Research Description

As a behavioral economist I study how people actually act in the marketplace, as opposed to how they should or would perform if they were completely rational.

I study a wide range of daily behaviors such as buying (or not), saving (or not), ordering food in restaurants, pain management, procrastination, dishonesty, and decision making under different emotional states.
