Subsidies, by means of creating a wedge between consumer prices and producer costs, lead to changes in demand/ supply decisions. Subsidies are often aimed at : 1. inducing higher consumption/ production 2. offsetting market imperfections including internalisation of externalities; 3. Achievement of social policy objectives including redistribution of income, population control, etc.
Effects of subsidies
Economic effects of subsidies can be broadly grouped into
1.Allocative effects: these relate to the sectoral allocation of resources. Subsidies help draw more resources towards the subsidised sector
2.Redistributive effects: these generally depend upon the elasticities of demands of the relevant groups for the subsidised good as well as the elasticity of supply of the same good and the mode of administering the subsidy.
3.Fiscal effects: subsidies have obvious fiscal effects since a large part of subsidies emanate from the budget. They directly increase fiscal deficits. Subsidies may also indirectly affect the budget adversely by drawing resources away from tax-yielding sectors towards sectors that may have a low tax-revenue potential.
4.Trade effects: a regulated price, which is substantially lower than the market clearing price, may reduce domestic supply and lead to an increase in imports. On the other hand, subsidies to domestic producers may enable them to offer internationally competitive prices, reducing imports or raising exports.
Subsidies may also lead to perverse or unintended economic effects. They would result in inefficient resource allocation if imposed on a competitive market or where market imperfections do not justify a subsidy, by diverting economic resources away from areas where their marginal productivity would be higher. Generalised subsidies waste resources; further, they may have perverse distributional effects endowing greater benefits on the better off people. For example, a price control may lead to lower production
