Interest Group Size Dynamics and Policymaking

Interest Group Size Dynamics and Policymaking

We present a dynamic model of endogenous interest group sizes and policymaking. The model integrates ‘top-down’ (policy) and ‘bottom-up’ (individual and social-structural) influences on the development of interest groups. Comparative statics results show that the standard assumption of fixed-sized interest groups can be misleading. Furthermore, dynamic analysis of the model demonstrates that re...

Buying Group Design Considering the Member’s Interest

Enhancing the speed and competition in an exhibition of services and products motivated the companies to provide high-quality products to the customers. One of the effective strategies to reach these goals is to create working groups. These groups can help the companies to improve the quality and exposure of their services along with reducing the costs. This approach is applicable in the health...

Metastable structures and size effects in small group dynamics

In his seminal works on group dynamics Bion defined a specific therapeutic setting allowing psychoanalytic observations on group phenomena. In describing the setting he proposed that the group was where his voice arrived. This physical limit was later made operative by assuming that the natural dimension of a therapeutic group is around 12 people. Bion introduced a theory of the group aspects o...

Temporal Dynamics of Group Size and Sexual Segregation in Ibex

Group size is an important variable describing behavioural ecology of animals. A variety of factors such as habitat characteristics, life history, spatio-temporal resource dynamics, population density, predation risk, competition with kin, and social learning often determine group size in large mammals. We studied temporal dynamics of group size in Siberian Ibex (Capra sibirica) in a protected ...
