In first-price sealed-bid auctions, a power probability weighting function is observationally equivalent to a model of constant absolute risk aversion. By comparing auctions with different ceilings on a computerized opponent’s bid space, we can separate subjective probability weighting and...

External reference points, such as outside options or budget constraints, are common in bidding environments. We experimentally investigate the impact of external reference points for bidding in first-price auctions with independent private values. We find that the presence of a reference point...
