Calculation of vegetation indices, especially Normalized Difference Vegetation Index (NDVI), has become one of the most successful, popular and traditional attempts in biogeographical research methods, because NDVI has certain advantages over other vegetation indices or band combinations. The...

I propose and develop a framework for the financial economic analysis of investing with altruistic preferences. A key part of the framework is the precise definition of different forms of impact and, in particular, investor impact. This has several practical implications including that investor...

Trillions of dollars are now invested with both implicit and explicit altruistic goals. To address the unique concerns arising from these goals, I develop a tractable general equilibrium model that combines investment, production and altruistic considerations. I use this model to examine the...

With the United States’ reentry to the Paris Agreement, there is now consensus among the world's largest carbon emitters that emissions must be reduced. But there is still a radical lack of consensus on what regulations should be chosen to reduce carbon. Worse, there is also a radical...

Man’s history and developmental endeavour have been advancing alongside a trail of ecological ramifications and climate change. Since prehistoric times, scientists have not recorded an accelerated shift in ecology during any other epoch beside that of modern man on the planet. The paper seeks...

Nature conservation scientists and practitioners have voiced the concern that a conservation discourse based on economic arguments and monetary valuation may undermine conservation efforts by eroding ("crowding out") the influence of other arguments for nature conservation. This paper presents...

Understanding what influences the value of nature is crucial for informing environmental policy. From a sustainability perspective, economic valuation should not only seek to determine willingness to pay for environmental goods to devise an efficient allocation of scarce resources, but should...

The paper develops an axiomatic framework for rational decision making. The von Neumann-Morgenstern axioms give rise to a richer risk attitude than that captured in the standard discounted expected utility model. I derive three models that permit a more comprehensive risk evaluation. These...
