This is one of two influential economic theories of how assets are priced in the financial markets. The other is the capital asset pricing model. The arbitrage pricing theory says that the price of a financial asset reflects a few key risk factors, such as the expected rate of interest, and how the price of the asset changes relative to the price of a portfolio of assets. If the price of an asset happens to diverge from what the theory says it should be, arbitrage by investors should bring it back into line.

Buying an asset in one market and simultaneously selling an identical asset in another market at a higher price. Sometimes these will be identical assets in different markets, for instance, shares in a company listed on both the London Stock Exchange and New York Stock Exchange. Often the assets being arbitraged will be identical in a more complicated way, for example, they will be different sorts of financial securities that are each exposed to identical risks. Some kinds of arbitrage are completely risk-free—this is pure arbitrage. For instance, if Euros are available more cheaply in dollars in London than in New York, arbitrageurs (also known as arbs) can make a risk-free profit by buying euros in London and selling an identical amount of them in New York. Opportunities for pure arbitrage have become rare in recent years, partly because of the globalization of financial markets. Today, a lot of so called arbitrage, much of it done by hedge funds, involves assets that have some similarities but are not identical. This is not pure arbitrage and can be far from risk free.

Government policy for dealing with monopoly. Antitrust laws aim to stop abuses of market power by big companies and, sometimes, to prevent corporate mergers and acquisitions that would create or strengthen a monopolist. There have been big differences in antitrust policies both among countries and within the same country over time. This has reflected different ideas about what constitutes a monopoly and, where there is one, what sorts of behavior are abusive. In the United States, monopoly policy has been built on the Sherman Antitrust Act of 1890. This prohibited contracts or conspiracies to restrain trade or, in the words of a later act, to monopolize commerce. In the early 20th century this law was used to reduce the economic power wielded by so-called "robber barons", such as JP Morgan and John D. Rockefeller, who dominated much of American industry through huge trusts that controlled companies' voting shares. Du Pont chemicals, the railroad companies and Rockefeller's Standard Oil, among others, were broken up. In the 1970s the Sherman Act was turned (ultimately without success) against IBM, and in 1982 it secured the break-up of AT&T's nationwide telecoms monopoly. In the 1980s a more laissez-faire approach was adopted, underpinned by economic theories from the Chicago school. These theories said that the only justification for antitrust intervention should be that a lack of competition harmed consumers, and not that a firm had become, in some ill-defined sense, too big. Some monopolistic activities previously targeted by antitrust authorities, such as predatory pricing and exclusive marketing agreements, were much less harmful to consumers than had been thought in the past. They also criticized the traditional method of identifying a monopoly, which was based on looking at what percentage of a market was served by the biggest firm or firms, using a measure known as the Herfindahl-Hirschman index. Instead, they argued that even a market dominated by one firm need not be a matter of antitrust concern, provided it was a contestable market. In the 1990s American antitrust policy became somewhat more interventionist. A high-profile lawsuit was launched against Microsoft in 1998. The giant software company was found guilty of anti-competitive behavior, which was said to slow the pace of innovation. However, fears that the firm would be broken up, signaling a far more interventionalist American antitrust policy, proved misplaced. The firm was not severely punished. In the UK, antitrust policy was long judged according to what policymakers decided was in the public interest. At times this approach was comparatively permissive of mergers and acquisitions; at others it was less so. However, in the mid-1980s the UK followed the American lead in basing antitrust policy on whether changes in competition harmed consumers. Within the rest of the European Union several big countries pursued policies of building up national champions, allowing chosen firms to enjoy some monopoly power at home which could be used to make them more effective competitors abroad. However, during the 1990s the European Commission became increasingly active in antitrust policy, mostly seeking to promote competition within the EU. In 2000, the EU controversially blocked a merger between two American firms, GE and Honeywell; the deal had already been approved by America's antitrust regulators. The controversy highlighted an important issue. As globalization increases, the relevant market for judging whether market power exists or is being abused will increasingly cover far more territory than any one single economy. Indeed, there may be a need to establish a global antitrust watchdog, perhaps under the auspices of the world trade organization.

The colorful name that Keynes gave to one of the essential ingredients of economic prosperity: confidence. According to Keynes, animal spirits are a particular sort of confidence, "naive optimism". He meant this in the sense that, for entrepreneurs in particular, "the thought of ultimate loss which often overtakes pioneers, as experience undoubtedly tells us and them, is put aside as a healthy man puts aside the expectation of death". Where these animal spirits come from is something of a mystery. Certainly, attempts by politicians and others to talk up confidence by making optimistic noises about economic prospects have rarely done much good.

The running down or payment of a loan by installments. An example is a repayment mortgage on a house, which is amortized by making monthly payments that over a pre-agreed period of time cover the value of the loan plus interest. With loans that are not amortized, the borrower pays only interest during the period of the loan and then repays the sum borrowed in full.

It is often alleged that altruism is inconsistent with economic rationality, which assumes that people behave selfishly. Certainly, much economic analysis is concerned with how individuals behave, and homo economicus (economic man) is usually assumed to act in his or her self-interest. However, self-interest does not necessarily mean selfish. Some economic models in the field of behavioral economics assume that self-interested individuals behave altruistically because they get some benefit, or utility, from doing so. For instance, it may make them feel better about themselves, or be a useful insurance policy against social unrest, say. Some economic models go further and relax the traditional assumption of fully rational behavior by simply assuming that people sometimes behave altruistically, even if this may be against their self-interest. Either way, there is much economic literature about charity, international aid, public spending and redistributive taxation.

A British economist (1842–1924), who developed some of the most important concepts in microeconomics. In his best-known work, Principles of Economics, he retained the emphasis on the importance of costs, which was standard in classical economics. But he added to it, helping to create Neo-classical economics, by explaining that the output and price of a product are determined by both supply and demand, and that marginal costs and benefits are crucial. He was the first economist to explain that demand falls as price increases, and that therefore the demand curve slopes downwards from left to right. He was also first with the concept of price elasticity of demand and consumer surplus.

The most famous of all central bank bosses, so far. A former jazz musician turned economist, he became chairman of the board of governors of America's Federal Reserve in 1987, shortly before Wall Street crashed. In 2003, he was reappointed until 2005. He won admirers for delivering monetary policy that helped to bring down inflation and create the conditions for strong economic growth. Some people considered him the nearest thing capitalism had to God. In 1996, he famously wondered aloud whether rising share prices were the result of "irrational exuberance". Economists debate whether history will judge him a failure because he did not prevent the growth of a huge bubble in America's economy.
