Explanation
Taxation's Role in Stimulating Economic Growth
Steps:
- Define economic growth as an increase in real GDP over time, driven by factors like investment, productivity, and labor.
- Identify key drivers: expansions in capital, labor, and technology; policy changes like tax reductions can enhance these.
- Evaluate choices: decreases in employment, investment, or productivity contract output, while tax cuts expand incentives.
- Conclude that reduced taxation aligns with supply-side economics to promote growth.
Why D is correct:
- Decreased taxation increases disposable income and business incentives, boosting investment and consumption per the Laffer Curve principle, which shows optimal tax rates maximize revenue and growth.
Why the others are wrong:
- A: Decreased employment reduces labor input, shrinking potential output in the production function Y = f(K, L, A).
- B: Decreased investment lowers capital stock, slowing long-term growth via the Solow model.
- C: Decreased productivity diminishes efficiency (A in Y = f(K, L, A)), directly contracting GDP.
Final answer: D
