Group buying isn't a new concept, say U of T researchers. Mozart (pictured) and Beethoven used this method to sell concert tickets. (Wikimedia Commons photo)

U of T researchers examine recent success of this approach

We might like to think we're not influenced by other people, but new research from the University of Toronto鈥檚 Rotman School of Management indicates otherwise, especially when it comes to consumer behaviour.
 
A new study into group buying mechanisms -- like those used on popular Internet websites such as Groupon and LivingSocial -- reveals that the number of purchasers increases if buyers who come later to the offer are told how many people have already signed up.
 
Researchers at the Rotman School of Management wanted to understand why group buying sites that have entered the market recently have enjoyed greater success than those that were operating a decade ago, such as Mercata and MobShop. It turns out that earlier sites typically left potential buyers waiting for days before confirming whether or not they had received the offer they had signed up for, something not true today.
 
鈥淲e think one of the reasons group buying has been successful recently is because of the short time horizon,鈥 says Rotman professor Ming Hu, who co-wrote the study with Professor Mengze Shi and PhD student Jiahua Wu. 鈥淚t allows for a herding effect.鈥
 
Another reason for the greater success of recent sites 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 a sequential mechanism, where a second group of buyers has the advantage of knowing the size of the first group.
 
The researchers' analytical 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.
 
鈥淭hat boosts confidence,鈥 said Hu, who teaches operations management. Deals for 鈥渓uxury鈥 services, vs. everyday items, work better in a group buy scenario because they offer consumers a greater benefit.
 
Group buying sites have become increasingly popular recently, but group buying has appeared in various incarnations for hundreds of years.

Often, the success of a venture is dependent upon participation. The website Kickstarter.com links artists with potential buyers who can contribute to the artist's proposed project. If enough buyers commit to financially support the project, the project goes ahead. Musicians such as Beethoven and Mozart used the same mechanism to sell tickets to their concerts.
 
Group buying has also been used to obtain discounts -- if enough buyers commit within a certain timeframe, they can obtain a substantial cut on the regular price.

Although a hallmark of most group buying sites is that committed money is refunded if the deal gets called off, purchasers still experience a "psychological loss" when that happens, and may be more willing to sign on to a deal they feel is guaranteed to happen.
