Note: This table presents the OLS regression results in Big 4 sample. Since Big 4 are more likely to be
identified as experts based on dummy variables (
IMS_D
and
IPS_D
equal 1 in most of Big 4
sample observations), we only use continuous variables (
IMS
and
IPS
) to proxy industry
expertise. The sample includes 455 firm-year observations for the period 2008-2012. T-statistics
are in the parentheses. ***, **, * stand for a statistical significant level of 1%, 5%, and 10%
respectively.
