WTPCIKR: Stata module to estimate Krinsky and Robb Confidence Intervals for Mean and Median Willingness to Pay

P. Wilner Jeanty

Statistical Software Components from Boston College Department of Economics

Abstract: wtpcikr computes mean and/or median willingness to pay (WTP), confidence intervals (CI) based on the Krinsky and Robb (1986) method, achieved significance levels (ASL) for testing the null hypothesis that WTP<=0, and relative efficiency measures (Loomis and Ekstrand, 1998). The command supports both linear and exponential contingent valuation models estimated with or without covariates using the Stata commands probit, logit, and biprobit. It can also be used for user-written maximum likelihood programs as long as the formulas for WTP measures apply. The user bears the responsibility as to whether WTP formulas apply. Users are referred to Haab and McConnell (2002), pp. 52-57 and p. 104 for WTP models and mean/median WTP formulas, and pp. 110-112 for the Krinsky and Robb procedure.
