Cooperation And Reciprocity In Anonymous Interactions: Other-Regarding Preferences And Quasi-Magical Thinking, Gregory Klevans Sep 2017

Cooperation And Reciprocity In Anonymous Interactions: Other-Regarding Preferences And Quasi-Magical Thinking, Gregory Klevans

Theses and Dissertations

In economic experiments, players often demonstrate concerns for the relative payoffs between themselves and other subjects, in addition to their own payoffs. In addition, they appear to do their parts to achieve efficient outcomes, particularly when they are ignorant of the opponent's decision. I present a parsimonious model of other-regarding preferences and quasi-magical thinking that explains such behavior, and I apply it to four games: the prisoner's dilemma, the traveler's dilemma, the ultimatum game, and the trust game.

Harriet Jacobs And Toni Morrison: A Tradition Of Narrative Resistance, Allyson L. Molloy Aug 2017

Harriet Jacobs And Toni Morrison: A Tradition Of Narrative Resistance, Allyson L. Molloy

Theses and Dissertations

This article considers historical constructions of power and the narrative as a mode of resistance. Working in different centuries, under extremely disparate circumstances, Harriet Jacobs in Incidents in the Life of a Slave Girl and Toni Morrison in her novel The Bluest Eye, utilize specific narrative strategies to challenge and question institutionalized power which is evidenced through their deliberate employment of narrative strategies not only to challenge the institution of slavery or the hegemonic ideal, but also to question the racial and gender oppression systemic to those institutions of power.
