Despite favourable ecological and economic results, many developing countries have not yet adopted an integrated pesticide management (IPM). Given rising marginal costs and diminishing marginal benefits from IPM technology transfer, an optimal control framework is used to identify optimal rates...

Few textbooks in mathematical economics cover optimal timing problems. Those which cover them do it scantly or in a rather clumsy way, making it hard for students to understand and apply the concept of optimal time in new contexts. Discussing the plentiful illustrations of optimal timing...

This note gives a brief, non-rigorous sketch of basic optimal control theory, which is a useful tool in several simple economic problems,such as those in resource and environmental economics. While the mathematical analysis in the note is self-contained, there is not much explanation and...

Advertising is tied to global warming through an endogenous growth model. The model allows for the possibility that the environment can become a source rather than a sink for greenhouse gases. Optimal control analysis of the model shows that a feasible steady state is possible for which the...

We propose a dynamic graph-theoretic model for ecosystem management as a control over networked system composed of target nodes and unmarked nodes. The network is represented by a complete graph, in which all vertices are connected by a unique edge. Target nodes are attracted by the objective...

This paper attempts to model the positive role of cultivation of Genetically Modified (GM) crop with its soil-anchoring root-characteristic and use of conservation-tillage technology, in saving organic matter contents in the topsoil and reducing soil erosion. In a dynamic optimization framework...

The purpose of this study is to evaluate ethanol cost- effectiveness with regards to carbon dioxide emissions. Actually, bio-fuel production is only viable thanks to the tax credit policy resulting in economic ‘deadweight’ loss. The environmental performance is assessed under the Life Cycle...

Disaster managers allocate resources to accomplish a set of objectives in a highly uncertain environment. The allocation decisions made throughout the course of a disaster inevitably impact final outcomes such as the damage and cost of a disaster. We develop a unique stochastic dynamic model of...

We consider optimal behavior in a class of spatial-dynamic economic problems related to a negative externality with stock effects, via the development of a dynamic, non-cooperative game. The feedback Nash equilibrium response functions are parameterized based on an invasive weed faced by western...
