Company manager altruism and behavioural biases in family firms

Family actors behaviors have not been much studied over the last 20 years, while at the same time, literature about family firms produced increasingly many valuable papers. That is why a relevant Framework for knowing and understanding the behavioral biases of family members is still missing, and this lack concerns also the causes, outcomes and mechanisms of such biases. Particularly and contrary to the prominent literature, the altruism of the manager will be construed as behavioral bias leading to agency costs with an impact on family firm performance. Based on theoretical work, a modeling of these different problems of agency and altruism in the family business will be proposed.(paper in French)
