You often hear about the trade-off between risk and reward. Is this trade-off part of decision making under uncertainty when the decision maker uses theEMV criterion? For example, how does this work in investment decisions?
You are entrusted with deciding whether to make or buy software. The make decision has a setup cost of $15,000 and a monthly maintenance cost of $1,200. A vendor will sell the software for an initial cost of $11,400 and a monthly cost of $3,000. For how many months must the company use this software to support a make decision?

- You are the owner of four Taco Bell restaurant locations. You have a business loan with Citizens Bank taken out 60 days ago that is due in 90 days. The amount of the loan is $70,000, and the rate is 9.5% using ordinary interest. You currently have some excess cash: $25,000. Due to situations beyond your control, you, as the owner, must make an immediate business decision now to pursue only one of these two choices:1) sending all of the $25,000 to Citizens Bank as a partial payment on your loan, or2) using the $25,000 to purchase serving supplies such as food containers, cups, and plastic dinnerware for your inventory. This is the last day to take advantage of the opportunity to save some money due to a special discount price that is "10% off" the normal cost of $25,000 for these items. Consider these calculations: (a) How much interest (in $) will you save on this loan if you make the partial payment and don't purchase the additional serving supplies?

Fairnessarrow_forwardYou are planning to rent a car for a one-week vacation. You have the option of buying an insurance that costs $80 dollars for a week. If you do not purchase insurance, you would be personally liable for any damages. You anticipate that a minor collision will cost $2,000, whereas a major accident might cost $16,000 in repairs. Develop a payoff table for this situation. What decision should you make using each strategy? Aggressive (Optimistic) Conservative (Pessimistic) Opportunity Loss You have recently read in a magazine that that the probability of a major accident is 0.05% and that the probability of a minor collision is 0.18%.

- Discuss the differences between decision making under certainty, under risk, and under uncertainty.arrow_forwardYou've heard the expression "no pain, no gain"? In the investment world, the comparable phrase would be "no risk, no reward." How you feel about risking your money will drive many of your investment decisions. The risk-comfort scale extends from very conservative (you don't want to risk losing a penny regardless of how little your money ears) to very aggressive (you're willing to risk much of your money for the possibility that it will grow tremendously). As you might guess, most investors' tolerance for risk falls somewhere in between. If you're unsure of what your level of risk tolerance is, this quiz should help. 8. You want to take someone out for a special dinner in a city that's new to you. How do you pick a place? (a) read restaurant reviews in the local newspaper, (b) ask co-workers if they know of a suitable place, (c) call the only other person you know in this city, who eats out a lot but only recently moved there, (d) visit the city sometime before your dinner to check out…arrow_forwardThe more information a manager has, the less risk there is that a decision will be incorrect.; True or Falsearrow_forward
