Dear all,
we are pleased to announce the following seminar at Luiss University.
——— Speaker: Alfred Galichon, New York University Title: Optimal Transport for Economics: Applications and Extensions
When: Thu May 29, 14:30 Where: Via Lisbona 7, 00198 Roma Room: S03A
Abstract: Optimal transport theory has emerged as a unifying geometric framework for a wide range of economic questions that hinge on allocating heterogeneous agents or goods in a cost-efficient way. This talk surveys recent methodological advances and shows how they sharpen three core empirical tools: - Discrete choice models – I will show how viewing demand estimation through the lens of optimal transport delivers transparent identification of taste heterogeneity and suggests computationally efficient estimation algorithms that scale to high-dimensional product spaces. - Matching models – Building on the Monge–Kantorovich formulation, I will discuss equilibrium assignments in labor and marriage markets, highlighting new existence and uniqueness results when complementarities are non-transferable. Optimal transport duality provides constructive characterizations of wage/transfer schedules and illuminates comparative-statics of policy interventions. - Quantile regression and distributional methods – Re-casting quantile regression as an optimal transport problem links conditional quantiles to integral probability metrics. This perspective leads to robust, dependence-aware estimators and facilitates inference on counterfactual distributions, with applications to wage inequality and treatment-effect heterogeneity. Throughout, I will emphasize common geometric intuition, outline open computational challenges, and sketch extensions to dynamic settings and strategic interaction. The overarching goal is to demonstrate how optimal transport offers economists a versatile, tractable, and conceptually coherent toolkit for modeling heterogeneity and market frictions across disparate empirical domains. ———
