AP Economics Mr. Bernstein Module 14: Inflation: An Overview February 11, 2014
AP EconomicsMr. Bernstein Inflation: An Overview • Objectives - Understand each of the following: • The economic costs of inflation • How inflation creates winners and losers • Why policy makers try to maintain a stable rate of inflation • The difference between real and nominal values of income, wages and interest rates • The problems of deflation and disinflation
AP EconomicsMr. Bernstein Price Levels don’t matter, Relative Prices do • If the price of gas doubles, one can only drive half as much…unless income also doubles!...in this case real income was flat • The rate of change is therefore important, not the absolute value of price changes
AP EconomicsMr. Bernstein Price Levels don’t matter, Relative Prices do • Inflation rate = (Price level, year 2 – Price level, year 1) / (Price level, year 1) x 100 • Costs of inflation • Shoe leather costs • Effort spent by consumers seeking lower prices or substitutes • Menu costs • Effort spent by businesses realigning pricing strategies • Unit of Account costs • Tax increases based on inflating asset values may not be matched by income increases
AP EconomicsMr. Bernstein Winners and Losers from Inflation • Borrowers pay back loans in dollars with reduced purchasing power • Nominal Interest Rates = Real Interest Rates + Expected Inflation • So when inflation exceeds expectations, the borrower benefits; when inflation is below expectations, the lender benefits • Inflation can redistribute income from those that are hurt by rising prices to those who gain from rising prices
AP EconomicsMr. Bernstein Inflation is Easy; Disinflation is hard • Inflation is a rise in overall price levels • Deflation is a decline in overall price levels • Disinflation is the reduction in inflation rates • Most obvious policy to bring about disinflation is Monetary Policy (reduce money supply) • Can be painful because it causes a reduction in the demand for goods and services, which in turn causes a reduction in demand for labor
