Oops. In my 2985 I made a mistake. I repeat it with CORRECTIONS and
EXPANSIONS.

CORRECTION
Introducing the South was a red herring. It merely signals that *in future*
replacement cost is cheaper. The argument in (a) still holds and the value
of the input remains 2 per unit. There is no reason why the output shuld
not be sold for 200 at the end of year 2 (matching the South's price
incidentally).
As a result of this mistake I conflated year 2 and year 3. It is in year
three that the actual input price of 1 would result in the 200 units of
output being valued at 180. (note that if improved corn from the South
arrived in year 1 then the Northerners could gloomily anticipate
devalorisation of their 100 units of OUTPUT.)

EXPANSION
I turn Ajit's complaint (2988) about the table over to Andrew.

Consider the following sequence.

Year 1 20 units of seed at 2 = 40 + other c 40 + v 40 + s 80 yeilding
100 units of corn valued at 200, unit output price 2.
Year 2 20 units of seed at 2 = 40 + other c 40 + v 40 + s 80 yeilding
200 units of corn valued at 200, unit output price 1.
Year 3 20 units of seed at 1 = 20 + other c 40 + v 40 + s 80 yeilding
200 units of corn valued at 180, unit output price 0.9.
Year 4 20 units of seed at 0.9 = 18 + other c 40 + v 40 + s 80
yeilding 200 units of corn valued at 178, unit output price 0.89.
year 5 the difference between input and output price is negligible.

At the beginning of year 2 the seed is genetically modified for free and
hence the output doubles; this is inheritable so the output remains at 200
in subsequent years. All the prices are actual prices (not necessarily
values I shall argue). The money wage remains constant as does the rate of
exploitation and other cet. pars.
If you accept these prices are intuitively acceptable, my question is this.
*How do they relate to value?*
The simplest solution is to say the values are identical with the prices.
But this suffers a grave defect if you hold a theory of value which relates
it exclusively to determinants in production and not circulation. For the
only year in which there was a change in the conditions of production was
year 2. Hence only in that year could a discrepency between the input value
and the output value be possible. The price changes in subsequent years
could not reflect value changes since in years 3, 4, 5, etc the conditions
of production are stable.
It might be concluded then that the only change in value occurred in year 2
and this then exercised a gravitational pull on prices which were out of
line with value for years 2 onwards but spiralled into it after 4 years or
so.
Probably this issue has already been addressed in the literature but I do
not know it.
