A Top-Down Approach to Projecting Market Impacts of Climate Change
Lemoine, D. and S. Kapnick. 2015. Nature Climate Change. doi:10.1038/nclimate2759
To evaluate policies to reduce greenhouse-gas emissions, economic models require estimates of how future climate change will affect well-being. So far, nearly all estimates of the economic impacts of future warming have been developed by combining estimates of impacts in individual sectors of the economy. Recent work has used variation in warming over time and space to produce top-down estimates of how past climate and weather shocks have affected economic output. Here we propose a statistical framework for converting these top-down estimates of past economic costs of regional warming into projections of the economic cost of future global warming. Combining the latest physical climate models, socioeconomic projections, and economic estimates of past impacts, we find that future warming could raise the expected rate of economic growth in richer countries, reduce the expected rate of economic growth in poorer countries, and increase the variability of growth by increasing the climate’s variability. This study suggests we should rethink the focus on global impacts and the use of deterministic frameworks for modelling impacts and policy.
Watch Your Step: Optimal Policy in a Tipping Climate

We investigate the optimal policy response to the possibility of abrupt, irreversible shifts in system dynamics. The welfare cost of a tipping point emerges from the policymaker's response to altered system dynamics. Our policymaker also learns about a threshold's location by observing the system's response in each period. Simulations with a recursive, numerical climate-economy model show that tipping possibilities raise the optimal carbon tax more strongly over time. The resulting policy paths ultimately lower optimal peak warming by up to 0.5 degrees C. Different types of post-tipping shifts in dynamics generate qualitatively different optimal pre-tipping policy paths.

The benefits and costs of increasing solar electricity generation depend on the scale of the increase and on the timeframe over which it occurs. Short-run analyses focus on the cost-effectiveness of incremental increases in solar capacity, holding the rest of the power system fixed. Solar's variability adds value if its power occurs at high-demand times and displaces relatively carbon-intensive generation. Medium-run analyses consider the implications of non-incremental changes in solar capacity. The cost of each installation may fall through experience effects, but the cost of grid integration increases when solar requires ancillary services and fails to displace investment in other types of generation. Long-run analyses consider the role of solar in reaching twenty-first century carbon targets. Solar's contribution depends on the representation of grid integration costs, on the availability of other low-carbon technologies, and on the potential for technological advances. By surveying analyses for different time horizons, this paper begins to connect and integrate a fairly disjointed literature on the economics of solar energy.

Today’s environmental challenges emerge from the interaction between complex social and natural systems. These complex interactions mean that uncertainty about costs and benefits is an inevitably crucial part of policy problems. Derek Lemoine’s research incorporates scientific and economic uncertainty into tractable modeling frameworks. For instance, while we understand that the correct price for greenhouse gas emissions is not zero, the integrated assessment models used to estimate this price have assumed that the climate system evolves smoothly and predictably. Yet we think that the possibility of abrupt changes could be a major part of these emissions' cost. One of Derek's papers therefore builds possible climate tipping points into a benchmark climate-economy model in order to understand how different types of tipping points affect the optimal carbon price.
At the University of Arizona, Derek works on several projects at the intersection of uncertainty, dynamics, and climate change. For instance, he has used economic theory to better understand how to set emission ratings in existing biofuel policies. He has also considered how more stringent climate policies trade off uncertainty about damages from climate change for uncertainty about the cost of reducing emissions. In addition to his work in economics, he has published in top journals in geoscience, forestry, and environmental science. These papers’ topics include statistical analyses of ice core records, methods for learning about actual climate change from global climate models’ simulations, and the energy implications of plug-in hybrid electric vehicles.
Guided by the philosophy that research questions should drive methods, Derek obtained his Ph.D. in 2011 from the interdisciplinary Energy and Resources Group at the University of California, Berkeley. By working in multiple departments, he also obtained a concurrent Master’s in Economics from UC Berkeley and key advising from Agricultural and Resource Economics. His undergraduate degree was in Philosophy and in Integrative Environmental Solutions, from the University of the South in Sewanee, TN. He teaches a graduate class on applied theory approaches to environmental economics. He also teaches a freshman class that introduces core economic concepts through energy and environmental applications.
