Chapter 4: What Macroeconomics is all about Flashcards
(57 cards)
Key Macroeconomic Variables
national income, unemployment, productivity, inflation, interest rates, exchange rates, and net exports
income
production of output
Aggregation problem
a summary measure, such as GDP
Nominal National Income
- a method of aggregation which is measured in current dollars (CAD)
- multiply the number of units of each good produced, by the price at which each unit is sold (every bar of steel, every loaf of bread). then sum these values across all the different goods and services produced in the economy to give the quantity of total output measued in CAD
- also refered to as current dollar national income or constant-dollar national income
- Total national income measured in current dollars. Also called current-dollar national income
Real National Income
- a method of aggregation which is measured in constant (base-period) dollars, reflecting quantity changes
- measures to what extent any change in national income is due to higher/lower quantities or to higher/lower prices
- national income measured in constant (base-period) dollars. it changes only when quantities change.
helps with inflation measurement. includes a base year.
Real GDP
Measures the quantity of total output produced by the nation’s economy annually
Long-Run Trend
economic growth
USA economy vs. Canadian economy
Short-Run Fluctuations
Business cycle
lack of workers, to high unemployment
Potential Output
- what the economy could produce if all
resources were employed at their normal levels of utilization - The real GDP that the economy would produce if its productive resources were fully employed. Also called potential GDP.
- notated by (Y*)
also referred to as the Full Employment Output or Potential GDP
Output Gap
- Difference between potential output and actual output
- computed by Y - Y*
- when actual output is less than potential (Y<Y*) then not all resources are being utilized, this is a recessionary gap
- When actual output exceeds potential output (Y>Y*) the economy is operating in excess and will not be able to sustain that level of production. this is an inflationary gap
Recessionary gap
- Y < Y∗
- happens when an economy is not operating at full potential
- this may be due to higher unemployment
Inflationary gap
- *Y > Y∗
- this happens when an economy is operating in excess, and goes over their potential output
- this economy will not be able to operate sustainably
- often times this happens to workers picking up extra shifts, etc.
why do economists look at long run trends?
The long-run trend in real per capita national income is an important determinant of improvements in a society s overall standard of living (economic growth makes people materially better off on average).
why do economists look at short run trends?
This allows economists to make predictions. if there is recessionary gap, there is higher unemployment and suffering, lost output and economic waste. when there is an inflationary gap, there is risk of high inflation, causing goods to be expensive and money to be worth less.
Employment
- number of people 15 years or older holding jobs
Unemployment
- Number of people 15 years or older not employed but actively seeking work
labour force
employed + unemployed. does not include students or people actively looking for a job (stay at home wives)
Unemployment Rate
- Percentage of unemployed in the
labour force - equal to the number of people unemployed/number of people in the labour force x 100
NAIRU
non-accelerating inflation rate of unemployment. Above = recession, Below = inflation. unemployment rate when Y = Y∗
what is natural for an economy
Why was there a spike in the labour force and production starting around the mid-1970s?
Women entering the work force, immigration, allowed for growth in employment and the labour force
Frictional unemployment
more short term. natural turnover, people get fired, rehired, moved departments, etc. normal for an economy.
Structural unemployment
- longer term. stems from too many jobs and too little workers with the experience needed, or too little jobs and too many workers
Why does unemployment matter?
Loss of income, Loss of output, Associated with crime, mental illness, and social unrest.
Productivity
- A measure of output per unit of input. Often measured as GDP per worker or GDP per hour worked.
- The level of real GDP divided by the level of employment (or total hours worked)
- has increased in almost every year over the past half-century in Canada
- measuring per hour work is a more accurate measurement as the average number of hours worked per employed worker changes over time, takes into account the changes in hours worked
- single largest cause of rising living standards over long periods of time
can be determinate in long-term living standards
