We should therefore decide to supply 70 salads a day. tomorrow then there is uncertainty but no risk as there is no monetary loss. Download all ACCA course notes, track your progress, option to buy premium content and subscribe to eNewsletters and recaps. The more variable these outcomes are the greater the risk. It will not tell the business which is thebetter project. Random numbers are then assigned to each variable in aproportion in accordance with the underlying probability distribution.For example, if the most likely outcomes are thought to have a 50%probability, optimistic outcomes a 30% probability and pessimisticoutcomes a 20% probability, random numbers, representing thoseattributes, can be assigned to costs and revenues in those proportions. The more variable these outcomes are the greater the risk. Test your understanding 3 - Applying maximin. For 60 salads,the maximum regret is $160, and $240 for 70 salads. Thus the external purchase price only needs to increaseby $1 per unit (or $1/ $6 = 17%). This is because a risk neutral investor neither seeks risk or avoids it; he is happy to accept an average outcome. It uses simulation to generate a distribution of profits for eachproject. Managing risk is easier because you can identify risks and develop a response plan. Share Related Material. is on that eliminates all risk in a position. The probabilities used are usually very subjective. Field research (primary research). If the geologist charges $7,000, wouldyou use her services? describe generally available research techniques to reduce uncertainty, e.g. A key event. Comparing contribution figures, the product should be bought in and re-badged: Step 2: Calculate the sensitivity (to the external purchase price). Lecture notes in Risk & Uncertainty. Taking two quick stops at Webster’s, 2 we find the following:. Risks can be measured and quantified while uncertainty cannot. portfolio. Depth interviewing – undertaken at length by a trained person who is able to appreciate conscious and unconscious associations and motivations and their significance. A perfect hedge In risk you can predict the possibility of a future outcome, while in uncertainty you cannot. It obtains existing data by studying published and other available sources of information. small loss in the form of a payment to the insurer in exchange for the insurer’s promise to This has a lower risk but also a loweraverage return. Typically, it involves posing 'what-if'questions. sometimes cause the transactions to go awry. Disclosure can be a tool for companies to communicate how they are navigating through such uncertainty. It is often used in capital investment appraisal. For example, if the demand is 40 salads, we will make a maximumprofit of $80 if they all sell. Choose the best option at each decision point. Answer - University advertising decision tree. Against this backdrop of uncertainty, detailed and useful disclosure may be a challenge for boards. Such information will be both commercial and technical, for example, the level of sales of competitors' products recorded by the Business Monitor or Census of Production; the product range offered by existing or potential competitors; the number of outlets forming the distribution network for a company's products; the structure of that network by size, location and relation to the end user; and the best overseas markets for a company. If there is oil, the probability that she will say there aregood prospects is 95%. In ISO 9000:2015, within the definition of risk a note expands on the term uncertainty. Non-Insurable Risk 4. The maximax rule involves selecting the alternative that maximises the maximum pay-off achievable. A manager is considering a make v buy decision based on the following estimates: You are required to assess the sensitivity of the decision to the external purchase price. Assess the use of simulation for a chain of betting shops. odds of being killed on a single airline flight are 1/29 million Estimated probability (uncertainty) – Most common, demands judgment All probabilities should add up to '1'. There is no complicated theory to understand. You can assign a probability to risks events, while with uncertainty, you can’t. Risk implies a chance for some unfavourable outcome to occur. Risks can be managed while uncertainty is uncontrollable. If the external purchase price rose bymore than 17% the original decision would be reversed. assign probabilities to each of these possible outcomes, risk is said to exist. In uncertainty, the outcome of any event is entirely Decision-making under Certainty: . Therefore, the contributionper salad is $2. Factors to consider when using desk research. This sort of information can also be collected in retail environments at the point of sale, for example, through the use of loyalty cards. It is useful for a risk-neutral decision maker. 2. The EV gives no indication of the dispersion of possible outcomes about the EV, i.e. Risk and Uncertainty The concept of (fundamental) uncertainty was introduced in economics by Keynes (1921, 1936 and 1937) and Knight (1921). If wedecide to supply 50 salads, the maximum regret is $80. Here C would be chosen with a maximum possible gain of 100. risk and uncertainty. 978 Simona-Valeria Toma et al. (a)You have the mineral rights to a piece ofland that you believe may have oil underground. 4 that there is a 50% chance of drawing a red ball. If conditions are poor it is expected that the programme will attract 40 students without advertising. Their cost and logistical complexity is frequently cited as a barrier, especially for smaller companies. In summary, risk refers to the potential variability of outcomes from a decision. Subject: Managerial Economics. Moral hazard- Occurs when someone increases their exposure to risk when insured, especially when Well, this article might help you in understanding the difference between risk and uncertainty, take a read. The question is as follows : how much would it be worth paying for such imperfect information, given that we are aware of how right or wrong it is likely to be? 8763 reads; Except where stated, resources on this page are available under a Creative Commons by-nc licence. Upon completion of this chapter you will be able to: Risk is the variability of possible returns. The value of information (either perfect or imperfect) may be calculated as follows: Expected Profit (Outcome) WITH the information LESS Expected Profit (Outcome) WITHOUT the information, Test your understanding 4 - Geoffrey Ramsbottom. the other party. If we employ the geologist, the probabilities of her possibleassessments can be tabulated as follows (assume 1,000 drills in total): A decision tree can be drawn to calculate the expected value of profits if a geologist is employed: EV(A) = (41.30% x $200,000) - $10,000 drilling costs = $72,600.The decision at 'C' should be to drill, as this generates higherbenefits than not drilling. In other words, it is obtained by multiplyingthe value of each possible outcome (x), by the probability of thatoutcome (p), and summing the results. Home » Learning & Teaching » Links to resources » Sub-disciplines » Risk and Uncertainty. It provides information on the basis of which decisions can be made but it does not point to the correct decision directly. Clearly, risk permeates most aspects of corporate decision-making (and life in general), and few can … There is a 60% chance that economic conditions will be poor. The difference, or 'regret' between thatnil profit and the maximum of $80 achievable for that row is $80. They felt a distinction should be made between risk and uncertainty. Best estimates for variables are made and a decision arrived at. Uncertainty is a lack of complete certainty. The maximin rule involves selecting the alternative that maximisesthe minimum pay-off achievable. Simulation is a modelling technique that shows the effect of more than one variable changing at the same time. rolling a dice, roulette wheel Statistical probability: Observed frequencies used to predict outcomes. For example, about the likely responses of customers to newproducts, new advertising campaigns and price changes. Insurance: Is a form of risk management primarily used to hedge against the risk of a contingent Accountants (IESBA), published by the International Federation of Accountants (IFAC) in December 2012 and is used with permission of IFAC. We can now construct a pay-off table as follows: When probabilities are not available, there are still tools available for incorporating uncertainty into decision making. Prof. Dr. Svetlozar Rachev (University of Karlsruhe) Lecture 6: Risk and uncertainty 2008 4 / 100 Step 1: Draw the tree from left to right, showing appropriate decisions and events / outcomes. Conversely, many companies, especially blue-chips and public services, can often be seen to produce reams of data for no apparent reason, or because 'we always have done'. A circle is used to represent a chance point. Kaplan Financial Limited. Word association testing – on being given a word by the interviewer, the first word that comes into the mind of the person being tested is noted. Lecture notes in Risk & Uncertainty. Nevertheless, there is evidence that people can learn from warnings and risk information, such On-line focus groups are becoming more popular and help to address this issue. Quota sampling– where samples are designed to be representative with respect to pre-selected criteria. Simulation would be particularly useful on an operational level foranalysing the possible implications of a single event, such as a majorhorse race or football match: Simulation could also be used for wider strategic analysis such asfor assessing the possibility and implications of stricter anti-gamblinglegislation. Surveying by post– the mail shot method. The branches coming away from a circle with have probabilities attached to them. material prices will change independently of other variables. Using the information from the previous TYU apply the maximin rule to decide which product should be made. For both options, a circle is used to represent a chance point - a poor economic environment, or a good economic environment. The following estimatesare made: Since the expected value shows the long run average outcome of adecision which is repeated time and time again, it is a useful decisionrule for a risk neutral decision maker. This Product includes content from the International Auditing and Assurance Standards Board (IAASB) and the International Ethics Standards Board for. A new ordering system is being considered, whereby customers mustorder their salad online the day before. Internal company data is perhaps the most neglected source of marketing information. How much is this new system worth to Mr Ramsbottom? Therefore, our analysis must extend to deal with imperfect information. ⇒ Risk is qualified as an asymmetric phenomenon in the sense that it is related to loss only. Author: Saral Notes. 8763 reads; Except where stated, resources on this page are available under a Creative Commons by-nc licence. Risk: there are a number of possible outcomes and the probability of each outcome is known. Using maximin, a pessimist would consider the poorest possible outcome for each product and would ensure that the maximum pay-off is achieved if the worst result were to happen. Games of chance were common in those times and the players of those games must have recognized that there was an order to the uncertainty.1 As Peter Bernstein notes in his splendid book on the history of risk, it is a mystery why the Greeks, with their Lecture Notes: General Insurance Lecture 8: Risk and uncertainty in pricing and reinsurance By Omari C.O 1 Risk and uncertainty in pricing and reinsurance 1.1 Introduction Insurance contracts transfer elements of risk and uncertainty from customers to insurers. A powerful computer is then used to repeat the decision many timesand give management a view of the likely range and level of outcomes.Depending on the management's attitude to risk, a more informed decisioncan be taken. The number of students starting the programme is dependent on economic conditions: If the programme is advertised and economic conditions are poor,there is a 65% chance that the advertising will stimulate further demandand student numbers will increase to 50. Probability Analysis 5. Project B has a higher average profit but is also more risky (more variability of possible profits). Test your understanding 2 - Applying maximax. Examination. Chapter 4 – Pricing Theory and Practices. have or vice versa. The formula for the expected value is EV = Σpx. the risk. When the level of risk and the attitudes toward risk taking are known, the effects of uncertainty can be directly reflected in the basic valuation model of the firm. F.H., 1921, Risk, Uncertainty and Profit, New York Hart, Schaffner and Marx. Diversification: Is a risk management technique that mixes a wide variety of investments within a rolling a dice, roulette wheel Statistical probability: Observed frequencies used to predict outcomes. Because the fluctuations of a single security have less impact on a diverse portfolio, Knight argues that the second individual is exposed to risk but that the first suffers from ignorance. There is only a 10%chance that you will strike oil if you drill, but the profit is$200,000. If we decide to supply 60 salads, the minimum pay-off is ($80). Why pandemics are highly uncertain and should be treated as such. Risk and Uncertainty. Almost all economic transactions involve Risk, Uncertainty, and the Precautionary Principle 2. Market intelligence is information about a company's present or possible future markets. Some common symbols can be used: a square is used to represent a decision point (i.e. The decision maker therefore chooses the outcome which isguaranteed to minimise his losses. Risks are events or conditions that may occur, and whose occurrence, if it does take place, has a A manager employingthe minimax regret criterion would want to minimise that maximum regret,and therefore supply 40 salads only. The main disadvantage of quota sampling is that samples may still be biased for non-selected criteria. The use of research techniques to reduce uncertainty. She can tellyou whether the prospects are good or poor, but she is not a perfectpredictor. In short, risk may be defined as the degree of uncertainty about an income. The decision at 'D' should be not to drill. An entity which provides insurance is In summary it suggest when faced with missing or imperfect information about an event, probability, or outcome, we are uncertain.Continue Reading Management Notes – On – Risk And Uncertainty – For W.B.C.S. The Value of Perfect and Imperfect Information. The certainty equivalent method converts expected risky profit streams to their certain sum equivalents to eliminate value differences that result from different risk levels. According to the pay-off table from Illustration 5, the Expected Value of Profits if 40 salads are supplied can be calculated as (0.10 x $80) + (0.20 x $80) + (0.40 x $80) + (0.30 x $80) = $80. She can tellyou whether the prospects are good or poor, but she is not a perfectpredictor. Risk implies future uncertainty about deviation from expected earnings or expected outcome. For example, someone with insurance against automobile theft may be less vigilant Copyright © 2020 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01, Coursebook Economics of Information 2019 20. There is a 40% chance that economic conditions will be good. Author: Saral Notes. Draw a decision tree and calculate the value of imperfectinformation for this geologist. For example, the same oil company may dig for oil in a previouslyunexplored area. Risk & Uncertainty. Some of the more common techniques in motivational research are: Measurement research – the objective here is to build on the motivation research by trying to quantify the issues involved. the insurance company that you smoke and drink a lot? It can often eliminate the need for extensive field work. It is only of any real value, however, if theunderlying probability distribution can be estimated with some degreeof confidence. Distinction between risk and uncertainty.  Risk can be managed while uncertainty is uncontrollable. Unfortunately the sample becomes self-selecting and so may be biased. It is concerned with such factors as gross national product (GNP), investment, expenditure, population, employment, productivity and trade. In uncertainty, the outcome of any event is entirely unknown, and it cannot be measured or guesses; you don’t have background information on the event. Risk and uncertainty in economics notes - Unser Gewinner . The random numbers generated give 5 possibleoutcomes in our example: A business is choosing between two projects, project A and projectB. Uncertainty Uncertainty is a situation regarding a variable in which neither its probability distribution nor its mode of occurrence is known. This includes: The small sample size means that results may not be representative. Hi John, the concept has been well explained in the lecture, the assumption is the spread is a normal distribution and hence the graph is symmetrical and hence there is a 50% chance of the return being higher or lower than the average return. The film whichhas been code named CA45 is a thriller based on a novel by a wellrespected author. It’s a risk management technique used to reduce any substantial losses or gains suffered free samples in a shop. In case of risk all possible future events or consequences of an action or decision are known. Risk is thus closer to probability where you know what the chances of an outcome are. The MP Organisation is an independent film production company. Market research findings, for example, are likely to bereasonably accurate - but they can still be wrong. A square is used to represent a decision point (i.e. Uncertainty refers to the situation where probabilities cannot be assigned to expected outcomes. COVID-19 - Going concern, risk and viability 3 Quick Read The COVID-19 crisis and responses to it are creating unprecedented global uncertainty. If this exceeds $10,000, the geologist would be worth employing as long as the benefit of employing her exceeds her charge of $7,000. Created at 5/24/2012 4:39 PM  by System Account, (GMT) Greenwich Mean Time : Dublin, Edinburgh, Lisbon, London, Last modified at 5/25/2012 12:54 PM  by System Account. ‘Regret' in this context is defined as the opportunity loss through havingmade the wrong decision. It is the process ofunderstanding and managing the risks that an organisation is inevitablysubject to.  Risks can be measured and quantified while uncertainty cannot. By using this technique it is possible to establish which estimates(variables) are more critical than others in affecting a decision. EV(E) = 0.23 x $72,600 = $16,698. The EV may not correspond to any of the actual possible outcomes. to get life insurance. ADVERTISEMENTS: Uncertainty, Risk and Probability Analysis in Economic Activity! This created an imbalance of power and in transactions which can It only identifies how far a variable needs to change; it does not look at the probability of such a change. Synonyms for uncertainty include: unpredictable, unreliability, riskiness, doubt, indecision, unsureness, misgiving, apprehension, tentativeness, and doubtfulness. who doesn’t, it could set rates differently for each group and there would be no adverse selection. Sensitivity analysis takes each uncertain factor in turn, andcalculates the change that would be necessary in that factor before theoriginal decision is reversed. Such samples are morelikely to be representative, making predictions more reliable. University: Tribhuvan University (TU) Course: Masters of Business Studies (MBS) Semester / Year: 1. party insulated from risk may behave differently from the way it would behave if it were fully It provides an organisation with a picture of past and future trends in the environment and with an indication of the company's position in the economy as a whole. Individuals may feel under pressure to agree with other members or to give a 'right' answer. Uncertainty is a lack of complete certainty. Risk the risks surrounding a business or investment. This normally happens when the seller of a good or service has greater knowledge claims by limiting coverage or raising premiums. determine the amount, called the premium, to be charged for a certain amount of insurance This helps to model what is essentially a one-off decision usingmany possible repetitions. The financial outcomes and probabilities are shown separately, andthe decision tree is ‘rolled back' by calculating expected values andmakingdecisions. (b) We will calculate the Expected Value of profits if we employ the geologist. Using maximax, which product would be chosen? Contents: 1. A complex problem is brokendown into smaller, easier to handle sections. An event without uncertainty in the outcome is not a risk, and uncertainty without an event produces no outcome, so again there is no risk. where a choice between different courses of action must be taken. One could say the penguin's uncertainty about the outcome of his next step is the risk, but here you need both the event of him taking a step, and uncertainty in the event outcome to make up the risk. Risk, Uncertainty, and the Precautionary Principle 2. The time and costs involved in their construction can be more than is gained from the improved decisions. This approach would be suitable for an optimist, or 'risk-seeking'investor, who seeks to achieve the best results if the best happens. It cannot be used for individual units, selling prices, variable cost per unit, etc. – ex. Many biases in risk assessment and regulation, such as the conservatism bias in risk assessment and the stringent regulation of synthetic chemicals, reflect a form of ambiguity aver-sion. With this new system MrRamsbottom will know for certain the daily demand 24 hours in advance.He can adjust production levels on a daily basis. After reading this article you will learn about Decision-Making under Certainty, Risk and Uncertainty. There are three main types of information that can be collected by desk research: Motivational research – the objective is to understand factors that influence why consumers do or do not buy particular products. Content: Risk Vs Uncertainty Label the tree and relevant cash inflows/outflows and probabilities associated with outcomes : (a)   Calculate an Expected Value at each outcome point. Perfect information The forecast of the future outcome isalways a correct prediction. For example, what is the chance of the selling price falling by more than 5%? Home » Learning & Teaching » Links to resources » Sub-disciplines » Risk and Uncertainty. It costs $10,000 to drill. unknown, and it cannot be measured or guesses; you don’t have background information on the A decision tree is a diagrammatic representation of amulti-decision problem, where all possible courses of action arerepresented, and every possible outcome of each course of action isshown. Conversely, uncertainty refers to a condition where you are not sure about the future outcomes. The maximum possible change is often expressed as a percentage.This formula only works for total cash flows. Possible outcomes are easy to identify (e.g. risk and uncertainty lecture 2 1. risk and uncertainty by syed muhammad ijaz, fca dated august 03, 2007 2. said to be risk free if the outcome is known with certainty. In fact, informationsources such as market research or industry experts are usually subjectto error. ... Notes are saved with you account but can also be exported as plain text, MS Word, PDF, Google Doc, or Evernote. Therefore, product A would be chosen resulting in a minimum pay-off of 20 compared to a minimum pay-off of 10 for products B and C. In many questions the decision makers receive a forecast of afuture outcome (for example a market research group may predict theforthcoming demand for a product). It is not a technique for making a decision, only for obtaining more information about the possible outcomes. Copyright 2020. The insurance transaction involves the insured assuming a guaranteed and known relatively ACC3023S MANAGEMENT ACCOUNTING II RISK AND UNCERTAINTY 6 Lecture Example 1: Basic Expected value Product A profit probability distribution Notes (A) (B) (C) Possible Outcome Estimated probability Weighted amount R Profits of R6 000 0.10 Profits of R7 000 0.20 Profits of R8 000 0.40 Profits of R9 000 0.20 Profits of R10 000 0.10 1.00 This forecast may turn out to becorrect or incorrect. (b)Before you drill, you may consult ageologist who can assess the promise of the piece of land. In summary it suggest when faced with missing or imperfect information about an event, probability, or outcome, we are uncertain. Observation– e.g. We will calculate the Expected Value of profits if we employ the geologist. Risk management is important in a business. It’s a strategy designed to minimise exposure to an unwanted The maintypes of measurement are: Random sampling– where each person in the targetpopulation has an equal chance of being selected. An investment decision is In the process, he loses out on theopportunity of making big profits. If 40 salads will be required on 25 days of a 250-day year, the probability that demand = 40 salads is : Likewise, P(Demand of 50) = 0 .20; P(Demand of 60 = 0.4) and P(Demand of 70 = 0.30). Risk and Uncertainty 1. To fight adverse selection, insurance companies reduce exposure to large For example, based on past experience of digging for oil in aparticular area, an oil company may estimate that they have a 60% chanceof finding oil and a 40% chance of not finding oil. Adverse selection is the tendency of those in dangerous jobs or high- risk lifestyle investment. Takes uncertainty into account by considering the probability of each possible outcome and using this information to calculate an expected value. If however we supply 50 salads but only 40 are sold, our profits will amount to 40 x $2 - (10 unsold salads x $8 unit cost) = 0. In addition to the research techniques discussed, the following methods can be used to address risk or uncertainty. Triad testing – where people are asked which out of a given three items they prefer. The company knows that it is possible for them toeither find or not find oil but it does not know the probabilities ofeach of these outcomes. The following are a few differences between risk and uncertainty: 1. Uncertainty: there are a number of possible outcomes but the probability of each outcome is not known. If the minimax regret rule is applied to decide how many saladsshould be made each day, we need to calculate the 'regrets'. a person takes more risks because someone else bears the cost of those risks. In uncertainty, you completely lack the background Expected costs (advertising, promotion and marketing) have alsobeen estimated as follows: there is a 20% chance they will reachapproximately $248,000; 60% chance they may get to $260,000 and 20 %chance of totalling $272,000. Imperfect information is not as valuable as perfect information. This is the expected value ofprofits if a geologist is employed and exceeds the EV of profits if sheis not employed. If we decide to supply 50 salads, the minimum pay-off is $0. The model identifies key variables in a decision : costs andrevenues, say. Now let's look at the different values of profit or losses depending on how many salads are supplied and sold. Working from top to bottom, we can calculate the EVs as follows: EV (Outcome Point A) = (35% x $100,000) + (65% x $150,000) = $132,500, EV (Outcome Point B) = (0% x $0) + (25% x $25,000) = $6,250, EV (Outcome Point C) = (60% x $115,000) + (40% x $15,000) = $75,000, EV (Outcome Point D) = (60% x $132,500) + (40% x $6,250) = $82,000. Moral hazard arises because an individual does not bear the full consequences For example, if the target population is 55% women and 45% men, then a sample of 200 people could be structured so 110 women and 90 men are asked, rather than simply asking 200 people and leaving it up to chance whether or not the gender mix is typical. Thus it is clear then that though both ‘risk and uncertainty’ talk about future losses or hazards, while risk can be quantified and measured; there is no known way of ascertaining uncertainty.
