CSH Lecture Series on Network Inequality – with Jordan Kemp

"Cooperation and Inequality in Stochastic Models of Growth" Group formation and collective action are fundamental to cooperative agents seeking to maximize resource growth. Researchers have extensively explored social interaction structures via game theory and homophilic linkages, such as kin selection and scalar stress, to understand emergent cooperation in complex systems. However, we still lack a general theory capable of predicting how agents benefit from heterogeneous preferences, joint information, or skill complementarities in statistical environments. In this talk, we derive general statistical dynamics for the origin of growth and cooperation based on the management of resources and pooled information. Specifically, we show how groups that optimally combine complementary agent knowledge in statistical environments maximize their growth rate. We show that these advantages are quantified by the information synergy embedded in the conditional probability of environmental states given agents' signals, such that groups with a greater diversity of signals maximize their collective information. It follows that, when constraints are placed on group formation, agents must intelligently select with whom they cooperate to maximize the synergy available to their own signal. We then show how heterogeneity across groups drives resource inequality, which can be mitigated across similar groups through learning in shared environments. These results show how the general properties of information underlie optimal collective formation and drive the emergence of inequality in social systems.

He researches novel theories of social and biological organization by studying agent decision-making in noisy environments. By combining techniques from statistical physics, information theory, and cognitive psychology, he derives theories for agent learning and growth, and then studies how these behaviors aggregate at the population level to drive inequality, coordination, and competition. This exciting research blends ideas from physics, machine learning, and behavioral psychology, and hopes to answer open questions from across the social sciences. It is conducted through the Mansueto Institute of Urban Innovation and the Department of Ecology and Evolution under the advice of Luís Bettencourt. Jordan comes from a small town at the base of the Appalachian Mountains in rural Pennsylvania, and did his undergraduate degree in physics at Tufts University. He also loves to enjoy the outdoors, follow politics, appreciate music and film, as well as coach and play basketball.
