Ok, the price of all capital goods, not just land, is a derivative of the amount of money you can make by renting it out. Can someone put this in a formula for me?
seriously? Multiply the rent by the interest rate?
peter schiff:
so at 1.5% interest rate that place was worth 600k? Am I missing something?
The idea is that the rent payments out in the future are less valuable than the rent paments nearer to the present, because of time-preference. To get the sale price, you add up all these rent payments. Eventually, at a certain point in the future, the rent payments have no value. Otherwise, the selling price of the capital good would be infinite. What you’re doing is discounting the rents out into the future progressively until they reach 0, and then adding them all up. The easy way to do this mathematically is to divide the rent by the interest rate. The time period of the rent has to match that of the interest rate. So, for example, annual rent and annual interest rate.
So given a pure interest rate of 5%, and a rent of $200, the sale price would be $4000.
You can see why this works by doing it mechnically. I’ll use much higher interest rate because otherwise it’ll take forever.
The concept is that the value of something is worth its future cash flows, each discounted by the interest rate. For an infinite cash flow, the value is deceptively easily calculated by the mentioned formula. The mathematical proof of the formula is more complex.
PV = CF / r
where
PV: Present Value
CF: Cash flow
r: discount rate
The value of the apartment in the second example would be 4000 / 0,015 = 266.666
Note that using the formula on capital goods is not strictly correct since no capital good lasts forever.
then in equilibrium we would expect that the sharecroppers would pay rent of (nearly) $250 per acre per year for the use of Farmer Smith’s land.
Only if by “equilibrium” one means an economy without profit. Otherwise, rational sharecroppers will pay nearly $250 x (1-going profit rate). Opportunity costs ftw.
The main question was answered by Zlatko. You do not multiply by the interest rate, you divide by it.
