Question 14

A rightward shift in the demand for labor ($$L_d) is $$most likely caused by which of the following?

Accepted Answer

Increase in productivity

Question 15

If the supply of labor increases, what happens to the equilibrium real wage ($$w/p) $$and quantity of labor ($$L) in $$the labor market?

Accepted Answer

Real wage falls; quantity of labor rises.

Question 16

Which of the following would NOT shift the supply of loanable funds curve?

Accepted Answer

Change in expected profits

Question 17

If exports ($$X) $$exceed imports ($$M$$), what is the effect on the supply of loanable funds in the domestic market?
