The objective of this research is to examine the effect of internal control to earnings quality. We examine the effect of corporate culture as a moderating variable to the effect of internal control to earnings quality. The internal control will be measured with five elements of internal control based on COSO?s illustrative tools. Text analysis is a method that used to measure corporate culture based on four cultures dimension by Cameron et al. (2006) with bag of words by Fiordelisi and Ricci (2014). Based on 188 companies that are listed in Indonesia`s Stock Exchange (BEI) from 2011 to 2013 (564 observations), the empirical study with panel data regression shows that the effectivity of internal control can increase the earnings quality. The hierarchy culture (control-oriented) can moderate the effectivity of internal control to earnings quality.
