LOAN: In general, a transaction in which a legal claim is exchanged for money. The legal claim is typically a contract or promissory note stipulating when and how the money will be repaid. The lender gives up the money and receives the legal claim. The borrower gives up the legal claim and receives the money. A loan can be either an asset or a liability, depending on who does the borrowing and who does the lending. To the borrower, a loan is a liability, something that is owed. The borrower must pay off the loan or repurchase the legal claim. However, to the lender, a loan is an asset, something that is owned. In fact, loans represent a significant part of a bank's assets.

MARKET FAILURES: Imperfections in the exchange process between buyers and sellers that prevent markets from efficiently allocating scarce resources. Market failures come in four varieties -- public goods, market control, externalities, and imperfect information. Market efficiency is achieved if the value of goods produced is equal to the value of foregone production. Markets fail when this efficiency condition is not achieved. Such failures can only be corrected by government intervention. Market failures arise when the voluntary exchange process does achieve the allocative efficiency criterion that the value of goods produced equals the value of goods not produced. The four types of market failures are public goods, market control, externalities, and imperfect information.Public goods causes inefficiency because nonpayers cannot be excluded from consumption, which then prevents voluntary market exchanges. Market control occurs because limited competition among buyers or sellers prevents the equality between demand price and supply price. Externalities prevent efficiency because external costs or benefits mean demand prices or supply prices do not fully reflect the value of goods produced or the value of goods not produced. Imperfect information among buyers or sellers, like externalities, also means that demand prices or supply prices do not fully reflect the value of goods produced or the value of goods not produced. While markets do a relatively good (that is, efficient) job of allocating resources under most circumstances, when they fail, the ONLY alternative is some sort of government intervention. Intervention might take the form of direct government provision or production, often done with public goods. Or intervention might be laws or regulation, a common remedy for market control and imperfect information. Government taxes are another method of intervention that is often recommended for externalities. Market EfficiencyMarket Efficiency | | Before discussing the specific to the failings of markets, first consider perfection in the form of market efficiency. Efficiency in the allocation of resources is achieved when value received is equal to value foregone. With this equality, value cannot be increased by changing the allocation of resources.The exhibit to the right illustrates a typical market. Equilibrium is achieved at a market price of $50 and quantity of 400. In a perfect world, with a perfect market, the demand price fully reflects the value of the good produced and the supply price fully reflects the value of goods not produced. Because demand price is equal to supply price at the equilibrium price of $50, efficiency is also achieved at equilibrium. Unfortunately for markets to achieve efficiency, a few conditions must be achieved: - First: The market must be competitive. Competition among buyers and sellers is what creates equality between demand price and supply price.
- Second: The market must not have any benefits or costs external to the market. The demand price must reflect all value generated from a good and the supply prices must reflect all opportunity cost of foregone production.
- Third: The market buyers and sellers must have complete (ideally, perfect) information about prices and alternatives.
While many markets closely approximate these three conditions, few conform perfectly. Many markets are highly competitive, some have limited competition among either buyers or sellers. Many markets fully reflect the value of goods produced in the demand price and the value of goods not produced in the supply price, some have external benefits and costs. Many markets have relatively good information available to buyers and sellers, some markets have limited information available.Public GoodsPublic goods are goods that can be consumed simultaneously by a large number of people without the consumption by one imposing an opportunity cost on others, what is termed nonrival consumption. They are further characterized by the inability to exclude nonpayers from consumption. Nonrival consumption means that public goods are efficiently allocated if provided at a zero price, something markets are seldom inclined to do. Moreover, the inability to exclude nonpayers gives rise to the free-rider problem, which further inhibits the voluntary exchange of public goods through markets.If markets do attempt the voluntary exchange of public goods, which results in a nonzero market price, then efficiency is not achieved. A nonzero market price means there is no equality between the value of goods produced and the value, or opportunity cost, of goods not produced, which is zero due to nonrival consumption. Common examples of public goods include national defense, public health and environmental quality. In each case consumption by one does not impose an opportunity cost on others and nonpayers cannot be excluded from consumption. And in each case, markets fail to efficiently allocate the production, consumption, or provision. Closely related to public goods are near-public goods and common-property goods that share one but not both of the key characteristics of nonrival consumption or the inability to exclude nonpayers. - Near-public goods, like public goods, are nonrival in consumption, but nonpayers can be excluded. Nonrival consumption means efficiency is achieved if near-public goods are provided at a zero price, which markets don't do.
- Common-property goods, like public goods, are characterized by the inability to exclude nonpayers, but are rival in consumption. Nonrival consumption means efficiency is achieved if markets are used for exchange, but such is not possible with the inability to exclude nonpayers.
Market ControlMarket control arises when buyers or sellers are able to exert influence over the price of a good and/or the quantity exchanged. The ability to control the market, especially the market price, prevents a market from equating demand price and supply price.Market control on the supply side allows sellers to set a demand price, the value of the good produced, above the value of goods not produced. An extreme example of market control on the supply side exists with monopoly, a market with a single seller. A less extreme, but more common example, is oligopoly, a market with a small number of large sellers. Market control on the demand side allows buyers to set a supply price, the value of goods not produced, below the value of the good produced. An extreme example of market control on the demand side exists with monopsony, a market with a single buyer. A less extreme, but more common example, is oligopsony, a market with a small number of large buyers. Common examples of markets with supply-side or demand-side control include city-wide electrical distribution (monopoly), automobile manufacturing (oligopoly), employment in a company town (monopsony), and employment in professional sports (oligopsony). ExternalitiesAn externality exists if a benefit is not included in the demand price or a cost is not included in the supply price. This means that the demand price does not reflect the complete value of the good produced or the supply price does not reflect the complete value of goods not produced. As such, market equilibrium does not achieve an efficient allocation. A noted externality example is pollution. The emission of residuals in the production or consumption of goods impose opportunity costs on others not involved the market exchange. In this case the supply price in the market does not include all opportunity costs of production, the omitted costs are those imposed on others harmed by the pollution. On the benefit side, education provides an example of an externality. The benefits of education extend beyond those receiving the education and thus beyond the market exchange. In this case the demand price in the market does not include the full value of the good production, the omitted value is that received by others benefitting from the education. Imperfection InformationThe lack of information among buyers or sellers often means that the demand price does not reflect all benefits of a good or the supply price does not reflect all opportunity costs of production. That is, buyers might be willing to pay more or less for a good because they don't know the true benefits generated. Or sellers might be willing to accept more or less for a good than the true opportunity cost of production.In many cases, sellers have better information about a good that buyers. Sellers own and control the good, they have direct contact with the good. If there are defects or problems with the good, they are likely to know. Buyers, in contrast, have much less familarity with a good, perhaps only knowing the information provided by the sellers. In this case, buyers are likely to have a different demand price than the value of the good produced, a value based on more complete information. Fixing FailuresShould markets fail for one or more of these reasons, governments are often called into action. The very existence of governments is largely attributable to the market failure of public goods. The scope of modern governments has expanded over the years to address other market failures.Governments have three key tools for addressing the market failures of public goods, market control, externalities, and imperfect information. - Direct Provision: A common method used by governments to address the market failure of public goods is direct provision. That is, governments oversee the production of public goods and/or their distribution to the public. This alternative is most obvious with national defense. The national government hires military personnel, purchases armaments and equipment, maintains military bases, and generally oversees the operations of military actions. Governments are also inclined to directly provide goods failing from market control, so called public utilities that include water distribution, electricity generation, and trash collection.
- Regulation: A second noted method is the regulation of production, consumption, and exchange decisions undertaken by the private sector -- businesses and consumers. That is, governments set the rules of the game, a task they generally undertaken for society, but in this case directed specifically to the correction of market failures. Government regulations are commonly used to address the market failures of market control, externalities, and imperfect information. For example, the price of a firm with significant market control might be regulated by government. Or government might restrict the amount of pollution emissions from a particular productive activity. Regulations requiring sellers to provide information to buyers is a means of addressing the market failure of imperfect information.
- Taxes: A third alternative is to make use of coercive government taxes. That is, governments impose to create disincentives and thus discourage undesirable activities. Taxes are well-suited for controlling externalities or encouraging the provision of information. For example, an industry the creates a pollution externality can be encouraged to efficiency if government imposes a tax equal to the external cost. Alternatively, government subsidies, effectively negative taxes, can be used to encourage activities and address the market failure external benefits.
Government InefficienciesWhile market failures can be corrected, in principle, only through some sort of government action, government intervention does not guarantee a solution nor an efficient allocation of resources. The reason is that governments are also imperfect. Governments have their own set of inefficiencies.A list of government inefficiencies includes: - Voter Apathy: The whole point about efficiency and addressing the scarcity problem is to get the most satisfaction from available resources. When people don't vote, leaders don't know what really satisfies the public.
- Special Interest Groups: In a related matter, when some people don't vote, those who do vote have a greater influence over an election. Leaders seek to provide satisfaction for those special interest groups with the greatest influence. And such groups do not necessarily promote what is best for the entire economy.
- Re-election Minded Politicians: Leaders who only need to please a majority of those who vote can largely ignore the interests of others. Once again, any resulting economic policies are not necessarily in the best interest of the entire economy.
- Complex Bureaucracies: Those who work in the large, complex bureaucracies that tend to make up governments, might not be held responsible for their actions, especially those actions that carry out economic policies. Even the "best" economic policies might not be effectively carried out by government employees.
