  • (1)*p<0.10, **p<0.05; (2) SD is the SD ofthe random coefficient, only SD for statistically significant attributes shown; (3) SE in parenthesis; (4) WTA estimates are in rupees (US$1=INR70), WTA estimated only for statisticallysignificant attributes; (5) to be concise, interaction results are only shownfor statistically significant interaction.

  • *WTA estimates are per visit.

  • AIC, Akaike information criterion; INR, Indian rupee; WTA, willing to accept.
