A group of investors wants to open up a jewelry store in a new shopping center. The investors are trying to decide whether to stock the store with expensive jewelry, medium-priced jewelry, or inexpensive jewelry. The probability of their choice depends upon the economic conditions. The payoff table below gives the anticipated monthly profits (in $) for different states of the economy. The probability of prosperity is 0.4. States of Nature Decision Alternative Prosperity Recession Expensive 19,000 -4,000 Medium 9,000 3,000 Inexpensive 6,000 12,000 (a) Determine the expected value (in $) of each alternative. EV(Expensive) = $ EV(Medium) = $ EV(Inexpensive) = $ Indicate which decision alternative is the best. O Expensive O Medium O Inexpensive(b) Determine the expected value with perfect information (in $) about the states of nature. $ (c) Determine the expected value of perfect information (in $)
