We might like to think we're not influenced by other people, but a new study into the group-buying mechanisms（机制） - like those used on coupon（优惠券） sites such as Groupon and LivingSocial - reveals that telling buyers who come later to the offer how many have already signed up increases the number of purchasers.
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.

You’re only three years old, and at this point you are not able to understand this letter today. But someday, when you _36_, I hope you will find something _37_ in what I share with you.A few months ago as I wandered through my parents’ house, the same house I grew up in, I had a sudden, scary realization. When my parents bought the house, in 1982, they were only two years older than I am now. I tried to imagine myself in two years, ready to settle down and buy the house I’d still be living in almost 30 years later.
It seemed ridiculous. On a practical level, there’s no way I could afford to buy a house anytime soon. More importantly, I wouldn’t want to. I’m not sure where I’ll be living in two years, or what kind of job I’ll have. And I don’t think I’ll be ready to settle down and stay in one place.
So this is probably the generation gap that divides my friends and me from our parents. When our parents were our age, they’d gotten their education, chosen a career, and were starting to settle into responsible adult lives.
My friends and I – “Generation Y” – still aren’t sure what we want to do with our lives. Whatever we end up doing, we want to make sure we’re happy doing it. We’d rather take risks first, try out different jobs, and move from one city to another until we find our favorite place. We’d rather spend our money on travel than put it in a savings account.
This casual attitude toward responsibility has caused some critics to call my generation “arrogant”, “impatient”, and “overprotected”. Some of these complaints have a point. As children we were encouraged to succeed in school, but also to have fun. We grew up in a world full of technological innovation: cellphones, the Internet, instant messaging, and video games.
Our parents looked to rise vertically(垂直的)--starting at the bottom of the ladder and slowly making their way to the top, on the same track, often for the same company. That doesn’t apply to my generation.
Because of that, it may take us longer than our parents to arrive at responsible, stable adulthood. But that’s not necessarily a bad thing. In our desire to find satisfaction, we will work harder, strive for ways to keep life interesting, and gain a broader set of experiences and knowledge than our parents’ generation did.
