Estimating the Ex Ante Recreational Loss of an Oil Spill Using Revealed and Stated Preference Data
结合揭示偏好和陈述偏好数据，估算挪威石油泄漏对休闲活动的事前福利损失，发现人均损失在347至524挪威克朗之间。
<h3>ABSTRACT</h3> This paper combines data to estimate the <i>ex-ante</i> recreational impact of oil spills. Using a unique contingent behavior question, our application highlights the gains in combining stated and revealed preferences. We consider both a reduction of the available choice set and of perceived site quality. We show that omitting perceived site quality leads to low welfare losses while omitting alternative specific constants leads to high welfare losses. Overall, we find recreational losses due to potential oil spills in Norway ranging from 347 and 524 NOK (32 to 49 US dollars) per person across the four oil spill scenarios.
