Your response should cover the following:

• What pollutant(s) is(are) studied?
• What do the authors find?
• Why is the paper important? (In some cases, the authors study a relatively specific setting, but we presumably care about the implications more broadly.)
• How do we know that the authors' findings aren't caused by some other factor not included in the analysis? (i.e. How do the authors identify the relationship they find?)
• How does the paper relate to Environmental Economics? How should the findings affect policy? Be specific here (and incorporate paper details)
• What are your thoughts/reactions to the paper?
