Multiplier Effects of Tourism — Keynes, Kahn, Formulas & Real-World Application

By Tourism369 · Tourism Concepts · UGC NET Paper 2 Unit VIII

A tourist checks into a hotel in Jaipur and pays ₹5,000. That single transaction doesn’t just benefit the hotel — it ripples through the entire local economy like a stone dropped in water. This is the tourism multiplier at work. Here is the complete theory behind one of economics’ most powerful concepts.

📖 Origins of the Multiplier Concept

The multiplier concept was first developed by R.K. Kahn in the early 1930s — known as the employment multiplier. It measured how an initial increase in investment creates multiple rounds of employment.

J.M. Keynes then refined the concept into the income or investment multiplier — measuring how an initial increase in investment generates a multiplied increase in national income. Keynes’s version gained worldwide recognition and forms the foundation of modern tourism economics.

In tourism, Mathieson and Wall (1982) defined the tourism multiplier as “a number by which initial tourist expenditure must be multiplied in order to obtain the total cumulative income effect for a specific time period.”

🔢 The Multiplier Formula
Investment Multiplier (Keynes)
K = ΔY / ΔI
Where K = Multiplier · ΔY = Change in Income · ΔI = Change in Investment
Multiplier in Terms of MPC
K = 1 / (1 – MPC) = 1 / MPS
MPC = Marginal Propensity to Consume · MPS = Marginal Propensity to Save
Total Economic Impact of Tourism
Economic Impact = No. of Tourists × Average Spending × Multiplier

Key relationship: The larger the MPC, the greater the multiplier. If MPC = 0.8, K = 1/(1-0.8) = 5. If MPC = 0.5, K = 1/(1-0.5) = 2. This means destinations where people spend a larger proportion of income (rather than saving) have stronger tourism multipliers.

💸 Three Types of Tourism Expenditure
1. Direct Tourism Expenditure
The tourist’s initial spending on hotels, restaurants, transport, shopping, and entertainment. This is the first wave — visible, measurable, and directly attributable to tourism. Creates direct revenue and direct jobs.

Example: Tourist pays ₹5,000 to a Jaipur heritage hotel — this is direct expenditure.

2. Indirect Tourism Expenditure
The transaction between businesses caused by direct tourist spending. The hotel buys vegetables from a local farmer, linen from a textile supplier, spices from a market trader. Each supplier then buys from their own suppliers. This is the “business-to-business” ripple effect.

Example: Hotel buys ₹1,000 worth of food from local farmers — indirect expenditure.

3. Induced Tourism Expenditure
The spending by employees and business owners of tourism enterprises from their wages and profits. The hotel waiter uses his salary to pay school fees, buy groceries, and rent accommodation. Each purchase creates another round of economic activity.

Example: Hotel waiter spends his ₹25,000 monthly salary in the local market — induced expenditure.

📊 Five Types of Tourism Multiplier
1. Sales / Transaction Multiplier
Measures direct + indirect + induced turnover generated by an extra unit of tourist spending. Most commonly used multiplier.
Type I = (Direct + Indirect Sales) / Direct Sales
Type II = (Direct + Indirect + Induced Sales) / Direct Sales
2. Output / Production Multiplier
Measures actual change in production levels — including stock changes at hotels, restaurants, and shops. Focuses on output rather than sales value.
3. Income Multiplier
Measures income generated per unit of tourist spending — including wages, salaries, and profits. Most policy-relevant multiplier for measuring living standard improvements.
Type III Income Multiplier = (Direct + Indirect + Induced Income) / Direct Sales
4. Employment Multiplier
Measures direct + indirect + induced jobs created per unit of tourist spending or per million rupees of tourism revenue. Critical for employment policy analysis.
5. Government Revenue Multiplier
Measures tax revenue generated — both direct taxes on tourism businesses and indirect taxes from the wider economic activity generated by tourism.
🚰 Leakages — What Weakens the Multiplier

Leakages are diversions of money out of the local economy that reduce the multiplier effect. Three main types:

💸 Savings
Money saved rather than spent reduces the circulation of funds through the economy, weakening the multiplier effect.
🏛️ Taxes
Direct and indirect taxes reduce purchasing power, diminishing the indirect and induced rounds of economic activity.
🌍 Imports
Money spent on imported goods (foreign wine, foreign-owned hotel chains, imported food) flows OUT of the local economy — the most damaging leakage for developing tourism destinations.

Key insight: Sustainable, locally-owned tourism has a HIGHER multiplier than mass tourism dominated by international chains — because more money stays in the local economy instead of leaking out through imports and profit repatriation.

🎯 UGC NET Key Points — Module 21
◆ Multiplier first: R.K. Kahn (employment multiplier, 1930s) · Refined by J.M. Keynes (income multiplier)
◆ Mathieson & Wall (1982): Tourism multiplier definition
◆ Formula: K = 1/(1-MPC) = 1/MPS
◆ Larger MPC → Larger multiplier
◆ 3 types of expenditure: Direct + Indirect + Induced
◆ 5 types of multiplier: Sales, Output, Income, Employment, Government Revenue
◆ Type I multiplier = Direct + Indirect only · Type II = Direct + Indirect + Induced
◆ 3 leakages: Savings, Taxes, Imports (imports = most damaging for developing destinations)
◆ Total impact formula: No. of tourists × Average spending × Multiplier
◆ Larger economy = larger multiplier (more diverse supply chains to absorb tourist spending)
