  1. April 14, 2014 • The Phillips Curve • Return & Review Fiscal Policy FRQ Quiz & Unit Exam • Unit Study Guide • Return All Other work Unit IV Exam: Thursday, April 17.

  2. The Phillips Curve • Shows the inverse relationship between the unemployment rate and the inflation rate.

  3. DEMAND-PULL INFLATION “Too many dollars chasing too few goods” • DEMAND PULLS UP PRICES!!! • Demand increases but supply stays the same.

  4. COST-PUSH INFLATION Higher production costs increase prices! A negative supply shock increases the costs of production and forces producers to increase prices.

  5. Lower unemployment = higher inflation • Higher inflation = lower unemployment. REPRESENTED BY THE PHILLIPS CURVE

  6. Positive and Negative Supply Shocks Shift SRPC When SRAS increases along with AD, both the unemployment and inflation rates fall. This is seen as a downward shift of the SRPC. When SRAS decreases along the AD, both the unemployment and inflation rates rise. This is seen as an upward shift of the SRPC.

  7. Short-Run Phillips Curve • Positive Supply Shock brings both lower inflation lower unemployment • A Negative Supply Shock will bring higher inflation and higher unemployment

  8. The Short-Run Phillips Curve and Supply Shocks

  9. Long Run Phillips Curve • LRPC represents the relationship between unemployment and inflation AFTER the economy has adjusted to inflationary expectations. • The LRPC occurs at the Nonaccelerating Inflation Rate of Unemployment (NAIRU.) • NAIRU: Unemployment rate which DOES NOT CAUSE INFLATION TO INCREASE. • NAIRU = LRPC • NAIRU: Full employment output and Natural Rate of Unemployment (NRU)

  10. Expected Inflation will directly affect the present inflation rate • What determines expected inflation? • The expected rate of inflation is the rate that employers and workers expect in the near future. • An increase in expected inflation shifts the short – run Phillips Curve upward

  11. LONG RUN PHILLIPS CURVE The short run and long run effects of expansionary policies

  12. Most macroeconomists believe that there is no long-run trade-off between lower unemployment rates and higher inflation rates. That is, it is not possible to achieve lower unemployment in the long run by accepting higher inflation.

  13. LONG RUN PHILLIPS CURVE • NAIRU • LRPC • Natural Rate Hypothesis • Natural Rate = NAIRU

  14. The unemployment rate at which inflation does not change over time—5% in the previous graph, is known as the non-accelerating inflation rate of unemployment, or NAIRU for short. • Keeping the unemployment rate below the NAIRU leads to ever­-­accelerating inflation and cannot be maintained and therefore there is no long­run trade­off between unemployment and inflation.

  15. DISINFLATION WILL EVENTUALLY BRING HIGH UNEMPLOYMENT

  16. Expected Inflation and the Short-Run Phillips Curve
