Finally, I perform a pooled regression of price on the book value and net income per share. This
includes an accounting standard dummy variable and its product with book value and net income in
order to check the differential effect of reporting under IFRS on Italian GAAP (Bartov et al. 2005,
Horton and Serafeim 2010). Results (not reported) are qualitatively similar to previous findings, as
both the dummy variable and the interaction terms are not statistically significant, indicating that
reporting under IFRS does not provide incremental value-relevance for accounting numbers.
