Wages I: Concept and Types of Wages, Minimum, Fair and Living Wages, Factors Influencing Wages, Wage Theories and Wage Differentials
1. Concept and types of wages
A wage is the price paid for the services of labour. In ordinary usage "wages" are paid to manual workers by the hour, day, week or piece and "salaries" to clerical and managerial staff by the month, but the law treats both as remuneration for employment. The money wage (nominal wage) is the amount paid in money; the real wage is what that money buys, the money wage deflated by a price index. If a worker's money wage rises from ₹12,000 to ₹15,000 while the consumer price index rises from 100 to 125, his real wage is unchanged at ₹12,000 in base-year prices. That is why Indian wages carry a dearness allowance linked to the consumer price index for industrial workers, compiled by the Labour Bureau (base year 2016 since the series revised in 2020), and minimum wages carry a variable dearness allowance revised periodically. Wages may be time rates (paid for time worked, regardless of output), piece rates (paid per unit of output), or combinations such as incentive and premium plans (Unit II). Wages may be fixed by the employer unilaterally, by collective bargaining, by wage boards, by adjudication, by pay commissions for government employees, or by minimum-wage law.
2. Minimum, fair and living wages
The Committee on Fair Wages, appointed in 1948 by the Central Advisory Council, defined three levels that Indian wage policy still uses. The living wage is the highest: it should enable the earner to provide for his family not only the bare essentials of food, clothing and shelter but a measure of frugal comfort, including education for the children, protection against ill-health, requirements of essential social needs, and insurance against the more important misfortunes, including old age. The minimum wage is the lowest: it must provide not merely for the bare sustenance of life but for the preservation of the efficiency of the worker, and so for some measure of education, medical requirements and amenities. The fair wage lies between them: its lower limit is the minimum wage, and its upper limit is set by the capacity of the industry to pay; within that range it depends on the productivity of labour, the prevailing rates of wages in the same or neighbouring localities, the level of national income and its distribution, and the place of the industry in the economy of the country. Article 43 of the Constitution sets the living wage as a directive; the Minimum Wages Act 1948 and now the Code on Wages give the minimum wage the force of law.
| Need-based minimum wage norm (15th Indian Labour Conference, 1957) | Standard |
|---|---|
| Family unit | Three consumption units for one earner (the earner, spouse and two children) |
| Food | A net intake of 2,700 calories per average adult of moderate activity, as recommended by Dr. Aykroyd |
| Clothing | 18 yards of cloth per person per year, 72 yards for the family |
| Housing | The minimum rent charged by government for the lowest-income housing under the subsidised industrial housing scheme |
| Fuel, lighting and miscellaneous | 20 per cent of the total minimum wage |
| Added by the Supreme Court in Reptakos Brett (1991) | A further 25 per cent for children's education, medical requirements, recreation and festivals, provision for old age, and marriage |
3. Factors influencing wages
- Demand for and supply of labour: scarce skills command higher wages, and surplus labour depresses them.
- Cost of living: wages must rise with prices if real wages are to be maintained, which is the logic of dearness allowance.
- Prevailing rates in the industry and region, which employers follow to attract and retain workers.
- The employer's ability to pay, which depends on profitability, productivity and competition.
- Productivity of labour, the basis of productivity-linked wage agreements.
- Bargaining strength of unions, and the level at which bargaining takes place.
- Government regulation: minimum wages, pay commissions, wage boards and the tax system.
- Job requirements as measured by job evaluation: skill, effort, responsibility and working conditions.
- Social and psychological factors: custom, notions of fairness and status, and discrimination.
4. Wage theories
| Theory | Proponent | What determines the wage |
|---|---|---|
| Subsistence theory ("iron law of wages") | The Physiocrats and David Ricardo; the "iron law" named by Ferdinand Lassalle | Wages tend to the level that just keeps the worker and his family alive: above it, population rises and pushes wages down; below it, population falls and wages rise |
| Standard of living theory | A modification of subsistence theory | The customary standard of living of workers, not bare subsistence |
| Wages fund theory | Adam Smith's idea, developed by J. S. Mill | A fixed fund of capital set aside for wages divided by the number of workers; Mill recanted in 1869 after W. T. Thornton's criticism |
| Surplus value theory | Karl Marx | The worker is paid the value of his labour-power (its subsistence cost) but produces more; the capitalist appropriates the surplus value |
| Residual claimant theory | Francis A. Walker | Wages are what is left of the product after rent, interest and profit have been paid |
| Marginal productivity theory | J. B. Clark (The Distribution of Wealth, 1899), with Wicksteed and others | Under perfect competition, the wage equals the value of the marginal product of labour; employers hire until the two are equal |
| Discounted marginal productivity theory | F. W. Taussig | Wages equal the marginal product discounted for the time before the product is sold |
| Bargaining theory | John Davidson (1898) | Relative bargaining strength fixes the wage between an upper limit (the most the employer will pay) and a lower limit (the least the worker will accept) |
| Behavioural theories | Elliott Jaques (time-span of discretion); J. S. Adams (equity); Marsh and Simon; Herzberg; Vroom | Employees' perceptions of fair pay relative to others, the responsibility of the job and the psychological meaning of pay |
Later economic theories added the purchasing-power argument (associated with Keynesian economics) that cutting wages in a depression reduces demand and so employment; human capital theory (Theodore Schultz and Gary Becker) that wages reflect investment in education and training; and efficiency-wage theories (for example Carl Shapiro and Joseph Stiglitz, 1984) that employers may pay above the market-clearing wage to reduce shirking, turnover and recruitment costs and to raise morale. Monopsony — a single or dominant employer of labour in a locality — explains why a minimum wage above the market rate can, within a range, raise both wages and employment, a point used in defence of minimum-wage laws.
5. Wage differentials
Wage differentials are differences in wages between workers, jobs, firms, industries and regions. Occupational differentials reflect differences in skill, training, responsibility and hazard; inter-firm differentials arise within one industry and locality from differences in efficiency, size, ability to pay and union strength; inter-industry differentials reflect productivity, capital intensity, profitability and unionisation; regional differentials reflect the cost of living, the supply of labour and the level of development; and personal differentials arise from age, experience, sex, caste and other characteristics, including discrimination. In India the sharpest differential is between the organised and the unorganised sector, and between regular salaried, casual and self-employed work. Adam Smith, in The Wealth of Nations (1776), explained "compensating" differentials by five circumstances of employment: its agreeableness or disagreeableness, the ease or difficulty and expense of learning it, its constancy or inconstancy, the small or great trust reposed in the worker, and the probability or improbability of success in it. J. E. Cairnes's idea of "non-competing groups" explained why differentials persist: workers cannot freely move between occupations separated by barriers of education, capital and social status.
Key takeaways
- Money wage versus real wage (money wage deflated by a price index); time, piece and incentive wages; dearness allowance linked to the consumer price index for industrial workers (Labour Bureau, base 2016).
- The Committee on Fair Wages (1948): minimum wage (subsistence plus efficiency), living wage (frugal comfort, education, health, insurance) and fair wage between them, bounded by capacity to pay; Article 43 sets the living wage as a goal.
- The need-based minimum (15th ILC, 1957): three consumption units, 2,700 calories, 72 yards of cloth for a family, the subsidised-housing rent, 20 per cent for fuel and miscellaneous; Reptakos Brett (1991) added 25 per cent for education, medical care, recreation, old age and marriage.
- Theories: subsistence (Ricardo; Lassalle's iron law), standard of living, wages fund (Mill, recanted 1869), surplus value (Marx), residual claimant (Walker), marginal productivity (J. B. Clark), discounted marginal productivity (Taussig), bargaining (Davidson), behavioural (Jaques, Adams); later human capital, efficiency wages and monopsony.
- Differentials: occupational, inter-firm, inter-industry, regional and personal; Adam Smith's five compensating circumstances (1776); Cairnes's non-competing groups; in India, above all, the organised–unorganised gap.

Show answer
Answer: B — Francis A. Walker
Walker held that wages are the residue of the product after rent, interest and profit have been paid, so that workers gain from any rise in productivity. Clark gave marginal productivity, Davidson the bargaining theory and Mill the wages fund theory.According to the Committee on Fair Wages, the upper limit of the fair wage is set by
Show answer
Answer: D — the capacity of the industry to pay
The fair wage lies between the minimum wage (its lower limit) and the capacity of the industry to pay (its upper limit); within that band productivity, prevailing rates, national income and the industry's place in the economy decide it. The living wage is the ideal, not the limit of the fair wage.Which thinker named the "iron law of wages"?
Show answer
Answer: D — Ferdinand Lassalle
Ferdinand Lassalle gave the subsistence theory the name "iron law of wages". Marx developed surplus value, Smith explained compensating differentials and Taussig the discounted marginal productivity theory.In Workmen of Reptakos Brett and Co. v. Management (1991), the Supreme Court added to the need-based minimum wage a further component of
Show answer
Answer: B — 25 per cent for children's education, medical needs, recreation, old age and marriage
Reptakos Brett added 25 per cent of the total minimum wage for children's education, medical requirements, minimum recreation including festivals and ceremonies, provision for old age, and marriage. The 20 per cent for fuel, lighting and miscellaneous items was already one of the 1957 norms.Which of these are among Adam Smith's five circumstances explaining wage differentials? Select all that apply.
Show answer
Answer: B — The agreeableness or disagreeableness of the employment; C — The constancy or inconstancy of employment; D — The trust reposed in the worker
Smith's five are agreeableness, the ease and cost of learning, constancy of employment, the trust reposed, and the probability of success. Union density is a modern explanation of inter-industry differentials, not one of Smith's circumstances.Assertion (A): J. S. Mill abandoned the wages fund theory in 1869. Reason (R): The wages fund theory implied that trade unions could not raise wages in general, because the fund was fixed.
Show answer
Answer: B — Both A and R are true, but R is not the correct explanation of A
Both statements are true, but R does not explain A. Mill recanted after W. T. Thornton's criticism that there is no predetermined fund; the implication that unions were powerless was a consequence of the theory, not the reason Mill gave it up.Assertion (A): Where a single employer dominates a local labour market (monopsony), a minimum wage within a certain range can raise both wages and employment. Reason (R): A minimum wage set above the market wage always reduces employment, in every kind of labour market.
Show answer
Answer: C — A is true, but R is false
A is true: a monopsonist pays below the value of the marginal product, and a well-set minimum wage can raise both pay and employment. R is false: the prediction that a minimum wage reduces employment holds under perfect competition, not in every market; under monopsony it reverses within a range.The need-based minimum wage norms of 1957 assumed a standard family of
Show answer
Answer: D — three consumption units for one earner
The 15th Indian Labour Conference took the standard working-class family as the earner, his spouse and two children, counted as three consumption units, with the earnings of women, children and adolescents disregarded.A worker's money wage rose from ₹12,000 to ₹16,500 while the consumer price index rose from 100 to 150. What is his current real wage in base-year prices, in rupees? Type the number.
Numerical answer — type the value.
Show answer
Answer: 11000
Real wage = 16,500 × (100 ÷ 150) = ₹11,000. Although his money wage rose by 37.5 per cent, prices rose by 50 per cent, so his real wage fell from ₹12,000 to ₹11,000 — which is why dearness allowance is linked to the price index.How many calories per average adult of moderate activity did the 1957 need-based norms adopt? Type the number.
Numerical answer — type the value.
Show answer
Answer: 2700
The norms adopted a net intake of 2,700 calories per average Indian adult of moderate activity, following Dr. Aykroyd's recommendation, together with 18 yards of cloth a year per person and 20 per cent of the total for fuel, lighting and miscellaneous items.
