Introduction to Economics

Externalities and Property Rights

  • Sections Covered: 14.2, 14.4, and 14.5

  • Importance of understanding the relationship between externalities and property rights in economics.

Private Solutions to Externalities

Basic Concepts

  • Price-Quantity Graph Analysis:

    • Marginal Social Benefit (MSB)

    • Marginal Private Cost (MPC)

    • Marginal Social Cost (MSC)

    • Marginal Private Benefit (MPB)

  • Example Scenario: Roommate smoking

    • Analysis takes into account the absence of government intervention.

Private Solutions

  • Roommate's Incentive Structure

    • Without taxes or regulation, the roommate has limited motivation to limit smoking.

Scenario Analysis

Scenario 1

  • Roommate's benefit from smoking: €500

  • Your cost from smoking: €800

    • Suggested Action: Pay roommate to not smoke (1)

Scenario 2

  • Roommate's benefit from smoking: €1000

  • Your cost from smoking: €800

    • Suggested Action: Pay roommate to not smoke (2)

Coase Theorem

  • Ronald Coase (Nobel Prize, 1991)

    • Key Concept: When individuals can negotiate without cost, they can achieve efficient solutions to problems stemming from externalities.

Efficiency of Property Rights

  • Definition of Inefficiency:

    • A situation where it is possible to make someone better off without harming others.

  • Efficiency depending on property rights:

    • If the roommate holds property rights, compensating them is efficient.

    • If you hold property rights, receiving compensation for smoking cessation is efficient.

Importance of Property Rights

  • Allocation of property rights plays a crucial role in decision-making.

    • Key Questions:

      • Who has the right to smoke?

      • Who maintains the right to clean air?

Example Case: Mr. Burns and Bart

  • Scenario Overview:

    • Mr. Burns owns a textile factory; Bart is a fisherman affected by pollution.

  • Outcomes:

    • With Filter: Mr. Burns gains €100/day; Bart gains €100/day.

    • Without Filter: Mr. Burns gains €130/day; Bart gains €50/day.

Transactions Analysis

  1. When Mr. Burns has property rights and transactions are costly:

    • Economic efficiency considerations.

  2. When Mr. Burns has property rights and transactions are costless:

    • Direct negotiations would yield optimal solutions.

  3. When Bart has property rights and transactions are costly:

    • Different dynamics unfold with varying efficiency.

  4. When Bart has property rights and transactions are costless:

    • Potential for mutual benefit outcomes.

Externalities and Efficiency

  • Identify Qsoc (socially optimal quantity) versus individual production quantities.

  • Importance of defining deadweight loss under scenarios of pollution and inefficiency.

Lack of Property Rights Consequences

  • Problems arising from the absence of property rights:

    • Examples: Overexploitation of ocean fish and wildlife.

  • Tragedy of the Commons:

    • Resources exploited until marginal benefits reach zero; opportunity costs ignored.

Case Study: Atlantic Salmon Stocks

Analysis

  • EU Common Fisheries Policy reducing salmon stock levels.

Addressing the Tragedy of the Commons

  • Current Solutions:

    • Strict fishing quotas in the EU.

    • Handling ivory poaching by balancing private ownership and public regulations.

Contemplating Impractical Private Ownership

Difficult Scenarios

  • Timber resources, whales in international waters, and multinational pollution challenges.

Lecture Expectations

  • Comprehend property rights and transaction costs.

  • Evaluate feasibility of private solutions to reduce external costs.

  • Understand the tragedy of the commons concepts.
