WTP to move between options. The WTP figures indicate the cash amount (in Singapore dollars, at 2013 prices S$1≈US$0.80) required to make respondents indifferent between two neighbouring attribute levels, with arrows representing the direction in which the individual would be willing to pay to move. For instance, participants would pay S$15 (as revealed by their choices) to move from a voluntary to a mandatory quarantine policy
