64 Types of Labour Markets: Perfectly Competitive vs Imperfect, Monopsony, Bilateral Monopoly, Internal vs External, Primary vs Secondary (Dual), Segmented (Race / Gender / Caste), Formal vs Informal, Local / National / Global, Spot vs Career, Gig and Platform Markets

64.1 A Mosaic of Markets, Not One

The “labour market” is in reality a mosaic of many markets — a brick-kiln worker in Bihar and a Bangalore software engineer participate in markets that hardly meet. Economists classify labour markets by structure (competitive, monopsony, bilateral monopoly), by location (internal vs external, local vs global), by quality of jobs (primary vs secondary), by segmentation along race / gender / caste lines, by formality (formal vs informal) and by new forms like the gig and platform economy. Understanding these typologies is essential to diagnosing employment and wage outcomes.

64.2 1 · Classification by Structure

64.2.1 A · Perfectly Competitive Labour Market

Perfectly Competitive Labour Market

Feature	Substance
Buyers	Many small employers
Sellers	Many homogeneous workers
Information	Perfect
Wage	Determined by supply-demand intersection; firm is wage-taker
Mobility	Free
Outcome	MRP_L = W; efficient allocation

64.2.2 B · Monopsony

A monopsony in the labour market is a single buyer — a town with one factory. The monopsonist faces an upward-sloping supply curve, so MFC > W. Profit maximisation hires fewer workers at lower wage than competitive equilibrium.

64.2.3 C · Bilateral Monopoly

A bilateral monopoly occurs when a single union (monopoly seller) bargains with a single employer (monopsony buyer). Wage and employment are indeterminate within a range — depending on bargaining power.

64.2.4 D · Oligopsony / Oligopoly

Few buyers / sellers — e.g., few car-makers competing for engineers.

64.3 2 · Internal vs External Labour Markets

Internal vs External Labour Markets (Doeringer-Piore 1971)

Aspect	Internal	External
Scope	Within firm	Outside firm
Pricing	Administrative — pay scales, promotions	Market-determined
Allocation	Internal promotions	External hiring
Mobility	Promotion ladders	Hiring/firing
Examples	Government cadres, large PSUs	Casual labour market, gig market

64.4 3 · Primary vs Secondary (Dual Labour Market)

Dual Labour Market (Piore)

Aspect	Primary	Secondary
Wages	High	Low
Job security	High	Low
Working conditions	Good	Poor
Career ladder	Yes	No
Mobility upward	Possible	Difficult
Examples	Salaried staff at IT firms, banks	Construction labour, contract workers

PYQ trap — Dual Labour Market

Piore’s Dual Labour Market theory says workers are stuck in either primary (good) or secondary (bad) labour markets with little mobility between them — explaining persistent inequality.

64.5 4 · Segmented Labour Markets

Beyond duality, segmentation theory explains that markets are divided along lines of race, gender, caste, religion, region. Movement between segments is restricted.

Segmentation Examples

Axis	India Example
Caste	Manual scavenging (predominantly Dalit)
Gender	“Women’s jobs” — nursing, domestic, garment
Religion	Muslim concentration in informal sector
Region	South Indian software engineers vs North Indian construction labour
Migration status	Internal vs migrant; local protectionism

64.6 5 · Formal vs Informal Labour Markets

Formal vs Informal

Aspect	Formal	Informal
Contracts	Written	None or oral
Wages	Regular, statutory	Variable, often below minimum
Social security	Available	Limited
Working hours	Regulated	Often unregulated
Indian share	≈ 20 %	≈ 80 %

64.7 6 · Spatial Classification

Spatial Types of Labour Market

Type	Substance	Example
Local	Confined to small area	Domestic workers in a city
Regional	Within a region or state	Plantation labour in Kerala
National	Spans country	Civil services
International	Cross-border	IT services (H-1B visa)

64.8 7 · Spot vs Career Labour Markets

Spot vs Career Markets

Aspect	Spot Market	Career Market
Duration	Day, week, season	Multi-year
Wage	Market-clearing daily	Career-based pay scale
Relationship	Transactional	Long-term
Examples	Daily-wage labour, gig	Tenure-track academia, civil services

64.9 8 · Gig and Platform Labour Markets

The rise of digital platforms (Uber, Swiggy, Zomato, Urban Company, Freelancer, Upwork, Amazon Flex) has created a new type of labour market — gig and platform work — sitting at the boundary of formal and informal, employee and self-employed.

64.9.2 Features of Gig Work

No statutory employer.
Algorithmic management — pricing, ratings, deactivation by algorithm.
Triangular relationship — worker, platform, customer.
Piece-rate or commission.
No social security under traditional law (now extended via Code 2020).
Often informal in social-security terms even if formal in payment trail.

64.10 9 · Karnataka Gig Workers’ Welfare Bill 2024

Karnataka pioneered a gig workers welfare cess on aggregators to fund welfare for platform workers — a model being studied by other states.

64.11 10 · Rajasthan Platform-Based Gig Workers Act 2023

Rajasthan became the first state to enact a Platform-Based Gig Workers (Registration and Welfare) Act 2023 — establishing a board, registration, welfare fund.

64.12 11 · Labour Markets by Skill Level

By Skill

Type	Indian Examples
Unskilled	Construction helpers, agricultural labour
Semi-skilled	Carpenters, drivers
Skilled	Mechanics, electricians
Highly skilled	Engineers, doctors, IT professionals

64.13 12 · Labour Markets by Industry / Occupation

By industry — agricultural labour market, construction labour market, IT labour market, healthcare labour market. By occupation — teacher market, doctor market.

64.14 13 · Lewis Dual-Economy Model (1954)

W. Arthur Lewis (1954) — Nobel 1979 — described a dual economy with a traditional (subsistence agricultural) sector with surplus labour, and a modern (capitalist industrial) sector that absorbs labour at constant wage until surplus exhausts. Foundational model of structural transformation.
