- Increased Potential Output: Expansion of the long-run aggregate supply (LRAS) due to enhanced factors of production.
- Time Lags: Supply-side policies may take time to show results, as improvements in productivity and efficiency are gradual.
- Initial Costs: Significant initial investment is often required, which may strain public finances.
- Distributional Effects: Some policies may disproportionately benefit certain sectors or regions, potentially leading to increased inequality.

Effectiveness:
- Market-Based Policies: Effective in promoting competition and efficiency but may require complementary policies to address market failures and ensure equitable outcomes.
- Interventionist Policies: Useful in addressing specific market failures and investing in human capital and infrastructure, but may face challenges related to implementation and cost.
Challenges:
- Implementation: Successful implementation requires careful planning and coordination.
- Impact Measurement: Assessing the impact of supply-side policies can be complex and requires long-term evaluation.
Real-World Examples:
- Deregulation in the UK: The deregulation of industries such as telecommunications and energy in the UK led to increased competition and lower prices for consumers.
