Tóm tắt

This paper provides a brief primer on the concept and addresses some concerns and criticisms for this method. The contents include: consumer demand - this paper assumes that the benefit measured by consumer's surplus is a satisfactory measure of the benefit of policy that brings about lower energy prices and considers key challenges in this approach
  estimating the demand curve
  are two points adequate for estimating the demand curve - a large gain in consumer's surplus is an expected outcome of the large fall in energy costs due to electrification
  whose demand curve is it anyway
  does willingness-to-pay overestimate ability-to-pay
  why is consumer's surplus so large
  aren't the estimates affected by subsidies and taxation
  and why not simply ask consumers about their benefits from electrification.
