Strategic thinking in contests

We examine motives for ‘overbidding’ in contests between individuals using a “two-headed” approach to decision-making. In “two-headed” contests, subject pairs send suggested bids and messages to a partner. Content analysis of the messages provides insight into an individual’s bidding motives. In addition, we elicit measures of preferences, beliefs, and impulsiveness. We find that beliefs about others’ bids and messages that emphasize winning (i.e., utility of winning) are the most robust predictors of ‘overbidding’. Our results suggest that analyzing communication provides a rich window into an individual’s thought process when making decisions, and can complement insights from elicited values from common decision tasks (Replication materials, including data, do files, and software, are available at https://sites.google.com/view/david-bruner/research ).
