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 populace authorities too amongst the adjustment of 1 amongst the other.

Budgetary activities of the regime results inwards transfer of purchasing ability from unopen to individuals to others. Taxation causes transfer of purchasing ability from revenue enhancement payers to the populace authorities, patch populace expenditure results inwards transfers dorsum from the populace authorities to unopen to individuals, hence fiscal operations of the regime sweat 'Sacrifice or Disutility' on 1 mitt too 'Benefits or Utility' on the other.
This results inwards changes inwards blueprint 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, so the fiscal operations are justified otherwise not.
According to Hugh Dalton, "The best organization of populace 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 cardinal regulation of Public Finance.
The Principle of Maximum Social Advantage states that populace 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 lawsuit inwards sacrifice too all populace expenditures atomic number 82 to benefits.
- Public revenue consist of entirely taxes too no other sources of income to the government.
- The regime has no surplus or deficit budget but entirely balanced budget.
- Public expenditure is acre of written report to diminishing marginal social practice goodness too taxes are acre of written report to increasing marginal social sacrifice.
Marginal Social Sacrifice (MSS) ↓
Marginal Social Sacrifice (MSS) refers to that amount of social sacrifice undergone past times populace due to the imposition of an additional unit of measurement of tax.
Every unit of measurement of revenue enhancement imposed past times the regime taxes lawsuit 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 lawsuit 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 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 amongst each additional unit of measurement of taxation, the marking of sacrifice besides increases. When the unit of measurement of taxation was OM1, the marginal social sacrifice was OS1, too amongst the increment inwards taxation at OM2, the marginal social sacrifice rises to OS2.
Marginal Social Benefit (MSB) ↓
While imposition of revenue enhancement puts burden on the people, populace expenditure confers benefits. The practice goodness conferred on the society, past times an additional unit of measurement of populace 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 practice goodness from each additional unit of measurement of populace expenditure declines every bit to a greater extent than too to a greater extent than units of populace expenditure are spent. In the beginning, the units of populace expenditure are spent on the around essential social activities. Subsequent doses of populace 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 practice goodness (MSB) bend slopes downward from left to right. This indicates that the social practice goodness derived out of populace expenditure is reducing at a diminishing rate. When the populace expenditure was OM1, the marginal social practice goodness was OB1, too when the populace expenditure is OM2, the marginal social practice 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, too the marginal utility or social practice goodness volition last lower.
At dot P social payoff is maximum. Now reckon Point P1. At this dot marginal social practice 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 populace expenditure. This is due to the argue that additional unit of measurement of revenue raised too spent past times the regime leads to increment inwards the cyberspace social advantage. This province of affairs of increasing taxation too populace 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 populace expenditure moves upward to OQ. At this point, the marginal utility or social practice 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 practice goodness P2Q2. Therefore, beyond the dot P, whatever farther increment inwards the marking of taxation too populace expenditure may convey downward 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 entirely at dot P & this is the dot where marginal social practice goodness of populace expenditure is equal to the marginal social sacrifice of taxation.
Conclusion ↓
Maximum Social Advantage is achieved at the dot where the marginal social practice goodness of populace expenditure too the marginal social sacrifice of taxation are equated, i.e. where MSB = MSS.
This shows that to obtain maximum social advantage, the populace expenditure should last carried upward to the dot where the marginal social practice goodness of the final rupee or dollar spent becomes equal to the marginal social sacrifice of the final unit of measurement of rupee or dollar taxed.
