Social network effects on information aggregation
In this thesis, we investigated how sociometric information can be used to improve different methods of aggregating dispersed information. We specifically compared four different approaches of information aggregation: vanilla opinion poll, opinion polls where sociometric data is inferred from the …

Social networks : rational learning and information aggregation
… We address the question of how dispersed information spreads in social networks and whether the information is efficiently aggregated in large societies. The models developed in this thesis allow us to study the learning behavior of rational agents embedded in complex networks. We analyze …

The use of domain knowledge in optimal information aggregation
… relationship between two popular and interesting information aggregation methods: the Condorcet and Borda tallies. I present numerical results showing how the much simpler Borda tally can be used to approximate the outcome of the Condorcet tally with high probability in certain circumstances, a …

Economic experiments on truth-telling, information aggregation, and income inequality
… financial markets to perfectly aggregate private information into asset prices. Along with my co-authors, I conduct an experiment designed to benchmark information aggregation in markets, by randomly assigning subjects to different institutional environments, either a market or a BDM …

Efficient information aggregation strategies for distributed control and signal processing
… by the lack of centralized access to information and time-varying connectivity. Control and optimization algorithms deployed in such networks should be completely distributed, relying only on local observations and information, and robust against unexpected changes in topology such as …

Information Aggregation in Decision Markets under a Modified Hanson Market Maker
… market prices. Utilizing dispersed “not-state” information, we evaluate whether subjects can accurately infer true states and maximize organizational welfare. Our initial baseline results with fully informed subjects demonstrate that while the mechanism can achieve perfect coordination and …

Unknown input and state estimation for linear discrete-time stochastic systems in the presence of constraints
… consists of optimal Bayesian estimation and information aggregation. The optimal estimation provides minimum-variance unbiased (MVU) estimates, and then they are projected onto the constrained space in the information aggregation step. It is shown that the estimation errors and their …
