We suggest that an unexpected volatility shock is an important risk factor to induce the intertemporal relation, and the conflicting findings on the relation could be attributable to an omitting variable bias resulting from ignoring the effect of an unexpected volatility shock on the relation....

In this paper, we explore nonlinearity inherent in short-horizon return dynamics, which is characterized by an asymmetric mean-reverting property. Over the period of 1962:07–2003:12, both daily and weekly returns of three market indexes and individual stock returns exhibit a strong asymmetric...

Employing annual returns generated from overlapping monthly price indexes for the G-7 stock markets, this paper examines asymmetry and common nonlinearities in long-horizon stock returns. Identifying widespread nonlinearities based on LSTAR or ESTAR models, we find that the asymmetric nonlinear...

Using STAR models, we investigate the nonlinear dynamic properties and the interdependence of CO2 emissions and economic growth for Korea. The estimation results indicate that the growth rate of both CO2 emissions and industrial production exhibit a significant nonlinear asymmetric dynamics....
