This paper reveals significant unintended consequences from recent 14-state efforts to reduce greenhouse gas emissions through limits on greenhouse gases per mile from new cars. We show that while such efforts significantly reduce emissions from new cars sold in the adopting states, they cause...

This paper presents an assessment of the relative efficacy of three key instruments – baselines, trade ratios and limits - which are under policy discussion in the design of carbon offset programs. We rank the instruments by their implications for total emissions, economic efficiency, and...
