land is perfectly inelastic. E=100000000000000000000, because no matter what the price change, there will be no change in quantity consumed.

Wait. What?

The supply of land is finite and non changing. Even if
price of land is one dollar, more cannot be produced. Lots of people will want it, and there will be a land shortage, so price will eventually go up (this is why manhattan real estate prices are so high).
If land is expensive, no one will want it, but the quantity of land does not change.

Obviously, ice cream is not like this. If lots of people want to buy ice cream, we can just make more of it, so total quantity of ice cream is very dependent on its price. For land, this is not the case.

I should not have said quantity consumed, that was wrong. What I meant was simply changes in prices of land will not lead to changes in quantity of land SUUPLIED, where as with most things: wine, cars, clothes, etc, have normal price elasticities, where if everyone wants jeans and they arent enough of them, someone will produce more.

ALso, I have only really talked about Supply Elasticities. Elasticities can also refer to demand.

ALSO, elasticity is percent change in Q over percent change in P, not what i wrote earlier. I always mix that up for some reason
