We use the Emmy Award-winning game show Cash Cab to study decision-making in a risky framework. This is a unique environment because, unlike other studies on risk-aversion, players participate individually or in teams varying in number from two to five. This creates a natural laboratory to measure performance and risk aversion conditional upon the size of the team as well as the characteristics of the team members. Our results are striking. Teams are much more likely to complete overall tasks successfully. There are noted differences conditional on gender makeup of the groups. Most importantly, risk aversion estimates indicate that when participants are part of a group, they focus on the overall size of the dollar amounts that are “at risk”, rather than their “slice of the pie”. The implications of our results span a number of areas where groups are part of the financial decision-making process, including investment analysis and portfolio management, corporate governance, and corporate finance.
