Contrary to conventional wisdom, higher minimum wages may lead to greater levels of employment under perfect competition. We demonstrate this possibility in a simple general-equilibrium model of involuntary unemployment, with two goods produced by two factors and consumed by two representative households. Within our model, hiking a minimum wage redistributes income between heterogeneous consumers. This redistribution may create an excess demand for the labor-intensive good, and hence increase total employment to restore equilibrium, despite the fact that every firm becomes less labor intensive.
| IN TRO DUCT IO NAs we show within a simple general-equilibrium model of perfect competition, higher minimum wages may paradoxically lead to greater levels of total employment. Such a paradox has typically been associated with departures from perfectly competitive behavior. For example, the pioneering article by Stigler (1946) includes a monopsonist in the labor market, Manning (1995) has firms setting wages to affect effort, and Flinn (2006) considers wage bargaining with search-and-matching frictions. In contrast to these studies, the present paper assumes that firms take wages as given, in the way usually associated with perfect competition.Intuitively, a hike in the minimum wage has three effects. First, producers engage in factor substitution, leading to a reduction in labor intensity within each industry. Second, because the wage hike raises the relative price of the labor-intensive good, consumers substitute away from this good, toward the capital-intensive one. Third, income is redistributed between heterogeneous households with different marginal propensities to consume, possibly increasing the relative demand for the labor-intensive good. If this income-redistribution effect outweighs the combined substitution effects in production and consumption, the resulting excess demand for the labor-intensive good requires an increase in employment to restore equilibrium.
