1) Suppose the actual unemployment rate increases. This will cause: A) an upward shift in the WS curve. B) a downward shift in the WS curve. C) an upward shift in the PS curve. D) a movement along the WS and the PS curves.
D Changes in actual unemployment rate or wage rate, cause a movement along the WS and the PS curves, not a shift. So what causes movements? As we have F(un, z) =1 / 1 + m, we may see that the positions of the wage-setting and price-setting curves, and thus the equilibrium unemployment rate, depend on both z and m. Consider two examples: (1) An increase in unemployment benefits. An increase in unemployment benefits can be represented by an increase in z: Since an increase in benefits makes the prospect of unemployment less painful, it increases the wage set by wage setters at a given unemployment rate. So it shifts the wage-setting relation up. The economy moves along the PS line. The natural rate of unemployment increases. In words: At a given unemployment rate, higher unemployment benefits lead to a higher real wage. A higher unemployment rate is needed to bring the real wage back to what firms are willing to pay. (2) A less stringent enforcement of existing antitrust legislation. To the extent that this allows firms to collude more easily and increase their market power, it will lead to an increase in their markup—an increase in m. The increase in m implies a decrease in the real wage paid by firms, and so it shifts the price-setting relation down. The economy moves along WS. The equilibrium moves and the natural rate of unemployment increases. In words: By letting firms increase their prices given the wage, less stringent enforcement of antitrust legislation leads to a decrease in the real wage. Higher unemployment is required to make workers accept this lower real wage, leading to an increase in the natural rate of unemployment.
