We provide the planner's solution to a model where households learn from exogenous natural disaster arrivals about arrival rates and spend to mitigate future damages. Mitigation cannot be decentralized due to positive externalities from curtailing aggregate risks. First-best can be implemented...

To study the welfare implications of rising temperature we propose a temperature-augmented long-run risks model that accounts for the interaction between temperature, economic growth and risk. The model simultaneously matches the projected temperature path, the observed consumption growth...

Does a permanent rise in temperature decrease the level or growth rate of GDP in affected countries? Differing answers to this question lead prominent estimates of climate damages to diverge by an order of magnitude. This paper combines indirect evidence on economic growth with new empirical...

Efficient responses to climate change require accurate estimates of both aggregate damages and where and to whom they occur. While specific case studies and simulations have suggested that climate change disproportionately affects the poor, large-scale direct evidence of the magnitude and...

This paper uses international trade data to examine the effects of climate shocks on economic activity. We examine panel models relating the annual growth rate of a country's exports in a particular product category to the country's weather in that year. We find that a poor country being 1...
