There are two opposing research traditions in the history of economic thought on the subject of “banks and financial crises". The dominant view of financial intermediation and the “financial accelerator”theory introduces information asymmetries and explains banks and financial crises in a passive and exogenous way. This analytical paradigm was recognized by the 2022Nobel Memorial Prize in Economic Sciences. In fact, however, in the wake of the 2008 sub-prime crisis,mainstream economics uncharacteristically adopted the heterodox Minsky paradigm to repair its narrative framework. Based on fundamental uncertainty, Minsky proposed the “financial instability hypothesis”of an endogenous business cycle in terms of the credit creation theory of banking. The comparative study has shown that, despite substantial differences between the two analytical traditions on the behavioural theory of banking, theories of financial crises and business cycles, and a deeper view of the nature of money, the mainstream paradigm, which presupposes information asymmetries and the Minsky paradigm, which presupposes fundamental uncertainty, do not constitute an irreconcilable contradiction. On the one hand, the mainstream information approach has made the profound contribution to the field of banks and financial crises; on the other hand, Minsky's insights should also be appropriately drawn upon to complement and improve the mainstream research route, or even to provide a necessary synthesis of the two approaches.
