  1. aWTP is in cents/km. For a vehicle with a fuel efficiency of 8.5 km/l, the cost per liter can be obtained by multiplying the WTP estimate by 8.5. bWTP for each of the Reduce cluster interactions is calculated at the sample means of the cluster and Reduce variable interaction. cSignificance level of 0.01.
