5. Suppose the demand for a particular wine can be described by the function qP(pa) = 100 - pa, where pa is the price paid by the consumer.
a) If a specific (quantity) tax of t = $10 is placed on Wine and this tax is paid by the consumer, find the demand for wine as a function of ps, the price paid to the producer. Recall that P = Ps + t. You are asked to find qP(ps).
b) If an ad valorem tax of 7 = 20% is placed on Wine and this tax is paid by the consumer, find the demand for wine as a function of ps, q(ps).
c) If the supply of the wine is described by the function qS(ps) = 2ps - 10, determine the equilibrium (price and quantity) in the market for the cases of (i) no tax, (ii) the specific tax t = $10, and (iii) the ad valorem tax 7 = 20%.
d) For the case of the specific tax t = $10, determine the incidence of the tax and calculate the deadweight loss of taxation.
e) For the case of the specific tax t = $10, find the price paid by the consumer and received by the firm, and the quantity sold when demand is q(pa) = 100 - pa and the monopolist has marginal cost mc = 5 + 2q.
