Nature of public finance
Public finance is the study of income and expenditure or receipt and payment of government. Public finance refers to how government raises its resources to meet the growing expenditure. Thus, in public finance we study the finances of government. The terms ‘finance’ is money resource i.e. coins. And public is collected name for individual within an administrative territory and finance. Thus public finance in this manner can be said the science of the income and expenditure of the government.
Definition
According to prof. Dalton “public finance is one of those subjects that lie on the border lie between economics and politics. It is concerned with income and expenditure of public authorities and with the mutual adjustment of one another. The principal of public finance are the general principles, which may be laid down with regard to these matters.
According to Adam Smith “public finance is an investigation into the nature and principles of the state revenue and expenditure”
In simple terms, public finance studies the income and expenditure of the government or the public bodies for the welfare of the country.
Nature and scope of public finance
Nature of public finance
Nature of public finance is a science as well as an art.
- Public finance is a science
Science refers to the systematic study of facts. It studies the relationship between facts, various principles, problems and policies relating to revenue and expenditure of the government. It systematically studies the spending and raising of funds by the public authorities. It also explains the best way of collection of taxes and spending them economically.
Arguments in support of public finance as a science
- Public finance studies the relationship between revenue and expenditure of the government
- Scientific methods are used to study public finance
- Public finance is concerned with definite and limited field of human knowledge
- Principles of public finance are empirical
Science is of two types
- It is a positive science as it studies the factual information relating to the problems of government’s revenue and expenditure. In this respect it also offers suggestions
- It is a normative science as it studies the norms of government financial operations. It teaches which taxes to be imposed such as direct or indirect taxes.
2. Public finance as an art
In the words of J.N. Keynes, ”Art is the application of knowledge for achieving definite objectives.” Public finance as an art studies which principles and policies to be adopted in solving the financial problems of the government in best possible way to benefit the society. Fiscal policy is an important instrument to achieve the objective of full employment, economic equality, economic development and price stability, etc.
In sort, public finance is both science and art. It is a positive science as well as normative science.
Scope of public finance
The scopes of public finance are as follows
- Public Revenue
- Public Expenditure
- Public Debt
- Financial Administration
- Public revenue
Public revenue refers to the various sources from which the government collects revenues. Tax is the main sources of government revenue. In other words, public revenue includes income from taxes and receipts from public deposits. Hence all principles of taxation and incidence of taxation are the part of public revenue.
2. Public expenditure
This part studies the principles and problems relating to government expenditure out of the revenue collected from different sources. It also studies the means through which the government keeps the check on its expenditure.
3. Public debt
In this part, we study the problems of raising loans. To meet certain abnormal situations like war, natural calamities, etc government borrows funds from public. The deficit in the budget is met by borrowing the funds. This part studies the borrowing activities of the government.
4. Financial administration
In this part we study how the government controls its financial operations. It includes preparation of budget, audit of accounts, etc
Public finance is the study of policies and principles relating to the income and expenditure of the government. On the other hand, private finance is the study of income and expenditure of the individual. In some cases they are similar but in most of the cases they are different from each other. The below points discussed tells about the difference between public and private finance.
- Objectives - public and private finance have different objectives. Governments are concerned with society welfare and to serve generation after generation. Whereas private individuals are concerned with profits or private consumption.
2. Income expenditure adjustments - Every individual first determine his income and then spend according to his needs. But the government first estimates his expenditure and then determines the income.
3. Nature of borrowing - Government resources are larger than the private individual. Government can raise revenue by national taxes. While individual cannot force others to pay him. At the time of financial crisis government can raise money from its own citizens as well as from foreign markets. But an individual can only borrow funds externally. Government can print money where as individual do not have such right.
4. Printing of new currency - Government can print money where as individual do not have such right. In order to meet obligation during war, flood, etc government can raise money by printing new currency.
5. Nature of budget – The individual prepare family budget according to the income he expects to receive. An individual budget is a surplus budget as he liked to save something for future. But the government prepares the budget of expenditure and then searches ways to fund its expenditures. The government prepares budget annually. Where as an individual does not prepare budget regularly
6. Secrecy of budget – budget of an individual is kept secret and nobody is concerned about an individual personal budget. Whereas the government budget is presented in parliament and widely discussed. All the information is available in news and thus the transparency is maintained.
7. Elasticity of finance – government finance is more elastic then private finance. Government can increase revenue by imposing more taxes. While an individual cannot increase its income suddenly.
8. Coercion to get revenue – government can force those who refuse to pay tax. While an individual do not have such right.
9. Solvency – a state is a long term institution and cannot be declared insolvent. While for an individual, if his liabilities exceeds assets , then he is declared insolvent
10. Provision for the future – government spend large amount on projects which benefits the future generation such as investment in education, health, etc. but for an individual present is more valuable then future.
Financial activities of the state have significant influence on the consumption, production and distribution of the national income of the country.the principle of maximum social advantage governs the financial activities of the government to maximize welfare of the society.
The 'Principle of Maximum Social Advantage' was introduced by British economist Hugh Dalton.
According to Hugh Dalton – the best system of public finance is that which secures the maximum social advantage from its fiscal operations. He stated the following
- Government should collect money and spend it to maximize the welfare of the people.
- When taxes are imposed, dis – utility is created and when expenditure is done, utility is created
- Government must adjust its revenue & expenditure in such a way that the surplus of utility is maximum and dis-utility is minimum.
Assumption of principle of maximum social advantage
- All taxes result in sacrifice and all public expenditure lead to benefit
- Public revenue consist of only taxes and no other sources of income
- The government has only balanced budget, no surplus and deficit budget
- Public expenditure is subject to diminishing marginal social benefit and taxes are subject to increasing marginal social sacrifice.
Hugh Dalton explains the principle of maximum social advantage with reference to
- Marginal social sacrifice
- Marginal social benefit
Marginal social sacrifice (MSS) refers to that amount of social sacrifice undergone by public due to the imposition of an additional unit of tax. Dalton says increase in additional unit of taxation results in additional burden (marginal sacrifice). Total sacrifices increases at an increasing rate.
The above diagram indicates MSS curve rises upwards from left to right. This indicates each additional unit of taxation, result in increase in the level of sacrifice. When unit of taxation is OM1, the marginal social sacrifice id OS1. As the taxation increase from OM1 to OM2, the marginal social sacrifice also increases from OS1 to OS2 and so on.
Marginal social benefits (MSB) refer to the benefit conferred on the society, by an additional unit of public expenditure. The marginal utility of the commodity declines as more units of commodity are made available to the consumers. The social benefit declines as more unit of public expenditure spent. In beginning public expenditure spent on essential activities and later they are spent on less important activities. This result in downward sloping MSB curve from left to right as shown in below figure
The above figure indicates that the social benefit derived out of public expenditure is reducing at a diminishing rate. When the public expenditure was OM1, the marginal social benefit was OB1, and when the public expenditure increase to OM2, the marginal social benefit is reduced at OB2 and so on.
The point of maximum social advantage
Social advantage is maximized at the point where marginal social sacrifice cuts the marginal social benefits curve.
This is at the point P. At this point, the marginal disutility or social sacrifice is equal to the marginal utility or social benefit. Beyond this point, the marginal disutility or social sacrifice will be higher, and the marginal utility or social benefit will be lower.
At point P social advantage is maximum. Now consider point P1, at this point marginal social benefit is P1Q1. This is greater than marginal social sacrifice S1Q1. Since the marginal social sacrifice is lower than marginal social benefit, it makes sense to increase the level of taxation and public expenditure. At point P2 marginal social sacrifice S2Q2 is greater than marginal social benefit P2Q2. Here any increase in taxation and public expenditure bring down the social advantage.
Maximum Social Advantage is achieved at the point where the marginal social benefit of public expenditure is equal to the marginal social sacrifice of taxation, i.e. where MSB = MSS.
This shows that to obtain maximum social advantage, the public expenditure should be carried up to the point where the marginal social benefit of the last rupee spent becomes equal to the marginal social sacrifice of the last unit of rupee taxed.
Limitations
- Difficulties in measuring social benefit
The principle is explained with the help of marginal utility analysis. The marginal utility and disutility are concepts and its objective is difficult to measure. The marginal utility is criticized because it is not possible to measure utility or disutility experienced by people.
2. Unrealistic assumptions
Assumption that every tax is burden to society is unrealistic. For example, taxes on tobacco and alcohol are benefit to society. But tax on education can harm the interest of society. Also, expenditure on health care will rise the interest of society.
3. Neglect non-tax revenue
The principle states that pubic revenue includes only taxation. But in practice public expenditure also financed by other sources like public borrowing, profits from public sector enterprises, etc.
4. Lack of divisibility
The marginal benefit from public expenditure and marginal sacrifice from taxation can be equated only when public expenditure and taxation are divided into smaller units. But this is not possible practically.
5. Large budget size
The government financial operations involve collection of large amount from taxation and spending large amount in public expenditure. The effect of small additional amounts is difficult to measure. Thus it’s difficult to estimate the marginal benefits and the marginal sacrifices.
6. Assumption of static condition
Conditions in an economy continuously changes. It’s not static economy. Some condition can be considered as the point of maximum social advantage but under some certain situation may not be same. For example, in times of war government expenditure and revenue must increase.
