In general, it is acknowledged that the managers are better informed than the shareholders. Also, controller shareholders seem to be better informed than the minority shareholders. How to measure the information asymmetry? Can we connect information asymmetry with the dividend policy of companies?
For instance, some studies prove that "Firms that pay consistently high dividends have lower insider returns than do firms that pay consistently low dividends" (e.g., Kenneth Khang and Tao-Hsien Dolly King, Financial Management, Vol. 35, No. 4, 2006).
Thank you in advance!
