Hongjun Yan embraces unconventional thinking. It's a mindset that drove this scholar to become an innovative finance professor and to join DePaul's business faculty in July as Driehaus Chair in Behavioral Finance.
Yan switched his focus to business, earning a master's in management science, and then entered the London Business School's finance PhD program. He studied classical finance models, in which investors are assumed to have all the knowledge, analytical power and self-control needed to make rational investing decisions, without the bias of human behavior. But Yan questioned this thinking and found himself drawn to alternative theories of behavioral finance, an emerging academic field that took behavioral biases seriously.
"Growing up in a society that went through dramatic transformation, it is natural for me to be skeptical about mainstream views," Yan says. "I found it appealing when the research in behavioral finance started challenging the mainstream." Behavioral finance not only provides a fresh perspective for understanding investor decision-making, he explains, but it also yields new insight into the behavioral influences that affect asset pricing and policymaking.
After obtaining his PhD, Yan taught finance at Yale University for 10 years, where he built an impressive record of research. His scholarly work probes how asset pricing is affected by market imperfections and "bounded rationality," which are anomalies in investors' behavior caused by their limited knowledge, information and time. Yan also taught at Rutgers before joining DePaul.
At DePaul, he continues this inquiry while teaching finance classes and leading the Driehaus Center for Behavioral Finance as academic director. The center, which promotes research into the human aspects of financial decision-making, and Yan's chairmanship are endowed by a 2002 charitable trust gift from Richard H. Driehaus (BUS '65, MBA '70, DHL '02), founder of Driehaus Capital Management and a proponent of behavioral finance.
Driehaus applauded the choice, calling Yan "an impressive thought leader whose work is advancing the knowledge and application of behavioral finance theories among students, academics and industry professionals."
Yan says his goal at DePaul is to nurture an "elite institute in behavioral finance." He also relishes challenging a new generation of business students to question conventional thinking about finance.
"I always strive to encourage my students to have a healthy dose of skepticism toward what they learn," he says. "I want them learn how to use the models, and, more importantly, when and how not to use those models."
