Inflation Rate

The inflation rate is the percentage change in the CPI from one period to the next.

How is the CPI calculated?

The CPI is calculated by dividing the price of a basket of goods and services in a given year by the price of the same basket in the base year, and then multiplying by 100.

What is the base year in the CPI?

The base year is the year against which the prices of other years are compared. It is typically updated every few years to reflect changes in consumer spending patterns.

What is the CPI?

The CPI is a measure of the average change over time in the prices paid by urban consumers for a basket of consumer goods and services.

Quality Bias in CPI

The CPI does not account for quality improvements that do not involve price changes, leading to an underestimation of the true cost of living.

Substitution Bias in CPI

The CPI assumes consumers buy the same amount of goods and services in each period, even though they may switch to cheaper alternatives when prices increase.

New Goods in CPI

New goods and services are not included in the CPI basket until they become widely available, which can underestimate the true cost of living.

How do nominal and real interest rates affect savings?

If the nominal interest rate is 3% and the inflation rate is 1%, the dollar value of savings increases by 3% (the nominal interest rate), but the purchasing power of those savings only increases by 2% (the difference between the nominal interest rate and the inflation rate).

Why is the real interest rate important?

The real interest rate is a measure of the increase in purchasing power from saving or lending. It is calculated by subtracting the inflation rate from the nominal interest rate.

Explain how nominal and real interest rates work together.

When the nominal interest rate is 6% and the expected inflation rate is 4%, the dollar value of savings increases by 6% and the real value of those savings increases by 2%. This means you can purchase 2% more goods and services with your saved money after accounting for inflation.

What does it mean when the real interest rate is positive or negative?

A positive real interest rate suggests that the purchasing power of your savings is increasing over time, while a negative real interest rate indicates that the purchasing power of your savings is decreasing over time.

What is the significance of understanding the real interest rate?

Understanding the real interest rate helps us make informed decisions about saving and borrowing. A higher real interest rate incentivizes saving, while a lower real interest rate incentivizes borrowing.

Study Notes

Measuring the Cost of Living

  • Babe Ruth earned $80,000 in 1931. Today's best baseball players earn 200 times that amount. However, rising prices mean comparing income changes without considering price changes gives an incomplete picture of improvement in standard of living.

  • The Consumer Price Index (CPI) tracks changes in the cost of living. Higher CPI means a typical family has to spend more money to maintain the same lifestyle.

  • The CPI is used to monitor the cost of living changes.

  • Inflation is a sustained increase in the general price level of goods and services in an economy.

  • The inflation rate is the percentage change in the price level from one period to the next.

  • The CPI measures the cost of a basket of goods and services bought by a typical consumer.

  • The Bureau of Labor Statistics calculates the CPI monthly.

  • The CPI basket weights goods and services according to consumer spending.

  • CPI calculation steps: choose a base year, fix a representative basket, collect prices for items each year, compute the basket's cost each year, and calculate the CPI.

  • Agencies use the CPI to adjust for inflation.

  • The CPI has limitations: substitution bias, new goods, unmeasured quality change.

  • The GDP deflator considers all domestically produced goods and services. It is the ratio of nominal GDP to real GDP, multiplied by 100.

  • The CPI and GDP deflator can differ. They generally move together but do not always reflect the same change.

  • Prices and inflation affect the value of money.
