The treatment of income variable in willingness to pay studies
This paper evaluates income variable specification and functional form issues in contingent-valuation studies using the utility-theoretic approach. Applying data from a study of willingness to pay for irradiated beef, results suggest that functional form does affect the estimates, but variable specification does not introduce statistically significant differences.
