Supply-Side Policies Boost Skilled Labor

Steps:

• Identify the goal: increasing skilled labor quantity means expanding workforce education and training.
• Recall policy types: fiscal/monetary target demand; exchange rates affect trade; supply-side targets production factors.
• Match to options: only supply-side directly improves labor skills via incentives like subsidies for training.
• Confirm: this shifts aggregate supply rightward, raising skilled workers.

Why D is correct:

• Supply-side policy, by definition, enhances productive capacity through education, training, and tax incentives for skills development, directly increasing skilled labor quantity.

Why the others are wrong:

• A: Exchange rate policy adjusts currency value to influence exports/imports, not labor skills.
• B: Fiscal policy uses taxes/spending to manage demand and output, ignoring labor quality.
• C: Monetary policy controls money supply and interest rates for inflation/stability, not workforce skills.

Final answer: D
