Over the years, scientists in intelligent technologies have adopted several approaches for the automated representation of the real world. An essential part of these attempts is the classification algorithms that give researchers an efficient way of acquiring and ordering data. This is...

Evolving economies can be formally represented in various forms. One of the possibilities we explore is ESO systems, which are basically cellular automata with endogenous rules of change. Another possibility is to consider economic evolution as the result of the nested application of rules of...

The present paper analyzes a network formation problem, mainly based on the framework presented in Bala and Goyal (2000). We depart from their assumptions in two crucial aspects. On one hand, we assume that connecting to an agent pays of not only for the number of connections that the agent can...

In our paper we investigate how network effects influence the dynamics of oligopoly on mature telecommunication markets. The model covers four categories of agents: telecommunication operators, customers joined into housholds and market regulator. The market state aware firms use reinforcement...

This paper sets out first, to quantify the stabilization gains from commitment in terms of household welfare and second, to examine how commitment to an optimal or approximately optimal rule can be sustained as an equilibrium in which reneging hardly ever occurs. We utilize an influential...

Efficient algorithms for diagnosing influential data points are investigated. Techniques examining potentially influential subsets are considered. Given a list of candidate observations, a new row-dropping algorithm (RDA) computes all possible observation-subset regression models. It employs a...

Population aging threatens to severely destabilize the public finances of a majority of European countries. This unfavorable demographic prospect is usually reinforced by a widespread tendency to anticipate retirement. Reversing this tendency has been identified as a crucial factor to improve...

This paper integrates the literature of Mortgage Design with that of Rotating Savings and Credit Associations (ROSCAs) to present a novel way of mortgage financing (with a zero interest rate) using cooperatives. This mode of financing dissipates credit (default) risk better than the normal mode...

A system of agents interacting in a network with a globalization-polaritation transition is studied in the context of a cultural dissemination model. We consider different types of fields interpreted as forms of mass media acting on the system. Both for autonomous and external fields,...
