| dc.description.abstract | We investigate the fltering problem where the borrower’s time varying credit quality process is estimated using continuous time
observation process and her (in this paper we refer to the borrower as female and the lender as male) ego-network data. Te hidden
credit quality is modeled as a hidden Gaussian mean-reverting process whilst the social network is modeled as a continuous time
latent space network model. At discrete times, the network data provides unbiased estimates of the current credit state of the
borrower and her ego-network. Combining the continuous time observed behavioral data and network information, we provide
flter equations for the hidden credit quality and show how the network information reduces information asymmetry between the
borrower and the lender. Further, we consider the case when the network information arrival times are random and solve stochastic
optimal control problem for a lender having linear quadratic utility function. | en_US |
