Somehow ice and cold water have become the social media phenomenon of the summer. Millions of people have shivered and screamed while dumping buckets of ice over their own heads, and a medical charity has tens of millions of dollars raised as a result. Yale Insights spoke with Yale economist Florian Ederer to try to make sense of all of this.

Laboratory experiments have suggested that, counterintuitively, having both an internal motivation for completing a task and an external reward makes performance weaker. A study by Yale SOM’s Amy Wrzesniewski tested this idea in the real world, by examining how the motivations of West Point cadets affected their performance. The results have strong implications for how leaders can get the best performance from their organizations.

What kinds of motives are most conducive to success? In a New York Times op-ed, Professor Amy Wrzesniewski and coauthor Barry Schwartz discuss their research looking at the motives of new West Point cadets and how they relate to success as Army officers.

Recent research, drawing on behavioral economics, suggests that donors make larger contributions to a nonprofit organization when they have a sense of active involvement in the organization's mission. In an op-ed for the New York Times, Professor Robert Shiller suggests that changes to legal and institutional structures could be powerful new tools to increase engagement and giving.

The degree of physical contact that a celebrity has with a piece of memorabilia affects how much collectors are willing to pay for it at auction, according to a study co-authored by Professor George Newman.

To reduce subtle biases that limit women and minority academic scientists, research universities should design diversity programs that adhere to rigorous scientific standards, according to a new paper co-authored by Professor Victoria Brescoll.

Nobel laureate Robert Shiller discusses some of the trends he currently sees in finance and the housing market.

Professor Ravi Dhar runs through how recent research in psychology helps explain how we all make decisions when shopping. When are you impulsive? When do you really think things through? When do you make the good long-term choice? And when do you go for the junk food?

In the New York Times, Professor Robert Shiller writes that the United States should reduce government subsidies for homeownership, while finding another way to promote household saving.

New research co-authored by Professor Olav Sorenson finds that managers are biased against ideas that are proposed by employees outside of their own work groups, hurting innovation and performance.
