This paper presents a theoretical model of an autocrat who controls the media in an attempt to persuade society of his competence. We base our analysis on a Bayesian persuasion framework in which citizens have heterogeneous preferences and beliefs about the autocrat. We characterize the...

In order to verify the effects of machine learning in a market structure, an evolutionary model containing firms that use a genetic algorithm to decide their investment in innovative R&D was developed. These firms share the market, with two other types of firms, those with a fixed rate of...

One of the most important properties of self-organized networks is their scale-free property. Prior research proved empirically and theoretically that scale-free networks emerge under the preferential attachment rule. However, a few empirical studies also show that empirical networks diverge...

This work aims to study the relationship among heterogeneity of demand and innovation taken by firms. Through the contributions of previous works – Valente (2008) and Valente (2012) – it is intended show how the influence of heterogeneous consumers regarding its perceptions, tolerances and...

Various studies have shown the emergence of cooperative behavior in evolutionary models with repeated local interaction among spatially distributed agents. We investigate to what extent these findings generalize to evolutionary models of price competition among spatially distributed firms. We...

The aim of this paper is to present selected models of a Software Development Life Cycle as a set of possible alternatives. The article also includes the characteristics of IT projects which are used as the basis for selection criteria, according to which an appropriate model should be chosen....

The paper deals with an evolutionary model focused on the relation between the behavior of prices and the structure of the population of economic agents. The model allows for identification of the short-term behavior of prices and the dynamics of the population of economic agents in the context...

A simple evolutionary model is used to understand the critical rate of environmental change beyond which a population must decline and go extinct. The model is used to highlight the major determinants of extinction risk in a changing environment, and identify research needs for improved...
