“…The survey that used 2.5 RMB and 3.5 RMB as the prices of conventional milk resulted in significantly lower WTP estimates for sustainable milk, implying the importance of controlling the starting value bias in a double-bounded CV method (Herriges & Shogren, 1996;Yang et al, 2013). The coefficients of most of the demographic variables were not significant, which is consistent with the previous research that shows attitudinal and behavioral variables are more important in explaining consumer preferences (Dimech, Caputo, & Canavari, 2011;Gao et al, 2011;Gao, Wong, House, & Spreen, 2014). Education level and whether or not respondents had children are the only two variables that have a significant effect on consumer WTP for sustainable milk.…”
