This week, I will be working in Waterloo, and give a talk on on Causal Inference and Counterfactuals with Optimal Transport, With Applications in Fairness and Discrimination (based on our paper on Optimal Transport for Counterfactual Estimation, with Emmanuel Flachaire and Ewen Gallic, as well as a more recent one on Parametric Fair Projection with Statistical Guarantees, with François Hu and Philipp Ratz).
