Abstract:This paper examines the role of credit rating changes on municipalities’ disclosure decisions. Using Moody’s recalibration of their municipal ratings scale in 2010 as an exogenous upgrade to municipal credit ratings, we find that upgraded municipalities significantly reduced their disclosure of financial information relative to unaffected municipalities. Consistent with rating upgrades decreasing municipal issuers’ cost of capital and reducing investors’ demand for disclosure, we find that this reduction is greater for issuers with greater ex–ante information asymmetry, greater ex–ante investor reliance on disclosure, and lower monitoring by underwriters and auditors. Collectively, our results suggest that higher ratings can reduce the transparency of debt issuers’ information environments by reducing borrowers’ incentives to disclose financial information.
