In recent decades, researchers have found compelling evidence of discrimination in the labor and housing market toward ethnic minorities based on field experiments using fictitious applications. However, these findings may be exaggerated as the names used for ethnic minorities in various experiments may have also signaled low socioeconomic class. Therefore, in this study, we perform a name categorization experiment in the United States that yields 56 names associated with six ethnicity groups, which signal different ethnicities and genders but similar social classes. These names should greatly improve the validity of future experiments on ethnic discrimination.

This article contributes to the nascent literature on the effect of grade retention in school on later labour market success. A field experiment is conducted to rule out the endogeneity of both outcomes. More concretely, various treatments of grade retention are randomly assigned to fictitious résumés sent in application to real vacancies. Overall, grade retention does not significantly affect positive call-back by employers. However, when narrowing in on vacancies for occupations where on-the-job training is important, job candidates with a record of grade retention are 16% less likely to receive a positive reaction. This finding is consistent with Queuing theory.

Research exploiting data on classic (offline) couple formation has confirmed predictions from evolutionary psychology in a sense that males attach more value to attractiveness and women attach more value to earnings potential. We examine whether these human partner preferences survive in a context of fewer search and social frictions. We do this by means of a field experiment on the mobile dating app Tinder, which takes a central place in contemporary couple formation. Thirty-two fictitious Tinder profiles that randomly differ in job status and job prestige are evaluated by 4,800 other, real users. We find that both males and females do not use job status or job prestige as a determinant of whom to show initial interest in on Tinder. However, we do see evidence that, after this initial phase, males less frequently begin a conversation with females when those females are unemployed but also then do not care about the particular job prestige of employed females.

Internships during tertiary education have become substantially more common over the past decades in many industrialised countries. This study examines the impact of a voluntary intra-curricular internship experience during university studies on the probability of being invited to a job interview. To estimate a causal relationship, we conducted a randomised field experiment in which we sent 1,248 fictitious, but realistic, resumes to real job openings. We find that applicants with internship experience have, on average, a 12.6% higher probability of being invited to a job interview.

We investigated the impact on first hiring outcomes of two main curriculum vitae (CV) characteristics by which graduates with a tertiary education degree distinguish themselves from their peers: degree class and extra-curricular activities. These characteristics were randomly assigned to 2,800 fictitious job applications that were sent to real vacancies in Belgium. Academic performance and extra-curricular engagement both enhanced job interview rates by about 7%. The effect of a higher degree class was driven by female (versus male) candidates and candidates with a master’s (versus a bachelor’s) degree. We did not find evidence for these CV characteristics to be substitutes or to reinforce each other’s effect.

In this study, we examine the impact of an individual’s education level on her/his mating success by means of a field experiment on the mobile dating app Tinder, using a sample of 3,600 profile evaluations. In line with previous studies from the field of evolutionary psychology, our results indicate a heterogeneous effect of education level by gender: while females strongly prefer a highly educated potential partner, we cannot accept this hypothesis for males. Additionally, in contrast with previous literature on partner choice in an offline context and on classic online dating websites, we do not find any evidence for educational assortative mating, i.e. preferring a partner with a similar education level, on mobile dating apps such as Tinder. We argue that this is due to our research design, which allows us to examine actual (instead of stated) mate preferences in a dating market without search frictions and social frictions.

This chapter aims to provide an exhaustive list of all (i.e. 90) correspondence studies on hiring discrimination that were conducted between 2005 and 2016 (and could be found through a systematic search). For all these studies, the direction of the estimated treatment effects is tabulated. In addition, a discussion of the findings by discrimination ground is provided.

We investigate whether, why and when prosocial engagement has a causal effect on individual employment opportunities. To this end, a field experiment is conducted in which volunteering activities are randomly assigned to fictitious job applications sent to genuine vacancies. We find that volunteers get one third more interview invitations than non‐volunteers. The volunteering premium is higher for females but invariant with respect to the number of engagements and the private versus public or nonprofit orientation of the job posting firm. As a result, our findings are consistent with the idea that prosocial workers sort themselves into non‐commercial sectors.

Correspondence studies are nowadays viewed as the most compelling avenue to test for hiring discrimination. However, these studies suffer from one fundamental methodological problem, as formulated by Heckman and Siegelman (The Urban Institute audit studies: Their methods and findings. In M. Fix, and R. Struyk (Eds.), Clear and convincing evidence: Measurement of discrimination in America, 1993), namely the bias in their results in case of group differences in the variance of unobserved determinants of hiring outcomes. In this study, the authors empirically investigate this bias in the context of gender discrimination. They do not find significant evidence for the predicted bias.

This study presents a new field experimental approach for measuring age discrimination in hiring. In addition to the classical approach in which candidates' ages are randomly assigned within pairs of fictitious resumes that are sent to real vacancies, we randomly assign activities undertaken by the older candidates during their additional life years between these pairs. When applying this design to the Belgium case, we find that age discrimination is fundamentally heterogeneous by older candidates' career pattern. Older age affects call-back only (negatively) in case older candidates were inactive or employed in an out-of-field job during their additional post-educational years.

We investigate the impact of student work experience on later hiring chances. To completely rule out potential endogeneity, we present a field experiment in which various forms of student work experience are randomly disclosed by more than 1000 fictitious graduates applying for jobs in Belgium. Theoretical mechanisms are investigated by estimating heterogeneous treatment effects by the relevance and timing of revealed student work experience. We find that neither form of student work experience enhances initial recruitment decisions. For a number of candidate subgroups (by education level and occupation type), even an adverse effect is found.

We investigate whether the publicly available information on Facebook about job applicants affects employers' hiring decisions. To this end, we conduct a field experiment in which fictitious job applications are sent to real job openings in Belgium. The only characteristic in which these candidates differ is the unique Facebook profile that can be found online with their name. Candidates with the most beneficial Facebook picture obtain approximately 39% more job interview invitations compared to candidates with the least beneficial picture. In addition, we find suggestive evidence for a higher effect of Facebook profile picture appearance on hiring chances when candidates are highly educated and when recruiters are female.

We investigate the importance of employer preferences in explaining Sticky Floors, the pattern that women are, compared to men, less likely to start to climb the job ladder. To this end we perform a randomised field experiment in the Belgian labour market and test whether hiring discrimination based on gender is heterogeneous by the promotion characteristics of the selected jobs. We find that women get 33% less interview invitations when they apply for jobs implying a first promotion in functional level. On the other hand, their hiring chances are not significantly affected by the job authority level of the job.

We study the causal impact of revealing pro-unionism during the recruitment stage on hiring chances. To this end, we conduct a randomised field experiment in the Belgian labour market. When matched with employer and sector data, the experimentally gathered data enable us to test the heterogeneity of discrimination against pro-union applicants by the union density in the sector and the size of the firm. We find that disclosure of pro-unionism affects hiring chances in a negative way and that – in line with our expectations based on the literature – this negative impact is stronger in highly unionised sectors.

This study aims at estimating the stigma effect of unemployment and overeducation within one framework. To this end, we conduct a field experiment in the Belgian labour market. We send out trios of fictitious male job applications to real vacancies. These applications differ only by the labour market history of the candidates. By monitoring the subsequent reactions from the employer side, we find evidence for a larger stigma effect of unemployment than overeducation. The stigma effect of overeducation is found to occur for permanent contract jobs but not temporary ones.

This study assesses hiring discrimination based on disclosed depression. We send out pairs of job applications from fictitious unemployed candidates to real vacancies in Belgium. Within each pair, one candidate cites depression as the reason for her/his unemployment, whereas the other candidate reveals no reason for unemployment. Overall, the hypothesis that applicants disclosing former depression are treated unfavourably is rejected. However, if we break up the data by the gender of the recruiter, we see that revealing former depression as a reason for unemployment is rewarded by female recruiters, whereas it affects the hiring decisions made by male recruiters in a non-positive way.

We identify hiring discrimination against former juvenile delinquents in a direct way. To this end we conduct a field experiment in the Belgian labour market. We find that labour market discrimination is indeed a major barrier in the transition to work for former juvenile delinquents. Labour market entrants disclosing a history of juvenile delinquency get about 22 percent less callback compared to their counterparts without a criminal record. This discrimination is more outspoken among the low-educated.

We empirically test the relationship between hiring discrimination and labour market tightness at the level of the occupation. To this end, we conduct a correspondence test in the youth labour market. In line with theoretical expectations, we find that, compared to natives, candidates with a foreign sounding name are equally often invited to a job interview if they apply for occupations for which vacancies are difficult to fill, but they have to send twice as many applications for occupations for which labour market tightness is low. Our findings are robust against various sensitivity checks.

This study directly assesses the impact of military work experience compared with civilian work experience in similar jobs on the subsequent chances of being hired in the civilian labour market. It does so through a field experiment in the Belgian labour market. A statistical examination of our experimental dataset shows that in general we cannot reject that employers are indifferent to whether job candidates gained their experience in a civilian or a military environment.
