We employ a rational expectations framework similar to that proposed by Fleming et al. (1998) to examine the source, and nature of, information linkages between the emission allowance and energy markets as gauged by the correlation of return volatilities. Estimating the model for bivariate pairings of securities suggests that market linkages arise from sensitivities to common information rather than from indirect spillovers, with emission allowances most strongly linked to the crude oil market.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
