Course # 44340 Section Number 1 Day(s) M Time(s) 3:00pm-5:50pm Term Spring 2026 Course Instructor Koichiro Ito Syllabus Syllabus 4/10/25 Optimal environmental regulation requires an analysis of the trade between market and regulatory imperfections. Market allocations are inefficient in the presence of imperfections such as externalities, market power, and informational asymmetries. On the other hand, government intervention to mitigate these imperfections is not costless, and can even make market performance worse. This course focuses on recent empirical analysis of the costs and benefits of environmental and energy policies, including an introduction to the relevant econometric methodologies such as randomized controlled trials, regression discontinuity designs, bunching analysis, and structural estimation. Topics will include: energy demand and the energy efficiency gap, fuel economy and appliance efficiency standards, non-linear and real-time electricity pricing, wholesale electricity markets, renewable electricity policies, natural gas markets, retail gasoline markets, and technology innovations. Course Prerequisite In order to register for this course you must be a PPHA PhD student, PPHA-MAR student, PECO PhD student or MAPSS student.
