Financial crisis and changes in determinants of risk and return: an empirical investigation of an emerging market (ISE)

Abstract

This paper examines how determinants of volatility and stock returns change with financial crisis. The contributions of the paper are twofold. First, using a GARCH-M framework, risk and return are jointly modeled by using macroeconomic variables both in the variance and the mean equations. The conditional variance equation is specified by including macro-economic variables, a relevant information set for emerging economies, that is often overlooked in various GARCH specifications. Second, determinants of risk and return are investigated before during and after a major financial crisis at ISE. We show that, both the determinants of risk and the risk-return relationship change as the economy switches from one regime to the other.
