On Wages

Source: David Ricardo, On the Principles of Political Economy and Taxation, Chapter V, "On Wages" • Course status: full course day for the Ricardo principles course

Key terms

Ricardo's wage chapter explains how the price of labour fits into his larger system. Labour has a natural price, tied to the cost of the goods workers need to live and raise families, and a market price, set by the immediate balance between demand for labour and the number of labourers seeking work.

TermMeaning
Natural wageThe wage that lets labourers subsist and keep the labouring population from shrinking
Market wageThe actual wage paid in the current labour market
NecessariesFood, clothing, lodging, and other goods treated as required for ordinary labouring life
Labour demandEmployers' need for workers, rising when capital is accumulating
Labour supplyThe number of labourers seeking work
Population adjustmentRicardo's long-run claim that high or low wages change the future supply of labour

Two prices of labour

Chapter IV separated natural price from market price for commodities. Chapter V applies the same map to labour. The market wage can rise above the natural wage when capital grows quickly and employers compete for workers. It can fall below the natural wage when workers are abundant relative to employment.

Ricardo is not saying actual workers live calmly at a neat equilibrium. He is describing the pressure that pulls wages toward a long-run level. The pull can be slow, painful, and historically uneven.

Natural wage is a moving cost

The natural wage is not a fixed pile of coins. If corn, rent, clothing, or lodging become dearer, workers need more money to buy the same subsistence. In Ricardo's system, that means the natural money wage rises.

dearer necessaries
      ->
higher natural money wage
      ->
larger wage bill for employers
      ->
pressure on profits

This is why wages sit between rent and profits in the course. Chapters II and III explained how food can become dearer at the margin. Chapter V shows why dearer food becomes a wage problem. Chapter VI then shows why higher wages squeeze profits.

Market wages can temporarily outrun natural wages

If capital accumulates quickly, employers hire more workers. Labour demand rises faster than labour supply, so market wages can stand above the natural wage for a time. Ricardo treats this as a prosperous but temporary condition: higher wages encourage population growth and bring more labour into the market later.

capital accumulates
      ->
more employment offered
      ->
market wage rises above natural wage
      ->
labour supply tends to expand later
      ->
market wage is pulled back down

The reverse is harsher. If employment demand weakens, market wages can fall below the natural wage. Workers cannot comfortably maintain their families, and Ricardo expects population pressure to ease only after distress has already occurred.

Worked miniature

Suppose the natural wage is 100, because a worker's necessary basket costs 100. If employers' demand for labour is 120 and labour supply is 95, the shortage pushes the market wage above the natural wage.

The numbers are a teaching model, not Ricardo's exact arithmetic. They show the distinction he needs: one force comes from the cost of subsistence, the other from immediate bargaining conditions.

Keep the chapter as a wage compass:

The two wage levels can move for different reasons. A harvest failure can raise the natural wage by making food dearer. A boom in capital accumulation can raise the market wage by making labour scarce.

Why this chapter matters later

Ricardo's later arguments about profits, trade, and taxes depend on this chapter. If wages were just a moral preference or a random bargain, his profit theory would not have a stable mechanism. By tying natural wages to necessaries, he can explain why dearer corn lowers profits even when manufactured prices do not rise.

This also explains why Ricardo cares so much about corn laws. A policy that keeps food dear is not just a food policy. In his model, it raises the natural wage and shifts distribution away from profits.

Key takeaways

Chapter V turns labour into a price with two levels. Natural wages are governed by the cost of maintaining labourers. Market wages are governed by the immediate supply and demand for labour. The gap between them creates pressure on population and future labour supply.

  • Natural wages rise when the goods workers need become dearer.
  • Market wages rise when labour demand exceeds labour supply.
  • Market wages can stay above or below natural wages for a time.
  • Ricardo expects population adjustment to pull market wages back toward natural wages.
  • The wage chapter is the direct bridge from rent and corn prices to the profit squeeze.

Checklist

A reader is ready to continue when they can explain wages with two clocks: the short-run labour market and the long-run cost of subsistence.
