In the 1970s and 1980s the labor force participation rate for women increased substantially in the United States. What do you expect that to do to the real wage for men (assume all else equal)?

a. The real wage for men should increase because women make less than men on average. b. The real wage for men should decrease because employers shift their demand to the market for male labor. c. The real wage for men (and for the market overall) should decrease because the labor supply curve shifts to the right. d. The real wage for men (and for the market overall) should increase because the labor supply curve shifts to the left.
