This study examines the association between mandatory financial reporting frequency and the accrual anomaly. Based on regulatory changes in reporting frequency requirements in Taiwan, we divide our sample period into three reporting regimes: a semiannual reporting regime from 1982 to 1985, a quarterly reporting regime from 1986 to 1987, and a monthly reporting regime (both quarterly financial reports and monthly revenue disclosure) from 1988 to 1993. We find that although both switches (from the semiannual reporting regime to the quarterly reporting regime and from the quarterly reporting regime to the monthly reporting regime) hasten the dissemination of the information contained in annual accruals into stock prices and reduce annual accrual mispricing, the switch to monthly reporting has a lesser effect. Our results are robust to controlling for risk factors, transaction costs, and potential changes in accrual, cash flow persistence, and sample composition over time. These results imply that more frequent reporting is one possible mechanism to reduce accrual mispricing.
