"The employment effect from raising the minimum wage has long been studied but remains in dispute. Our meta-analysis of 236 estimated minimum wage elasticities and 710 partial correlation coefficients from 16 UK studies finds no overall practically significant adverse employment effect. Unlike US studies, there seems to be little, if any, overall reporting bias. Multivariate meta-regression analysis identifies several research dimensions that are associated with differential employment effects. In particular, the residential home care industry may exhibit a genuinely adverse employment effect."

"Richard B. Freeman and James L. Medoff's now classic 1984 book What do unions do? stimulated an enormous theoretical and empirical literature on the economic impact of trade unions. Trade unions continue to be a significant feature of many labour markets, particularly in developing countries, and issues of labour market regulations and labour institutions remain critically important to researchers and policy makers.

The relations between unions and management can range between cooperation and conflict; unions have powerful offsetting wage and non-wage effects that economists and other social scientists have long debated. Do the benefits of unionism exceed the costs to the economy and society writ large, or do the costs exceed the benefits? The Economics of Trade Unions offers the first comprehensive review, analysis and evaluation of the empirical literature on the microeconomic effects of trade unions. The book applies the tools of meta-regression analysis to identify and quantify the economic impact of trade unions, as well as to correct research design faults, the effects of sample selection and model misspecification.

This volume makes use of a unique dataset of hundreds of empirical studies and their reported estimates of the microeconomic impact of trade unions. Written by three authors who have been at the forefront of this research field (including the co-author of the original volume, What do unions do?), this book offers an overview of a subject that is of huge importance to scholars of labour economics, industrial and employee relations, and human resource management, as well as those with an interest in meta-analysis."

"This paper develops and applies several meta-analytic techniques to investigate the presence of publication bias in industrial relations research, specifically in the union-productivity effects literature. Publication bias arises when statistically insignificant results are suppressed or when results satisfying prior expectations are given preference. Like most fields, research in industrial relations is vulnerable to publication bias. Unlike other fields such as economics, there is no evidence of publication bias in the union-productivity literature, as a whole. However, there are pockets of publication selection, as well as negative autoregression, confirming the controversial nature of this area of research. Meta-regression analysis reveals evidence of publication bias (or selection) among U.S. studies."

" This article is the second in a series to celebrate the 70th anniversary of the ILR Review. The series features articles that analyze the state of research and future directions for important themes this journal has featured over many years of publication.

In this article, the authors assess the credibility of research that has tested the theoretical contests between the monopoly and the collective voice model of unions developed by Freeman and Medoff in What Do Unions Do? The authors go beyond prior analyses by examining more than 2,000 estimates that consider the effects of unions on a broad range of organizational and individual outcomes, including productivity, productivity growth, capital investment, profits, and job satisfaction. They advance our understanding of the current empirical findings and credibility of this research by using meta-statistical analysis to evaluate research quality, publication selection bias, statistical power, and heterogeneity. The authors conclude that compared to other areas of economics, research on union effects has lower bias but larger problems of statistical power. They argue that Freeman and Medoff's monopoly–collective voice model helped produce more credible results, and they suggest ways to reduce the power and heterogeneity problems in existing research."

"In this article, we re‐examine the relationship between group‐based profit sharing and productivity. Our meta‐regression analysis of 355 estimates from 56 studies controls for publication selection and misspecification biases and investigates the impact of firm‐level unionisation. Profit sharing is positively related to productivity on average, with a stronger relationship where there is higher unionisation. The positive effect of profit sharing on productivity is larger in cooperative firms and in transition economies. Separate meta‐analysis of interactions suggests that profit sharing works better in combination with capital investment and employee participation in decisions."
