Final answer:
A rise in consumption spending could move the economy from point E to point H in the short run as it increases aggregate demand, which aligns with the Keynesian Phillips Curve tradeoff between unemployment and inflation. The correct answer is C- Consumption spending rises.
Step-by-step explanation:
The event that could lead the economy to move to point H in the short run, given an initial actual and expected inflation rate of 6% and an unemployment rate of 5%, would be option C- Consumption spending rises.
This scenario aligns with the Keynesian Phillips Curve, which illustrates a tradeoff between the unemployment rate and the inflation rate.
A rise in consumption spending would increase aggregate demand, potentially decreasing unemployment and increasing inflation in the short run, thus moving the economy from point E to point H on the Phillips Curve diagram.
It's important to note that while the Phillips Curve suggests this short-run tradeoff, theories also acknowledge adjustments over time; persistent efforts to lower unemployment below the natural rate could lead to accelerating inflation without achieving permanently lower unemployment rates.
