Abstract

"Die Lage am Ausbildungsmarkt ist angespannt: Viele Unternehmen können ihre Ausbildungsplätze nicht besetzen, während gleichzeitig zahlreiche Jugendliche ohne Ausbildungsplatz bleiben. Um diese Passungsprobleme zu überwinden, ist es wichtig, dass Unternehmen ihre Ausbildungsplätze dort bewerben, wo Jugendliche suchen. Besonders wichtig sind für Jugendliche Online-Stellenanzeigen und die Vermittlungsangebote der Bundesagentur für Arbeit. An dritter Stelle stehen Social-Media-Kanäle. Die passgenaue Auswahl von Social-Media-Kanälen und -Inhalten kann Unternehmen somit näher an Jugendliche bringen. Doch: Während Jugendliche vor allem über Instagram, YouTube und WhatsApp suchen, nutzen Unternehmen neben Instagram eher Facebook, LinkedIn und Xing. Gerade Facebook ist für Jugendliche jedoch kaum relevant. Die direkte Ansprache von Jugendlichen mit Haupt- und Realschulabschluss bietet besonders großes Potenzial, denn es zeigt sich, dass Haupt- und Realschüler:innen anders suchen als Abiturient:innen: Haupt- und Realschüler:innen nutzen neben Online-Stellenanzeigen besonders analoge Formate. In den sozialen Medien nutzen sie vorwiegend Instagram, WhatsApp und YouTube." (Autorenreferat, IAB-Doku)

Abstract

"Overeducated workers are more productive and have higher wages in comparison to their adequately educated coworkers in the same jobs. However, they have lower wages than their similarly educated peers who are in correctly matched jobs. This study examines the hypotheses that overeducated workers sort into performance pay jobs as an adjustment mechanism and that performance pay enhances their wages. Using the SOEP, I show that overeducation associates with a higher likelihood of sorting into performance pay jobs and that performance pay significantly improves the wages of overeducated workers. The findings hold in endogenous switching regressions and several robustness checks." (Author's abstract, IAB-Doku) ((en))

Abstract

"Using a weekly survey of unemployed workers, this study examines gender differences in reservation wages and applied-for occupational categories. The analysis shows that a large portion of the gender difference in reservation wages is attributable to the fact that women and men search for different occupations. Findings further demonstrate that women are more likely to apply to occupations with higher percentages of female incumbents, and they target these occupations from the earlier stages of their job search, rather than adjusting their preferences over the course of unemployment. Further analysis shows that women are more likely to apply for occupational categories that offer greater flexibility in working hours, more opportunities for interpersonal interactions, less critical decision-making, and a less competitive environment. Finally, the analysis reveals that household responsibilities, particularly the number of children, and willingness to take risks are important factors influencing women’s decisions to pursue occupations with less demanding work hours."

Benanav, Aaron (2025): When an Accountant Becomes a Taxi Driver: Unemployment, Labor Market Institutions, and Economic Theory. In: History of political economy. DOI:10.1215/00182702-12134470

Abstract

"This article reconstructs the history of how economists came to understand unemployment as a distinct category and how that understanding transformed over time. In the early twentieth century, governments regulated access to unemployment benefits and established labor market protections, drawing sharper boundaries between employment and unemployment. Historians have shown that these boundaries were politically constructed, but economic theory largely treated them as given. Postwar Keynesian models assumed that unemployment was a temporary and measurable condition between spells of stable, high-wage work. However, that assumption rested on a historically specific labor market structure that began to unravel in the 1970s and 1980s. As stable jobs contracted, more workers cycled through precarious employment rather than remaining fully unemployed or finding new stable work. Economic theory responded with new models focused on individual incentives and firm behavior, but these also tended to treat emerging patterns as evidence of how unemployment had always functioned, rather than as signs of a shifting institutional landscape. By tracing how the category of unemployment was constructed and transformed—and how economists responded to those shifts—this article shows how changes in institutional context shape the development of economic thought itself."

Abstract

"Job applications have risen over time, yet job-finding rates remain unchanged. Meanwhile, separations have declined. We argue that increased applications raise the probability of a good match rather than the probability of job-finding. Using a search model with multiple applications and costly information, we show that when applications increase, firms invest in identifying good matches, reducing separations. Concurrently, increased congestion and selectivity over which offer to accept temper increases in job-finding rates. Our framework contains testable implications for changes in offers, acceptances, reservation wages, applicants per vacancy, and tenure, objects that enable it to generate the trends in unemployment flows."

Abstract

"Whether firms founded during or outside economic crises have greater growth potential is an important question for both prospective entrepreneurs and policy makers. Existing research offers conflicting answers, and mostly either focuses on aggregate cohort-level effects or selectively excludes small new firms from the analyses. Using extensive linked employer-employee data on young German firms around and during the Global Financial Crisis, a period of sharply reduced access to external capital and recession, we show that young firms respond to cyclical conditions in highly heterogeneous ways. Our firm-level results reveal that the average new firm found it easier to hire its first employees when it was founded during the crisis. These firms achieved countercyclical growth by hiring career entrants. More specifically, hiring in very young (<1.5 years) and small to medium-sized (below the 90th percentile) young firms was countercyclical, while this was not the case for older and larger young firms. Thus, the firm-specific effects for young entrepreneurial firms may be very different from those reported in previous research. Our results suggest that market entry during a crisis may facilitate hiring and that policies that promote entrepreneurship may usefully complement policies that encourage labor hoarding by incumbents during recessions."

Abstract

"Workers’ job mobility decisions are related to firms’ wage policies but also depend on tax schedules. Using Norwegian population-wide administrative linked employer-employee data for 2010–2019, we study how the job-to-job turnover of employees is affected by marginal taxes and firms’ pay policies, thus drawing inferences on job search behaviour. By paying higher wages, job-to-job separation rates drop, but this negative relationship is weakened when income taxes increase, consistent with higher taxes reducing search activity. However, consistent with theory, the tax effect is smaller where workers receive performance bonuses." (Author's abstract, IAB-Doku, © 2025 The Author(s). Published by Elsevier B.V.) ((en))

Börschlein, Erik-Benjamin (2025): Essays on Wages and Minimum Wages in Frictional Labor Markets. 237 S. DOI:10.5283/epub.76880

Abstract

"In Deutschland ist das Zusammenspiel zwischen Löhnen und institutionellen sowie marktbedingten Friktionen ein zentrales Thema wirtschaftspolitischer Debatten. Diese Dissertation untersucht in drei empirischen Studien kausale Zusammenhänge zwischen Löhnen und Mindestlöhnen, Matchingfriktionen und Arbeitsmarktanspannung. Die Analysen basieren auf umfangreichen administrativen Daten der Bundesagentur für Arbeit und nutzen fortgeschrittene ökonometrische Methoden zur kausalen Inferenz. Die ersten beiden Kapitel betrachten institutionelle Effekte – insbesondere die Einführung des gesetzlichen Mindestlohns im Jahr 2015 – während das dritte Kapitel den Fokus auf veränderte Marktbedingungen legt, insbesondere den zunehmenden Fachkräftemangel. Ziel ist es, die Wirkungsmechanismen zwischen Löhnen und Arbeitsmarktfriktionen differenziert darzustellen. Kapitel 1 Dieses Kapitel entwickelt einen innovativen Machine-Learning-Ansatz zur verbesserten Schätzung langfristiger Lohneffekte des Mindestlohns. Übliche Studien basieren auf einem fixen Pre-Treatment-Indikator („Bite“), basierend auf Löhnen vor der Politikmaßnahme, der die Betroffenheit von der Mindestlohneinführung nur kurzfristig akkurat abbildet. Um langfristige dynamische Veränderungen zu erfassen, werden hier ein zeitvariable Bite-Indikatoren mittels LASSO-basierter Vorhersagemodelle konstruiert, welche die Inzidenz und die Intensität der Mindestlohnbetroffenheit abbilden. Basierend auf administrativen Daten der Jahre 2010–2014 wird die Mindestlohnbetroffenheit für den Zeitraum 2015–2020 vorhergesagt. In der anschließenden Differenz-von-Differenzen-Analyse zeigen sich signifikant positive Lohneffekte, die im Vergleich zu herkömmlichen Methoden jedoch geringer ausfallen und über die Zeit konstant bleiben. Die Ergebnisse deuten darauf hin, dass traditionelle Evaluierungen die Effekte überschätzen könnten, da sie dynamische Selektionseffekte und mindestlohnunabhängige Lohnentwicklungen nicht ausreichend berücksichtigen. Kapitel 2 In diesem Kapitel wird untersucht, wie sich die Einführung des Mindestlohns auf offene Stellen und damit verbundene Friktionen im Matching-Prozess ausgewirkt hat. Die Analyse basiert auf administrativen Vakanzdaten und Erwerbsbiographien. Die Analyse erfolgt auf der Berufsebenen für den Zeitraum 2013–2019 und nutzt ein Differenz-von-Differenzen-Design. Die Ergebnisse zeigen, dass die Anzahl neu gemeldeter Stellen durch die Mindestlohneinführung insgesamt nicht zurückging. Jedoch stieg der Anteil stornierter Vakanzen um 4–9 Prozent, und die Dauer erfolgreicher Besetzungsprozesse erhöhte sich um 5–6 Prozent. Dies deutet auf verstärkte Such- und Matchingfriktionen hin, etwa durch höhere Einstellungsstandards oder reduzierte berufliche Mobilität. Ergänzende Analysen zeigen geringere Übergänge zwischen Arbeitgebern, insbesondere bei Berufswechseln. Somit wird deutlich, dass die Mindestlohneinführung zwar nur geringe Auswirkungen auf die Beschäftigung hatte, aber dennoch Matchingprozesse erheblich beeinflusst hat. Kapitel 3 Dieses Kapitel wechselt die Perspektive und untersucht, wie zunehmende Arbeitsmarktanspannung – gemessen als Verhältnis von offenen Stellen zu Arbeitssuchenden – die Lohnentwicklung beeinflusst hat. Mithilfe eines Leave-One-Out-Instruments wird der kausale Effekt lokaler Arbeitsmarktanspannung in beruflichen Arbeitsmärkten auf Löhne geschätzt. Die Ergebnisse zeigen moderate, aber signifikant positive Lohneffekte, die etwa 7–19 Prozent des realen Lohnwachstums in Deutschland zwischen 2012 und 2022 erklären. Besonders stark profitieren neu Eingestellte, Hochqualifizierte, Beschäftigte im Dienstleistungssektor und Arbeitnehmer in Ostdeutschland. Zudem steigt der Lohn in Niedriglohnunternehmen überdurchschnittlich stark, was auf eine Verringerung der Lohnungleichheit hindeutet. Im Gesamtfazit werden die Erkenntnisse der drei Studien zusammengeführt. Die Arbeit zeigt, wie institutionelle Eingriffe wie der Mindestlohn einerseits Löhne anheben, gleichzeitig aber neue Friktionen erzeugen können. Andererseits können veränderte Marktbedingungen auch ohne staatliche Eingriffe Löhne steigern – wie etwa bei hoher Arbeitsmarktanspannung. Methodisch hebt die Dissertation die Bedeutung administrativer Mikrodaten und robuster kausaler Analyseverfahren in der Arbeitsmarktforschung hervor." (Autorenreferat, IAB-Doku)

Abstract

"We examine how search frictions impact labor market sorting by constructing a model consistent with evidence that employers interview a subset of a pool of applicants. We derive necessary and sufficient conditions for sorting in applications and matches. Positive sorting is obtained when production complementarities outweigh a counterforce measured by a (novel) quality-quantity elasticity. Interestingly, the threshold for the complementarities depends on the fraction of high-type workers and can be increasing in the number of interviews. Our model shows how policies like Ban the Box can backfire because when screening workers becomes harder, firms may discourage certain workers from applying." (Author's abstract, IAB-Doku) ((en))

Abstract

"Ob und wie Arbeitnehmer am Arbeitsplatz suchen, hängt von ihren Vorstellungen über die Bezahlung und die Arbeitsbedingungen in anderen Unternehmen ab. Dennoch ist wenig darüber bekannt, wie viel Arbeitnehmer tatsächlich über die Arbeitsentgelte außerhalb ihrer aktuellen Beschäftigung Bescheid wissen. Wir nutzen eine groß angelegte Umfrage unter deutschen Vollzeitbeschäftigten, welche mit Sozialversicherungsdaten verknüpft wurde, um Gehaltserwartungen und Präferenzen gegenüber bestimmten externen Unternehmen zu ermitteln. Arbeitnehmer glauben, dass sie mit erheblicher Heterogenität hinsichtlich der Vergütung bei anderen Unternehmen konfrontiert sind und richten ihre Suche nach einem neuen Arbeitsplatz auf Unternehmen aus, von denen sie ausgehen, dass diese mehr bezahlen. Die von den Arbeitnehmern erwarteten unternehmensspezifischen Lohnaufschläge korrelieren sowohl stark mit den Vergütungsschemata, die sich anhand von administrativen Daten zeigen, als auch mit der Würdigung von firmenspezifischer Annehmlichkeiten. Die meisten Arbeiter sind auch bei einer erheblichen Erhöhung des Gehalts nicht bereit, sich einen neuen Job zu suchen – oder ihr derzeitiges Unternehmen zu verlassen. Die Kosten eines Jobwechsel betragen zwischen 7 und 18 Prozent des Jahreslohns eines Arbeitnehmers. Die Zugehörigkeit zu einem Arbeitgeber variiert je nach Arbeitgeber und kann nicht anhand von Unterschieden in firmenspezifischen Annehmlichkeiten oder den Kosten des Jobwechsels erklärt werden."

Abstract

"This paper explores the role of employment pool composition on labor matching effectiveness in ten Central and Eastern European countries from 2005 to 2023. We control for the structure of the labor force in terms of education, age, and gender. The results point towards a significant impact of labor force structure on labor market outcomes. In particular, an improvement in labor matching is associated with a larger share of the labor force with advanced education. In contrast, the opposite is true for the share of women and younger persons in the labor force. The results are robust to different specifications of the model when we control for the role of institutional factors in regulating national labor markets. From a policy perspective, this study highlights the need for targeted policies to increase the efficiency of the matching process aimed at specific structures of the labor force."

Abstract

"Better skills matching has long been proposed as one of the key advantages of agglomeration economies. Yet, support for this improved matching has remained largely founded upon indirect proxies for skills such as wages and education. This paper contributes to the literature by offering novel empirical evidence on the relationship between specific measures of localised skills deficiencies and agglomeration economies, in the form of industrial density. Developing an instrumental variable approach and controlling for unobserved heterogeneity and other region-industry idiosyncratic effects across a panel dataset for the period 2009–2019 in England and Wales, our analysis reveals a positive effect of agglomeration economies in reducing both skills gaps within the employed workforce and skills shortages in the labour market external to the firm. We consider these findings in the context of persistent regional imbalances and the importance of strengthening skills provision within current regional industrial strategies."

Abstract

"How does being over- or underqualified at the beginning of a worker's career affect skill acquisition, retention, and promotion? Despite the importance of mismatch for the labor market, self-selection into jobs has made estimating these effects difficult. We overcome endogeneity concerns in the context of the US Air Force, which allocates new enlistees to over 130 different jobs based, in part, on test scores. Using these test scores, we create simulated job assignments based on factors outside of an individual's control: the available slots in upcoming training programs and the quality of other recruits entering at the same time. These factors create quasi-random variation in job assignment and hence how cognitively demanding an individual's job is relative to their own ability. We find that being overqualified for a job causes higher attrition, both during technical training and afterward when individuals are working in their assigned jobs. It also results in more behavioral problems, worse performance evaluations, and lower scores on general knowledge tests about the military taken by all workers. On the other hand, overqualification results in better performance relative to others in the same job: job-specific test scores rise both during technical training and while on the job, and these individuals are more likely to be promoted. Combined, these patterns suggest that overqualified individuals are less motivated, but still outperform others in their same job. Underqualification results in a polar opposite set of findings, suggesting these individuals are motivated to put forth more effort, but still struggle to compete when judged relative to others. Consistent with differential incentives, individuals who are overqualified are in jobs which are less valuable in terms of outside earnings potential, while the reverse is true for those who are underqualified."

Abstract

"We investigate employer recruiting behaviour, using detailed firm-level data from a national survey of employers hiring recent college graduates. We find this behaviour is responsive to the business cycle, beliefs about labour market tightness, and the intended number of hires. Specifically, employers adjust planned recruiting effort and compensation. We then show that when firms expend greater recruiting effort they ultimately hire more individuals per vacancy. These results suggest that when firms want to increase hires they adjust both the quantity of vacancies and the recruiting intensity per vacancy. If this is true more broadly in the labour market, it may help explain the breakdown in the standard matching function during the Great Recession." (Author's abstract, IAB-Doku) ((en))

Abstract

"We show the causal influence of the launch of generative artificial intelligence (AI) in the form of ChatGPT on the search behavior of young people for apprenticeship vacancies. To estimate the short- and medium-term effects, we use a variety of methods, including a difference-in-discontinuity approach exploiting the exogenous nature of the unanticipated launch of ChatGPT in 2022. There is a strong short- and medium-term decline in the intensity of searches for vacancies, indicating a notable reduction in the supply of young people actively seeking apprenticeships and suggesting great uncertainty among the affected cohort. Occupations with a high proportion of cognitive tasks and with high demands on language skills were particularly affected by the decline. Interestingly, the revealed preferences in the search behavior of young job seekers contrasted with previous expert assessments on the automation risks of occupations and aligned with the most recent assessments of the AI and language model exposure of occupations – before these new assessments existed. Notably, while the supply decline did not reduce the number of signed apprenticeship contracts, we find evidence of declining applicant quality, particularly for commercial employees, the most widely offered apprenticeship in Switzerland."

Abstract

"This paper estimates the wage offer distribution using workers who received multiple offers in a short period of time, including both accepted and rejected offers. We show that, after accounting for worker heterogeneity and measurement error, each wage offer is a random draw from the same distribution, and a normal distribution with a standard deviation of 0.137 is consistent with data. The dispersion is smaller than most estimates in the literature, increasing in the unemployment rate for workers without a bachelor’s degree, but not significantly related to a worker’s age or employment status."

Kline, Patrick (2025): Labor Market Monopsony: Fundamentals and Frontiers. (RF Berlin - CReAM Discussion Paper Series 2025,36), Berlin, 82 S.

Abstract

"This chapter reviews the theory of monopsonistic wage setting, its empirical implications, and some puzzles the framework has struggled to explain. We begin by examining the fundamentals of monopsonistic wage determination. The core of the theory is a mapping from the distribution of worker outside options to wages. We study non-parametric shape restrictions that ensure this mapping is unique. Building on these results, we introduce a menu of tractable parametrizations of labor supply to the firm, some of which are shown to emerge naturally from equilibrium search models. Next, we review why wage markdowns do not necessarily signal inefficiency and discuss some criteria for assessing misallocation in a monopsony model with search frictions. Turning to the model’s empirical implications, we examine how the magnitude of productivity-wage passthrough depends on the super-elasticity of labor supply to the firm and establish that compensating differentials for firm amenities depend on the curvature of the outside option distribution. We show that firm-specific shifts in either productivity or amenities can be used as instruments to identify labor supply elasticities and review strategies for estimating non-constant elasticities. We then consider extensions of the basic model involving third-degree wage discrimination and examine their ability to rationalize patterns of worker-firm sorting. Monopsony models traditionally assume that firms commit to posted wages. Relaxing this assumption, we develop a connection between the first-order conditions of the monopsony model and models of bargaining with incomplete information. These models explain why bilateral inefficiencies may persist in the presence of negotiation, yield predictions about the response of within-firm wage dispersion to productivity shocks, and suggest reasons why some productivity shifters may not constitute excludable instruments. Next, we endogenize productivity by allowing for efficiency wages, non-constant returns to scale, and price-cost markups. Empirical monopsony estimates often suggest that firms enjoy implausibly large profit margins. We argue that allowing for non-constant labor supply elasticities and firm adjustment costs can potentially resolve this difficulty. Finally, we review why the strong passthrough of minimum wages to product prices presents a challenging puzzle for standard monopsony models and discuss potential reconciliations to this puzzle involving firm heterogeneity, quality upgrading, and lumpy price adjustment."

Abstract

"This paper develops an equilibrium model of the labor market that incorporates hours worked, off- and on-the-job search, and both single and multiple jobholders. Central to the model’s mechanism is that taking on a second job ties the worker to her primary employer, while simultaneously providing the worker with a stronger outside option when bargaining with the secondary employer. The model quantitatively accounts for both the incidence of multiple jobholding and worker flows in and out of second jobs. It also sheds light on how multiple jobholding shapes outcomes that are typically the focus of search models. Multiple jobholding has opposing effects on job-to-job transitions, which largely offset each other. At the same time, the option of holding second jobs extends the survival of a worker’s main job, thereby reducing job separations and increasing the employment rate. These findings have significant implications for calibrating standard search models that ignore multiple jobholding." (Author's abstract, IAB-Doku) ((en))

Abstract

"This paper examines how gender-specific application behaviour, firms’ hiring practices, and flexibility demands relate to the gender earnings gap, using linked data from the German Job Vacancy Survey and administrative records. Women are less likely than men to apply to high-wage firms with high flexibility requirements, although their hiring chances are similar when they do. We show that compensating differentials for firms’ flexibility demands help explain the residual gender earnings gap. Among women, mothers experience the largest earnings penalties relative to men in jobs with high flexibility requirements." (Author's abstract, IAB-Doku) ((en))

Abstract

"Although the Diamond-Mortensen-Pissarides (DMP) model originated roughly 40 years ago and its authors shared the 2010 Nobel Memorial Prize in Economic Sciences, their work is still absent from several recent editions of popular intermediate macroeconomics textbooks. In contrast, Stephen Williamson's textbook (2014, 2018) presents an early static version of the DMP model accessible to undergraduates. This article's author compensates for the topic's omission in some intermediate-level textbooks by discussing Williamson's static DMP model and presenting four additional exercises not covered in his main text: (1) a change in a vacancy's posting price; (2) an increase in workers' relative bargaining power; (3) the introduction of a minimum wage; and (4) the introduction of an endogenous unemployment insurance benefit. The latter exercise yields an interesting neutrality result." (Author's abstract, IAB-Doku) ((en))

Abstract

"This paper takes the canonical Burdett-Mortensen model of wage-posting and relaxes the assumption that wages are set once-for-all, instead assuming they can only be committed one period at a time. It derives a closed-form solution for a steady-state Markov Rank-Preserving Equilibrium and shows how this relates to the canonical model and performs some comparative statics on it. But it is shown that a Rank-Preserving Equilibrium may fail to exist because employers have more monopsony power over existing workers than new recruits and that this non-existence can be a problem for plausible parameter values. It is shown how a Rank-Inverting Equilibrium may exist. It is argued that this problem is likely to occur in a wide range of search models." (Author's abstract, IAB-Doku) ((en))

Abstract

"The paper establishes a new link between fiscal tightening and the vertical skills mismatch rate, defined as the share of over-qualified workers. Using cross-country evidence for Europe, we show that fiscal tightening can increase skills mismatch. We then introduce the latter in a DSGE model with heterogeneous households, capital-skill complementarity (CSC) and labor frictions. We calibrate the model for Greece, where the over-qualification rate exceeds one-third. A fiscal tightening shock raises the mismatch rate in the model, in line also with SVAR analysis. Skills mismatch can act as a buffer for high-skilled workers during recessions induced by tax shocks and is more counter-cyclical when CSC is weak. We also use the model to conduct welfare and policy analyses." (Author's abstract, IAB-Doku, © 2025 Elsevier B.V.

Abstract

"Vor dem Hintergrund aktueller Reformüberlegungen zur Zumutbarkeit von Arbeit nach § 10 SGB II untersucht dieser Forschungsbericht, welche Entfernungen zwischen Wohnort und Arbeitsort bei Beschäftigungsaufnahmen von Personen im Grundsicherungsbezug typischerweise auftreten. Im Fokus stehen dabei systematische Unterschiede nach Personengruppen. Grundlage der Analysen sind administrative Daten aus den Integrierten Erwerbsbiografien (IEB) und der Leistungshistorik Grundsicherung (LHG) für das Jahr 2022. Untersucht werden erwerbsfähige Leistungsberechtigte im SGB II, die aus dem Grundsicherungsbezug heraus eine sozialversicherungspflichtige Beschäftigung aufgenommen haben. Ergänzend werden Befragungsdaten aus der ersten Welle des Online-Panel for Labour Market Research (OPAL) des IAB verwendet, um das beobachtete Verhalten mit den Selbstangaben von Grundsicherungsbeziehenden zu ihrem Arbeitssuchverhalten abzugleichen. Die Mehrheit nimmt eine Beschäftigung in Wohnortnähe auf. In 69 Prozent der Fälle liegt der Arbeitsort weniger als 15 km entfernt, in 17 Prozent zwischen 15 und 50 km. Gleichzeitig nimmt ein nicht unerheblicher Anteil auch größere Distanzen in Kauf: In 8,7 % der Fälle liegt der neue Arbeitsort mehr als 100 km vom bisherigen Wohnort entfernt. Die durchschnittliche Entfernung variiert deutlich zwischen unterschiedlichen Personengruppen. Alleinerziehende, Eltern minderjähriger Kinder, Ältere sowie Personen mit gesundheitlichen Einschränkungen nehmen im Mittel kürzere Distanzen in Kauf. Auch Teilzeitbeschäftigte verbleiben häufiger in der Nähe ihres bisherigen Wohnorts. Umgekehrt nehmen junge, alleinstehende oder hochqualifizierte Personen im Mittel Arbeitsstellen in durchschnittlich größerer Entfernung an. Ähnliche Unterschiede zeigen sich auch bei der Wahrscheinlichkeit, eine Beschäftigung in mehr als 100 km Entfernung aufzunehmen. Die meisten dürften dafür umziehen. Die Analysen basieren auf multivariaten Regressionsmodellen, die eine Vielzahl potenziell relevanter Merkmale kontrollieren. Die Unterschiede zwischen den Gruppen bleiben auch nach Kontrolle dieser Merkmale bestehen und decken sich mit den Ausnahmeregelungen des § 10 Abs. 2 SGB II. Diese sehen vor, dass bei der Prüfung der Zumutbarkeit persönliche, familiäre und gesundheitliche Gründe zu berücksichtigen sind. Die OPAL-Befragungsdaten bestätigen diese Befunde tendenziell. So zeigen sich ähnliche gruppenspezifische Muster bei der Selbsteinschätzung zur Bereitschaft, längere Pendelzeiten oder einen Umzug in Kauf zu nehmen. Frauen, ältere Personen, Alleinerziehende und Personen, die eine Teilzeitbeschäftigung suchen, geben seltener an, für eine Stelle über 60 Minuten pendeln oder umziehen zu wollen. Gleichzeitig zeigen Personen mit Hochschulabschluss sowie ausländischer Staatsangehörigkeit eine höhere Bereitschaft zu räumlicher Mobilität. Die in den administrativen Daten erkennbaren Unterschiede in den Entfernungen zwischen Wohn- und Arbeitsort lassen sich also durch Unterschiede im Arbeitssuchverhalten plausibel erklären. Diese Befunde lassen sich weniger als Folge der aktuellen gesetzlichen Ausnahmeregelungen interpretieren, sondern vielmehr als deren empirische Grundlage: Denn § 10 SGB II trägt den gruppenspezifisch variierenden Mobilitätsmöglichkeiten Rechnung. Die Ausnahmetatbestände in § 10 SGB II wurden eben gerade deshalb geschaffen, weil Alleinerziehende und andere räumlich weniger mobile Personen seltener weite Pendelwege oder einen Umzug in Kauf nehmen können oder wollen. Es erscheint daher sinnvoll, bestehende Mobilitätshemmnisse gezielt abzubauen, die Bereitschaft zu überregionaler Mobilität bei der Vermittlung zu berücksichtigen und so individuelle Vermittlungsstrategien zu stärken. Zudem sollte die Politik die institutionellen Rahmenbedingungen – etwa Möglichkeiten zur Kinderbetreuung, den Wohnungsmarkt, und die Verkehrssituation – in den Blick nehmen, um die Mobilitätsbereitschaft zu erhöhen."

Abstract

"Word-of-mouth for employers (WOME; i.e., employees talking positively about their employer organization) is a valuable corporate means of recruitment in times of employee shortage and war for talent. However, research on the determinants of WOME is fragmented, and the identification of success factors is incomplete. Based on research on word-of-mouth mechanisms and social exchange theory, which explains exchange relationships between sender and receiver, we elaborate on a model of WOME that comprises classic and emerging factors of workplace attractiveness (monetary compensation, work environment, and workplace fun) and internal corporate social responsibility (ICSR). We hypothesize that ICSR exhibits the greatest explanatory power for WOME. We tested our assumption with a data set of 132,995 participants from 13 industrial sectors in Germany and ran a multiple linear regression analysis with four independent variables and WOME as the dependent variable. ICSR proved to have the greatest effect on WOME, which we consider a result of employees’ interest in a fair exchange relationship with their employers, followed by workplace fun, the work environment, and monetary compensation. We discuss the results in terms of the above-mentioned theories and point out directions for future research as well as practical implications." (Author's abstract, IAB-Doku) ((en))

Nichols, Bethany J., David S. Pedulla & Jeff T. Sheng (2025): More Than a Match: “Fit” as a Tool in Hiring Decisions. In: Work and occupations, Jg. 52, H. 2, S. 175-203. DOI:10.1177/07308884231214279

Abstract

"The concept of “fit” has become important for understanding hiring decisions and labor market outcomes. While social scientists have explored how fit functions as a legitimized evaluative criterion to match candidates to jobs in the hiring process, less is known about how fit functions as a hiring tool to aid in decision-making when hiring decisions cannot—or should not—be justified. Drawing on in-depth interviews with 53 hiring professionals, we develop a theoretical argument that hiring professionals can use fit as a tool to circumvent legitimized hiring criteria and justify their hiring goals. Specifically, we show how hiring professionals use fit as a tool to explain their hiring decisions when these decisions cannot or should not be justified and we outline two mechanisms through which this process occurs: (1) fit as a tool for circumventing human capital concerns, and (2) fit as a tool to circumvent hiring policies based upon social characteristics. We argue that fit is more than an evaluative criterion for matching individuals to jobs. Hiring professionals deploy fit as a tool to justify their decisions amid uncertainty and constraint. Fit, then, becomes a placeholder when these hiring decisions are not able to be justified through legitimized means. Our findings reveal some of the potential negative consequences of using fit during the hiring process and contribute important theoretical insights about the role of fit in scholarship on inequality and labor markets."

Platonov, Konstantin (2025): Post-pandemic recovery: Search and matching, market power, and endogenous labor demand. In: Economic Modelling, Jg. 151. DOI:10.1016/j.econmod.2025.107183

Abstract

"Following the COVID-19 pandemic, United States (US) output rebounded quickly, labor productivity rose above pre-pandemic levels, profit rates increased, and the labor market tightened, all despite high unemployment. These observations can be reconciled in a search and matching model of the labor market with two new assumptions of strong firm market power and endogenous labor demand. Market power encourages firm entry when prices rise, while endogenous labor demand enables firms to adapt to shocks rather than shut down. Two regimes arise: one with weak market power, representing the pre-pandemic era and another with strong market power, explaining the post-pandemic recovery. Under strong market power, firm entry drives recovery following recessions, the labor market becomes tight, wages and producer prices rise, and the average firm size shrinks, which is consistent with the post-pandemic data. This study demonstrates how a typical business cycle can be reconciled with US post-pandemic recovery within a unified model, highlighting the non-trivial role of firms’ market power in shaping macroeconomic outcomes."

Porter, Caitlin M., Pol Solanelles, Kristin L. Cullen‐Lester, Ashley Howell Pearson & Juan Du (2025): A Tale of Two Job Searches: An Integrative Review of How Job Seeker Characteristics Shape Informal Job Search Effectiveness. In: Journal of organizational behavior, S. 1-25. DOI:10.1002/job.2864

Abstract

"Informal job search—the use of personal and professional networks for job search—is a popular job search method. Yet, answers to the questions of whether informal job search is effective (relative to formal job search) and why have not been clearly articulated, hindering research progress and limiting practical recommendations for job seekers and institutions. We endeavored to address these questions via an integrative, interdisciplinary review of how job search methods (i.e., formal vs. informal) and forms of social capital (i.e., types of contacts and tie strength) relate to job search outcomes (i.e., finding a job vs. finding quality employment), and we summarize evidence for the role of job seeker characteristics as key contingencies on this process. In doing so, we uncover “a tale of two job searches,” wherein informal job search effectiveness is dependent upon job seeker characteristics that impart status within the labor market and/or society. Collectively, our review provides much-needed clarity regarding whether an informal job search is better than a formal job search and why , revealing that answers to these questions depend on who is searching for a job. Considering these insights, we outline an agenda for future research focused on enhancing job seekers' access to social networks and integrating job search and social network perspectives to extend knowledge of how different types of job seekers can more effectively utilize their networks for job search."

Rendon, Silvio (2025): Testing for wage-specific search intensity. In: Journal for labour market research, Jg. 59, H. 1. DOI:10.1186/s12651-024-00389-4

Abstract

"Most job search intensity models assume uniform search effort across all potential wage offers. I depart from this conventional assumption by proposing that agents allocate wage-specific search intensity, strategically avoiding effort on low-paying, unacceptable jobs or high-paying, improbable ones. This alternative model generates wage distributions at acceptance that differ markedly from the truncated distributions typical of models with constant arrival rates for wage offers. I leverage these distinct empirical predictions to develop two new nonparametric tests, applied to NLSY97 data, both of which reject the hypothesis of constant search intensity across wages. Furthermore, I estimate the structural parameters identifiable in each model, revealing that wage-specific search leads to greater total search effort, faster transitions into the upper tail of the wage distribution, and ultimately higher accepted wages—more than a 25% increase following unemployment. For low wages, the classic random search model delivers a fair replication of the actual data, but for higher wages targeted search is better. Wage-specific search suggests that job seekers not only need to search more, but also search better. This insight has important implications for employment policy, particularly in promoting job search literacy among the unemployed." (Author's abstract, IAB-Doku) ((en))

Abstract

"Anonymisierte Bewerbungsverfahren sind potenziell geeignet, Einstellungshindernisse aufgrund von Diskriminierung einzelner Arbeitsmarktgruppen abzubauen. Bei effektiver Umsetzung sorgen solche Verfahren für Chancengleichheit im Bewerbungsprozess, da sie den Fokus der Personalentscheider auf die Qualifikationen und Fähigkeiten der Bewerber lenken.

Sielschott, Stephan, Oliver Lauxen & Christa Larsen (2025): Betriebliche Ausbildung. IAB-Betriebspanel Report Hessen 2024. (IAB-Betriebspanel Hessen 2/2024), Frankfurt am Main, 24 S.

Abstract

"In den kommenden Jahren gehen in Deutschland und in Hessen viele Arbeitnehmerinnen und Arbeitnehmer aus den geburtenstarken Jahrgängen in den Ruhestand, während kleinere Alterskohorten nachrücken. Bis zum Jahr 2030 könnten in Hessen gut 240.000 Fachkräfte fehlen. Zwei Drittel davon werden voraussichtlich Fachkräfte mit Berufsabschluss und ein Drittel Fachkräfte mit akademischem Abschluss sein. Gleichzeitig wird bei den Arbeitskräften ohne Berufs- oder Studienabschluss ein Überhang von knapp 18.000 Personen prognostiziert (Larsen et al. 2024). Für Wirtschaft und Gesellschaft ergibt sich somit die doppelte Herausforderung, einerseits die Gewinnung und Bindung von Fachkräften mit Berufs- oder Studienabschluss zu organisieren und andererseits Arbeitslosigkeit bei Arbeitskräften ohne Berufs- und Studienabschluss entgegenzuwirken. Die Berufsausbildung bildet ein zentrales Handlungsfeld bezüglich beider Herausforderungen. Das von der Hessischen Landesregierung initiierte und im April 2025 bis 2029 verlängerte „Bündnis Ausbildung Hessen“ zielt ausdrücklich darauf ab, Fachkräftesicherung durch duale berufliche Ausbildung voranzutreiben. Ein besonderes Augenmerk liegt dabei auf der „Unterstützung von individuell oder strukturell benachteiligten Menschen, die am Übergang von der Schule in den Beruf oft vor zusätzlichen Herausforderungen stehen“ (Hessisches Ministerium für Wirtschaft, Energie, Verkehr, Wohnen und ländlichen Raum 2025). In Deutschland ist die Zahl der neu abgeschlossenen Verträge für duale Ausbildungsstellen im Jahr 2023 im Vergleich zum Vorjahr um 3 Prozent gestiegen, in Hessen sogar um 6 Prozent auf knapp 36.000. Dabei nahm die Anzahl der Neuverträge in Industrie und Handel um 6 Prozent, im Handwerk sogar um 7 Prozent zu. Das Vor-Corona-Niveau konnte damit aber immer noch nicht wieder erreicht werden. Abermals zurückgegangen – in Hessen wie im Bund – ist die Zahl der dual ausbildenden Betriebe. In Hessen ist der Rückgang um 1 Prozent gegenüber dem Vorjahr auf gut 30.000 Betriebe allein auf Kleinstbetriebe mit bis zu 9 Beschäftigten zurückzuführen (Kuse 2024). Hier stellt sich die Frage, inwieweit Betriebe nicht ausbilden dürfen oder wollen und welche Gründe sie ggf. für ihren Ausbildungsverzicht geltend machen. Der Berufsbildungsbericht 2024 zeigt für den Bund, dass Betriebe mit freien Ausbildungsplätzen und noch unversorgte Bewerbende im Jahr 2023 häufig nicht zueinander gefunden haben (Bundesministerium für Bildung und Forschung 2024). Ohne Ausbildungsplatz und in der Folge ohne beruflichen Abschluss bleiben insbesondere junge Erwachsene, die keinen Schulabschluss erreicht haben. Das hat Folgen: Die Arbeitslosenquote von Personen ohne abgeschlossene Berufsausbildung fiel nach Angaben der Bundesagentur für Arbeit (2024) im Jahr 2023 mehr als sechs Mal so hoch aus wie bei Personen mit beruflichem oder akademischem Abschluss. In Hessen lag der Anteil der Schulabgehenden ohne Hauptschulabschluss im Jahr 2023 bei 6 Prozent (Statistisches Bundesamt 2024). Es stellt sich die Frage, inwieweit Betriebe bereit sind, Kompromisse einzugehen, indem freie Ausbildungsplätze an Bewerbende ohne Schulabschluss vergeben werden und welche Voraussetzungen hierfür gegeben sein müssen. Die Auswertungen zum IAB-Betriebspanel 2024 stehen unter dem Rahmenthema „Betrieblicher Alltag zwischen (schmerzhaften) Kompromissen und neuen Herausforderungen in den Betrieben in Hessen“. Der erste Report hat die aktuelle Personalsituation der Betriebe in Hessen in den Blick genommen. Der hier vorliegende zweite Report fokussiert auf die betriebliche Ausbildung. Kapitel 1 widmet sich der Ausbildungsbeteiligung der Betriebe und den im abgeschlossenen Ausbildungsjahr 2023/24 angebotenen und besetzten bzw. nicht besetzten Ausbildungsplätzen. Anschließend thematisiert Kapitel 2 Ausbildungsabschlüsse und Übernahmequoten. Im dritten Kapitel erfolgt eine Analyse der im neuen Ausbildungsjahr 2024/25 abgeschlossenen Ausbildungsverträge. Kapitel 4 untersucht die Berücksichtigung von Bewerberinnen und Bewerbern ohne Schulabschluss bei der Vergabe von Ausbildungsplätzen, und in Kapitel 5 werden die Gründe für den Ausbildungsverzicht ausbildungsberechtigter Betriebe analysiert. Der Report wird mit einem Resümee abgeschlossen." (Textauszug, IAB-Doku)

Abstract

"This paper assesses wage setting and wage dynamics in a search and matching framework where (i) workers and firms on occasion can meet multilaterally; (ii) workers can recall previous encounters with firms; and (iii) firms cannot commit to future wages and workers cannot commit to not searching in the future. The resulting progression of wages (from firms paying just enough to keep their workers) yields a compensation structure consistent with well established but difficult to reconcile observations on pay dynamics within jobs at firms. Along with wage tenure effects, serial correlation in wage changes and wage growth are negatively correlated with initial wages." (Author's abstract, IAB-Doku, © 2025 The Author.

Abstract

"Do employers seek to attract individuals with more education because it enhances human capital or because it signals higher levels of pre-existing traits? We experimentally vary master’s degree completion rates on applicant résumés and examine how this influences candidates’ desirability and employer perceptions of their productive characteristics. Our findings show that while a completed master’s degree increases desirability, an incomplete master’s degree is perceived by human resource managers as less favorable than a bachelor’s degree. This suggests that employersprefer candidates with higher education mainly because they view the degree as a signal of pre-existing productive traits. Consistent with this, employers perceive both cognitive and non-cognitive traits as stronger in master graduates but non-cognitive traits as weaker in master dropouts compared to bachelor’s degree holders. Overall, perceived cognitiveand non-cognitive traits play a larger role in determining a candidate ’s attractiveness than expertise. This paper thus provides causal evidence on the origins of the education premium." (Author's abstract, IAB-Doku) ((en))

Venables, Anthony J. (2025): Location choice when the number of jobs matters: Matching in spatial equilibrium. (CEP discussion paper / Centre for Economic Performance 2087), London, 22 S.

Abstract

"The idea that people want to go to where the jobs are is intuitive yet is absent from the standard quantitative spatial modelling approach in which location choices are guided by prices, without reference to quantities (the number of jobs in a place). The purpose of this paper is to fill this gap by making jobs, as well as places, the objects of household choice. This involves minor change to the modelling approach used in the literature and provides a simple description of labour market matching. Similar modification of the modelling of firms’ location choices captures the idea that these are shaped by both wage costs and the availability of workers with appropriate skill. These modifications yield powerful agglomeration forces, as workers’ location choices become positively influenced by the number of jobs in a place, and firms’ decision are shaped by the number of workers with appropriate skills. Results are established analytically and in a regional model in which the equilibrium distributions of workers and sectors are demonstrated." (Author's abstract, IAB-Doku) ((en))

Abstract

"This article builds upon the body of literature confirming that aesthetics matter for finding work by investigating how gatekeepers reflect on the relevance of appearances in their evaluations of job candidates. Starting from the notion that in hiring the relevance of appearance conflicts with ideals of meritocracy and fairness, we seek to understand how gatekeepers solve this dispute and how they morally legitimize the importance of aesthetics. The analyses are based on in-depth interviews with 40 employee gatekeepers from the cultural (n = 17) and corporate (n = 23) sector, and show that although the gatekeepers problematize the importance of beauty, they do acknowledge that it plays a role in their evaluations. Three cultural repertoires for solving this contradiction and for legitimizing appearances as a hiring criterion are discerned from the data: (1) beauty as a business case; (2) appearances express personality; (3) looking right is a matter of effort. What the gatekeepers try to do is to come to a hiring decision using evaluation criteria that can be considered contextually legitimate. Yet, this can lead to applying evaluation criteria and, more structurally, labor market outcomes that they find morally problematic. This study highlights the relevance of cultural repertoires in processes of legitimation for understanding reproductions of inequalities related to appearances." (Author's abstract, IAB-Doku) ((en))

Wee, Shu Lin (2025): Optimal unemployment insurance with multiple applications. In: Journal of monetary economics, Jg. 154. DOI:10.1016/j.jmoneco.2025.103798

Abstract

"This paper examines how unemployment transfers should be allocated over the business cycle. When risk-averse workers can submit multiple applications, the optimal UI policy is countercyclical. In contrast, optimal policy in a standard search model featuring one-to-one matching is procyclical. In the latter, more generous UI during a downturn discourages search effort, dampening job creation. In the former, decreased search effort aids job creation. Because firms cannot coordinate and commit to not making the same worker an offer, lower search effort by reducing the number of applications sent mitigates this coordination friction. This in turn boosts job creation incentives, supporting employment outcomes." (Author's abstract, IAB-Doku, © 2025 The Author. Published by Elsevier B.V.) ((en))

Yeo, Hyesu (2025): Older Worker’s Job Search Activities and Employment Transition. In: Research on Aging, S. 1-16. DOI:10.1177/01640275251343107

Abstract

"This study investigated job search patterns among American older workers. Data from the 2016-2018 Health and Retirement Study included 1501 individuals aged 50+ who were looking for jobs in 2016. Latent Class Analysis (LCA) was conducted to identify job search patterns based on nine types of job search activities. Multinomial logistic regression was then used to examine membership in each class. Five job search patterns emerged from the LCA analysis, including No Ads, Ads only, Friends & Ads, Phone & Ads, and Agencies & Ads. Employment transitions were related to job search patterns. Unemployed older workers, despite utilizing more diverse job search methods, were less likely to secure new jobs compared to their employed peers. These findings highlight the need for workforce development programs to focus on workplace skill-building training and educational opportunities before becoming unemployed and age-friendly workforce development tailored to older workers with low-skilled and low income."

Abstract

"Extant literature points to the gender, parenthood, and social status of job applicants as crucial factors influencing employers’ hiring preferences and behaviors. However, little is known about whether and to what extent the intersection of these attributes leads to specific forms of hiring discrimination. This study aims to fill this research gap by examining whether labor market (dis)advantages related to gender, parenthood, and social status occur in an additive or interactive relationship. We conducted a factorial survey experiment in which more than 2,500 UK-based individuals with recruiting experience rated the profiles of fictitious candidates for various job vacancies. We found significant and substantial discrimination against mothers, indicating the existence of a cumulative disadvantage between being a woman and having children, while high-status candidates were more favourably positioned, albeit with noteworthy differences depending on how social status was signalled. Most interestingly, the motherhood penalty was significantly reduced (up to almost half) for high-status candidates, suggesting a compensatory effect of signalling a high status. This novel evidence in the British context highlights the importance of examining the intersection of different dimensions of discrimination and inequality." (Author's abstract, IAB-Doku) ((en))

Abstract

"This paper analyses how labor market heterogeneity affects unemployment, productivity and business cycle dynamics. To this aim, we set up a model with asymmetric search and matching frictions across skilled and unskilled workers, and endogenous productivity through R&D investment and intangible capital accumulation. Skill mismatch and skill-specific labor market institutions have three main effects on business cycles and growth dynamics. First, the relative scarcity of skilled workers increases the natural rate of unemployment and reduces total factor productivity with long-run effects on the growth rate of output. Second, skill heterogeneity in the labor market generates asymmetric outcomes and amplifies measures of employment, wages and consumption inequality. Finally, the model provides important insights for the Phillips and Beveridge curves. Incorporating skill heterogeneity leads to a flattening of the Phillips curve as wages and unemployment respond unevenly across skill types. Also, the model generates sideward shifts of the Beveridge curve following business cycle shocks, with the extent of these shifts depending on the degree of skill heterogeneity."

Abstract

"If women are more sensitive to listed qualifications in job ads, does lowering the bar draw in relatively more women and increase diversity in the applicant pool? We examine this question by randomizing 60,000 viewers into one of two job ad versions for over 600 corporate jobs at Uber, where the treatment removed optional and superfluous qualifications. There are two main findings. First, job seekers of both genders respond to qualifications: applications increase by 7%, owing to similar increases in the number of applications from men and women. Second, reducing the qualifications impacts the type of individual who chooses to apply differently by gender. Reducing the qualifications draws in less skilled women and causes an outflow of some highly skilled women. Conversely, the treatment draws in men from across the skill distribution, including the upper end. We find gender differences in application behavior and explore potential mechanisms in a separate, large-scale survey using the RAND American Life Panel. These results highlight that sensitivity to listed requirements is complex, and simply lowering the qualifications in job postings is not guaranteed to increase applicant diversity."

Abstract

"How informative are job ads about the actual pay and amenities offered by employers? Using a comprehensive database of job ads posted by Norwegian employers, we develop a methodology to systematically classify the information on both pay and non-pay job attributes advertised in vacancy texts. We link this information to measures of employer attractiveness, which we derive from a job search model estimated on observed wages and worker mobility flows. About 55 percent of job ads provide information related to pay and nearly all ads feature information on non-pay attributes. We show that publicly advertised job attributes are meaningful predictors of employer attractiveness, and non-pay attributes are about as predictive as pay-related attributes. High-pay employers mention pay-related attributes more often, while high-amenity employers are more likely to advertise flexible working hours and contract duration."

Avery, Mallory, Andreas Leibbrandt & Joseph Vecci (2024): Does Artificial Intelligence Help or Hurt Gender Diversity? Evidence from Two Field Experiments on Recruitment in Tech. (CESifo working paper 10996), München, 70 S.

Abstract

"The use of Artificial Intelligence (AI) in recruitment is rapidly increasing and drastically changing how people apply to jobs and how applications are reviewed. In this paper, we use two field experiments to study how AI recruitment tools can impact gender diversity in the male-dominated technology sector, both overall and separately for labor supply and demand. We find that the use of AI in recruitment changes the gender distribution of potential hires, in some cases more than doubling the fraction of top applicants that are women. This change is generated by better outcomes for women in both supply and demand. On the supply side, we observe that the use of AI reduces the gender gap in application completion rates. Complementary survey evidence suggests that anticipated bias is a driver of increased female application completion when assessed by AI instead of human evaluators. On the demand side, we find that providing evaluators with applicants' AI scores closes the gender gap in assessments that otherwise disadvantage female applicants. Finally, we show that the AI tool would have to be substantially biased against women to result in a lower level of gender diversity than found without AI." (Author's abstract, IAB-Doku) ((en))

In this paper, we examine listed skills on individuals’ LinkedIn profiles in the United States between 2015 and 2021, both those members add themselves and skills for which they are endorsed from others in their network. We use an inverse probability weighted proportional hazards model with time varying covariates to estimate the relationship between listed skills on shortening employment gaps (time between jobs). We find that, for self-added and peer-endorsed skills respectively, an additional ten skills on the profile decreases median employment gap duration by about 0.7 and 0.4 months, from a median baseline of around 6 months gap. Individuals with no education listed on their profile have the largest benefit from listed skills in terms of reducing employment gaps. Disruptive tech and soft skills also are related to higher returns. Additionally, skills added during the employment break have a substantially stronger relationship than pre-existing added skills. More experienced workers have larger returns than less experienced workers, consistent with the hypothesis that these skills are otherwise difficult to signal to potential employers. These findings are consistent with online job markets’ use of technology offering more efficient ways to signal skills, shortening time to reemployment."

Abstract

"Returns to labor mobility have too often escaped the attention they deserve as conduits of important forces in macro-labour models. These returns are shaped by calibrations of productivity processes that use theoretical perspectives and data sources from (i) labour economics and (ii) industrial organization. By investigating earlier prominent studies, we conclude that the focus on firm size dynamics and shocks intermediated through neo-classical production functions in (ii) yields large returns to labor mobility that are robust to parameter perturbations. In contrast, the reliance on statistics in labor economics to calibrate per-worker productivity processes in (i) can give rise to fragilities in the sense that parameter perturbations that generate similar targeted statistics can have very different implications for returns to labor mobility."

Baran, Jan A. (2024): Overeducation in the EU: Gender and regional dimension. In: Labour Economics, Jg. 90. DOI:10.1016/j.labeco.2024.102603

Abstract

"The paper investigates factors associated with the overeducation risk in the EU, with a specific focus on gender and regional variables. The study tests Frank's theory of differential overqualification, which suggests that women are more likely to be overeducated than men, especially in small local labor markets. Although women's overeducation rates usually exceed those of men, the study's results show limited validity of Frank's model due to a nuanced relationship by which gender is linked to overeducation. They suggest that gender differentiates the overeducation risk in combination with care responsibilities, whilst easier access to childcare facilities is associated with a lower risk of overeducation among women in households with young children. Moreover, migrant women are found to be more at risk of overeducation, compared to both migrant men and non-migrants. Contrary to Frank's theory, the degree of urbanisation is found irrelevant for overeducation. Furthermore, the study shows the evidence of growing incidence of overeducation in the EU in 2011–2018."

Barlevy, Gadi, R. Jason Faberman, Bart Hobijn & Ayşegül Şahin (2024): The Shifting Reasons for Beveridge Curve Shifts. In: The Journal of Economic Perspectives, Jg. 38, H. 2, S. 83-106. DOI:10.1257/jep.38.2.83

Abstract

"We discuss how the relative importance of factors that contribute to movements of the US Beveridge curve has changed from 1959 to 2023. We review these factors in the context of a simple flow analogy used to capture the main insights of search and matching theories of the labor market. Changes in inflow rates, related to demographics, accounted for Beveridge curve shifts between 1959 and 2000. A reduction in matching efficiency, that depressed unemployment outflows, shifted the curve outwards in the wake of the Great Recession. In contrast, the most recent shifts in the Beveridge curve appear driven by changes in the eagerness of workers to switch jobs. Finally, we argue that, while the Beveridge curve is a useful tool for relating unemployment and job openings to inflation, the link between these labor market indicators and inflation depends on whether and why the Beveridge curve shifted. Therefore, a careful examination of the factors underlying movements in the Beveridge curve is essential for drawing policy conclusions from the joint behavior of unemployment and job openings."
