Result
Your answer: —  Â·  Correct: C
Explanation

The Phillips Curve describes an inverse relationship between the rate of inflation and the rate of unemployment [1]. Statement 1 is correct as it highlights this trade-off, where lower unemployment typically leads to higher inflation [1]. Statement 2 is also correct because this downward-sloping trade-off is generally considered valid only in the short run. In the long run, as inflation expectations adjust, the trade-off disappears [4]. Statement 3 is incorrect because the Long-Run Phillips Curve (LRPC) is characterized as a vertical line, not a horizontal one, at the Non-Accelerating Inflation Rate of Unemployment (NAIRU). At this vertical line, any attempt to reduce unemployment below the NAIRU only results in higher inflation without permanent gains in employment [4]. Therefore, only statements 1 and 2 are true.
