MEcon Master of Economics Public Finance and Fiscal Policy 2 — Questions and Answers
Question 1: The Laffer Curve illustrates the relationship between tax rates and:
- Tax revenue (Correct answer)
- Income inequality
- Government expenditure
- Economic growth
Correct answer: Tax revenue
The Laffer Curve shows that tax revenue is zero at both 0% and 100% rates, with a revenue-maximizing rate in between, implying that very high rates can reduce revenue.
Question 2: Crowding out in fiscal policy refers to:
- Government spending displacing private consumption directly
- Deficit-financed spending raising interest rates and reducing private investment (Correct answer)
- Tax cuts stimulating private spending
- Government borrowing from the central bank
Correct answer: Deficit-financed spending raising interest rates and reducing private investment
When the government borrows to finance deficits, it increases demand for loanable funds, pushing interest rates up and discouraging private investment.
Question 3: Which of the following best describes the concept of 'tax incidence'?
- The legal obligation to pay a tax
- The actual economic burden of a tax and how it is distributed between buyers and sellers (Correct answer)
- The revenue collected by the government from a tax
- The tax rate applied to the highest income bracket
Correct answer: The actual economic burden of a tax and how it is distributed between buyers and sellers
Tax incidence analysis identifies who ultimately bears the cost of a tax in terms of reduced purchasing power, which depends on the price elasticities of supply and demand.
Question 4: In public finance, the benefit principle of taxation holds that:
- Taxes should be progressive to reduce inequality
- People should pay taxes in proportion to the benefits they receive from government services (Correct answer)
- Taxes should be levied on corporations rather than individuals
- All citizens should pay the same flat tax rate
Correct answer: People should pay taxes in proportion to the benefits they receive from government services
The benefit principle links tax liability to public service consumption, providing a market-like rationale for taxation and aligning with Wicksellian voluntary exchange theory.
Question 5: The Ramsey optimal tax rule suggests that, to minimize efficiency losses, tax rates should be:
- Equal across all goods
- Inversely proportional to price elasticity of demand (Correct answer)
- Higher on necessities than luxuries
- Based on income levels of consumers
Correct answer: Inversely proportional to price elasticity of demand
Ramsey's inverse elasticity rule minimizes deadweight loss by taxing goods with inelastic demand more heavily, as their quantities don't distort much in response.
Question 6: Intergovernmental fiscal transfers (grants) are used in federal systems primarily to:
- Reduce the federal government's budget deficit
- Correct fiscal imbalances between levels of government and address spillovers (Correct answer)
- Give states the power to set federal tax rates
- Eliminate all subnational government borrowing
Correct answer: Correct fiscal imbalances between levels of government and address spillovers
Grants address vertical fiscal imbalances (the mismatch between revenue-raising capacity and spending responsibilities) and horizontal spillovers (when one jurisdiction's services benefit residents elsewhere).
