Pays the Tax?
The placement of a tax is not the same as its payment, and placement does not guarantee payment

Elasticity and the Tax
A change in price causes no change in quantity supplied; if sellers try to charge a higher price (trying to get buyers to pay some of the tax), a surplus will result, driving the price back down, and sellers pay the full tax
Suppose the current price of gasoline at the pump is $4 per gallon that 1 million gallons are sold per day. A politician proposes to add a $1 tax to the price of a gallon of gasoline. She says the tax will generate $1 million in tax revenues per day (1 million gallons x $1 per gallon - $1 million). In this situation, the politician is assuming that the demand for gasoline is:

The cross elasticity of demand between mouthwash and toothpaste is greater than zero
differences between the slope of a demand curve and the price elasticity.
The price elasticity of demand is the percentage change in quantity demanded divided by the percentage change in price. The value of price elasticity varies along a linear demand curve. The slope of a demand curve is the absolute change in the variable on the vertical axis (price) divided by the absolute change in the variable on the horizontal axis (quantity). The value of the slope remains constant along a linear demand curve. Therefore, the elasticity of demand and the slope of the demand curve are not the same.
Suppose a tax is imposed on the rental price of land. If the quantity supplied of land is constant regardless of price, who will pay the greater share of such a tax: buyers or sellers?
The sellers will pay the entire share of the tax.
