Public Finance: Taxes, Expenditure & Government Role

TAKEAWAYS:

• Public finance is about how governments collect revenue and spend it for the public good.
• Taxes are the main source of government revenue, but fees, fines, and borrowings also help.
• Government expenditure can be classified into revenue expenditure and capital expenditure.
• Public goods are services that the government provides because private markets cannot.
• Nepal’s public finance includes taxes like VAT, income tax, and customs duties.
• Understanding public finance helps explain why governments exist and how they impact our daily lives.

What is Public Finance?

Public finance is the study of how governments raise money (revenue) and spend it (expenditure) to achieve economic and social goals. It includes:

• Revenue: Money the government collects (taxes, fees, borrowings).
• Expenditure: Money the government spends (public goods, welfare, infrastructure).
• Public debt: Money borrowed by the government that must be repaid with interest.

Why is Public Finance Important?

• Governments provide services that private markets cannot (e.g., roads, defense, education).
• Taxes help reduce inequality by redistributing wealth.
• Government spending can boost economic growth (e.g., building schools or hospitals).

Sources of Government Revenue

Governments collect money from different sources. The main ones are:

1. Taxes

Taxes are compulsory payments to the government. They can be:

• Direct taxes: Paid directly to the government (e.g., income tax, property tax).
• Indirect taxes: Paid indirectly through goods and services (e.g., VAT, customs duties).

  C --> F["VAT: Value-Added Tax on sales"]

2. Fees and Fines

• Fees: Payments for specific services (e.g., school fees, driving license fees).
• Fines: Penalties for breaking laws (e.g., traffic fines, late payment fines).

3. Borrowings (Public Debt)

Governments borrow money by issuing bonds or taking loans. This creates public debt, which must be repaid with interest. Example:

• Nepal’s government borrows money from international organizations like the World Bank or Asian Development Bank (ADB) to fund large projects (e.g., roads, hospitals).

Types of Taxes in Nepal

Nepal’s government collects taxes through different sources. Here are the key ones:

Government Expenditure

Government spending can be divided into two main types:

1. Revenue Expenditure

Money spent on day-to-day running of the government. It does not create assets. Examples:

• Salaries of government employees (teachers, police, doctors).
• Maintenance of roads, schools, and hospitals.
• Subsidies (e.g., fuel subsidies, agricultural subsidies).

2. Capital Expenditure

Money spent on long-term projects that create assets. Examples:

• Building new roads, bridges, or hospitals.
• Buying machinery or equipment for public use.
• Investing in infrastructure (e.g., hydropower projects).

Public Goods

Public goods are services that:

1. Are non-excludable (everyone can use them, even if they don’t pay).
2. Are non-rivalrous (one person’s use does not reduce another’s use).

Examples:

• National defense: Protects all citizens, whether they pay taxes or not.
• Public parks: Anyone can use them without reducing their availability.
• Street lighting: Benefits everyone in the area.

Why can’t private markets provide public goods?

• Free-rider problem: People may refuse to pay but still benefit.
• High costs: Private companies may not find it profitable to provide them.

Merit Goods

Merit goods are services that the government provides because they are socially desirable but may be underprovided by the market. Examples:

• Education: The government builds schools and provides scholarships.
• Healthcare: Public hospitals provide affordable medical services.
• Clean water: The government ensures access to safe drinking water.

Why does the government provide merit goods?

• Private markets may not provide enough (e.g., poor people cannot afford education).
• These goods improve the overall welfare of society.

Demerit Goods

Demerit goods are harmful to individuals and society but are often overconsumed because their costs are not fully visible. Examples:

• Tobacco and alcohol: Cause health problems but are heavily consumed.
• Drugs: Harmful but illegally traded.

How does the government control demerit goods?

• Taxation: High taxes on cigarettes and alcohol (e.g., excise duty).
• Regulation: Banning or restricting sales (e.g., age limits for alcohol).
• Public awareness campaigns: Educating people about the harms.

Government Budget

A government budget is a financial plan that shows:

• Revenue: How much money the government expects to collect.
• Expenditure: How much money the government plans to spend.
• Deficit or Surplus: The difference between revenue and expenditure.

Types of Budgets:

1. Balanced Budget: Revenue = Expenditure.
2. Budget Deficit: Expenditure > Revenue (government borrows money).
3. Budget Surplus: Revenue > Expenditure (government saves money).

Public Debt

Public debt is the total amount of money a government owes to lenders. It includes:

• Internal debt: Borrowed from within the country (e.g., bonds sold to Nepali citizens).
• External debt: Borrowed from foreign sources (e.g., loans from the World Bank).

Advantages of Public Debt:

• Helps fund large projects (e.g., infrastructure, education).
• Can stimulate economic growth during recessions.

Disadvantages of Public Debt:

• Increases the debt burden: Future generations may have to repay it.
• High interest payments can reduce funds for other important services.
• May lead to inflation if the government prints more money to repay debts.

Example in Nepal:

• Nepal’s public debt has been increasing due to infrastructure projects and economic challenges.
• The government borrows from international organizations like the ADB and World Bank.

Taxation and Economic Efficiency

Taxes can affect how people and businesses behave. Good taxation should:

1. Be fair (people pay according to their ability).
2. Be simple (easy to understand and collect).
3. Be efficient (low cost to collect).
4. Not distort economic decisions too much.

Types of Tax Incidence:

• Direct incidence: Who legally pays the tax (e.g., a company pays VAT).
• Indirect incidence: Who actually bears the burden (e.g., consumers pay higher prices due to VAT).

Example: If the government increases VAT on mobile phones, the legal incidence is on the phone company, but the economic incidence falls on consumers (higher prices).

Solved Example: Calculating Tax Revenue

Question: If the government imposes a 10% VAT on a product priced at Rs. 1,000, how much VAT is collected if 1,000 units are sold?

Solution:

1. VAT per unit = 10% of Rs. 1,000 = $\frac{10}{100}\times 1000=Rs.100$.
2. Total VAT collected = VAT per unit × Number of units = $100\times 1000=Rs.100,000$.

Answer: Rs. 100,000.

Solved Example: Government Budget Deficit

Question: If Nepal’s government plans to spend Rs. 500 billion but expects to collect only Rs. 450 billion in taxes, what is the budget deficit?

Solution: Budget deficit = Expenditure – Revenue = $500-450=Rs.50$ billion.

Answer: Rs. 50 billion deficit.
