ECO 7113 Practice Problem Len Cabrera Page 1 of 4 Ralph owns a lottery that will pay $100, $200, or $300 with equally likely odds. His utility function is -exp(0.01$). Determine Ralph's certainty equivalent. Next suppose Ralph sells a stake in this lottery to his cousin. The stake will pay x under 100, y under 200 and z under 300. Determine the optimal x, y, and z assuming cousin's certainty equivalent must be at least zero. Explain the qualitative features of your answer. Oh yes, the cousin's utility function is -exp(-0.02$ Ralph's Lottery RalphRisk 0.01 Prob.
