The contribution of the research to the literature rests on the evidence grounded on longterm
informational disruption in the overall adoption of IFRS, although support for the
informational benefit still requires targeted tests for that purpose. Furthermore, the applicationof the method – innovative in the field of accounting – with time series controlled by
economic factors enable the separation of accounting informational effects from the effects of
the facts acknowledged by accounting. The use of such a technique evaluating estimates of
variables that have suffered some temporal cutting may be applied to examine and validate
the quality of analysts’ projections, both for the market as internally for companies. We
suggest, in this regard, future studies using non-linear models (NARMAX-Nonlinear
autoregressive integrated moving average model with exogenous factors) to model nonstationary
time series whose modeling is limited by such characteristics of accounting data.
