Title IV of the Clean Air Act Amendments of 1990 created a market for electric utility emissions of sulfur dioxide (SO2). Recent papers have argued that flaws in the design of the auctions that are part of this market have adversely affected its performance. These papers incorrectly assume that...

Future electricity systems with tight constraints on carbon emissions will rely much more on wind and solar generation, with zero marginal cost, than today. We use capacity expansion modelling of Texas in 2050 to illustrate wholesale price distributions in future energy-only, carbon-constrained...

The "parallel behavior is enough" standard cannot assist the courts in distinguishing horizontal agreements to restrain trade from normal competition. It would very likely impose significant costs on the economy by distorting competitive incentives and encouraging meritless litigation designed...

As we understand it, the D.C. Circuit did not allow the EPA to consider the costs of complying with ozone and PM NAAQS. As we further understand it, this legal ruling can be overturned only by this Court. As economists, we believe that the D.C. Circuit's ruling not allowing the EPA to consider...

Constraints on electric power system carbon emissions will make optimal increased reliance on variable renewable energy (VRE, mainly wind and solar generation), which has near zero marginal operating costs. Using capacity expansion modeling of electric power systems in three US regions in...

The final version of this paper will appear as Chapter 6 in the forthcoming MIT Energy Initiative study, The Future of Storage. Chapters referred to in this paper will be included in that study when it is published. In order to illuminate the role of energy storage in future decarbonized...
