Union-nonunion wage differentials and the functional distribution of income: Some simulation results from a general equilibrium model

During the past two decades, a number of studies have established the ability of unions to obtain wages for their members that exceed the payment to similar but nonunionized workers. This article investigates empirically the impact that this wage differential has on the real incomes of union labor, nonunion labor, and capital. The analysis is accomplished by solving explicitly a numerically specified general equilibrium system with and without the union wage premium. Comparison of real factor incomes in each equilibrium yields the desired information. The findings indicate that union labor gains as a result of the differential, while nonunion labor and capital lose. This outcome is realized both in terms of real income levels and in a redistributive sense.
