英文摘要:
Many households in developing countries lack formal financial histories, making it difficult for firms to extend credit, and for potential borrowers to receive it. However, many of these households have mobile phones, which generate rich data about behavior. This article shows that behavioral signatures in mobile phone data predict default, using call records matched to repayment outcomes for credit extended by a South American telecom. On a sample of individuals with (thin) financial histories, our method actually outperforms models using credit bureau information, both within time and when tested on a different time period. But our method also attains similar performance on those without financial histories, who cannot be scored using traditional methods. Individuals in the highest quintile of risk by our measure are 2.8 times more likely to default than those in the lowest quintile. The method forms the basis for new forms of credit that reach the unbanked.

中文摘要:
发展中国家的许多家庭缺乏正式的财务记录,这使得企业难以发放信贷,潜在借款人也难以获得信贷。然而,其中许多家庭都有手机,手机可以生成丰富的行为数据。这篇文章表明,手机数据中的行为签名可以预测违约,使用的通话记录与南美电信公司发放的信贷的还款结果相匹配。在有(薄)财务历史的个人样本上,我们的方法实际上优于使用信贷局信息的模型,无论是在时间内还是在不同时间段测试时。但我们的方法在那些没有财务历史的人身上也取得了类似的效果,这些人无法使用传统方法进行评分。根据我们的衡量,风险最高五分之一的个人违约的可能性是最低五分之一个人的2.8倍。该方法为新的信贷形式奠定了基础,这些新形式的信贷可以惠及非银行客户。
