The E-axes Forum on Climate Change, Macroeconomics, and Finance

Green Mortgages

João F. Cocco (LBS, CEPR), Bernardo Mendes (LBS) and S. Lakshmi Naaraayanan (LBS, CEPR) examine the true drivers of green financing programs such as green mortgages. Are they real drivers of energy efficiency or marketing instruments?

Temperature, Adaptation, and Local Industry Concentration

Jacopo Ponticelli (Nortwestern University), Qiping Xu (University of Illinois Urbana-Champaign) and Stefan Zeume (University of Illinois Urbana-Champaign, Gies College of Business) show that extreme temperatures between 1980s and 2010s jointly increased energy costs and decreased productivity of small manufacturing plants in the U.S.

Agriculture, Trade, and Global Water Use

Levi Crews (UCLA) shows how global agricultural trade substantially reduces water extraction worldwide by concentrating water-intensive production in water-abundant regions. Yet because water markets are distorted and access is largely open, the water consequences of trade policy depend critically on where production moves, making blanket trade restrictions neither a reliable nor general solution to water scarcity.

Carbon Policy, Inequality, and the Macroeconomics of the Green Transition

Alessandro Sardone (Halle Institute for Economic Research) examines how, despite the EU’s unwavering commitment to net-zero by 2050 and carbon pricing as its central policy instrument, the macroeconomic and distributional consequences of the transition remain poorly understood — particularly how rising energy costs ripple through production, inflation, and household incomes across income groups, and how policy design ultimately shapes these dynamics.

Uncertainty, Tradeoffs, and Credible Climate Policy

Charles Manski (Northwestern University) discusses how credible climate policy requires honestly confronting deep uncertainty, about climate models, economic damages, and discount rates, rather than becoming entrenched in opposing ideologies. Welfare economics provides the rigorous framework needed to transparently quantify the tradeoffs between abatement costs and climate damages.

Climate Change, Adaptation, and Sovereign Risk

Co-Winner of the 2025 E-Axes Forum Research Prize

Sarah Duffy (University of Oxford) studies the implications of sovereign risk for adaptation and therefore the economic losses from natural disasters.
