Long-Term Macroeconomic Effects of Climate Change: A Cross-Country Analysis
We study the long-term impact of climate change on economic activity across countries, using a stochastic growth model where labor productivity is affected by country-specific climate variables?defined as deviations of temperature and precipitation from their historical norms. Using a panel data set of 174 countries over the years 1960 to 2014, we find that per-capita real output growth is adversely affected by persistent changes in the temperature above or below its historical norm, but we do not obtain any statistically significant effects for changes in precipitation. Our counterfactual ...

Adaptation and the Cost of Rising Temperature for the U.S. Economy
How costly will rising temperature due to climate change be for the U.S. economy? Recent research has used the well-identified response of output to weather to estimate this cost. But agents may adapt to the new climate. We propose a methodology to infer adaptation technology from the heterogeneous responses of output to weather observed currently across the U.S. Our model estimates how much each region has adapted already, and can predict how much each will adapt further after climate change. The size and distribution of losses from climate change vary substantially once adaptation is taken ...

Growth at Risk From Climate Change
How will climate change affect risks to economic activity? Research on climate impacts has tended to focus on effects on the average level of economic growth. I examine whether climate change may make severe contractions in economic activity more likely using quantile regressions linking growth to temperature. The effects of temperature on downside risks to economic growth are large and robust across specifications. These results suggest the growth at risk from climate change is large—climate change may make economic contractions more likely and severe and thereby significantly ...

Climate-related Financial Stability Risks for the United States: Methods and Applications
This report has two objectives: 1. Review the available literature on Climate-Related Financial Stability Risks (CRFSRs) as it pertains to the United States. Specifically, the literature review considers several modeling approaches and aims to 1.1 Identify financial market vulnerabilities (e.g., bank leverage), 1.2 Provide an assessment of those vulnerabilities (high/medium/low) as identified by the current literature, and 1.3 Evaluate the uncertainty surrounding these assessments based on interpretation of the findings and coverage of existing literature (high/low). 2. Identify methodologies ...

The rising tide lifts some interest rates: climate change, natural disasters, and loan pricing
We investigate how corporate loan costs are affected by climate change-related natural disasters. We construct granular measures of borrowers’ exposure to natural disasters and then disentangle the direct effects of disasters from the effects of lenders updating their beliefs about the impact of future disasters. Following a climate change-related disaster, spreads on loans of at-risk, yet unaffected borrowers, spike and are amplified when attention to climate change is high. Weaker borrowers with the most extreme exposure to these disasters suffer the highest increase in spreads. ...

Natural Disasters, Climate Change, and Sovereign Risk
I investigate how natural disasters can exacerbate fiscal vulnerabilities and trigger sovereign defaults. I extend a standard sovereign default model to include disaster risk and calibrate it to a sample of seven Caribbean countries that are frequently hit by hurricanes. I find that disaster risk reduces government's ability to issue debt and that climate change further restricts government's access to financial markets. Next, I show that "disaster clauses", that provide debt-servicing relief, allow governments to borrow more and preserve government's access to financial markets, amid rising ...

Climate Change and Double Materiality in a Micro- and Macroprudential Context
This paper presents a stylized framework of bank risk-taking to help clarify the concept of "double materiality," the idea that supervisory authorities should consider both the risks that banks face from climate change and the impact of a bank’s actions on climate change. The paper shows that the concept of double materiality can be coherently embedded in a microprudential framework, but the practical implications could be quite similar to the implications of a single materiality perspective. The importance of a double materiality perspective becomes larger when one considers ...

Climate Change and the Role of Regulatory Capital: A Stylized Framework for Policy Assessment
This paper presents a stylized framework to assess conceptually how the financial risks of climate change could interact with a regulatory capital regime. We summarize core features of a capital regime such as expected and unexpected losses, regulatory ratios and risk-weighted assets, and minimum requirements and buffers, and then consider where climate-related risk drivers may be relevant. We show that when considering policy implications, it is critically important to be precise about how climate change may impact the loss-generating process for banks and to be clear about the specific ...

Sellin’ in the Rain: Adaptation to Weather and Climate in the Retail Sector
Using novel methodology and proprietary daily store-level sporting goods and apparel brand data, I find that, consistent with long-run adaptation to climate, sales sensitivity to weather declines with historical norms and variability of weather. Short-run adaptation to weather shocks is dominated by changes in what people buy and how they buy it, with little intertemporal substitution. Over four weeks, a one-standard deviation one-day weather shock shifts sales by about 10 percent. While switching between indoor and outdoor stores offsets a small portion of contemporaneous responses to ...
