Biography

I am an Environmental Economist. I am the Marsili Fellow in Environmental Economics at the CMCC Foundation, European Institute on Economics and the Environment (EIEE) in Milan, Italy, and an Associate Fellow at the Institute for New Economic Thinking (University of Oxford).

Job Market Paper — Mismeasuring Productivity in the Energy Transition
How much of measured electricity productivity growth is actually capital deepening? Using an official BEA deflator revision for identification, I find that US electricity productivity declined rather than stagnated.

My research focuses on productivity and technological change, the effectiveness of climate policy, and the distribution of transition costs and benefits. I use growth accounting, causal inference and quantitative economic modelling to study firms, technologies and households.

I hold a PhD in Economics from Université Paris-Saclay (CentraleSupélec, LGI) and CIRED, an MSc in Environmental Economics from Université Paris-Saclay (AgroParisTech), and a Master in Engineering from Ecole Centrale Paris.

Mismeasuring Productivity in the Energy Transition

Growth accounting identified off an official BEA deflator revision: reattributing 2.8 log points of US electricity productivity growth to capital deepening turns measured stagnation into decline.

Is a fair energy transition possible? Evidence from the French Low-Carbon Strategy

The distributional consequences of environmental policies are a major issue for the public acceptability of energy transitions, as the Yellow-vest demonstrations highlighted. Our objective is to assess the short and mid-term distributional impacts of policy packages on firms and households – rather than of single policy instruments - including carbon taxing, technology adoption subsidies and compensating lump-sum transfers.

Economic and environmental performances of natural gas for heavy trucks: A case study on the French automotive industry supply chain

This paper is a micro-simulation of the adoption of compressed natural gas in heavy-duty vehicles based on real French data on industrial flows in 2018 from the automotive manufacturer Renault. We show that bio-sourced natural gas can be cost-effective for heavy-duty trucks and that detours to reach refuelling stations are key parameters for emissions. That is why fossil natural gas trucks emit more than diesel trucks in real conditions due to low-density of refuelling network.
