Environmental Economics Agricultural Economics Climate Change & Adaptation Policy Evaluation

I am a PhD candidate in economics at the Université du Québec à Montréal and was a Visiting Scholar at INRAE (UMR SMART, Rennes) in 2024. I am an environmental and agricultural economist studying how farmers adapt to climate change and respond to environmental policy, and why these responses so often fall short of their intended goals. I combine structural and dynamic models, computable general equilibrium analysis, and modern causal-inference methods with detailed farm-level and administrative microdata.

Heat Stress, Damage Control, and Structural Maladaptation

Farmers adapt to extreme heat rationally and without delay, yet yields still fall. I show why: when the heat that drives visible pest pressure and the heat that silently determines yield arrive in different growth phases, defensive inputs are aimed at the wrong threat. Across four Quebec crops (1991–2022), barley, the one crop where these windows diverge, reveals this structural maladaptation. Read more →
