Bidding for Nothing? The Pitfalls of overly Neutral Framing

Abstract

Neutral framing is a standard tool of experimental economics. However, overly neutral instructions, which lack any contextual clues, can lead to strange behavior. In a contextless second price auction for a meaningless good, a majority of subjects enter positive bids - a case of cognitive experimenter demand effect. Subjects bid positive amounts because this is what they think they are tasked with in the experiment. Adding a second auction that has a context drastically reduces the positive bids in the meaningless first auction by reducing the cognitive experimenter demand effect.
