What Does Inflation Mean?
The rate at which the general level of prices for goods and services is rising, and, subsequently, purchasing power is falling. Central banks attempt to stop severe inflation, along with severe deflation, in an attempt to keep the excessive growth of prices to a minimum.

Inflation: How Is It Measured?

Measuring inflation is a difficult problem for government statisticians. To do this, a number of goods that are representative of the economy are put together into what is referred to as a "market basket." The cost of this basket is then compared over time. This results in a price index, which is the cost of the market basket today as a percentage of the cost of that identical basket in the starting year.


In North America, there are two main price indexes that measure inflation:
• Consumer Price Index (CPI) - A measure of price changes in consumer goods and services such as gasoline, food, clothing and automobiles. The CPI measures price change from the perspective of the purchaser. U.S. CPI data can be found at the Bureau of Labor Statistics.
• Producer Price Indexes (PPI) - A family of indexes that measure the average change over time in selling prices by domestic producers of goods and services. PPIs measure price change from the perspective of the seller. U.S. PPI data can be found at the Bureau of Labor Statistics.
What causes a recession?

According to the National Bureau of Economic Research (NBER), recession is defined as "a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real gross domestic product (GDP), real income, employment, industrial production and wholesale-retail sales". More specifically, recession is defined as when businesses cease to expand, the GDP diminishes for two consecutive quarters, the rate of unemployment rises and housing prices decline.

Many factors contribute to an economy's fall into a recession, but the major cause is inflation. Inflation refers to a general rise in the prices of goods and services over a period of time. The higher the rate of inflation, the smaller the percentage of goods and services that can be purchased with the same amount of money. Inflation can happen for reasons as varied as increased production costs, higher energy costs and national debt.

In an inflationary environment, people tend to cut out leisure spending, reduce overall spending and begin to save more. But as individuals and businesses curtail expenditures in an effort to trim costs, this causes GDP to decline. Unemployment rates rise because companies lay off workers to cut costs. It is these combined factors that cause the economy to fall into a recession.
