This paper offers a unified perspective of the analytical detection of Hopf bifurcation, which is a crucial tool in dynamic economic modelling. We clarify the relations between stability theorems and the notions of Simple and General Hopf Bifurcations. A Lienard-Chipart-type theorem for...

Much of the debate on the role played by the age distribution of the population in shaping the growth regimes of the neoclassical growth model of Solow has focused on the notion of capital dilution and the possibility that "optimal" population growth regimes (OPGR) exist. Conversely less has...

It is shown here that the Solow (1956) neo-classical growth paradigm not only explains the "first" stylised fact of economic growth, namely the existence of a globally stable state of balanced growth, but, once endowed with a demographically founded formulation of the labour supply, is also...

The relationship between wage inflation and unemployment has been extensively investigated since the early work of Phillips (1958) and Lipsey (1960), and is still a matter of debate. In this paper we study the dynamics of a standard neoclassical labour market under Walrasian adjustment rules. We...

The paper investigates the role of progressive income taxation in the frame of the basic multiplier-accelerator model in continuous time. It is shown that, while the proportional taxation is, as common wisdom believes, always stabilizing, in the case of non-linear progressive taxation, an...

In this paper the dynamical effects of public environmental policies are investigated in a Cournot duopoly with heterogeneous expectations in a context of limited rationality. It is shown that the introduction of upper limits to emissions always tends to destabilise and generate a chaotic market...

This paper discusses the dynamics of a standard (double Cobb-Douglas) labour market under the circumstance of changes in returns to labour. Despite the simplicity as well as the vast diffusion of this model, such an issue has so far escaped closer scrutiny by economic dynamics literature. This...

Motivated by the increasing literature on endogenous preferences as well as on endogenous fertility, this paper investigates the implications of the interaction of the endogenous determination of the number of children with habit and aspiration formation in an OLG model. In contrast with the...

This paper analyses the effects of a downstream merger in a differentiated duopoly under price competition and plant-specific unions. We show, in contrast with the preceding literature, that the standard welfare results may be reversed: a downstream merger may increase consumer surplus and...

Abstract Motivated by the widespread presence both of decentralised unions and cross-participation at ownership level (for instance in Japan and US), this paper aims at investigating whether the conventional wisdom that a reduction in the degree of product differentiation (which increases...
