Resampling methods are used to calculate confidence limits in a meta-analysis of the association between unions and productivity for the population of U.S. studies. The available evidence points to a positive and statistically significant association between unions and productivity in the U.S....

The impact of employee relations on performance has received much attention. Theory predicts that employee relations will impact on efficiency as well as productivity, yet researchers usually assume a production process that is fully efficient. In this paper, the stochastic production frontier...

The effect of unions on profits continues to be an unresolved empirical issue. In this paper, meta-regression analysis is applied to the population of 45 econometric studies that report 532 estimates of the direct effect of unions on profits. We show that unions have a significant negative...

The impact of unions on productivity growth has received extensive attention from researchers in industrial relations and economics. Despite a voluminous literature, controversy continues regarding the effect of unions on productivity growth. In this paper, meta-analysis and meta-regression...

A number of conflicting theoretical hypotheses have been advanced regarding the impact of unions on investment behavior. The net impact of unions on investment is thus an empirical issue. In this paper the available empirical literature is reviewed. In addition, new evidence of the impact of...

Publication bias arises when statistically non-significant results are suppressed or when only results satisfying prior expectations are published. Like most fields, research in industrial relations is vulnerable to publication bias. In this paper, qualitative and quantitative techniques are...

The impact of unions on profitability is investigated through a comprehensive meta-analysis and meta-regression analysis of the available literature. Drawing upon 57 published empirical studies, with 91,200 observations, the paper establishes a negative and statistically significant union-profit...

The effect of unions on profits continues to be an unresolved theoretical and empirical issue. In this paper, clustered data analysis and hierarchical linear meta-regression models are applied to the population of forty-five econometric studies that report 532 estimates of the direct effect of...

There is currently no consensus regarding the effect of unions on technology. We apply meta-regression analysis to the extant econometric studies and find that unions depress investment in new technology. However, this adverse effect has been declining over time and is moderated by country...
