19. Phillips Curve Short run trade-off between inflation and unemployment. In the Long Run there is no trade off. The long run Phillips curve is Vertical! Stagflation (an increase in Unemployment and inflation) or an Aggregate Supply Shock will shift the SRPC to the right. Decreases in Inflation and Unemployment will shift the SRPC to the left. (and increase in AS would cause this)
