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 ...

Household Finance after a Natural Disaster: The Case of Hurricane Katrina
Little is known about how affected residents are able to cope with the fi nancial shock of a natural disaster. We investigate the impact that flooding from a major US hurricane had on household finance. Spikes in credit card borrowing and overall delinquency rates for the most flooded residents are modest in size and short-lived. Greater flooding results in larger reductions in total debt. Lower debt levels appear to be driven by homeowners using flood insurance to repay their mortgages rather than to rebuild. Debt reductions are larger in census tracts where mortgages were likely to be ...

Fair weather or foul? the macroeconomic effects of El Niño
This paper employs a dynamic multi-country framework to analyze the international macroeconomic transmission of El Nio weather shocks. This framework comprises 21 country/region-specific models, estimated over the period 1979Q2 to 2013Q1, and accounts for not only direct exposures of countries to El Nio shocks but also indirect effects through third-markets. We contribute to the climate-macroeconomy literature by exploiting exogenous variation in El Nio weather events over time, and their impact on different regions cross-sectionally, to causatively identify the effects of El Nio shocks on ...

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 ...

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 ...

Housing Market Value Impairment from Future Sea-level Rise Inundation
Sea level rise will pose increased risks to U.S. coastal real estate markets in the coming decades, though the direct economic costs depend on the severity and uncertainty within climate-change scenarios.

Probability Assessments of an Ice-Free Arctic: Comparing Statistical and Climate Model Projections
The downward trend in the amount of Arctic sea ice has a wide range of environmental and economic consequences including important effects on the pace and intensity of global climate change. Based on several decades of satellite data, we provide statistical forecasts of Arctic sea ice extent during the rest of this century. The best fitting statistical model indicates that overall sea ice coverage is declining at an increasing rate. By contrast, average projections from the CMIP5 global climate models foresee a gradual slowing of Arctic sea ice loss even in scenarios with high carbon ...

The Rising Cost of Climate Change: Evidence from the Bond Market
The level of the social discount rate (SDR) is a crucial factor for evaluating the costs ofclimate change. We demonstrate that the equilibrium or steady-state real interest rate isthe fundamental anchor for market-based SDRs. Much recent research has pointed to adecrease in the equilibrium real interest rate since the 1990s. Using new estimates of thisdecline, we document a pronounced downward shift in the entire term structure of SDRsin recent decades. This lower new normal for interest rates and SDRs has substantiallyboosted the estimated economic loss from climate change and the social ...
