The market impact of mandatory interactive data : evidence from bank regulatory XBRL filings / Lizhong Hao, Mark J. Kohlbeck - 2013. - Journal of Emerging Technologies in Accounting 10, page 41-62 .
We investigate the market impact of banks filing regulatory reports using eXtensible Business Reporting Language (XBRL) interactive data format. Specifically, we examine whether stock returns and trading volume exhibit abnormal behavior when banks are first required to file Call Reports in XBRL format and whether XBRL adoption causes a shift in systematic risk. We find that banks experienced significant positive abnormal returns and a subsequent reduction in systematic risk in connection with filing their regulatory reports in XBRL. Our results are more pronounced for larger banks. Our trading volume analysis provides additional support of increases in trading volume (primarily with respect to larger banks) at the time of XBRL adoption. We, therefore, document investor-based benefits in support of the conversion to mandatory XBRL filing requirements.
