RECENT DEVELOPMENTS IN CONSUMER CREDIT AND DEFAULT LITERATURE

This survey discusses recent contributions to the quantitative literature on unsecured consumer debt and default, and some ongoing challenges for the literature. Key topics include the sources of the rise in personal bankruptcies, the importance of asymmetric information and the effects of developments in information technologies on consumer credit markets, delinquency and informal bankruptcy, debt collection and restructuring of distressed debt, the cyclical behavior of consumer debt and default, and the insurance role of household debt. Implications for welfare analysis and policy design are discussed. Several theoretical contributions and approaches to modeling the consumer credit markets are also highlighted.     

Credit lender–borrower relationship in the credit card market – Implications for credit risk management strategy and relationship marketing

Lehman Brothers filed for bankruptcy in 2008, precipitating the international financial crisis. Many questioned the banks’ risk-taking credit system. Understanding credit risk and how the credit system functions may provide knowledge on managing credit, to avoid another such international crisis. We study the credit card field and present a pricing decision model for managing credit risk. Recent credit lenders’ portfolio re-pricing practices call for immediate attention to the credit lender–borrower relationship and relationship marketing. A literature review and recent phenomena in the credit card industry reveal that the lenders’ re-pricing strategy negatively affects the credit lender–borrower relationship and relationship marketing. Thus, we introduce a pricing decision model incorporating the lenders’ re-pricing strategy and the credit lender–borrower relationship. Further, we discuss the implications of, and the role of marketing in, credit risk management and the implications of relationship marketing for credit lenders in foreign markets, including the US market.     

Factors affecting delinquency of household credit in the U.S.: Does consumer sentiment play a role?

In this study, we provide both theoretical and empirical evidence on the determinants of household loan delinquency for home ownership, credit card and auto loans for the U.S. states in a panel framework over a period from 2003 through 2017. In particular, we examine the impact of consumer sentiments on loan delinquency rates. We show that improved current consumer sentiment significantly induce lower mortgage, credit card and automobile loan defaults in the American states subdivided into four different regions. We also find that the higher overall and expected consumer sentiment raise loan delinquencies. Implicit in this finding is the apparently excessive and inappropriate expansion of loans in the U.S. economy in the face of consumers’ optimism, which in turn, provides an intuitive understanding of the circumstances that could precede a depression or outbreak of anomalies in the financial sector. Our general findings further exhibit significant positive effect of unemployment rate and mostly adverse effect of per capita income on mortgage and automobile loan delinquency rates. The results provide some compelling evidence with regard to the effect of consumer confidence on household credit delinquency rates across various states in the U.S. and are robust to alternative measures of income and mortgage rates.     

Delinquency and Default in Arms: The Effects of Protected Equity and Loss Aversion

This paper extends the extant literature in understanding the effects of equity and debt on delinquency and default by focusing on a variant of borrower equity where part of equity is “protected”. The CPF scheme in Singapore stipulates that the refund of borrower’s retirement funds utilized for property purchase prior to September 2002 takes priority over loan obligations. A decision to utilize CPF for property purchase actually increases ex post delinquency and default risk as it effectively reduces cash equity commitment. In particular, any erosion in house value that places protected equity at risk translates into potential wealth reduction or financial liability for the borrower. While loss aversion is evident for non-distressed sellers, the effect of equity losses for distressed borrowers is not as clear. Our research suggests that averting losses in committed equity may be a secondary consideration for borrower subject to income shocks, recognizing that delinquency and default are precursors to foreclosure. Interestingly, we find that the borrowers are strongly averse to incurring protected equity-induced wealth loss or financial liability. This study suggests that the first-lien “anomaly” associated with CPF refund may reduce delinquency and default risks for mortgage backed securities.

暴力资讯与未成年人犯罪实证研究——以社会学习理论为主要修正对象

以未成年人是否犯罪、未成年犯罪人是否实施暴力犯罪为因变量的对数回归模型显示,接触暴力资讯能增大未成年人犯罪的发生比却不能增大未成年犯罪人选择实施暴力犯罪的发生比。这表明,未成年人通过暴力资讯(符号示范)所习得的并非攻击性的行为方式本身,而是反规范的态度或行为倾向。回归模型还显示,在社会学习理论中居于重要地位的家庭示范和亚文化群示范在未成年人犯罪促成过程中的实际地位已让位于媒体,媒体暴力问题的严重性可见一斑。相应地,被普遍认为能够对暴力资讯促成未成年人犯罪作出合理解释的社会学习理论,亦当做出适当修正。     

个贷违约率与宏观经济指标相关性研究

本文将个人住房抵押贷款违约率作为因变量,选择可能对其有影响的主要宏观经济指标作为自变量,建立自变量与因变量之间的多元线性回归模型,运用1994～2009年第一季度间美国有关季度数据分阶段对该假设模型进行实证比较分析和检验,得出在不同宏观经济环境下各指标变量与个人住房抵押贷款违约率的影响关系,并尝试对与常理相矛盾的实证结果进行分析与解释。本研究对个人住房抵押贷款违约风险的管理及相关研究判断具有实证价值和现实意义。     

An empirical study on credit card loan delinquency

Following the Basel II convention, consumer credit default is commonly defined as delinquency beyond a period of 90 days. In this study, rather than considering default as a binary variable, we dissect delinquency states further to investigate default behavior in greater detail. As such, we define three states—no delinquency, delinquency and serious delinquency—and estimate the probabilities of the transitions between states using extensive panel data from Korea, covering a wide range of behavioral information. Our findings have several economic implications. First, the factors that affect delinquency risk can differ from those that affect the transition from delinquency to serious delinquency. Second, the recent increase in the number of seriously delinquent accounts can be attributed to changes in the borrower age distribution. Third, macroeconomic conditions, especially differences in gross domestic product and consumption growth, have led to the recent increase in delinquent accounts. Fourth, the debt-to-income (DTI) ratio has a profound effect on transitions between delinquency states and thus affects both recovery and delinquency. Furthermore, this result is robust to controls for demographic and macroeconomic factors.     

Trade credit and financial crises in Kazakhstan

This paper studies the trade credit and delinquency behavior in Kazakhstan paying attention to the effects of two recent crises using a unique dataset of large firms and SMEs from the year 2009 to 2016. Our estimates suggest that the relationship between trade and bank credit is mainly substitutional except that it was complementary for large firms following the year 2014–5 crisis. This new piece of evidence on the non-uniform relationship between trade and bank credit during crisis might provide more insight into the mixed findings in the literature. We also discern that trade credit demand is more prevalent among capital-intensive firms. Kazakhstani firms pass along a sizeable portion of their delinquent receivable to their trade credit suppliers. The transmission of trade credit delinquency, additionally, is amplified during the year 2014–5 economic crisis but the year 2009 global financial crisis.
