Optimal Transport Methods in Economics

"This book is a valuable contribution to a rapidly expanding literature, written by a leader in the field."--James J. Heckman, University of Chicago, winner of the Nobel Prize in economics"Since its inception, the mathematical theory of optimal transportation has served as a secret weapon in the hands of a few scholars for tackling outstanding challenges in economics, ranging from matching and price theory to econometrics and finance. With the publication of Galichon's engaging and accessible text, the secret is revealed to a new generation of students and researchers; I expect much progress to result."--Robert J. McCann, University of Toronto"Economic applications of optimal transport problems have recently flourished. This book, written by one of the best specialists of the field, provides a detailed presentation of the mathematical tools involved, from the abstract foundations of the theory to the practical implementation of optimizing algorithms, with applications ranging from the analysis of the labor market to the resolution of difficult problems in econometrics. For any student or researcher interested in the topic, this is a must-read."--Pierre-André Chiappori, Columbia University"I am aware of no other book on the subject written especially for economists."--Philipp Kircher, University of Edinburgh"Very timely. Until now, there was no focused yet coherent introduction to the subject available to economic theorists."--Rakesh Vohra, University of Pennsylvania
