Long Descriptive Questions

1. **Explain the key principles of Classical Economics and

discuss its relevance in today’s economic environment.**

• Answer: Classical economics, led by Adam Smith, emphasizes the idea of a self-regulating market driven by individual interests. It believes in minimal government intervention and supports free-market capitalism. While the classical model works well in an idealized market, real-world issues like unemployment, market failures, and externalities necessitate government involvement, making it less applicable in modern economies.

2. Discuss the key ideas behind Keynesian economics and how they influence modern fiscal policies.
   • Answer: Keynesian economics focuses on aggregate demand as the driver of economic activity and emphasizes the need for government intervention, especially in times of recession. Keynes advocated for increased government spending and reduced taxes to stimulate demand and pull economies out of depression. Modern fiscal policies, including stimulus packages during recessions, draw heavily from Keynesian ideas.
