Vicious circle of poverty

Topic: Poverty and Inequality: Measurement and Policy · NCERT: Beyond NCERT

Meaning

The vicious circle of poverty is Ragnar Nurkse's (1953) idea that "a country is poor because it is poor". Low income leads to low saving, low investment and low productivity, and these in turn keep income low. So poverty is both the cause and the result of itself.

It matters because it explains why poor countries do not grow on their own. It also supports the case for an outside push, such as foreign capital, a "big push" of investment or better technology. The note links the circle to a simple growth formula: g = s / v (growth of income = saving rate ÷ capital-output ratio).

Explanation

How the circle works

• The core chain: low income → low saving → low investment → low productivity → low income again.
• Two key words sit inside the chain:
• Capital formation means adding to the stock of machines, tools, roads and buildings. It is the "investment" link in the circle.

• Productivity means output per worker. It rises only when each worker has more capital and skill to work with.

• Nurkse said the circle runs from two sides: the supply side and the demand side.

Supply side (the saving circle)

• Low income → low saving → low investment (capital formation) → low productivity → low income.
• Poor families spend almost all their income on food and other basic needs.
• Very little is left to save, so banks have little money to lend for new factories or farm tools.

• Without new capital, output per worker stays low, so income stays low.

• The problem here is a shortage of savings.

Demand side (the market circle)

• Low income → low purchasing power → small market → weak inducement to invest → low productivity → low income.
• Purchasing power is how much people can actually buy.
• Inducement to invest is a firm's reason to invest. It is the hope of selling its extra output.

• A shoe factory will not expand if most people cannot afford shoes.

• The problem here is a shortage of buyers. So investment stays low even when savings exist.

Worked example and how to break the circle

• Use g = s / v. Here the capital-output ratio (v) is how many rupees of capital are needed to produce ₹1 of extra output each year. (This is an illustration only.)
• Say saving is 5% of income and v = 4.
• Income grows by 5 ÷ 4 = 1.25% a year.
• If population grows by 2% a year, per capita income (income per person) falls by about 0.75% a year.

• Lower per capita income means even less saving next year. The circle closes.

• Ways to break it:

• Raise s: more domestic saving, or external finance (foreign aid, loans or investment) to fill the saving gap.
• Lower v: better technology, so each rupee of capital produces more output.
• Either step lets income growth run ahead of population growth.
• Big push: a large, coordinated wave of investment in many sectors at once. Each sector then creates demand for the others. This answers the demand-side circle.

In India

No single institution "measures" the vicious circle. It is a theory. But India's history shows each link clearly, and India's recent data shows the circle can be broken.

• How the circle was set up (historical causes):
• Colonial legacy: de-industrialisation (British factory goods destroyed Indian handicrafts) and stagnant farming left a weak base in 1947.
• Slow growth until 1980. Growth was well below what was needed to absorb a growing population. This is the worked example above in real life.

• Population pressure on land and jobs kept per capita income low. This is the Indian form of the Nelson trap.

• Supply-side links in farming:

• Disguised unemployment: more people work on a farm than are needed. If some leave, output does not fall, so their marginal product (the extra output from one more worker) is zero. Each person earns very little, so each person saves very little.

• Small, fragmented holdings are too small to use machines or get credit, so capital per worker stays low.

• Weak investment in rural areas (NCERT, Class 11, Rural Development):

• Farm growth slowed to about 3% a year in 1991–2012. Agriculture and allied GVA (gross value added: value of output minus the cost of inputs) grew only about 2% in 2023-24.

• Scholars blame falling public investment since 1991 in irrigation, roads and research. This is the "low investment → low productivity" link.

• Evidence that the circle can be broken:

• The Multidimensional Poverty Index (MPI) counts deprivations in health, education and standard of living, not just income. It is released by NITI Aayog. India's MPI headcount fell from 29.17% (2013-14) to 11.28% (2022-23), and about 24.82 crore people escaped poverty [1].

• World Bank: extreme poverty at $2.15 a day fell from 16.2% (2011-12) to 2.3% (2022-23), which lifted about 171 million people [2][3].

• Neighbours (NCERT, Class 11, Comparative Development Experiences):

• China spread rural health services, carried out land reforms and shared food more equally through communes before the 1978 reforms. This human base helped growth reach the poor, and poverty fell for good.
• Pakistan's poverty was over 40% in the 1960s, fell to 25% in the 1980s, then rose again. Its gains rested on good harvests and remittances (money sent home by workers abroad), so each bad year pulled people back into the circle.

Don't confuse with

• Poverty trap: the vicious circle says all poor stay poor. A trap has a threshold (a minimum level). Only those below it stay stuck, so a one-time push above it can free them for good.
• Low-level equilibrium trap: this is Richard Nelson (1956), not Nurkse. Here the circle closes through population: any rise in per capita income causes faster population growth, which pulls income back down. Nurkse's circle closes through saving and markets.
• Big push: this is a remedy (coordinated investment in many sectors at once). It is not the problem. It answers Nurkse's demand-side circle.
• Supply-side vs demand-side circle: the supply side is about too little saving. The demand side is about too small a market, where investment stays low even if savings exist.

Prelims Hooks

• "A country is poor because it is poor" is Ragnar Nurkse (1953). It is not Nelson, and it is not Banerjee-Duflo.
• Supply-side circle: low income → low saving → low capital formation → low productivity → low income.
• Demand-side circle: low income → low purchasing power → small market → weak inducement to invest → low productivity → low income.
• g = s / v: with s = 5% and v = 4, income grows 1.25%. With population growing 2%, per capita income falls by about 0.75%. You can break the circle by raising s or lowering v.
• Trap: "Rising per capita income triggers faster population growth" describes Nelson's low-level equilibrium trap (1956), not Nurkse's circle.
• India's MPI headcount: 29.17% (2013-14) → 11.28% (2022-23); 24.82 crore escaped [1].

Mains Points

• Circle vs trap, and the policy choice. Nurkse's circle supports a big push for everyone. Banerjee and Duflo's randomised trials in Poor Economics (2011; Nobel 2019) found that traps exist only for some people and some situations. So India needs targeted tools, and should not rely only on blanket subsidies:
• graduation programmes (an asset such as livestock, plus training) for the ultra-poor;

• nutrition and health cover where the threshold really binds.

• Breaking both sides of the circle in rural India. Farm growth fell to about 2% (2023-24), and public investment has declined since 1991.

• On the supply side, India needs more public investment in irrigation, roads and research. It also needs formal credit, so farmers can escape the moneylender debt trap.

• On the demand side, it needs non-farm rural jobs that raise purchasing power and widen the market.

• Lessons from neighbours. China built health, land and food security before growth, and its poverty fell for good. Pakistan's gains rested on harvests and remittances and were reversed. India's sharp MPI fall (29.17% → 11.28%) [1] shows that better basic services can break the circle. But social exclusion (STs have the highest MPI incidence, followed by SCs) and the concentration of poverty in a few states (Bihar, Jharkhand, UP, MP, Odisha) show that the circle has not been broken for everyone yet.
