The article discusses and analyzes data from several economic experiments in a household sur-vey with mothers of preschool children. The researchers measured competitiveness by giving the subjects the choice between competing in a tournament or receiving a piece rate for a real effort task. The subjects also participated in lottery choices, which enabled the researchers to assess their risk preferences. The relationship between social preferences and competitiveness in the sample of mothers of preschool children was analyzed. The hypothesis that egalitarian subjects aren't as likely to self-select into competitive environments, which can produce winners and los-ers, was tested. A negative relationship between egalitarian choices and self-selection into com-petition was found.
