Economics of Market Failure :: Government Intervention

Market mishap has become an increasingly important topic for students. In simple terms, market failure occurs when markets do not bring about frugalal efficiency. There is a clear economic case for government intervention in markets where some pretend of market failure is taking place. Government can justify this by saying that intervention is in the public interest. Government intervention occurs when markets are not working optimally i.e. there is a Pareto sub-optimal allocation of resources in a market/industry. In simple terms, the market may not always assign scarce resources efficiently in a way that achieves the highest total social welfare.There are plenty of reasons why the normal operation of market forces may not lead to economic efficiency.Public GoodsPublic Goods not provided by the free market because of their two main characteristics Non-excludabilitywhere it is not possible to provide a good or service to one person without it thereby being available for othe rs to enjoy Non-rivalrywhere the consumption of a good or service by one person will not prevent others from enjoying itExamples Streetlighting / Lighthouse Protection, Police services, Air defense systems, Roads / motorways, Terrestrial television, Flood defense systems, Public park & beachesBecause of their nature the private sector is unlikely to be willing and able to provide public goods. The government therefore provides them for collective consumption and finances them with general taxation.Merit GoodsMerit Goods are those goods and services that the government feels thatpeople left to themselves will under-consume and which therefore oughtto be subsidized or provided free at the point of use.Both the public and private sector of the economy can provide meritgoods & services. Consumption of merit goods is thought to generatepositive outwardness effects where the social benefit from consumptionexceeds the private benefit.ExamplesHealth services, Education, Work Training, Pu blic Libraries,Citizens Advice, InnoculationsMonopolyFew modern markets meet the stringent conditions required for a perfectly competitive market. The existence of monopoly power is oftenthought to create the potential for market failure and a need forintervention to correct for some of the welfare consequences ofmonopoly power.The classical economic case against monopoly is that Price is higher and output is lower under monopoly than in a competitive market This causes a net economic welfare loss of both consumer and producer surplus Price marginal cost - leading to allocative inefficiency and a pareto sub-optimal equilibrium.
