Methane abatement and geoengineering have a short-lived effect on temperature compared with carbon abatement. Different optimal tax paths for these actions arise in a cost-benefit framework with an unknown temperature threshold where severe and irreversible climate impacts, called a tipping...

This paper builds a framework to quantify the financial stability implications of climate-related transition risk in Colombia. We explore risks imposed on the banking system based on scenarios of an increase in the domestic carbon tax by using bank- and firm-level data. Focusing on the...

This paper explores three possible transmission channels for transition risk shocks to the financial system in Norway. First, we estimate the direct firm-level impact of a substantial increase in domestic carbon prices under severe assumptions. Second, we map the impact of a drastic increase in...

This paper deals with three aspects of spectacular oil price episodes such as the one witnessed in 2008. First, the concept of temporary explosiveness is proposed as an empirical method for capturing this type of behavior. The application of a recently proposed recursive unit root test shows...

We investigate how consumers respond to uncertainty about CO2 emission size. In an incentivized online experiment, participants can acquire a valuable good that emits an unknown amount of CO2. We find that beliefs about emission size are strongly predictive of purchases, even exceeding the...

In this paper we characterize the preferences of a pessimistic social planner concerned with the potential costs of extreme, low-probability climate events. This pessimistic attitude is represented by a recursive optimization criterion à la Hansen and Sargent (1995) that introduces...

The paper clarifies the link between changes in risk aversion and the effect on the consumption discount rate. In a general framework that can cope with various forms of uncertainty, it is shown that the response of the consumption discount rate to a change in risk aversion depends on some...

Recent theoretical work in the economics of climate change has suggested that climate policy is highly sensitive to "fat-tailed" risks of catastrophic outcomes (Weitzman, 2009b). Such risks are suggested to be an inevitable consequence of scientific uncertainty about the effects of increased...

Previous research shows that collective action to avoid a catastrophic threshold, such as a climate "tipping point", is unaffected by uncertainty about the impact of crossing the threshold but that collective action collapses if the location of the threshold is uncertain. Theory suggests that...

Alterations in rainfall patterns and increasing temperatures due to climate change will most likely translate into yield reductions in desirable crops. In this particular context, the object of this paper is to lay down findings and results for projected yield impacts in Morocco using a...
