This paper examines simultaneously the effect of E. coli and harmful algal blooms on recreational behavior using survey data collected from Ohio recreators who visited Lake Erie during the summer of 2016. Using simulation based on latent class models of recreation choice, we find beachgoers and recreational anglers would lose in aggregate $7.7 million and $69.1 million, respectively, each year if water quality conditions were to become so poor that Lake Erie’s western basin were closed. Finally, we recover heterogeneity in recreators’ aversion toward algae and Escherichia coli, with beachgoers more averse to E. coli and anglers more averse to algae. (JEL Q51, Q53)

有害藻华和大肠杆菌对伊利湖休闲行为的影响

本文使用从 2016 年夏天访问伊利湖的俄亥俄州游乐者收集的调查数据，同时检查了大肠杆菌和有害藻华对游乐行为的影响。 使用基于游憩选择的潜在类模型的模拟，我们发现了海滩游客和游乐者如果水质状况恶化到伊利湖西部盆地被关闭，垂钓者每年将分别损失 770 万美元和 6910 万美元。最后，我们恢复了娱乐者对藻类和大肠杆菌的厌恶的异质性，海滩游客更厌恶大肠杆菌，垂钓者更厌恶藻类。(JEL Q51, Q53)
