We couple a spatially homogeneous energy balance climate model with an economic growth model which incorporates two potential policies against climate change: mitigation, which is the traditional policy, and geoengineering. We analyze the optimal policy mix of geoengineering and mitigation in...

We explain the spatial concentration of economic activity when the cost of environmental policy – which is increasing in the concentration of pollution – acts as a centrifugal force, while positive knowledge spillovers and a site with natural cost advantage act as centripetal forces. We...

We present a selective review of migration and its connection with the economy, focusing on issues leading towards a modelling perspective.We introduce a class of models based on difference equations on directed graphs that may provide a quantitative and qualitative description of human...

The precautionary principle (PP) applied to environmental policy stipulates that, in the presence of uncertainty, society must take robust preventive action to guard against worst-case outcomes. It follows that the higher the degree of uncertainty, the more aggressive this preventive action...

The increasing scarcity of water resources (in terms of quantity and quality) is one of the most pervasive natural resource allocation issues facing development planners throughout the world.This problem is especially prevalent in less developed countries where the management of this valuable...

Non-point-source (NPS) pollution refers to a form of pollution in which neither the source nor the size of specific emissions can be observed or identified with sufficient accuracy. In NPS pollution the ambient concentration of pollutants associated with the individually unobserved emissions is...

The precautionary principle (PP) applied to environmental policy stipulates that, in the presence of physical uncertainty, society must take robust preventive action to guard against worst-case outcomes. It follows that the higher the degree of uncertainty, the more aggressive this preventive...
