Chapter 5.S, Problem 11P
A Southern Georgia school district is considering ordering 53 propane-fueled school buses. “They’re healthier, they’re cleaner burning, and they're much quieter than the diesel option.” said a school administrator. Propane-powered buses also reduce greenhouse gasses by 22% compared to gasoline-powered buses and 6% compared to diesel ones. But they come at a premium $103,000 for a propane model, $15,000 more than the diesel equivalent.
The propane bus operating cost (above and beyond fuel cost) is 30 cents/mile, compared to 40 cents for the diesel. Diesel fuel costs about $2/gallon in Georgia, about SI more than propane.
Bus mileage is 12 mpg for the propane model vs. 10 mpg for diesel. The life of a school bus in the district averages 9 years, and each bus travels an average of 30,000 miles per year because the district is so large and rural.
Which bus is the better choice based on a life-cycle analysis?

A Southern Georgia school district is considering ordering 58 propane-fueled school buses. "They're healthier, they're cleaner burning, and they're much quieter than the diesel option," said a school administrator. Propane-powered buses also reduce greenhouse gasses by 25% compared to gasoline-powered buses and 8% compared to diesel ones. But they come at a premium—$97,000 for a propane model, $17,000more than the diesel equivalent.
The propane bus operating cost (above and beyond fuel cost) is 40 cents/mile, compared to 49cents for the diesel. Diesel fuel costs about $4/gallon in Georgia, about $1 more than propane. Bus mileage is
9 mpg for the propane model vs. 7 mpg for diesel. The life of a school bus in the district averages
10 years, and each bus travels an average of 34,000 miles per year because the district is so large and rural. Which bus is the better choice based on a life-cycle analysis?

The Lo-Jack recovery system allows the police to track stolen cars. As a result, they not only recover 90% of Lo-Jack-equipped cars that are stolen but also arrest many auto thieves and shut down many "chop shops" that take apart stolen vehicles to get at their used parts. Thus Lo-Jack provides both private benefits and positive externalities. Should the government consider subsidizing Lo-Jack purchases?

His first step, which he has repeated in other cities, was to partner with local public-transportation boards, universities and businesses to help market his program. For instance, in some cities Flex car has made deals with transit officials that let the company offer its customers passes for public buses and trains. And some employers partially subsidize Flex car memberships as a perk for their employees. Mr. Peterson's marketing tried to position car sharing as liberating, offering slogans such as "Why buy wheels when you can borrow them?" Flex car’s ads also urge drivers to "Shift your thinking" about car ownership--don't look at a car as a status symbol but as a means of getting around. Don't even look at it as property, in fact; think of it more as a time-share vacation home. Car sharing "gives you a short-term relationship, kind of like getting a motel room instead of buying a house," says…arrow_forwardAmy lives in Papar but works in Kota Kinabalu. After struggling for years with public transport such as mini-buses and the train and receiving many complaints from fellow travelers, she has decided to look into providing several upgraded bus services in and around Kota Kinabalu which would provide more comfort and hygiene. The busses will be modern, air-conditioned and either hybrids or electrical. Amy is using the public transport busses as used in KL as a model. The prices charged to the customer would be somewhat above the current mini-bus prices but Amy believes that many commuters will be more than willing to pay a bit extra for a comfortable and safe alternative. Prepare Porter’s Five Forces for Amy’s planned bus services.arrow_forward
- What are some of the disadvantages of chargeback systems?arrow_forwardAs mentioned in the chapter, some analysts predict barcodes maybe replaced by a wireless technology called radio-frequency identification (RFID). RFID is a system of installing tags containing tinycomputer chips on, say, supermarket items. These chips automatically radio the location of the item to a computer network whereinventory data is stored, letting store managers know not onlywhere the item is at all times but also when and where it was madeand its color and size. Proponents believe RFID cuts costs and simplifies inventory tracking and reordering. It may also allow marketersto respond quickly to shifts in demand, avoid under- and overstocking, and reduce spoilage by automatically removing outdated perishables from the shelves. Privacy advocates, however, think thechips provide too much product-preference information that mightbe identified with individual consumers. In the meantime, Walmartrequires its major suppliers to use the new technology on productsstocked by the giant…arrow_forwardMidland Transmissions and Axels Inc. has been a very successful business catering to the light duty trucking industry for the past 11 years.

The company is now faced with the need to quickly raise $60 million dollars in order in business. Old Dominion Bank and Bonds, Inc. a leading bank chartered in Hamilton, Ontario, is threatening Midland and Transmissions, that as a result of their defaulting on a $500 thousand payment o their secured $25 million long-term bond indenture, they probably will go to court to force bankruptcy proceedings.

Located in a local outdoor shopping center, parking in front of Sonnie’s is limited. However, there are many parking spaces available behind the café within a five-minute walk. The café has an inviting, bright, and open interior with deli cases, blackboards listing specials, and oak tables and chairs. The café’s popularity at lunch is a concern for Sonnie. During the prime lunch time, between 11:30 a.m. and 1:30 p.m. Monday through Friday, the waiting line is often out the door. On average Sonnie would like to serve 40 customers per hour at lunch. Working professionals, who typically spend more than other customers at lunch, are on busy schedules and do not have time to wait in line. Sonnie estimates that currently some customers go to other restaurants because of the line. The menu at Sonnie’s includes nine standard sandwiches such as roast beef, pastrami and rye, and a…arrow_forward
