Measuring the Impact of the BPDeepwater HorizonOil Spill on Consumer Behavior
利用BP深水地平线石油泄漏的时间点，收集泄漏前后牡蛎消费者的实际和预期行为数据，通过揭示偏好和陈述偏好模型分析短期和长期影响，发现泄漏短期内降低了需求，但几个月后影响减弱，且不同消费者群体反应不同。
We exploit the timing of the BP <i>Deepwater Horizon</i> oil spill to develop a unique dataset of oyster consumer actual and anticipated behavior immediately prior to and following the event. A revealed and stated preference model allows both short- and longer-term responses to the spill to be investigated. Findings indicate that the BP spill had a negative impact on oyster demand in terms of short-run actual behavior, although spill effects show signs of dissipating several months following the spill. By accounting for unobserved heterogeneity in the sample, findings further indicate that short- and longer-term spill responses differ across consumer groups. <i></i>
