The influence of decision-making rules on individual preference for ecological restoration: Evidence from an experimental survey

We conduct an experimental survey to analyze how rules for collective decision-making influence individual preferences concerning nature restoration projects. Our study compares two decision-making rules - a consensus rule and a majority rule - wherein participants decide on a plan concerning nature restoration in the Kushiro Wetland, Japan. Our main finding is that the difference between the individual preferences and collective decision-making is less significant under the consensus rule than the majority rule. Furthermore, there is a larger disparity with regard to the marginal willingness to pay between collective and individual decisions when participants are unsatisfied with the results of collective choice.
