Study Notes

Inflation, Deflation, and Disinflation

Inflation: Sustained increase in the general price level of goods and services over time, leading to lower purchasing power.
Deflation: Sustained decrease in the general price level of goods and services, resulting in higher purchasing power.
Disinflation: Refers to a decrease in the rate of inflation, indicating slower price increases.

Understanding Rate of Inflation

Inflation denotes an increase in price levels, while the rate of inflation describes the speed at which price levels are rising.
A consistent 5% hike in the price level over two years signifies no change in the inflation rate.
An increase from 5% to 7% in the second year indicates an increased rate of inflation.
A drop in inflation from 10% one year to 7% the next shows disinflation while still having an overall increase in price levels.

Measurement of Inflation & Deflation

Important methods include understanding price indices, calculating consumer price index (CPI), and determining the inflation rate.

Price Index and Index Numbers

Utilize index numbers for comparing data over time, starting with a base year set at an index of 100.
A rise above 100 represents a positive change, while a drop below indicates a negative change.
An index value of 102 equates to a 2% increase from the base year; 97 reflects a 3% decrease from the base year.

Constructing a Price Index

Choose a base year, divide each subsequent year’s price by the base year price, and then multiply by 100.
For example, if 2007 is the base year with a loaf of bread priced at $1.25, it holds an index value of 100.

Price Index Calculation Example

For the years 2007 to 2013, prices and index values can be calculated as follows:
- 2007: Price $1.25, Index 100
- 2011: Price $1.30, Index 104
- 2012: Price $1.40, Index 112
- 2013: Price $1.00, Index 80
Percentage change in price can be calculated using the formula: % Change = (New Index - Old Index) / Old Index x 100.

Percentage Changes

From 2007 to 2012, the price of a loaf of bread increased by 12% (112 - 100).
From 2007 to 2013, the price decreased by 20% (80 from the initial index of 100).

Consumer Price Index (CPI)

CPI measures the change in price level of a basket of consumer goods and services.
CPI uses a base year to compare price changes over time and is an essential tool for assessing inflation rates and economic health.
