Empirical research typically involves a robustness-efficiency tradeoff. A researcher seeking to estimate a scalar parameter can invoke strong assumptions to motivate a restricted estimator that is precise but may be heavily biased, or they can relax some of these assumptions to motivate a more...

Zackary Dunivin is a candidate in Complex Systems and Sociology at Indiana University. His work draws on various computational tools to study culture and cultural change from the perspectives of dyadic interactions, group dynamics, social movements and formal organizations. This talk presents...

Do search engines produce better results because their algorithm is better, or because they can access more data from past searches? We document that the algorithm of a small search engine can produce non-personalized results that are of similar quality to the dominant firm’s (Google) if it has...

How has mobile internet affected political polarization in the United States? Using Gallup Daily Poll data covering 1,765,114 individuals in 31,499 ZIP codes between 2008 and 2017, I perform a difference-in-differences analysis and an instrumental-variable design to show that, after gaining access...

In this paper we analyze a continuous-time Coase setting with finite horizon, interdependent values, and different discount rates for the buyer and seller. We fully characterize the equilibrium behavior, which permits us to study how the agents’ discount rates (i.e., patience levels) shape the...

Across species and cultures, individuals partition themselves by forming non-overlapping groups. Animals divide into herds, children separate into groups during playtime, politicians create competing political parties, and countries join multilateral defensive treaties. Social network analysis...

We argue that canonical heterogeneous-agent economies are unable to jointly account for the observed concentration of consumption, labor income, wealth, and capital income at the top. We first provide empirical evidence that the distributions of these four variables exhibit asymptotic power-law...

My research advances classical life history theory by integrating methods from evolutionary game theory. This approach sheds light on how interactions among individuals influence the evolution of life history strategies. Specifically, it explores the role of genetic conflicts between family members...
