Understanding boundary conditions, or situations when relations between variables change depending on values of other variables, is critical for theory advancement and for providing guidance for practice. Metaregression is ideally suited to investigate boundary conditions because it provides information on the presence and strength of such conditions. In spite of its potential, results of our review of 63 metaregression articles published in

Employee ownership has been an area of significant practitioner and academic interest for the past four decades. Yet, empirical results on the relationship between employee ownership and firm performance remain mixed. To aggregate findings and provide potential direction for future theoretical development, we conducted a meta‐analysis of 102 samples representing 56,984 firms. Employee ownership has a small, but positive and statistically significant relation to firm performance ( truer¯ = 0.04). The effect is generally positive for studies with different sampling designs (samples assessing change in performance pre‐employee–post‐employee ownership adoption or samples on firms with employee ownership), different performance operationalisation (efficiency or growth) and firm type (publicly held or privately held). Suggesting benefits of employee ownership in a variety of contexts, we found no differences in effects on performance in publicly held versus privately held firms, stock or stock option‐based ownership plans or differences in effects across different firm sizes (i.e. number of employees). We do find that the effect of employee ownership on performance has increased in studies over time and that studies with samples from outside the USA report stronger effects than those within. We also find little to no evidence of publication bias.

The HEXACO model presents a conceptualization of personality that includes the trait honesty-humility (H-H) in addition to 5 other personality traits (i.e., agreeableness, conscientiousness, emotionality, extraversion, openness) that closely approximate the ubiquitous five-factor model (FFM) of personality. A substantial literature has accumulated supporting the structure of the HEXACO model and the construct validity of the H-H trait in particular. A newer development is the appearance of H-H in the applied psychology literature. This begs the question of whether H-H exhibits significant criterion-related validity with respect to job performance and whether H-H accounts for incremental validity over other established individual differences predictors of job performance. Accordingly, the purpose of this study is to conduct a meta-analysis of the relationship between H-H and 3 major dimensions of job performance (counterproductive work behavior [CWB], organizational citizenship behavior [OCB], and task performance) and compare the incremental validity of H-H with other established individual differences predictors (general mental ability, the FFM, and integrity tests). Our results indicate that H-H correlates −.44 with CWB, .13 with OCB, and .15 with task performance (each correlation corrected for unreliability in both the independent and dependent variables). Further, H-H demonstrated incremental validity over the other individual differences predictors in the case of CWB but not OCB and task performance.

Although one of the most well-established research findings in industrial-organizational psychology is that general mental ability (GMA) is a strong and generalizable predictor of job performance, this meta-analytically derived conclusion is based largely on measures of task or overall performance. The primary purpose of this study is to address a void in the research literature by conducting a meta-analysis to determine the direction and magnitude of the correlation of GMA with 2 dimensions of nontask performance: counterproductive work behaviors (CWB) and organizational citizenship behaviors (OCB). Overall, the results show that the true-score correlation between GMA and CWB is essentially 0 (-.02, k = 35), although rating source of CWB moderates this relationship. The true-score correlation between GMA and OCB is positive but modest in magnitude (.23, k = 43). The 2nd purpose of this study is to conduct meta-analytic relative weight analyses to determine the relative importance of GMA and the five-factor model (FFM) of personality traits in predicting nontask and task performance criteria. Results indicate that, collectively, the FFM traits are substantially more important for CWB than GMA, that the FFM traits are roughly equal in importance to GMA for OCB, and that GMA is substantially more important for task and overall job performance than the FFM traits. Implications of these findings for the development of optimal selection systems and the development of comprehensive theories of job performance are discussed along with study limitation and future research directions.
