Detection of non-self-correcting nature of information cascade
Shintaro Mori, Masafumi Hino, Masato Hisakado +1
We propose a method of detecting non-self-correcting information cascades in experiments in which subjects choose an option sequentially by observing the choices of previous subjec…
Detection of phase transition in generalized Pólya urn in information cascade experiment
Masafumi Hino, Yosuke Irie, Masato Hisakado +2
We propose a method of detecting a phase transition in a generalized Pólya urn in an information cascade experiment. The method is based on the asymptotic behavior of the correlati…
Component Ratios of Independent and Herding Betters in a Racetrack Betting Market
Shintaro Mori, Masato Hisakado
We study the time series data of the racetrack betting market in the Japan Racing Association (JRA). As the number of votes t increases, the win bet fraction x(t) converges to the…
Phase transition and information cascade in a voting model
Masato Hisakado, Shintaro Mori
We introduce a voting model that is similar to a Keynesian beauty contest and analyze it from a mathematical point of view. There are two types of voters-copycat and independent-an…
Infectious Default Model with Recovery and Continuous Limit
Ayaka Sakata, Masato Hisakado, Shintaro Mori
We introduce an infectious default and recovery model for N obligors. Obligors are assumed to be exchangeable and their states are described by N Bernoulli random variables S_{i} (…
Correlated Binomial Models and Correlation Structures
M. Hisakado, K. Kitsukawa, S. Mori
We discuss a general method to construct correlated binomial distributions by imposing several consistent relations on the joint probability function. We obtain self-consistency re…
