In this paper we study a basic model of economic growth where we integrate a zero-dimensional energy balance model of the Earth. The albedo of the Earth is the piecewise smooth function of the average surface temperature, thus, taking into account possible feedback effects of a higher...

Discounting in the presence of catastrophic risk is a hotly debated issue, in particular with respect to climate change. Many scientists and laymen concerned with potentially catastrophic impacts feel that if an increase in the discount rate drastically increases the likelihood of catastrophic...

In this paper I explore a model where citizens of a country vulnerable to damages from climate change may migrate to a second country, from which a steady stream of greenhouse gases occur. If this migration imposes costs on the emitting country, then migration induces a sort of pseudo carbon...
