The consequences of the 2°C climate target and the implicitly imposed ceiling on CO2 have been analyzed in several studies. We use an endogenous growth model with a ceiling and an abatement option to study the effect of the ceiling on the allocation of limited funds for R&D, abatement and...

A survey of the economic impact of climate change and the marginal damage costs shows that carbon dioxide emissions are a negative externality. The estimated Pigou tax and its growth rate are too low to justify the climate policy targets set by political leaders. A lower discount rate or greater...

Complex dynamic systems can undergo changes in feedbacks between system components causing a rapid and persistent shift in system behavior (“regime shifts”), and potentially reduce welfare from declining provision of important ecosystem services. In this paper, we provide an analytical...

We extend an open economy Ramsey model to include the technology gap to the world technology frontier. The setting is a middle income country with productivity growth driven by technology adoption and foreign capital goods stimulating spillover and catching up. The interaction of technology...

The adaptation vs. mitigation dilemma is considered by analyzing a simple dynamic model of managing a polluting process subject to the risk of abrupt occurrences of harmful events. The occurrence hazard can be mitigated by reducing the polluting emissions, while the occurrence damage can be...

There is a growing concern that risks of disease outbreak and pandemics are increasing over time. We consider optimal investments in prevention before an outbreak using an endogenous risk approach within an optimal control setting. Using the threat of pandemic influenza as an illustrative...

This article proposes a theoretical framework to investigate economic robustness to exogenous shocks such as natural disasters. It is based on a dynamic model that represents a regional economy as a network of production units through the disaggregation of sector-scale input–output tables....

In a general equilibrium model of the world economy, we develop a two-dimensional energy balance climate model featuring heat diffusion and anthropogenic forcing driven by global fossil fuel use across the sphere of the Earth. This introduces an endogenous location dependent temperature...

We study the effect of environmental risk on the extraction of a common resource. Using a dynamic and non-cooperative game in which an environmental event impacts the renewability and the quality of the resource, we show that the anticipation of such an event has an ambiguous effect on...

We design a global refunding scheme as a new international approach to address climate change. Participating in the global refunding system requires an initial payment. It allows each country to set its carbon emission tax, while aggregate tax revenues are partially refunded to member countries...
