For this question, assume that the Phillips curve equation is represented by the following: πt − πt−1 = (m + z) − αut. Which of the following will cause a reduction in the natural rate of unemployment? (a) an increase in m (b) an increase in z (c) an increase in α (d) an increase in actual inflation (e) an increase in expected inflation

Correct option is C

Explanation:

Increase in \alpha decreases πt - π(t-1) which shows decrease in natural rate of unemployment.

Phillips bend clarifies the connection between expansion rate and joblessness rate. As indicated by it there is a reverse connection between the joblessness rate and swelling rate. It implies there is an exchange off among expansion and joblessness rate.  

The strategy ramifications of Phillips bend is that administration can't lessen swelling and joblessness together. It joblessness decreases, at that point the economy must acknowledge higher expansion. Then again, on the off chance that economy lessens expansion, at that point it must acknowledge higher joblessness.  

When there is synchronous change in the swelling rate and joblessness rate then this is an instance of development along the short-run Phillips bend.  

Then again, when either joblessness rate or swelling rate stays unaltered while different changes then it prompts moving of short-run Phillips bend.

going on the gulag might you to find a better answer for that problem
