Day 17: Taxes on Other Commodities than Raw Produce

Key terms

Ricardo extends his tax-incidence machinery from corn to manufactured goods. The decisive distinction is not “farm versus factory” but necessary versus luxury.

Term	Meaning
Commodity tax	A charge tied to producing, selling, or consuming a good
Manufactured necessary	A non-food good workers need, such as basic shoes or clothing
Luxury	A good outside the labourer's necessary consumption bundle
Price pass-through	The tax-induced increase in the commodity's market price
Consumer incidence	A burden borne through a higher purchase price
Profit incidence	A burden borne through higher necessary wages and lower residual profits

The first rule: the taxed commodity becomes dearer

At the old price, a taxed producer earns less than capital elsewhere. Capital leaves until reduced supply supports a price covering the tax and ordinary profit.

This is the same competitive adjustment Ricardo used for corn. What happens next depends on who needs the commodity.

Worked miniature: shoes as a necessary

Suppose basic shoes cost £20 and a £4 tax raises the price to £24. A worker's household buys two pairs per year.

Item	Before	After tax
Price per pair	£20	£24
Two-pair annual cost	£40	£48
Extra necessary expense	£0	£8

If the worker's old wage covered only the necessary bundle, annual money wages must eventually rise by £8. The immediate consumer price effect becomes a wider profit effect.

£4 tax per pair x 2 pairs = £8 wage pressure

Necessaries and luxuries branch differently

A wine tax is paid by people who buy wine. A tax on basic clothing can affect every employer through the wage bargain, even employers who never purchase cloth for themselves.

Use the Lab to move the tax rate and wage share. Treat a larger wage share as a case where more of the taxed product belongs to workers' necessary consumption: the profit bar then shows the residual pressure on capital.

Why the distinction matters for foreign trade

If exported manufactures use labour whose necessaries are taxed, domestic money wages rise. That can make exports dearer relative to foreign goods and reduce the country's trading advantage.

A tax on a luxury consumed only at home does not enter the ordinary wage in the same way. It changes the luxury buyer's purchasing power rather than the general cost of employing labour.

tax on domestic necessity
        --> higher money wages
        --> higher domestic production pressure
        --> weaker export competitiveness

Collection does not determine incidence

Commodity taxes are convenient to collect from a small number of producers or sellers. But administrative convenience says nothing by itself about who pays economically.

Stage	Question
Collection	Who sends the money to government?
Pass-through	Does the commodity price rise?
Consumption	Is the good necessary or optional?
Distribution	Do wages respond, and do profits fall?

The full chain must be followed before naming the bearer.

Limits of the simple pass-through rule

Ricardo assumes reproducible goods, mobile capital, and enough time for supply to contract. In the short run, producers may absorb part of a tax; under monopoly, price can already exceed competitive natural price; and demand can fall sharply when buyers have substitutes.

The chapter's durable lesson is the method rather than a universal one-for-one prediction: trace cost, capital movement, supply, price, the worker's consumption basket, and finally income shares.

Key takeaways

A commodity tax tends to raise that commodity's price after supply adjusts.
Taxes on luxuries remain with consumers who choose them.
Taxes on manufactured necessaries can raise money wages and lower profits.
The same statutory tax can have a local price effect and an economy-wide distribution effect.
Collection from producers does not prove that producers bear the final burden.
