• Per capita GDP indicates average economic output per person
• GDP growth rate reflects the pace of economic expansion or contraction

Unemployment rate

• Percentage of labor force actively seeking employment but unable to find work

Inflation and Consumer Price Index

• Inflation measures the general increase in prices over time
• Consumer Price Index (CPI) tracks changes in the cost of a basket of goods and services
• Core inflation excludes volatile food and energy prices for a more stable measure
• Federal Reserve targets 2% annual inflation rate for price stability
• Hyperinflation occurs when inflation rates exceed 50% per month, severely devaluing currency

Supply and demand

• Supply and demand form the fundamental framework for understanding market dynamics in the American economy
• These concepts explain how prices are determined and resources are allocated in a market-driven system

Price equilibrium

• Point where supply and demand curves intersect, determining market price
• Equilibrium price balances quantity supplied with quantity demanded
• Surplus occurs when supply exceeds demand, pushing prices down
• Shortage happens when demand exceeds supply, driving prices up
• Market forces naturally move towards equilibrium in absence of external interventions

Elasticity of demand

• Measures responsiveness of demand to changes in price or other factors
• Calculated as $Elasticity = ($
• Elastic demand (luxury goods) highly responsive to price changes
• Inelastic demand (necessities) less responsive to price fluctuations
• Factors affecting elasticity include availability of substitutes, time frame, and proportion of income spent

• Acts as lender of last resort to maintain stability in the financial system

Interest rates and money supply

• Federal funds rate serves as benchmark for other interest rates in the economy

Recession vs depression

• Recession defined as two consecutive quarters of negative GDP growth
• Depressions are prolonged and severe economic downturns (Great Depression of 1930s)
