Maddalena, Lucia; Fanelli, Viviana - Dipartimento di Scienze Economiche, Matematiche e … - 2008

In this paper we propose a mathematical model with time delay to describe the process of the diffusion for a new … also consider the internal influence from those who already are adopters. The time delay represents the evaluation stage at … which the potential consumers decide whether to adopt the new technology or not. A delay differential equation describes the …

Bayesian learning in mis-specified models

Schinkel, Maarten-Pieter; Tuinstra, Jan; Vermeulen, Dries - Departamento de Economía Aplicada III (Econometría y … - 2000

A central unanswered question in economic theory is that of price formation in disequilibrium. This paper lays down the methodological groundwork for a model that has been suggested as an answer to this question (Arrow, 1959; Fisher, 1983; Hahn, 1989). We consider sellers that monopolistically compete...

PERMANENCE AND GLOBAL STABILITY FOR NONLINEAR DISCRETE MODEL

XIAOXING, CHEN - In: Advances in Complex Systems (ACS) 09 (2006) 01, pp. 31-40

A discrete nonlinear model is studied and sufficient conditions which guarantee the permanence of the model are obtained. Assuming that the coefficients in the model are periodic, the existence of periodic solutions are obtained. Sufficient conditions are obtained to ensure the global stability...

Discrete Dynamical Systems

Galor, Oded - EconWPA - 2005

This manuscript analyzes the fundamental factors that govern the qualitative behavior of discrete dynamical systems. It introduces methods of analysis for stability analysis of discrete dynamical systems. The analysis focuses initially on the derivation of basic propositions about the factors...

A Re-Interpretation of Nash Equilibrium Based on the Notion of Social Institutions

Carmona, Guilherme - EconWPA - 2003

We define social institutions as strategies in some repeated game. With this interpretation in mind, we consider the impact of introducing requirements on strategies which have been viewed as necessary properties for any social institution to endure. The properties we study are finite...
