<Li> offsetting market imperfections including internalisation of externalities; </Li> <Li> achievement of social policy objectives including redistribution of income, population control, etc . </Li> <P> Transfers which are straight income supplements need to be distinguished from subsidies . An unconditional transfer to an individual would augment his income and would be distributed over the entire range of his expenditures . A subsidy however refers to a specific good, the relative price of which has been lowered because of the subsidy with a view to changing the consumption / allocation decisions in favour of the subsidised goods . Even when subsidy is hundred percent, i.e. the good is supplied free of cost, it should be distinguished from an income - transfer (of an equivalent amount) which need not be spent exclusively on the subsidised good . </P> <P> Transfers may be preferred to subsidies on the ground that i) any given expenditure of State funds will increase welfare more if it is given as an income - transfer rather than via subsidising the price of some commodities, and ii) transfer payments can be better targeted at a specific income groups as compared to free or subsidised goods . </P>
