Dear Statalist,
I am having difficulty interpreting the results from OSL regression. I
am trying to see whether Overconfident managers manipulate earnings in
a certain context.
The dependent variable earnings_Mgt is continuous The problem is that
the indicator variable for overconfidence (OC_D) is negative and
significant, while the interaction between the indicator variable and
market_value variable (OC_MV) is positive and significant. What does
that mean?
Does it mean that overconfident managers manipulate earnings less than
others (rational managers), but when the market value is high they
manipulate earnings more than rational managers do?
Your help is highly appreciated,
many thanks
Nahla Betelmal
