The Network Origins of Aggregate Fluctuations
This paper argues that in the presence of intersectoral input-output linkages, microeconomic idiosyncratic shocks may lead to aggregate fluctuations. In particular, it shows that, as the economy… Expand

Distributed Subgradient Methods for Multi-Agent Optimization
TLDR
We study a distributed computation model for optimizing a sum of convex objective functions corresponding to multiple agents. Expand

Systemic Risk and Stability in Financial Networks
This paper argues that the extent of financial contagion exhibits a form of phase transition: as long as the magnitude of negative shocks affecting financial institutions are sufficiently small, a… Expand

Constrained Consensus and Optimization in Multi-Agent Networks
TLDR
We present distributed algorithms that can be used by multiple agents to align their estimates with a particular value over a network with time-varying connectivity. Expand

Opinion Dynamics and Learning in Social Networks
TLDR
We provide an overview of recent research on belief and opinion dynamics in social networks in which individuals are situated on three key questions: (1) whether social learning will lead to consensus, i.e., to agreement among individuals starting with different views. Expand

Spread of (mis)information in social networks
TLDR
We provide a model to investigate the tension between information aggregation and spread of misinformation in large societies (conceptualized as networks of agents communicating with each other). Expand

TLDR
We introduce a new distributed optimization algorithm based on Alternating Direction Method of Multipliers (ADMM), which is a classical method for sequentially decomposing optimization problems with coupled constraints. Expand

Optimal Pricing in Networks with Externalities
TLDR
We study the optimal pricing strategies of a monopolist selling a divisible good (service) to consumers who are embedded in a social network. Expand
