3) Distinguish between the short-run and long-run Phillips curves.
equals the expected inlation rate. There is no long-run tradeof between inlation and
unemployment. The short-run Phillips curve, however, shows the relationship between the
inlation rate and the unemployment rate when the natural unemployment rate and the
expected inlation rate do not change. The short-run Phillips curve is downward sloping, so
that it shows a tradeof between inlation and unemployment.
