The institute has already helped two recent participants.

The John Pappajohn Entrepreneurial Center:

The Iowa Electronic Markets (IEM) is an ongoing research project that tests the prediction of markets to predict future events. The IEM offers markets that try to predict the outcome of political elections, influenza outbreaks, hurricane landfalls, and movie box office grosses.

There are five Tippie professors who are involved as faculty advisors or director of the IEM. They all can discuss the uses and functions of prediction markets:

A recent study found that the IEM was more accurate than 74 percent of public opinion polls at predicting vote percentage in presidential elections between 1988 and 2004.

Dhananjay (DJ) Nayakankuppam, associate professor of marketing and Henry B. Tippie Research Fellow,, 319-335-1981
Nayakankuppam’s research has found that when it comes to shopping, sometimes ignorance really is bliss. In what he terms the Blissful Ignorance Effect, Nayakankuppam found that people who have only a little information about a product are happier with that product than people who have more information.

Thomas Gruca, Henry B. Tippie Research Professor of Marketing,, 319-335-0946
Gruca researches the use of prediction markets to help businesses make marketing and other planning decisions.

Johannes Ledolter, professor of management sciences/statistics/actuarial sciences and C. Maxwell Stanley Professor of International Operations Management,, 319-335-3814
Readers would rather buy a magazine from Kelly Ripa than Dr. Phil. Ledolter discovered this nugget as part of a project he undertook that helped Des Moines-based Meredith Publishing increase subscriptions for its Ladies Home Journal title. Ledolter’s work with Meredith demonstrates that many businesses are missing an opportunity to build their customer base by ignoring a statistical technique called experimental design.

Jing Wang, associate professor of marketing and Leonard A. Hadley Research Fellow,, 319-335-0843
When businesses pay millions of dollars to advertise, they don't expect to make their potential customers mad at them. But Wang's research suggests that in some cases, they might be doing just that. Her work found that television viewers and magazine readers look poorly on advertisements if they are entertained by the story the ad interrupts. In fact, she said, the more engrossed the viewer is in the story, the more intense their negative reaction to the advertised product will be.

Barrett Thomas, associate professor of management sciences and Leonard A. Hadley Research Fellow,, 319-335-0938

Philip C. Jones, professor of management sciences and Clement T. and Sylvia H. Hanson Family Chair in Manufacturing Productivity,, 319-335-3737

Yes, the handshake is as important as everyone says it is when looking for a new job, according to Stewart’s research.

Brian Richman, director of the Hawkinson Institute of Business Finance and lecturer,, 319-335-0853
Investment banks may be collapsing and merging themselves out of existence, but Richman says jobs will still be available in the field.

Frank Schmidt, professor emeritus of management and organizations,, 319-335-0949
Schmidt helped to develop two data analysis methods in the 1970s that changed the way people thought about standardized tests, particularly as they related to businesses hiring and developing employees.

Todd Houge, Curt and Carol Lane Research Fellow and lecturer in finance,, 319-335-3754
Houge has found evidence that mutual fund companies take advantage of less knowledgeable investors by charging higher fees on funds that charge sales loads, the kind of funds in which less savvy investors are more likely to put their money.

Houge is also the faculty advisor to the Henry Fund, a student-managed investment fund that has been named the top fund in its class for four straight years.

Brian Richman, director of the Hawkinson Institute of Business Finance and lecturer,, 319-335-0853
Richman worked in the investment banking field and now teaches Tippie College students how to succeed in the field as director of the Hawkinson Institute of Business Finance.

David Bates, professor of finance and W.A. Krause Research Fellow,, 319-353-2288

David Barker, adjunct professor of finance,, 319-353-3756

Gleason’s research looks at how accounting rules and tax laws impact corporate earnings.

Jeffrey Ohlmann, associate professor of management sciences and Huneke Research Fellow,, 319-335-0837
Ohlmann has developed a decision-making model that utilizes mathematical techniques to maximize the value of the players a team drafts. At its heart, the model tries to help fantasy drafters overcome the fundamental handicap of not knowing what players will be available to draft in future rounds.

Eean Crawford, assistant professor of management and organizations,, 319-335-2884

Crawford's research examines employee surveys. Too many questions from the company may give workers polling fatigue, he says, and employees may grow disillusioned if their rapid-fire feedback doesn’t get a timely response.


Ning Li, assistant professor of management and organizations,, 319-335-2117

Research by Li finds that sometimes leaders don't need to be transformational to lead a highly productive group. Rather, leaders need to take the pulse of their teams and establish the extent to which team identification is high. Li has also explored the connection between employee motivation and personality.
