October 19, 2022For most drivers in the U.S., obeying a stop sign upon approaching an intersection is an unavoidable annoyance. But for Mason finance professor Jiasun Li, it’s a problem waiting to be solved. His recent working paper proposes a simple and economical improvement: removing one stop sign from every four-way intersection. According to his calculations, this would boost not only driver safety, but environmental sustainability as well.
October 12, 2022Corporate social responsibility (CSR) has been on the business leadership agenda for more than 50 years, yet executives and corporate boards still demand to see the "business case" for CSR. Clearly, CSR’s familiarity as a concept has not translated into coherent ideas of where it fits into the cost-benefit calculations that motivate business strategy. A forthcoming article in the Journal of Financial and Quantitative Analysis by Lei Gao, associate professor of finance at George Mason University School of Business, Jie (Jack) He (of University of Georgia) and Juan (Julie) Wu (of University of Nebraska – Lincoln) goes beyond the business case to form cause-and-effect connections involving companies’ CSR efforts.
September 22, 2022Exceptions may prove the rule, but they must first be explained. That is why finance researchers are drawn to the distress anomaly-- a well-documented phenomenon that challenges the risk-return paradigm in equity markets. Generally, higher-risk investments are expected to yield higher returns than safer, more stable securities. In recent years, however, studies have shown that high-credit-risk securities for companies in distress – i.e. when their already-low credit rating is being downgraded -- realize abnormally low returns compared to non-distressed securities of the same or lower risk. Academics have proposed a range of rationales for this puzzle. Alexander Philipov, finance area chair and associate professor at George Mason University, says they mainly fall into two categories.
