In this paper the authors analyze the interaction of two disciplinary mechanisms: competition and reputation. They first study a dynamic model of monopolistic competition with experiencs goods (i.e., quality is observed after goods are purchased). When market power is high enough, reputation...

This paper describes two alternative approaches (modified reverse shooting and forward shooting) for solving the time-path of a representative agent model following an exogenous shock. In particular, reverse shooting is demonstrably better for solving part of the model but must be modified...

This paper shows an endogenous Stackelberg leader-follower relation that stems purely from commitment, not from chronological order of entry. We consider a symmetric duopoly game with a priori demand uncertainty which resolves after a short term. In the beginning, each supplier is allowed to...

Two common properties of macroeconomic models are non-linearities and dynamics characterised by a non-zero number of unstable eigenvalues. Under these circumstances, a common approach is to make analysis more tractable by linearising the model in the neighbourhood of an appropriate steady-state....

The traditional assumption concerning endogenous labor supply in models of economic growth is that utility increases with leisure, independently of the specific time allocation of the representative agent observed at a given moment. In this note, we explore the consequences, over dynamic...

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...
