Introduction Theory was formulated in 1979 by two Israel psychologists Kahneman and Tversky. The theory was developed in order to create an alternative for the Expected utility theory that was used as the base for decision making under risk for number of years. This was done by identifying the flaws with in the Expected utility theory and addressing those using experimental economics. The theory has two parts editing phase and the evaluation phase. And the striking difference in this theory to EUT would be the value function. This has two arguments addressed in it; they are (i) Reference point and (ii) Magnitude of change. The critique of PT will be done in two phases. Comparing PT to EUT and noting the advantages whiles the 2nd phase by identifying …show more content…
PT - the arguments against EUT When comparing with EUT in this paper author has critique in two stages; One PT says the individuals weigh all the outcomes that arises within prospects, Two the editing phase. These are affected by the expectation of the individual. (Starmer 2000). Certainty effect - When weighting is considered in PT argument goes as people tend to overweigh based on the certainty as oppose to its mentioned in EUT where probability is been used to assess the utility. By using Allais’ paradox (Maurice Allais 1953) authors have identified this. In EUT there substitution axiom has been violated based on PT survey. What it implies in below problem 1 when the wining is significant they tend to go for the option which has a higher probability even though it has a low return. And in problem 2 when the probability is microscopic then they opt in to the option which has a higher gain yet risk is also …show more content…
As well as both the theories as disregard the process of group decision making. The process of an individual decision making appose to a group is very different. There are many factors in effect e: g size, group composite and the overall personality. (Chernyshenko et al 2003). Another characteristic that these two show case is the linearity of the theories. One of the noticeable flaws in PT is that this theory has not considered the sunk cost involve. (Garland and new port 1991. Heath 1995, Carmichaek 2003, Highhouse and yuce 1996. Parayre 1995 schaubroeck and Davis 1994). The sunk cost is very much valuable in the decision making process even though the historical practice is to ignore it. Example for this can say a college student in his 3rd year would consider dropping out and exploring other possibilities in a theoretical world he should not consider the tuition fee he paid for the past 3 years, but in reality the student will consider the cost that if he continues to stay on oppose to the cost that he will render if he takes the 2nd option. And he will also consider the value after completing the 4 years oppose to value he will get at the moment in the labor

The loss aversion principle was first validated by Daniel Kahneman and Amos Tversky (1979) to explain for the outcome that experimental subjects required a unique over expected value to receive a wager proposing an even casual of a gain or loss (“the risky bet premium”). An individual is loss averse if she or he distastes symmetric 50-50 bets and, furthermore, the aversiveness to such bets increases with the absolute size of the stakes. Loss-Aversion theory states that people's observations of gain and loss are lopsided. Loss aversion denotes that one who loses $2,000 will lose more yearning than another person will gain contentment from a windfall of $2,000. In marketing, rebates tries and the use of trial periods to take leverage of the
Group think According to Janis, who coined the term; groupthink “occurs when a group makes faulty decisions because group pressures lead to a deterioration of mental efficiency, reality testing, and moral judgment” (1972, p. 9) further group think often leads to a decrease in the mental efficacy perception of reality and moral judgement, as personages find themselves in a group system that seeks high cohesion and unanimity which delimits the motivation of the individual to realistically appraise alternate courses of action (Janis, 1972). A common trait of a collective experiencing this phenomenon, is an inclination to take irrational decision making in addition to members of the group being similar in background and further being insulated from external insight. Comparably the singularity of groupthink is present in the film 12 Angry Men, and appears anecdotally, early on the film, present in the expected unanimous vote of ‘guilty,’ that will send the defendant to the electric chair. Invulnerability Literature surrounding the concept of group think is greatly rooted in the writings of Janis.
Psychologist Irving Janis explained some alarmingly bad decisions made by governments and businesses coined the term "groupthink”, which he called "fiascoes.” He was particularly drawn to situations where group pressure seemed to result in a fundamental failure to think. Therefore, Janis further analyzed that it is a quick and easy way to refer to a mode of thinking people engage in when they are deeply involved in a cohesive in-group, when the members ' striving for unanimity override their motivation to realistically appraise alternative courses of action. According to Janis, groupthink is referred as the psychological drive for consensus at any cost that suppresses disagreement and prevents the appraisal of alternatives in cohesive decision-making groups.

What are the consequences of a particular choice? How may changes in decision-making environment affect choices?
Some concerns Ron my endure with new customers are: the customer will not want to buy his company’s products (Johnston & Marshall, 2009). The customer does not trust Mid-Town’s products (Johnston & Marshall, 2009). The customer may not like or trust Ron (Johnston & Marshall, 2009). Last, the customer thinks the prices are too high (Johnston & Marshall, 2009). Many customers are concerned about buying products from new vendors, moreover, they do not know the brand of the products and if they would hold up to expectations (Lurie, 2004).
Jenness (1932) found that when experiment participants carried out the task in a group, they reported estimates of roughly same value even though they had previously quoted different estimates as individuals. Jenness’ study revealed the impact of majority influence, and established a direct correlation between a group influence on an individual’s behaviour and beliefs especially when participants are uncertain about the actual number of beans in the jar. Another classical study on conformity was based on finding out how social norms are developed in social groups and how the influences of these norms when developed impact on an individual’s behaviour. The Autokinetic phenomenon study of Sherif (1937) according to Baron et al. (2008, p.277), illustrated vividly the impact of private acceptance of social influence.
DISCOUNTED UTILITY MODEL- Constant rate discounted utility models are commonly used to represent individual inter temporal preference in health care program evaluation. The mainly questions is of what rate of discount is used and the little attention has been paid to the appropriateness of the constant rate of discounted utility model. In discounted utility model, the utility of consumption is evaluated afresh in each time period. The discounted utility model is a factor that dominant model of inter temporal choice.
All decision making involves elements of risk and reward. Every decision there will be risk; it depends on how an individual, group or organisation sees it. Though bureaucracy and rational decision making model is found in Kmart and Wal-Mart, there are still other decision making model been used. Kmart focus on profit and trying to be the best while Wal-Mart focuses on increasing profits by believing its employees and
In using the theory of preference utilitarianism, making decisions is much simpler. One does
Therefore, the expected utility theory can explain the situations of certain individuals, in this case Anthony’s and the risk aversion; however, it cannot explain the reasoning of others due to the lack of a reference point in his theory. Kahneman concludes this chapter explaining why this theory survived for so long with its evident flaws. He believes that since it was already accepted and used, people got blind and could not notice those errors. Deliberating is hard and we tend to avoid

Also considered with cost-benefit analysis, the issue of “standing” can bias decision if other parties are not considered in calculation and affect financing. Cost-benefit analysis also attempts to calculate a “with or without” situation regarding a program and its effects in relation to either decision. This measures the values associated with program
