Understanding the Subprime Mortgage Crisis
利用贷款级数据，通过调整借款人特征、贷款特征和宏观经济条件来分析次贷质量，发现危机前六年贷款质量持续恶化，且证券化机构对此有一定了解。
Using loan-level data, we analyze the quality of subprime mortgage loans by adjusting their performance for differences in borrower characteristics, loan characteristics, and macroeconomic conditions. We find that the quality of loans deteriorated for six consecutive years before the crisis and that securitizers were, to some extent, aware of it. We provide evidence that the rise and fall of the subprime mortgage market follows a classic lending boom-bust scenario, in which unsustainable growth leads to the collapse of the market. Problems could have been detected long before the crisis, but they were masked by high house price appreciation between 2003 and 2005. The Author 2011.
