45 Wages: Concept, Types and Wage Theories
This chapter opens the wages and wage legislation module. It covers the basic concepts of wages, the standard typology used in Indian labour economics, and the major wage theories — classical and modern — that explain how wages are determined.
45.1 What are Wages?
A wage is the price paid for the use of labour services — typically expressed per hour, per day or per month. The concept covers all forms of payment to a worker: cash, in-kind benefits, allowances, bonuses and incentives.
The Indian statutory definition in the Code on Wages, 2019, §2(y), is the most current. Wages mean all remuneration capable of being expressed in monetary terms, including basic pay, dearness allowance and retaining allowance, but excluding bonus, value of housing, contributions to social-security funds, conveyance allowance, sums paid to defray special expenses, house-rent allowance, overtime allowance, gratuity and any retrenchment compensation.
TipWhat Counts as ‘Wages’ under the Code on Wages, 2019
| Included | Excluded |
|---|---|
| Basic pay | Bonus |
| Dearness allowance | Value of housing |
| Retaining allowance | Conveyance, HRA, overtime |
| Other agreed remuneration | Gratuity, retrenchment compensation, social-security contributions |
The Code adds an important floor: where the excluded items exceed 50% of total remuneration, the excess is to be added back as wages. This prevents employers from inflating excluded heads to reduce statutory contributions.
45.2 Types of Wages — The Indian Labour-Conference Framework
Indian wage policy distinguishes four standard types, set out by the 15th Indian Labour Conference, 1957 and refined by the Supreme Court in Workmen of Reptakos Brett v. Management (1992).
TipFour Types of Wages in Indian Wage Policy
| Type | Definition | Source |
|---|---|---|
| Statutory minimum wage | Fixed by law to prevent exploitation; below this is illegal | Minimum Wages Act 1948 |
| Bare or basic minimum wage | Wage that meets bare physical subsistence — food, clothing, shelter | Below the minimum in welfare sense |
| Minimum wage (welfare sense) | Bare subsistence + minimum education, medical and other essentials | 15th ILC, 1957; Reptakos Brett (1992) |
| Fair wage | Above minimum; reflects industry’s capacity to pay; halfway between minimum and living | 1948 Fair Wages Committee |
| Living wage | Highest concept; supports a frugal but comfortable standard — health, decent housing, education for children, social protection, modest savings | Article 43 of the Constitution |
The 15th ILC set out the need-based minimum wage with five components:
TipFive Components of the Need-Based Minimum Wage (15th ILC, 1957)
| Component | Standard |
|---|---|
| Family unit | Earner + spouse + 2 children = 3 consumption units (children = 0.5 each) |
| Calorific intake | 2,700 calories per consumption unit per day |
| Clothing | 72 yards per family per year |
| Housing | Government-rental scheme rate for low-income workers |
| Fuel, lighting, miscellaneous | 20% of total wage |
The Supreme Court in Reptakos Brett (1992) added a sixth component — children’s education, medical needs, recreation and provision for old age (25% of the above). This judicially expanded need-based minimum wage is the standard reference today.
45.3 Indian Wage Hierarchy
TipWage Concepts in Order of Generosity
| Level | Concept | Comparison |
|---|---|---|
| 1 | Bare minimum / subsistence | Lowest — survival only |
| 2 | Statutory minimum wage | Legal floor |
| 3 | Need-based minimum wage | 15th ILC + Reptakos Brett — minimum in welfare sense |
| 4 | Fair wage | Above minimum, below living |
| 5 | Living wage | Constitutional aspiration — Article 43 |
45.4 Wage Theories — Classical and Modern
Six major theories try to answer the question: what determines the level of wages?
TipSix Major Wage Theories
| Theory | Lead names | Core claim |
|---|---|---|
| Subsistence theory | David Ricardo, Ferdinand Lassalle | Wages settle at the level needed to keep the worker alive and the supply replenished — the iron law of wages |
| Wages-fund theory | J.S. Mill | A pre-determined fund of capital is divided among available workers; wage = fund ÷ workers |
| Surplus value theory | Karl Marx | Worker is paid less than the value she produces; the surplus is appropriated by capital |
| Marginal productivity theory | J.B. Clark, A. Marshall | Wage equals the marginal value product of labour |
| Bargaining theory | John Davidson | Wages are settled by relative bargaining strength of employer and employees |
| Residual claimant theory | Francis Walker | Worker is the residual claimant after rent, interest and profit are paid |
| Behavioural / institutional | Veblen, Commons | Wages reflect institutional and behavioural factors, not pure economics |
45.4.1 Subsistence Theory — The Iron Law
David Ricardo’s Principles of Political Economy and Taxation (1817) and Ferdinand Lassalle’s elaboration give the most pessimistic account: any rise in wages above subsistence prompts population growth, which depresses wages back to subsistence. The theory has been criticised — population growth does not respond to wage changes that quickly, and historical experience shows long-run real-wage growth.
45.4.2 Wages-Fund Theory
John Stuart Mill’s Principles of Political Economy (1848) argued that the wage fund — the portion of capital advanced to workers — is fixed in the short run. Higher wages for some come at the cost of lower wages or unemployment for others. The theory was abandoned even by Mill himself in his later work.
45.4.3 Surplus Value Theory — Marx
Marx argued that capitalists pay workers only enough to reproduce labour power (subsistence + family), even though workers produce a value greater than this. The surplus value is the source of profit. The theory anchors radical and Marxist labour economics.
45.4.4 Marginal Productivity Theory — The Mainstream
J.B. Clark and Alfred Marshall developed the marginal-productivity account: under perfect competition, wage equals the marginal revenue product of labour. The theory is the workhorse of mainstream labour economics, but assumes perfect competition, full information and immediate adjustment — none of which holds in real labour markets.
45.4.5 Bargaining Theory
John Davidson’s Bargaining Theory of Wages (1898) emphasised the relative bargaining power of workers and employers. The actual wage falls within a range — between the maximum the employer is willing to pay and the minimum the worker is willing to accept — with the exact level set by bargaining. The theory underwrites the trade-union case for collective bargaining.
45.4.6 Residual Claimant Theory
Francis Walker’s theory treats the worker as the residual claimant — what is left after rent (to landlord), interest (to capital) and profit (to entrepreneur) have been paid from production. The theory has been criticised for treating profit as a residual to capital and wages as a residual to labour — a circular formulation.
45.4.7 Modern Additions
Modern labour economics adds:
TipModern Additions to Wage Theory
| Approach | Lead author | Core idea |
|---|---|---|
| Human capital theory | Gary Becker | Wages reflect investment in education, skills and experience |
| Efficiency wage theory | Akerlof, Stiglitz | Paying above market reduces shirking and turnover |
| Compensating wage differentials | Adam Smith | Wages compensate for non-wage features of jobs (risk, inconvenience) |
| Insider-outsider theory | Lindbeck, Snower | Insiders raise wages above market-clearing; outsiders bear the cost |
| Search and matching | Diamond, Mortensen, Pissarides | Wages emerge from frictional search process |
45.5 Wage Differentials
A wage differential is a difference in wages across occupations, industries, regions or worker characteristics. Five common types:
TipFive Types of Wage Differentials
| Type | What it covers | Example |
|---|---|---|
| Occupational | Across occupations | Doctor vs labourer |
| Inter-industry | Across industries | Software vs textiles |
| Inter-regional | Across regions | Mumbai vs rural Bihar |
| Inter-firm | Across firms in same industry | Tata vs small unit |
| Personal | Across individuals — gender, caste, religion | Gender pay gap |
The next chapter examines the determinants of these differentials in detail.
45.6 Wage Policy in India
India’s wage policy combines several instruments:
- Minimum Wages Act, 1948 — sets statutory floors for scheduled employments.
- Industrial Tribunals — fix industry-specific wages where disputes arise.
- Wage Boards (largely defunct) — tripartite industry wage-fixing.
- Pay Commissions — for central and state government employees.
- Code on Wages, 2019 — consolidates the four wage statutes (Minimum Wages, Payment of Wages, Equal Remuneration, Bonus) and introduces a floor wage.
The floor wage under the Code on Wages, 2019 — fixed by the central government — is the new innovation: a national minimum below which no state can fix its minimum wage.

- 15th ILC (1957) — need-based minimum: family = 3 consumption units; 2,700 calories; 72 yards cloth; rental housing; 20% misc. Reptakos Brett (1992) added 25% for education, medical, old age.
- Living wage = Article 43 aspiration.
- Wage theories: subsistence (Ricardo / Lassalle), wages-fund (Mill), surplus value (Marx), marginal productivity (Clark / Marshall), bargaining (Davidson), residual claimant (Walker), human capital (Becker), efficiency wage (Akerlof / Stiglitz).
- Wage differentials: occupational, inter-industry, inter-regional, inter-firm, personal.
