When majority shareholders want to expropriate minority shareholders, they can try to extract private benefits from the firm. But It is difficult to find a good proxy for private benefits. Should we consider them as a constant fraction of the benefits or some variable amount deducted from the benefits of the firm leaving just enough profitability for the minority shareholders not to forgive the firm? Or should we treat them as a random process correlated with profits, or at last, should we consider something else knowing that this practice may take place when the wedge (difference between ownership and voting rights) is high and the entrenchment of the CEO more or less established?
