Empirical studies analyzing the effect of climate change on output growth sometimes neglect economic variables. This yields a biased picture of the growth process and does not represent a good approximation of the true data generating process. Thus, the question arises how valid the results are...

In this paper it is shown that climate models are characterized by uncertainty and its causes are pointed out. It is well known that a higher greenhouse gas concentration raises the radiative forcing of the earth and the physics behind it is well understood. However, as regards the feedback...

In this paper we develop an economic growth model that includes anthropogenic climate change. We include a publicly funded research sector that creates new technologies and simultaneously expands the productivities of existing technologies. The environment is affected by R&D activities both...
