Researchers at the University of Toronto"s Rotman School of Management wanted to understand why group buying sites that have entered the market recently have enjoyed greater success than those operating a decade ago, such as Mercata and MobShop.
Earlier attempts typically left potential buyers waiting for days before confirming whether or not they had got the offer they had signed up for.
“We think one of the reasons group-buying has been successful recently is because of the short time horizon,” says Rotman Professor Ming Hu, who co-wrote the study with Professor Mengze Shi and PhD student Jiahua Wu. “It allows for a herding effect.”
Another reason is the use of an information structure that discloses to later arrivals how many have already signed onto the deal.
Researchers looked at two ways of designing the purchasing mechanism for a group buy:a simultaneous mechanism, where no one knows how many buyers have come before them, and asequential(连续的) mechanism, where a second group of buyers has the advantage of knowing the size of the first group.
The researchers" analytical(分析的) model shows the most successful mechanism is the sequential one because it eliminates uncertainty for those coming later to the deal, and improves the confidence of those who sign on early, as they"re able to track the numbers of those who come after them.
“That boosts confidence,” says Professor Hu, who teaches operations management. Deals for "luxury" services, versus everyday items, work better in a group buy scenario(方案) because they offer consumers a greater benefit.

A.the short time horizon is the reason why group-buying has been successful. |
B.a simultaneous mechanism is where a group of buyers has the advantage of knowing how many people have signed up. |

举一反三
Dear Daughter,
As we drove off from Columbia, I wanted to write a letter to you to tell you all that is on my mind.
First, I want to tell you how proud we are. Getting into Columbia is a real testament( 证明)of what a great well-rounded student you are. You should be as proud of yourself as we are.
Your college years will be the most important of your life. It is in college that you will discover what learning is about. This will be the period when you go from teacher-taught to master-inspired, after which you must become self-learner. So do take each subject seriously, and even if what you learn isn’t extremely impotant for your life, the learning skills you gain will be something you will cherish(怀念) forever.
Follow your passion in college. Take courses you think you will enjoy. Don’t be trapped by what others think or say, but make up your own mind.
Most importantly, make friends and be happy. College friends are often the best in life. Pick a few friends and become really close to them – pick the ones who are sincere and honest to you. Don’t worry about their hobbies, grades, looks or even personalities.
Start planning early – what would you like to do? Where would you like to live? What would you like to learn? I think your plan to study fashion is good, and you should decide where you want to be, and get onto the right courses.
Whether it is summer-planning, or coursework planning, or picking a major, or managing your time, you should take control of your life. I will always be there for you, but the time has come for you to be in the driver’s seat – this is your life, and you need to be in control. Being in control feels great. Try it, and you’ll love it!
College is the four years where you have:
l The greatest amount of free time
l the first chance to be independent
l the most flexibility(灵活性)to change
l the lowest risk for making mistakes
So please treasure your college years – make the best of your free time, become an independent thinker in control of your destiny(命运), be bold(敢于冒险的) to experiment, learn and grow through your successes and challenges.
May your years at Columbia be the happiest of your life, and may you become just what you dream to be.
Love,
Dad (&Mom)

Inside the pleasingly fragrant cafe, So All May Eat(SAME) in downtown Denver ,the spirit ofgenerosityis instantly noticeable :donation box stands in place of a cash register. Customers here pay only what they can afford, no questions asked.A risky business plan, perhaps, but SAME Café has done one unchangeable thing in the Mile High City for six years: Open only at midday, the restaurant allows poor local customers who cannot pay to work as volunteers instead. They can act as waiters and waitresses, and dishwashers, or look after the buildings and equipment for the cafe.
It’s based on trust, and it’s working all right”, says co-owner Brad Birky, who started the café in 2006. Previously volunteering at soup kitchens, the Birkys were dissatisfied with the often unhealthy meals they served there. “We wanted to offer quality food in a restaurant where everyone felt comfortable, regardless of their circumstances,” Birky says. SAME’s special lunch menu changes
daily and most food materials are natural and grown by local farmers. The café now averages 65 to 70 customers (and eight volunteers) a day. And the spirit of generosity behind the project appears to be spreading. In early 2007,one volunteer who had cleared snow for his meals during t he long
winter said goodbye to the Birkys, He said he was going to New Orleans to help with the hurricane clearing up,” says Birky.
小题1:What can we learn about the soup kitchens the Birkys previously worked for?
A.They refused to have volunteers. |
B.They offered low quality food. |
C.They provided customers with a good environment. |
D.They closed down because of poor management. |
A.The customers who cannot pay can work as volunteers instead. |
B.More volunteers will go to new Orleans for the hurricane cleanup. |
C.Many new cafes will be opened to offer free lunches in the town. |
D.The lunch menu has remained the same since the café was started. |
A.unfavorable | B.doubtful | C.cautious | D.approving |

Maybe it was the strange 26 things looked and sounded in my familiar room at night that 27 me so much. There was never total 28 , but a streetlight or passing car lights 29 clothes hung over a chair take on(呈现) the 30 of a wild animal. Out of the corner of my 31 , I saw the curtains seem to move when there was no 32 . A tiny sound in the floor would seem a hundred times louder than in the daylight. My 33 would run wild, and my heart would beat fast. I would 34 very still so that the “enemy” would not discover me.
Another of my childhood fears was that I would get lost, 35 on the way home from school. Every morning I got on the school bus right near my home .That was no 36 . After school, 37 , when all the buses were 38 up along the street, I was afraid that I’d get on the wrong one and be taken to some 39 neighborhood. On school or family trips to a park or a museum, I wouldn’t let the leaders out of my 40 .
Perhaps one of the worst fears 41 all I had as a child was that of not being liked or 42 by others. Being popular was so important to me 43 , and the fear of not being liked was a 44 one.
One of the processes(过程) of growing up is being able to 45 and overcome(克服) our fears. Understanding the things that frightened us as children helps us achieve greater success later in life.

Sir Steven Redgrave
Winner of 5 Olympic Gold Medals
“In 1997 I was found to have developed diabetes(糖尿病). Believing my career was over, I felt extremely low. Then one of the specialists said there was no reason why I should stop training and competing. That was it — the encouragement I needed. I could still be a winner if I believed in myself. I am not saying that it isn’t difficult sometimes. But I wanted to prove to myself that I wasn"t finished yet. Nothing is to stand in my way.”
Karen Pickering
Swimming World Champion
“I swim 4 hours a day, 6 days a week. I manage that sort of workload by putting it on top of my diary. This is the key to success — you can’t follow a career in any field without being well-organized. List what you believe you can achieve. Trust yourself, write down your goals for the day, however small they are, and you’ll be a step closer to achieving them.”
Kirsten Best
Poet & Writer
“When things are getting hard, a voice inside my head tells me that I can’t achieve something. Then, there are other distractions, such as family or hobbies. The key is to concentrate. When I feel tense, it helps a lot to repeat words such as ‘calm’, ‘peace’ or ‘focus’, either out loud or silently in my mind. It makes me feel more in control and increases my confidence. This is a habit that can become second nature quite easily and is a powerful psychological tool.”
