Theoretical models of growth and trade suggest that patterns of international specialisation are inherently dynamic and evolve endogenously over time. Initial comparative advantaged are either reinforced or gradually unwound with the passage of time. This paper puts forward an empirical...

These lecture notes have been prepared as a preliminary material for the first year graduate students attending the ocre macro course in the Finnish Postgraduate Programme in Economics. The notes should make it easier for students to acquaint themselves with the overlapping generations models in...

We present a general framework for understanding the transition from local regular to global irregular (chaotic) bahaviour of nonlinear dynamical models in discrete time. The fundamental mechanism is the unfolding of quadratic tangencies between the stable and the unstable manifolds of periodic...

We examine the effect if two specific noises (either known or small ones) on a dynamical system. We obtain consistent estimates with their rates of convergence for the invariant density in that context.

Under the conditions of efficiency, a simple economic system is thought to have a unique market attractor, and thus a unique stable fixed point. By contrast, in more complex socioeconomic systems, multiple attractor dynamics predominate. This paper proposes a dynamical representation of suhc...

This paper presents new models and methodologies for the assessment of innovative urban transport systems and policies options. The dynamic traffic model METROPOLIS (used here in the framework of the EC project AIUTO) estimates the impact of a set of transport demand management measures on the...

We present a general framework for understanding the transition from local regular to global irregular (chaotic) behavior of nonlinear dynamical models in discrete time. The fundamental mechanism is the unfolding of quadratic tangencies between the stable and the unstable manifolds of periodic...

This paper develops a formal framework based on multivariate spectral techniques for assessing the performance of multivariate dynamic models whose solution is approximated through simulation. The approach is especially suitable for models that focus on a particular frequency range , such as...

In this work we propose a new model for the analysis of telecommunications (Tlc) networks production. This represents an extension of the fund-flow model by Georgescou-Roegen originally applied to the manufacture and agriculture sectors. The adopted framework enables us to describe the...
