The market for smart phone applications is characterized by the following demand and supply curves. QD = D(P) = 15 - 3P Qs = S(P) = 5 + 10P (a) Calculate the equilibrium price and quantity for this market. [3 marks] (b) The government is considering introducing a per unit subsidy of t on each electric car that is purchased. Suppose that the statutory incidence of this subsidy will be on buyers. Using the equilibrium conditions, D(Pn - t) = S(Pn) = Q* (i.e. that demand equals supply in equilibrium), derive an equation in terms of e, and ea that describes what fraction of the subsidy is borne by buyers/consumers. [6 marks] (c) Suppose that the unit tax is set at t = 0.1 per unit. What is the excess burden of this tax per dollar of revenue raised? [8 marks] (d) Suppose that we incorrectly assumed that supply was perfectly elastic and there was no impact of the tax on the equilibrium price received by sellers. Would EB/Tax Revenue be higher or lower than what you calculated in part (c)? In 1-2 sentences, explain your answer. [8 marks]
