Introduction to Land Rent

Land Rent and Fertility
  • Fixed prices of inputs and outputs.
  • Zero economic profit.
  • Three types of land
  • high fertility
  • medium fertility
  • low fertility
  • Land to highest bidder.
  • Zero transport costs.

Increased Fertility.Why do rents change??

Land Rent and Accessibility
  • Again, fixed prices.
  • Central mktplace, costs t/mile to get there.
    Distance to mktplace u.
  • Competitive markets
  • All land is equally fertile, so production costs
    are the same everywhere.
  • A little algebra

6
Land Rent and Accessibility
  • ? PQ - C - tQu - R
  • So, if we have perfect competition, what happens
    to profits ??
  • They go to zero!
  • So
  • 0 PQ - C - tQu - R, or
  • R PQ - C - tQu

7
Land Rent and Accessibility
  • R PQ - C - tQu
  • What happens to rents as distance increases?
  • ?R/?u -tQ
  • Agt They fall. Why?
  • An example -- Worksheet for Figure 7.3
  • Fill in some numbers.

8
Land Rent and Accessibility
  • If we want to look at Rent/acre, we now have
  • RT PQ - C - tQu (T of acres)
  • What happens to rent/acre as distance increases?
  • R (PQ - C - tQu)/T
  • ?R/?u -tQ/T

Flexible Production
A farmer with fixed production methods faces a
linear rent curve.
Pick a point A, with a certain technology.
If we move 1 mile further away, well remain on
the red rent curve.
Rent
Since land is cheaper, here, if we can substitute
it for labor or capital, we can make higher
profits. Others can do the same, so the rent
well be bid UP.

Flexible Production
Do the same going the other way.
Rent
We get a convex land rent function.

Competing for Land
  • Producers of Type 1 will have the highest bids
    for land, up to two miles away.
  • Producers of Type 2 will have the highest bids
    for the land further away.
