In view of the ambiguities and the deep uncertainty associated with climate change, we study the features of climate change policies that account for spatially structured ambiguity. Ambiguity related to the evolution of the natural system is introduced into a coupled economy-climate model with...

We couple a one-dimensional energy balance climate model with heat transportation across latitudes, with an economic growth model. We derive temperature and damage distributions across locations and optimal taxes on fossil fuels which, in contrast to zero-dimensional Integrated Assessment...

Taking as given that we are consuming too much and that overconsumption leads to environmental degradation, the present paper examines the regulator's choices between informative advertisement and consumptiontaxation. We model overconsumption by considering individuals that care about social...

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 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...

A simplified 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 vanish as the ice...

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...
