50. A former Governor of the Bank of Canada argued that interest rates must be increased in order to reduce inflation,

for borrowed funds, thus decreasing interest rates in the long run

constant, drives the "price" of borrowing down

PART B: SAQ
(This section contains short answer question and is worth 50 marks)
Question 01 (8 marks)
In your own words, define GDP, the unemployment rate, inflation and deflation.
Gross Domestic Product (GDP) is roughly the market value of all products/services produced in
country in one year. Two types of GDP: Nominal GDP and Real GDP
Unemployment rate is the percentage of people who are unemployed and actively looking for jobs.

Question 04 (5 marks)
In the first quarter of 2009, real GDP (measured in 2002 dollars) was $1492 billion and potential GDP was
$1331 billion. What kind of gap existed and what was its size
GPD gap is the difference between the actual GDP and the potential GDP at any time period. When
the gap is positive, it’s called inflationary/expansionary gap. If the gap is negative it’s called
recessionary/deflationary gap.

The output gap is positive, so in the first quarter of 2009 the economy had an expansionary gap
Question 05 (5 marks)
Describe the sequence of a typical business cycle, beginning with an expansion and ending with an
expansion. Also show them graphically
A. A business cycle begins with an expansion (when real GDP increases) which eventually reaches a
peak (highest point) followed by a contraction (when real GDP decreases). The lowest point of real
GDP, before expansion begins again, is called the trough of the business cycle. A contraction that
lasts for two or more successive quarters is called a recession.
Question 06
If real GDP per person was $50 000 last year and increases to $52 000 this year, what is the annual
economic growth rate?
B. The growth rate = (real GDP per person this year — real GDP per person last year) ÷ real GDP per
person last year × 100 = ($52 000 — $50 000) ÷ $50 000 × 100 = 4 percent.

Spring 2013
Question 07
Deflation lowers the cost of living. Why, then, do economists consider it worse than low inflation
for the economy in general and for you in particular?
A. Falling prices (deflation) can lead consumers to postpone spending, causing economic
contraction and increasing unemployment. Deflation also hurts borrowers — consumers and
businesses — because both consumers’ incomes and business revenues are falling. Consumers
and businesses have less ability to pay back loans, whose dollar amounts do not change. For
these reasons, deflation is worse than low inflation. If you, as a consumer, have loans, you will
have a harder time paying them back. You also are likely to put off spending, hoping that prices
will continue to fall
Question 08
Describe the difference between demand-pull inflation and cost-push inflation.
A. With demand-pull inflation, rising average prices are caused by increases in demand. During
expansions, demand is the key force causing shortages and pulling up prices for inputs (like
wages) and for outputs. With cost-push inflation, rising average prices are caused by decreases in
supply. A decrease in supply caused by increasing costs is the key force pushing up output prices.
Question 09
Explain the difference between a change in aggregate quantity demanded and a change in
aggregate demand. Identify five positive demand shocks that increase aggregate demand.
A. A change in aggregate quantity demanded — the quantity of real GDP macroeconomic players
plan to demand — is caused by a change in the average price level. A change in aggregate
demand, planned spending as the sum of C + I + G + X — IM, is caused by demand shocks. Five
positive demand shocks are more optimistic expectations, falling interest rates, increased
government spending on products/services, increasing GDP in the rest of the world, and a falling
value of the Canadian dollar.
Question 10
If consumers choose to start saving more, explain how the market for loanable funds can rescue
Say’s Law.
A. If consumers start saving more, Say’s Law seems to be threatened since all income earned in
input markets is not spent demanding products/services in output markets. But if banks loan out
savings to businesses who use it for investment spending, that offsets consumer savings,
restoring equality between aggregate income (supply) and aggregate spending (demand).
(Show graphically)
Question 11
Describe the role of animal spirits in the “No” camp explanation of volatile expectations for
investors.
A. The “No” camp believes expectations for investors are volatile because there is fundamental
uncertainty about the future and because investment decisions are easily postponed. This
uncertainty leads investors to rely on the quickly changeable “herd mentality” of other investors.
Investment decisions are based on animal spirits — a gut-level instinct to act.

Question 12
Define the two official measures of the money supply in Canada
A. M1 consists of currency in circulation (government issued paper bills and coins) and demand
deposits. M2 — a broader measure of the money supply — consists of all of M1 plus other
deposits like savings accounts and guaranteed investment certificates (GICs).
Question 13
List two ways that the interest rate is the price of money
A. The interest rate is the price, or opportunity cost, of holding money — what you give up by not
holding your wealth as bonds which pay interest. The interest rate is also the price you pay to
borrow money. If the interest rate is 5 percent, to borrow $100 for a year you have to pay $105
back at the end of the year; the original $100 plus $5 in interest.
Question 14
Explain how interest rates and bond prices are related using an example. What characteristic of
bonds causes this relation?
A. Interest rates and bond prices are inversely related; when one goes down, the other goes up.
Suppose the original value of a bond is $1000 and the bond promises to pay $40 each year. The
interest rate on the bond is $40 ÷ $1000 = 0.04 = 4 percent. If the market price of the bond on the
bond market falls to $800, then the interest rate on the bond is $40 ÷ $800 = 0.05 = 5 percent. A
fall in the price of the bond causes a rise in the interest rate. The characteristic of bonds that
causes this inverse relation is the fixed dollar amount that bonds promise to pay in addition to the
original value. Bonds do not promise a fixed interest rate, they promise a fixed dollar amount
paid regularly.
Question 15
If you have bought a bond as an investment, which way do you hope interest rates will move?
Explain how you will profit from your investment if interest rates move in the direction you hope
A. Once you have bought a bond, the regular interest payments are fixed. The only way you can
make or lose additional money is if the market price of the bond changes. You hope interest rates
will fall, causing the market price of your bond to rise. You can then sell the bond for more
money than you paid for it.
