Is there a causal relationship between shocks to renewable natural resources, such as agricultural and forest lands, and the intensity of conflict? In this paper, we conduct a rigorous econometric analysis of a civil conflict that the Indian Prime Minister has called the single biggest internal...

Dynamic optimization problems cover a large class of problems in theoretical and applied economics. A simple iterative algorithm with fast convergence is proposed. It is demonstrated that the algorithm in a few steps produce excellent analytic (closed form) approximations including error bounds...

In this paper we consider an endogenous growth model in which, among other inputs, we consider a renewable resource and secondary materials. Using this analytical framework we explain the effects of waste recycling on the growth rate of the economy, that we take into account. The effects of...

This paper examines a simple North-South growth model where negative externalities may contribute to reinforce economic growth. Agents' welfare depends on three goods in the model: leisure, a common access renewable natural resource (one in each hemisphere) and a non-storable consumption good....

Optimal harvesting of prey in a predator–prey ecosystem is studied under the condition that the existence of the predator has value. Predators (birds) and humans (fishers) compete for prey (shellfish). The behavior of the system is studied and conditions for optimal control are deduced....

We analyze how the threat of a potential future regime shift affects optimal management. We use a simple general growth model to analyze four cases that involve combinations of stock collapse versus changes in system dynamics, and exogenous versus endogenous probabilities of regime shift. Prior...

Optimal management of biodiversity at the national level, even if achievable, is not necessarily consistent with a global optimum. While the existence of trading relationships allows for the possibility of the use of trade interventions as a means of imposing unilateral solutions, the presence...

We incorporate a renewable resource into an overlapping generations model without capital and with quasi-linear preferences. Besides being an input for production the resource serves as a store of value. We characterise the dynamics, efficiency and stability of the steady state equilibria. The...

After the 2000 Water-War, access to water in Bolivia has become a major social demand and thus a prime and contentious political issue. The event has revealed an overwhelming opposition to neo-liberal approaches to water management and has allowed the articulation of a new discourse that sees...

We analyze how the threat of a potential future regime shift affects optimal management. We use a simple general growth model to analyze four cases that involve combinations of stock collapse versus changes in system dynamics, and exogenous versus endogenous probabilities of regime shift. Prior...
