Demonstrate how if a public good is to be provided in some fixed amount or not provided at all, then a necessary and sufficient condition for provision to be Pareto efficient is that the sum of the willingnesses to pay (the reservation prices) exceeds the cost of the public good

. Using graphs, explain what will happen to the equilibrium price and the equilibrium quantity of a product in a perfectly competitive market as a result of each of the following scenarios: a. A rise in the number of buyers and a decrease in the cost of producing the product. b. Advances in the technology used to produce the product and a decrease in the price of a substitute.

Seasonal goods are goods that are consumed in larger quantities during some seasons than in other seasons, e.g. strawberries or hotel rooms near a beach during summer. While the price for strawberries is lowest during their season of highest consumption the price for hotel rooms near the beach is highest during their season of highest consumption. Explain why.

Given the original demand and supply equations for period 1, Qd = 120 - 6P and Qs = 12 + 4P solve the following:

Problem 1: The new and original price equilibrium given that the new demand and supply equations are Qd = 130 - 6P and Qs = 20 + 4P

Problem 2: The new and original quantity equilibrium given that the new demand and supply equations are Qd = 130 - 6P and Qs = 20 + 4P

Problem 3: The change in price equilibrium given that the new demand and supply equations are Qd = 130 - 6P and Qs = 20 + 4P

Problem 4: The change in quantity equilibrium given that the new demand and supply equations are Qd = 130 - 6P and Qs = 20 + 4P
