We discuss various technical problems that have arisen in attempting to
implement the Telecommunications Act of 1996, the purpose of which was
to ensure fair competition in the local telecommunications market. We
treat the interpretation of the "parity'' requirement, testing the
parity hypothesis, the effect of correlation, disaggregation and
reaggregation, "balancing,'' benchmarks, payment schedules and some
computational problems. Also we discuss the difficulty of working in an
adversarial (rather than scientific) environment.
