Les voies d'une refondation du capitalisme: Une responsabilité élargie et une rémunération spécifique de la fonction de contrôle actionnarial

Abstract

The Weighted Average Cost of Capital (WACC) is one of the key concepts of corporate finance. Firstly, we identify the "acceptable" parameters to determine the WACC, taking into account the theoretical framework and the various measures used by practitioners. Secondly, based on numerical simulations, we show that the margin of error ensuing from the way WACC is estimated by finance professionals is important. In conclusion, we propose several alternatives for improving practices in determining the WACC.
