Key Topics:

• Derived demand for factors
• Labor markets (wage determination, monopsony)
• Capital markets (interest rates, investment)
• Factor mobility and rent

Exam Weight: Approximately 10–15% of the multiple-choice section.

Unit 10: Market Failure and the Role of Government**

This unit addresses situations where markets fail to allocate resources efficiently, including externalities, public goods, and information asymmetry. It evaluates government interventions like taxes, subsidies, and regulation.

Key Topics:

• Positive and negative externalities
• Coase theorem and solutions to externalities
• Public goods and free-rider problem
• Asymmetric information (adverse selection, moral hazard)
• Government policies to correct market failure

Exam Weight: Around 10–15% of the multiple-choice section.

Conclusion

Mastering these units provides a robust framework for analyzing microeconomic behavior and market dynamics.
