7. The demand function for a good is QD=45-1.5PD and the supply function is Qs =-30+3Ps. A specific subsidy in the amount of $2.5 is paid to consumers. a. Find the equilibrium quantities before and after the subsidy. Plot these along with the relevant demands and supply on the graph below. b. Find the price that consumers pay to firms, and the total amount per unit that consumers pay (that is price - subsidy). c. What is the total amount of the subsidy paid out? e. Using the price change what is the subsidy incidence? f. Use the no-subsidy equilibrium and the point elasticity formula to compute supply and demand elasticities. What is the subsidy incidence? The formulas are on: page 46, equation 3.4 for demand; page 54, equation 3.9 for supply; page 62, equation 3.12 for tax incidence applies for subsidies too.
