Market Failure | ||
In microeconomics, the term "market failure" does not mean that a given market has ceased functioning. Instead, a market failure is a situation in which a given market does not efficiently organize production or allocate goods and services to consumers. Economists normally apply the term to situations where the inefficiency is particularly dramatic, or when it is suggested that non-market institutions would provide a more desirable result. On the other hand, in a political context, stakeholders may use the term market failure to refer to situations where market forces do not serve the "public interest," a subjective assessment that is often made on social or moral grounds. The four main types or causes of market failure are...* Monopolies or other cases of abuse of market power where a “single buyer or seller can exert significant influence over prices or output”). Abuse of market power can be reduced by using antitrust regulations. * Externalities, which occur in cases where the “market does not take into account the impact of an economic activity on outsiders.” There are positive externalities and negative externalities.[9] Positive externalities occur in cases such as when a television program on family health improves the public’s health. Negative externalities occur in cases when a company’s processes pollutes air or waterways. Negative externalities can be reduced by using government regulations, taxes, or subsidies, or by using property rights to force companies and individuals to take the impacts of their economic activity into account. * Public goods such as national defence [10]and public health initiatives such as draining mosquito-breeding marshes. For example, if draining mosquito-breeding marshes was left to the private market, far fewer marshes would probably be drained. To provide a good supply of public goods, nations typically use taxes that compel all residents to pay for these public goods (due to scarce knowledge of the positive externalities to third parties/social welfare); and * Cases where there is asymmetric information or uncertainty (information inefficiency). [11]. Information asymmetry occurs when one party to a transaction has more or better information than the other party. Typically it is the seller that knows more about the product than the buyer, but this is not always the case. Sellers in some markets have better information than the buyer. For example, used-car salespeople may know how whether a used car has been used as a delivery vehicle or taxi, information that may not be available to buyers. An example of a situation where the buyer may have better information than the seller would be an estate sale of a house, as required by a last will and testament. A real estate broker purchasing this house may have more information about the house than the family members of the deceased. This situation was first described by Kenneth J. Arrow in a seminal article on health care in 1963 entitled "Uncertainty and the Welfare Economics of Medical Care," in the American Economic Review. George Akerlof later used the term asymmetric information in his 1970 work The Market for Lemons. Akerlof noticed that, in such a market, the average value of the commodity tends to go down, even for those of perfectly good quality, because the buyer has no way of knowing whether the product they are buying will turn out to be a "lemon" (a defective product).
