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 proportional taxation is, as common wisdom believes, always stabilizing, in the case of non-linear progressive taxation, an increase...

A common belief of mainstream economics as well as underpinning government policy is that the more flexible real wage is, the lower is unemployment. In this paper we study the dynamics of a standard neoclassical labour market under the simplest Walrasian adjustment rule. We show that when...

The issue of the onset of Malthusian cycles is investigated by means of a demo-economic model incorporating the age structure of the population. It is shown that the delayed recruitment into the labour force is a major source of demo-economic instability, potentially leading to sustained...

A common belief in economic growth theory is that the instability of the balanced growth path of models based on a non-neoclassical production theory, such as the Harrod-Domar or Goodwin-type models, may be removed by introducing neoclassical technology and substitutability between factors. This...

We exploit a multistate generalisation of a classical, one-sex, stable population model to evaluate structural and long-term effects of changes in the attainment of adulthood. The demographic framework that inspired this paper is provided by Italy, where a strong delay in the transition to...

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...
