Govt intervention in economy

  1. 1. Tools of intervention of Govt. In Market Failure
  2. 2. Government Intervention: Fiscal MeasuresTaxes and Subsidies• The use of taxes and subsidies to correct externalities o Externalities occur when some of the costs or benefits associated with production or consumption of goods and services spill over onto third parties. – the optimum size of a tax
  3. 3. Using taxes to correct a market distortion MC = S Costs and benefits P D O Q1 Quantity
  4. 4. Using taxes to correct a market distortion MSC MC = S Costs and benefits P D External cost O Q2 Q1 Social optimum Quantity
  5. 5. Using taxes to correct a market distortion MSC MC = S Optimum tax = MSC – MC Costs and benefits P D MC O Q2 Q1 Quantity
  6. 6. Government Intervention: Fiscal MeasuresTaxes and Subsidies • The use of taxes and subsidies to correct externalities – the optimum size of a tax – the optimum size of a subsidy
  7. 7. Using subsidies to correct a market distortion MC = S Costs and benefits P D O Q1 Quantity
  8. 8. Using subsidies to correct a market distortion MC = S MSC Costs and benefits External benefit P D O Q1 Q2 Social optimum Quantity
  9. 9. Using subsidies to correct a market distortion MC = S MSC MC Costs and benefits Optimum subsidy = MC – MSC P D O Q1 Q2 Quantity
  10. 10. Government Intervention: Fiscal MeasuresTaxes and Subsidies • The use of taxes and subsidies to correct for monopoly – use of lump-sum taxes • Advantages of taxes and subsidies – Considered the most effective way of solving underconsumption as it is easily implemented – Leaves space for market forces to interact – Provision of revenue for the government • Disadvantages of taxes and subsidies – infeasible to use different tax and subsidy rates – lack of knowledge
  11. 11. Provision of Public Goods A public good is a good/service which is – Non-rivalrous – its benefits are not depleted by an additional user • MC = 0, for allocative efficiency, P = MC = 0 • Public goods have to be provided at no charge – Non-excludable – impossible (or difficult) to exclude people from its benefits • ‘Free rider’ problem arises – no one will pay for what he can get free • Private firms will not provide public goods (unable to charge for consumption) • Public goods, therefore, have to be provided by the government• Examples of public goods include streetlamps and public libraries• Note: a private good is one that is both rivalrous and excludable – automobiles, clothing, food etc.
  12. 12. Provision of Public Goods• Direct provision of goods and services – the provision of public goods – the need to evaluate costs and benefits of publicly provided goods – there is a need to produce merit goods (which are naturally underconsumed) at low prices or for free due to four reasons • Social justice: they should be provided according to need and not ability to pay • Large positive externalities, for example in the provision of free health services helps to contain and combat the spread of disease • Dependants are subject to their guardians decision which are not necessarily the best, therefore the provision of services like free education and dental treatment is needed to protect dependants from uninformed or bad decisions • Ignorance: The problem of imperfect information makes consumers unaware of the positive externalities and benefits that arise from consumption
  13. 13. Nationalization And Expansion of public sector• Nationalization refers to the public (governmental) ownership of certain firms to provide goods or services sold in the market, that is, public corporations engaged in commercial activities. Governments often take over natural monopolies to prevent monopoly pricing and examples include public utilities.• Advantages: – Consumers protected from high prices – Ensuring social costs and benefits are taken into account when production decisions are made• Disadvantages: – No profit motive may lead to nationalized enterprises being allocatively inefficient
  14. 14. Promotion Of competition Effective competition in properly regulated markets can deliver lower prices, better quality goods and services and greater choice for consumers. Competition can create strong incentives for firms to be more efficient and to invest in innovation, thereby helping raise productivity growth. Policy makers should aim to protect and promote competition in markets in order to capture the benefits of markets for consumers and society as a whole. However, markets if not adequately regulated can potentially harm consumers.
  15. 15. Promotion Of competition Drives firms to improve their internal efficiency and reduce costs. Cost minimisation allows firms to deliver the same goods and services to consumers, but at lower prices. This will attract a greater number of consumers and the firm will gain a larger market share. Provides incentives to firms to adopt new technology.• Early adoption of technology and/or new techniques and processes helps firms minimise their costs. Provides incentives to firms to invest in innovation.• Investment in innovation allows firms to improve the quality of their existing products and/or develop new products and services to better suit the changing needs and preferences of consumers. Reduces managerial inefficiency.• Competitive pressures from other firms and new entrants lead firms to look for better, more efficient ways to organise their business. Lack of effective competition could lead firms and managers to operate with inefficient business models and technology as firms are unlikely to lose profits.
  16. 16. Control of price and outputGovernment determines how Market outcomes are to be limited.Output regulation: Government sets quotas or Limits the amount of output that can beprovided by participants in a market. Examples: prohibition of bogus curesPrice regulation: Government sets price controls either as minimum or maximumprices that can be charged in a market. Examples: price controls on drugsstandards regulation: Government sets limits on the characteristics of a product or service Examples: FDA regulations on advertising & quality
  17. 17. More or Less Intervention?• Drawbacks of government intervention – shortages and surpluses – poor information – bureaucracy and inefficiency – lack of market incentives – shifts in government policy – lack of freedom for the individual
