报告内容摘要

  

The eXtensible Business Reporting Language (XBRL) is an open standard that aims to facilitate the preparation, exchange, and comparison of financial reports. Leveraging the opportunity created by the exogenous XBRL adoption mandated by the U.S. Securities and Exchange Commission, we use a difference-in-differences (DID) research design to identify the causal effect of XBRL adoption on readability of HTML-formatted financial reports, an important source of financial information for investors and analysts. We find that mandatory XBRL adoption has made adopting firms’ HTML-formatted financial reports more complex and harder to read. Further analysis shows that this undesirable effect is more pronounced for firms with more quantitative disclosure.

  

If time permits, examples of tapping into various forms of data for finance and accounting research will be discussed: (1) Inferring firm industry group from the usage pattern of XBRL tags; (2) Discovering topics of comment letters in FASB’s standard-setting process; (3) Employee integrity and corporate information quality.
