Deregulation is the process of removing or reducing state regulations, typically in the economic sphere. It is the repeal of governmental regulation of the economy. It became common in advanced industrial economies in the 1970s and 1980s, as a result of new trends in economic thinking about the inefficiencies of government regulation, and the risk that regulatory agencies would be controlled by the regulated industry to its benefit, and thereby hurt consumers and the wider economy. Economic regulations were promoted during the Gilded Age, in which progressive reforms were claimed as necessary to limit externalities like corporate abuse, unsafe child labor, monopolization, pollution, and to mitigate boom and bust cycles. Around the late 1970s, such reforms were deemed burdensome on economic growth and many politicians espousing neoliberalism started promoting deregulation.

Neoliberalism, also neo-liberalism, is a term used to signify the late-20th century political reappearance of 19th-century ideas associated with free-market capitalism. The term has multiple, competing definitions, and is often used pejoratively. In scholarly use, the term is frequently undefined or used to characterize a vast variety of phenomena, but is primarily used to describe the transformation of society due to market-based reforms.
