The Focus of Macroeconomics
Macroeconomics focuses on the behavior of key macroeconomic
variables including:
o
???
Since the early 1990s, the inflation rate has been in the narrow
range of 1-3% per year
- consistent with the Bank of Canada target.
3. The unemployment rate the proportion of the labour force out of
work (Fig 1-3)
Canadian Historical Data on the UR
The UR is strangely countercyclical with GDP
o Rising in recessions and falling in expansions
Unemployment was highest in the 1930s
[during the Great Depression] and lowest in the 1940s [during
WWI]
Since 1945, there has been a gradual upward trend in
unemployment, but endence in recent years suggest this trend may
be easing.
4. The interest rate the cost of borrowing and return to saving
5. The (nominal) exchange rate the cost of one currency in terms of
another
Behavior of prices: tlekible (LR) & sticky (SR) D S (many not).
Market clearing (equilibrium)

Some Rule for Calculating GDP

Only pages 1-3 are available for preview. Some parts have been intentionally blurred.

1. The importance of inventories. Since we want to measure production
in a given year, we add the value of unsold goods to inventories, and
include this value in the GDP calculation.
2. We add-up the many and varied goods and services by multiplying the
quantity by the market price.
3. Exclude intermediate goods. Count the value of final goods & services
only in the GDP calculation, otherwise, double-counting will occur.
4. If goods or services don’t have a price, use an imputed value
Ex. (1) imputed rent on owner-occupied housing
(2) government services are valued at cost
5. Excluded:
Used goods (b/c been included)
Home production
Underground economy (transaction that don’t go through market)
Services of durable goods
(S 7)
Investment (I) (net financial investment)
i.e. Domino Pizza buying a store
Notes: Investment the purchase of newly produced goods/services to add
to the capital stock.
By convention, the purchase of new housing stock
The value of inventories
(S 16)
Government (All government levels)
Defn: Transfer Payments
Direct transfers of money from the government to individuals not in
exchange for production. (no production involved)
Net exports: NX = EX IM

Real vs Nominal GDP
Nominal GDP output valued at current year prices

Nominal GDP measures the value of goods & services produced in

Real GDP output valued at constant (base year) prices

GDP Deflator (price index)
Defn: The GDP deflator measures the price of output relative to its level
in the base year.
The GDP deflator is a price index which measures the overall price level.
Calculation:
GDP _Deflator =Nominal _GDP
Real _GDP ´100

In this definition of the GDP Deflator, all the quantity terms will be the
same, reflecting only the relative change in prices.
