Consider a monopoly of labor.  The monopolist faces the market labor supply curve.  Suppose if the monopolist invests $A in advertising, the labor supply curve will shift right. (10 points)

• Using a graph, plot the marginal expenditure, labor supply and labor demand curves before and after advertising.  Show the change in equilibrium wage and quantity of labor.
• Determine when the monopolist would choose to advertise [Hint: look at the monopolist case of advertising but think monopolist.]
