From the Miscellany section of Economic Inquiry, Andy Keeler:
Welfare economics must adapt to the growing consensus over the assignment of rights to animals. We extend nonmarket valuation techniques to the study and measurement of the preferences of Chinook salmon regarding their aquatic habitat and the value of their existence. We find that these techniques are as valid for fish as they are for humans. Our applied study indicates that opportunities exist for Pareto-improving trades between salmon and California agricultural and hydropower interests. (JEL Q510)
I feel moved to boast that I provided some feedback, not a formal review, on this paper to the MISC editor.
