2026

Recap: Lecture 1 ⏪

Key concepts we covered:

📈 Economics studies scarcity and efficiency

🔭 Macroeconomics (big picture) vs. 🔬 Microeconomics (individual decisions)

❓ Three fundamental questions: WHAT, HOW, FOR WHOM

📊 Positive (facts) vs. 💭 Normative (values) economics

👉 Today: How do different economic systems answer these questions?

The Three Fundamental Economic Problems

Every Society Must Solve 🤔

The Three Economic Problems

Every economy, regardless of its system, must answer three fundamental questions about resource allocation.

1. WHAT goods and services to produce?

  • Which products? How much of each?
  • Current consumption vs. future investment?

2. HOW to produce them?

  • Which technologies? Which resources?
  • Labor-intensive vs. capital-intensive?

3. FOR WHOM are goods produced?

  • How to distribute output?
  • Who gets what share of production?

Problem 1: WHAT to Produce? 📦

Tourism Sector Choices

🏨 Hotels & Accommodation

🚌 Transport Infrastructure

🍴 Restaurants & Dining

🏖️ Beach Facilities

🏛️ Museums & Culture

💡 Scarce resources mean choosing between alternatives!

Problem 2: HOW to Produce? ⚙️

Different Production Methods: Hotel Check-in

Traditional Method 👥

  • Human receptionists
  • Paper forms
  • Phone bookings
  • High labor cost
  • Flexible service
  • Personal touch

💰 Cost per check-in: ~€8-12

Automated Method 🤖

  • Self-service kiosks
  • Online booking
  • Mobile check-in
  • High capital cost
  • 24/7 availability
  • Limited flexibility

💰 Cost per check-in: ~€2-4

👉 Decision factors: Initial investment, labor costs, customer preferences, technology reliability

Problem 3: FOR WHOM? 🎯

Who consumes the tourism services produced?

💼 Business Travel

👪 Family Vacations

🏃 Sport Tourism

🌟 Luxury Travel

⛺ Nature Tourism

🧗 Adventure Travel

🧑‍🎓 Educational Tourism

🌴 Beach Holidays

👉 Distribution depends on: Income levels, prices, preferences, government policies

Economic Systems

How Societies Organize Production 🏭

Economic System

The way a society organizes the production and distribution of goods and services to answer the three fundamental questions.

Three fundamental types:

1️⃣ Market Economy (Laissez-faire) - Decisions by individuals and firms

2️⃣ Centrally Planned Economy - Government makes decisions

3️⃣ Mixed Economy (Most common today) - Combination of market and government

Market Economy 📈

Individuals and companies make key production and consumption decisions through markets

Key Features ✅

🏠 Private ownership of resources

🤝 Voluntary exchange in markets

💸 Profit motive drives decisions

⚖️ Price signals coordinate activity

The “Invisible Hand” ✋

  • No central coordinator needed
  • Self-interest → social benefit
  • Competition drives efficiency
  • Markets allocate resources

Adam Smith, “The Wealth of Nations” (1776)

Market Economy: Advantages & Disadvantages

Advantages ✔️

🚀 Efficient allocation - Resources go where most valued

💡 Innovation incentives - Profit rewards new ideas

🛒 Consumer sovereignty - Demand drives production

📈 Flexibility - Quick adaptation to changes

Disadvantages ⚠️

💔 Inequality - Unequal income distribution

🏭 Market failures - Externalities, public goods

💰 Monopoly power - Reduced competition

🌱 Short-term focus - May ignore long-term issues

Centrally Planned Economy 🏦

Government makes key production and consumption decisions

Key Features 📋

🏢 State ownership of resources

💹 Central planning authority

🧾 Government quotas and targets

🛠️ Command system (not prices)

The Central Plan 🗺️

  • Government decides WHAT, HOW, FOR WHOM
  • 5-year plans common
  • Quotas for production
  • Fixed prices

Examples: Soviet Union (historical), Cuba, North Korea

Centrally Planned: Advantages & Disadvantages

Advantages ✔️

⚖️ Equality focus - More equal distribution

🌱 Long-term planning - Can prioritize future

🛡️ Social stability - Basic needs guaranteed

🚀 Rapid mobilization - Can focus resources quickly

Disadvantages ❌

🐌 Inefficiency - Information problems, no market signals

⛔ No innovation - Weak incentives to improve

😞 Consumer dissatisfaction - Limited choice, shortages

📜 Bureaucracy - Slow, rigid decision-making

Centrally Planned Economy Example 🏨

Mixed Economy 🤝

Mixed Economy

Combines elements of both market and centrally planned systems. Most modern economies are mixed, with varying degrees of market freedom and government intervention.

Characteristics:

🏠 Private & public ownership coexist

📈 Markets operate but with government regulation

🛡️ Government provides public goods and services

⚖️ Redistributive policies to address inequality

Mixed Economy: The Balance :scales:

Government’s Role in Mixed Economies

Market Activities 📈

Most goods and services produced privately based on profit motive and consumer demand

Tourism example: Hotels, restaurants, tour operators

Government Activities 🏢

Public goods, regulation, redistribution, addressing market failures

Tourism example: National parks, tourism promotion, safety regulations

👉 The mix varies: USA (more market), Nordic countries (more government), Portugal (balanced)

Production Factors

The Inputs of Production 🏭

Factors of Production

The resources (inputs) used to produce goods and services. All economic systems must decide how to allocate these scarce factors.

Three main factors:

🌿 Land - Natural resources

👥 Labor - Human effort

🏢 Capital - Produced resources

💡 (Some add: Entrepreneurship - organizing & risk-taking)

Land 🏞️

Natural resources and raw materials

Examples 🌍

  • Agricultural land
  • Energy resources (oil, gas)
  • Minerals and metals
  • Forests and water
  • Clean air
  • Climate conditions

In Tourism 🏖️

  • Beaches and coastlines
  • Mountains and landscapes
  • Climate (sun, snow)
  • Natural parks
  • Geographic location

Portugal’s natural assets are key tourism factors!

Labor 👷

Human effort - physical and mental work

Characteristics 💪

  • Physical work
  • Mental work
  • Skills & education (human capital)
  • Time and effort spent
  • Experience and training

In Tourism 🏨

  • Hotel staff and management
  • Tour guides
  • Restaurant workers
  • Airline crew
  • Event organizers

Labor-intensive industry!

Capital 🏗️

Produced resources used to make other goods/services

Types ⚙️

  • Physical capital: Machinery, buildings
  • Infrastructure: Roads, airports
  • Technology: Software, systems
  • Financial capital: Money for investment

Not the same as money - capital produces!

In Tourism ✈️

  • Hotel buildings
  • Airports and airlines
  • Booking systems
  • Restaurant equipment
  • Transport vehicles

High capital requirements!

Comparing Economic Systems 📋

Aspect Market Economy Centrally Planned Mixed Economy
Ownership Private State Both
Coordination Prices/markets Central plan Markets + regulation
Incentives Profit Quotas/orders Profit + public interest
Innovation High Low Medium-High
Efficiency Generally high Often low Variable
Equity Low (unequal) High (equal poverty) Medium
Examples (Pure: rare) Cuba, N. Korea USA, EU, Portugal

Real-World Example: COVID-19 Tourism Response 😷

Different Systems, Different Responses

Market-Led: Portugal 🇵🇹

✅ Private hotels closed voluntarily

💰 Government support (furlough schemes)

📈 Market-driven reopening

💡 Rapid innovation (safety protocols)

🚀 Fast recovery: 31.6M visitors (2024)

Centrally-Planned: Cuba 🇨🇺

🏢 State-owned hotels closed by decree

🚫 No market signals

📜 Political decision to reopen

🐌 Limited innovation

😞 Slower recovery: ~50% of 2019 levels

Exercises 📝

Time for practice!

Let’s test your understanding.

Exercise 1: Multiple Choice

In a market economy, the question “FOR WHOM are goods produced?” is primarily answered by:

A. Government planners deciding who gets what

B. Equal distribution to all citizens

C. Willingness and ability to pay

D. First-come, first-served basis

Answer: C - In market economies, goods go to those willing and able to pay for them. This is how markets allocate resources based on purchasing power.

Exercise 2: Multiple Choice

Which of the following is an example of the CAPITAL factor of production in tourism?

A. A tour guide’s knowledge and skills

B. The beach at Algarve

C. A hotel building in Lisbon

D. The manager’s decision-making ability

Answer: C - The hotel building is capital (produced resource used to provide services). A is labor, B is land, D is labor/entrepreneurship.

Exercise 3: Open Question

Scenario: The Portuguese government is considering two policies for tourism development:

  • Policy A: Let private investors freely build hotels wherever they want
  • Policy B: Government decides where hotels should be built and provides subsidies

Questions:

  1. Identify which economic system each policy represents

  2. List 2 advantages and 2 disadvantages of each policy

  3. Calculate: If a private hotel costs €5M to build and generates €800k annual profit, what’s the payback period?

  4. Recommend which policy Portugal should adopt (justify with economic reasoning)

Exercise 3: Solution (Part a & b)

a) Economic systems:

  • Policy A: Market economy approach
  • Policy B: Centrally planned economy approach

b) Advantages and Disadvantages:

Policy A (Market) Policy B (Planned)
✓ Efficient allocation (demand-driven) ✓ Can correct market failures
✓ Innovation & competition ✓ Ensures regional development
✗ May ignore externalities (overtourism) ✗ Information problems
✗ Unequal regional development ✗ Bureaucratic inefficiency

Exercise 3: Solution (Part c & d)

c) Payback period calculation:

\[\text{Payback Period} = \frac{\text{Initial Investment}}{\text{Annual Profit}} = \frac{€5,000,000}{€800,000} = 6.25 \text{ years}\]

d) Recommendation: Mixed approach (combination)

👉 Use market mechanism (Policy A) as primary driver - private sector is more efficient at identifying demand and driving innovation

👉 Add selective government intervention (Policy B elements) - regional development incentives, environmental regulations, infrastructure investment

💡 This is what Portugal actually does - mostly private sector with strategic government support!
