The Moderating Role of Reporting Quality

Abstract

This paper examines whether municipal market participants' sensitivity to signals about the local economy varies with the quality of local governments' historical financial reports. We find the credit ratings and bond yields of governments that are required to comply with Generally Accepted Accounting Principles (GAAP) are less sensitive to changes in local home values than similarly affected governments that are not required to comply with GAAP. To attribute these results to reporting quality, we confirm in a difference-in-differences analysis that GAAP's moderating role increased after the adoption of GASB 34, which substantially improved the quality of GAAP compliant issuers' financial reports. To understand the mechanism, we study positive and negative economic signals separately. Consistent with reporting quality decreasing market participants' uncertainty about issuers' pre-existing likelihood of default, the results are pronounced when the change in home values generates the most uncertainty (i.e., when the change is adverse). We conclude that market participants are less sensitive to local economic signals when the government's historical financial reports are of higher quality.
