Geno Potosi is delivering a lecture on the Phillips curve model, during which he makes the following two statements: Statement 1: If expected inflation is less than actual inflation, the short-run Phillips curve shows that the unemployment rate will increase. Statement 2: The negative relationship between the inflation rate and unemployment rate does not hold in the long run because the expected inflation rate adjusts to the actual performance of inflation. Are Potosi’s two statements correctStatement 1Statement 2()①A. Correct Correct ②B. Incorrect Correct ③C. Correct Incorrect
A. ①
B. ②
C. ③
参考答案:B
解析:
Statement 1 is incorrect. If actual inflation is greater than expected inflation, such as would occur in the case of a greater-than-expected increase in aggregate demand, the unemployment rate decreases in the short run. Statement 2 is correct. The short-run difference between expected and actual inflation is the source of the short-run negative relationship between inflation and unemployment.
