美次贷危机对推进我国住房抵押贷款证券化的启示

从证券化视角看,金融资本持续的流动性过剩,美联储的货币政策调整,衍生品市场链条过长,以及次级债的风险管理缺失等,共同造就了次级债危机。这对推进我们抵押贷款证券化发展,在金融机构、资本管理、政府监管等多方面提供了教训和启示。

资产证券化中信用评级机构道德风险研究——基于演化博弈分析

首先针对信用评级机构在资产证券化中的重要作用,分析了信用评级机构道德风险对资产证券化产生的不良影响,并由此论述了信用评级机构的道德风险产生原因;其次通过构建信用评级机构博弈支付矩阵,运用演化博弈论对评级机构的演化趋势做出分析,得到其演化的三种不同的稳定策略;最后从建立声誉机制、保证评级机构独立性、加强监管力度三个方面给出政策建议。

Emergence of subprime lending in minority neighborhoods

Subprime lending is concentrated in minority neighborhoods. However, the literature provides little evidence for what led to this concentration. We use the endorsement of credit scores in mortgage underwriting by the Government Sponsored Enterprises (GSEs) in 1995 to answer this question. We show that prime lenders were substituted by subprime lenders in minority neighborhoods. As a result, the share of subprime lending increased by 5 percentage points in minority neighborhoods, relative to nonminority neighborhoods. Prime lenders with a stronger relationship with the GSEs reduced their lending in minority neighborhoods more, and the level of securitization by the GSEs in minority neighborhoods also decreased.     

Are covered bonds different from securitization bonds? A comparative analysis of credit spreads

This study compares credit spreads and pricing determinants of securitization vis-à-vis covered bonds. Our analysis reveals that although ratings are the most important pricing determinant for asset-backed securities (ABS) and mortgage-backed securities (MBS) investors place relatively more importance on contractual, macroeconomic and banks' characteristics rather than ratings in pricing covered bonds. We find evidence of a mispricing effect in structured finance markets: ABS and MBS have higher credit spreads than similarly rated public-covered bonds and mortgage-covered bonds and security prices reflect information beyond credit ratings. We find no evidence of borrowing costs affecting banks' choice between securitization and covered bonds.     

Lenders’ pricing strategy: Do neighborhood risks matter?

This article explores the different pricing strategies of lenders who originate both government-sponsored enterprise (GSE) and non-GSE loans. We find that conditional on loan and borrower characteristics and some observable local economic factors, mortgage rates on GSE loans vary significantly across regions. However, we observe no sizable regional variation in loan amounts or default risk. By contrast, the mortgage rates on non-GSE loans depend almost entirely on borrowers and loan characteristics. In addition, we find that spatial variations in GSE mortgage rates are highly responsive to regional prepayment risk. Our results are robust to various controls for neighborhood characteristics, including regional-level bank competition, borrower accessibility to mortgages, and household income levels. Overall, the findings offer a novel insight into how lenders adjust pricing strategies in response to a changing lending environment. The results provide implications relating to the present and imminent dangers of housing bubbles and the intensified refinancing wave following the COVID-19 pandemic.
