Information Percolation with Equilibrium Search Dynamics [PDF]

, 2008
We solve for the equilibrium dynamics of information sharing in a large population. Each agent is endowed with signals regarding the likely outcome of a random variable of common concern.

Information-Sharing and Privacy in Social Networks [PDF]

, 2010
We present a new model for reasoning about the way information is shared among friends in a social network, and the resulting ways in which it spreads. Our model formalizes the intuition that revealing personal information in social settings involves a ...

Bounds on the Information Rate of Quantum Secret Sharing Schemes

, 2010
An important metric of the performance of a quantum secret sharing scheme is its information rate. Beyond the fact that the information rate is upper bounded by one, very little is known in terms of bounds on the information rate of quantum secret ...

On Extractable Shared Information [PDF]

Entropy, 2017
We consider the problem of quantifying the information shared by a pair of random variables X 1 , X 2 about another variable S. We propose a new measure of shared information, called extractable shared information, that is left monotonic; that is, the information shared about S is bounded from below by the information shared about f ( S
