Firm characteristics, economic conditions and policy regimes are the key determinants that most researchers have used to explain corporate bond yield spreads. In this article, we examine whether monetary policy shocks are also important determinants given their ability to affect default risk, risk aversion and liquidity premiums. Using a Vector Autoregression (VAR) with long-run monetary neutrality, we find that monetary policy shocks do, in fact, account for a large portion of the variation in corporate bond yield spreads.
We apply an option-pricing framework to the ex-dividend behavior of common stocks. The framework explains the observed behavior of positive returns on the ex-dividend day and predicts that ex-dividend day returns will be higher for firms with greater financial leverage. Empirical testing supports the prediction. In contrast to prior studies, we find that dividendcapture activity has no significant impact on ex-dividend behavior, and we offer an explanation based on the importance of tick intervals.
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.
