Regulatory economics is the economics of regulation, in the sense of the application of law by government that is used for various purposes, such as centrally-planning an economy, remedying market failure, enriching well-connected firms, or benefiting politicians (see capture). It is not considered to include voluntary regulation that may be accomplished in the private sphere.
For example, the sale and consumption of alcohol and prescription drugs are controlled by regulation in most countries, as are the food business, provision of personal or residential care, public transport, construction, film and TV, etc. Monopolies are often regulated, especially those which are difficult to abolish (natural monopoly). The financial sector is also highly regulated.
Regulation can have several elements:
This differs profoundly from regulation in any voluntary sphere of activity. For example, when a broker purchases a seat on the New York Stock Exchange, there are explicit rules of conduct to which the broker must conform as contractual and agreed-upon conditions governing participation. Contrast this with the coercive regulations of the U.S. Securities and Exchange Commission, which are imposed without regard for any individual's consent or dissent. Other examples of voluntary compliance in structured settings include the activities of Major League Baseball, FIFA (the international governing body for professional soccer), and the Royal Yachting Association (the UK's recognised national association for sailing). Regulation in this sense approaches the ideal of an accepted standard of ethics for a given activity, to promote the best interests of the people participating as well as the acceptable continuation of the activitiy itself within specified limits.
In the United States, throughout the 18th and 19th centuries, the government engaged in substantial regulation of the economy. For example, in the 18th century, with mercantilism production and distribution of goods were regulated by government ministries. Subsidies were granted to agriculture and tarrifs were imposed. This type of intervention continued throughout the 19th century. From the time of the administration of President Franklin D. Roosevelt until the late 1970s, the regulation of infrastructure was considered necessary from the standpoint of national security: whether in war or peace, a nation without adequate and reliable transport, telecommunications, public health, banking, and public utilities was considered insecure, and the government assumed the responsibility to ensure that this infrastructure was adequate. It was considered imprudent to give this responsibility over to private hands. In 1946, the U.S. Congress enacted the Administrative Procedure Act, which established some means to oversee the expansion of federal regulation. The APA established uniform procedures for a federal agency's promulgation of regulations, and adjudication of claims. The APA also sets forth the process for judicial review of agency action.
During the late 1970s and 1980s, regulation was seen as imposing unnecessary 'red tape' and other restrictions on businesses. This in turn was interpreted as hurting economic efficiency. Further, regulatory agencies were often seen as having been captured by the regulated industries and so not serving the public interest. As a result, there has been a movement towards deregulation in recent years.
One example is the international monetary system: it is now much easier to transfer capital between countries. As a result, the globalisation of markets has increased.
Privatisation of industries which had been under previous government control was a wide form of deregulation in Britain throughout the later years of the last century. Some argue that although this has increased choice in services, their standards have declined and wages and employment have been reduced.
Some, particularly libertarians, feel that there has been little progress on deregulation, and that controls on small businesses are greater than ever. They feel that deregulation is an aspirational rather than a real intention. Others, usually those on the Left, have argued that deregulation has gone too far, and given too much power to corporations and special interests, while removing the power of the people's elected representatives. Therefore they support a process of re-regulation.
Many criticize the influence of Intellectual Property Rights and other sorts of national regulations on the internet and IT business (software patents, DRM, trusted computing).
The Austrian School economists, beginning with Ludwig von Mises, see regulations as problematic not only because they disrupt market processes, but also because they tend only to bring about more regulations. According to Austrian theory, every regulation has some consequences besides those originally intended when the regulation was implemented. If the unintended consequences are undesirable to those with the power to regulate, there exist two alternative possibilities: do away with the existing regulation, or keep the existing regulation and institute a new one as well to treat the unintended consequence of the old one. In practice, regulators very seldom even consider that the problems they detect may actually be the consequence of prior regulation, so the second option is preferred far more often than the first. The new regulation, however, has unintended consequences of its own which bring about this cycle anew. If unchecked, the result over time is regulation so extensive as to amount to a state run economy.
Laissez-faire advocates do not oppose monopolies unless they maintain their existence through coercion to prevent competition (see coercive monopoly), and often assert that monopolies have historically developed only because of government intervention rather than due to a lack of intervention. Specifically, every regulation has some associated cost of compliance. If these costs increase the total cost of operation enough to make new entry into a market prohibitive but allow existing firms to continue to generate a profit, the regulation effectively cartellizes or monopolizes the industry. When existing firms are able to lobby for regulation, this effectively becomes an opportunity to do away with competitive rivals.
Most economists argue that minimum wage laws cause unnecessary unemployment, for the same reason that a minimum price on anything will decrease the quantity of it that people purchase. If a minimum wage law is passed that makes it illegal to pay less than M per hour, employers will continue to keep on payroll only those workers whose hourly work brings in more than M in revenues. Consequently, those workers who are least productive, and therefore are likely to be paid the least before a minimum wage, are also the ones most likely to become unemployed after a minimum wage is implemented.
Another argument against regulation is that laws against insider trading reduce market efficiency and transparency. If a firm is "cooking the books," insiders, without restraint on insider trading, will take short positions and lower the share price to a level that aggregates both insider and outsider knowledge. If insiders are restrained from using their knowledge to make transactions, the share price will not reflect their insider information. If outsider investors (those whom such laws are supposed to protect) buy shares, their purchase price won't reflect the insider knowledge and will be high by comparison to the price after the insider information becomes public. The outsider wind up taking an avoidable loss. If insiders were allowed to trade freely, the price would never get as high to begin with, and outsiders would lose less money.
Another position held by most economists is that government-enforced price-ceilings cause shortages. If the public is willing to buy Q units of some good at price P, and the sellers of that good are willing to sell Q units at P, then in the absence of regulation, the market for that good will clear. That is, everyone who wants to buy or sell at price P will be able to do so. If a regulation imposes a price ceiling below P, sellers will be willing to sell some lesser quantity, Q - a, and buyers will be willing to buy some greater quantity, Q + b, at the new price. In addition to a shortage of a + b units, there is also the matter of deciding who should get the units offered, since at the regulation price, demand will exceed supply.
