Note: The table cross-tabulates the actual change in chilled chicken WTP (one chicken is 1.5 kg). For example, “50 RMB” means someone revealed a 50 RMB WTP (20 RMB premium) for one chicken (1.5 kg). The table reports the number of observations in each category. WTP = 30, 40, 50, 60 RMB correspond to the choice of premium payment card with values of 0, 10, 20, 30 RMB; WTP > 60 RMB correspond to the premium payment > 30 RMB which is out of the choice of all the given payment card so a self-writing value is asked.
