.... this methodology is vulnerable to errors in the specification of the functional form or error term(s) The mathematical programming approach avoids this type of specification error by imposing somewhat less structure on the optimization problem, i.e. neither functional form nor error term 4 Cummins and Zi (1998) apply a variety of econometric and non parametric techniques to estimate 5 cost efficiency for a sample of U.S. life insurers. They find that econometric efficiency estimates are robust to the choice of distributional assumptions from the error term. The rank correlations among efficiency ....
....functional form consists of a quadratic component for outputs, linked through interaction terms with a log quadratic component for input prices. The resulting functional form can be estimated linearly, log linearly or using a Box Cox transformation. This functional form has been used by Berger, Cummins, and Weiss (1998) to analyze economies of scope in the insurance industry, considering firms that specialize in either life or property liability insurance along with those that write both types of insurance. 11 See Mitchell and Onvural (1992) for an application to banking and Berger, Cummins, and Weiss 6 ....
