A Study of Normative Decision Making under COVID-19 Pandemic

The present study indicates a mathematical model regarding the focus theory of normative conduct and estimation methods of parameters related to the degree of decision-makers’ attention by expanding the contingent focus model using web questionnaire data concerning normative decision making under COVID-19 pandemic. We have also shown examples of estimation methods. We made two different assumptions about the parameters and estimated three types of parameters for each assumption; 1) attention degree towards the injunctive norm, 2) relative attention degree on the corresponding level of the factor, 3) a psychological parameter specific to an experimental manipulation. Finally, we discussed the interpretation of parameters and relationships among parameters that were estimated based on two different assumptions.
