This article examines the question: Does regulatory approval of prospectuses act as a “certification” of securities offerings? Rational investors should generally ignore prospectus approval due to its being uninformative regarding either the quality of, or motives for, the underlying offering. Our survey experiment demonstrates that salient references to regulatory oversight in investment advertisements can lead to significant increases in willingness to invest and concomitant decreases in perceived risks. Conversely, salient disclosure of risk factor information increases risk perceptions and reduces the intention to search for additional information. Various robustness tests confirm that investors can perceive regulatory oversight of securities offerings as an endorsement. Our results provide insight regarding the design of the disclosure and the effective regulation of financial marketing.
