4. Monetary policy and the Phillips curve The following graph plots the short-run Phillips curve for a hypothetical economy. The given point on the graph indicates the initial rates of unemployment and inflation. Assume that the economy is currently in long-run equilibrium. Suppose the central bank of the hypothetical economy decides to increase the money supply. Oh the following graph, shift the curve or drag the blue polnt along the curve, or do both, to show the short-run e'ects of this policy. Hint: You may assume that the central bank's move was unanticipated. 0 5 ' SR PhillipsCurve 1g" 0 E 4 i e 3 o z 9 ,_ S 2 u. z _ SR Phillips Curve 1 u |. n 2 4 s a 10 12 UNEMPLOYMENT RATE {Percent} In the short run, an unexpected increase in the money supply results in in the inflation rate and in the unemployment rate.
