Explain how to measure Vf (firm value using the residual income model (RIM) and analyst forecasts), Vbd (firm value based on Burgstahler and Dichev (1997) concept), and Vo (firm value by Hwang and Sohn (2010) incorporating shareholders' real options). What are three important equations for you to assume in measuring Vf using RIM? When does a firm value (i.e., Vf) become the same as its book value of equity (i.e., BV)? What are the differences between these three firm value measures (your answer must include why Vbd is proposed against Vf, and Vo is proposed against Vbd)?
