This paper investigates the impact of investor attention on oil market volatility, finding that changes in investor attention mainly affect bad volatility rather than good volatility, and can influence future oil prices. Moreover, economic policy uncertainty can enhance the positive relationship between investor attention and bad volatility.
This paper aims to investigate the impact of investor attention on the oil market volatility by using the Google search volume index as the measurement of investor attention. In particular, we decompose aggregate volatility into good volatility and bad volatility to gain a deeper insight into this issue. Additionally, we discuss whether the relationship between investor attention and oil market volatility changes with the adjustment of economic policy uncertainty in G7 and BRIC. The empirical results show that changes in investor attention mainly affect bad vol-atility rather than good volatility, and this impact is positive, symmetric, and transient. Interestingly, this impact can also lead to changes in future oil prices through the volatility feedback effect channel. Moreover, we find that the economic uncertainty policy can enhance the positive relationship between investor attention and bad vol-atility, but this relationship seems to be only sensitive to economic policy uncertainty in the US and Canada (c) 2021 Elsevier B.V.
