September 2009Who Counts in Evaluating the Effects of Air Pollution Policies on Households? Non-Market Valuation in the Presence of Dependencies
with Mary F. Evans, V. Kerry Smith: w15366
Individuals who are likely to realize the largest benefits from improvements in air quality often depend on other members of their households to make time or monetary contributions to their care. The presence of these dependency relationships among household members poses challenges for benefit estimation since it is unlikely that the conditions necessary for recovering the underlying individual preferences from household choices are satisfied in this setting. We propose a conceptual framework that highlights the role of these dependencies in the choice models used to estimate the willingness to pay for environmental quality improvements. We design a complementary stated preference survey that describes hypothetical dependency relationships for household members of different ages to tes...
March 2008Can Weak Substitution be Rehabilitated?
with V. Kerry Smith, Mary F. Evans, H. Spencer Banzhaf: w13903
This paper develops a graphical analysis and an analytical model that demonstrate how weak substitution can be used for non-market valuation. Both weak complementarity and weak substitution can be evaluated as restrictions that allow quantity or quality changes in non-market goods to be described as price changes that yield equivalent changes in individual well being. They are Hicksian equivalents in that the price changes yield the same utility changes as would the quantity or quality changes. After discussion of several potential applications of weak substitution, the paper develops the parallel between the restriction and recent strategies from modeling differentiated goods.
