I. There are three qualities of land; each requires one dose of labor
plus capital per acre in order to produce corn. One dose of labor
plus capital costs £12. The table shows the amount of each kind
of land and the amount of corn it can produce per acre. You cannot
produce more corn per acre by applying more than one dose of labor
plus capital. (10 points)
Acres Output/acre Rent and Price for part A
Rent and Price for part B
Grade 1 100 4 bushels 4£/acre
£12/acre
Grade 2 100 3 bushels 0£/acre
£6/acre
Grade 3 200 2 bushel 0£/acre
0£/acre
Price of corn £4/bushel
£6/bushel
Total Rent £400/year
£1800/year
A. A total of 600 bushels of wheat is being produced. Show the price
of wheat, rent per acre of each grade of land, and total rent
collected on all land.
To produce 600 bushels
requires all of the grade 1 and some of the grade 2, so grade 2 is
the marginal land and pays no rent. It costs £12 to produce 3
bushels of corn on grade 2 land, so the price of corn is
£4/bushel. Grade 1 land produces 4 bushels per acre at the same
cost, which sells for £16 and costs £12, leaving £4
for rent. Another way of calculating it is to note that grade 1 land
produces 1 bushel/acre more than the marginal land at the same cost,
so the corn rent is 1 bushel/acre, implying a money rent of
£4/acre. There are 100 acres of grade 1 land, and only it pays
rent, so total rent is £400.
B. As in A, except that demand has increased to
800 bushels
Now the marginal land is grade
3, so it pays no rent; it costs £12 to produce 2 bushels of corn
on marginal land, so corn is £6/bushel. Grade 2 land produes one
bushel more, so rents for £6/acre, grade 1 produces two bushels
more, so rents for £12/acre. 100 acres x £12/acre + 100
acres x £6/acre = £1800.
II: (p. 33): "All commodities which are produced
by very valuable machinery, or in very valuable buildings, or which
require a great length of time before they can be brought to market,
would fall in relative value."
(10 points)
All of these correspond to
having a high ratio of capital to labor. In the case of valuable
machinery or buildings, there is lots of fixed capital; in the case
of a long production cycle, the ratio of circulating capital to labor
is high. In either case, an increase in wages will increase the
production cost of such capital intensive goods by less than it
increases the production cost of goods with an average capital/labor
ratio, so the former will fall in relative value relative to the
latter.
III: (p. 69-70): The friends of humanity cannot
but wish that in all countries the labouring classes should have a
taste for comforts and enjoyments, and that they should... (5
points)
Ricardo believes that in the
long run, wages tend towards that wage at which the laboring
population just reproduces itself. If wages are higher than that, the
number of workers increases, driving wages back down, vice versa if
lower--the so-called iron law of wages.
What that wage is depends in part on the tastes of the workers. If
the average worker doesn't think he can afford to marry and have
children until he is living quite well, the natural wage will end up
high--which is a good thing, since it means that the bulk of the
population is (relatively) well off. If workers have very modest
tastes, the natural wage will be low--and when something goes wrong,
pushing wages temporarily below it, people starve.
IV. (p. 83): The natural tendency of profits then
is to fall; for in the progress of society and wealth, the additional
quantity of food required is obtained by the sacrifice of more and
more labour. (10 points)
In the progress of society,
population expands, quantity of corn produced increases, and
agriculture is forced onto worse and worse marginal land. Hence the
cost in labor of producing a bushel of corn increases. Hence the
natural wage, which is in large part determined by the price of food,
rises. The result in agriculture is obvious--the farmer is getting
less corn from an acre of marginal land, must pay the same amount of
corn to his workers, so has less left over for his profit. The same
thing happens in manufacturing, because the manufacturer must pay his
workers a larger value for wages--which means a larger fraction of
their output, since the value of the output doesn't change--by
Ricardo's definition of value, constructed so that value only changes
when the inputs needed to produce something
change.
V. (p. 148): This circumstance is curious. By
taxing the profits of the farmer you do not burthen him more than if
you exempted his profits from the tax, and the landlord has a decided
interest that his tenants' profits should be taxed, as it is only on
that condition that he himself continues really untaxed. (10
points)
Version 1: profit on
manufacturing money not taxed.
If you tax the farmer's profits, the price of corn must increase by
the amount of the tax, so he still gets the same profits as everyone
else. Like other capitalists, he pays the tax in the higher prices of
everything.
The tax does not affect the landlord's corn rent, since it is
determined by the difference between output on his land and output on
marginal land with the same input--and since the same input means the
same amount of capital, a tax on profit collects the same amount from
both kinds of land, hence leaves the difference unchanged. If the
profit on corn is untaxed, the same corn rent means the same money
rent, and the landlord pays the tax in higher prices like everyone
else. If it is taxed, corn is worth more, so the landlord's money
rent goes up, compensating him for the cost of paying higher prices
for everything he buys.
Version 2: profit on manufacturing money taxed.
Now the price of taxed goods stays the same (since it is the ratio of
the cost of producing them to the cost of producing money, and both
are taxed, leaving the ratio unchanged). The price of untaxed goods
falls. If you tax the farmer's profits he pays the tax directly, if
you don't the price of corn falls and he pays indirectly by getting
less for his corn. Corn rent is still unaffected for the same reason
as before. So if you tax the farmer's profits, the landlord's money
rent stays the same, prices are the same, so he does not pay the tax.
If you don't tax the farmer's profits, the landlord's money rent goes
down (because the price of corn goes down), so he does pay the
tax.
VI: Do either A or B: (on the back)
(10 points)
A. (p. 98): Thus, then, it appears that the improvement of
manufacture in any country tends to alter the distribution of the
precious metals among the nations of the world: it tends to increase
the quantity of commodities, at the same time that it raises general
prices in the country where the improvement takes place.
England and France are
currently in equilibrium with regard to trade; each exports and
imports the same amount (measured in real money--gold). England makes
an improvement in manufacturing something, lowering its money cost of
manufacture. As a result, the amount of that good exported to France
increases (or the amount imported from France decreases), so gold
starts flowing into England from France, driving up prices in
England. The process starts when the price change is just enough to
bring trade back into balance--at which point prices are higher in
England, there is more gold in England and less in France, and total
production of commodities is higher due to the increased productivity
due to the improvemente of manufacture.
B. (p. 276): The demand for labour will continue to increase with an
increase of capital, but not in proportion to its increase; the ratio
will necessarily be a diminishing ratio.
As the amount of capital
increases, so does the amount of labor, increasing the demand for
corn and pushing agriculture onto worse and worse marginal land. So
the value of corn rises, so the value of wages rises, to the value of
profit and the profit rate fall.
Since labor is becoming more expensive and capital cheaper, capital
intensive forms of production are becoming more attractive relative
to labor intensive forms of production, so the increased capital
tends to go into more and more capital intensive forms of production,
where it employs less labor than previous increases.
