Public funding

A subsidy is a form of financial aid or support extended to an economic sector (or institution, business, or individual) generally with the aim of promoting economic and social policy. Although commonly extended from government, the term subsidy can relate to any type of support – for example from NGOs or as implicit subsidies. Subsidies come in various forms including: direct (cash grants, interest-free loans) and indirect (tax breaks, insurance, low-interest loans, accelerated depreciation, rent rebates).

Furthermore, they can be broad or narrow, legal or illegal, ethical or unethical. The most common forms of subsidies are those to the producer or the consumer. Producer/production subsidies ensure producers are better off by either supplying market price support, direct support, or payments to factors of production. Consumer/consumption subsidies commonly reduce the price of goods and services to the consumer. For example, in the US at one time it was cheaper to buy gasoline than bottled water.

Whether subsidies are positive or negative is typically a normative judgment. As a form of economic intervention, subsidies are inherently contrary to the market's demands. However, they can also be used as tools of political and corporate cronyism.

A production subsidy encourages suppliers to increase the output of a particular product by partially offsetting the production costs or losses. The objective of production subsidies is to expand production of a particular product more so than the market would promote but without raising the final price to consumers. This type of subsidy is predominantly found in developed markets. Other examples of production subsidies include the assistance in the creation of a new firm (Enterprise Investment Scheme), industry (industrial policy) and even the development of certain areas (regional policy). Production subsidies are critically discussed in the literature as they can cause many problems including the additional cost of storing the extra produced products, depressing world market prices, and incentivising producers to over-produce, such as, for example, a farmer overproducing in terms of his land's carrying capacity.

A consumption subsidy is one that subsidises the behavior of consumers. These type of subsidies are most common in developing countries where governments subsidise such things as food, water, electricity and education on the basis that no matter how impoverished, all should be allowed those most basic requirements. For example, some governments offer 'lifeline' rates for electricity, that is, the first increment of electricity each month is subsidised.
