| Abstract: | In this study, it is shown that the value relevance of the financial information, measured by the coefficient of determination (R2), has improved as consequence of the changes in the financial reporting standards. It is applied the Ohlson model (1995) with accounting variables (earning per share and book value) and the stock market price of Mexican stock market companies, during the period from 1992 to 2010. The econometric results are obtained applying an Ordinary Least Squared Regression Analysis and a Panel Data Analysis. The sample is divided in two periods, before and after the foundation of CINIF, and the Chow test is applied to confirm the existence of a structural change. The book value variable is consistently significant in both periods. The Ohlson model is also applied to sub-samples which distinguish the firm for its size, for belonging to the Food and beverages industry and for its classification as Tangible and Intangible firms. |
