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.

If you are human, you can’t help but experience times when everything seems to be going wrong. You must also _36__as if your life is completely out of control at times. It is during those “down times” that words of encouragement from family, friends, co-workers or __37_strangers can boost(增强)your spirits. It is also during those __38_that negative words can be devastating (毁灭性的) and sink you deeper and deeper into depression.
For example, consider this story about a group of _39__who were traveling through the woods when __40__of them fell into a deep pit(坑). All of the other frogs gathered around the __41__.When they saw how _42__the pit was, they told the two _43__frogs they would never get out.
The two frogs didn’t obey what other frogs said and tried to __44__ out of the pit. The other frogs kept telling them not to jump, _45__it was in vain. Finally, one of the frogs followed what the other frogs were saying and simply _46. He fell down and _47_. The other frog continued to jump as __48_as he could. Once again the crowd of frogs shouted at him to _49__ the pain. The more they _50__, the harder he jumped and finally he __51__to safety.
When he __52_, the other frogs asked him why he continued to jump when they were all __53__him to simply quit. The frog __54_to them that he was a little bit deaf. He thought they were _55__him all the time.
