Biewen, Martin & Pascal Erhardt (2025): Using post-regularization distribution regression to measure the effects of a minimum wage on hourly wages, hours worked and monthly earnings. In: The econometrics journal. DOI:10.1093/ectj/utaf014

Abstract

"We evaluate the distributional effects of a minimum wage introduction based on a data set with a moderate sample size but a large number of potential covariates. In this context, the selection of relevant control variables at each distributional threshold is crucial to test hypotheses about the impact of the continuous treatment variable. To this end, we use the post-double selection logistic distribution regression approach proposed by Belloni et al. (2018a), which allows for uniformly valid inference about the target coefficients of our low-dimensional treatment variables across the entire outcome distribution. Our empirical results show that the minimum wage replaced hourly wages below the minimum threshold, increased monthly earnings in the lower-middle segment but not at the very bottom of the distribution, and did not significantly affect the distribution of working hours."

Clemens, Jeffrey & Michael Strain (2025): The Heterogeneous Effects of Large and Small Minimum Wage Changes: Evidence Using a Partially Pre-Committed Analysis Plan. In: Journal of labor economics. DOI:10.1086/736552

Abstract

"This paper advances the use of partially pre-committed analysis plans in non-experimental research settings. In a study of recent minimum wage changes, we demonstrate how analyses of longer-run impacts of policy interventions can be pre-specified as extensions to very short-run analyses. Further, our pre-analysis plan includes comparisons of the effects of large vs.small minimum wage increases, which is a theoretically motivated dimension of heterogeneity. We discuss how these use cases harness the strengths of pre-analysis planswhile mitigating their weaknesses. This project’s initial analyses explored CPS and ACS datafrom 2011 through 2015. Alongside these analyses, we pre-committed to analyses in corporating CPS and ACS data extending through 2019. Averaging across the specifications in our pre-analysis plan, we estimate that relatively large minimum wage increases reduced employment rates among individuals with low levels of experience and education by just over 2 and a half percentage points during the decade prior to the onset ofthe Covid-19 pandemic. Our estimates of the effects of relatively small minimum wage increases vary across data sets and specifications but are, on average, both economically andstatistically indistinguishable from zero. We estimate that the elasticity of employment with respect to the minimum wage is substantially more negative for large minimum wage increases than for small increases."

Abstract

"This paper investigates how labor-market tightness affects market outcomes if firms use informal, self-enforcing, agreements to motivate workers. We characterize profit-maximising equilibria and show that an increase in the supply of homogeneous workers can increase wages. Moreover, even though all workers are identical in terms of skills or productivity, profit-maximising discrimination equilibria exist. There, a group of majority workers is paid higher wages than a group of minority workers, who may even be completely excluded. Minimum wages can reduce such discrimination and increase employment. We discuss how these results relate to empirical evidence on downward wage rigidity, immigration, the gender pay gap, and credentialism." (Author's abstract, IAB-Doku) ((en))

Abstract

"Diese Studie untersucht die Auswirkungen der Einführung des gesetzlichen Mindestlohns in Deutschland auf Stundenlöhne, Monatslöhne und bezahlte Arbeitszeiten. Es wird ein auf der Verdienststrukturerhebung (VSE) 2014 und der Verdiensterhebung (VSE) 2015 basierender Paneldatensatz genutzt und ein Differenz-in-Differenzen-Ansatz auf Betriebsebene angewendet. Die Vorteile und Grenzen dieses Ansatzes werden im Vergleich zu früheren Studien erörtert. Die Ergebnisse deuten auf einen Effekt der Einführung des gesetzlichen Mindestlohns auf die Stundenlöhne von etwa 13 Prozent hin. Aufgrund negativer Effekte auf die Arbeitszeit von etwa minus 6 Prozent sind die Auswirkungen auf den monatlichen Bruttoverdienst geringer, betragen aber immer noch etwa 8 Prozent. Der Mindestlohn hat vor allem bei Geringverdienern in Teilzeitbeschäftigung und in Ostdeutschland zu einer Erhöhung der Monatslöhne geführt. Damit werden neue Erkenntnisse zur Debatte über die Existenz und das Ausmaß von Mindestlohneffekten auf Verdienste und Arbeitszeiten sowie zu deren politischen Implikationen vorgelegt."

Abstract

"This article examines the effects of the introduction of the statutory minimum wage on the distribution of individual income from wages, as well as gross and net means-weighted income of workers in Germany. For the first time, data from the Survey of Income and Consumption was used, in which incomes are recorded in great detail. Both descriptive findings and the results of Unconditional Quantile Regressions indicate that the incomes of workers in regions with a high level of minimum wage intervention experienced significant increases after the introduction of the minimum wage, ranging into the middle band of the income distribution. Accordingly, the minimum wage has positively influenced the incomes of a large number of employee households." (Author's abstract, IAB-Doku, © De Gruyter) ((en))

Abstract

"This paper examines the impact of unions on unemployment and wages in a dynamic equilibrium search model. We model a union as imposing a minimum wage and rationing jobs to ensure that the union's most senior members are employed. This generates rest unemployment, where following a downturn in their labor market, unionized workers are willing to wait for jobs to reappear rather than search for a new labor market. We characterize the hazard rate of exiting unemployment, and show that it is low at long durations whenever the union-imposed minimum wage is high; we establish that a high union-imposed minimum wage generates a compressed wage distribution and a high turnover rate of jobs —properties consistent with the data. Finally, we show that seniority rules lead to lower unemployment levels, relative to an alternative rule allocating jobs to workers randomly." (Author's abstract, IAB-Doku, © 2024 Elsevier) ((en))

Abstract

"The authors estimate the effects of an increase in the youth minimum wage in the Netherlands on low-paid workers’ employment and earnings, using a difference-in-differences approach with detailed administrative data. Findings show that the increase does not have a negative effect on the number of jobs or hours worked, hence raising overall earnings for affected workers. Further, the minimum wage increase has substantial spillover effects, accounting for close to 70% of the average wage increase experienced by workers. While employment grows in fixed-term and temporary help agency contracts, the authors do not find evidence of declines in employment in other types of work arrangements, nor of labor-labor substitution. Labor market outcomes evolve most favorably for full-time incumbent workers who are not enrolled in education and are thus less likely to be transient occupants of minimum wage jobs."

Abstract

"We structurally estimate an equilibrium search model using German administrative data and use the model for counterfactual analyses of a uniform minimum wage. The model with worker and firm heterogeneity does not restrict the sign of employment effects a priori; it allows for different job offer arrival rates for the employed and the unemployed and lets firms optimally choose their recruiting intensity. We find that unemployment is a non-monotonic function of the minimum wage level. Effects differ strongly by labor market segment defined by region, skill, and permanent worker ability."

Dörsam, Michael & Henrika Langen (2024): Minimum Wages in the Apprenticeship Market: Adverse Effects on Labor Demand? (Working paper / Swiss Leading House 234), Zürich, 38 S.

Abstract

"To increase the attractiveness of vocational education and training and secure a sufficient supply of skilled labor, the German government introduced a statutory minimum wage for apprenticeship contracts. As of January 1, 2020, apprentices starting an apprenticeship that year became entitled to an annually increasing minimum wage. Merging apprenticeship posting data from the Federal Employment Agency with administrative data on apprenticeship contracts, we investigate the causal effect of this minimum wage legislation on labor demand. Exploiting regional and occupational variation in the share of apprenticeships paid at the minimum wage level, we estimate a standard difference-in-differences, a triple difference, and a synthetic difference-in-differences model. Our estimates suggest that the introduction of the minimum wage had no significant effect on the overall number of apprenticeship postings in low-wage occupations in districts with a high prevalence of minimum wage contracts. However, when examining the minimum wage effect in selected low-wage occupations separately, we find substantial differences with no observable impact on health and wellness apprenticeships but a substantial reduction in apprenticeship postings in various low-wage production and manufacturing occupations."

Abstract

"We examine whether the effects of the introduction of a minimum wage on low-pay employment duration in Germany in 2015 are heterogeneous by gender. In order to disentangle the effects on women and men, we estimate a duration model with unobserved heterogeneity in which we allow gender differences and differences before and after the introduction of the minimum wage. We find that the reform does affect women and men differently, in particular, it mainly increases men’s job attachment. These gender differences in job attachment are the strongest for full-time employment. In consequence, although the minimum wage may have been set up as a gender-neutral instrument, in an indirect way, it affects women and men differently. We discuss different mechanisms that could account for our result and carry out several robustness checks." (Author's abstract, IAB-Doku, © De Gruyter) ((en))

Davon waren anteilig weniger Betriebe und Beschäftigte betroffen als bei der letzten - deutlich stärkeren - Anhebung von 10,45 auf 12,00 Euro. Besonders stark waren die Auswirkungen, wie schon in den vergangenen Jahren, im Gastgewerbe sowie in der Nahrungs- und Genussmittelbranche. Dort profitierten rund 45 beziehungsweise 30 Prozent der Beschäftigten unmittelbar von der jüngsten Erhöhung." (Autorenreferat, IAB-Doku)

Abstract

"We assess the impact of nationwide minimum wages on employment throughout the whole wage distribution by exploiting geographical variation in the level of wages. We find a substantial increase in wages at the bottom of the wage distribution, while we detect a small, statistically insignificant negative effect on employment. Combining the estimated change in the wage distribution with a tax and benefit microsimulation model, we show that the minimum wage generates considerable proportional income gains up to the middle of the household income distribution."

Abstract

"This paper provides comprehensive evidence on the labor and product market effects of a high-impact minimum wage introduction in the highly competitive hairdressing sector. Using detailed administrative data, I find negligible overall employment effects, even though the minimum wage substantially increased hourly wages. However, sub-group analyses reveal considerable heterogeneity in the estimated employment effects and suggest shifts away from marginal towards regular employment. Analyses of the price effects suggest that the reform increased output prices considerably, implying that consumers largely paid for the minimum wage."

Abstract

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

Abstract

"Der Mindestlohn hat bei Frauen seit seiner Einführung zu stärkeren Anstiegen der durchschnittlichen Stundenlöhne und monatlichen Verdienste geführt als bei Männern. Die Auswirkungen des Mindestlohns auf die Stundenlöhne der vom Mindestlohn betroffenen Frauen und Männern fielen im Durchschnitt ähnlich hoch aus. Frauen sind jedoch häufiger im Mindestlohnbereich beschäftigt als Männer und profitieren somit häufiger von diesem. Ergebnisse zu geschlechterspezifischen Reduzierungen der Arbeitszeit aufgrund des Mindestlohns fallen unterschiedlich aus. Weder bei Frauen, noch bei Männern kam es zu erheblichen Beschäftigungseffekten des Mindestlohns. Der Mindestlohn trägt somit zur Reduzierung der Entgeltungleichheit nach Geschlecht bei."

Abstract

"Minimum wages are increasingly discussed as an instrument against (in-work) poverty and income inequality in Europe. Just recently the German government opted for a substantial ad-hoc increase of the minimum-wage level to €12 per hour mentioning poverty prevention as an explicit goal. We use the introduction of the federal minimum wage in Germany in 2015 to study its redistributive impact on disposable household incomes. Based on the German Socio-Economic Panel we analyse changes in poverty and income inequality investigating different mechanisms of the transmission from individual gross wage-rates to disposable household incomes. We find that the minimum wage is an inadequate tool for income redistribution because it does not target poor households. Individuals affected by the minimum wage are not primarily in households at the bottom of the income distribution but are spread across it. Consequently, welfare dependence decreases only marginally. The withdrawal of transfers or employment effects cannot explain the limited effect on poverty. Complementary simulations show that neither full compliance nor a markedly higher level of €12 per hour can render the minimum wage more effective in reducing poverty."

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."
