Classifying economic policy types

Steps:

• Training/retraining improves worker skills, boosting labor supply and productivity—supply-side policy.
• Government financing involves public spending, classifying as fiscal policy.
• Policy targets supply capacity, not aggregate demand—demand-side no.
• No central bank tools like interest rates involved—monetary no.

Why D is correct:

• Supply-side policies enhance long-term productive capacity (e.g., human capital via training); fiscal policy encompasses government budget allocations for such expenditures.

Why the others are wrong:

• A: Mislabels as demand-side, which stimulates spending/consumption, not skills.
• B: Falsely tags as monetary, which adjusts money supply/interest rates, irrelevant here.
• C: Identical to D but listed separately; does not alter classification.

Final answer: D
