The Problem of Setting Regulated Prices for a Natural Monopoly Price/unit Problem: Competitive-based pricing (P=MC) does not allow adequate cost recovery (< AC). Demand AC Pc MC Output/hr 0 Qc
Setting Regulated Prices for a Natural Monopoly Price/unit Solution 1: PR = AC(Q) Quantity sold = QR Demand PR AC Pc MC Output/hr 0 QR Qc
Problem with setting P = AC • Loss of price signal to consumers • Increases need for (expensive) peak capacity • Increases costs and prices
Setting Regulated Prices for a Natural Monopoly Solution 2: Two-part tariff: Usage charge PR = MC Fixed charge = [AC (Qc)-MC (Qc)] * Qc Price/unit Demand AC AC (QR) FIXED CHARGE 固定支付 PR MC Output/hr QR = Qc 0
Cost-Based Regulated Price for Natural Monopoly Regulated price = Fixed costs (amortization in current year) + Operating costs + return on equity and debt capital
Problems with Cost-Based Regulated Pricing Setting regulated price = fixed costs + operating costs + return on capital invested • Inadequate incentives for efficiency • Need for significant regulatory supervision • Tendency for “gold-plating”
Price Cap: Alternative to Cost-Based Regulated Prices Revenues in base year Rb = costs in base year Revenues in following year = Rb (1 + Ab) Revenues in year t Rt = Rt-1 (1 + At) t = 2,….n At = adjustment in firm’s prices based on inflation and technological change OR average cost increase for sample of comparable firms. If firm’s increase in costs in year t < At →the firm gets to keep thedifference →incentive to be cost efficient However, firm must be subject to quality standards. Otherwise it can cut costs and reduce quality.
