Market Structures

Not all markets are the same. Some have thousands of sellers (Vegetable Market). Some have just one (Indian Railways).

Market Structure determines Pricing Power.

1. Perfect Competition

Characteristics:

• Many sellers, many buyers.
• Identical products (No brand differentiation).
• No barriers to entry.
• No pricing power (Firms are "Price Takers").

Example: Agricultural markets (Wheat, Rice).

• One farmer cannot charge ₹50/kg if market rate is ₹40/kg. Buyers will go elsewhere.

Outcome:

• Low Profit (Due to intense competition).
• Efficient Market (Best allocation of resources).

2. Monopolistic Competition

Characteristics:

• Many sellers, many buyers.
• Differentiated products (Branding matters).
• Some pricing power.
• Low barriers to entry.

Example: Restaurants, Salons, Clothing brands.

• A Starbucks can charge ₹400 for coffee while a local café charges ₹50. Why? Brand differentiation.

Outcome:

• Advertising is crucial.
• Short-term profits (New competitors enter if profitable).

3. Oligopoly

Characteristics:

• Few large sellers dominate.
• High barriers to entry (Capital, Technology).
• Interdependence (Firms watch each other's moves).
• Pricing power (But not absolute).

Example: Telecom (Airtel, Jio, Vi), Aviation (IndiGo, Air India, SpiceJet), Auto (Maruti, Hyundai, Tata).

Behavior:

• Price Wars (Jio's free data disrupted the market).
• Collusion (Illegal, but firms may tacitly "agree" on prices).
• Non-Price Competition (Better network, customer service).

Outcome:

• Moderate Profits.
• Innovation (To differentiate).

Game Theory: The Prisoners' Dilemma

Oligopolies face strategic decisions.

• If Firm A lowers price, Firm B must respond.
• If both lower prices, profits suffer.
• Nash Equilibrium: Both keep prices stable.

4. Monopoly

Characteristics:

• Single seller.
• No close substitutes.
• Complete pricing power ("Price Maker").
• High barriers to entry (Legal, Natural, Technological).

Types:

1. Government Monopoly: Indian Railways, India Post (Pre-2000s).
2. Natural Monopoly: Electricity Distribution (High infrastructure cost).
3. Technological Monopoly: Google Search (Network effects).

Example: Microsoft Windows (1990s).

Outcome:

• High Profits.
• Inefficiency (No competition → Less innovation).
• Deadweight Loss (Prices higher than competitive equilibrium).

Monopoly Regulation

Govts regulate monopolies to prevent exploitation.

• Price Caps: Electricity prices regulated.
• Anti-Trust Laws: Prevent abuse of market power.

7-Day Action Plan

Day 1: List 5 products you buy. Identify their market structure.
Day 2: Read about "Predatory Pricing". How do big firms (Amazon) kill competition?
Day 3: Check the market share of telecom companies in India. Is it an Oligopoly? (Yes).
Day 4: Understand "Barriers to Entry". Why can't you start an airline easily? (Capital, Licenses).
Day 5: Read about Google's antitrust cases. Is it a monopoly in Search?
Day 6: Watch a documentary on "Standard Oil" (John D. Rockefeller). Classic monopoly broken by Govt.
Day 7: Think about your industry. Which market structure does it fit?
