This article considers how the appropriate policy to promote defensible space should differ between wildland-urban interface (WUI) communities by analyzing the extent that the two prominent explanations for socially inefficient underinvestment in defensible space hold in 35 WUI communities in Nevada. We find that homeowners underinvest in defensible space due to externalities in communities whose predominant vegetation is associated with elevated wildfire hazard. We do not find evidence that homeowners are underinvesting in defensible space because they systematically misjudge the biophysical determinants of their wildfire risk or the efficacy of defensible space at reducing their wildfire risk.

旨在促进荒地 - 城市界面中的防御空间的针对性政策：来自内华达州房主的证据

本文通过分析内华达州 35 个 WUI 社区对可防御空间的社会效率低下投资不足的两种突出解释的程度，考虑了促进可防御空间的适当政策应如何在荒地 - 城市界面 (WUI) 社区之间有所不同。我们发现，由于主要植被与野火风险升高相关的社区的外部性，房主对防御空间的投资不足。我们没有发现证据表明房主对可防御空间投资不足，因为他们系统地错误判断了决定其野火风险的生物物理决定因素或可防御空间在降低野火风险方面的功效。(JEL D81, Q54)
