Abstract

We introduce the speculation elicitation task (SET) to measure speculative tendencies of individuals. The resulting SET-score allows us to investigate the role of individual speculative behavior on experimental asset market bubbles. The experimental results show that overpricing in asset markets composed of subjects with a high propensity to speculate (high SET-score) is significantly higher than in markets composed of subjects with a low propensity to speculate (low SET-score). We conclude that speculative tendencies are an important driver of price bubbles in experimental asset markets.
