# Kahneman And Tversky's Prospect Theory

Good Essays
Kahneman and Tversky developed the Prospect Theory to describe how people choose different choices that involve risk, knowing the probable outcomes. This demonstrates the way a person feels toward taking risks that involve positive outcomes is very different from the way a person feels toward risks that involve a negative outcome. The decision a person makes reflects on their judgement which can be heavy considering the conditions of uncertainty. For example, if people had a choice of: a) 100% chance receiving \$2,000, or b) Having an 80% chance of receiving \$3,000 and 20% receiving nothing, more than seventy-five percent of people would choose choice “b”. In reverse to that, if a person had a choice of: c) 100% chance of losing \$2,000, or d) …show more content…
In the single-feature model, a person bases their decision on a single characteristic. Its often a good method with a minor choice and wont make much of a difference. For example, if a person were at a store looking at all the choices of dog food, they may make their choice by just choosing the cheapest one. When there is a more at risk decision, the characteristic on one single item can increase the riskiness of their decision. With the additive model, its a better option to use for complex decision. A person creates a list of factors that are important to them, then goes back through and rates each factor on a scale of importance, such as 0 to 5. If one is extremely important to them, they rate it a 5. If one is not so important as the rest, they may rate it a 0 or 1. This strategy often helps point out the overall best choice for them by comparing the alternatives. Lastly with the elimination by aspects model, it involves looking at all the choices one feature at a time, starting with which is more important to them. If one choice fails to meet their criteria, they immediately mark it off the list of possible decisions. As their choices are narrowed down one at a time, they discover which is the best decision for them and what they want. All of these models relate to the Prospect Theory given that the way they decide determines on how much of an importance a decision it is to them and the amount of risks.

When these two types of decision makers appreciate their differences and work together in synergy they make a great team experience. Decision making from here is split up into five specific styles based on the individual identities within the group.

Smelling is less of a sense about gathering information about our surroundings and more of a defense mechanism. The defensive properties of the nose could be compensated for with relative ease. One would be able to mitigate the effect of the loss by using the other senses together. Most food that gets spoiled have visual signs as well as an odor. It would be very important to scan your food very carefully, as you would have very little of your sense of taste left, which is your last line of defense for faulty fuel going into your body.…

For Corning, pricing a security worth \$106.81 at \$100 may seem like an unfair deal. However, given Corning’s current financial distress, this may be the most reasonable method of financing. The risk still remains that the market will react poorly to this issuance. I believe \$100 is approximately the most Corning would be able to charge for these convertible securities and the \$6.81 discount should be viewed as a cost of financial distress. J.P. Morgan Has Proposed a Security That Will Benefit Investors and Address Corning’s…

Premise 4: If it is part of maximizing happiness for one to purchase food from the supermarket and avoiding the torturous practices of farm or factory raised meats as opposed to doing the torturing oneself then it is not morally wrong. The ethical theory of Act-Utilitarianism says that what makes an action right is that it maximizes happiness, those involved considered. This ethical theory supports my argument because the process of purchasing food, in this case farm raised meat, is a way of maximizing happiness for oneself and for those involved including family…

The simplest principle believes that when you have two or more options that can result in saving some people, you must perform the option with the higher probability of saving someone. The application of this principle lies in increasing your funds for future donating ability. The Sure-Thing Rescue Principle would rather save a certain number of people now, (because the probability of helping them is near one hundred percent) than wait for money to build up and help an uncertain number of people in the future. The probability of helping people goes down when you are waiting for money to build. Even if you are the top Wall Street stock broker, you could still make a mistake.…
