A Polya-type herding happens when the weight of the herd behavior is just the size of the herd, and it is opposed to the weight of the ''rational'' behavior, that is a fixed parameter. In the Ewens limit, when an agent chooses "by himself'', he is a pioneer, given the infinite possibilities of available choices. When he chooses the "herd'', he joins clusters in proportion to their mass.

Abstract
A Polya-type herding happens when the weight of the herd behavior is just the size of the herd, and it is opposed to the weight of the ''rational'' behavior, that is a fixed parameter. In the Ewens limit, when an agent chooses "by himself'', he is a pioneer, given the infinite possibilities of available choices. When he chooses the "herd'', he joins clusters in proportion to their mass.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
