Why renters choose to move likely plays a role in whether the outcomes of their mobility will be positive (e.g. labor market efficiency) or negative (e.g. lower student achievement). If we can determine why renters move, lawmakers can design housing policies to foster positive mobility and reduce negative mobility. The purpose of this paper is to build on prior models of renter mobility to develop a conceptual model that can be mapped to the various effects of mobility. Within the model, I identify reasons for (im)mobility that may be receptive to housing policy intervention. As an illustration of the model, I use a difference-in-difference-in-difference (DDD) model and data from the 1981–2014 March supplements of the Current Population Survey (IPUMS-CPS) to show how various landlord-tenant policies impact the frequency of renter mobility. I use the conceptual model to hypothesize the nature of the relationship between public policy and mobility. Results indicate policies regulating late fees and self-help remedies play a role in reducing renter mobility. While all policies tested here do not have a significant effect on renter mobility, the impact of some policies highlights the need for targeted, evidence-driven interventions.

房客选择搬家的原因可能会影响其迁移的结果是积极的（例如，劳动力市场效率）还是消极​​的（例如，较低的学生成绩）。如果我们能确定为什么租客迁徙，立法者可以制定住房政策以促进积极的迁徙并减少负的迁徙。本文的目的是在先行的租房者流动模型的基础上，开发出可以映射到流动性的各种影响的概念模型。在模型中，我确定了可能导致住房政策干预的不流动原因。作为该模型的说明，我使用了DDD模型和1981-2014年3月当前人口调查补充数据（IPUMS-CPS）中的数据，以显示各种房客租赁政策影响租户流动的频率。我使用概念模型来假设公共政策与流动性之间关系的性质。结果表明，规范滞纳金和自助措施的政策在减少房客流动方面发挥了作用。尽管此处测试的所有政策对租房者的流动性没有显着影响，但一些政策的影响凸显了针对性的，循证驱动的干预措施的必要性。
