Chapter 1, Problem 1.28ACI
Corporate sustainability and firm characteristics. Corporate sustainability refers to business practices designed around social and environmental considerations (e.g., “going green”). Business and Society (March 201 1) published a paper on how firm size and firm type impact sustainability behaviors. The researchers added questions on sustainability to a quarterly survey of Certified Public Accountants (CPAs). The survey was sent to approximately 23,500 senior managers at CPA firms, of which 1,293 senior managers responded. (Note· It is not clear how the 23,500 senior managers were selected.) Due to missing data (incomplete survey answers), only 992 surveys were analyzed. These data were used to infer whether larger firms are more likely to report sustainability policies than smaller firms and whether public firms are more likely to report sustainability policies than private firms.
- a. Identify the population of interest to the researchers.
- b. What method was used to collect the sample data?
- c. Comment on the representativeness of the sample.
- d. How will your answer to part c impact the validity of the inferences drawn from the study?

Business group Business Unity South Africa (BUSA) has written to Transport minister Fikile Mbalula requesting he makes changes to South Africa’s regulations around the transportation of logistics containers. According to BUSA, Regulation 224 (b) of the National Road Traffic Act currently prohibits the transportation of high cube containers on South African roads. “High cube containers constitute the overwhelming majority of containers currently manufactured and transported internationally – including in neighbouring states,” it said. “However, the combined height of a vehicle transporting a high cube container is currently 4.6 metres – 300mm above the legal limit.” Despite several years of industry engaging the Department of Transport on the matter, as well as moratoriums being issued, no progress has yet been forthcoming on fundamentally resolving the issue, the group said. “This regulatory anomaly puts South Africa’s trade and logistics regime out of step with international and…

CASE STUDY: #2
In August 2000, a young woman from Gozo, an island south of Italy, discovered that she was carrying conjoined twins. Knowing that health-care facilities on Gozo were inadequate to deal with the complications of such a birth, she and her husband went to St. Mary’s Hospital in Manchester, England, to have the babies delivered. The infants, known as Mary and Jodie, were joined at the lower abdomen. Their spines were fused, and they had one heart and one pair of lungs between them. Jodie, the stronger one, was providing blood for her sister.
No one knows how many sets of conjoined twins are born each year, but the number has been estimated at 200. Most die shortly after birth, but some conjoined twins do well. They grow to adulthood and marry and have children themselves. But the outlook for Mary and Jodie was grim. The doctors said that without intervention the girls would die within six months. The only hope was an operation to separate them. This would save Jodie, but…

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.

- According to data from Yelp, more than 55 percent of the 132,500 businesses listed on the site that closed during the pandemic will remain shuttered permanently. Although government relief bought some companies time, businesses that are now closed will likely remain that way for the long term. Restaurants account for the greatest share of permanent and temporary closures, followed closely by retailers and then beauty salons and spas. “Businesses are needing to decide, ‘Do I renew my lease on my space for another year?’ It is really hard to make a one-year commitment to paying rent when businesses are closing down for the second time and there’s no end in sight to this virus,” said Michael Stepner, a postdoctoral researcher at Harvard University. “The longer these temporary closings go on, the more of them will turn permanent.” States that depend heavily on tourism like Hawaii and Nevada have experienced the most closures per capita.

The company wants to build a regional shopping center in a nearby city that is surrounded by a large rural population. To help them conduct a feasibility study, please address the following questions. 1. What type of population-related decisions should be made to determine the best location for the shopping center? For example, is there a demand for new retail stores? 2. What type of population and related information would you need to collect to help determine the best location for the center? 3. What types of analysis would you perform with the information?arrow_forwardScenario In a major metropolitan area, there are many coffee shops, but one chain has gained a large market share because customers feel its coffee tastes better than its competitors'. There are hundreds of high school students in need of algebra tutoring services. Dozens of companies offer tutoring services; parents view the quality of the tutoring at the different companies to be largely the same. In a small town, there are four providers of broadband Internet access: a cable company, the phone company, and two satellite companies. The Internet access offered by all four providers is of the same speed. Almost everyone in the city already has broadband, so any potential new company would have to engage in a price war with the existing companies and would be unlikely to cover its costs for years, if ever.

- Amazon could launch a smartphone this year that costs “a fraction” of what Apple charges for its iPhone, a new report says. Amir Efrati at The Information spills details from an allegedly leaked internal Amazon document. The paperwork is said to have been produced by a potential partner and two people who were involved in discussions with Amazon. According to Efrati, the document discussed strategies for penetrating smartphone markets in China, Europe and the United States. Earlier discussions also mentioned Latin America as a possibility. The phone, which has been referred to as “Project Aria,” is likely to go on sale this year, according to Efrati. There’s no specific price, but he says Amazon is “determined” to “keep the phone at a small fraction of the iPhone’s $550-and-up price tag.” If Amazon does launch a smartphone this year, it’s unclear if it will fall under the company’s own brand or if it will work with a partner.

The maximum amount that group 1 is willing to pay for room and board is GHC 2500 and for entertainment is GHC 500. For group 2, the maximum amount they are willing to pay for room and board is GHC 1800 and for entertainment is GHC 750. Although AG Travel and Tour is not able to identify members of either group, it does know that each group values the components of the package differently. Assuming there are an equal number of members in each group and that the total membership in each group is a single individual. If the marginal cost of providing the service (room and board and/or entertainment) to each group is GHC 1000.i.

Office staff are spending too long on the social networking site. According to The Associated Chambers of Commerce and Industry (Assocham) employees use Orkut, Facebook, Myspace, and Linkedin for "romancing" and other purposes. On average, employees spend an hour a day on sites like Facebook. This reduces productivity by 12.5%. Nearly half of office employees accessed Facebook during work time. Some 83% saw nothing wrong in surfing at work during office hours. In September 2009 Portsmouth City Council in England banned staff from accessing Facebook on its computers when it was discovered that they spent, on average, 400 hours on the site every month. Question What is meant by productivity? Analyze the impact on a fall in productivity on costs. Analyze the possible consequences for businesses in India of banning access to Facebook and other social networking sites. Do you think access should be denied?arrow_forward
