This essay is an initial exploration of the dimensions of the equity/sustainability linkage from the perspective of public goods analysis. Sustainability requires an abundance of public goods. Where these commons lack governance, sustainability is at risk. Equity is a critical component of...

We reformulate the Verhulst-Lotka-Volterra model of natural resource extraction under the alternative assumptions of Cournot behaviour and perfect competition, to revisit the tragedy of commons vs the possibility of sustainable harvesting. We stress the different impact of demand elasticity on...

Over the past few years, there has been a significant increase in the number of initiatives seeking to mobilize investor voice towards positive social impact. In this paper, I provide a framework outlining the role of investors as stewards of the commons. While companies are increasingly...

When confronted with market weaknesses and failures determining sustainability problems for environmental common-pool resources, economic analysis has proposed government intervention as the only alternative available. Elinor Ostrom showed that this dichotomy between market and government is not...

We investigate renewable resources when the harvesting agents face self-control problems. Individuals are conceptualized as dual selves. The rational long-run self plans for the infinite future while the affective short-run self desires to maximize instantaneous profits. Depending on the degree...

We prove that a natural monopoly can set subsidy free pricing and sustainable pricing schedules in general economic environment. The setting is a multiproduct and multiple agent contestable market where demands are elastic and where rivals can enter the sub-markets composed by a set of the...

We provide some existence results of stable pricings for natural monopoly as defined in the theory of contestable markets. The main addings are based on the assumption of separated markets and the possibilities of entries. We borrow tools from cooperative game theory. Following the work of...

We prove the existence of subsidy free and sustainable pricing schedule in multiproduct contestable markets. We allow firms to discriminate the local markets that are composed by a set of the products line and a set of agents. Results are obtained under an assumption of fair sharing cost and...
