Q

inflationary gap is when…

A

means high demand for workers, competition in labour market, higher wages and prices

25
in the short run, when Y > Y*...
there's an INFLATIONARY GAP risk of HIGH INFLATION RATES
26
employment
number of workers (15+) holding jobs
27
unemplyment
number not employed but actively seeking work
28
labour force
employed + unemployed
29
unemployment rate
percentage of unemployed in the labour force
30
unemployment rate equation
number of people unemployed / number of people in the labour force x 100
31
even when Y = Y*, some __________ exists
unemployment 1. frictional unemployment (natural turnover) 2. structural unemployment (mismatch between jobs and workers)
32
there's cyclical unemployment when...
Y < Y*
33
when Y = Y*, the unemployment rate is called...
the natural rate of unemployment NAIRU
34
current natural rate of unemployment
below 7%
35
since 1976, what has happened to the labour force and employment rates?
they've grown with only a few interruptions
36
employment has grown roughly in line with the growth in...
the labour force the data also show that short-term fluctuations in unemployment rate have been substantial
37
unemployment rate in 2019 versus 1982 versus Covid
2019: 5.7% 1982: 12% Covid: 13.7%
38
social significance: unemployment
1. loss of income 2. loss of output 3. associated with crime, mental illness, social unrest
39
productivity definition
measure of output per unit of input often measured as GDP per worker or GDP per hour worked
40
2 measures of productivity
1. GDP per worker 2. GDP per hour worked
41
largest determinant of long-run material living standards
increases in productivity
42
price level
average level of all prices in the economy
43
inflation
rate at which the price level is CHANGING if inflation is POSITIVE, price level is increasing (costs more and more to buy the same basket of goods)
44
CPI
consumer price index based on the price of a typical "consumption basket" relative to a base year
45
CPI equation
don't forget to memorize CPI = (cost of basket in current year / cost of basket in base year) x 100
46
why does inflation matter?
1. we value money not for itself, but for what we can purchase with it 2. purchasing power 3. effects of inflation: reduces purchasing power, reduces the real value of sums fixed in nominal terms
47
purchasing power
amount of goods/services a unit of money can buy
48
if households & firms fully anticipate inflation over the coming year...
they will be able to ADJUST many NOMINAL PRICES and WAGES to maintain their real values
49
unanticipated inflation generally leads to...
more CHANGES in the real value of prices and wages
50
in reality, inflation is rarely fully...
anticipated or unanticipated as a result, some adjustments in wages and prices are made but not all the adjustments that would be required to leave the economy's allocation of resources unaffected
51
price level and inflation rate, 1960-2020
trend in PRICE LEVEL has been upward over the past half-century rate of INFLATION has varied from almost 0 to more than 12% since 1960 shot up during COVID, but now being brought down
52
interest rate
the price of credit the flow of credit = crucial to firms and households in a modern economy
53
2 types of interest rates
1. nominal interest rate 2. real interest rate
54
nominal interest rate
rate expressed in MONEY TERMS
55
real interest rate
rate expressed in terms of PURCHASING POWER
56
what interest rate does the burden of borrowing depend on?
the real interest rate
57
understanding nominal and real interest rates: friend lends you $100 today, and a year later you pay her $108
$100: repayment of the loan (principal) $8: payment of the interest NOMINAL INTEREST RATE: 8% per year 1. if the price level remains constant: friend can buy 8% more ^ real rate of interest is 8% 2. if the price level increases by 8%: friend can buy the same as before ^ real rate of interest is 0%
58
prime interest rate
interest rate that banks charge to their best business customers
59
bank rate interest rate
interest rate that the Bank of Canada charges on short-term loans to commercial banks
60
we speak of interest rates as a whole, even though there are many types, because...
they all fluctuate together if one type goes up, the others do too
61
by manipulating the bank interest rate...
the central bank changes the rate that commercial banks pay them when they borrow this automatically changes all the other interests rates (ie. people's car, house etc rates)
62
what do govs do to interest rates when inflation is high?
they increase the interest rates leads to less spending, less consumption, less need to produce, higher unemployment, prices increase less quickly ^ this all slows inflation once inflation nears 2%, start to reduce interest rates
63
exchange rate
the number of Canadian dollars required to purchase one unit of foreign currency
64
depreciation of the Canadian dollar
means that it's worth less on the foreign exchange market rise in the exchange rate
65
what 2 groups of things have important effects on the Cad exchange rate?
1. domestic policy 2. external events
66
what determines the exchange rate?
it isn't fixed demand/the market determines it ie. foreign govs/people want to buy Cad goods, if our exports are higher then increase in demand for Cad dollars the more we export, the stronger demand to Cad dollars
67
who aren't happy when Cad dollar is strong?
exporters harder to sell their goods in international market when Cad dollar is strong
68
4 factors affecting the CAD exchange rate
1. MONETARY POLICY: higher interest rates attract foreign capital (appreciation) 2. FISCAL POLICY: deficits may weaken the dollar, economic growth can strengthen it 3. INFLATION: high inflation reduces demand for CAD (depreciation) 4. TRADE BALANCE: surpluses strengthen CAD, deficits weaken it
69
Cad-US exchange rate over past 5 decades
has been quite volatile
70
net exports
the difference between exports and imports net exports stay pretty steady, only mildly fluctuate fell in 2020 (because both imports and exports decreased)
71
3 points on long-term economic growth
1. long-term trends of rising total output and output per person have led to higher living standards 2. long-term growth is crucial for improving living standards across generations 3. debate exists on extent to which government policy can influence economy's long-run growth rate
72
3 points on short-term fluctuations
1. short-term fluctuations lead economists to study business cycles 2. debate exists on effectiveness of monetary and fiscal policy in influencing these fluctuations 3. some economists argue that, despite policy power, governments should avoid frequent "fine-tuning" of the economy through spending and taxing changes
