Summary

This thesis investigates how contextual factors shape social norms and prosocial behavior. Following an introductory chapter, the second chapter examines how the framing of monetary penalties—fees paid upfront versus fines imposed afterward—affects prosocial motivation despite their economic equivalence. The third chapter studies gender differences in punishment, highlighting how social roles and expectations shape discriminatory behavior. The final chapter focuses on leadership in public good provision, contrasting the effects of sequential play with those of role-based leadership. Taken together, the findings show how context, framing, and identity jointly influence cooperation and the enforcement of social norms in experimental settings.
