commission. Which compensation scheme would require more monitoring by
supervisors? In which case do flrms have an incentive to pay efficiency wages?
(b) (4 points) "The latest employment data suggest that number of employed increased by
30,000, and number of unemployed decreased by 40,000.'(#xplain why the increase in
employment does not match the decrease in unemployment~at happened to the labour
force? Did the unemployment rate increase or decrease?

(a) '(5 points) The Bank of Canada conducts a $5 million open market purchase of
government bonds.3ll!at will happen to money supply? If people hold all money as
currency, what is the change in money supply? If people hold all money as deposits and
banks maintain a reserve ratio of 25%, what is the change in money supply?
(b) (3 points) Assume that the quantity theory of money and the Fisher effect both hold.
What happens to inflation, real interest rate, and nominal interest rate when the money
supply growth rate decreases from 8 percent to 5 percent?

(a) (4 points) Henry Ford, the founder of the Ford Motor Cq~pany, paid his worker $5 a day
(dollars in early 1900s) which was about twice the going'tige at that time. Explain why
Henry Ford called the $5-a-day wage "one of the finest cost cutting moves".
(b) (4 points) If prices change in a way that leaves the overall price level unchanged, then
no one is better or worse off ". Explain why this statement is wrong.
