Abstract

Much of the applied work in finance, for instance the literature on capital budgeting, assumes that a firm's management has an accurate estimate of the firm's beta. This estimate is presumably derived by running a regression of the form:where:Ri = rate of return on equity for firm i,Rf = the risk-free rate, andu = a white noise random variable.
