Q

Define the output gap and what it measures

A

Output gap = Y - Y* - it measures the difference between potential output (can at best be estimated) and actual output.

Q

How does the recessionary and inflationary gaps are translated in terms of PPB?

A

Recessionary: inside the PPB (lack of production)
Inflationary: outside the PPB (excess production)
= 0: on the PPB

25
Which is the type of unemployment that points to a recession?
Cyclical unemployment
26
Which two types of unemployment exist even when Canada is at full employment?
Structural and frictional unemployment
27
Define Structural unemployment
Mismatch between jobs and workers
28
Define Frictional unemployment
Natural turnover in the labour market
29
Define Cyclical unemployment
When Y
30
Until what % of inflation can we tolerate booms?
3%
31
Does everyone benefit from economic growth?
No
32
What are 5 measures that affect GDP?
1. Employment, unemployment, and labour force 2. Productivity 3. Inflation and price level 4. Interest rates 5. Exchange rates and trade flows
33
Define Employment
Total number of people who have a job
34
Define Unemployment
Total number of people who don't have a job but are actively looking
35
Define Labour Force
Total number of people employed or unemployed (usually 15-65 y.o.)
36
What is the formula for unemployment rate?
= (# of ppl unemployed/# of ppl in labour force)*100
37
How can employment rise? (2)
1. If the labour force increase and the fraction of unemployment vs employment stays cst, employment increase 2. If the labour force stays cst, but the fraction increase, employment increase (e.g. 3/5 work now instead of 1/5 before)
38
Define Potential GDP in terms of employment
We calculate potential GDP at FULL employent
39
Define Full employment in Canada
Level where everybody who wants to find a job at current wages will do.
40
Name 2 ways of increasing outputs
1. more employment (improve in employment) | 2. more output/person (improve in productivity)
41
Why would people don't want to work in the current labour market? (2)
1. Natural turnover, time in between two jobs (frictional unemployment) 2. Mismatch between available profile and jobs requirements (structural unemployment) These two are already taken into consideration in GDP (up to 3%). We stay at full employment even when they are present
42
Why do we worry so much about unemployment?
If an Economy has long-term unemployment, has a bigger burden on it = less income, loss of output. Associated with higher crime, mental illness, and general social unrest.
43
Define productivity
Measure of the amount of output that the economy produces per unit of input
44
What does an increase in Y* indicate in the L-R?
Economic growth S-R: Y L-R: Y* Want to have Y reach Y* - close the gap. BUT Y* can at best be estimated
45
What is the formula for Labour Productivity
Level of real GDP/number of workers (or total hours worked)
46
What is the single largest cause of rising material living standards over long period of time?
Productivity growth
47
Name 3 ways to increase productivity.
1. Increase in ppl employed 2. increase in capital employed 3. increase in productivity
48
What happens when there is a constant rise in price (L-R inflation)?
Demand curve shifts right
49
Define Price level
The average of all prices in the economy expressed as an index number
50
Define CPI (Consumer Price Index)
Average price of basket of commodities consumed by the average consumer
51
What is the formula to calculate the Rate of Inflation?
Use CPI data | [(Year 2 - Year 1)/Year 1]*100
52
How do you calculate an Index number?
(Cost of market basket in a given year/Cost of market basket at base)*100
53
Why does inflation matter?
1. Reduce purchasing power | 2. Reduce the real value of any sum fixed in nominal (dollar) terms
54
What are the 2 categories of inflation
fully anticipated and unanticipated
55
What happens if inflation is underestimated?
Purchasing power and standard of living decrease
56
Define Interest Rate
The price paid per dollar borrowed per period of time, expressed either as a proportion (e.g., 0.06) or a percentage (e.g., 6%)
57
Define Overnight (or discounted) Rate
I.R. of one bank borrowing to another bank to meet daily payment. If overestimated: lend surplus to other at overnight I.R. Fluctuates depending on demand
58
Compare Nominal interest rate and Real interest rate
Nominal: I.R. in % e.g. borrowed a 100$ at 10% I.R. = pay 110$ Real I.R.: real number of commodity I can buy if I can anticipate the I.R. Charge nominal I.R. such that real I.R. stays constant.
59
How to calculate exchange rate in this class
domestic/foreign (e.g., 1 USD buys 1.3 CAD)
60
How does the exchange rate ratio change with appreciation and depreciation?
Appreciation of domestic currency: fall in the ratio (e.g., 1 USD buys (less) CAD) = Imports increase, export decrease Depreciation of domestic currency: raise in the ratio (e.g., 1 USD buy (more) CAD) = Imports decrease, exports increase
61
Define Net exports
Exports - Imports = trade balance
62
What is a reason for Canada's increase in export and import over the past 45 years?
Trade agreement (NAFTA) - takes out tariffs, so total volume of exchange increases)
63
Which of the following indicates an increase in labour productivity?
a) Inc in real GDP and pop b) inc in real GDP and labour forme c) a more rapide inc. in R-GDP than in pop d) a more rapide inc. in R-GDP than in labour force e) a more rapide inc. in R-GDP than in level of employment
64
What does the real interest rate measure?
The burden of borrowing and also the real return on an asset in terms of its purchasing power
65
Define deficit
when imports is higher than exports
66
What are two reasons that might help to explain Canada's negative trade balance from 2009 to 2012?
1. Appreciation of CAD (imp inc and exp dec.) | 2. A decrease in income in Canada's main trading partners
67
What is another way of putting L-R vs S-R fluctuations
L-R in linked to economic growth | S-R is linked to fluctuation in the business cycle (peak and trough/ recession and recovery
68
An upward trend in real national income is also called
economic growth
69
How do you calculate real and nominal interest rate?
Real interest rate = Nominal interest rate - inflation rate
70
A price Index changes from 120 to 114 over a particular period of time. The % change in the price level was?
-5% (114/120=0.95) - indicates a fall of 0.05 in the price level
