(20 points in total) Suppose that the market demand curve is p = 80 - 8Qd, where p is the price per unit and Qd is the number of units demanded per week, and the market supply curve is p = 5+7Qs, where Q5 is the quantity supplied per week. a. b. C. d. e. Calculate the equilibrium price and quantity for a competitive market in which there is no market failure. Draw a diagram that includes the demand and supply curves, the values of the vertical- axis intercepts, and the competitive equilibrium quantity and price. Label the curves, axes and areas. Calculate both the marginal willingness to pay and the total willingness to pay for the equilibrium quantity. Calculate both the marginal cost of the equilibrium quantity and variable cost of producing the equilibrium quantity. Calculate the total surplus.

- Sam's profit is maximized when he produces shirts. When he does this, the marginal cost of the last shirt he produces is , which is than the price Sam receives for each shirt he sells. The marginal cost of producing an additional shirt (that is, one more shirt than would maximize his profit) is , which is than the price Sam receives for each shirt he sells. Therefore, Sam's profit-maximizing quantity corresponds to the intersection of the curves. Because Sam is a price taker, this last condition can also be written as .arrow_forwardWhy must total spending be equal to total income in an economy? Total income plus total spending equals total output. The value-added measurement of GDP shows this is true.

As an economic advisor to the governor, you have been asked to provide a recommendation on whether the minimum wage should be increased based on economic theory. Consider the labor market data provided. Prepare a brief report that: 1. Explains whether the labor market is currently efficient at the equilibrium wage of $15 per hour. How would you know? At equilibrium, what (dollar amount) is the Total Surplus this market provides? Show your rationale with numbers. 2. Analyzes the impact on total surplus in the market if the minimum wage is raised…arrow_forward
