Optimal Transport in Economics
Amine Fahli, Alfred Galichon
Optimal transport provides a common language for allocation, equilibrium, computation, and inference. Its primal problem assigns mass or agents, while its dual variables admit econ…
Repeated Matching Games: An Empirical Framework
Pauline Corblet, Jeremy Fox, Alfred Galichon
We introduce a model of dynamic matching with transferable utility, extending the static model of Shapley and Shubik (1971). Forward-looking agents have individual states that evol…
Matching under Imperfectly Transferable Utility
Alfred Galichon, Simon Weber
In this paper, we examine matching models with imperfectly transferable utility (ITU). We provide motivating examples, discuss the theoretical foundations of ITU matching models an…
The matching problem with linear transfers is equivalent to a hide-and-seek game
Alfred Galichon, Antoine Jacquet
Matching problems with linearly transferable utility (LTU) generalize the well-studied transferable utility (TU) case by relaxing the assumption that utility is transferred one-for…
Existence of a Competitive Equilibrium with Substitutes, with Applications to Matching and Discrete Choice Models
Liang Chen, Eugene Choo, Alfred Galichon +1
We propose new results for the existence and uniqueness of a general nonparametric and nonseparable competitive equilibrium with substitutes. These results ensure the invertibility…
Monotone comparative statics for submodular functions, with an application to aggregated deferred acceptance
Alfred Galichon, Yu-Wei Hsieh, Maxime Sylvestre
We propose monotone comparative statics results for maximizers of submodular functions, as opposed to maximizers of supermodular functions as in the classical theory put forth by V…
