Monopoly,efficient contract,and median voter models of union wage determination: A critical comparison

This article critically compares the monopoly, efficient contract, and median voter models of union wage determination. The models are first analyzed with respect to five theoretical issues: the aggregation of preferences, the principal-agent problem, strike costs, dynamics, and incentive compatibility. The models are then compared with regard to their ability to explain two features of union wage/employment determination: the asymmetric response of union wages to demand shocks and the wide variation in the presence of featherbedding restrictions in union contracts. While all three models suffer from significant short-comings, the median voter model is generally superior.
