Definitions

1. Demerit Goods: Goods that are not socially desirable but are over provided by the market.
2. Regulations: Establishment of requirements and standards to regulate behaviour.
3. Negative Externalities: Costs suffered by a third party as a result of an economic transaction, leading to market failure.

Economic Theory

• Market Failure and Demerit Goods:
  • Demerit goods, such as tobacco and alcohol, are overconsumed in a free market due to their negative externalities.
  • State regulations aim to internalize these externalities, reducing consumption to a socially optimal level.
• Types of Regulations:
  • Taxes: Imposing indirect taxes increases the price of demerit goods, reducing quantity demanded (as shown in Diagram 1).
  • Bans and Restrictions: Complete or partial bans can directly reduce consumption.
  • Advertising Restrictions: Limiting advertising reduces consumer demand by decreasing perceived desirability.
  • Minimum Pricing: Setting a floor price to ensure prices remain high, discouraging consumption.

Diagram

• Supply and Demand Diagram:
• 
• Illustrate the imposition of a tax on a demerit good, showing a leftward shift in the supply curve from S to S+tax, leading to a higher equilibrium price from Pe to Pc and lower equilibrium quantity.

Evaluation (SLAP)

• Stakeholders:

  • Consumers: Face higher prices and reduced access, potentially leading to decreased utility.
  • Producers: Experience reduced sales and profits, potentially leading to job losses.
  • Government: Gains tax revenue but may face political backlash.

• Long-run vs. Short-run:

  • Short-run: Immediate reduction in consumption due to higher prices and restrictions.
  • Long-run: Potential for black markets to develop, reducing the effectiveness of regulations.

• Advantages vs. Disadvantages:

  • Advantages: Effective in reducing consumption and generating government revenue. Can lead to improved public health outcomes.
  • Disadvantages: May disproportionately affect low-income consumers. Risk of black markets and reduced government control over quality.

• Prioritize:

  • Effectiveness: Regulations are generally effective in the short term but require continuous monitoring and adaptation to remain effective in the long term.
  • Real-world Example: The UK’s sugar tax led to a 28.8% reduction in sugar content in soft drinks within two years, demonstrating effectiveness in reducing consumption of demerit goods.

Conclusion

• State regulations can effectively reduce the consumption of demerit goods, particularly in the short term.
• Long-term effectiveness requires adaptation to prevent black markets and ensure continued compliance.
• Real-world examples, such as the UK sugar tax, highlight the potential success of such policies when well-implemented.

Definitions

1. Price Floor: A minimum price set by the government for a good, above the equilibrium price.
2. Equilibrium Price: The price at which the quantity demanded by consumers equals the quantity supplied by producers.
3. Surplus: The extra supply that results when quantity supplied is greater than quantity demanded.

Diagram

• A supply and demand graph showing a price floor above the equilibrium price.
  • The equilibrium price (Pe) and quantity (Qe).
  • The price floor line above the equilibrium price (Pfloor).
  • The surplus area between the quantity supplied and quantity demanded at the price floor.

Explanation

• Introduction:
  • Governments impose price floors to achieve specific economic and social objectives.
• Economic Theory:
  • Support for Producers:
    • Price floors are often used to ensure that producers, such as farmers, receive a minimum income. This is particularly relevant in markets where prices are volatile and can fall below the cost of production.
    • Diagram Reference: The price floor ensures that producers receive a price above the equilibrium, leading to higher producer surplus.
  • Protection of Employment:
    • In industries where wages are set as a price floor (minimum wage), the aim is to protect workers from exploitation and ensure a basic standard of living.
    • Diagram Reference: The price floor can lead to a surplus of labor (unemployment) if the minimum wage is set above the equilibrium wage rate.
  • Market Failures:
    • Price floors can be used to correct market failures, such as when the market price does not reflect the true cost of production, including externalities.
    • Diagram Reference: The price floor can help internalize external costs, ensuring that prices reflect the true cost to society.
