Since 2007, coal-fired electricity generation in the US has declined by a stunning 25%. At the same time, natural gas-fired generation and wind generation have dramatically increased due to technological advances and policy interventions. We examine the joint impact of natural gas prices and...

Strikingly, Ogawa and Wildasin (2009) find that in a model with heterogenous jurisdictions, interjurisdictional capital flows, and interjurisdictional environmental damage spillovers, decentralized planning outcomes are equivalent to that under a single centralized planner. Taken to its extreme...

Understanding how drivers respond to fuel price changes has important implications for highway congestion, accidents, carbon policy, local air pollution and taxation. We examine the underexplored relationship between fuel prices and carpooling. Using a simple theoretical model we show that...

Wind power has the potential to reduce emissions associated with conventional electricity generation. Using detailed, systemic hourly data of wind generation and emissions from plants in ERCOT (Texas), CAISO (California), and MISO (Upper Midwest), we estimate the SO₂, NOₓ and CO₂ emissions...

We consider a North-South trade model with cross-border environmental damage where the North imports the relatively dirty good. The North sets domestic production taxes according to each industry’s contribution to environmental degradation (Pigouvian taxes), but this exacerbates cross-border...

We consider the legal and economic context for border adjustments that might be used to augment subglobal carbon abatement. Following Markusen (1975) we establish optimal border policy in the presence of cross-border environmental damages. The optimal border policy includes a strategic component...

On July 1st, 2008, California enacted a ban on hand-held cell phone use while driving. Using California Highway Patrol panel accident data for California freeways from January 1st, 2008 to December 31st, 2008, we examine whether this policy reduced the number of accidents on California highways....

It is generally accepted that decentralized policy choice in the presence of interjurisdictional spillovers is inefficient. Strikingly, Ogawa and Wildasin (2009) find that in a model with heterogenous jurisdictions, interjurisdictional capital flows, and interjurisdictional environmental damage...
