Suppose the demand for a product is given by QD=100-5P, where QD is quantity per year measured in kilogram and P is the price in AUD per kilogram. The supply curve for this product is given by QS=4P-8. Answer the following questions and provide a graph illustration. a) Determine the equilibrium price? b) Calculate the elasticity of demand and supply at the equilibrium price. c) Determine the consumer surplus and producer surplus at the equilibrium price? d) Suppose that the government imposes a floor price of A$15 and promises to buy any surplus (e.g., QS- QD ) on the market. Determine the new consumer surplus, the new producer surplus, and the government expenditure of this policy e) Instead of using the floor price, now the government imposes a A$3 tax on each kg sold, determine the market price after having this tax policy. f) Calculate the consumer surplus, producer surplus and tax revenue. g) Using the concepts of demand and supply elasticity, predict which party, the consumer or the seller, will generate a greater amount of tax revenue.
