RESUMO

The Brazilian model of corporate governance is characterized by the ownership and control concentration of most publicly traded companies. In this context, the academic literature points to the existence of a positive and a negative impacts of this shares accumulation by controller (s) on corporate performance, known respectively as incentive effect (or alignment) and entrenchment effect. Several Brazilian and international empirical studies have tested these two hypotheses, however, given the divergence of their results, until now there is no conclusive evidence about the influence of ownership concentration on firm value. Faced with this problem, this thesis had two main goals: search for possible determinants of ownership and control concentration, i.e., test its endogenous character (Part 1); and test whether this concentration influences corporate market value (Part 2). For this purpose, an unbalanced panel for the period of 2001 to 2010 was used, comprising 237 Brazilian non-financial publicly traded companies. In order to mitigate potential sources of endogeneity like missing variables, reverse causality and feedback effect, dynamic models of multiple linear regression were employed, estimated by System Generalized Method of Moments (GMM-Sys). The results of the study\ s first part do not support the hypothesis that the character of ownership and control structure is endogenous. In the second part of the research, the incentive effect was captured by adjusted market value of total shares of the largest shareholder. While the voting right concentration and the separation of ownership and control captured the entrenchment effect.
