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…
xt: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?"].
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.

- A tax on Cigarettes introduced in Mexico in 2012 increased the price of Cigarettes by about 10%. An evaluation of the first two years of this measure found that Cigarette consumption fell on average by 7.6%, with a larger decrease (11.7%) in low income households. The study also estimated an increase in consumption of alternatives to smoking, particularly Nicotine patches, of 2.1% (AYA, 2017) Explain factors that determine responsiveness to a price increase. Which of these factors might explain the difference in the economy and low income households?arrow_forwardIn 2009 a survey found these airline preferences for people in Southeast Asia when choosing to fly to China: 40%, Thai Airlines; 41%, Singapore Airlines; and 19%, Cathay Pacific.

- 7. Some years ago, a new brand of toothpaste was introduced in the United States. According to its advertisements, studies showed that it had "considerable success" in improving the health of a person's teeth. Suppose that these studies were designed in the following way. The manufacturer of this toothpaste chose three samples of seven people; the first sample agreed to use the new brand, the second sample used Brand A, and the third sample used Brand B. After six months, a dentist examined each person's teeth and scored the health of his or her teeth on a scale of 0 (lowest possible score) to 100 (highest possible score). The results were as follows: New Brand Brand A Brand B 65 58 54 71 60 38 53 63 43 55 90 61 34 95 94 82 89 96 77 62 82 The manufacturer of the new toothpaste says that the average score for the new brand is 2 points higher than for Brand A and 4 points higher than for Brand B. Would you agree with the manufacturer's advertisements? Explain.arrow_forwardTwo travelers on a plane have identical luggage and each contains an identical plate of rare china.

(1982) report on a drug designed to reduce hypertension (high blood pressure). Such hypotensive drugs are frequently effective but are also linked to side effects like irritability and a decline in energy. Seventy-five patients with mild hypertension were put on hypotensive drugs and their progress was monitored by doctors and spouses. When asked to rate the treated patients as improved, worse, or unchanged, the doctors rated all 75 patients as "improved." Meanwhile, the spouses rated 74 of the 75 patients as "worse." Why might spouses and doctors differ in their opinion about the effect of going on blood pressure medication?arrow_forward
- Exercise 3.13 —*** Challenging Question ✶✶✶. Two women, Anna and Bess, claim to be the legal owners of a diamond ring that - each claims - has great sentimental value. Neither of them can produce evidence of ownership and nobody else is staking a claim on the ring. Judge Sabio wants the ring to go to the legal owner, but he does not know which of the two women is in fact the legal owner. He decides to proceed as follows. First he announces a fine of $F > 0 and then asks Anna and Bess to play the following game. Move 1: Anna moves first. Either she gives up her claim to the ring (in which case Bess gets the ring, the game ends and nobody pays the fine) or she asserts her claim, in which case the game proceeds to Move 2. Move 2: Bess either accepts Anna's claim (in which case Anna gets the ring, the game ends and nobody pays the fine) or challenges her claim. In the latter case, Bess must put in a bid, call it B, and Anna must pay the fine of $F to Sabio. The game goes on to Move 3.

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.

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_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_forward
