#13
Which economist is credited with introducing the concept of the Phillips Curve?

#16
Which of the following best describes the relationship between the Phillips Curve and the concept of potential output?
Potential output is the point where the Phillips Curve intersects with zero inflation
Potential output is the level of output where the Phillips Curve intersects with the natural rate of unemployment

#23
What effect does an increase in aggregate demand have on the Phillips Curve in the short run?

#25
What role does the expectations-augmented Phillips Curve play in explaining stagflation?
It suggests that higher inflation can lead to lower unemployment in the long run
It suggests that expectations of higher inflation can cause higher inflation itself
It suggests that the natural rate of unemployment is constant over time
It suggests that monetary policy is ineffective in controlling inflation
