Conditions Regarding the Private Market Efficiency
If private markets can provide efficient results and if the distribution of income is socially acceptable, then there is no possibility or existence of public service. In many cases, however, conditions for private market efficiency is violated. For example, if many people can enjoy the same good at the same time (non-rival, non-exclusive consumption), then the private market may provide too little of the commodity. national defense is an example of non-rival consumption, or public goods.
In theory, under certain circumstances, private markets to allocate goods and services between individuals efficiently (in the sense that produces waste that individual tastes are consistent with the productive capacity of the economy). “Market Failure” occurs when private markets to allocate goods and services efficiently. The existence of market failure to provide justification based on efficiency for the collective or state provision of goods and services. Causes such as externalities, public goods, benefit information, strong economies of scale and network effects can cause market failure. Publicly available through government or voluntary associations, however, there are other inefficiencies, termed “government failure.”
In general assumption, the government’s decision on the scope and level of efficiency of their activities can be effectively separated from decisions about the design of the tax system (the separation of black bird). In this view, public sector programs should be designed to maximize social benefits minus costs (cost-benefit analysis), then the income needed to pay the fees to be raised through the tax system that creates the smallest amount possible yield losses to private. In practice, the government budget or the community is much more complicated and often leads to practices that are inefficient.
The Government may pay the cost of borrowing (eg, bonds), although loan is a method of distribution of tax burden over time rather than a replacement tax. deficit is the difference between public expenditure and revenue. The accumulated deficit from time to time is the total public debt.
Deficit financing allows the government to ease the tax burden from time to time, and give the government an important tool for fiscal policy. The deficit also could limit the government’s choice of successor. public finances is closely related to the problem of income distribution and social equality. The government can redistribute income through transfer or design of tax systems that treat a high income and low income households are different.
