This paper qualifies Weil [1989]'s according to which dynamic efficiency may fail when agents are infinitely-lived, but "disconnected" from previous ones. It is shown that finite horizons matter in the following sense: if dynamic inefficiency results when the agents have infinite horizons, then...

In this paper we develop a new version of the algortihm proposed in [17] for solving exactly some variants of (un)weighted constrained two-dimensional cutting stock problems. We introduce one-dimensional bounded knapsacks in order to obtain an improved initial lower bound for limitating...

In this article, the authors put forward another viewpoint which shows how a "small noise" (which may be Gaussian) can cause great fluctuations because of the unstable structure of the model skeleton (i.e. its deterministic part) and whihc permits nevertheless to undertake forecast methods in...

We study the estimation of the marginal probability density function of an observable process associated to a weak bernoulli deterministic dynamical system. We use the Parzen-Rosenblatt naive kernel estimator and state conditions under which it is consistent in quadratic mean. We then discuss...

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...

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...

The class of paremetric dynamic latent variable models is becoming more and more popular in economics and finance. Dynamic disequilibrium models, latent factor models, switching regimes models, stochastic volatility models are only few examples of this class of models. Inference in this calss...

This paper extends research in dynamic traffic modeling using METROPOLIS, a dynamic simulation tool. We briefly present an overview of the original departure time choice model introduces by W. Vickrey (1969) for a single O-D pair. Using this framework for our analysis, we explore how the...

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...
