A cup of Starbucks Macchiato will cost you almost $6, and a similar cup at McDonald will cost about $3. The exotic Indonesian Civet Coffee will cost at least $25 per cup. What is the most that you are willing to pay for a cup? Is it worth to pay more? Do you have any consumer surplus on this consumption?

Please written by computer source Suppose that the demand curve for a product is given by Q = 100 −10p and the supply curve is Q = 10p. Assume that income effects (elasticities) are small so consumer surplus is a good measure of consumer welfare. (a) What is the equilibrium price and quantity with no distortions? (b) The government imposes a tax of $2.00 per unit sold. What is the new equilibrium quantity? Sketch the market equilibrium in a graph. (c) Given the tax what is the change in consumer surplus? What is the change in producer surplus? What is the change in government revenue? What is the net Dead Weight Loss from the tax? (d) Say the government proposes to use the revenue from the tax to pay for snacks in our last ECON 312A lecture. The total social benefits from the snacks would be $82.00. Will the tax increase overall welfare if the revenue is used to buy the snacks? What is the dollar value of the net gain or loss to society?

. Suppose that the demand curve is P = f(Q) = 30−0.2Q and the supply curve is P = g(Q) =0.1Q + 15. Find the equilibrium price and compute the consumer and producer surplus.
