Show Answers

Causes the short-run Phillips curve to shift downward, making the unemployment-inflation trade-off worse.Results in an upward shift of the short-run Phillips curve, improving the unemployment-inflation trade-off.Leads to a downward shift in the short-run Phillips curve, enhancing the unemployment-inflation trade-off.Pushes the short-run Phillips curve upward, causing the unemployment-inflation trade-off to deteriorate.No significant change occurs to the short-run Phillips curve or the unemployment-inflation trade-off.

Explanation

When expected inflation rises, the short-run Phillips curve shifts upward, indicating that for any level of unemployment, inflation is higher. This shift makes the trade-off between unemployment and inflation less advantageous, as reducing unemployment now comes with a higher inflation cost.
