Elasticity

Objective. Estimate market impacts of "1+" dialing parity plus eliminating traditional LATA boundary.

Model. Measure shifts in market dominance between major competitors, by assuming price changes and estimating revenue impacts across range of demand elasticities, to reflect both changed rates and market shares. Also consider changes to revenues collected by U S WEST through carrier access charge (CAC).

Scope. Limited to residential toll calls carried by AT&T and U S WEST. Does not examine commercial toll customers.

Data.

When the Federal Communications Commission (FCC) instituted the subscriber line charge (SLC), telephone household penetration rates actually increased, even though local rates rose when the SLC was rolled in.

To what extent should regulation yield to market forces in setting wholesale electric prices? The Federal Energy Regulatory Commission (FERC) posed this question when it sought comments on whether open transmission access would eliminate the need for anything like traditional rate regulation.

In electric power, telecommunications, water, and natural gas, the costs of local distribution make up a significant share of the cost of providing services. For any network or system, the cost of distribution facilities is largely or entirely independent on usage; i.e., such costs are largely invariant to the number of phone calls, kilowatts, British thermal units (BTUs), or gallons that customers use.
