Chloé Antoine

Welcome! I am a 2nd-year PhD student in economics at CREST — École Polytechnique, advised by Jean-Marc Bourgeon and Gregory Corcos.

My research interests lie in the fields of environmental economics and international trade, particularly when they apply to agriculture and biodiversity. Currently, my work aims at studying the consequences of agricultural specialisation, with both theoretical and empirical perspectives. I notably enjoy working with geospatial data.

I graduated from Institut Polytechnique de Paris in 2023, where I followed a master's degree in economics. Before that, I studied economics and history at Université Paris Sciences & Lettres as part of a multidisciplinary undergraduate program.

• Agricultural productivity and biodiversity effects: theory and evidence
  with Jean-Marc Bourgeon & José De Sousa
  Agricultural specialization maximizes land use efficiency but it also amplifies pest pressure, thereby requiring heavy pesticide use. This paper evaluates the economic benefits of using an ecological approach that recommends reducing specialization to leverage natural pest control. We develop a model in which the resilience of a farmer's plot is endogenous to the crop and pesticide choices of her neighbors, which is not internalized. We derive the status quo as well as the socially optimal equilibirum distribution of land between crops. Using disaggregated data and novel instrumental variables, we then estimate the impact of diversification on global crop productivity. Results show that crop biodiversity significantly boosts yields of major crops like maize, rice, and wheat.
• Globalization and extensive margins in agriculture
  Anderson and Yotov (2022) introduced the Domestic Extensive Margin (DEM) to identify new trade policy effects using the gravity equation. They defined the DEM as the ratio of products actually produced by a country to the total number that could have been produced. While the denominator can be assumed to be common across countries for manufacturing goods, it varies for agricultural goods due to differences in local climate and soil conditions. For this reason, Anderson and Yotov (2022) did not include agriculture in their analysis. Using agro-ecological data on potential yields, I remedy to this gap. I establish key facts on the agricultural DEM for 130 countries over the past 60 years and quantify the extensive margins effects of globalization for this specific sector.
