matching – Suchprozesse am Arbeitsmarkt
Offene Stellen bei gleichzeitiger Arbeitslosigkeit - was Arbeitsmarkttheorien u. a. mit "unvollkommener Information" begründen, ist für Unternehmen und Arbeitsuchende oft nur schwer nachzuvollziehen: Unternehmen können freie Stellen nicht besetzen, trotzdem finden Arbeitsuchende nur schwer den passenden Job. Wie gestalten sich die Suchprozesse bei Unternehmen und Arbeitsuchenden, welche Konzessionen sind beide Seiten bereit einzugehen, wie lässt sich das "matching" verbessern?
Diese Infoplattform bietet wissenschaftliche Literatur zur theoretischen und empirischen Auseinandersetzung mit dem Thema.

Abstract
"We ran a field experiment to causally identify the effects of intense survey participation on key labor market outcomes. We randomly excluded individuals willing to sign up for the German Job Search Panel, a high-frequency survey with a focus on job search and wellbeing. Using administrative data on labor market outcomes (e.g., employment, earnings), we find that, on average, survey participation had no effect on labor market outcomes during the year after signing up. Furthermore, there is no strong heterogeneity across subgroups. Overall, this is good news for the validity of survey-based research involving labor market outcomes. We also demonstrate that a comparison of individuals signing up for the survey with individuals not responding to the invitation could have been misleading. Even when controlling for a wide range of observable characteristics, survey participation and the subsequent take up of training programs correlate significantly. This speaks to the importance of experimental research designs in our context." (Author's abstract, IAB-Doku) ((en))

Tholen, Gerbrand (2024): Matching Candidates to Culture: How Assessments of Organisational Fit Shape the Hiring Process. In: Work, Employment and Society, Jg. 38, H. 3, S. 705-722. DOI:10.1177/09500170231155294
Abstract
"Organisational fit represents a crucial criterion in the hiring process. This article aims to understand how employers and external recruitment consultants define and apply organisational fit in professional labour markets, such as engineering, marketing and finance. It also investigates how the use of organisational fit in hiring can lead to social bias within these labour markets. It relies on semi-structured interviews with 47 external recruitment consultants who assist employers in these sectors. The article draws on Relational Inequality Theory to demonstrate how hiring managers and consultants use organisational fit to create and justify boundaries between acceptable and unacceptable candidates. Claim-making supports the rationalisation and legitimisation in the exclusion of groups of candidates. The article critically informs human resource management, business and psychology literature that perceive organisational fit as a largely benign criterion for recruitment. It also extends sociological and critical management literature by delineating three main exclusionary mechanisms in matching candidates for organisational fit." (Author's abstract, IAB-Doku) ((en))

Job search intensity and wage rigidity in business cycles (2024)

Uemura, Yuki (2024): Job search intensity and wage rigidity in business cycles. In: Journal of macroeconomics, Jg. 82. DOI:10.1016/j.jmacro.2024.103624
Abstract
"Search intensity, as well as the aggregate economic condition, is a crucial factor that determines unemployed workers’ success in job searches. Their search intensity is predicted to be procyclical in standard search and matching models. However, many empirical studies show that search intensity is countercyclical. This study examines the job search behavior of unemployed workers over business cycles using a search and matching model that incorporates wage rigidity and a generalized matching function. Unlike previous studies, the proposed model can generate both procyclical and countercyclical search intensities by introducing wage rigidity. This study calibrates the model to the U.S. economy and provides various impulse response analyses. The numerical exercises show that the model successfully and simultaneously reproduces countercyclical search efforts and sizable labor market fluctuations."

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."

Andrieu, Elodie & Malgorzata Kuczera (2023): Minimum Wage and Skills - Evidence from Job Vacancy Data. (TPI working papers / The Productivity Institute 034), Manchester, 62 S.
Abstract
"Low-wage occupations tend to be populated by workers with low levels of education. An increase in the minimum wage, while designed to protect workers in the lower part of the wage distribution, might result in unintended consequences for those same workers. In this paper, we study firms’ reaction to higher minimum wages, exploiting a change to the minimum-wage policy in the UK in 2016. We document how an increase in the minimum wage affects the labour hiring for different education and technical skill levels of workers. The results show that an increase in the minimum wage compressed both the demand for low educated workers and the demand for workers with low levels of technical skills (tech workers) for graduates in low and middle skilled occupations. Using a difference-in-differences framework, we find that a large and unexpected change to the minimum wage led to a 11 percentage point decrease in the proportion of non-graduate vacancies and a 15 percentage point decline in the share of low-tech ads. There is evidence for labour-labour substitution at the low-end of the skill distribution and labour-technology substitution for more educated workers as a way to compensate for labour costs increases."

Abstract
"Skills assessment is essential for today’s labor market.There are many factors hat change the requirements for the workplace. More than ever, it is important to monitor which skills are in high demand so that workers stay employed and ompanies do not lose productivity. This research discusses the relevance of data from online job portals for this task. It then uses a skill extractor in online ob advertisements from Chile to identify and extract the skills employers place n their online job advertisements through skills dictionaries. The study shows modest results when using the European Skills, Competences and Occupations 28ESCO) dictionary but an enhanced and much-improved result when adding an inductively constructed dictionary of the national labor market. Using this method would allow a new input of information to be incorporated into labor arket information systems that would enable better decisions to be made by he various actors in the labor market."

Abstract
"This paper examines the short- and medium-term effects of over- and undereducation on individual wages using a matched employer-employee dataset from 1998 to 2012 and a novel measure of educational mismatch based on the flows of newly hired workers. The findings reveal that the wage differential between adequately matched and mismatched workers decreases substantially once the unobserved heterogeneity of the worker and the firm is considered. Workers' unobserved characteristics explain a large proportion of both the overeducated wage penalty and the undereducated wage premium. Additionally, variations in firms' pay policies contribute to the wage gap among mismatched workers. Finally, findings show that job mismatches have the greatest impact on early-career individuals' wages." (Author's abstract, IAB-Doku, Published by arrangement with John Wiley & Sons) ((en))

Gender-age differences in hiring rates and prospective wages: Evidence from job referrals to unemployed workers (2023)

Abstract
"This paper uses matched worker-vacancy data to study gender differences in hiring outcomes of jobseekers in Austria. When registered at the public employment office, jobseekers are assigned caseworkers who refer them to suitable vacancies. Our findings show that female and male jobseekers are equally likely to get hired via such a referral, but it takes women longer to get a job offer. Most of the observed gender differences stem from younger jobseekers (below age 35) and are explained by rejections of employers. Young women are also less often hired for better-paying jobs. We argue that these differences are consistent with hiring discrimination against women in their fertile age. Our analysis shows that young female jobseekers are much more likely to go on parental leave in the future, while men almost never take extended parental leave. Consistent with this hypothesis, we find that hiring differences are larger for jobs associated with higher replacement costs and smaller in tight labor markets."

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
"We provide insights on how job search changed in the Covid-19-crisis by analyzing data from the LinkedIn professional network for Germany. We find that competition among workers for jobs strongly increased – which is due to additional job seekers rather than higher search intensity. Furthermore, the LinkedIn data show that people from industries particularly affected by the crisis applied much more frequently and there had been a substantial shift in the target industries for applications. Finally, we find that at the onset of the Covid-19-crises applications were made significantly more often below and significantly less often above a person’s level of seniority."

Abstract
"We design a survey that asks firms about the obstacles that discourage them from hiring despite having potential needs. Using Danish administrative data and subjective beliefs elicited from our survey, we show how hiring obstacles vary across firms. Over two-thirds of employers agree that skill shortages are a hiring obstacle. One-third of employers consider labor costs, the time to find candidates, and the time to train new recruits as hiring obstacles. High-wage firms are less discouraged by labor costs, while younger or smaller firms are more discouraged by search and training time. Around thirty percent of employers prefer to hire the already employed over the unemployed because they believe that unemployed workers have lower abilities due to negative selection or skill depreciation during unemployment. Firms with such preferences are more likely to report hiring obstacles." (Author's abstract, IAB-Doku) ((en))

Abstract
"In diesem Aufsatz stellen wir ein Arbeitsnachfrage-Modell auf, das Einstellungskosten berücksichtigt, die aufgrund eines angespannten Arbeitsmarktes bei der Besetzung offener Stellen anfallen. Darauf aufbauend schätzen wir den Effekt der Arbeitsmarktanspannung auf die betriebliche Arbeitsnachfrage, indem wir neuartige Bartik-Instrumente sowie administrative Beschäftigungsdaten für Deutschland heranziehen. Im Einklang mit der Theorie deuten die IV-Ergebnisse darauf hin, dass ein zehnprozentiger Anstieg der Arbeitsmarktanspannung die betriebliche Beschäftigung um rund 0,5 Prozent reduziert. Außerdem zeigt sich, dass die betriebliche Lohnelastizität der Arbeitsnachfrage durch Einbeziehung von Suchexternalitäten auf der aggregierten Ebene von -0,7 auf -0,5 sinkt. In Bezug auf die Einführung des gesetzlichen Mindestlohns im Jahr 2015 implizieren die Elastizitäten nur geringfügig negative Beschäftigungseffekte, was die Ergebnisse empirischer Ex-Post-Evaluationen widerspiegelt. Darüber hinaus führte die Verdoppelung der Arbeitsmarktanspannung in Deutschland zwischen 2012 und 2019 zu einer Verringerung des Beschäftigungswachstums um rund 1,1 Millionen Arbeitsplätze."

Demand for Personality Traits, Tasks, and Sorting (2023)

Brencic, Vera & Andrew McGee (2023): Demand for Personality Traits, Tasks, and Sorting. (IZA discussion paper / Forschungsinstitut zur Zukunft der Arbeit 16576), Bonn, 69 S.
Abstract
"In job ads, employers express demand for personality traits when seeking workers to perform tasks that can be completed with different behaviors (e.g., communication, problem-solving) but not when seeking workers to perform tasks involving narrowly prescribed sets of behaviors such as routine and mathematics tasks. For many tasks, employers appear to demand narrower personality traits than those measured at the Big Five factor level. The job ads also exhibit substantial heterogeneity within occupations in the tasks mentioned. Workers may thus sort based on personality-derived comparative advantages in tasks into jobs rather than occupations. In the National Longitudinal Survey of Youth 1997, we confirm that personality sorting based on tasks occurs at both the occupation and job levels. In this sample, however, there is little evidence of task-specific wage returns to personality traits, which would influence the supply of traits to jobs with particular tasks. This may explain why personality sorting based on tasks in the sample is very limited in spite of the correlations between tasks and employers' demands for traits."

Abstract
"The hiring and recruitment process is one of the main challenges to the success of companies and a significant driver of total labor costs. We use representative employer data for German private-sector establishments with at least 50 employees to explore recent developments in employer search, selection, and screening activities over the years of 2012–2018. We document changes in hiring policies over time and address heterogeneity across establishments related to size, ownership, and industry sector. Our results show that although establishment characteristics are correlated with different facets of hiring behavior, there is no homogeneous pattern for employer search and selection instruments. We highlight differences of hiring practices targeted at managerial versus non-managerial new hires. Finally, we outline potential mechanisms and research gaps for future work and discuss managerial implications." (Author's abstract, IAB-Doku, © SAGE) ((en))

Abstract
"We propose that new firm founders locate their firms close to their home region in order to hire workers they know about through their prior employment, since it is easier to find high productivity employees among talent pools for which you have significant personal experience. We test our proposition using a matched employer–employee dataset for Portugal. Consistent with our predictions, new firms in the same industry as their founder's prior employer (i.e., spinoffs) are more likely to locate in their founder's home region, to hire workers from the founder's prior employer and other firms in the same region and industry, to employ them longer, and to perform better than other new firms. Results suggest that the agglomeration of high performing spinoffs next to their parent firms should facilitate the emergence of successful industrial clusters."

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
"Firms and workers predominately match via job postings, networks of personal contacts or the public employment agency, all of which help to ameliorate labor market frictions. In this paper we investigate the extent to which these search channels have differential effects on labor market outcomes. Using novel linked survey-administrative data we document that (i) low-wage firms and low-wage workers are more likely to match via networks or the public agency, while high-wage firms and high-wage workers succeed more often via job postings; (ii) job postings help firms the most in poaching and attracting high-wage workers and help workers the most in climbing the job ladder. To evaluate the implications of these findings for employment, wages and labor market sorting, we structurally estimate an equilibrium job ladder model featuring two-sided heterogeneity, multiple search channels and endogenous recruitment effort. The estimation reveals that networks are the most cost-effective channel, allowing firms to hire quickly, yet attracting workers of lower average ability. Job postings are the most costly channel, facilitate hiring workers of higher ability, and matter most for worker-firm sorting. Although the public employment agency provides the lowest hiring probability, its removal has sizeable consequences, with aggregate employment declining by at least 1.4 percent and rising bottom wage inequality."

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."
