###### Question details

**Problem 1B:**

You want to invest money in real estate. The following table summarizes the payoffs of the investment in good or bad economic situations.

States of nature | ||

Actions | Good | Poor |

Apartment building | $ 50,000 | $ 30,000 |

Office building | $ 100,000 | - $40,000 |

Warehouse | $ 30,000 | $ 10,000 |

You estimate that the probabilities of having good or bad economic situations are 70% and 30%, respectively.

- Find the optimal action based on the expected monetary value (EMV) criterion using your prior probability estimates.
- Find the optimal action based on the expected opportunity loss (EOL) criterion using your prior probability estimates.
- Determine the expected value of perfect information (EVPI).

You decide to consult a financial advisor about his opinion of "for" or "against" the investment. In the past, the advisor's opinion has been "for" in 85% of the cases where the economic situation was "good", and the opinion has been "against" in 90% of the cases where the economic situation was "poor".

4. Draw the decision tree.

5. Under "for" recommendation, determine the posterior probabilities for "good" and "poor" economic situations, and find the optimal action based on the EMV using the posterior probabilities.

6. Under "against" recommendation, determine the posterior probabilities for "good" and "poor" economic situations, and find the optimal action based on the EMV using the posterior probabilities.

7. Determine the expected value of sampling information (EVSI) and the efficiency of sampling information.
