Multidimensional Homophily  

Journal of Economic Behavior and Organization, Vol. 214 (February 2024), pages 486-513. [SSRN Version]

Abstract: Homophily is typically measured using a single dimension to define groups. However, people generally display friendship preferences over multiple dimensions when forming social connections. We develop a simple model that characterizes agents both by a (discrete) "group type" and a (continuous) "personality trait" value. Agents have preferences-for-similarity over both dimensions, but homophily is only measured with respect to group type.  We show that our model belongs to a  more general class of models for which a strongly stable network exits, and identify an algorithm that constructs it. Via simulations, we demonstrate that our model's strongly stable network exhibits three key patterns previously documented in the homophily literature. The model provides new insights and interpretations of these patterns.

Abstract: We propose and develop a dynamic theory of endogenous preference formation in which people adopt worldviews that shape their judgments about their experiences. The framework highlights the role of mindset flexibility, a trait that determines the relative weights the decision maker places on her current and anticipated worldviews when evaluating future outcomes. The theory generates rich behavioral dynamics, thereby illuminating a wide range of applications and providing potential explanations for a variety of observed phenomena.

Preferences for Compensatory and Retributive Justice

Abstract: I experimentally investigate third-party preferences for victim compensation and offender punishment when one party has harmed another. I find that preferences for both compensation and punishment extend beyond pure distributional concerns: they reflect preferences for (what I term) compensatory and retributive justice, respectively. Demands for the two forms of justice are positively correlated across individuals, suggesting that they offer compatible outlooks. Exploring situational factors, I find suggestive evidence that these demands are affected by whether the offender finds out about the victim's compensation and whether the victim learns about the offender's punishment. I then consider a setting where the offender's action only induces probabilistic harm on the victim. I find that whether or not the victim suffers harm affects demands for overall compensation and punishment, but does not affect demands for compensatory or retributive justice.

Motivated Reasoning and Present Focus (with Hunt Allcott, B. Douglas Bernheim, and Tingyan Jia)

In this project, we explore the possibility that individuals use motivated reasoning to justify present-focused behavior. When facing an intertemporal choice involving the present and the future, we convince ourselves that enjoying today (less investment, more leisure, unhealthy food, etc.) is optimal because things will be easier in the future. This generates a specific set of predictions: when choosing today whether to exert effort today or tomorrow, we convince ourselves that we can do less today because the returns to effort will be higher tomorrow relative to today. But when we choose for tomorrow vs. the day after, we do not need to distort our beliefs as there are no immediate actions to be taken today. We develop and run an experiment where we find preliminary evidence of this type of belief distortion.
