Although psychometric features have been considered for alternative credit scoring, they have not yet been applied to peer-to-peer (P2P) lending because such information is not available on platforms. This study proposed an alternative credit scoring model for P2P lending by extracting typical personality types inferred from the borrowers' job category. We projected a virtual space of borrowers by using the affinity matrix based on the Myers-Briggs type indicator (MBTI) that fits each job category. Applying the distance in this space to Lending Club data, we used locally weighted logistic regression to vary the coefficients of the variables, which affect loan repayments, with each MBTI type for predicting the default probability. We found that each MBTI type's credit scoring model has different significant variables. This study provides insights into breakthroughs in developing alternative credit scoring for P2P lending.

尽管心理测量特征已被考虑用于替代信用评分,但它们尚未应用于点对点(P2P)借贷,因为此类信息在平台上不可用。本研究通过提取从借款人职业类别推断出的典型性格类型,提出了一种用于P2P借贷的替代信用评分模型。我们基于适合每个职业类别的迈尔斯-布里格斯性格分类指标(MBTI),使用亲和矩阵来投射借款人的虚拟空间。将此空间中的距离应用于Lending Club数据,我们使用局部加权逻辑回归来根据每种MBTI类型改变影响贷款偿还的变量系数,以预测违约概率。我们发现每种MBTI类型的信用评分模型具有不同的显著变量。本研究为P2P借贷替代信用评分的发展突破提供了见解。
