摘要:本研究探讨借款人自我叙述借贷条件如何影响借款人对无担保个人贷款的决策。具体来说, 借贷条件的描述数量和其内容影响贷款的决定,它们能预测贷款的长期信用吗?使用P2P借贷网站Prosper.com的数据,作者发现无法核实的信息对贷款决策的影响超越客观、可核实的信息对其的影响。随着要求叙述的借贷条件要求数量的增加, 贷款资金也是如此。反之当贷款信用受到损害时,因为这些借款人偿还贷款的可能性较小。此外,描述内容起着重要的作用。值得信赖的身份声明与增加贷款资金有密切关系,但具有讽刺意味的是预测贷款的表现不如其他身份(即道德和经济困难)。因此,一些身份声明旨在误导贷款人,而另一些人提供借款人的真实情况。

四、研究

(一)数据

我们的数据包括从2006年6月和2007年6月在Prosper平台发布的借款人贷款清单1493条。我们使用分层随机抽样策略提取了这个数据集。 通过使用网络爬虫,我们提取了2006年6月和2007年6月发布的所有贷款清单(分别约为5,400和12,500个清单)。 Prosper的很大一部分借款人的信用历史很差,大多数贷款申请都没有获得资金。为避免高风险借款人和无资金贷款占比过重,我们从每个信用分级中抽取了相同数量的贷款申请。为此,我们首先将没有资金的贷款请求分开,然后按Prosper分配的七个信用等级划分每个组。 我们还取消了所有没有任何叙述性文字的贷款申请,原因有三。首先,包括没有叙述的贷款请求可能会混淆借款人选择在公开文本框中写入除叙述之外的东西以及选择不写任何内容。其次,绝大多数缺乏叙述的列表都没有获得资金。 第三,没有文本的贷款申请只占2006年6月发布的所有贷款的9%,2007年6月发布的贷款的4%。然而我们仍然在我们的健全性检查中使用“无文本”贷款。

我们随机抽样了14个小组的申请(2个资助状态times;7个信用等级)。2006年,我们从每个分组中抽取了40个列表(直到数据用尽),以获得513个列表; 在2007年,我们从每个小组中抽取了70个列表,以获得980个列表,共计1,493个列表。 每个列表包括借款人的信用等级,申请贷款金额,最高利率,贷款资金,资金贷款的最终利率,两年后资金贷款的投资回收情况以及开放式文本数据。 在结合2006年和2007年的数据之前,我们测试了一年的效果,但没有任何发现,这支持了它们的组合。

(五)结果与结论

根据H1[1],我们断定,信用等级较低的结果更多的是借款人对自己的借贷条件叙述的项目增多。我们采用趋势分析来测试这一假说;道斯和科里根(1974)表明,线性函数可以在任何有条件的单调关系中表示几乎所有的变量。因此我们把信用等级信息作为一个变量,用下面的可能值:1如果信贷等级是人力资源,2=E,3=D,4=C,5=B,6=A,7=AA。我们使用了将这个变量视为分类的协方差分析。当我们控制人口和贷款特征变量,进行趋势分析,正如我们所预期的, 在借款人的信用评分和借款人对自己的借贷条件叙述的项目的数量之间显示出了显著的线性关系,(t(1472)=2.63,plt;.01)。在借贷条件叙述的项目的数量上,高阶多项式趋势并不占很大比例的方差(P二次=.17,P立方=.81,P四次方=.16)。在图1中,我们提供了描述身份项目的数量估计边际均值作为信用等级的函数,用于控制人口和贷款特征。

注:这些值是在控制了人口统计和贷款金融特征之后的。协方差的评估值如下:申请贷款金额= 8310.24,初始利率=.169081,男性=.32,女性=.24,已婚=.23,,离异=.04,单身=.05,订婚=.03,白种人=.35,非裔美国人=.07,西班牙裔=.01,孩子=.27。

根据H2a[2],我们假设更多的身份描述将对获得贷款资金有积极的影响。为了验证这个假设,我们将描述身份的项目数量作为主要预测指标和信用等级,申请金额、性别、婚姻状况、种族、家庭状况作为在贷款资金的自然对数上的协变量进行回归。我们目前的结果在表3中。

Tell Me a Good Story and I May Lend You

Money: The Role of Narratives in

Peer-to-Peer Lending Decision

Abstract

This research examines how identity claims constructed in narratives by borrowers influence lender decisions about unsecured personal loans. Specifically, do the number of identity claims and their content influence lending decisions, and can they predict the longer-term performance of funded loans? Using data from the peer-to-peer lending website Prosper.com, the authors find that unverifiable information affects lending decisions above and beyond the influence of objective, verifiable information. As the number of identity claims in narratives increases, so does loan funding, whereas loan performance suffers, because these borrowers are less likely to pay back the loan. In addition, identity content plays an important role. Identities focused on being trustworthy or successful are associated with increased loan funding but ironically are less predictive of loan performance than other identities (i.e., moral and economic hardship). Thus, some identity claims aim to mislead lenders, whereas others provide true representations of borrowers.

STUDY

Data

Our data set consists of 1,493 loan listings posted by borrowers on Prosper in June 2006 and June 2007. We extracted this data set using a stratified random sampling strategy. Using a web crawler, we extracted all loan listings posted in June 2006 and June 2007 (approximately 5,400 and 12,500 listings, respectively). A significant percentage of borrowers on Prosper have very poor credit histories, and most loan requests do not receive funding. To avoid overweighting high-risk borrowers and unfunded loans, we sampled an equal number of loan requests from each credit

grade. To do so, we first separated funded loan requests from unfunded ones, then divided each group by the seven credit grades assigned by Prosper. We also eliminated all loan requests without any narrative text, for three reasons.First, including loan requests without narratives could confound the borrowers choice to write something other than narratives in the open text box with the choice to write nothing at all. Second, the vast majority of listings lacking a narrative do not receive funding. Third, loan requests without text represent only 9% of all loans posted in June 2006 and 4% of those posted in June 2007. We nevertheless used the 'no text' loans in our robustness check.

We randomly sampled posts from the 14 subgroups (2 funding status x 7 credit grades). In 2006, we sampled 40 listings from each subgroup (until data were exhausted) to obtain 513 listings; in 2007, we sampled 70 listings from each subgroup to obtain 980 listings, for a total of 1,493 listings. Each listing includes the borrowers credit grade, requested loan amount, maximum interest rate, loan funding, final interest rate of funded loans, payback status of funded loans after two years, and open-ended text data. Before combining the data from 2006 and 2007, we tested for a year effect but found none, which supports their combination.

Results and Discussion

In H1 we posited that a lower credit grade would result in more identities claimed in a borrowers narrative. We employed a trend analysis to test this hypothesis; as Dawes and Corrigan (1974) suggest, a linear function can account for almost all the variance in any conditionally monotonic relationship. Thus we coded the credit grade information as one variable, with the following possible values: 1 if the credit grade is HR, 2 = E, 3 = D, 4 = C, 5 = B, 6 = A, and 7 = AA. We employed an analysis of covariance that treats this variable as categorical. When we control for demographic and loan characteristic variables, the trend analysis, as we expected, showed a significant linear relation between borrowers credit score and the number of identities that borrowers constructed in their narratives (t(1472) = 2.63, p lt; .01). Higher-order polynomial trends did not account for a significant proportion of the variance in the number of identities (pquadratic = .17, Pcubic = .81, Porder4 = .16). In Figure 1, we provide the estimated marginal means of the number of identities as a function of credit grade, controlling for demographics and loan characteristics.

notes: These values are after controlling for demographics and loan financial characteristics. Covariates are evaluated at the following values: requested loan amount=8,310.24, initial interest rate=.169081, male=.32,female=.24, married=.23, divorced=.04, single=.05, engaged =.03, Caucasian =.35, African American=.07, Hispanic=.01, children=.27.

In H2a, we posited that more identities claimed in a narrative would have a positive effect on loan funding. To test this hypothesis, we regressed the number of identities as the main predictor and credit grade, requested amount, gender, marital status, race, and family status as covariates on the natural log of loan funding. We present the results in Table 3,

notes: Regarding the reference categories for the predictors, for gender, it is “no gender”(borrowers did not disclose their gender);for marital status, it is 'no marital status or widow' (only two widows in the sample); for race, it is 'no race or race other than Caucasian, African American, or Hispanic' (i.e., there were a few Asian and Indian respondents); and for credit grade, it is HR (high risk).

which shows that when we control for borrowers demographics and loan characteristics, the number of identities borrowers clai
