to workers with outdated skills. These findings highlight the role of changes in within occupational skill supply in meeting evolving labor market demands for non-college educated workers." (Author's abstract, IAB-Doku) ((en))

    Lo, Ming Sum Simon & Ralf A. Wilke (2024): A single risk approach to the semiparametric competing risks model with parametric Archimedean risk dependence. In: Journal of Multivariate Analysis, Jg. 201. DOI:10.1016/j.jmva.2023.105276

    Abstract

    "This paper considers a dependent competing risks model with the distribution of one risk being a semiparametric proportional hazards model, whereas the model for the other risks and the degree of risk dependence of an Archimedean copula are unknown. Identifiability is shown when there is at least one covariate with at least two values. Estimation is done by means of a -consistent semiparametric two-step procedure. Applicability and attractive finite sample performance are demonstrated with the help of simulations. An application to unemployment duration confirms the importance of estimating rather than assuming risk dependence." (Author's abstract, IAB-Doku, © Elsevier) ((en))

    Löffler, Verena (2024): The Cost of Fair Pay: How Child Care Work Wages Affect Formal Child Care Hours, Informal Child Care Hours, and Employment Hours. (SOEPpapers on multidisciplinary panel data research at DIW Berlin 1205), Berlin, 81 S.

    Abstract

    "The debate on the effects of child care policies on household and individual behavior is substantial but lacks a discussion of the unintended consequences of rising wages in the child care work sector. To address this gap in the debate, the relation between rising pay and formal child care hours, informal child care hours, and employment hours is analyzed empirically with a case study on child care in Germany between 2012 and 2019. Among other findings, the evidence demonstrates that the consumption of formal child care hours of middle- and high-income households in eastern Germany correlates negatively with child care work wages, indicating price elasticity."

    Internal migration after a uniform minimum wage introduction (2024)

    Moog, Alexander (2024): Internal migration after a uniform minimum wage introduction. (arXiv papers 2404.19590), 47 S. DOI:10.48550/arXiv.2404.19590

    Abstract

    "Internal migration is an essential aspect to study labor mobility. I exploit the German statutory minimum wage introduction in 2015 to estimate its push and pull effects on internal migration using a 2% sample of administrative data. In a conditional fixed effects Poisson difference-in-differences framework with a continuous treatment, I find that the minimum wage introduction leads to an increase in the out-migration of low-skilled workers with migrant background by 25% with an increasing tendency over time from districts where a high share of workers are subject to the minimum wage (high-bite districts). In contrast the migration decision of native-born low-skilled workers is not affected by the policy. However, both native-born low-skilled workers and those with a migrant background do relocate across establishments, leaving high-bite districts as their workplace. In addition, I find an increase for unemployed individuals with a migrant background in out-migrating from high-bite districts. These results emphasize the importance of considering the effects on geographical labor mobility when implementing and analyzing policies that affect the determinants of internal migration."

    Mühlbauer, Sabrina & Enzo Weber (2024): Predicting Job Match Quality: A Machine Learning Approach. (IAB-Discussion Paper 09/2024), Nürnberg, 25 S. DOI:10.48720/IAB.DP.2409

    Abstract

    "Dieses Papier beschäftigt sich mit einer groß angelegten Datenanalyse um die Matching‑Qualität auf dem Arbeitsmarkt zu untersuchen. Hierfür verwenden wir einen sehr umfangreichen administrativen Datensatz zu Arbeitsmarktbiographien in Deutschland. Die Schätzungen werden sowohl mit maschinellem Lernen (extreme gradient boosting), als auch mit traditionellen statistischen Methoden (OLS, logit) durchgeführt. Bei der Gegenüberstellung beider Methoden wird deutlich, dass maschinelles Lernen insbesondere in den Bereichen Mustererkennung, Analyse von sehr großen Datensätzen und Minimierung der Fehlerrate deutliche Vorteile gegenüber den herkömmlichen Methoden aufweist. Schließlich werden die Prognosen für Matching‑Qualität (Stabilität und Löhne) mit Matching‑Wahrscheinlichkeiten kombiniert. Anhand dieser Ergebnisse wird für jede arbeitssuchende Person eine Liste mit Berufsvorschlägen generiert. Damit können Arbeitsvermittlern und Arbeitssuchenden Alternativen aufgezeigt werden, wodurch sich ihr Suchverhalten auf dem Arbeitsmarkt erweitern könnte." (Autorenreferat, IAB-Doku)

    Abstract

    "Establishment closures have lasting negative consequences for the workers they displace from their jobs. We study how these consequences vary with the amount of skill mismatch that workers experience after job displacement. Developing new measures of occupational skill redundancy and skill shortage, we analyze the work histories of individuals in Germany between 1975 and 2010. We estimate difference in-differences models, using a sample of displaced workers who are matched to statistically similar non-displaced workers. We find that displacements increase the probability of occupational change eleven-fold. Moreover, the magnitude of postdisplacement earnings losses strongly depends on the type of skill mismatch that workers experience in such job switches. Whereas skill shortages are associated with relatively quick returns to the counterfactual earnings trajectories that displaced workers would have experienced absent displacement, skill redundancy sets displaced workers on paths with permanently lower earnings. We show that these differences can be attributed to differences in mismatch after displacement, and not to intrinsic differences between workers making different post-displacement. career choices" (Author's abstract, IAB-Doku) ((en))

    Implications of Technology on Wages, Factor Shares and Inequalities across Demographic Groups in the European Labor Market (2024)

    Oleš, Tomáš (2024): Implications of Technology on Wages, Factor Shares and Inequalities across Demographic Groups in the European Labor Market. Bratislava, 134 S.

    Abstract

    "Acemoglu and Restrepo (2022) document that between 50% and 70% of changes in the U.S. wage structure over the last four decades are accounted for by relative wage declines of worker groups specialized in routine tasks in industries experiencing rapid automation. First, we draw major inspiration from this fact and provide new empirical evidence from France and Germany. Based on the evolution of real wages across the last four decades, especially in Germany, we observe strong support for the idea that high-skill biased technological change is displacing some of the least-educated workers. We utilize the conceptual framework by Acemoglu and Restrepo (2022), which links demographic group task displacement, productivity gains, and changes in wage and employment structures over the last three decades. We document that workers in groups more exposed to task displacement, particularly those with lower educational attainment, experienced larger declines in wages and employment (France being the exception), while those in less exposed groups enjoyed increases in wages and employment. We hypothesize that real wages do not reflect the task displacement experienced by workers in a similar way as documented in the U.S. because in France, and to a lesser extent in Germany, wages are downwardly rigid due to institutional factors and a different pace of adoption of automation technologies compared to the US. Second, we contribute to the scarce empirical literature by simultaneously examining the labor-complementing and labor-substituting effects of technology on employment changes, drawing inspiration from Autor et al. (2022). Using text analysis techniques, we create an objective measure of exposure to automation and augmentation for ISCO-08 occupations to robots, software and AI technology. We measure how semantically similar the inputs and outputs of an occupation are to the tasks embedded in the patent documents. Our findings reveal a moderate positive correlation between automation and augmentation exposure across occupations. We find that augmentation and automation move labor demand in countervailing directions. Specifically, we find that occupations with higher exposure to automation than to augmentation tend to experience, on average, declines in employment, while those with higher exposure to augmentation technologies see higher employment growth. These results are in line with the study by Autor et al. (2022). We also find that these findings are robust across different technologies (robots, software, and AI) and across manufacturing and non-manufacturing sectors. Third, we correlationally link labor productivity, wages, and the fall in aggregate labor share in France, Germany, Italy, and Spain with increasing market concentration. We find that as industry concentration increases, labor productivity and wages also increase, while labor share decreases. One of the much-discussed mechanisms behind this development is the spreading of fixed overhead labor costs over the larger value added by highly productive (superstar) firms (Autor et al., 2017), which, hand-in-hand, gain a larger market share. We follow the empirical approach of Stiel and Schiersch (2022) and test this prediction empirically using firm-level data from CompNet. Our findings show that labor share declines in a non-linear manner with increasing total factor productivity as we approach frontier (superstar) firms. Later, we link these observations with industry-level investment in digital technologies and explore the different effects on productivity, wages, and labor share across the firm size distribution. Our estimates indicate that increases in investment in digital capital or its deepening accelerate productivity and wages for firms operating in the fourth and fifth quintiles of the firm size distribution, but have zero impact on the labor share paid by firms."

    Wage inequality consequences of expanding public childcare (2024)

    Riedel, Lukas (2024): Wage inequality consequences of expanding public childcare. (ZEW discussion paper 24-006), Mannheim, 56 S.

    Abstract

    "This paper assesses the impact of a large expansion of public childcare in Germany on wage inequality. Exploiting regional variation in childcare supply over the 1990s, I show that in regions with stronger increases in childcare, wage inequality among women increased less strongly compared to regions with smaller increases. This is primarily driven by the lower half of the wage distribution and qualitatively similar for full- and part-time workers. Larger expansions in childcare, however, do not contribute to a further closing of the gender wage gap." (Author's abstract, IAB-Doku) ((en))

    Abstract

    "We investigate the wage assimilation of East Germans who migrated to West Germany after reunification (1990-1999). We compare their wage assimilation to that of ethnic German immigrants from Eastern Bloc countries and international immigrants to West Germany who arrived at the same time. The analysis uses administrative as well as survey data. The results suggest that East Germans faced significant initial earnings disadvantages in West Germany, even conditional on age and education. However, these disadvantages were smaller than those of international immigrants, supporting the beneficial role of cultural similarity. The earnings gap relative to West German natives narrowed over time for all immigrants. These findings are robust to controlling for potentially endogenous return migration and labor force participation. Controls for fixed effects reveal that positive assimilation for East German and international immigrants was concentrated among highly educated immigrants." (Author's abstract, IAB-Doku) ((en))

    Abstract

    "Earnings inequality in Germany has increased dramatically. Measuring inequality locally at the level of cities annually since 1985, we find that behind this development is the rapidly worsening inequality in the largest cities, driven by increasing earnings polarization. In the cross-section, local earnings inequality rises substantially in city size, and this city-size inequality penalty has increased steadily since 1985, reaching an elasticity of .2 in 2010. Inequality decompositions reveal that overall earnings inequality is almost fully explained by the within-locations component, which in turn is driven by the largest cities. The worsening inequality in the largest cities is amplified by their greater population weight. Examining the local earnings distributions directly reveals that this is due to increasing earnings polarization that is strongest in the largest places. Both upper and lower distributional tails become heavier over time, and are the heaviest in the largest cities. We establish these results using a large and spatially representative administrative data set, and address the top-coding problem in these data using a parametric distribution approach that outperforms standard imputations."

    Essays über Einkommensdynamiken und -risiken (2024)

    Schmal, Friederike (2024): Essays über Einkommensdynamiken und -risiken. 134 S.

    Abstract

    "Ziel dieser Arbeit ist es nun, einen Blick auf die Einkommensdynamiken im deutschen Arbeitsmarkt zu werfen, der einige Besonderheiten aufweist. Dazu gehören beispielsweise die deutsche Wiedervereinigung und die darauf folgenden Umstrukturierungen Anfang der 1990er Jahre oder auch die Globalisierung (Bartels (2014, S. 2)). Zunächst untersuche ich, welche Modellannahmen sich für die Einkommensmodellierung in Deutschland als tragfähig erweisen. Anschließend erfolgt die Einführung eines neuen Absicherungsinstrumentes, das auf Basis von Parametern zu Beginn des Erwerbslebens Assets kreiert, die gegen unerwartete Einkommensrisiken absichern sollen. Abschließend analysiere ich, inwieweit Ausbildungsentscheidungen das zukünftige Einkommen beeinflussen. Dies geschieht mittels der Schätzung kontrafaktischer Einkommenstrajektorien, die einen Vergleich zwischen den Entscheidungsfolgen ermöglichen. Bei all diesen Beiträgen spielen idiosynkratische Einkommensrisiken eine zentrale Rolle. Zur Untersuchung der zuvor genannten Fragestellungen werde ich zwei deutsche Datensätze heranziehen.2 Zum einen sind das Arbeitsmarktdaten von der Bundesagentur für Arbeit (Stichprobe der Integrierten Arbeitsmarktbiografien (SIAB)). Diese dienen zur Analyse der Einkommensmodellierung und -absicherung (Kapitel 2 und 3) und umfassen insgesamt Beobachtungen von mehr als 1.7 Millionen Individuen über einen Zeitraum von über 40 Jahren. Neben der Größe des Datensatzes ist besonders dessen Qualität hervorzuheben. Durch die administrative Aufbereitung und Bereitstellung sind beispielsweise vor allem die Einkommensobservationen besonders verlässlich. Das vierte Kapitel widmet sich der Schätzung kontrafaktischer Einkommensdynamiken in Abhängigkeit von bestimmten Ausbildungsentscheidungen im Leben eines Individuums. Um dabei auch kognitive Fähigkeiten berücksichtigen zu können, wechselt die Datengrundlage auf das Sozio-oekonomische Panel (SOEP). Auch dieser Datensatz ist mit fast 150 000 Individuen sehr umfangreich und umfasst mehrere Jahrzehnte (wie die SIAB-Daten). Im Gegensatz zu den vorher genutzten administrativen Daten werden in diesem Survey-Datensatz zahlreiche zusätzliche Variablen abgefragt (Schulnoten, selbst eingeschätzter Gesundheitszustand, Bildungshintergrund der Eltern). Allerdings bringen Survey-Daten auch einige Nachteile mit sich. Laut Guvenen, Pistaferri u. a. (2022) gehören dazu unter anderem Probleme mit Messfehlern, eine mangelnde Repräsentativität (insbesondere an den Rändern der Verteilungen), das Ausscheiden von Individuen (sample attrition) und eine kleine Stichprobengröße. In dieser Arbeit wird durch die mehrmalige Ausführung von Datenreinigungs- und Imputationsschritten bei den zwei genutzten Datensätzen jeweils eine hohe Datenqualität erzielt."

    Abstract

    "The Bologna Process reformed the German university system by introducing three-year undergraduate degrees. We evaluate the effects on the dual apprenticeship system where 29% of new apprentices are also qualified for university. For identification, we exploit regional and temporal variation in reform adoption, using administrative student and labor market data from 1997 to 2015. The Bologna reform implementation reduced the number of new highly educated apprentices considerably. In particular, clerical apprenticeships were affected. Firms did not substitute with less-educated apprentices, but partly replaced the lower supply of new highly educated apprentices with university graduates in the long run."

    Abstract

    "We analyze how skill transferability and the local industry mix affect the adjustment costs of workers hit by a trade shock. Using German administrative data and novel measures of economic distance we construct an index of labor market absorptiveness that captures the degree to which workers from a particular industry are able to reallocate into other jobs. Among manufacturing workers, we find that the earnings loss associated with increased import exposure is much higher for those who live in the least absorptive regions. We conclude that the local industry composition plays an important role in the adjustment processes of workers." (Author's abstract, IAB-Doku) ((en))
