Scenario: You Are Deciding Among Three Investments
Scenario You Are Deciding Among Three Investments As You Do For Case
Scenario: You are deciding among three investments, as you do for Case 4. You have heard of an expert who has a highly reliable “track record” in the correct identification of favorable vs. unfavorable market conditions. You are now considering whether to consult this “expert.” Therefore, you need to determine whether it would be worth paying the expert’s fee to get his prediction. You recognize that you need to do further analysis to determine the value of the information that the expert might provide. In order to simplify the analysis, you have decided to look at two possible outcomes for each alternative (instead of three). You are interested in whether the market will be Favorable or Unfavorable, so you have collapsed the Medium and Low outcomes. Here are the three alternatives with their respective payoffs and probabilities.

Introduction
Investment decision-making involves assessing potential gains, losses, and the value of additional information to optimize financial outcomes. When faced with multiple investment options, investors often consider consulting experts to refine predictions about market conditions. Evaluating whether the cost of expert advice is justified hinges on understanding the value of perfect or imperfect information about future market states. This paper examines the decision scenario where an investor must choose among three investments, considering whether to leverage an expert’s reliable predictions to improve decision-making under uncertainty. The analysis aims to determine whether paying for expert advice offers a positive expected value that outweighs its costs.
Scenario Overview and Context
The scenario involves an investor deliberating among three investment alternatives, each with distinct payoffs and associated probabilities based on market conditions. The market conditions are simplified into two states: Favorable and Unfavorable, collapsing medium and low outcomes into unfavorable. The investor's core question is whether to consult a highly reliable market prediction expert, considering the cost of their services and the potential benefits of improved decision accuracy. Such analysis hinges on the concept of the value of information, which quantifies how much better the investment decision can be made with additional information about future states of the market.
Decision Alternatives and Payoff Structure
The three investment options are characterized by their payoffs under different market conditions. For simplicity, the expected payoffs are analyzed under the two-state model, and probabilities of favorable and unfavorable conditions are specified. The goal is to compare the expected outcomes with and without consulting the expert, considering the expert’s accuracy and cost, to identify the optimal decision.
Expected Value and Value of Perfect Information
Prior to considering expert input, the decision-maker evaluates the expected value of each investment based on the probabilities of market states. The value of perfect information (VPI) quantifies how much better the outcome could be if the investor knew the true market condition beforehand. This measure sets an upper bound on the worth of obtaining expert predictions. If the expected value of acting with expert advice exceeds the cost of obtaining it, then consulting the expert would be economically justified.
Analysis Methodology
The analysis involves calculating expected payoffs for each investment option both with and without expert advice. The expected outcomes are weighted averages based on the predicted probabilities of market conditions and the expert's track record. The expected value with expert advice also incorporates the probability that the expert’s prediction is correct, which influences the decision to follow the expert’s recommendation.
Application of Decision Theory
Applying decision theory principles, such as decision trees or Bayesian analysis, enables quantification of the expected benefits of expert consultation. The model considers the initial probabilities, the likelihood of correct predictions, and the payoffs associated with each scenario. This approach helps determine whether the expected value of perfect information or the expected value with imperfect (credible) advice justifies the expense of consulting the expert.
Conclusion
Deciding whether to consult a market expert involves balancing the cost of advice against the potential for improved decision-making and higher investment payoffs. By quantifying the value of information, investors can make informed choices about investing in expert predictions. In the scenario analyzed, if the expected increase in payoff derived from expert insights exceeds the consultation fee, it is financially advantageous to seek the expert’s opinion. Conversely, if the value of additional information does not justify the cost, the investor should proceed without expert consultation. Ultimately, applying decision analysis tools allows for rational decision-making that maximizes expected returns under uncertainty.
