This is motivated by the need to include issues of risk, uncertainty, irreversibility, learning and catastrophe in analyses of climate change, particularly integrated assessment models used to investigate limate change policy.

The purpose of this article is to examine the preservation of biodiversity as an economic problem. Using a very simple prototype model, we discuss how to include diversity in the objective function and how to develop a simple cost-benefit ranking criterion for ordering priorities. Then we...

"Green NNP" is a national accounting concept that substracts off from GNP not just depreciation of capital, but also depletion of environmental assets evaluated at competitive of efficiency prices. Recent literature shows that, for a time-autonomous technology, Green NNP has regorous welfare...

The study of natural catastrophe models plays an important role in the prevention and mitigation of disasters. After the occurrence of a natural disaster, the reconstruction can be financed with catastrophe bonds (CAT bonds) or reinsurance. This paper examines the calibration of a real...

A species' risk of extinction is estimated by the deterioration state of the population. A wild and non extinct species could be evaluated and ranked as follows: Critically Endangered, Endangered, Vulnerable, Near Threatened, Of Minor Concern. This ranking has been applied in Colombia for some...

The Mexican Ethanol Project has the potential of power up rural economy, improve the environment quality, and substitute the non-renewable fossil energy resources. But the risk of not achieving these is latent: the market distorts that it could unleash can change the expected outcomes. Public...

In this paper, a manager borrows external funds in order to invest in production and also in prevention. The latter action must reduce the environmental risk driven by the activity of the firm. Prevention is observable neither by outside lenders nor by institutions such as environmental agencies...

Recent research in natural sciences shows that boreal forests' dynamics are much more complex than what many models traditionally used in forestry economics reflect. This essay analyses some challenges of accounting for such complexity. When forest owners continuously harvest several species,...

In this paper we analyse interregional freight transport movements in Europe with a view on new spatial patterns based on transport economic scenarios for environmental sustainability. Two different approaches are compared. viz. the logit model and the neural network model. The paper will...
