Study Notes
Macroeconomics - Chapter 8: The Cost of Living
- GDP provides no information on purchasing power within a country
- Cost of living is based on a comprehensive view of prices and incomes
- A consistent rate of price and income change globally would simplify cost of living calculations
- Measuring price changes over time is complex
- Economists track individual price changes, weighting items by their proportion of a typical consumer's budget
- This process establishes a measure of how overall cost of living has evolved
Measuring Price Changes Over Time
- Some price changes matter more than others to consumers
- Key factors are:
- Magnitude of price change
- Proportion of budget allocated to the item
- Economists track price changes, prioritizing impactful items in consumer's budgets
- This method measures changes to the overall cost of living
The Consumer Price Index (CPI)
- A commonly used index to track changes in cost of living within a typical Canadian household
- Statistics Canada computes and reports the CPI monthly
- Data encompass over 600 different goods and services
Four Steps to Compute CPI and Inflation Rate
-
Determine the market basket:
- List specific goods and services with fixed quantities corresponding to typical household spending (using FAMEX)
- Basket weights are available
-
Compute the cost of the market basket: Determine the current prices of all goods and services in the basket
-
Choose base year: Statistics Canada uses 2002
- Calculate the CPI for the current year
- The formula for calculating the CPI for a current year is:
CPI for current year = (Cost of basket in current year / Cost of basket in base year) * 100
-
Compute the Inflation Rate:
-
Calculate the inflation rate using the formula:
Inflation rate = [(CPI<sub>t</sub> - CPI<sub>t-1</sub>) / CPI<sub>t-1</sub>] * 100% -
where CPIt is the CPI for the current year and CPIt-1 is the CPI from the prior year
-
The Consumer Price Index (continued)
- Variety of CPI calculations available (e.g., headline inflation, core inflation, CPI-common, CPI-median, CPI-trim)
- Headline inflation tracks changes in prices for the entire market basket of the average urban household
- Core inflation measures price changes in the underlying trend of inflation
- Statistics Canada provides multiple measures to capture the nuances in inflation trends
Challenges in Measuring Price Changes
- CPI aims to balance consumer consumption across different life stages and situations
- Represents an average across a large consumer population
- Requires adjustments for changes in prices, trends, innovation, and substitutions within goods and services
- Frequent updates to maintain accuracy by using a consistently updated market basket
- Aims to reflect the cost of maintaining a given standard of living
CPI and COVID-19
- COVID-19 caused significant shifts in spending patterns
- This made the standard CPI less effective as an indicator
- Statistics Canada created an adjusted CPI that considered pandemic spending changes
Using Price Indices
- Comparing dollar figures across different time periods using price indices
- Indexing automatically adjusts payments (e.g., wages) to match the rising cost of living (COLA)
Deflating Nominal Variables
- Incomes should naturally rise with time to account for inflation in macroeconomic theory
- Calculating the current value of past dollar amounts using:
Current Value<sub>year Y</sub> = Past Value<sub>year X</sub> x [(CPI<sub>year Y</sub>) / (CPI<sub>year X</sub>)]
Other Price Indices
- Producer Price Index (PPI): Measures prices of goods and services purchased by firms (includes capital goods and raw materials, often excluded from consumer baskets)
- World Bank's International Comparison Program (ICP) Index: Primary gauge for international price comparisons. This index is used by the World Bank and others.
Other Price Indices (continued)
- Purchasing Power Parity (PPP): Predicts that goods cost the same globally after accounting for exchange rates
- PPP-adjusted GDP adjusts for differences among countries in the cost of goods and services across countries. This allows for a more accurate comparison of economic output.
