Inflation: Causes, Types, Policy Responses & Nepal’s Reality

TAKEAWAYS:

• Inflation is a sustained rise in the general price level (measured by GDP deflator or CPI), eroding purchasing power—Nepal’s 2023 inflation hit 8.1% (Nepal Rastra Bank).
• Demand-pull inflation occurs when aggregate demand outpaces supply (e.g., Daraz’s Black Friday sales surge), while cost-push inflation stems from rising production costs (e.g., NTC’s fuel price hikes after global oil shocks).
• Monetary policy (interest rates, open-market operations) and fiscal policy (taxes, government spending) are the two main tools to curb inflation—Nepal Rastra Bank raised repo rates to 7.5% in 2023 to combat inflation.
• Hyperinflation (prices doubling monthly) destroys savings (e.g., Zimbabwe 2008) and requires drastic measures like currency reform or dollarization.
• Wage-price spiral: Rising wages → higher production costs → higher prices → demand for higher wages (seen in Nepal’s informal sector like Kathmandu’s rickshaw drivers).
• Inflation’s winners/losers: Fixed-income groups (pensioners) lose, while debtors (home loan borrowers) gain—Nepal’s senior citizens saw real income drop by 15% in 2023.

1. What Is Inflation?

Inflation is the persistent increase in the general price level of goods and services over time, reducing the purchasing power of money. It is measured using:

• GDP Deflator: $(\frac{\text{Nominal GDP}}{\text{Real GDP}})\times 100$
• Consumer Price Index (CPI): Basket of goods (food, housing, transport) weighted by consumption patterns.

How Inflation Works: A Real Example

In Nepal, the CPI-based inflation rate averaged 7.8% in FY 2022/23 (Nepal Rastra Bank). Let’s trace how this affects a fixed-income family earning Rs. 50,000/month:

• 2022: Rs. 50,000 buys 10 kg rice (Rs. 500/kg).
• 2023: Rice price rises to Rs. 600/kg due to supply chain disruptions (floods in Terai). Now, Rs. 50,000 buys only 8.3 kg rice—a 17% real income loss.

2. Causes of Inflation: Demand-Pull vs. Cost-Push

Inflation arises from excess demand or rising costs. The two primary types:

A. Demand-Pull Inflation

Occurs when aggregate demand (AD) > aggregate supply (AS) at the full-employment level of output. Causes:

• High consumer spending (e.g., eSewa’s surge in online payments post-pandemic).
• Government stimulus (e.g., Nepal’s Rs. 100 billion COVID relief packages in 2020).
• Investment booms (e.g., Daraz’s expansion leading to higher demand for logistics).
• Speculative demand (e.g., hoarding of essentials like sugar during festivals).

Real-World Example: eSewa’s Role in Demand-Pull Inflation

• Pre-2020: Cash transactions dominated; inflation was ~5%.
• Post-2020: eSewa transactions surged 500% (from Rs. 50B to Rs. 250B/month). Higher digital payments → increased velocity of money → higher aggregate demand → price hikes (e.g., mobile tariffs rose 20% in 2021).

B. Cost-Push Inflation

Occurs when production costs rise, forcing firms to increase prices. Causes:

• Rise in wages (e.g., NTC workers’ strike in 2023 → higher labor costs → higher electricity tariffs).
• Increase in raw material prices (e.g., global wheat prices up 30% post-Ukraine war → Nepal’s flour prices rose 25%).
• Higher taxes (e.g., Nepal’s 13% VAT increase in 2022 on luxury goods).
• Natural disasters (e.g., 2022 floods in Terai → 30% drop in rice output → price surge).

Visual: Cost-Push Inflation

Real-World Example: NTC’s Fuel Price Hike (2023)

• Cause: Global oil prices rose 40% due to Russia-Ukraine war.
• Effect: NTC increased petrol price by Rs. 15/L and diesel by Rs. 20/L.
• Impact:
  • Transport costs for Daraz/Pathao rose 25% → higher delivery fees.
  • Manufacturing costs for cement, textiles, and food surged → wholesale price index (WPI) rose 12%.

3. Other Types of Inflation

4. Measuring Inflation: GDP Deflator vs. CPI

Worked Example: Calculating Inflation Rate Given:

• GDP Deflator (2023) = 375
• GDP Deflator (2024) = 405

Inflation Rate = (( \frac{405 - 375}{375} ) \times 100 = 8%

5. Effects of Inflation

A. Positive Effects (Moderate Inflation)

• Encourages spending: People buy now to avoid future price hikes.
• Reduces debt burden: Borrowers repay with cheaper money (e.g., home loans in Nepal).
• Stimulates investment: Businesses expand expecting higher profits.

B. Negative Effects (High Inflation)

6. Controlling Inflation: Monetary and Fiscal Policies

A. Monetary Policy Tools (Nepal Rastra Bank’s Arsenal)

B. Fiscal Policy Tools (Government’s Role)

Worked Example: Fiscal Policy Impact

• Scenario: Nepal’s government reduces infrastructure spending by Rs. 50B (from Rs. 200B to Rs. 150B).
• Effect:
  • AD falls by Rs. 50B → price level drops by ~2% (assuming price elasticity of demand = 0.5).
  • Inflation rate reduces from 8.1% to 6.1%.

7. Special Cases: Wage-Price Spiral and Hyperinflation

A. Wage-Price Spiral

A vicious cycle where:

1. Workers demand higher wages due to inflation.
2. Firms raise prices to cover wage hikes.
3. Workers demand even higher wages → repeat.

Nepal Example: Informal Sector (Rickshaw Pullers)

• 2022: Inflation at 7.2% → rickshaw pullers demand Rs. 500/day (up from Rs. 400).
• 2023: Firms raise fare by 10% → pullers demand Rs. 550/day → cycle repeats.

B. Hyperinflation: Nepal’s Near-Miss in 1990s

• Cause: Excess money printing to fund civil war costs (1996–2006).
• Peak: Monthly inflation hit 30% in 1994.
• Solution: Currency reform (1993) → introduced new Nepalese Rupee (1 old = 1 new).

## In the Real World

1. eSewa’s Role in Demand-Pull Inflation

   • Idea Used: Increased velocity of money (digital payments boost AD).
   • How: Post-pandemic, eSewa transactions surged 500%, injecting liquidity into the economy. Higher demand for goods/services → price hikes (e.g., mobile recharge prices up 20% in 2021).

2. NTC’s Fuel Price Hikes (Cost-Push Inflation)

   • Idea Used: Supply shock → cost-push inflation.
   • How: Global oil prices rose 40% → NTC increased petrol by Rs. 15/L. This raised transport costs for Pathao/Daraz by 25%, passed on to consumers.

3. Nepal Rastra Bank’s Repo Rate Hikes (Monetary Policy)

   • Idea Used: Contractionary monetary policy to curb inflation.
   • How: In 2023, NRB raised repo rate to 7.5% → commercial banks increased lending rates → borrowing fell by 12% → AD slowed → inflation dropped from 8.5% to 6.5% (by Dec 2023).

## Exam Tip

1. Always define inflation with a measurement method (GDP deflator/CPI) in your answer.

   • ❌ "Inflation is rising prices."
   • ✅ "Inflation is a sustained rise in the general price level of goods and services, typically measured by the GDP deflator or Consumer Price Index (CPI)."

2. Use real Nepal examples to illustrate demand-pull vs. cost-push.

   • Demand-pull: eSewa boom → higher AD → price hikes.
   • Cost-push: NTC fuel hike → higher transport costs → WPI rise.

3. Policy questions require a 2-step answer:

   • Identify the tool (e.g., repo rate hike).
   • Trace the transmission mechanism (e.g., higher repo rate → higher lending rates → lower borrowing → lower AD → lower inflation).

4. For numerical questions:

   • Always show step-by-step calculations (e.g., inflation rate from GDP deflator).
   • Use real data (e.g., Nepal’s 2023 inflation = 8.1%).

5. Diagrams are worth 5–10 marks. Always:

   • Label axes clearly (Price Level, Quantity).
   • Show shifts (dashed lines for AD/AS changes).
   • Mark equilibrium points (P1, P2; Yf).

6. Common mistakes to avoid:

   • Confusing demand-pull (AD shift) with cost-push (AS shift).
   • Ignoring real-world context (e.g., Nepal’s fuel imports, eSewa’s role).
   • Forgetting secondary effects (e.g., wage-price spiral in informal sectors).
