有几个事实促使了这项研究。首先，发展中国家的生活容易面临多种风险，如自然灾害（天气、虫害和火灾）和国内冲突造成的作物和收入损失。第二，国际移民和汇款流动规模庞大，而且还在不断增长。从1965年到2000年，生活在国外的人占世界人口的比例从2.2%增长到2.9%，2000年达到1.75亿人。这些移民寄回原籍国的汇款是一种重要但鲜为人知的国际金融流动。本文探讨了一种应对事后冲击的机制，这是以前微观层面的研究没有关注的：海外家庭成员的汇款。在国际层面，通常假设来自海外的汇款流缓冲了移民母国的经济冲击，但用微观层面的家庭数据对这一说法进行的实证检验相对较少。卢卡斯和斯塔克（1985）、罗森茨威格和斯塔克（1989）以及保尔森（2000）对国内移民在大家庭内分担风险中的作用进行了相关研究。
Several facts motivate this study. First, life in developing countries is prone to many kinds of risk, such as crop and income loss due to natural disasters (weather, insect infestations, and fire) and civil conflict. Second, international migration and remittance flows are substantial and growing. Between 1965 and 2000, individuals living outside their country of birth grew from 2.2 to 2.9 percent of the world population, totaling 175 million people in 2000. The remittances that these migrants send to their countries of origin are an important but poorly understood type of international financial flow. This article examines a mechanism for coping with shocks ex post on which previous micro-level studies have not focused: remittances from family members overseas. At the international level, it is commonly posited that remittance flows from overseas buffer economic shocks in migrants' home countries, but there have been relatively few empirical tests of this claim with micro-level household data. Related research on the role of domestic migration in pooling risk within extended families includes Lucas and Stark (1985), Rosenzweig and Stark (1989), and Paulson (2000).
