Quantifying and Mitigating Consensus Disparity in Social and Information Networks
Marios Papachristou, Jon Kleinberg
We introduce a computational framework to measure and optimize disparity, which corresponds to the difference in consensus outcomes attributable to distinct social groups, under cl…
Core-periphery Models for Hypergraphs
Marios Papachristou, Jon Kleinberg
We introduce a random hypergraph model for core-periphery structure. By leveraging our model's sufficient statistics, we develop a novel statistical inference algorithm that is abl…
Dynamic Interventions for Networked Contagions
Marios Papachristou, Siddhartha Banerjee, Jon Kleinberg
We study the problem of designing dynamic intervention policies for minimizing networked defaults in financial networks. Formally, we consider a dynamic version of the celebrated E…
Allocating Stimulus Checks in Times of Crisis
Marios Papachristou, Jon Kleinberg
We study the problem of allocating bailouts (stimulus, subsidy allocations) to people participating in a financial network subject to income shocks. We build on the financial clear…
Sublinear Domination and Core-Periphery Networks
Marios Papachristou
In this paper we devise a generative random network model with core-periphery properties whose core nodes act as sublinear dominators, that is, if the network has nodes, the co…
