The Shelf Registration of Debt and Self Selection Bias
以往研究认为货架注册能降低债务发行成本，但本文发现这种成本节约源于自选择偏差，而非注册方法本身。
ABSTRACT Prior studies report lower issue costs for shelf registered debt and conclude that the benefits of increased underwriter competition can be realized by those firms using this registration procedure. This study re‐examines the purported superiority of issuing debt via shelf registration, and finds that the savings in issue costs displayed by earlier studies can be attributed to a self selection bias and not the method of registration.
