Economics of Energy Markets


Objectif

This course aims at: 1) developing an understanding of the functioning of energy markets, through the presentation of a variety of relevant concepts and applications; and 2) providing microeconomic and econometric tools of analysis that are useful across many industries beyond energy markets. The course delivers useful background for public and private sector roles in the energy and environmental industries, regulation, research, trading, investment, think tanks, or consultancies.

Plan

This course presents institutional, theoretical and empirical aspects of the economics of energy markets and environmental regulation. Energy consumption is an essential driver of economic activity and the main source of polluting emissions. While energy industries are strongly driven by fundamental economic forces, regulation is an important safeguard to ensure their well-functioning. This course first examines the economic aspects of electricity markets, including its historical and theoretical foundations as well as recent empirical studies. The second part of this course presents the fundamentals of primary energy markets through the theory of exhaustible resources, and the empirical aspects of crude oil and retail gasoline markets. The third part focuses on environmental regulation and the energy transition through the lens of European objectives and policies including emissions markets, energy eciency, and renewable energy deployment.

Topics covered include: natural monopoly, vertical integration, price regulation, regulation of networks, peak-load pricing, market power, antitrust regulation, pay-as-bid vs uniform price multi-unit auctions, supply function equilibria, transmission congestions, the effect of forward contracting, demand-response, capacity markets, Hotelling rule, oil prices, mergers, environmental taxes and cap-and-trade regulation, the effects of environmental regulation, pass-through of emissions pricing, energy efficiency, rebound effect, energy transition, and renewable energy policies.

Enrolled students will have to : 1) make a short presentation (10-15 minutes) about article ; and 2) hand in a short essay (3-5 pages) on one of the themes discussed during the course. In both cases, students will be expected to use the concepts covered, state a research question, present economic intuitions, and deliver their own discussion of the methods and results. Presentations will take place in Session 12. Articles and themes will be assigned a month before the deadline. Small groups will be allowed depending on the number of enrolled students.

The course is organized in 12 sessions of 1h30.
I. The electricity industry

  • A brief history from nationalisation to deregulation in Europe and the U.S.

1. Foundations (Sessions 1-2)

  • Evolving paradigms: natural monopoly and competitive markets.
  • Economic efficiency, peak-load pricing, regulatory issues, investment adequacy, and profitability.
  • The aftermath of deregulation: the California crisis, market power and anti-competitive conducts.

2. Market power in electricity markets: theory (Session 3)

  • Multi-unit auctions (pay-as-bid vs. uniform), supply function equilibria, and transmission networks.

3. Market power in electricity markets: empirical studies (Sessions 4 -5)

  • Measuring market power, the effects of forward contracts and the empirical study of bidding behaviors in multi-unit auctions.

4. Investment and capacity markets (Session 6)

  • Peak-load pricing, the fundamentals of capacity markets, and the study of empirical behavior in capacity markets

5. Demand and retail markets (Session 7)

  • The theory of retail competition, the role of demand-response and the econometrics of price elasticities.

II. Other energy markets
1. Exhaustible resources (Session 8)

  • Dynamic management of an exhaustible resource, the Hotelling rule and the empirical economics of oil prices.

2. Retail gasoline (Session 9)

  • Mergers, collusion, Edgeworth cycles and sticky prices in retail gasoline markets.

III. Energy transition and environmental regulation

  • Brief introduction to the energy transition in Europe.

2. Energy efficiency (Session 11)

  • Investment, rebound effect and efficiency gap.

3. Renewable support policies and fossil fuel subsidies (Session 11)

  • Market integration of renewables, support mechanisms and the costs of fossil fuel subsidies.
