Chapter 1, Problem 1.32ACI
Guilt in decision making. The effect of guilt emotion on how a decision maker focuses on the problem was investigated in the Journal of Behavioral Decision Making (January 2007). A total of 171 volunteer students participated in the experiment, where each was randomly assigned to one of three emotional states (guilt, anger, or neutral) through a reading/writing task. Immediately after the task, the students were presented with a decision problem (e.g., whether or not to spend money on repairing a very old car). The researchers found that a higher proportion of students in the guilty-state group chose to repair the car than those in the neutral-state and anger-state groups.

Exercise 3.2 A three-man board, composed of A, B, and C, has held hearings on a
personnel case involving an officer of the company. This officer was scheduled for
promotion but, prior to final action on his promotion, he made a decision that cost the
company a good deal of money. The question is whether he should be (1) promoted
anyway, (2) denied the promotion, or (3) fired. The board has discussed the matter at
length and is unable to reach unanimous agreement. In the course of the discussion it
has become clear to all three of them that their separate opinions are as follows:
• A considers the officer to have been a victim of bad luck, not bad judgment, and
wants to go ahead and promote him but, failing that, would keep him rather than
fire him.
⚫ B considers the mistake serious enough to bar promotion altogether; he'd prefer
to keep the officer, denying promotion, but would rather fire than promote him.
⚫ C thinks the man ought to be fired but, in terms of personnel policy and…
Three researchers are evaluating taste preferences among three leading brands of cola. After participants taste each brand, the first researcher simply checks to see if participants can distinguish them reliably by labeling each cola as "same" or "different" from the others, by giving them the same or different letter or number code. The second researcher asks each participant to identify the most preferred, the second most preferred, and the least preferred. The third researcher asks each participant to rate each of the colas on a 10-point scale, where a rating of 1 indicates “terrible taste” and 10 indicates “excellent taste," with the assumption that the difference betweeen a rating of 4 and 6 is the same as the difference between a 6 and 8. Identify the scale of measurement used by each researcher.

- A researcher investigated whether a father's level of optimism was predictive of his son's optimism as a young adult. Twenty (20) fathers and sons who agreed to participate in the study were administered a scale measuring their current level of optimism (the scale ranged from 10 to 50), with higher scores indicating greater optimism.arrow_forwardxt:Bong-Cha is deciding what to do during the 30-minute break between her college classes. One rule she could follow is, "Choose the activity with the highest value" (A). Another rule she could follow is, "Choose the activity with the lowest opportunity cost" (B). Do you think Bong-Cha's choice if she follows rule (A) will be the same as the choice she would make if she followed rule (B)? [another way to think about it, "Is rule (A) identical to rule (B) in a sense that they would both induce the same choice?"].arrow_forwardIn 2009 the Organization for Economic Cooperation andDevelopment (OECD) conducted a study of 34 membercountries called the Programme for International StudentAssessment (PISA). The OECD looked at reading scores among 15-year-olds in each country as well as the stu-dents’ socioeconomic backgrounds. PISA reported that higher socioeconomic status was associated with higher reading scores, with their socioeconomic index explain-ing 14% of the variability in reading scores.

- One of the oldest principles of marketing is that sellers may sell features, but buyers essentially buy benefits. This is a distinction sometimes lost on technology ledorganizations, and the service sector is no exception. Recent experience of the UK’s largest telecommunications company, Della’s, illustrates how crucial it is to see service offers in terms of the benefits they bring to customers. The company was aware of extensive research which had found high levels of confusion among purchasers of mobile phones, with a seemingly infinite permutation of features and prices. With four main networks to choose from, dozens of tariffs and hundreds of handsets, it is easy to see why buyers sought a way of simplifying their buying process. Throughout the 1990s, Della’s had positioned its UK network as superior technically to its competitors. Advertising focused on high coverage rates and call reliability.Della’s was the UK's most popular mobile phone operator, with almost eight million…arrow_forwardQuestion:You work as an analyst for the electronics manufacturing firm Hypra!!!, based in Japan. Hypra!!! started as a textile manufacturing firm in the 1950s but from the 2000s it switched to produce the product called x, a high-tech gadget, extremely popular in Japan, but less so in other countries (yet). There are two main groups of consumers who are interested in x. First, teenagers use it for gaming. Second, middle-aged managers are also keen to use it as a personal assistant, not unlike Siri on Apple devices. Presently, four firms are producing x. Hypra!!! has a 38% market share. The x is sold both by specialist stores and the large hypermarkets across Japan. The most important component of the x is called chip+++, which requires a very specific technology, and, therefore, is only produced by two Japanese suppliers, working strongly together with the x producers. A new version of the x tends to be introduced every second year. Hypra!!! has always been the most innovative of the…arrow_forwardDescribe the major differences between a randomized controlled experiment and a quasi-experimentarrow_forward
- 6. Imagine that I wanted to test the proposition that people think older politicians are more trustworthy. I recruited an internet sample of 90 people. Each person was asked to read a short article about a hypothetical political candidate. Random assignment determined whether the subjects were told that candidate was 65 or whether they were told that candidate was 35. After reading the article, all subjects used a 10-point scale to rate the candidate on competence, trustworthiness, and likability. I take the mean values of trustworthiness in each group, perform a difference of means test, and find a test statistic of 1.04. Should I reject the null at the 99% confidence level? Why or why not? What does that mean?arrow_forwardWhen I took the PRCA my scores were much high than the other two tests and I know that this test is essentially showing what my communication apprehension is like and I think that the reason that this test is much lower scored than all the others is because im just not really a communicative person. I do tend to find it at times hard to work with people and many times I would just much rather be tasked with doing something myself so I can get it done my way and I feel like that is just much more of an effective way for me to work on something. And knowing that I am already this way with people that are from a similar background with me then I am more inclined to not work well with people who are more different than that. I'm not unable to work with people I just prefer to work alone. And I had once worked with someone from a different cultural background and It just wasn't for me because I couldn't really understand them through their accent very well and it would frustrate me because…arrow_forwardA company has the head office at Ukraine and a branch at London.

- Venture capital (VC) firms are pools of private capital that typically invest in small, fast-growing companies that can't raise funds through other means. In exchange for this financing, VCs receive a share of a company's equity, and the founders of the firm typically stay on and continue to manage the company. The incentive conflict is between the managers, who are the , and venture capitalists, who are the . VC investments have two typical components: (1) managers maintain some ownership in the company and often earn additional equity if the company performs well; (2) VCs demand seats on the company's board. Placing VCs on the company's board serves to decision-making authority.arrow_forwardContext : The London Metro Bus is crowded for travel during peak hours. During such travel hours two daily passengers ‘James’ and ‘Robert’ enter the Metro. Luckily, two adjacent seats are free in the bus. Each of them must decide whether to sit or stand. For both, sitting alone is more comfortable than sitting next to the other person, which in turn is more comfortable than standing. Question : Assume that both ‘James’ and ‘Robert’ are altruistic, ranking outcomes according to the other person’s comfort and, out of politeness, prefer to stand than to sit if the other person stands. Model the situation as a strategic game and find any Nash equilibrium (equilibria) if it exists. Does a dominant strategy exist for either ‘James’ or ‘Robert’ with these preferences? show ALL steps and working in support to your answerarrow_forwardDuring the Auction session, Tony was so drunk that he didn’t know what he was doing, bid successfully at an auction for the purchase of a house. It was clear to the auctioneer that Tony didn’t know what he was doing. However, after Tony sobered up he confirmed the contract with the auctioneer. He then subsequently refused to complete the contract. Suggest some advice to solve this case.arrow_forward
