The market for land is competitive and in equilibrium at the rental rate of $500 per acre and the supply of land is perfectly inelastic at 1000 acres. If the demand for land falls and the rental rate falls to $400 per acre, the total economic rent on this land by .

Falls by $100,000

Explanation:

In this question, we are asked to calculate and state what happens when demand for land falls and as a result, there is also a fall in rental rate.

Firstly, we cost the total of 1000 acres. The price of 1000 acres is simply the multiplication of the 1000 acres by the $500 unit price= 500 * 1,000 = $500,000

We now calculate the price or worth of the land when demand falls

This is mathematically equal to 400 * 1000 = $400,000

Now, the net economic rent fall would be $500,00 - $400,000 = $100,000

Hence, there would be a fall of $100,000 as the demand for land falls

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30
