Question 4
Suppose that there is a country called NSCC Republic. The Bureau of Labor Statistics of
NSCC Republic announced that in January 2009, of all working age adult populations,
100,000 were unemployed, 700,000 were employed, and 200,000 were not in the labor
force. How big was the labor force? (1 pt.) What was the labor-force participation rate?
(1 pt.) What was the unemployment rate? (1 pt.)Need to show detailed calculations.
Labor force:

Question 5 Draw per-worker production function for following cases. (4 pts.)
1. The per-worker production function shows the relationship btwn capital per
worker (K/L) and real GDP per worker (Y/L), holding technology constant.
Increases in capital per worker increase output per worker, but a diminishing rate.
(2 pts.)
2. The per-worker production function shows the relationship btwn capital per
worker and real GDP per worker with technology change. You should show the
change of production function that allows more output per worker with the same
amount of capital per worker. (2 pts.)

Question 6 (4 Pts., 1 pt. each)
Using supply-and-demand diagrams, show the effect of the following events on the
market for loanable fund market and show changes of interest rate (i*) and equilibrium
quantity of loanable fund (Qf*).
1. A change in the tax law to encourage Americans to save. (Note: Gov’t lowers tax
on capital gains like interest income.)
