Car use is an increasingly serious problem in many modern cities because of polluting emissions, noise, accidents and congestion. To examine this issue, this paper analyzes the individual choice between taking the car and using alternative transport modes (e.g. walking, cycling, taking the bus...

This work examines the impact that economic growth can have on biodiversity and on the ecological dynamics that would naturally emerge in the absence of human activity. The loss of biodiversity may induce policy-makers to implement defensive actions that prevent single species from extinction....

The paper proposes a new financial mechanism that could be implemented to protect the environment of a tourist region. For this purpose, we investigate the potential consequences of two financial activities, issued by the local government (\emph{G}) of a region\emph{\ R}, which work like...

This paper discusses to what extent the recent trends in energy consumption and production are compatible with the requirements of sustainable development. For this purpose, starting from a simple identity applied to the energy sector, we use the decomposition analysis to derive a few analytical...

The purpose of the present paper is to highlight some features of global dynamics of the two-sector growth model with accumulation of human and physical capital analyzed by Brito, P. and Venditti, A. (2010). In particular, we explore two cases where the Brito-Venditti system admits two balanced...

In this study, we develop an evolutionary game model to analyse how human relations evolve in a context characterised by declining face-to-face interactions and growing online social participation. Our results suggest that online networks may constitute a coping response allowing individuals to...

We analyze growth dynamics in an economy where a private good can be consumed as a substitute for a free access environmental good. In this context we show that environmental deterioration may be an engine of economic growth. To protect themselves against environmental deterioration, economic...

We introduce social capital accumulation into a neoclassical model, showing how it differs from physical and human capital accumulation. We take the view that social capital is crucial to the enjoyment of socially provided goods and that it is mainly accumulated by means of participation to...

We analyze an overlapping generations model where agent’s welfare depends on three goods: leisure, environmental quality and consumption of a private good. We assume that the production process of the private good depletes the natural resource and that the consumption of the private good...

The main objective of the paper is to analyze the effects on economic agents’ behavior deriving from the introduction of financial activities aimed to environmental protection. The environmental protection mechanism we study should permit exchange of financial activities among citizens, firms,...
