As a companion to A Primer on Nonmarket Valuation edited by P.A. Champ, K.J. Boyle, and T.C. Brown (Kluwer Academic Publishers) we developed this website to provide datasets corresponding to each of the nonmarket valuation techniques described in the Primer. We've also included the surveys used to collect the data, the codebooks (explanation of how the data are coded), and links to the publications based on the data.
