We develop a one-dimemsional energy balance climate model with heat transportation across locations. We introduce the concept of po- tential world GDP at time t, and we introduce, through the temper- ature function, spatial characteristics into the damage function which make damages latitude...

A simpli��ed energy balance climate model is considered with the global mean temperature as the state variable, and an endogenous ice line. The movements of the ice line towards the Poles are associated with damage reservoirs where initial damages are high and then eventually...

We develop a one-dimensional energy balance climate model with heat transportation across locations. We introduce the concept of potential world GDP at time t, and we introduce, through the temperature function, spatial characteristics into the damage function which make damages latitude...

This paper examines robustness in international pollution control emerg- ing from the regulator��s concerns regarding possible misspeci��cation of the natural system that is used to model pollution dynamics. Cooperative and noncooperative robust policy rules...

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

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...

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...

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...
