Study Notes

Inflation

Inflation is defined as the general rise in the price level.
Inflation reduces the purchasing power of money.
The consumer price index (CPI) is used to measure the price of a typical market basket of goods and services purchased by consumers.
The CPI is calculated by dividing the price of the market basket in the most recent year by the price of the market basket in a base year and multiplying the result by 100.

Rule of 70

The Rule of 70 is a shortcut to calculate the number of years it takes for the price level to double.
To use the Rule of 70, divide 70 by the percentage rate of inflation.

Demand-Pull Inflation

Demand-pull inflation occurs when spending increases faster than production.
This could happen when the central bank issues too much money.
Prices rise due to excess spending relative to output.

Cost-Push Inflation

Cost-push inflation occurs when there is a rise in per-unit production costs.
This increase in costs forces businesses to raise prices to maintain profitability.

Economic Shocks

Economic shocks are unexpected events that individuals and firms may have trouble adjusting to.
When total spending unexpectedly decreases, firms may not be able to lower prices due to price inflexibility.
This can lead to a decrease in sales and production, ultimately causing GDP to fall.

Causes of Economic Shocks

Economic shocks can be caused by:
- Political events like wars
- Financial instability, such as the recession of 2007
- Irregular innovations, such as the development of the computer and the internet
- Productivity changes, such as unexpected changes in resource availability
- Monetary factors, such as the central bank printing too much money.

Cyclical Impact

Durable goods are affected most by the business cycle:
- Capital goods (such as machines and factories)
- Consumer durables (such as cars, houses and jewelry)
Nondurable consumer goods are affected less:
- Services (such as banking and healthcare)

Calculating Inflation Rates

Find the difference between the CPI in two different years:
Divide this difference by CPI in the earlier year
Multiply by 100 to get the percentage change in prices.
