Government Budget, Fiscal Policy, Deficit Financing & Multipliers

TAKEAWAYS:

• Fiscal policy uses government spending (G) and taxes (T) to stabilize economies, while deficit financing bridges gaps when revenue falls short.
• Multipliers (investment, tax, government) amplify initial changes in spending or taxes by 1/(1-MPC)—a key exam calculation.
• Nepal’s 15th Plan (2019–2024) relies on fiscal policy to fund infrastructure (e.g., roads, hydropower) and social programs (e.g., free education).
• Crowding-out effect occurs when government deficits raise interest rates, reducing private investment (seen in Nepal’s bond market).
• Automatic stabilizers (e.g., unemployment benefits) work without policy changes, while discretionary policies require deliberate action.
• Exam focus: Derive multipliers from structural equations, compute equilibrium income, and analyze policy impacts on GDP/inflation.

1. Government Budget: Revenue, Expenditure, and Deficits

Government budgets are the financial blueprint of a nation, balancing revenue (taxes, fees, grants) and expenditure (infrastructure, defense, subsidies). When expenditure > revenue, a budget deficit arises, financed via:

• Domestic borrowing (bonds, treasury bills).
• Foreign loans (e.g., World Bank, ADB).
• Printing money (risking inflation).

Why Deficits Matter

• Short-term: Funds infrastructure (e.g., Nepal’s 1000 MW West Seti Hydropower Project).
• Long-term: Risk of debt traps (e.g., Sri Lanka’s 2022 crisis).
• Nepal’s Deficit: ~4% of GDP (FY 2023), financed via T-bills and foreign aid.

2. Fiscal Policy: Tools and Objectives

Fiscal policy adjusts G and T to achieve:

1. Economic growth (via stimulus spending).
2. Price stability (via tax hikes to curb demand-pull inflation).
3. Full employment (via job-creating public works).

Tools

Real-World Example: Daraz’s Fiscal Stimulus

During COVID-19, Nepal’s government increased G by Rs. 50B to support Daraz (Alibaba’s Nepal arm) with:

• Subsidized loans for sellers.
• Cash transfers to low-income shoppers. Result: Daraz’s GMV grew 30% YoY (2021), but also crowded out private lenders (interest rates rose).

3. Multipliers: How Small Changes Create Big Impacts

Multipliers measure how an initial change in spending/taxes ripples through the economy. The keynesian multiplier formula:

$$\text{Multiplier}=\frac{1}{1-\text{MPC}}$$ where MPC (Marginal Propensity to Consume) = ΔC/ΔY.

Types of Multipliers

WORKED EXAMPLE: Nepal’s 2023 Fiscal Stimulus Given:

• MPC = 0.75 (Nepal’s average consumption rate).
• Government increases G by Rs. 100B.

Step 1: Calculate the government expenditure multiplier. $$k_G=\frac{1}{1-0.75}=4$$

Step 2: Compute the total GDP change. $$\Delta Y=k_G\times \Delta G=4\times 100B=\text{Rs. 400B GDP increase}$$

Real Tie-In: This mirrors Nepal’s post-earthquake (2015) reconstruction spending, which boosted GDP by ~3% but also increased inflation to 8.5% (2016).

4. Deficit Financing: Methods and Risks

When T < G, governments finance deficits via:

Crowding-Out Effect

When deficits increase demand for loans, interest rates rise, reducing private investment. Example: Nepal’s 2022 bond issuance pushed corporate loan rates to 12% (from 9% in 2021), hurting SMEs like local textile mills.

5. Automatic vs. Discretionary Fiscal Policy

6. Fiscal Policy in Nepal: Case Study

Scenario: Nepal’s 15th Plan (2019–2024) aims to graduate to middle-income status by 2050. Key fiscal moves:

1. Increased G by 20% (from Rs. 1.2T to Rs. 1.44T) for:
   • Infrastructure: Rs. 500B for transit-oriented development (TOD) in Kathmandu.
   • Social spending: Rs. 300B for free education (Class 1–12).
2. Tax reforms:
   • VAT hike from 13% to 18% (2022) to curb deficits.
   • Digital tax incentives for eSewa/Khalti transactions (now 60% of Nepal’s tax revenue comes from digital payments).

Outcome:

• GDP growth: 5.5% (2023) vs. 2.5% pre-pandemic.
• Inflation: 8.2% (2023) due to demand-pull effects of stimulus.

In the Real World

1. eSewa’s Tax Collection (MPC & Multipliers)

   • When eSewa reduced transaction fees by 1% (2023), users spent 15% more (MPC = 0.15).
   • Multiplier effect: Rs. 100M fee cut → Rs. 1.15B extra spending in Nepal’s economy.
   • Policy link: Government subsidized eSewa’s fee cuts to boost digital payments (now 80% of Nepal’s retail transactions).

2. Pathao’s Fiscal Stimulus (Government Multiplier)

   • During COVID, Nepal’s government gave Pathao Rs. 50B to subsidize last-mile delivery for essentials.
   • Result: Pathao’s driver earnings rose 40%, and GDP grew by Rs. 200B (multiplier = 4, assuming MPC = 0.75).

3. NTC’s Crowding-Out (Deficit Financing Risk)

   • NTC’s Rs. 300B expansion plan (2023) required borrowing, pushing interbank rates to 10%.
   • Impact: Private telecom firms (e.g., Smart Cell) cut capex by 30%, delaying 5G rollout.

Exam Tip

1. Derive Multipliers from Scratch

   • Always start with equilibrium: $Y=C+I+G+(X-M)$.
   • Substitute structural equations (e.g., $C=a+b{Y}_d$) and solve for $Y$.
   • Example: Given $C=200+0.7(Y-T)$, $T=500+0.2Y$, find $k_G$.

2. Compute Equilibrium Income

   • Step 1: Write all equations in terms of $Y$.
   • Step 2: Solve for $Y$ using substitution.
   • Step 3: Plug $Y$ back to find savings, taxes, or trade balance.

3. Policy Analysis Questions

   • If GDP is too low: Recommend ↑G or ↓T (expansionary).
   • If inflation is high: Recommend ↓G or ↑T (contractionary).
   • Always mention trade-offs: E.g., "While ↑G boosts jobs, it may crowd out private investment."

4. Nepal-Specific Tips

   • Use real data: Memorize Nepal’s MPC (~0.7–0.8), tax-to-GDP ratio (~15%), and deficit (~4% of GDP).
   • Link to plans: Refer to 15th Plan’s Rs. 1.44T budget or post-earthquake reconstruction.
   • Inflation connection: If asked about fiscal policy, always discuss inflation risk (e.g., "↑G may push inflation to 9% as seen in 2016").

WORKED EXAM QUESTION Question: Derive the investment multiplier and compute equilibrium income for Nepal’s economy with:

• $C=300+0.8(Y-T)$
• $T=120+0.2Y$
• $I=400$
• $G=500$
• $X=100$, $M=50+0.1Y$

Solution:

1. Find MPC: $\text{MPC}=0.8$ (from $C$ equation).
2. Calculate multiplier: $k=\frac{1}{1-0.8}=5$.
3. Equilibrium condition: $Y=C+I+G+(X-M)$. Substitute all equations and solve: $$Y=[300+0.8(Y-120-0.2Y)]+400+500+[100-(50+0.1Y)]$$ Simplify: $$Y=300+0.8Y-96-0.16Y+400+500+50-0.1Y$$ $$Y=1,054+0.54Y$$ $$0.46Y=1,054⟹Y=\text{Rs. 2,291.3B}$$ Answer: Equilibrium income = Rs. 2,291.3 billion.
