Introduction ↓
The 'Principle of Maximum Social Advantage' was introduced past times British economist Hugh Dalton.
According to Hugh Dalton, "Public Finance" is concerned alongside income & expenditure of world authorities too alongside the adjustment of 1 alongside the other.

Budgetary activities of the authorities results inwards transfer of purchasing ability from but about individuals to others. Taxation causes transfer of purchasing ability from taxation payers to earth authorities, spell world expenditure results inwards transfers dorsum from earth authorities to but about individuals, hence fiscal operations of the authorities travail 'Sacrifice or Disutility' on 1 mitt too 'Benefits or Utility' on the other.
This results inwards changes inwards designing of production, consumption & distribution of income too wealth. So it is of import to know whether those changes are socially advantageous or not.
If they are socially advantageous, too then the fiscal operations are justified otherwise not.
According to Hugh Dalton, "The best arrangement of world finance is that which secures the maximum social wages from the operations which it conducts."
Principle of Maximum Social Advantage (MSA) ↓
The 'Principle of Maximum Social Advantage (MSA)' is the primal regulation of Public Finance.
The Principle of Maximum Social Advantage states that world finance leads to economical welfare when pubic expenditure & taxation are carried out upwards to that dot where the benefits derived from the MU (Marginal Utility) of expenditure is equal to (=) the Marginal Disutility or the sacrifice imposed past times taxation.

Hugh Dalton explains the regulation of maximum social wages alongside reference to :-
- Marginal Social Sacrifice
- Marginal Social Benefits
This regulation is yet based on the next assumptions :-
- All taxes outcome inwards sacrifice too all world expenditures Pb to benefits.
- Public revenue consist of alone taxes too no other sources of income to the government.
- The authorities has no surplus or deficit budget but alone balanced budget.
- Public expenditure is dependent area to diminishing marginal social practise goodness too taxes are dependent area to increasing marginal social sacrifice.
Marginal Social Sacrifice (MSS) ↓
Marginal Social Sacrifice (MSS) refers to that amount of social sacrifice undergone past times world due to the imposition of an additional unit of measurement of tax.
Every unit of measurement of taxation imposed past times the authorities taxes outcome inwards loss of utility. Dalton says that the additional burden (marginal sacrifice) resulting from additional units of taxation goes on increasing i.e. the full social sacrifice increases at an increasing rate. This is because, when taxes are imposed, the stock of coin alongside the community diminishes. As a outcome of diminishing stock of money, the marginal utility of coin goes on increasing. Eventually every additional unit of measurement of taxation creates greater amount of affect too greater amount of sacrifice on the society. That is why the marginal social sacrifice goes on increasing.
The Marginal social sacrifice is illustrated inwards the next diagram :-
The to a higher house diagram indicates that the Marginal Social Sacrifice (MSS) bend rises upwards from left to right. This indicates that alongside each additional unit of measurement of taxation, the marking of sacrifice likewise increases. When the unit of measurement of taxation was OM1, the marginal social sacrifice was OS1, too alongside the increment inwards taxation at OM2, the marginal social sacrifice rises to OS2.
Marginal Social Benefit (MSB) ↓
While imposition of taxation puts burden on the people, world expenditure confers benefits. The practise goodness conferred on the society, past times an additional unit of measurement of world expenditure is known every bit Marginal Social Benefit (MSB).
Just every bit the marginal utility from a commodity to a consumer declines every bit to a greater extent than too to a greater extent than units of the commodity are made available to him, the social practise goodness from each additional unit of measurement of world expenditure declines every bit to a greater extent than too to a greater extent than units of world expenditure are spent. In the beginning, the units of world expenditure are spent on the virtually essential social activities. Subsequent doses of world expenditure are spent on less too less of import social activities. As a result, the bend of marginal social benefits slopes downward from left to correct every bit shown inwards figure below.
In the to a higher house diagram, the marginal social practise goodness (MSB) bend slopes downward from left to right. This indicates that the social practise goodness derived out of world expenditure is reducing at a diminishing rate. When earth expenditure was OM1, the marginal social practise goodness was OB1, too when earth expenditure is OM2, the marginal social practise goodness is reduced at OB2.
The Point of Maximum Social Advantage ↓
Social wages is maximised at the dot where marginal social sacrifice cuts the marginal social benefits curve.
This is at the dot 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 volition live on higher, too the marginal utility or social practise goodness volition live on lower.
At dot P social wages is maximum. Now see Point P1. At this dot marginal social practise goodness is P1Q1. This is greater than marginal social sacrifice S1Q1. Since the marginal social sacrifice is lower than the marginal social benefit, it makes to a greater extent than feel to increment the marking of taxation too world expenditure. This is due to the argue that additional unit of measurement of revenue raised too spent past times the authorities leads to increment inwards the cyberspace social advantage. This province of affairs of increasing taxation too world expenditure continues, every bit long every bit the levels of taxation too expenditure are towards the left of the dot P.
At dot P, the marking of taxation too world expenditure moves upwards to OQ. At this point, the marginal utility or social practise goodness becomes equal to marginal disutility or social sacrifice. Therefore at this point, the maximum social wages is achieved.
At dot P2, the marginal social sacrifice S2Q2 is greater than marginal social practise goodness P2Q2. Therefore, beyond the dot P, whatever farther increment inwards the marking of taxation too world expenditure may select downwards the social advantage. This is because; each subsequent unit of measurement of additional taxation volition increment the marginal disutility or social sacrifice, which volition live on to a greater extent than than marginal utility or social benefit. This shows that maximum social wages is attained alone at dot P & this is the dot where marginal social practise goodness of world expenditure is equal to the marginal social sacrifice of taxation.
Conclusion ↓
Maximum Social Advantage is achieved at the dot where the marginal social practise goodness of world expenditure too the marginal social sacrifice of taxation are equated, i.e. where MSB = MSS.
This shows that to obtain maximum social advantage, earth expenditure should live on carried upwards to the dot where the marginal social practise goodness of the concluding rupee or dollar spent becomes equal to the marginal social sacrifice of the concluding unit of measurement of rupee or dollar taxed.
