This paper applies principles from evolutionary biology to the study of unions. We show that unions which maximize the present discounted wages of current members will be displaced in evolutionary competition by unions with more moderate wage policies that allow their firms to live longer. This...

This study examines the impact of unions on wages and employment using data from Uruguay in a period where unions were banned (1973-1984), then legalized with tripartite bargaining (1984-1991) followed by industry-wide or firm-specific bargaining (1992-1997). The relationship between wages and...

In this paper we compare the changing pattern of unionization in OECD countries, review existing evidence, and present new information on cross-country differences in union-nonunion differentials in labor market outcomes, largely from the micro data files of the International Social Survey...

Why do people join open-shop unions when they would receive union wage rates even if they were not members? Why are unionization rates so low in the south-east of England? To address these questions, which we treat as interrelated, the paper considers the idea that unions offer insurance against...

Although there exists a large literature on the effects of trade unions upon wages, there is no published work that uses microeconomic data to examine the employment consequences of unionization. The paper addresses this issue with a new British data set and shows that, even after the addition...

This paper examines the interaction between union wages and the international pattern of production and trade. If union goods are heterogeneous in labor intensity, the introduction of an active union in the domestic country causes only the least labor-intensive range of union goods to be...

This paper analyzes the relation of pension coverage and key plan characteristics to measures of union membership and strength, and to related interactions. The large and significant relationships which are found cannot be explained by, and are often inconsistent with, predictions obtained by...
