CATONSVILLE, MD, October 10, 2017 – In the U.S. today, the majority of professional stock market traders are young males and new evidence suggests biology strongly influences their trading behavior. According to a new study in the INFORMS journal Management Science, this could be a significant contributor to fluctuations in the market, as high testosterone levels can cause these traders to overestimate future stock values and change their trading behavior, leading to dangerous prices bubbles and subsequent crashes.

CATONSVILLE, MD, October 9, 2017 - In 2008, New York City mandated all chain restaurants to post the calories of items on their menus. The intent was to induce consumers to choose healthier items in the restaurant. A forthcoming study in the INFORMS journal Marketing Science, a leading scholarly marketing publication, investigated whether the calorie posting on menus has broader spillovers by impacting consumer evaluations of the restaurant. The study finds that health mentions about the foods increased significantly in online reviews after the calorie posting regulation. The result suggests that calorie posting can not only shift consumers towards healthier alternatives when inside a restaurant, but can also have spillovers on other customers reading the reviews by potentially redirecting them towards healthier restaurants and food items.
