Comportamiento supervisor y beneficios privados de la propiedad accionarialun análisis empírico para el caso español

Abstract

The aim of this thesis is, firstly, to analyse if the influence of majority shareholders over company value depends on the existence of conflict of interests between managers and shareholders. Therefore, the higher the expected social benefit is, the higher interest of shareholders to assume the costs derived form monitoring. The second aim of this study is to analyse if the purchase of share blocks in the Spanish capital market is motivated by the value creation derived from monitoring, or by the informative advantage of the acquirers and insider trading, which would highlight the need of an strict application of Governance Codes and vigilance of firms with asymmetric information. The empirical analysis is accomplished using panel data methodology and a logistic regression. Our empirical analysis allow us to conclude that the supervisory role of ownership is more intense in firms where the potential conflict of interest between shareholders and managers is greater, and therefore the value of the firm can be increased through a specific composition of its shareholders. Moreover, the existence of alternative governance mechanisms, that guarantee managerial decisions monitoring, reduce the importance of the investor¿s supervision role. Lastly, we observe a purchase behaviour when an improvement in managerial running is foreseen as a consequence of the supervision, and when there is more asymmetric information and therefore the acquirers can benefit from their position of better informed investors.
