How Do Prior Outcomes Affect Risky Choice? Further Evidence on the House-Money Effect and Escalation of Commitment
- Abstract:
- In an experiment we study the influence of prior outcomes on risky choice. We document a strong framing effect. By manipulating the presentation format of the decision problem we can induce increased risk taking following a gain, i.e. the house-money effect (Thaler and Johnson 1990) or, alternatively, increased risk taking following a loss, i.e. escalation of commitment (Staw 1976). Maximization of a value function from prospect theory can explain some of our results. Escalation of commitment in our experiment does not appear to be driven by a need to justify or rationalize the initial decision.
