The market model of fungible goods is based on maximizing the product number of items and price. It means that sellers will be increasing price as long the number of items sold also increases and will decrease price when the number of item sold drops, since the supply and demand is monotonic (someone willing to sell at $X will also sell at $X + anu positive number and someone willing to buy at $X will also buy at $X - any positive number) there is naturally a point where the number and price product is at the maximum. It still is affected by taxation and adding taxes moves prices up but this is besides the point.
None of the above applies to the land lease. The number of items to sell is 1, the value that the seller is maximizing is the lease value. If the price is too high then the land will stay unleased for longer time than acceptable to the particular seller and that may cause him to lower the price. The land will stay unleased longer because the prospective buyers will be choosing cheaper land elsewhere even if they otherwise would have chosen this particular parcel. But if all land owners are hit with the same tax then all of them can raise price and that will not affect unleased time because there won't be a price advantage for the buyer to go elsewhere.
>I have no idea in this particular case why it would be so, but relevant to economic incidence of taxes, sales taxes do change supply/demand curves of skittles bought on amazon.
Okay, we agree then. I was under impression you said they don't. Or you meant just sales taxes? What about VAT? What if there had been special Skittles tax in UK, would the manufacturer eat that since it's not a sales tax and the sellers are very inclined to just take a loss according to you?
