Mr. Sidak and Professor Spulber extend here the analysis in Deregulato
ry Takings and Breach of the Regulatory Contract, published last year
in this Review. They respond to comments and criticisms raised not onl
y by Professors Baumol and Merrill, bur also by Judge Williams and Pro
fessor Williamson in their Comments published last year. Sidak and Spu
lber begin by exploring the constitutional limitations on the governme
nt's ability to redefine the public purpose to which a regulated utili
ty has dedicated its private property. Then, the authors examine wheth
er the government has made ''givings'' that implicitly compensate the
regulated firm for its diminution in value owing to the imposition of
policies mandating network unbundling at regulated prices. Sidak and S
pulber refine the limiting principles for the recovery of stranded cos
ts that they articulated in their earlier article and show how those p
rinciples reconcile with the actual treatment of losses from deregulat
ion in disparate industries Next, they expose the economic fallacies b
n the notion of ''forward-looking costs'' as that term has been used b
y the Federal Communications Commission and state public utility commi
ssions to set prices for mandatory network access under the Telecommun
ications Act of 1996. The authors analyze the Supreme Court's 1996 dec
ision in United States v. Winstar Corp. and argue that the reasoning e
mployed by seven Justices in that case comports not only with earlier
decisions of the Court construing the regulatory contract with public
utilities, but also with the contemporary economic analysis of why the
regulatory contract is essential and efficient Sidak and Spulber expl
ain how ''transition bonds'' may solve the stranded cost conundrum in
the telecommunications and electric power industries by permitting the
securitization of stranded costs in a manner that restores investors'
faith in the state's ability to make credible commitments. Finally, t
he authors examine the significance of the Eighth Circuit's 1997 decis
ion in Iowa Utilities Board v. FCC for the debate over deregulatory ta
kings and breach of the regulatory contract.
