Dorothea Herreiner is a microeconomist, game theorist, and experimental economist. She is interested in how individuals make choices and how these choices affect and are affected by the circumstances under which they are made. Dorothea has investigated and published on self organization, market institutions and rules. She has applied her knowledge of market structures to art markets (see gallery survey). Dorothea has also focused on the trade-offs between competition and cooperation between players in games, and in particlular, in networks. Another major area of her work and publications deals with fairness and justice criteria, both from a theoretical and experimental perspective. She has also analyzed the role of information, punishment, and externalities in public good and common pool resource experiments. Her most recent work focuses on competition attitudes of males and females and the role of stress in decision making.
