摘要
While a substantial body of empirical research has focused on the pricing of green debt, there is no consensus on the existence of a green bond yield premium, or “greenium”. To elucidate the mechanism through which green bonds affect firms’ debt funding costs, this paper develops a dynamic capital structure model that incorporates green debt. Issuing green debt provides convenience for shareholders by lowering interest payments. However, it also lowers the firm’s expected growth rate, as proceeds are committed to green projects. Our model reveals that green debt refinancing causes shareholders to be conservative about debt policy, thus inducing the low target leverage level. The reduction in interest payments alleviate the debt burden, which reduces expected credit risk. As a result, creditors are willing to accept a low credit spread. Finally, we find that the degree of green investment and debt maturity have important effects on the greenium.
