Ap/econ 4070 3. 0af answers to midterm exam october 2011. What would be the incidence of a unit tax in a perfectly competitive market in which the demand curve had the equation and the supply curve had the equation. Equilibrium in a perfectly competitive market requires quantity supplied to equal quantity demanded, which means here that. 10 ps (1) where t is the unit tax on the good, and i have used the fact that pd = ps + t. if both sides are multiplied by ps(ps + t), equation (1) can be written. (40 4t)ps 10t = 0. When there is no tax, equation (2) becomes. 4(ps)2 = 40ps (2) (3) so that the equilibrium price is ps = p d = 10 when there is no tax at all. With a tax of , equation (2) becomes which has a solution of. 32ps 20 = 0 ps = 4 +

Could anyone help me understand how to go about solving this question? I would also like to learn how to set it up. Thank you.

1) Suppose the market demand curve for a good is represented by the linear equation Q = 100 - 0.5P. If the market price were to decrease from P = $40 to P = $30, then holding all other factors constant:

A)	the quantity demanded would increase by 10 units and total expenditures on the good would increase by $300

B)	the quantity demanded would increase by 5 units and total expenditures on the good would decrease by $650

C)	the quantity demanded would increase by 85 units and total expenditures on the good would increase by $2550

D)	the quantity demanded would decrease by 15 units and total expenditures on the good would decrease by $450

E)	the quantity demanded would decrease by 5 units and total expenditures on the good would increase by $150

F)	the quantity demanded would decrease by 25 units and total expenditures on the good would increase by $750
