Retesting the institutional memory hypothesis: An experimental study

Abstract

In this article, we set ourselves a task to test institutional memory hypothesis as a core of endogenous credit cycles. According to this hypothesis, risks taken by creditors depend largely on availability heuristic and experience of loan officers. To assess validity of this hypothesis we construct and estimate a simple VAR model. The data for this model is acquired from results of an experimental study (lasted for 70 rounds), the purpose of which is to identify behavioral patterns of participants while meeting demand for credit, specifics of subjectively weighted assessment of credit risk, based on shock approach. The results of the study allow confirming institutional memory hypothesis. After initial shock of bad debts, number of periods to recover willingness to accept risk has increased by 39%, which supports the hypothesis of availability heuristic’s influence. However, with improvement of loan portfolio’s quality, willingness to take risk is restoring. In addition, we managed to confirm existence of risk’s underestimation and overestimation periods in an experimental manner.
