Welfare is the provision of a minimal level of well-being and social support for all citizens, sometimes referred to as public aid. In most developed countries welfare is largely provided by the government, and to a lesser extent, charities, informal social groups, religious groups, and inter-governmental organizations.

The welfare state expands on this concept to include services such as universal healthcare and unemployment insurance.

History

In the Roman Empire, the first emperor Augustus provided the 'congiaria' or grain dole for citizens who could not afford to buy food every month. Social welfare was enlarged by the Emperor Trajan. Trajan's program brought acclaim from many, including Pliny the Younger. The Song dynasty government (c.1000AD in China) supported multiple programs which could be classified as social welfare, including the establishment of retirement homes, public clinics, and paupers' graveyards. According to Robert Henry Nelson, "The medieval Roman Catholic Church operated a far-reaching and comprehensive welfare system for the poor..."

Welfare economics is a branch of economics that uses microeconomic techniques to evaluate well-being (welfare) at the aggregate (economy-wide) level. A typical methodology begins with the derivation (or assumption) of a social welfare function, which can then be used to rank economically feasible allocations of resources in terms of the social welfare they entail. Such functions typically include measures of economic efficiency and equity, though more recent attempts to quantify social welfare have included a broader range of measures including economic freedom (as in the capability approach).

The field of welfare economics is associated with two fundamental theorems. The first states that given certain assumptions, competitive markets produce (Pareto) efficient outcomes; it captures the logic of Adam Smith's invisible hand. The second states that given further restrictions, any Pareto efficient outcome can be supported as a competitive market equilibrium. Thus a social planner could use a social welfare function to pick the most equitable efficient outcome, then use lump sum transfers followed by competitive trade to bring it about. Because of welfare economics' close ties to social choice theory, Arrow's impossibility theorem is sometimes listed as a third fundamental theorem.

The Social Welfare, formerly called Social Services, is a functional constituency in the elections for the Legislative Council of Hong Kong first created in 1985. Electors include all the registered social workers.
