Monopsony in the Labor Market,Minimum Wages and the Time Horizon: Some Unresolved Issues

This article discusses development of optimal solutions for monopsony in the labour market for the long run (when labour and capital are both flexible). It is shown that binding minimum wages up to a certain degree pushes the monopsonists to choose a high capital intensity of production, just as high as or even higher than that chosen when there is no regulation for minimum wages. Thereby, we demonstrate the existence of re-switching effects in the tradition of Piero Sraffa. The second part of the paper recalculates and analyzes earlier results by making use of the rather general constant elasticity of substitution production function. Based on a numerical solution for optimal monopsony under different regimes (no minimum wage, minimum wages of different values, etc.), we formulate a two-period game between the government and the monopsonistic firm (‘minimum wage game’). Finally, we analyze the relationship between the elasticity of substitution on the one hand and likely levels of employment on the other hand, after introduction of minimum wages.
