Following the line of argument of the institutional approach, an analysis of the role of financial information prepared for external purposes and its role in a space dominated by cultural hybridity is proposed. By highlighting the cultural and institutional aspects affecting the management styles after the incursion of the accounting information model based on the International Financial Reporting Standards (IFRS), the way the process has been assumed in Colombia is made problematic. In this regard, it is characterized, at first, the role of information in an institutional setting and, in a second step, the type of agency produced in a space regulated by institutions. To this end, institutional economics, on the one hand, and the anthropological approach on cultural hybridity by Nestor Garcia Canclini, alongside a Weberian comprehensive sociology, on the other, are assumed. The methodology that will be used is a descriptive / explanatory type and it is focused on understanding the formal rationality of the external financial information in contexts where cultural hybridity exists. In essence, it is stated that a clash of mentalities occurs when formal rationality and management styles based on tradition coexist.
