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

Budgetary activities of the authorities results inwards transfer of purchasing ability from 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 about individuals, thus fiscal operations of the authorities crusade 'Sacrifice or Disutility' on 1 mitt together with 'Benefits or Utility' on the other.
This results inwards changes inwards blueprint of production, consumption & distribution of income together with wealth. So it is of import to know whether those changes are socially advantageous or not.
If they are socially advantageous, together with so the fiscal operations are justified otherwise not.
According to Hugh Dalton, "The best organisation of world finance is that which secures the maximum social payoff from the operations which it conducts."
Principle of Maximum Social Advantage (MSA) ↓
The 'Principle of Maximum Social Advantage (MSA)' is the key 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 upward 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 payoff amongst reference to :-
- Marginal Social Sacrifice
- Marginal Social Benefits
This regulation is nonetheless based on the next assumptions :-
- All taxes upshot inwards sacrifice together with all world expenditures Pb to benefits.
- Public revenue consist of alone taxes together with 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 exercise goodness together with 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 upshot 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 amongst the community diminishes. As a upshot 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 touching on together with 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 higher upward diagram indicates that the Marginal Social Sacrifice (MSS) bend rises upwards from left to right. This indicates that amongst 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, together with amongst 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 exercise 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 together with to a greater extent than units of the commodity are made available to him, the social exercise goodness from each additional unit of measurement of world expenditure declines every bit to a greater extent than together with 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 together with 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 higher upward diagram, the marginal social exercise goodness (MSB) bend slopes downward from left to right. This indicates that the social exercise goodness derived out of world expenditure is reducing at a diminishing rate. When Earth expenditure was OM1, the marginal social exercise goodness was OB1, together with when Earth expenditure is OM2, the marginal social exercise goodness is reduced at OB2.
The Point of Maximum Social Advantage ↓
Social payoff 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 last higher, together with the marginal utility or social exercise goodness volition last lower.
At dot P social payoff is maximum. Now reckon Point P1. At this dot marginal social exercise 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 together with world expenditure. This is due to the argue that additional unit of measurement of revenue raised together with spent past times the authorities leads to increment inwards the internet social advantage. This province of affairs of increasing taxation together with world expenditure continues, every bit long every bit the levels of taxation together with expenditure are towards the left of the dot P.
At dot P, the marking of taxation together with world expenditure moves upward to OQ. At this point, the marginal utility or social exercise goodness becomes equal to marginal disutility or social sacrifice. Therefore at this point, the maximum social payoff is achieved.
At dot P2, the marginal social sacrifice S2Q2 is greater than marginal social exercise goodness P2Q2. Therefore, beyond the dot P, whatever farther increment inwards the marking of taxation together with world expenditure may convey 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 last to a greater extent than than marginal utility or social benefit. This shows that maximum social payoff is attained alone at dot P & this is the dot where marginal social exercise 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 exercise goodness of world expenditure together with the marginal social sacrifice of taxation are equated, i.e. where MSB = MSS.
This shows that to obtain maximum social advantage, Earth expenditure should last carried upward to the dot where the marginal social exercise goodness of the terminal rupee or dollar spent becomes equal to the marginal social sacrifice of the terminal unit of measurement of rupee or dollar taxed.
