Public service is a service intended to serve all members of a community. It is usually provided by the government to people living within its jurisdiction, either directly (through the public sector) or by financing provision of services. The term is associated with a social consensus (usually expressed through democratic elections) that certain services should be available to all, regardless of income, physical ability or mental acuity. Examples of such services include the fire brigade, police, air force, and paramedics. (See also: Public service broadcasting)
Even where public services are neither publicly provided nor publicly financed, for social and political reasons they are usually subject to regulation going beyond that applying to most economic sectors. Public policy, when made in the public's interest and motivations, can provide public services.
In modern democracies, public service is often performed by employees known as civil servants who are hired by elected officials. Government agencies are not profit-oriented and their employees are motivated very differently. Studies of their work have found contrasting results including both higher levels of effort and fewer hours of work. A survey in the UK found that private sector hiring managers do not credit government experience as much as private sector experience. Public workers tend to make less in wages when adjusting for education, although that difference is reduced when benefits and hours are included. Public workers have other intangible benefits such as increased job security and high wages.
A public service may sometimes have the characteristics of a public good (being non-rivalrous and non-excludable), but most are services which may (according to prevailing social norms) be under-provided by the market. In most cases public services are services, i.e. they do not involve manufacturing of goods. They may be provided by local or national monopolies, especially in sectors which are natural monopolies.
They may involve outputs that are hard to attribute to specific individual effort or hard to measure in terms of key characteristics such as quality. They often require high levels of training and education. They may attract people with a public service ethos who wish to give something to the wider public or community through their work.
Governing bodies have long provided core public services. The tradition of keeping citizens secure through organized military defence dates to at least four thousand years ago.
Maintaining order through local delegated authority originated at least as early as the Warring States period (5th to 3rd centuries BCE) in ancient China with the institution of xian (prefectures) under the control of a centrally-appointed prefect. Historical evidence of state provision of dispute resolution through a legal/justice system goes back at least as far as ancient Egypt.
The widespread provision of public utilities as public services in developed countries usually began in the late nineteenth century, often with the municipal development of gas and water services. Later, governments began to provide other services such as electricity and healthcare. In most developed countries, local or national governments continue to provide such services, the biggest exceptions being the U.S. and the UK, where private provision is arguably proportionally more significant. Nonetheless, such privately provided public services are often strongly regulated, for example (in the US) by Public Utility Commissions.
In developing countries, public services tend to be much less well developed. For example, water services might only be available to the wealthy middle class. For political reasons, the service is often subsidized, which reduces the finance potentially available for expansion to poorer communities. The United Nations Sustainable Development Goal 5 is however, a global initiative which aims to influence the provision of public services and infrastructure to marginalized demographics.
Nationalization took off following the World Wars of the first half of the twentieth century. In parts of Europe, central planning was implemented in the belief that it would make production more efficient. Many public services, especially electricity, fossil fuels and public transport are products of this era. Following the Second World War, many countries also began to implement universal health care and expanded education under the funding and guidance of the state.
There are several ways to privatize public services. A free-market corporation may be established and sold to private investors, relinquishing government control altogether. Thus it becomes a private (not public) service. Another option, used in the Nordic countries, is to establish a corporation, but keep ownership or voting power essentially in the hands of the government. For example, the Finnish state owned 49% of Kemira until 2007, the rest being owned by private investors. A 49% share did not make it a "government enterprise", but it meant that all other investors together would have to oppose the state's opinion in order to overturn the state's decisions in the shareholder's meeting.
A regulated corporation can also acquire permits on the agreement that they fulfill certain public service duties. When a private corporation runs a natural monopoly, then the corporation is typically heavily regulated, to prevent abuse of monopoly power. Lastly, the government can buy the service on the free market. In many countries, medication is provided in this manner: the government reimburses part of the price of the medication. Also, bus traffic, electricity, healthcare and waste management are privatized in this way. One recent innovation, used in the UK increasingly as well as Australia and Canada is public-private partnerships. This involves giving a long lease to private consortia in return for partly funding infrastructure.
As the more advanced social institutions began to take shape they contributed to some counterbalancing of the essential insecurity of man's condition. It was inevitable that ambitious and assertive men should see an opportunity for establishing for themselves positions of power and influence. No doubt many such occasions had their origins in a genuine concern for the public good [...] The position of [...] the war-band leader as the strong arm of the community's defence would increasingly be confirmed by the subjection of the community to the members of what [...] were becoming, demonstrably, elites, [...] This period, embracing part of the fifth and all of the fourth and third millennia before the present era, is absolutely pivotal to the development of the modern world.
Pharaonic Egypt epitomizes a regulatory, public law regime. [...] The principal function of this elaborate apparatus was to maintain order and security, and, above all, to acquire as much of the surplus agricultural wealth and labor as possible.
To ensure the favor of the gods was the preeminent task of ancient rulers worldwide, for they all were priestly kings. The Roman Caesar was the pontifex maximus of Rome's state god. The Chinese emperor certainly stood over his subjects as 'Son of Heaven,' but if he fell into disfavor with heaven and his country was visited by famine, plague, earthquakes, and floods, he could be overthrown. The Moloch of Carthage demanded children as sacrifices; the Aztecs and Mayas offered their Gods still-quivering hearts. These political religions were do ut des religions in which the relationship between deity and worshippers was one of contractual exchange.
