This paper studies housing market outcomes of undocumented immigrants in the U.S. and explores the mechanisms behind the differential prices that immigrants pay for shelter. I show that undocumented renters pay a premium for housing relative to observably similar, documented, immigrant renters occupying similar housing. Building on theory and suggestive evidence that the premium is the result of search frictions driven by fear of deportation, I employ a triple-differences strategy to evaluate the impacts of sanctuary city policies on housing market outcomes of undocumented immigrants. I find that sanctuary city policies, which limit immigration enforcement, reduce housing costs of undocumented renters, suggesting such policies mitigate search frictions for this group.

寻求庇护：为无证移民提供住房

本文研究了美国无证移民的住房市场结果，并探讨了移民为住房支付的差异价格背后的机制。我发现，相对于明显相似、有证件的、居住类似住房的移民租房者，无证租房者支付的住房溢价更高。基于理论和暗示性证据表明溢价是由于担心被驱逐而导致的搜索摩擦的结果，我采用三重差异策略来评估庇护城市政策对无证移民住房市场结果的影响。我发现限制移民执法的庇护城市政策降低了无证租房者的住房成本，这表明此类政策减轻了该群体的搜索摩擦。
