Download PDF Past Paper On Public Policy Economics For Revision
Public Policy Economics (often referred to as Public Economics) examines the role of the government in the economy. It focuses on how the state should intervene to correct Market Failures, how it should raise revenue through Taxation, and how it should allocate resources to improve Social Welfare. To excel in this exam, you must demonstrate a mastery of the Efficiency vs. Equity trade-off and be able to provide a rigorous economic justification for policies ranging from healthcare subsidies to carbon taxes.

Public Policy Economics: Key Revision Q&A
Q1: What is “Market Failure” and why does it justify policy?
A: Market failure occurs when the free market, left to itself, fails to allocate resources efficiently ($P \neq MC$). The primary justifications for government policy include:
-
Externalities: When a transaction affects a third party (e.g., pollution).
-
Public Goods: Goods that are non-excludable and non-rivalrous (e.g., national defense).
-
Asymmetric Information: When one party knows more than the other (e.g., health insurance).
-
Monopoly Power: When a single firm restricts output to raise prices.
Q2: Contrast “Public Goods” vs. “Common Resources.”
A: These are categorized by two characteristics:
-
Public Goods: Non-rival (my use doesn’t stop yours) and Non-excludable (can’t stop people from using it). These suffer from the Free-Rider Problem.
-
Common Resources: Rival (my use reduces yours) but Non-excludable (e.g., fish in the ocean). These suffer from the Tragedy of the Commons.
Q3: Explain “The Coase Theorem” in Policy.
A: Proposed by Ronald Coase, this suggests that if property rights are well-defined and transaction costs are zero, private parties can bargain to solve the problem of externalities without government intervention.
-
Exam Application: You may be asked why this theorem often fails in the real world (e.g., high legal fees or too many affected parties).
Q4: What is “Tax Incidence” and how is it determined?
A: Tax incidence refers to who actually bears the burden of a tax—the buyer or the seller.
-
The Rule: The burden falls more heavily on the side of the market that is more Inelastic.
-
If demand is inelastic (e.g., cigarettes), the consumer pays most of the tax. If supply is inelastic, the producer bears the burden.
Q5: Describe “Cost-Benefit Analysis” (CBA) in Public Projects.
A: Governments use CBA to decide if a project is worth the investment.
-
Net Present Value (NPV): Future benefits and costs must be “discounted” to their present value.
-
Social Discount Rate: A critical exam topic—choosing a rate that balances the needs of the current generation with those of future generations.
Why Practice with Public Policy Past Papers?
Public policy exams are Evaluative and Normative. You won’t just list taxes; you will be given a social problem (e.g., “Rising obesity rates”) and asked to “Design an Optimal Tax that minimizes Deadweight Loss” or “Evaluate the Equity Impacts of a universal basic income versus targeted welfare.”
By practicing with our past papers, you will:
-
Master Welfare Economics: Practice using Social Welfare Functions (Utilitarian vs. Rawlsian) to compare different policy outcomes.
-
Refine Taxation Logic: Learn the difference between Progressive, Proportional, and Regressive tax systems.
-
Understand Public Choice Theory: Practice explaining why “Government Failure” (e.g., corruption or rent-seeking) might be worse than market failure.
