2. (5 marks) By putting out fires firefighters provide a useful service for society, but since they are provided by the government free there is no market price associated with their services. In the expenditure approach to measuring GDP how is the value of firefighting services accounted for?

3. (5 marks) Suppose there are only two consumption goods in the Canadian the economy: apples and oranges. And further suppose that over time the prices of apples and oranges are both increasing, but the price of apples is increasing at a more rapid rate. In these circumstances explain why Statistics Canada will adjust the consumption bundle in the next revision of the Consumer Price Index (CPI).

________________________________________________________________________ DO NOT WRITE BELOW THIS LINE 4. (8 marks) In the market for loanable funds suppose that the demand for funds comes solely from the demand for funds by the government to finance its deficit. That is firms demand no funds for investment at any interest rate.

If the government reduces its spending, and reduces but does not eliminate the government deficit, what impact will this have on the equilibrium interest rate and the level of consumption spending? Briefly explain using a diagram to illustrate your answer.

5. (6 marks) (a) Suppose that Angela deposits \$1,000 of currency (cash) into her account at her local bank. If the required (or desired in Canada) reserve ratio (RRR) is 0.05 for the banking system, what is the maximum amount by which deposits in the entire banking system could increase? Show how you calculated your answer.

(b) If Angelas bank decided to keep her deposit as excessive reserves by how much would deposits in the entire banking system increase? Explain in a sentence.
