Indeed, these patterns do not make immediate sense in terms of traditional macro- or microeconomic models. Still, they may be rational for an individual or a group of individuals. Learning by observing other individuals' past actions and decisions may be of help to explain some otherwise puzzling phenomena about human behaviour. Apprehending individuals' behaviour is not straightforward. It is not only profit or utility maximising that drives individuals' minds. Sometimes, individuals just act because others act. An Informational Cascade is a situation in which every subsequent individual, based on the observation of others, makes the same choice or decision independent of his private information. Informational Cascades are present in our everyday life and in fields such as Economics, Politics, Scientific Theory, Finance or Zoology. The fact that this phenomenon does appear in innumerable situations is my motivation to closer examine Informational Cascades. Economics and above all economic behaviour is more than Statistics or Mathemati
