“How Learning Helps Mitigate the Worst When the Downside of Climate Change is Extreme” (with W. Chang)
There is growing appreciation for the significance of low-probability, high-impact climate outcomes given the speed and scale at which greenhouse gas (GHG) emissions are increasing. Deep uncertainties in the climate system, such as uncertainties in temperature dynamics and the damage function however, make it challenging to hedge against or even assess the risk of catastrophic climate outcomes. In this paper, we examine whether learning efforts that reduce uncertainty in equilibrium climate sensitivity (ECS), the eventual temperature increase in response to changes in GHG concentrations, can enable meaningful midcourse corrections in optimal policy when catastrophic impacts are imminent. For this we simulate learning under three catastrophe-inducing assumptions: the ECS is uncertain and its true value exceeds the range of current scientific beliefs; climate damages are catastrophic at high temperatures; and negative emissions technologies do not materialize at scale for deployment. We find that with learning, the optimal carbon price increases from $130/tCO2 in 2020 to $660/tCO2 in 2050, and further to $3,070/tCO2 in 2100. Learning primarily contributes to welfare improvements through corrections in short-run emission abatement and long-run capital investment decisions. In the short-run, a more stringent carbon abatement policy accelerates the transition to a zero-carbon economy. In the long-run, after global decarbonization is achieved, increased capital investment in anticipation of higher climate damages increases economic output and smoothens consumption.
“Does the Uncertainty about Long-run Temperature Changes Alter Carbon Mitigation Policy?” (with R. Mendelsohn)
The economic literature presents mixed results on whether uncertainty surrounding the long-term temperature response to greenhouse gases justifies more or less near-term mitigation efforts. Using a simple qualitative approach, we explain this debate. Uncertainty about the transient temperature response calls for more immediate mitigation, as it increases the expected welfare loss in the near-term. However, uncertainty about ECS (which pertains to long-term temperatures) calls for less near-term mitigation. Higher ECS values lead to higher temperatures, but with a greater time lag, as it takes a long time to heat up the entire ocean. The present value of welfare is a concave function of ECS. Thus, ECS uncertainty reduces the expected welfare loss and leads to less immediate mitigation.
“The Economics of Coastal Resilience” (with R. Mendelsohn and J. Li)
Economists have made considerable progress examining how sea level rise would affect coastal resilience planning through 2100 (Yohe et al. 1995; 1996; Diaz 2016). The literature suggests protecting urban coastlines and retreating from rural areas globally. However, comparatively little attention has been paid to how best to manage the probability distribution of storm surges. In this paper, we address this gap by introducing a novel integrated assessment model—the Coastal REsilience to Storm Surge (CRESS) simulation model—that determines optimal seawall designs under both sea level rise and storm probability distributions. Building on van Dantzig’s (1956) framework to minimize the sum of expected residual flood damage and seawall costs, we unite natural science, geography, and economics to strike a cost-effective balance with robust risk mitigation. Calibrated to six U.S. Atlantic coast cities, our results show that relatively low seawalls (averaging 1.3 meters above ground) are optimal in these locations, focusing on segments with high expected damage per kilometer. This approach prevents a large share of storm-surge damage while remaining more economical than building tall walls designed for rare but intense storms. Such findings offer a practical and economically efficient alternative to the more precautionary strategies favored by countries like Holland or recommended by agencies such as FEMA. In this sense, CRESS provides a new lens to inform coastal resilience planning around the globe.
“Adapting to Sea Level Rise and Storms” (with R. Mendelsohn and J. Li)
It is well known that cities need to protect themselves from the increasing flood damage by storms as future sea levels rise (SLR). This paper models the dynamics of that adaptation depending on the speed at which SLR increases through 2150. The faster that SLR rises, the more dramatic the increase in flood damage to coastal cities. The optimal adaptation to this dynamic problem is a gradual increase in the extent of urban seawalls. These seawalls average about 1-2 meters in height but they must also gradually move to higher ground as the ocean rises. Flood insurance needs to recognize the protection provided by relatively low seawalls so that this adaptation can take hold in America.
“The Macroeconomic Effect of Temperature Shocks.” (with R. Mendelsohn)
This study reproduces the reported effect of temperature on the growth rate of poor countries (Dell, Jones, Olken 2012) using the same data and method (panel analysis). DJO classify countries as rich or poor based on when they first report real income. Simply classifying whether a country is poor versus rich based on their income each year, leads to the result that temperature shocks do not affect the instantaneous growth rate of either poor or rich countries.
