Suppose that there is a 25% chance Riju is injured and earns $180,000, and a 75% chance she stays healthy and will earn $900,000. Suppose further that her utility function is
the following:
U = (Income) ³.
Riju's utility if she earns $180,000 is _ and her utility if she earns $900,000 is.

(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. How is the value of total surplus related to your calculations in parts c and d?arrow_forward
- 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. Every dollar that someone spends is a dollar of income for someone else. all of the abovearrow_forwardLabor Market Data Price $5 $10 $15 $20 $25 3,000,000 6,000,000 9,000,000 12,000,000 15,000,000 Qd 15,000,000 12,000,000 9,000,000 6,000,000 3,000,000 Price $30 $25 $20 $15 $10 $5 + +- x- 3 6 Do + + F 9 12 15 Quantity (In millions) Area of a triangle = 1/2* base *height Market Efficiency & Total Surplus Worth Publishers SCENARIO: The state government is considering raising the minimum wage from $15 per hour to $20 per hour over the next 3 years. 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

Gross Domestic Product (GDP) represents the total value of all goods and services produced by a country. The news reporter shows excitement because rising GDP signifies positive economic performance. Consumer spending has increased while businesses expand and new job opportunities become available. If the GDP rises, your delivery business will likely handle more packages as consumer purchasing increases. The increase in business activity will lead to more opportunities for your company to generate higher profits. You may need to take action by hiring additional staff and purchasing extra delivery vehicles or finding ways to improve your operation speed and efficiency to meet increased demand.arrow_forward
