As recent experience suggests, the most significant economic fluctuations are those that combine real and financial factors. This paper works out a simple model that couples a version of Goodwin׳s (1967) growth cycle model of real fluctuations with insights drawn from a model of financial...

This article explores the Marxian roots of the multiplier in order to clarify its foundations and validity conditions. The authors argue that from Marx’s analysis of the evolution of institutions and technology of exchange crucial insights may be derived. In the light of this analysis Kalecki...

In this paper we examine the role played by environmental externalities in shaping the dynamics of an economy with two sectors (a farming sector and an industrial one), free inter-sectoral labor mobility and heterogeneous agents (workers/farmers and industrial entrepreneurs). We find that, in...

This article describes the years of Goodwin’s ‘third life’ at the University of Siena, stressing in particular his main contributions to economic theory, the evolution in his political and philosophical ideas and his love of art. First, after a brief description of his arrival in Siena and...

This paper extends Goodwin’s growth cycle model by assuming both differential savings propensities and disequilibrium in the goods market. It is shown that both modifications entail an increase in the dimensionality of the dynamical system of the model. By applying the existence part of the...

This paper proposes a simple prototype model that describes the complex dynamics of a sophisticated monetary economy. The interaction between the current and intertemporal financial constraints of economic units brings about irregular fluctuations at the micro and macro levels. By means of...

From a given directed weighted network of knowledge links between technology fields, the paper develops a multisector dynamic model of incremental innovation and R&D activity in these fields. The model is focused on the equilibrium share distribution of these variables, which is proved to be...
