An information (or informational) cascade occurs when people observe the actions of others and then make the same choice that the others have made, independently of their own private information signals. Because it is usually sensible to do what other people are doing, the phenomenon is assumed to be the result of rational choice. Nevertheless, information cascades can sometimes lead to arbitrary or even erroneous decisions. The concept of information cascades is based on observational learning theory and was formally introduced in a 1992 article by Sushil Bikhchandani, David Hirshleifer, and Ivo Welch.[1] A less technical article was released by the authors in 1998.[2][3][4][5]
