Fоrecаst benefit is 100 × $20 = $2,000; reаlized benefit is 80 × $25 = $2,000. Which cоnclusiоn is supported?
A wildfire-smоke filtrаtiоn prоject аffects one representаtive household. There are two states of the world, each with probability 0.50. In this question only, income is measured in thousands of dollars. Severe-smoke state Normal state Income without project 75 135 Income with project, before any sure payment 106 150 a) Compute the surplus in each state and the expected surplus. (6 points)b) Compute the variance of income without the project and with the project. Does the project reduce risk? (8 points)c) Using the expected-surplus decision rule, suppose the probability of the severe-smoke state is p instead of 0.50. Find the breakeven p at which expected surplus equals a sure project cost of 24. (6 points)d) Return to the original 0.50/0.50 state probabilities. Assume U(c) = ln(c). Write the option-price equation and solve for option price. Use the feasible root, with positive consumption in both states. (10 points)e) Using the original 0.50/0.50 state probabilities, compute option value. If the sure project cost is 24, compare the expected-surplus decision rule with the option-price decision rule.
