Prospect theory is a descriptive model concerning the issue of decision making under risk. The theory stated that people tend to made decision by examining the potential gain and loss comparing to reference point and exhibit certain kinds of heuristics and biases in this process such as certainty effect, reflection effect, probabilistic insurance and isolation effect. It also divided choice process into editing phases and the subsequent phase of evaluation, which were modified to framing and valuation phases in the later version (Kahneman and Tversky, 1979, Tversky and Kahneman, 1992). Some defect and weakness of prospect theory were spotted. The original version of prospect theory produces a violation of stochastic dominance(Machina, 1982), …show more content…
A crucial reason in favour of mental accounting and overconfidence is decision efficiency. Real-life investing scenario changes every moment Time-consuming and systematic thinking process seldom is allowed during the intense decision-making (Stewart Jr et al., 1999, Busenitz and Barney, 1997). Additionally, the ‘small world’ used by the economic theory, which only applied to strict condition, is not necessarily applicable in the practical investment decision. As the assumption in those analysis approach may not conform with real life well and for most of times, cognitive heuristics is more suitable for the uncertainty(Gigerenzer and Gaissmaier, 2011). However, there is also a few argument against them, for it may hinder people from examining their investment choice thoroughly. Research shows that they did not perceive themselves as risk taker, but in fact, they are more likely to take relatively low return alternatives as ‘opportunities’, indicating that they are risk-taking to a great extent(Palich and Ray Bagby, 1995). As a result of the illusion created by such factors, decision makers tend to be narrow-minded in composing strategies and unable to bring enough information into thought(Schwenk, 1988). It was demonstrated by several researches that decisions made by means of biases and heuristics impose …show more content…
One reason is that many successful investment ventures itself is the outcome of these ‘irrationality’. Risk-taking, which is inevitable in investment, may contribute to the investors’ better performance than others, while with the assistance of proper training, assessment accuracy can be increased(Palich and Ray Bagby, 1995). Also, if without precedent, most of the newly-invented value-maximising approaches or strategy of investment ought to be considered as crude and unthoughtful, but in reality, they are regarded as innovation(Busenitz and Barney, 1997). Furthermore, there are evidence shows that instead of being the hindrance of correct investment decision-making, those biases and heuristics are backed up by probabilistic information. Accurate statistical probability can be evaluated by our inductive reasoning mechanism with a relatively high possibility(Cosmides and Tooby,
The most vital part that has developed mankind is risk taking. Indeed, taking risks means that losses are almost inevitable. Yet, the very possibility of gaining from the result of risk taking means that risks are necessary. In fact, while taking risks may cause significant losses, it is the very possibility of gain that has made risk taking so essential to the development of humanity.
In this case, we do not need to think deeply about it by spending too much time on it. Even if there is something wrong, we can fix it. But, sometimes, it is so complicated and huge that our decision impacts not only us, but also others who are not really related to it. From the movie “Margin Call”, we can learn how we should make decisions considering others. The movie “Margin Call” begins with a scene where there is a round of layoffs happening at an investment banking firm and risk management specialist Eric Dale is one of them.
Good job on covering the information regarding Manhattan Bridge Capital, I have to be honest with you; I was not in possession of the facts in regards to the previously mention company. The company seems to be running smoothly and as a potential investor it good to know how they obtain funds and remain competitive in the investing world. After reviewing historical information, it became clear and concise that the loans are principally secured by collateral consisting of real estate and, generally, accompanied by personal guarantees from the principals of the businesses. Is it true that historical stock market returns are used to illustrate the relationship between irrational decision making and resulting investor underperformance using a

The evidence of many recent studies suggest that there are major differences between current theories of investment appraisal and the methods which firms actually use in evaluating long-term investment.
Although our decisions may be biased based on things presented to us beforehand, there is also a level of risk that plays into our decision-making strategies. Decisions that provide certainty seem to be chosen more often than those that only have probable outcomes (Kahneman & Tversky 1979). Prospect theory gives insight into our decision making process by saying that if we are more certain about probable outcomes, we are more likely to choose them (Kahneman & Tversky 1979). Within prospect theory are effects that give insight into risk taking and risk aversive behaviors. Risk aversion is a...
Asset allocation decisions made by an investor are considered more important than other decisions such as market timing or security selection. In the research provided by Hensel (1991), performance attribution is one of the main components when choosing the right assets in a portfolio. The impact of any investment decision can be measured by comparing its outcome with the outcome of some alternative decision. Furthermore, according to Hensel (1991), every investor has to incorporate the minimum-risk portfolio, which is a combination of securities or asset classes that reduces the uncertainty of future portfolio returns to a minimum.
The world we live in is overflowing with choices and chances. Every day, each and every human must make thousands of decisions. Some decisions may be rather simple to make, or not present a high chance for an unfavorable outcome. While one may decide the apple they picked up from the store is not very sweet, the cost lost on the apple is rather minimal and the consumer will most likely be presented with many more opportunities to pick a delicious apple. However, some choices are much more complicated. Decisions such as where to invest one’s money, or what physical challenges to endure, present very serious consequences. If the wrong decision is made, one could lose their financial security, or even their life.
Analyzing in terms of investment, if a private investor puts money into a company he has an expectation of both risk and return on the investment. Given a particular level of risk, the investment needs to be expected to have a particular level of return. For example, investment in a start-up needs to have the potential for a very high return, given the higher risk of failure, while investment in a large established business can be coupled with a lower expected return, given the lower risk of failure.
...s have shown that humans are risk averse, and they value loss more than gains from a bet, which means that wealth shows diminishing marginal utility.
The efficient market hypothesis has been one of the main topics of academic finance research. The efficient market hypotheses also know as the joint hypothesis problem, asserts that financial markets lack solid hard information in making decisions. Efficient market hypothesis claims it is impossible to beat the market because stock market efficiency causes existing share prices to always incorporate and reflect all relevant information . According to efficient market hypothesis stocks always trade at their fair value on stock exchanges, making it impossible for investors to either purchase undervalued stocks or sell stocks for inflated prices. As such, it should be impossible to outperform the overall market through expert stock selection or market timing, and that the only way an investor can possibly obtain higher returns is by purchasing riskier investments . In reality once cannot always achieve returns in excess of average market return on a risk-adjusted basis. They have been numerous arguments against the efficient market hypothesis. Some researches point out the fact financial theories are subjective, in other words they are ideas that try to explain how markets work and behave.
Accounting profit can serve as an alternative to intrinsic value. But Buffett states that “...we do not measure the economic significance or performance of Berkshire by its size; we measure by per-share progress.” Accounting reality was conservative, backward looking, and governed by GAAP (measures in terms of net profit), therefore Buffett rejects this alternative. According to the world’s most famous investor, investment decisions should be based on economic reality, not on accounting
Cohen and Felson (1979) proposed an innovative routine activity approach to analyze the crime rate trend. They summarized that only when the convergence in space and time of motivated offenders, suitable targets and the absence of capable guardians happened, crime could happen. They also mentioned that it is social structure that changed people’s legal activities of everyday life, and this in turn produced that convergence, which enriched the illegal activities. This means, even though the proportion of motivated offenders and suitable targets remain stable in the given area, the crime rate can still increase because of the increased likelihood of the convergence of those two at same time and location. In other words, the increasing dispersion
Therefore, to achieve this objective, managers have to make choices in decision-making, which is the process of selecting a course of action from two or more alternatives (Weihrich & Koontz; 1994, 199). A sound decision making requires extensive knowledge of economic theory and the tools of economic analysis, that are directly related in the process of decision-making. Since managerial economics is concerned with such economic theories and tools of analysis, it is very relevant to the managerial decision-making process.
Making decisions is an important part of our everyday life. Decisions define actions and lead to the achievement of goals. However, these depend on the effectiveness of the decision-making process. An effective decision is free from biases, uncertainties, and is deeply dependent on information and critical thinking. Poor decisions lead to the inability to achieve set objectives and could lead to losses, if finance is a factor. Therefore, it is important to contemplate about quality and ways to achieve it in decision-making, which is the focus of this paper. The purpose is to look into the needs of decision-making, including what one should do and what one should not do.
