Information Percolation in Large Markets
We introduce a simple model of the “percolation” of information of common interest through a large market, as agents encounter each other over time and reveal information to each other, some of which they may have received earlier from other agents. We are particularly interested in the evolution of the cross-sectional distribution in the population of the posterior probability assignments of t...
متن کاملInformation percolation in segmented markets
We study equilibria of dynamic over-the-counter markets in which agents are distinguished by their preferences and information. Over time, agents are privately informed by bids and offers. Investors differ with respect to information quality, including initial information precision, and also in terms of market “connectivity,” the expected frequency of their bilateral trading opportunities. We c...
متن کاملInformation Percolation with Equilibrium Search Dynamics∗
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. Individuals choose the effort with which they search for others from whom they can gather additional information. When two agents meet, they share their information. The information gathered is further shared ...
متن کاملSupplementary Information “Percolation in real interdependent networks”
The purpose of this section is twofold: (i) to illustrate in a simpler setting the heuristic approach we used in the main text to study site percolation in interdependent networks; (ii) to provide a connection between the exact results by Bollobás et al. for dense graphs [1], and the heuristic approaches for sparse graphs by Karrer et al. [2], and Hamilton and Pryadko [3]. Consider an undirecte...
متن کاملInvasion Percolation in Presence of Gravity
Simultaneous capillary dominated displacement of the wetting and non-wetting phases are processes of interest in many disciplines including modeling of the penetration of polluting liquids in hydrology or the secondary migration in petroleum reservoir engineering. Percolation models and in particular invasion percolation is well suited to characterize the slow immiscible displaceme...
