Card, Lemieux and Riddell argue in their 2002 paper “Unions and Wage Structure” that: They estimate that in 1981, the presence of unions reduced the variance of male wages by 6 percent in the US and 10 per cent in Canada. The corresponding estimates in 1988 are 3 per cent in the US and 13 per cent in Canada. Thus, they estimate that changing unionization patterns contributed to the rise in US wage inequality in the 1980s, but worked in the opposite direction in Canada (20). This conclusion was brought by a combination of model application and literature review, and since unions are a massive force in the US as well as other countries, like Canada and the UK, it is important to determine how this result is possible. Using the theory developed around the topic of unionization, it may be prudent to use such factors as objective function, bargaining range, Rubenstein bargaining, all of which have a large impact on both the level of unionization in a society and effect on wage implications. In addition, the union to non-union factors of the subject have a high impact on the result of the study, indicating that a negative change in unionization participation has contributed to a rise in wage inequality across the private sector, both union and non-union. After a lengthy literature review on the subject, Card and his colleagues argue that “As this discussion [literature review] makes clear, the impact of unions on the structure of relative wages depends on both which types of workers tend to be unionized and on how union relative wage impacts vary across different groups of workers (Card, Lemieux & Riddell, 7).” This means that the demographics of workers in unions and how union wages impact these varying groups is significant, includ... ... middle of paper ... ...ng interest in unions of males over 30 in the United States, however, this equilibrium is fading quickly. Rather, the proportion of union to non-union wages follows more of a reduced form equilibrium model. From the above analysis of Card, Lemieux and Riddell’s work, union theory studied in this course and the work of other noted economists on the subject of unions, it is apparent that not only is the argument Card and his colleagues make plausible, but likely a fact. From the bargaining power of unions and the application of the objective function to explain why the “male over 30” demographic is waning in interest in unions to the application of models to determine if this change could indeed create a rising inequality in wages throughout the sector, it is clear that the potential for such a theory to be successfully applied using models and theories is likely.
