Annual global CO2 emission forecasts at 2100 span 10 to 40 billion tonnes. Modeling work over the past decade has not narrowed this range nor provided much guidance about probabilities. We examine the time-series properties of historical per capita CO2 emissions and conclude that per capita...

A problem of sequential decision making under uncertainty involving the testing and regulating of a potentially hazardous substance is analyzed using the Variable Sample Probability Ratio Test.

Evidence suggests that a surprisingly large fraction of firms comply with pollution emission standards even though expected penalities for noncompliance are low. We offer an explanation of this puzzle by extending the standard model of enforcement to include a self-seporting requirement and...
