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

"Dieses Diskussionspapier zeigt, wie Veränderungen des Arbeitsmarkt-Mismatch auf die Komponenten Arbeitslosigkeit, offene Stellen und Matchingeffizienz zurückgeführt werden können. Wir stellen fest, dass die Arbeitslosigkeit der wichtigste Faktor ist und auch die zyklischen Schwankungen bestimmt, während die Beiträge der offenen Stellen geringer und antizyklisch sind. Wir unterscheiden nach der Ursache der Arbeitslosigkeit und zeigen, dass Ströme gegenüber der Beschäftigung den Mismatch verstärken, während dies für Nichtbeschäftigung und Ausbildung / Weiterbildung nicht der Fall ist."

Abstract

"To date, it is unclear in which skills mismatches are most relevant for individuals’ wages, and whether surpluses or deficits in one domain can offset those in another. This study addresses these gaps by examining how mismatches in five key skill domains (ICT, reading, mathematics, science, and reasoning) are linked to individuals’ wages. Utilizing data from the 2016 wave of the German National Educational Panel Study (NEPS) Adult Cohort, our findings reveal that skill deficits consistently result in lower wages, whereas surpluses do not pay off in each domain. Notably, mismatches in ICT skills are most significant for individuals’ wages: ICT deficits not only reduce wages, but can also negate wage benefits from surpluses in other skills. Conversely, ICT surpluses can compensate for wage penalties associated with deficits in other domains. These findings underscore the importance of digital skills for productivity and wage potential in the modern labour market." (Author's abstract, IAB-Doku) ((en))

Abstract

"This study examines the impact of job vacancy information obtained through personal contacts on monetary and nonmonetary job search outcomes. We hypothesise that the effects will be positive for both kinds of outcome, and that these effects may depend on employment status prior to finding a new job. Additionally, we hypothesise that information from professional personal contacts will lead to better job search outcomes than information from private personal contacts. We use panel data from the German Panel Study “Labour Market and Social Security” (PASS) and fixed effects regressions to test these hypotheses. Monetary outcomes are measured by wages and nonmonetary outcomes by job satisfaction. Overall, we find that the employed tend to benefit more than the unemployed. However, the specific pattern differs depending on whether vacancy information stems from personal or professional contacts and on the type of outcome (monetary or nonmonetary)."

Abstract

"Social media platforms, such as Twitter or Instagram, offer easily accessible information – relevant or not – for employers when evaluating candidates for a position. In particular, they tend to be sources of information about individuals’ interests and leisure activities.Because interests are highly stratified by social class (e.g., engagement in highbrow and lowbrow activities), this represents a new way for class to potentially manifest itself in the hiring process. To study discrimination in hiring based on online social class cues, we conducted a pre-registered survey experiment in Germany with samples of employers and non-employers, manipulating job applicants’ class cues on social media(highbrow versus lowbrow). Overall, we found no difference in preferences for the candidates displaying highbrow and lowbrow activities on their social media profiles. However, this masks important differences in the specific activities proxying for class. When these activities have no relevance for the jobs in question, higher-class candidates are preferred. Exploratory analyses show that respondents are more likely to express positive sentiments toward the higher-class profiles, with highbrow activities being positively associated with work-related traits. Our findings highlight the need to consider how digital environments and, more specifically, online social class cues, may contribute to class bias in hiring."

Goller, Daniel, Enzo Brox & Stefan C. Wolter (2026): Imperfect Self-knowledge about Skills and Skill Mismatch. (Working paper / Swiss Leading House 253), Zürich, 40 S., App.

Abstract

"Why do young people sort into poorly fitting occupations? This paper shows that imperfect self-knowledge about skills is an important source of skill mismatch at labor market entry. We use unique data from standardized professional aptitude tests linked to administrative records on educational trajectories and early labor market outcomes in Switzerland. The data allow us to observe objective skills and subjective skill beliefs for many productivity-relevant skills in a high-stakes setting. We document large differences among individuals in how well their beliefs align with their skills. Imperfect self-knowledge predicts misaligned occupational aspirations, higher realized skill mismatch, and a higher probability of dropout. Guided by a Roy-style model of occupational choice with imperfect self-knowledge, we interpret these findings as evidence that distorted self-assessments at the school-to-work transition contribute to the misallocation of talent."

Abstract

"The standard labour market matching function neglects a substantial variation of hirings. A crucial driver of this latent part is the search intensity of job seekers and firms, as well as the placement intensity of employment agencies. However, there is still a lack of integration of all three search and placement intensities into a unified theoretical framework. Their combined labour market effects have not been estimated so far. We feed all three intensities into the theoretical framework of a labour market matching function to estimate their impact on the job finding rate – effects which are not settled a priori. This could provide important stylised facts for subsequent theory building. For measuring the search and placement intensities, we use big data on online activity obtained from the job exchange of the German Federal Employment Agency and from its internal placement-software. The results show that all three intensities significantly contribute to the variation in job findings beyond vacancies and unemployment. During the COVID-19 crisis, reduced search intensities accounted for 44 percent of lost hirings and 16 percent of the labour market related increase in unemployment."

Abstract

"This paper analyzes the effects of firms posting multiple but varying number of vacancies, hence differing in their market power, in professional labor markets. I find that strategic wage Posting does, in general, not result in an efficient assignment of workers to firms. This is because firms with a larger number of vacancies pay on average lower wages than their competitors due to alack of within-firm rivalry. If highly productive firms hire more, the resulting welfare loss dueto mismatch may be substantial. Moreover, I provide a potential explanation why firms postuniform wages, missing out on more-skilled workers." (Author's abstract, IAB-Doku) ((en))

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)

Carlini, Giacomo (2025): Essays in Macroeconomics and Labor Economics. 147 S.

Abstract

"The first chapter investigates why assortative matching between workers and firms is stronger in large cities than in small cities. I develop a search and matching model with heterogeneous workers and firms to examine how worker composition and labor market frictions affect sorting. Calibrating the model to German employer-employee data, I find that matching efficiency is key to explaining differences in assortative matching across cities. This effect is amplified by a more dispersed worker productivity dispersion. The model shows that around 5% of the GDP gap between large and small cities is attributable to differences in assortative matching, underscoring the role of local labor market frictions and productivity distributions in spatial inequality. The second chapter explores how task-biased technological adoption affects GDP gaps across countries. We introduce a country-specific measure of task intensity and document that as GDP increases, routine work declines while cognitive work rises. Moreover, differences in task content within occupations explain over half of the cross-country differences in routine work. Using a production framework where technology is task-specific and occupations are aggregates of tasks, we estimate task-specific productivities across countries. A counterfactual exercise suggests that reducing dispersion in task-biased technology adoption could shrink the average GDP gap with the United States by 25%. The third chapter examines sectoral labor productivity growth in the U.S. over 50 years, highlighting routine- and skill-biased technical change. I show that routine labor productivity has grown fastest, with skill-biased technical change benefiting skilled workers while unskilled productivity declined, especially in services. Finally, to disentangle the role of different labor-augmenting technological change, I extend the framework to account for heterogeneity in both occupations and skills."

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."

Although the education and skill mismatch measures are constructed using different methods and differ in size, the output costs are similar between the two measures."

Abstract

"Standard business cycle models with search and matching frictions in the labour market increasingly rely on the assumption that firms face hiring, as opposed to, search costs in recruiting workers. We show that although this modification im-proves the model's empirical performance, it causes the matching function to play no role in macroeconomic dynamics. Assuming both costs can overcome this short-coming but for reasonable parameter values it implies that matching efficiency shocks have no effects." (Author's abstract, IAB-Doku) ((en))

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."

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

"In online labor markets, reputation determines both job opportunities and pay and even small disparities can translate into significant economic differences. While gender-related bias in reputational metrics such as likes, reviews, and ratings has been empirically documented, the mechanisms through which they arise remain insufficiently understood. This study presents results from an online experiment, varying workers’ gender, domain, and performance, to investigate how expectations about workers are formed and how they affect subsequent evaluations. Drawing on Expectation Disconfirmation Theory and Role Congruity Theory, we test whether the effect of disconfirmation (i.e., discrepancies between expected and actual performance) on evaluations varies with congruity (i.e., stereotypical fit between gender and domain). Contrary to our hypothesis, workers in congruent settings do not elicit higher expectations than those in incongruent roles. Similarly, the effect of positive and negative disconfirmation does not vary with congruity. However, exploratory analyses suggest that congruity does affect expectations and evaluations when individuals hold strong gender-domain associations. In case of stereotypical associations, individuals expect higher performance of workers in congruent domains and evaluate them more leniently if they fail to meet expectations. Our findings contribute to understanding why identical performances might be judged differently depending on gender-domain associations, expectations, and disconfirmation."

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

"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."

Abstract

"We analyze the employment effects of directing job seekers' applications toward establishments likely to recruit. We run a two-sided randomization design involving about 800,000 job seekers and 40,000 establishments, based on an empirical model that recommends each job seeker to firms so as to maximize total potential employment. Our intervention induces a 1% increase in job finding rates for short term contracts. This impact comes from a targeting effect combining (i) a modest increase in job seekers' applications to the very firms that were recommended to them, and (ii) a high success rate conditional on applying to these firms. Indeed, the success rate of job seekers' applications varies considerably across firms: the efficiency of applications sent to recommended firms is 2.7 times higher than the efficiency of applications to the average firm. This suggests that there can be substantial gains from better targeting job search, leveraging firm-level heterogeneity." (Author's abstract, IAB-Doku) ((en))

Abstract

"The quality of an employment match is a central concept in labor economics. It is relevant for evaluating the welfare impact of labor market policies, and for our understanding of labor market dynamics. This paper reviews the challenges associated with measuring match quality. We first review measures commonly used in the literature, their advantages, and drawbacks. We then present novel evidence from a survey sample of US employees where alternative measures were collected simultaneously. We show that while some of these measures correlate well, others do not. Finally, we present additional partial evidence on the correlations between measures based on the National Longitudinal Survey of Youth (NLSY79), a substantially larger and nationally representative survey. The takeaway message is a word of caution regarding the interpretation of some of these measures and specific concerns regarding using wages and tenure as indicators of match quality."

Abstract

"This paper documents that labor search and matching frictions generate countercyclical uncertainty because the inherent nonlinearity in the flow of new matches makes employment uncertainty increasing in the number of people searching for work. Quantitatively, this mechanism is strong enough to explain uncertainty and real activity dynamics, including their correlation. Through this lens, uncertainty fluctuations are endogenous responses to changes in real activity that neither affect the severity of business cycles nor warrant policy intervention, in contrast with leading theories of the interaction between uncertainty and real activity dynamics."

"I study the distributions of unemployment, vacancies, and wages across local labor markets in an economy where workers and jobs are matched and mismatched based on more explicit assumptions and aggregation principles than in the reduced-form aggregate matching-function approach. The endogenous matching process formulated here is flexible and has practical value for applied work. Local and aggregate labor market adjustments to local productivity and aggregate demand shocks reproduce empirical Beveridge and wage curve patterns, offer an alternative perspective on empirical indices of mismatch unemployment, and deliver an endogenous and commonly used reduced-form aggregate matching function."

Abstract

"Wir analysieren, wie sich das Matching zwischen Betrieben und Beschäftigten über das Erwerbsleben durch Jobmobilität verändert. Wir nutzen deutsche administrative Daten, die sowohl Informationen über Beschäftigte als auch Betriebe enthalten. Um assortatives Matching zu messen, berechnen wir die Korrelation zwischen zeitkonstanten Lohnkomponenten von Betrieben und Beschäftigten, welche wir aus einer Lohndekomposition im Stil von Abowd/Kramarz/Margolis (1999) ziehen. Zudem benutzen wir ein neues Maß für assortatives Matching, welches auf der Distanz zwischen diesen Lohnkomponenten basiert. Beide Maße zeigen, dass der Grad des assortativen Matchings im Durchschnitt mit jedem weiteren Betriebswechsel ansteigt. Bei Beschäftigten mit einer hohen zeitkonstanten Lohnkomponente kann dies durch Job Ladder Modelle erklärt werden, denn die Beschäftigten bewegen sich zu Firmen mit höheren Lohnkomponenten. Dahingegen sind Beschäftigte mit niedrigerer Lohnkomponente am Anfang des Erwerbslebens in weniger assortativen Matches zu finden, da sie es ebenfalls schaffen, zu Beginn die Job Ladder hinaufzuklettern. Für sie beginnt der Anstieg des assortativen Matchings erst nach dem dritten Job, wenn sie von der Job Ladder fallen. Die Entwicklung des assortativen Matchings ist zudem relevant für die Lohnungleichheit im Lebensverlauf. Wir zeigen, dass der Anstieg des assortativen Matchings circa 25 Prozent des Anstiegs der Lohnungleichheit im Lebensverlauf erklären kann." (Autorenreferat, IAB-Doku)

Abstract

"A principal often needs to match agents to perform coordinated tasks, but agents can quit or slack off if they dislike their match. We study two prevalent approaches for matching within organizations: Centralized assignment by firm leaders and self-organization through market-like mechanisms. We provide a formal model of the strengths and weaknesses of both methods under different settings, incentives, and production technologies. The model highlights tradeoffs between match-specific productivity and job satisfaction. We then measure these tradeoffs with data from a large organization’s internal talent market. Firm-dictated matches are 33% more valuable than randomly assigned matches within job categories (using the firm’s preferred metric of quality). By contrast, preference-based matches (using deferred acceptance) are only 5% better than random but are ranked (on average) about 38 percentiles higher by the workforce. The selforganized match is positively assortative and helps workers grow new skills; the firm’s preferred match is negatively assortative and harvests existing expertise."

Abstract

"I define occupations that are employed in more industries as “broader ” occupations. I study the implications of broadness for mismatch of the unemployed and vacancies across occupations and industries. I empirically find that workers in broader occupations are better insured against industry specific shocks. A recent literature has found that mismatch did not significantly contribute to the rise in unemployment during the Great Recession. I build a general equilibrium model that uses occupational broadness as a microfoundation of mismatch. The model uncovers a general equilibrium channel that realigns the strong crosssectional effects of mismatch with its missing aggregate impact. I argue that mismatch across occupations and industries cannot significantly contribute to aggregate unemployment fluctuations" (Author's abstract, IAB-Doku) ((en))

"We report on a laboratory experiment testing the predictions of the Diamond–Mortensen–Pissarides (DMP) search-and-matching model, which is a workhorse, decentralized model of unemployment and the labor market. We focus on the job vacancy posting problem that firms face in the DMP model. We explore the model’s comparative statics predictions concerning variations in the separation rate, the vacancy posting cost, and the firm’s surplus earned per employee. Across all treatments, we find strong evidence for an inverse relationship between vacancies and unemployment, consistent with the Beveridge curve. We also find that the results of our various comparative statics exercises are in-line with the predictions of the theory." (Author's abstract, IAB-Doku, © 2024 Elsevier) ((en))

Abstract

"This paper develops a search and matching framework in which workers are characterized by asymmetric reference-dependent reciprocity and firms set wages by considering the effect that these can have on workers’ effort and, therefore, on output. The cyclical response ofeffort to wage changes can considerably amplify shocks, independently of the cyclicality of the hiring wage, which becomes irrelevant for unemployment volatility, and firms’ expectations of downward wage rigidity in existing jobs increases the volatility of job creation. The model is consistent with evidence on hiring and incumbents’ wage cyclicality, and provides novel predictions on the dynamics of effort." (Author's abstract, IAB-Doku) ((en))

Abstract

"We study the link between firm productivity and the wages that firms pay. Guided by a search-matching model with large firms, worker and firm heterogeneity, and production complementarities, we infer firm productivity by estimating firm-level production functions. Using German data, we find that the most productive firms do not pay the highest wages. Worker transitions from high- to medium-productivity firms are on average associated with wage gains. Productivity sorting, that is, the sorting of high-ability workers into high-productivity firms, is less pronounced than the sorting into high-wage firms."

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

"This study provides new evidence on skill requirements in the labor market and shows to what extent skill demand is associated with wages and vacancy duration. In a sample of more than 1.5 million job postings administered by the Austrian public employment service, I identify the most common skill requirements mentioned in job descriptions. Accounting for a broad set of detailed job characteristics, there exists a robust association between the number of skill requirements and wages. In particular, jobs with many skill requirements pay substantially higher wages. While I estimate large effects for managerial and analytical skills, associations with most soft skills are small. Employers also need longer to fill vacancies with many skill requirements. Robustness tests show that measurement error is unlikely to explain these results and that the estimates can be replicated using vacancy postings from another job board."

Abstract

"We discuss how the relative importance of factors that contribute to movements of the U.S. Beveridge curve has changed from 1960 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 1960 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. We argue that, while the Beveridge curve is a useful tool for relating unemployment and vacancies 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."

Abstract

"We estimate the elasticity of vacancy duration with respect to posted wages, using data from the near-universe of online job adverts in the United Kingdom. Our research design identifies duration elasticities by leveraging firm-level wage policies that are plausibly exogenous to hiring difficulties on specific job vacancies, and control for job and market-level fixed-effects. Wage policies are defined based on external information on pay settlements, or on sharp, internally-defined, firm-level changes. In our preferred specifications, we estimate duration elasticities in the range −3 to −5, which are substantially larger than the few existing estimates." (Résumé d'auteur, IAB-Doku) ((en))

Abstract

"Firmen und Arbeitnehmer/-innen finden überwiegend über Stellenanzeigen, persönliche Kontaktnetzwerke oder die Bundesagentur für Arbeit zueinander. All diese Suchkanäle tragen dazu bei, Friktionen am Arbeitsmarkt zu verringern. In diesem Papier untersuchen wir, inwieweit diese Suchkanäle unterschiedliche Auswirkungen auf den Arbeitsmarkt haben. Anhand einer neuen Datenverknüpfung aus administrativer Daten und Umfragedaten zeigen wir: (i) Niedriglohnfirmen und Niedriglohnbeziehende finden vermehrt über Netzwerke oder die Bundesagentur für Arbeit zueinander, währendessen Hochlohnfirmen und Hochlohnbeziehende häufiger über Stellenanzeigen zusammenkommen. (ii) Dabei nutzen Firmen Stellenanzeigen vor allem bei der Abwerbung und Gewinnung von Hochlohnbeziehenden. Im Vergleich zu anderen Suchkanälen, werden Stellenanzeigen auch vermehrt von Beschäftigten beim Aufstieg auf der Karriereleiter genutzt. Um die Auswirkungen dieser Beobachtungen auf die aggregierte Beschäftigung, die Löhne und die Arbeitsmarktsortierung zu bewerten, schätzen wir strukturell ein Gleichgewichtsmodell, das sich durch Karriereleitern, zweiseitige Heterogenität, mehrere Suchkanäle und endogene Einstellungsintensität auszeichnet. Die Schätzung zeigt, dass Netzwerke der kosteneffizienteste Kanal sind, der es Firmen ermöglicht, schnell einzustellen, aber auch Arbeitskräfte mit geringeren durchschnittlichen Fähigkeiten anzuziehen. Stellenanzeigen sind der kostspieligste Kanal, erleichtern die Einstellung von Arbeitnehmern/-innen mit höheren Fähigkeiten und sind für die Sortierung zwischen Beschäftigten und Firmen am wichtigsten. In kontrafaktischen Berechnungen zeigt sich, dass obwohl die Bundesagentur für Arbeit die geringste Einstellungswahrscheinlichkeit bietet, ihre hypothetische Abschaffung beträchtliche Folgen hätte. Die Gesamtbeschäftigung würde um mindestens 1,4 Prozent sinken und die Lohnungleichheit steigen." (Autorenreferat, IAB-Doku)

Abstract

"Recruitment intensity is important for the matching process in the labor market. Using unique linked survey-administrative data, we investigate the relationships between hiring and recruitment policies at the establishment level. Faster hiring goes along with higher search effort, lower hiring standards and more generous wages. We develop a directed search model that links these patterns to the employment adjustments of heterogenous firms. The model provides a novel structural decomposition of the matching function that we use to evaluate the relative importance of these recruitment policies at the aggregate level. The calibrated model shows that hiring standards play an important role in explaining differences in matching efficiency across labor markets defined as region/skill cross products and for the impact of labor market policy, whereas search effort and wage policies play only a minor role."

Abstract

"Following a panel ARDL approach, we appraise the impact of various indicators of active and passive labor-market policies within the framework of the Beveridge curve across fourteen OECD countries from 1985 to 2013, controlling for other factors, both institutional (tax wedge) and structural (technological progress, globalization). We embed the role of these variables within the specification of the Beveridge curve, finding that the generosity of unemployment benefits has a detrimental impact on labor-market matching, with the duration of benefits and the strictness of the rules pertaining to the deployment of benefits taking a key role in driving this result. Among active labor-market policies, employment incentives and especially training have a favourable effect on matching. There is evidence of a virtuous interaction between active and passive policies. A significantly detrimental role emerges for the tax wedge. These results are consistent across various specifications, and structural relationships are stable throughout the 2008–2013 period." (Author's abstract, IAB-Doku) ((en))

Abstract

"Worker sorting into tasks and occupations has long been recognized as an important feature of labor markets. But this sorting may be inefficient if jobseekers have inaccurate beliefs about their skills and therefore apply to jobs that do not match their skills. To test this idea, we measure young South African jobseekers’ communication and numeracy skills and their beliefs about their skill levels. Many jobseekers believe they are better at the skill in which they score lower, relative to other jobseekers. These beliefs predict the skill requirements of jobs where they apply. In two field experiments, giving jobseekers their skill assessment results shifts their beliefs toward their assessment results. It also redirects their search toward jobs that value the skill in which they score relatively higher—using measures from administrative, incentivized task, and survey data—but does not increase total search effort. It also raises earnings and job quality, consistent with inefficient sorting due to limited information." (Author's abstract, IAB-Doku) ((en))

Abstract

"This paper studies the relationship between search effort and workers’ ranking by employers. In order to do so, we propose a matching model in which employers have common preferences over a continuum of heterogeneous workers who choose a number of applications to send out. We show that in equilibrium, the relationship is hump-shaped for sufficiently high vacancy-to-worker ratios, that is, highly-ranked and lowly-ranked workers send out fewer applications than workers of mid-range rank. This arises due to two opposing forces driving the incentives of applicants. Increasing the number of applications acts as insurance against unemployment, but is less effective when the probability of success for each application is low. This mechanism exacerbates the negative employment outcomes of low-rank workers—hence, in contrast to the market equilibrium, in the social planner’s solution, the number of applications monotonically decrease in rank."

Abstract

"Employment in mismatch (low-skill) jobs is a potential factor in the emigration of highly qualified workers. At the same time, high-skilled emigration and emigration of mismatch workers can free up positions for stayers. In bad times, it could also amplify demand losses and the unemployment spell, which in turn affects the mismatch rate. In this paper, we investigate the link between vertical skills mismatch and emigration of both non-mismatch and mismatch workers in a DSGE model. The model features also skill and wealth heterogeneous households, capital-skill complementarity (CSC) and labor frictions. We find that an adverse productivity shock reduces investment and primarily hurts the high-skilled who react by turning to both jobs abroad and mismatch jobs in the domestic labor market. A negative shock to government spending crowds-in investment and primarily hurts the low-skilled who thus turn to jobs abroad. Following the fiscal cut, the high-skilled instead reduce their search for mismatch employment and later they also reduce their search for jobs abroad." (Author's abstract, IAB-Doku) ((en))

Minni, Virginia (2023): Making the invisible hand visible: Managers and the allocation of workers to jobs. (CEP discussion paper / Centre for Economic Performance 1948), London, 80 S.

Abstract

"Why do managers matter for firm performance? This paper provides evidence of the critical role of managers in matching workers to jobs within the firm using the universe of personnel records from a large multinational firm. The data covers 200,000 white-collar workers and 30,000 managers over 10 years in 100 countries. I identify good managers as the top 30% by their speed of promotion and leverage exogenous variation induced by the rotation of managers across teams. I find that good managers cause workers to reallocate within the firm through lateral and vertical transfers. This leads to large and persistent gains in workers' career progression and productivity. Seven years after the manager transition, workers earn 30% more and perform better on objective performance measures. In terms of aggregate firm productivity, doubling the share of good managers would increase output per worker by 61% at the establishment level. My results imply that the visible hands of managers match workers' specific skills to specialized jobs, leading to an improvement in the productivity of existing workers that outlasts the managers' time at the firm."

Obadić, Alka & Viktor Viljevac (2023): Labour market tightness and matching efficiency in different labour market segments – do differences in education and occupation matter? (EFZG working paper series 2303), Zagreb, 47 S.

Abstract

"This paper analyses the existing educational and occupational structures of several EU member countries and their alignment with the needs of the labour market. Such a situation may indicate a structural mismatch in labour market in which the mismatch between the skills taught in schools and universities and the skills needed in the workplace appears. To evaluate this mismatch, the paper investigates the matching needs of employers and unemployed job seekers by disaggregating the registered employment office data by education and occupation groups in selected EU countries separately. More educated workers, as well as workers in more complex and better-paid occupations, might fare better when it comes to the aggregate labour market trends. For example, economic downturns and increases in unemployment might be felt more heavily by workers with lower education and those who work in professions requiring fewer skills. In this paper, we analyse the data for a selected group of countries (Austria, Croatia, Estonia, Slovenia, and Spain) from 2010 till 2022, using the Beveridge curves and estimate the labour market tightness and matching efficiency for different education and occupation groups. Our results show that differences in education levels and occupation result in relatively small deviations from aggregate trends in the labour market. Aggregate labour market trends therefore strongly impact all groups in the labour market, whether the market is segmented by education levels or by occupation. In other words, both the improvements in the labour market conditions and the worsening of labour market conditions have similar effects across different labour market segments."

Abstract

"The extension of bipolar fuzzy graph is bipolar fuzzy incidence graph (BFIG) which gives the information regarding the effect of vertices on the edges. In this paper, the concept of matching in bipartite BFIG and also for BFIG is introduced. Some results and theorems of fuzzy graphs are also extended in BFIGs. The number of operations in BFIGs such as augmenting paths, matching principal numbers, relation between these principal numbers and maximum matching principal numbers are being investigated which are helpful in the selection of maximum most allied applicants for the job and also to get the maximum outcome with minimum loss (due to any controversial issues among the employees of a company). Some characteristics of maximum matching principal numbers in BFIG are explained which are helpful for solving the vertex and incidence pair fuzzy maximization problems. Lastly, obtained maximum matching principal numbers by using the matching concept to prove its applicability and effectiveness for the applications in bipartite BFIG and also for the BFIG."

Ryan, Rich (2023): Responses of unemployment to productivity changes for a general matching technology. In: Economics Bulletin, Jg. 43, H. 4, S. 1749-1758.

Abstract

"Workers separate from jobs, search for jobs, accept jobs, and fund consumption with their wages. Firms recruit workers to fill vacancies. Search frictions prevent firms from instantly hiring available workers. Unemployment persists. These features are described by the Diamond--Mortensen--Pissarides modeling framework. In this class of models, how unemployment responds to productivity changes depends on resources that can be allocated to job creation. Yet, this characterization has been made when matching is parameterized by a Cobb--Douglas technology. For a canonical DMP model, I (1) demonstrate that a unique steady-state equilibrium will exist as long as the initial vacancy yields a positive surplus; (2) characterize responses of unemployment to productivity changes for a general matching technology; and (3) show how a matching technology that is not Cobb--Douglas implies unemployment responds more to productivity changes, which is independent of resources available for job creation, a feature that will be of interest to business-cycle researchers."

Abstract

"Using longitudinal data from Starting Cohort 4 of the German National Educational Panel Study (NEPS), we examined whether pre-existing strong ties and weak ties in the training company are associated with the risk of premature termination of apprenticeship training in Germany. This is highly relevant for the literature on social capital in the labor market since so far little is known about the role of social contacts for the turnover propensity of labor market entrants. By examining a potentially important factor for a successful labor market integration, our research also adds to both the school-to-work and the social stratification literature. Our empirical results are only partly consistent with our theoretically derived expectations. While contrary to our expectations, we found no association between strong ties and termination probability, weak ties were, as expected, associated with a lower probability of premature training termination among those apprentices who were trained in their desired occupation. Our main results, combined with several robustness checks, let us assume that this is due to better matched training situations." (Author's abstract, IAB-Doku, © 2024 Elsevier) ((en))

At firm level, it features a robust positive correlation with firm productivity, and with managerial turnover leading to an improvement in the quality and experience of management.
