Empirical researches provide varied results on the effect of audit committee size on earnings
management. The findings of the meta-analysis reported in Table 3 illustrate a significant
negative association (at the 1% level for the unweighted and 5% level for the weighted test)
between audit committee size and earnings management. The fail-safe number also
substantially exceeds the critical number of studies (934 versus 421), supporting the
importance of having large audit committee.
