Replication package for "When do contingent valuation and discrete choice experiments converge? Evidence from a meta-analysis of environmental valuation studies"

Replication package for the article “When do contingent valuation and discrete choice experiments converge? Evidence from a meta-analysis of environmental valuation studies”. The package contains the dataset of 60 within-study comparisons between contingent valuation and discrete choice experiment estimates of willingness to pay, drawn from 40 environmental valuation studies that satisfy an explicit four-condition comparability rule; the verification log that records every extracted value against its primary source; the design coding sheet with the verbatim evidence behind every classification; a codebook of 70 entries; and two independent implementations of the analysis, in Stata and in R, which are cross-checked coefficient by coefficient. No primary survey data were collected: every value is extracted from a published study.
