• Benefits may take many years to appear.
• Quality of education matters more than spending alone.

2. Improving Quality, Quantity, and Access to Health Care

Governments improve healthcare systems to increase worker productivity and economic efficiency.

Better healthcare → Healthier workforce → Higher productivity

Explanation:

• Healthy workers are more productive and miss fewer workdays.
• Improved healthcare increases labour force participation.
• Access to healthcare improves quality of life and human capital.

• Healthcare systems require large government expenditure.
• Benefits may take time to appear.
• Inefficient healthcare systems may waste resources.

3. Research and Development (R&D)

Innovation → Higher productivity → Economic growth

Explanation:

• Governments may provide:
  • R&D subsidies
  • Research grants
  • Tax incentives
• Encourages development of new technologies and production methods.
