اولویت های اجتماعی در دوران کودکی و نوجوانی. آزمایش بزرگی برای برآورد انگیزه های اولیه و ثانویه

We elicit social preferences of 883 children and teenagers, aged eight to 17 years, in an experiment. Using an econometric mixture model we estimate a subject’s primary and secondary social preference motivations. The secondary motivation indicates the motivation that becomes relevant when the primary motivation implies indifference between various choices. For girls, particularly older ones, maximin-preferences are the most frequent primary motivation, while for boys efficiency concerns are most relevant. Examining secondary motivations reveals that girls are mostly social-welfare-oriented, with strong equity concerns. Boys are also oriented towards social welfare, but are more concerned with efficiency than with equity.
