CLEP Macroeconomics covers the principles of macroeconomic theory, including national income, inflation, and fiscal policy.
Inflation is the general increase in prices over time. When inflation is high, each dollar buys less than before, which is called a loss of purchasing power.
Economists use price indexes like the Consumer Price Index (CPI) to track inflation. The inflation rate is the percentage change in these indexes over time.
Some inflation is normal and signals a growing economy, but too much can hurt savings and disrupt spending plans.
Central banks, like the Federal Reserve, often aim for around 2% inflation per year.
If a candy bar cost $1 last year and $1.10 this year, inflation is 10%.
Hyperinflation in Zimbabwe once led to prices doubling every day.
Inflation means prices are rising, making money less valuable over time.
