The evolution of renewable resources is characterized in many cases by different time scales where some state variables such as biomass, may evolve relatively faster than other state variables such as carrying capacity. Ignoring this time scale separation means that a slowly changing variable is...

Optimal portfolio rules are derived under uncertainty aversion by formulating the portfolio choice problem as a robust control problem. The robust portfolio rule indicates that the total holdings of risky assets as a proportion of the investor's wealth could increase as compared to the holdings...

Grandfathering of emission permits creates a rent to incumbent firms since a valuable asset is freely distributed to them. In this paper, we examine the strategic behaviour of polluters that anticipate a change in environmental regulation from a standard-setting to tradable emission permits with...

Empirical investigation of global warming models in economics have started basically with simple calibrations of control models where the whole world was represented by a single agent. Theoretical advances in disaggregated game theoretic models have also motivated the analysis of disaggregated...

Resource-based models of species competition predict that when species compete for a limiting resource in a homogeneous habitat, then the equilibrium outcome is a monoculture with the species characterised by the lowest resource requirement outcompeting all the rest. We derive harvesting rules...

This paper investigates the effect of credibility of environmental policies on environmental innovation and welfare. When the government precommits to an emission tax, the monopolist's abatement effort is lower than if the environmental policy is at the government's discretion. Time consistent...

This paper examines the efficiency enhancing potential of supplementing existing policies of controlling consumption pollution with environmental advertisement. Our definition of environmental advertisement includes both information dissemination and persuasion. While incentive-based regulations...

Recent environmental economics literature regarding global problems, like for example those associated with greenhouse gases, focuses on the emergence of international co-operation and underlying incentives. International co-operation among countries is necessary in the case of global pollution,...

Human economies and ecosystems form a coupled system coevolving in time and space, since human economies use ecosystems services and at the same time affect ecosystems through their production and consumption activities. The study of the interactions between human economies and ecosystems is...

We analyze firms' incentives to coordinate on the introduction of a sustainable product variant when consumers' preferences for sustainability depend on the perceived social norm, which in turn is shaped by average consumption behavior. We show that such preferences could lead to multiple...
