Land-Tax

A land-tax sounds like one kind of tax, but Ricardo says its effects depend entirely on how the charge is calculated.

The chapter's central question is:

Does the assessment take part of rent,
or does it add a charge to producing the marginal corn?

Those two designs can share the name “land-tax” while producing opposite results.

If the state takes a fixed percentage of actual rent, it divides a surplus that already exists. No-rent land owes nothing, so the cost of producing the last required quarter of corn is unchanged.

If the state instead assigns every plot a fixed charge, no-rent land may also have to pay. That makes the marginal farm unprofitable at the old corn price.

Ricardo's lesson is methodological: follow the assessment rule to the price-setting margin. The legal name does not determine the economic effect.

Suppose three farms use the same capital and labour:

Now tax actual rent at 25 percent:

The marginal farm C still keeps its full 100 quarters. Its production conditions have not changed, so the corn price need not rise. The landlord bears the tax because the tax takes part of the differential surplus.

output on A       140
minus margin     -100
rent               40
25% rent tax       10
landlord keeps     30

Now replace the percentage with a fixed charge equivalent to 20 quarters on every plot. Farm C produces 100 quarters but can sell only 80 after meeting the charge.

At the old price index of 1.00, its revenue falls from 100 to 80. Competition cannot leave agricultural capital earning less than capital elsewhere, so either the farm exits or corn becomes dearer.

The restoring price is:

required revenue / saleable crop

100 / (100 - 20) = 1.25

Corn must rise by 25 percent for the marginal farmer to recover the former 100 units of revenue from 80 saleable quarters.

The farmer remits the assessment, but consumers ultimately pay through the higher price of raw produce.

Move the fixed assessment and watch the price response accelerate. Then change food's share of the wage basket: dearer corn creates stronger money-wage pressure when workers spend more of their income on food. Finally, compare rent at the old assessment with current rent to see how a frozen valuation exempts later rent growth.

A fixed assessment might begin with careful estimates of each property's rent. But society does not freeze on the valuation day.

Consider two properties initially assessed when each earned £40 of rent:

The nominal bill is equal, but the real burden is not. The first landlord keeps all rent growth above the old £40 valuation. The second loses a third of present rent.

Ricardo points to the English land-tax as an example of this drift. What was originally framed in relation to rent became, through fixed assessments, a highly unequal charge.

If a fixed land charge raises corn prices, who gains?

LANDLORD ON UNTAXED RENT GROWTH

higher corn price
      |
      v
higher value of agricultural surplus
      |
      v
current rent rises
      |
      v
old fixed assessment does not rise

Landlords may be peculiarly protected rather than specially burdened. The old assessment captures none of the later increase in rent, while higher corn prices can increase the money value of their remaining surplus.

This is the reverse of a true proportional tax on rent:

Corn is a major necessary in Ricardo's model. If its price rises, workers need more money to buy their customary bundle. The natural money wage therefore tends to rise.

Suppose corn rises 25 percent and food is half of the worker's necessary bundle. Holding everything else fixed, the immediate cost pressure on the whole bundle is:

25% corn rise x 50% food share = 12.5% wage pressure

This does not mean every worker instantly receives exactly 12.5 percent more. It isolates Ricardo's direction of adjustment: a tax that makes necessaries dearer presses natural wages upward, and higher wages press profits downward.

When faced with any tax on land, ask these questions in order:

1. Is the base actual rent, gross output, acreage, or an old valuation?
2. Does no-rent marginal land pay?
3. If it pays, what restores the ordinary agricultural profit?
4. Does the resulting price change affect workers' necessaries?
5. Has the assessment stayed aligned with current economic conditions?

MARGIN TEST

charge misses margin  -> divides rent -> landlord bears it
charge reaches margin -> raises cost  -> price transmits it
frozen valuation      -> burden drifts across properties

The same sequence works beyond Ricardo. Tax incidence depends on adjustment and alternatives, not merely on who receives the bill.

• A tax proportional to actual rent falls on landlords and does not raise corn prices.
• A fixed land assessment can reach marginal land even though marginal land pays no rent.
• When the margin is charged, corn prices rise until ordinary agricultural profit is restored.
• Consumers bear the first price effect; dearer necessaries can then raise wages and lower profits.
• A valuation frozen in time becomes unequal as actual rents change.
• Rising rent above an old assessment escapes the tax, potentially favouring landlords.
• The decisive question is whether the charge reaches the price-setting margin.
