1Effectiveness of policies MARKET FAILUREEffectiveness of policiesPolicies to correctReasons for failure5 most importantpointsDeadweight LossMonopolies
2Reasons for Failure• Monopoly Power / Imperfect Competition• Negative Externalities from production and consumption• Positive Externalities from production and consumption• Immobility of Factors of Production (both geographical and occupational)• Market provision of pure Public Goods and quasi Public Goods• Merit Goods and Services and De-Merit Goods• Imperfect and Asymmetric information in markets (leading to information failure)• Missing markets (e.g. absent markets in some environmental resources)Definition of market failureWhen the operation of a market does not lead to economic efficiency
3Monopolies & Market Failure Deadweight LossRemember the following:MC = MR – Maximum Profit or Minimum Loss MC = AR – Allocative Efficiency (Supply = Demand)AC = AR – Breakeven PointAC = MC – Technical Optimum – Productive EfficiencyMCP2P1ARMRQ2Q1

5Government Intervention From the AS course:Maximum Prices - Price Stabilisation - Taxes & Subsidies - Direct Provision.Reasons for intervention:Restore economic efficiency - increase equityFailureConsequenceInterventionMarket PowerP↑Q ↓Competition PolicyMerit GoodsUnderprovidedSubsidy LegislationNegative ExternalitiesOverproducedTaxes LegislationInstabilityPrice fluctuationsBuffer stocksInequalityunequal distributionTaxes Subsidies
6Regulation of monopolies 1. Outlaw formation of Monopolies - Commerce Commission in NZ2. Predatory Pricing - pricing below competition to eliminate competition3. Guaranteed quality of goods and services4. Insist on certain levels of competition in a market
7Redistributing Income & Wealth 1. Social Security benefits and pensions.2. Provision of goods and services3. Taxation - progressive income tax4. Legislation - minimum wage and equal pay legislation5. Training - may improve wages in long term.Equity - Efficiency Trade-OffIntervention in the market by government is to reduce the uneven distribution. Subsidies to lower income groups and taxes on higher income groups maybe regarded as socially desirable but they are interfering with the market and therefore are actually creating inefficiency.BUT - inefficiencies that exist already in the market (externalities monopolies) - intervention may improve efficiency overall.
8Problems of Government intervention 1. Lack of Information2. Difficulty quantifying problems3. Mistiming4. Administration costs5. Political pressure
9Exam Questions4. Large firms necessarily become monopolistic. Monopolies adopt practices that are undesirable. Therefore, large firms should be regulated by governments.Discuss whether there is any truth in this argument.  June 2008Large firms not necessarily monopolisitic - size of market important. Could be a contestable market.Large firm can achieve economies of scale - lower price for consumers.Supernormal profits gives the firm the ability to invest - improve efficiency and R&DMay have to innovate to keep competition out BUT Predatory pricingLarge can drive up price MC=MR to detriment of consumers - not producing at MC=AR but as MC=MR - DWL - graph hereGov’t regulation depends on market power - needs to have correct information about the market.Will intervention improve efficiency???
10Exam Questions2. In 2007 the UK Competition Commission indicated that failure in the market mechanism would result in both winners and losers. (a) Explain why producers are usually the winners and consumers are usually the losers when the market fails. Market clearing D=S perfect information and perfect markets.Imperfect markets and imperfect information market failure occurs.Monopoly influences with resulting higher profits for producers but higher prices for consumers – and with possibly less choice.Externalities which may affect consumers but would not necessarily have to be accounted for by producers. It could be from a lack of information – it is likely that producers will have more information about the effects of a product than consumers.(b) Discuss what the government might do when there are losers because the market mechanism has failed.  June 2010Regulation, taxation, information, controls etc. For and against here
11Exam Questions4 In India the post is delivered partly by private courier firms and partly by the government-owned India Post. The government is keen to increase its share of the market. (a) Explain why a government might wish to increase its control over private firms. Availability of product to all - private sector restricted services - important for the economy - make it more efficient mention productive and allocative - private sector not allocative - supernormal profits being earned - regulate health and safety issues(b) Discuss whether an increase in government control necessarily improves efficiency in an organisation.  Nov 2008Is it already efficient? If firm restricting output and earning large supernormal profit gov’t intervention needed. Increase consumer surplus move towards allocative efficiency - graph here. Gov’t failure also - lack of information - over estimates negative externalities - high tax might reduce firms from investing etc. Political Popularity ?
