The paper reviews 59 empirical studies that estimated the economic impact of forced displacement on host communities. A review of the empirical models used by these studies and a meta-analysis of 972 separate results collected from these studies are the main contributions of the paper. Coverage extends to 19 major forced displacement crises that occurred between 1922 and 2018, to host countries at different levels of economic development and different types of forced migrants. Results refer to outcomes related to employment, wages, prices and household well-being. All studies can be classified as ex-post quasi-natural experiments. The analysis on empirical modeling shows a preference for partial equilibrium modeling, differences-in-differences evaluation methods, and cross-section econometrics, with all these choices largely dependent on the type of data available. The meta-analysis finds that most results on employment and wages are non-significant. When significant, decreases in employment and wages are more likely to occur than increases with decreases strongly associated with the short-term, middle-income countries, females, young and informal workers. Food and rent prices tend to increase in the short-term but other prices may decrease. The probability of observing a decrease in household well-being among hosts is lower than 1 in 5.

本文回顾了59项实证研究，这些研究估计了强迫流离失所对东道社区的经济影响。这些研究使用的经验模型的综述以及对这些研究收集的972个独立结果的荟萃分析是本文的主要贡献。涵盖范围扩展到1922年至2018年之间发生的19次重大强迫流离失所危机，使经济发展水平不同和强迫移民类型不同的东道国成为可能。结果是指与就业，工资，价格和家庭福祉相关的结果。所有研究都可以归类为事后准自然实验。对经验建模的分析表明，偏向于部分均衡建模，差异差异评估方法和横截面计量经济学，所有这些选择在很大程度上取决于可用数据的类型。荟萃分析发现，大多数关于就业和工资的结果都不重要。显着的是，与短期内，中等收入国家，女性，青年和非正式工人密切相关的就业和工资下降比上升与下降的可能性更大。粮食和租金价格在短期内趋于上涨，但其他价格可能会下降。在寄宿家庭中观察到家庭幸福感下降的可能性低于五分之一。青年工人和非正式工人。粮食和租金价格在短期内趋于上涨，但其他价格可能会下降。在寄宿家庭中观察到家庭幸福感下降的可能性低于五分之一。青年工人和非正式工人。粮食和租金价格在短期内趋于上涨，但其他价格可能会下降。在寄宿家庭中观察到家庭幸福感下降的可能性低于五分之一。
