Good Faith Effort 28 -- Market Power in Factor Markets

  1. We write the percentage markdown of wages below marginal revenue product as (MRP - W)/W. For a profit-maximizing wage setter, how does the size of this markdown depend on price elasticity of supply? Why can this markdown be viewed as a measure of monopsony power?

  2. Use Excel to help you answer this question (or do the math if you are able). A wage-setting firm faces the following market supply curve:
          Ws(L) = 5+0.0025*L,
    where L is units of labor per time period and W is wages, measured in dollars per unit of labor. The firm's marginal product function is given by MP(L) = 5-0.001*L. Finally, the firm sells it output is a perfectly competitive product market at a price P* = $5 per unit. Assume that the firm seeks to maximize profit.

    What is the firm's level of hiring and what wage rate will it pay? Show your work.
