Unbundling, Take Two: No Effect on Risk
Robert Rosenberg in his comment on our paper makes a fundamental error regarding financial risk. (Rosenberg, "Unbundling Capital Costs: It Doesn't Add Up," Nov. 1, 1997, p. 46, responding to Maloney, McCormick, and Tyler, "The Wires Charge: Risk and Rates for the Regulated Distributor," Sept. 1, 1997, p. 26.)
Rosenberg claims that as utilities spin off into separate wires and generating businesses, risk will increase in both lines of business.
