A former Governor of the Bank of Canada argued that interest rates must be increased in order to reduce inflation, and this would ultimately result in lower interest rates.

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. ๐๐๐๐๐๐๐๐ฆ๐๐๐๐ก ๐๐๐ก๐ = ๐ข๐๐๐๐๐๐๐ฆ๐๐ ๐๐๐๐๐ข๐ ๐๐๐๐๐ × 100% Inflation rate is the percentage change or the growth rate in the price level.

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. ๐ฎ๐ซ๐ท ๐ฎ๐๐๐ = ๐จ๐๐๐๐๐ ๐น๐๐๐ ๐ฎ๐ซ๐ท๐ − ๐ท๐๐๐๐๐๐๐๐ ๐ฎ๐ซ๐ท๐ ๐บ๐ท๐ ๐บ๐๐2009๐1 = $1492๐๐๐๐๐๐๐ − $1331๐๐๐๐๐๐๐ = $๐๐๐๐๐๐๐๐๐๐ 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. ECON100; Sample Final Exam 13 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. ECON100; Sample Final Exam 14 Spring 2013 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.
