Weitzman’s research has motivated several subsequent papers examining how features of policy design in specific contexts interact with benefit or cost uncertainty to alter the original model’s conclusions.
Examples include Newell and Pizer (2003), Montero (2002b), and Quirion (2004). Consider the following for these papers:

(a) Explain in words the generalization examined relative to Weitzman’s baseline analysis, and how the modeling framework is altered to accommodate the generalization.

(b) Explain how the conclusions regarding the regulator’s appropriate choice of a quantity or price instrument are altered by the generalization.

(c) Summarize any specific examples discussed in the papers in which the generalization is thought to matter for a particular policy or environmental issue.
