Inflation, Deflation: Causes, Policies & Business Impact

Unit 7 of Macroeconomics for Business explains inflation/deflation mechanics (demand-pull, cost-push, built-in), their real-world costs (menu costs, shoe-leather effects), and how fiscal/monetary policies (open market ops, reserve ratios) can stabilize prices—with Nepalese examples like NTC tariff hikes and NEPSE volat

TAKEAWAYS

  • Inflation ≠ price rise: It’s a sustained increase in the general price level (measured by GDP deflator/CPI), eroding purchasing power (e.g., ₹100 in 2010 buys only ₹30 worth of goods in 2023).
  • Demand-pull vs. cost-push: Demand-pull inflation (excess AD) is cured by contractionary policy (higher interest rates, tax hikes), while cost-push (supply shocks) requires supply-side fixes (subsidies, tech upgrades).
  • Deflation is worse: Falling prices trap firms in debt spirals (e.g., Daraz sellers stuck with unsold inventory) and discourage spending (why buy now if prices will drop?).
  • Monetary policy tools: Central banks (Nepal Rastra Bank) use open market operations, reserve requirement changes, and repo rates to steer inflation—e.g., NRB’s 2022 repo rate hike to 8.5% to curb ₹150→₹200/litre fuel price jumps.
  • Fiscal policy trade-offs: Government spending cuts (e.g., slashing NTC subsidies) reduce inflation but worsen unemployment—businesses must weigh stagflation risks.
  • Global links: Nepal’s inflation is tied to India’s (70% imports), so a ₹10/litre fuel hike in India → ₹5/litre spike in Kathmandu within weeks.

1. Definitions: Inflation, Deflation, and Disinflation

Inflation is not just rising prices—it’s a broad-based increase in the average price level of goods/services over time. Key measures:

  • GDP Deflator:
  • Consumer Price Index (CPI): Basket of 100+ goods (food, fuel, housing) tracked monthly by Nepal’s Central Bureau of Statistics.
  • Producer Price Index (PPI): Measures wholesale price changes (e.g., wheat → flour → bread).

Real-world inflation trends in Nepal vs. Japan

Deflation: Sustained fall in price levels (e.g., Japan’s 1990s "lost decade"). Disinflation: Slower inflation (e.g., Nepal’s CPI dropping from 10% in 2022 to 6% in 2023).

Why it matters: CPI overstates inflation (substitution bias: if rice gets expensive, people buy wheat—but CPI assumes fixed basket). Nepal’s official CPI is underestimated by ~1.5% due to this.


2. Causes of Inflation: The "Too Much Money-Chasing-Few-Goods" Framework

Inflation arises when aggregate demand (AD) outpaces aggregate supply (AS). Three core types:

QuantityPriceOAD (Aggregate Demand)AS (Aggregate Supply)EquilibriumY*P*
Demand-pull inflation: AD shift right of AS

A. Demand-Pull Inflation

Mechanism: Excess aggregate demand (consumption + investment + government spending + net exports) pushes prices up. Causes:

  • Rapid economic growth (e.g., Nepal’s 2022 GDP growth of 5.8% → demand for imports surged).
  • Easy monetary policy (low interest rates → more borrowing → more spending).
  • Government deficits (e.g., NTC’s ₹200 billion subsidy in 2023 → money supply expanded).

Real-World Example: NEPSE Stock Boom (2021–2022)

  • AD surge: Post-pandemic recovery + government stimulus (₹500 billion relief packages) → stock market capitalization doubled in 18 months.
  • Price effect: NEPSE index rose from 1,200 to 2,500 points (208% gain), but inflation hit 9.2% as demand for shares (and underlying goods) outstripped supply.
  • Policy response: NRB hiked repo rate from 5% to 8.5% to cool demand.

B. Cost-Push Inflation

Mechanism: Supply shocks (higher production costs) force firms to raise prices. Causes:

  • Rising input costs: Fuel, electricity, or raw material prices (e.g., global wheat prices up 30% in 2022 → Nepal’s flour mills raised prices by 20%).
  • Wage-price spiral: Workers demand higher wages → firms raise prices → workers demand more → inflation becomes self-sustaining.
  • Natural disasters: 2022 floods in Terai destroyed 40% of rice crops → food inflation hit 12%.

Real-World Example: NTC Tariff Hikes (2023)

  • Supply shock: NTC raised electricity tariffs by 40% to cover losses from free power to industries.
  • Cost passed on: Factories (e.g., garment exporters) raised prices by 15–20% → CPI rose by 1.8% in 3 months.
  • Policy dilemma: NRB could lower interest rates to boost investment, but this risks demand-pull inflation.

C. Built-In (Wage-Price) Inflation

Mechanism: Workers and firms expect inflation and bake it into contracts. How it works:

  1. Workers demand higher wages (e.g., unions push for 15% raises).
  2. Firms raise prices to cover wage costs.
  3. Workers see higher prices → demand even higher wages.
  4. Vicious cycle starts (seen in Nepal’s public-sector jobs where salaries are indexed to CPI).

Example: Civil Service Salary Hikes

  • 2021: Government raised minimum wage by 20% after CPI hit 8%.
  • 2022: Public transport fares rose 15% (cost-push) → private-sector workers demanded raises → inflation expectations rose.

3. Costs of Inflation: Why It’s Bad for Business

Inflation isn’t always "bad"—moderate inflation (2–5%) encourages spending. But high inflation (>10%) hurts:

Cost Type Effect on Business Nepalese Example
Menu Costs Firms must reprint price lists frequently (time/money wasted). Daraz had to update 10M+ product listings in 2022 due to 9% inflation.
Shoe-Leather Costs People spend more time searching for deals (e.g., comparing fuel prices). Kathmandu’s traffic jams worsened as people rushed to fill tanks before price hikes.
Wealth Redistribution Debtors gain, creditors lose (money loses value). Farmers with ₹500M loans in 2020 repaid ₹300M in real terms by 2023.
Uncertainty Businesses hesitate to invest (e.g., new factories). FDI in Nepal dropped 30% in 2022 due to inflation fears.
Tax Distortions Bracket creep: People pay more taxes even if real income stagnates. Salaried employees in ₹500K–₹1M range saw tax bills rise 12% without pay hikes.

4. Deflation: The Silent Killer

Deflation (falling prices) seems good, but it’s worse than inflation for economies:

  • Debt deflation: Loans become more expensive in real terms (e.g., a ₹100 loan must be repaid with ₹150 worth of goods).
  • Consumer delay: Why buy a ₹500,000 car now if it’ll cost ₹400,000 next year?
  • Banking crises: Asset values plummet (e.g., real estate prices fall → banks go bust).

Nepalese Example: 2009 Global Financial Crisis

  • Deflationary pressures: Oil prices fell 40% → Nepal’s import bill dropped → AD collapsed.
  • Impact: Unemployment rose to 45% (informal sector), SMEs closed (e.g., 30% of Kathmandu’s garment shops failed).

5. Policy Responses: How Governments Fight Inflation

Two main tools: Monetary Policy (NRB’s job) and Fiscal Policy (Government’s job).

A. Monetary Policy Tools

Tool How It Works Nepalese Example (2022–2023)
Repo Rate NRB lends to banks at this rate. Higher repo → banks charge more → less borrowing → less spending. NRB hiked repo from 5% to 8.5% → commercial loan rates rose to 12–14% → AD slowed.
Open Market Operations (OMO) NRB buys/sells government securities to control money supply. NRB sold ₹200B in bonds in 2022 to absorb excess liquidity.
Reserve Requirement Banks must hold X% of deposits as reserves. Higher → less lending. NRB raised reserve ratio from 3% to 5% → ₹500B less in circulation.
Credit Ceilings Limits on loan growth for sectors (e.g., real estate). NRB capped housing loans at 15% growth to prevent bubbles.

B. Fiscal Policy Tools

Tool How It Works Nepalese Example
Tax Hikes Less money in people’s pockets → lower spending. VAT increased from 13% to 15% in 2023 → consumer spending dropped 2%.
Government Spending Cuts Reduces AD directly. NTC slashed subsidies by ₹100B → electricity prices rose 30% → inflation eased.
Subsidies Targeted help for essentials (e.g., fuel, food). Government provided ₹500/litre fuel subsidy to poor districts → food inflation slowed.

Trade-off: Fiscal austerity (cuts) reduces inflation but increases unemployment.


6. Special Cases: Stagflation and Hyperinflation

A. Stagflation (Nepal’s 2022 Nightmare)

  • Definition: Stagnant growth + high inflation + high unemployment.
  • Cause: Supply shocks (e.g., global oil crisis) + weak AD.
  • Nepalese Example (2022):
    • GDP growth: 5.8% (slow due to post-pandemic recovery).
    • Inflation: 9.2% (high due to fuel/food shocks).
    • Unemployment: 22% (youth unemployment hit 45%).
  • Solution: Supply-side policies (e.g., invest in agriculture, reduce import tariffs).

B. Hyperinflation (Zimbabwe-Style)

  • Definition: Inflation > 50% per month (e.g., Zimbabwe’s 89.7 sextillion % in 2008).
  • Nepal’s Risk Factors:
    • High fiscal deficit (₹1.5 trillion in 2023).
    • Excess money printing (NRB issued ₹300B in new currency in 2022).
    • Loss of confidence in currency (people hoard dollars).
  • Prevention:
    • Dollarize economy (use USD as backup).
    • Strict monetary controls (e.g., capital controls).

## In the Real World

  1. eSewa & Khalti (Digital Payments)

    • Idea Used: Inflation expectations affect transaction speeds.
    • How? When inflation is high (e.g., 2022), people spend faster to avoid price hikes → eSewa/Khalti saw 40% transaction growth as users rushed to pay bills before prices rose.
    • Business Impact: Merchants on Daraz/Foodmandu offered discounts for digital payments to clear inventory quickly.
  2. NTC Electricity Tariffs

    • Idea Used: Cost-push inflation from subsidy cuts.
    • How? NTC raised tariffs by 40% in 2023 after losing ₹200B/year. Factories (e.g., garment exporters) passed costs to consumers → CPI rose by 1.8% in 3 months.
    • Policy Lesson: Subsidy cuts reduce inflation but hurt SMEs (e.g., Kathmandu’s textile industry shrank by 15%).
  3. NEPSE Stock Market Volatility

    • Idea Used: Demand-pull inflation from speculative bubbles.
    • How? In 2021–2022, low interest rates (5%) + government stimulus led to a 208% NEPSE rally. But when NRB hiked rates to 8.5%, stock prices fell 30% as investors pulled out.
    • Business Impact: Startups struggled to raise capital—only 12 IPOs in 2023 (vs. 45 in 2021).

## Exam Tip

What Examiners Want to See:

  1. Clear distinction between demand-pull (AD shift) and cost-push (AS shift) inflation—always draw AD/AS diagrams.
  2. Real-world examples: Link theory to Nepal’s NTC, NEPSE, or remittance-driven inflation.
  3. Policy trade-offs: If asked about fighting inflation, discuss:
    • Monetary policy (repo rate hikes, OMO) → slows AD but may cause recession.
    • Fiscal policy (tax hikes, subsidy cuts) → reduces inflation but hurts poor.
  4. Numerical questions: For GDP deflator inflation rate: Example: If GDP deflator goes from 525 (2022) to 675 (2023), inflation = 28.57%.
  5. Case study answers: For NTC subsidy cuts, structure your answer as:
    • Cause: Cost-push inflation (higher fuel costs).
    • Effect: Higher electricity prices → CPI rises by X%.
    • Policy response: NRB could hike repo rate, but this may slow economic growth.

Common Mistakes to Avoid:

  • Confusing CPI and GDP deflator: CPI measures consumer prices, GDP deflator measures all goods/services.
  • Ignoring real-world context: Always relate to Nepal’s NTC, NRB, or NEPSE—examiners love this!
  • Overlooking deflation: Many students focus only on inflation—stagflation is a key exam topic.
