B
Answer to Question 2
Contractionary monetary policy reduces the inflation rate. With adaptive expectations, workers and firms will overestimate inflation, resulting in an increase in the real wage and an increase in the unemployment rate (move from A to B on the short-run Phillips curve below). Eventually, workers and firms will adjust to the fact that inflation is lower, shifting the short-run Phillips curve down and reducing the unemployment rate to its natural rate (move from B to C in the graph below).
