Minimum wages for Ronald McDonald monopsonies : a theory of monopsonistic competition by V Bhaskar and Ted To - a comment

Bhaskar and To (1999) develop a model of monopsonistic competition and solve explicitly for equilibrium. While a minimum wage set just above the unconstrained optimum leads firms to increase employment it also causes firm exit as profits fall. In this note I show that the employment and welfare effects of the minimum wage which Bhaskar and To had thought to be ambiguous when firm exit was accounted for are in fact unambiguously positive.
