A. Only 1

B. Only 2 and 3

C. Only 1 and 3

D. Only 2

E. Only 3

Feedback:

An increase in the mark-up by ﬁrms will cause a decrease in real wages. See the following example:

Howe ver, workers are not able to determine the real wage through nominal wage bargaining. The wage-setting
relationship does not tell us what the actual real wage will be. Workers can try to achieve a desired or targeted
real wage by bargaining for a nominal wage, but whether the desired or targeted real wage is achieved will
depend on what happens to the price level. And the price level is determined by the mark-up used by ﬁrms.

Therefore, workers are not able to increase their real wages through an increase in their nominal wages.

There is a positive relationship between the mark-up and the price per unit.
