Mixed Economy Notes

Mixed Economy

15.1 A Mixed Economy

  • Definition: A mixed economic system combines features of both planned and market economies.
  • Ownership: Some firms are privately owned (private sector), while others are government-owned (public sector).
  • Price Determination: Prices are determined by market forces (demand and supply) and government intervention.
  • Influence: Both consumers and the government influence production decisions.
  • Advantages: Aims to leverage the benefits of both market and planned economies while mitigating their drawbacks.
  • Private Sector Benefits: May generate choice, increase efficiency, and create incentives.
  • State Intervention Benefits:
    • Encouraging consumption of beneficial products through subsidies, information, or legislation.
    • Discouraging consumption of harmful products through taxes, information, or legislation.
    • Financing the production of products that cannot be directly charged for (e.g., defense).
    • Promoting a healthy diet.
    • Preventing private sector firms from exploiting consumers via high prices.
    • Maximizing resource use, including labor, to ensure employment.
    • Planning to a greater extent and devoting more resources to capital goods.
    • Helping vulnerable groups and creating a more even income distribution by taxing the rich.
  • Government Consideration: The government should consider all costs and benefits of its decisions.
    • Example: Maintaining a railway line and station by the state if the societal benefit exceeds the cost, even if it's not profitable in the private sector.
  • Risks: Market failure can occur, and government intervention may worsen the situation.

15.2 Maximum and Minimum Prices

  • Price Controls: Governments may limit firms' ability to set prices.
  • Maximum Prices:
    • Purpose: To enable the poor to afford basic necessities.
    • Implementation: Set below the equilibrium price.
    • Consequences: Creates a shortage because quantity demanded exceeds quantity supplied.
    • Solutions: Allocation methods like queuing, rationing, or lotteries to prevent illegal markets.
  • Minimum Prices:
    • Purpose: To encourage production.
    • Implementation: Set above the equilibrium price.
    • Consequences: Creates a surplus because quantity supplied exceeds quantity demanded.
    • Solutions: The government or an official body buys up the surplus to prevent prices from falling.
  • Minimum Wage: A minimum price set on the price of labor.

15.3 Government Measures to Address Market Failure

Subsidies and Indirect Taxes

  • Subsidies:

    • Definition: Extra payment to producers that shifts the supply curve to the right.
    • Impact: Influenced by the size of the subsidy and the price elasticity of demand.
    • Inelastic Demand: Producers pass on most of the subsidy to encourage demand extension; consumers receive most of the benefit.
    • Elastic Demand: Producers keep more of the subsidy; greater impact on quantity sold, less on price.
    • Government Consideration: Opportunity cost of the money used for the subsidy.
      *Figure 15.3: Shows the effect of a subsidy in the case of inelastic demand
      *Figure 15.4: Shows the effect of a subsidy in the case of elastic demand

  • Taxes:

    • Impact: Influenced by the size of the tax and the price elasticity of demand.
    • Inelastic Demand: Greater effect on price than quantity sold.
    • Elastic Demand: Greater effect on quantity sold.
    • Revenue Generation: Tax products with inelastic demand because the quantity sold will not fall by much.
      • Example: A 2taxonaproductwithinitialsalesof2000units/day.Ifsalesfallto1800,therevenueis2 tax on a product with initial sales of 2000 units/day. If sales fall to 1800, the revenue is3600. If demand is elastic and sales fall to 900, the revenue is $$1800.
    • Discouraging Consumption: Tax products with elastic demand (e.g., demerit goods).
      • Example: The problem in using taxation to discourage smoking, as demand for tobacco products is inelastic.
Competition Policy
  • Objective: To promote competitive pressures and prevent firms from abusing their market power.
  • Methods:
    • Preventing mergers that harm consumer interests.
    • Removing barriers to market entry and exit.
    • Regulating monopolies.
    • Prohibiting uncompetitive practices like predatory pricing (charging below cost to drive out rivals) and limit pricing (setting prices low to discourage new entrants).
Environmental Policies
  • Restrictions: Placing limits on pollutants emitted by firms into air, sea, and rivers; fining firms that exceed the limits.
  • Tradable Permits:
    • Mechanism: Issuing permits that allow firms to pollute up to a certain limit. Firms that pollute less can sell part of their allocated limit.
    • Goal: Reduce costs for clean firms and raise costs for polluting firms, leading to a higher market share for cleaner firms and reduced pollution.
Regulation
  • Definition: Rules and laws that place restrictions on firms' activities.
  • Areas of Regulation:
    • Price controls.
    • Uncompetitive behavior.
    • Pollution limits.
    • Target audience for products.
    • Quality of products.
    • Staff management.
  • Examples:
    • Banning the sale of cigarettes to children.
    • Requiring firms to meet certain product standards.
    • Mandating a specified number of regular holidays for workers.
    • Placing restrictions on shop opening/closing times.
    • Controlling bus routes.
  • Advantages: Regulations are backed by law and are easily understood.
  • Disadvantages:
    • Enforcement can be difficult and expensive.
    • Regulations work only if most people agree with them.
    • Regulations may not directly compensate those who suffer from market failure.
    • Regulations may be too restrictive, reducing market flexibility and creating barriers to entry.
Nationalization and Privatization
  • Nationalization: Moving the ownership and control of an industry from the private sector to the government.
    • Government-owned entities: State-owned enterprises, public corporations, and nationalized industries.
    • Management: Chairman and board of managers appointed by the government, accountable to the government.
    • Funding: From the government, government-approved loans, and the private sector.
    • Aim: Primarily to work in the public interest, not always to make a profit.
    • Advantages:
      • Decisions based on full costs and benefits.
      • Influence economic activity.
      • Prevent abuse of market power.
      • Easier planning and coordination.
      • Ensure basic industries survive, charge low prices and produce good quality.
    • Disadvantages:
      • Difficult to manage and control.
      • Inefficiency, low-quality products, and high prices due to lack of competition.
      • Reliance on subsidies, with opportunity costs for tax revenue.
      • Slow decision-making.
  • Privatization: Selling state-owned enterprises to the private sector.
    • Arguments for Privatization:
      • Private sector firms produce products desired by consumers at low cost and offer them at low prices.
      • Market forces provide an incentive for firms to be efficient.
      • Greater choice.
      • Reduced administration costs.
      • Quicker response to changing conditions.
      • Less risk of under-investment.
    • Criticisms of Privatization:
      • Private sector firms may not face full market pressure and may become monopolies.
      • They may not consider the total costs and benefits to society.
      • Reduces government control of the economy.
Direct Provision
  • Essential Services: Governments provide affordable housing to rent, education, and healthcare.
    • These are seen as essential services and some governments produce them at not cost or subsidised costs.
  • Merit Goods: Education and healthcare are merit goods.
    • Definition: A good whose benefit to consumers and others is undervalued by them.
    • Government Role: Governments produce educational and healthcare services and other merit goods (e.g., library services) and consume them.
    • To stimulate the consumption of merit goods, governments also pay private sector firms to produce them, provide information about their benefits and make their consumption compulsory.
Public Goods
  • Characteristics:
    • Non-excludable: Cannot exclude someone from enjoying the benefits even if they don't pay.
    • Non-rival: One person's consumption does not reduce another's enjoyment.
  • Examples: Street lighting, sea defenses.
  • Government Role: Governments produce or finance public goods through taxation.
Unfairness
  • Equity: Governments intervene to address unfairness in income distribution.
  • Basic Necessities: Governments try to ensure everyone has access to housing, education, and healthcare.
  • Methods: Financial assistance to the poor, free essential products, and taxation to reduce income and wealth inequality.
  • Reasons for Intervention:
    • Uneven income distribution can be socially divisive.
    • The elderly and sick may be unable to earn incomes.
    • Poverty can lead to poorer health, education, and productivity.
Effectiveness of Government Intervention
  • Risk of Government Failure: May overestimate benefits of merit goods or find it difficult to calculate the efficient quantity of public goods.
  • Political Influence: Decisions may be influenced by political factors and corruption.
  • Reduced Economic Efficiency: High taxes and unemployment benefits may reduce incentives to work.
Development of Effectiveness of Government Intervention
  • Debate: Whether public or private sector expenditure leads to a more efficient allocation of resources.
  • Considerations:
    • Private sector: Profit incentive may lead to high-quality, low-cost projects, but monopolies may charge high prices.
    • Public sector: May not keep costs down due to lack of commercial expertise; decision-making delays.
  • Cost-Benefit Analysis (CBA): A method of assessing investment projects, that takes into account social costs and benefits.
    • Private Costs: Land, labor, building materials, and maintenance.
    • Private Benefits: Revenue earned.
    • External Costs: Environmental damage, noise, risk of accidents, and traffic congestion.
    • External Benefits: Employment, tourism, and attractiveness as a site for domestic firms and multinational companies (MNCs).
    • Decision Rule: If social benefits exceed social costs, the project may proceed if the net social benefit is greater than that on rival projects.
    • Opportunity Cost: Government expenditure on one item always involves a significant opportunity cost.
