... By analyzing soccer players, we also contribute to a large body of economic research, which has frequently applied sports data to uncover otherwise hidden economic mechanisms ( Bar-Eli et al., 2020 ). Among others, this concerns the testing of theoretical hypotheses from game theory (e.g., Bhaskar, 2008;Chiappori et al., 2002;Kassis et al., 2021 ), identifying psychological drivers of cognitive performance (e.g., Apesteguia and Palacios-Huerta, 2010;González-Díaz and Palacios-Huerta, 2016 ), or deriving conclusions for public and labor economics (e.g., Caselli et al., 2022;Kahn and Sherer, 1988;Kleven et al., 2013;Lichter et al., 2017;Parsons et al., 2011;Principe and van Ours, 2022 ). ...

... In general, workers in smaller companies have a greater risk for accidents and injuries at the workplace [16,17]. Temporary employees are generally at higher risk of an accident [16][17][18]. In this study, temporary workers were involved in 17% of the accidents. ...

... Finally, moderator analyses will provide information about the robustness of the findings, by testing whether rank-order stability differs across sample and methodological characteristics. It is important to note that some potentially relevant moderators could not be examined in this meta-analysis, such as personality variables, socioeconomic status, and sexual orientation (Chen & van Ours, 2018;Conger et al., 2010;Karney & Bradbury, 1995). The reason is that (a) information on the characteristics was not reported in most primary studies (i.e., personality variables), (b) the information that was available was not comparable across most primary studies (i.e., socioeconomic status), or (c) the very low number of samples that provided information on the characteristic would not have allowed for reliable conclusions (i.e., sexual orientation). ...

... However, assuming an immediate and constant response to MEL, might lead to misspecification. In Panel B, I include indicator variables for year of exposure (1-2 years, 3-6 years, and 7 or more years of the policy phase) to allow for a more flexible, non-linear response to the legislation (Chen & van Ours, 2022). These estimates support that the effects are not constant over time, but the longer a state has implemented a same-sex marriage law, the higher the health benefits. ...

... Rather than excluding unpartnered individuals, for whom our rubric does not allow for sexual orientation to be classified, the results of Table 10 repeat the analysis with these individuals included and regarded as heterosexuals (along the same lines as Chen & Van Ours, 2021). This has the advantage of increasing sample sizes and extending across partnered and unpartnered individuals, but this reclassification in itself is likely to misclassify some sexual minorities. ...

... Because poor health is particularly common among the elderly, old age is sometimes considered a critical risk factor for loneliness. However, although studies conducted before the COVID-19 pandemic found that average loneliness was highest in the oldest age group (80 years and older) 18,[21][22][23] , increased loneliness has also been reported in younger age groups 18,24 , and a meta-analysis of longitudinal studies found no significant relationship between age and loneliness 25 . Identifying with a group that is marginalized within a society (for example, ethnic/racial 26,27 or sexual orientation/identity 28-31 minority groups) is associated with higher average levels of loneliness, presumably because these groups are more likely to experience stressors such as discrimination or rejection, which increase the risk of loneliness [29][30][31][32][33] . ...

... cionados se deduce que las experiencias de victimización no son las mismas para todas las PsSH. En este sentido, las diferencias asociadas a la edad, el género, el origen o la situación residencial, y el impacto interseccional entre las mismas, adquieren una relevancia fundamental (Moschion & van Ours, 2021). Como consecuencia, destaca la importancia de la interseccionalidad como elemento clave del análisis de la realidad que afecta a las PsSH y a sus trayectorias de violencia y discriminación. ...

... There is a wealth of research that examines the factors that influence performance in professional football (Peeters & van Ours, 2021;Van Ours & Van Tuijl, 2016;Wilson et al., 2018). Yet, we still do not have a comprehensive understanding of how participating in pan-European competitions, such as the UEFA Champions League (CL), or UEFA Europa League (EL) impacts domestic performance. ...

... it provides a wide range of benefits to same-sex couples. Examples of those benefits are access to partner's health coverage (Gonzales, 2014;Carpenter, Eppink, Jr., & Mckay, 2021), improved mental health (Teo, Metheny, & Chum, 2021), health (Ogolsky, Monk, Rice, & Oswald, 2019), partnership stability (Chen & Ours, 2020;Kennedy & Dalla, 2020), and the rights to adopt children (LGBT parenting) (Takacs, Szalma, & Bartus, 2016). ...

... Contrary to the above, a growing body of research focuses on problem behaviors or anti-social behaviors (ASB) among young people (Basen-Engquist et al., 1996;Childs et al., 2011;Childs & Sullivan, 2013;Chun & Mobley, 2010;Dembo et al., 2010;Hair et al., 2009;Ward et al., 2021). Research on risk and protective factors for problem behaviors among young people holds that youth is characteristically a time of problematic behavior (C. . ...
