Regulatory economics

Regulation is generally defined as legislation imposed by a government on individuals and private sector firms in order to regulate and modify economic behaviors. Conflict can occur between public services and commercial procedures (e.g. maximizing profit), the interests of the people using these services (see market failure), and also the interests of those not directly involved in transactions (externalities). Most governments, therefore, have some form of control or regulation to manage these possible conflicts. The ideal goal of economic regulation is to ensure the delivery of a safe and appropriate service, while not discouraging the effective functioning and development of businesses. For example, in most countries, regulation controls the sale and consumption of alcohol and prescription drugs, as well as the food business, provision of personal or residential care, public transport, construction, film and TV, etc. Monopolies, especially those that are difficult to abolish (natural monopoly), are often regulated. The financial sector is also highly regulated. Regulation can have several elements: • Public statutes, standards, or statements of expectations; • A registration or licensing process to approve and permit the operation of a service, usually by a named organization or person; • An inspection process or other form of ensuring standard compliance, including reporting and management of non-compliance with these standards; or • The setting of price controls in the form of price-cap regulation or rate-of-return regulation, especially for natural monopolies. Where there is non-compliance, this can result in: • Financial penalties; or • A de-licensing process through which an organization or person, if judged to be operating unsafely, is ordered to stop or suffer a penalty. Not all types of regulation are government-mandated, so some professional industries and corporations choose to adopt self-regulating models. The probability of regulatory capture is economically biased: vested interests in an industry have the greatest financial stake in regulatory activity and are more likely to be motivated to influence the regulatory body than dispersed individual consumers, each of whom has little particular incentive to try to influence regulators. Regulatory capture is a risk to which an agency is exposed by its very nature. ==Theories of regulation==

The art of regulation has long been studied, particularly in the utilities sector. Two ideas have been formed on regulatory policy: positive theories of regulation and normative theories of regulation. The former examine why regulation occurs. These theories include theories of market power, "interest group theories that describe stakeholders' interests in regulation," and "theories of government opportunism that describe why restrictions on government discretion may be necessary for the sector to provide efficient services for customers." These draw on sociologists (such as Max Weber, Karl Polanyi, Neil Fligstein, and Karl Marx) and the history of government institutions partaking in regulatory processes. "To allow the market mechanism to be sole director of the fate of human beings and their natural environment, indeed, even of the amount and use of purchasing power, would result in the demolition of society." • Information asymmetry deals with transactions in which one party has more information than the other, which creates an imbalance in power that at the worst can cause a kind of market failure. They are most commonly studied in the context of principal-agent problems. Principal-agent theory addresses issues of information asymmetry. Here, the government is the principal, and the operator the agent, regardless of who owns the operator. Principal-agent theory is applied in incentive regulation and multi-part tariffs. == Regulatory metrics ==

The World Bank's Doing Business database collects data from 178 countries on the costs of regulation in certain areas, such as starting a business, employing workers, getting credit, and paying taxes. For example, it takes an average of 19 working days to start a business in the OECD, compared to 60 in Sub-Saharan Africa; the cost as a percentage of GNP (not including bribes) is 8% in the OECD, and 225% in Africa. The Worldwide Governance Indicators project at the World Bank recognizes that regulations have a significant impact in the quality of governance of a country. The Regulatory Quality of a country, defined as "the ability of the government to formulate and implement sound policies and regulations that permit and promote private sector development" is one of the six dimensions of governance that the Worldwide Governance Indicators measure for more than 200 countries. The cost of regulations increased by above 1 trillion and can explain 31-37% of the rise in industry concentration. == Regulatory Quality and Financial Market Integration ==

Measures of regulatory quality, such as the Worldwide Governance Indicators (WGI) Regulatory Quality Index, are widely used in regulatory economics to assess the effectiveness, consistency, and credibility of regulatory frameworks across countries. These indicators capture perceptions of a government's ability to formulate and implement sound policies and regulations that permit and promote private sector development (Kaufmann, Kraay, & Mastruzzi, 2010). In financial economics, regulatory quality has been increasingly examined as a determinant of cross-country financial market integration. Strong regulatory environments are associated with improved investor protection, reduced information asymmetries, and greater confidence in market institutions, all of which facilitate capital flows and co-movement across equity markets (La Porta, Lopez-de-Silanes, Shleifer, & Vishny, 1998; Hail & Leuz, 2006). Recent studies extend this line of inquiry by linking regulatory quality to systemic measures of market integration. For example, Haddad et al. (2026) analyse how variations in regulatory quality influence cross-country equity market co-movements using the Scaled Correlation Index (SCI), a capitalization-weighted aggregation of time-varying correlations across markets (Gupta, Haddad, & Selvanathan, 2024). This approach moves beyond bilateral correlation measures by capturing the extent to which regulatory environments shape a country's embeddedness within the broader global financial system. This emerging literature highlights the role of institutional quality not only in shaping domestic market outcomes but also in conditioning the degree of global financial interconnectedness. ==Deregulation==

In modern American politics Overly complicated regulatory law, increasing inflation, concern over regulatory capture, and outdated transportation regulations made deregulation an appealing idea in the US in the late 1970s. During his presidency (1977-1981), President Jimmy Carter introduced sweeping deregulation reform of the financial system (by the removal of interest rate ceilings) and the transportation industry, allowing the airline industry to operate more freely. President Ronald Reagan took up the mantle of deregulation during his two terms in office (1981-1989) and expanded upon it with the introduction of Reaganomics, which sought to stimulate the economy through income and corporate tax cuts coupled with deregulation and reduced government spending. Though favored by industry, Reagan-era economic policies concerning deregulation are regarded by many economists as having contributed to the Savings and Loan Crisis of the late 1980s and 1990s. The allure of free market capitalism remains present in American politics today, with many economists recognizing the importance of finding balance between the inherent risks associated with investment and the safeguards of regulation. Others support continued regulation on the basis that deregulation of the financial sector led to the 2008 financial crisis and that regulations lend stability to the economy. In 2017, President Donald Trump signed an executive order that he claimed would "knock out two regulations for every new regulation." Trump made the claim: "Every regulation should have to pass a simple test. Does it make life better or safer for American workers or consumers? If the answer is no, we will be getting rid of it." Though largely considered a success and considerably reducing government deficit, critics argue that standards, wages, and employment declined due to privatization. Others point out that lack of careful regulations on some of the privatized industries is a source of continued problems. ==Controversy==

Proponents The regulation of markets is to safeguard society and has been the mainstay of industrialized capitalist economic governance through the twentieth century. Karl Polanyi refers to this process as the 'embedding' of markets in society. Further, contemporary economic sociologists such as Neil Fligstein (in his 2001 Architecture of Markets) argue that markets depend on state regulation for their stability, resulting in a long term co-evolution of the state and markets in capitalist societies in the last two hundred years. Opponents This position is alternatively summarized in what is known as the Iron Law of Regulation, which states that all government regulation eventually leads to a net loss in social welfare. Some argue that companies are incentivized to behave in a socially responsible manner, therefore eliminating the need for external regulation, by their commitment to stakeholders, their interest in preserving reputability, and their goals for long term growth. ==See also==
