    Negotiation is a critical skillset in business and in society. Negotiation is a complicated, joint decision problem where parties can, potentially, make each other better off—but also have some competing interests.

    It’s 9 am. Do you know where your team members are? Before Covid, the answer was simple: They were – or were expected to be – in the office. The pandemic erased that certainty and accelerated the pace toward work-place flexibility. As we move forward in our post-covid work environment, employees are strongly indicating their preference for flexibility and self-determination regarding their working environment. A portion of the workforce will desire to stay at home with high flexibility, whereas others will return to the office by choice.

    Selling is inseparable from relationship management. In the past, the one-to-one "human touch" of a salesperson compensated for the standardized nature of their wares. However, today's sales environment tends towards customized solutions and co-creation with the client, especially in the B2B space. In many cases, these trends have greatly increased the network of stakeholders whom salespeople are obliged to keep happy. Research shows that B2B customers benefit from being more involved in the process, but what about the sales force? Does their increased interpersonal burden translate to higher risk of burnout? George Mason University School of Business Marketing Area Chair Jessica Hoppner's recently published paper in Industrial Marketing Management, co-authored by Paul Mills of Cleveland State University and David A. Griffith of Texas A&M University, finds some surprising answers.

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.

    Corporate 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.

    Exceptions 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.
