An Interest Rate Adjusting Mechanism in Consideration of Payment Histories of Groups to which a borrower belongs in Social Lending
Masashi Iwakami, Takayuki Ito (Nagoya Institute of Tech.) AI2008-23
Abstract (in Japanese) (See Japanese page) 
(in English) In social lending, in which an individual lends or borrows money using an SNS network,
a person who lends money must take a risk that the money won't be returned.
Since social lending is a comparatively new field, the mechanism is designed experientially in many cases.
In this paper, we propose a mechanism to adjust an interest rate.
We present an experimental assessment of the influence
of the updating of an interest rate using Bayesian estimation,
which takes into consideration the payment history of groups with agents.
We discuss the influence on a payment delay rate by making a borrower belong to the group.
Our method decreases dispersions of the delay of the borrower in payment
with the increasing loan history of the borrower.
As a result, when the lenders are risk-averse, the number of transactions increases.
Therefore, our method is effective because it can cause the transactions of lenders who are risk-averse to increase.
