doi:10.7866/HPE-RPE.25.2.4engRodrigo Sauco, FernandoMillionaires on the Run? Taxation of the Rich and Induced Mobility: A Literature ReviewART-2025-144881The main goal of this paper is to evaluate, from an economics perspective, the growing literature on the possible tax-induced residential mobility of high-income and high-net-worth individuals. This literature is dominated by the estimation of one parameter: migration elasticity in response to changes in net-of-tax income. The considerable heterogeneity of estimations of this elasticity warns against drawing any overall conclusions without considering and evaluating the institutional and economic conditions and methodological options influencing each specific estimation. While keeping this caveat in mind, we offer some final recommendations for public decision-makers who hope to offer differentiating tax policies targeting taxpayers in the top wealth and income bracket or favouring specific professional profiles.2025http://zaguan.unizar.es/record/16232610.7866/HPE-RPE.25.2.4http://zaguan.unizar.es/record/162326oai:zaguan.unizar.es:162326info:eu-repo/grantAgreement/ES/DGA/S23-23RHacienda Publica Española 253, 2 (2025), 91-127by-nchttps://creativecommons.org/licenses/by-nc/4.0/deed.esinfo:eu-repo/semantics/openAccess
