Consider a monopsonist who faces a labor supply curve given by Q g = 271) 16, where Q5 is the quantity of labor supplied and w is the wage, and so has a marginal cost of labor given by M C = 8 + Q Their labor demand, reecting the marginal revenue of labor to the monopsonist, is given by Q D = 40 211). a) Sketch a diagram with labor demand, labor supply, and marginal cost, on the usual axes (quantity on the horizontal axis, wage/ costs on the vertical axis). Find and indicate on your diagram the monopsonist's optimal choice of quantity and wage, and the socially efcient quantity and wage. b) Calculate consumer surplus, producer surplus, and (if applicable) deadweight loss at both points you found in a)
