Youth-adult differences in the demand for unionization: Are American, British, and Canadian workers all that different?

We examine demand for union membership amongst young and adult workers in Britain, Canada, and the United States. Using a model of representation advanced by Farber (1983, 2001) and Riddell (1993), we find that a majority of the union density differential between young and adult workers in all three countries is due to supply-side constraints rather than a lower desire for unionization by the young. This finding lends credence to two conjectures: first, tastes for collective representation do not differ substantially among workers (either by nationality or by age) and second, union representation can be fruitfully modeled as an experience-good. The experience-good properties of union membership explain the persistence of union density differentials (in this case between youth and adults) in the face of equal levels of desired representation.
