Q

Aggregate Demand/Aggregate Supply

A

In unit one, we explored demand and supply in individual markets
Microeconomic level
Macroeconomics uses the Aggregate Demand/Aggregate Supply (AD/AS) model
works on the same principles, but includes all the goods and services produced within a nation within a given time period

Q

1) Demand pull

A

There is an increase in aggregate demand (AD) when there is more full employment
This creates an excess demand
Expectations are important for this factor
If we expect prices to rise, we buy now, increasing demand, causing prices to rise

Q

2) Cost push

A

Anything that makes the supply curve shift left, indicating a decrease in supply
Increase in factors of production for business firms
- Tax increases (ie. sales tax)
- Wage increases
- Increase in energy costs
Makes it more expensive to produce goods

Q

3) Imported cost push

A

If the price of important imports increase, then the price of goods increase as a result
Example: If the price of OPEC oil increases, it will cause inflation for countries that import oil

Q

4) Structural

A

Occurs because of institutional arrangement in economy
Competition for products or labour does not exist (e.g. doctors, civil servants)
Assumes resources do not move quickly between institutions
- Easy for prices and wages to increase, but not easy for them to decrease

Shortages in expanding industries
On average, demand increases over time; therefore prices increase over time

Q

How is inflation measured?

A

Consumer Price Index (CPI): A price index that measures changes in the prices of consumer goods
In Canada, the Consumer Price Index is used to measure inflation
It is based on the cost of a basket of goods and services consumed by the “typical Canadian family”
typical Canadian family = Any size family, any income level, both urban and rural areas
Excludes those in communal colonies, prison inmates, and chronic care patients in hospitals & nursing homes

Q

Baskets of goods/services

A

Items that Canadians purchase are put into one of eight categories:
- Food
- Shelter
- Household Operations
- Clothing/Footwear
- Transportation
- Health/Personal Care
- Recreation/Education
- Alcohol/Tobacco
These items are then weighted to reflect their importance in a typical household
The pie chart to the right shows Canada’s CPI weights for 1992

Q

Calculation CPI

A

CPI can be used to compare changes in price of particular items or overall inflation from one year to another

Formula: P(inflation)= CPI(year 2) - CPI(year 1) / CPI (year 1) x100

Q

CPI Limitations

A
  • Sample of population, not individuals
    Example: Could be a 10% increase due to higher tobacco prices, but you might not smoke
  • Changing composition of ‘basket’ over time
    Stats Canada only surveys once every ten years, and revises weights
    Example: Cell phones are omnipresent now, but only used by certain professions 20 years ago
  • Quality changes not included
    Example: a computer being sold today is very different in quality and price than a computer sold when the base year basket was created
    A great deal of what’s in the average Canadian household’s annual shopping cart is NOT in CPI “basket”
    Does not consider substitutes
    Example: generic rather than brand names

Q

Inflation consequences

A

Inflation redistributes income
Some benefit
- Borrowers - Since money is worth less, it becomes easier to pay back loans from previous years
Some lose
- Lenders - The money they get back from loans is worth less than it was when they lent it
- Unskilled workers - Since they get paid less, the increase represents a greater percentage of their wage
- Non-union workers - don’t negotiate pay as often as union workers (every 2-3 years)
Unions use indexing to adjust wages in negotiations
- Fixed income earners (pensioners) - Income stays the same as cost of living increases
