Local land use regulations and new mobile home concentration
利用美国城市和县的数据，研究地方土地使用法规如何影响新活动房屋在所有新建住房中的占比，发现对活动房屋的限制和城市增长边界都会降低其集中度，且考虑内生性后影响更大。
Mobile homes can be produced in high volumes at a lower cost than traditional stick-built single-family dwellings but face regulatory, financial, and perceptual barriers to more widespread market penetration. This research relies on data from a sample of US cities and counties to examine the influence of local land use regulations on the concentration of new mobile homes among all new homes added over two 10-year time spans. In contrast to previous studies, this study relies on a nationwide sample of jurisdictions, employs more precise measures of mobile home placements and local land use regulations, and addresses the endogeneity of mobile home restrictions. I find that regulatory restrictions on mobile homes and urban containment boundaries both limit the concentration of new mobile homes. Furthermore, the impact of mobile home restrictions is much larger when accounting for the endogeneity of mobile home restrictions. These findings suggest that land use regulatory reform can play an important role in local affordable housing strategies geared towards expanding the supply of mobile homes.
