Allegations of market power in wholesale electricity sales are typically tested using price-cost margins. Such tests are inherently suspect in markets-such as electricity-that are subject to capacity constraints. In such markets, prices can vary with demand while quantity, and thus cost measure,...

Restructuring the electricity market may secure efficiencies by moving away from cost-of-service regulation, with typically (but not necessarily) time-invariant prices, and allowing prices to reflect how costs change. Charging "real time" prices requires that electricity use be measured...

This paper explores ways in which economic analysis can help resolve the stranded cost controversy that has arisen in debates over electricity market deregulation. "Stranded costs" are costs electric utilities will not recover as power markets move from protected monopolies to an open,...

Using rockets to launch communications satellites and other spacecraft poses risks to the uninvolved public, including persons and property under the flight path of the launch vehicle. The federal government plays a pivotal technical role during the actual launch by carrying out certain...

Under conventional models, subsidizing energy efficiency requires electricity to be priced below marginal cost. Its benefits increase when electricity prices increase to finance the subsidy. With high prices, subsidies are counterproductive unless consumers fail to make efficiency investments...

The cliché in the electricity sector, the "cheapest power plant is the one we don’t build," seems to neglect the benefits of the energy that plant would generate. Those overall benefits could be countered by benefits to consumers if "not building that plant" was the result of monopsony. A...

Among the many complex issues of technology, governance, and market design affecting the electricity sector, climate policy has become dominant. From the perspective of a nonspecialist looking at this changing dominance, a quiz illuminates some of the peculiar uses of language one can find in...
