Why Are Allowance Prices so Low ?

چکیده
This paper presents an analysis of the reduction in S02 emissions by electric utilities between 1985 and 1993. We find that emissions have been reduced for reasons largely unrelated to the emission reduction mandate incorporated in Title IV of the 1990 Clean Air Act Amendments. The principal reason appears to be the change in the economics of coal choice that has resulted from the remarkable decline in rail rates for low sulfur western coal delivered to higher sulfur coal-fired plants in the Midwest. We conclude that allowance prices are lower than expected because less sulfur must be removed to meet the Title IV caps on aggregate S02 emissions. Draft: February 5, 1996

Explaining Low Sulfur Dioxide Allowance Prices: The Effect of Expectation Errors and Irreversibility
The low price of allowances has been a frequently noted featured of the implementation of the sulfur dioxide emissions market of the U.S. Acid Rain Program. This paper presents theoretical and numerical analyses that explain the gap between expected and observed allowance prices. The main contributing factors appear to be expectation errors augmented by the presence of irreversible investments.
متن کاملImpacts on CO2 Emission Allowance Prices in China: A Quantile Regression Analysis of the Shanghai Emission Trading Scheme
A pilot regional carbon emission trading scheme (ETS) has been implemented in China for more than two years. An investigation into the impacts of different factors on carbon dioxide (CO2) emission allowance prices provides guidance for price-making in 2017 when the nation-wide ETS of China will be established. This paper adopts a quantile regression approach to estimate the impacts of different...
متن کاملHedonic Prices of Sulfur in Coal under the U.S. SO2 Allowance Market
This study investigates the efficiency of pollution permit markets by conducting an empirical study of the U.S. SO2 market. A hedonic model of coal price is estimated by using the coal price data from 1985 to 1998. The estimation results showed that the sulfur premium was in the same order as the SO2 allowance prices in the EPA auction. In addition, for 1997 and 1998, the SO2 allowance prices w...
متن کاملALLOWANCE TRADING AND ENERGY CONSUMPTION UNDER A PERSONAL CARBON TRADING SCHEME: A DYNAMIC PROGRAMMING APPROACH by Jin Fan School of Management, University of Science and Technology of China
In response to the challenge of climate change, personal carbon trading was put forward as a policy instrument to promote low carbon behavior in the household sector. To evaluate the effectiveness of this scheme, it is important to gain insight into the allowance trading and energy consumption behavior in a long emission commitment period. This paper proposes a dynamic programming model to inve...
متن کاملThe Effects of Coal Contract Constraints on SO2 Trading Program Compliance Decisions
Several studies on Phase I of the Title IV SO2 Trading Program have found that actual compliance costs realized by the electric power industry have far exceeded the least-cost outcome in spite of allowance prices being much lower than expected. Prior work has either conjectured or shown that some of these excess costs could be a result of inefficiencies related to state regulatory constraints, ...
