Abstract

the objective of this paper is to analyze the imprints of standard finance and behavioral finance on Securities Market Supervision (SMS) policies before the 2008 Global Financial Crisis (GFC) and to discuss the question why the SMS policies should adopt behavioral finance as a response to issues identified from the crisis. Standard finance has been the most influential theoretical underpinning for securities market supervision before the 2008 GFC. The philosophy of securities market supervision has for long time relied on the notions of Efficient Market Hypothesis (EMH) and Capital Asset Pricing Model (CAPM). Relying on standard finance, securities regulators believed that market is efficient and investors are rational. Therefore securities markets were let to regulate themselves. Emerging behavioral finance provided a different insight, which argues that market is not efficient and investors are bias due to their cognitive errors. The debate between two economic theories seemed endless. However, the 2008 GFC made securities regulators and economists rethink their conceptual framework of market supervision. A supervisory philosophy based more on behavioral finance may be an option for the development of policies for market regulation and supervision in post-crisis economic and political environment.
