%S TSE Working Paper %A Ingela Alger %T Norms and norm change - driven by social-Kantian preferences %X Norms indicate which behaviors are common and/or considered morally right. This paper analyzes norms and norm change by modeling individuals with social-Kantian preferences, combining material self-interest, Kantian moral concerns, and attitudes towards making a greater or a smaller material sacrifice than others. In an N-person social dilemma, these preferences determine individuals’ personal moral norms and their thresholds for collective behavior (cooperation is conditional on suÿciently many others cooperating). Conditions on preferences and beliefs pro-moting/hampering changes in the behavioral norm (the modal behavior) are iden-tified. Implications for policy interventions aimed at changing norms are discussed in light of the model. %K personal moral norms %K behavioral norms %K beliefs, social-Kantian preferences %K social norms %B TSE Working Paper %V 24-1605 %D 2025 %C Toulouse %I TSE Working Paper %L publications50025
