This paper takes sustainability to be a matter of intergenerational welfare equality and examines whether an optimal development path can also be sustainable. It argues that the general “zero-net-aggregate-investment” condition for an optimal development path to be sustainable in the sense...

A tragedy of the commons appears when the users of a common resource have incentives to exploit it more than the socially efficient level. We analyze the situation when the tragedy of the commons is embedded in a network of users and sources. Users play a game of extractions, where they decide...

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....

Technological innovation is a key factor for achieving a better environmental performance of firms and the economy as a whole, to the extent that it helps to increase the material/energy efficiency of production processes and to reduce emission/effluents associated to outputs. Environmental...

This paper investigates the drivers of the environmental innovations (EI) introduced by firms in local production systems (LPS). The role of firm network relationships, agglomeration economies and internationalization strategies is analysed for a sample of 555 firms in the Emilia-Romagna region,...

In the current age of trade and financial openness, local economies in developing countries are becoming increasingly exposed to external investments. The objective of the proposed two-sector model with environmental externalities is to provide an insight into the interaction between external...

Vulnerability to scarcity or to reduction of natural capital depends on defensive substitution possibilities that, in turn, are affected by the availability of other productive factors. However, in several developing countries asset distribution tends to be highly skewed. Taking into ac- count...

We analyse growth dynamics in an economy where the well-being of economic agents depends on three goods: leisure, a free access environmental good and a private good which can be produced by each agent through his own labour input. The private good can be consumed as a substitute for the...

We formulate two kinds of sustainability criteria by using feedback and arbitrary rules for selecting policy variables in non optimizing economies. We show that when policy variables are selected arbitrarily their accounting prices could determine sustainability in addition to the accounting...

Real world observations suggest that social norms of cooperation can be effective in overcoming social dilemmas such as the joint management of a common pool resource – but also that they can be subject to slow erosion and sudden collapse. We show that these patterns of erosion and collapse...
