SUMMARY:Thomas Blanchet (PSE) - “Generalized Pareto Curves: Theory and Applications”\, joint with Juliette Fournier (MIT) and Thomas Piketty (PSE)
DESCRIPTION:\nThe PhD Economics Seminar: Every Thursday at 12:30 pm.\nTime: 12:30 pm – 1:30 pm\nDate: 15th of March 2018\nPlace: Room 3001.\nThomas Blanchet (PSE) – “Generalized Pareto Curves: Theory and Applications”​\, joint with Juliette Fournier (MIT) and Thomas Piketty (PSE) \nAbstract: We define generalized Pareto curves as the curve of inverted Pareto coe cients b(p)\, where b(p) is the ratio between average income or wealth above rank p and the p-th quantile Q(p) (i.e. b(p) = E[X|X > Q(p)]/Q(p)). We use them to characterize entire distributions\, including places like the top where power laws are a good description\, and places further down where they are not. We develop a method to nonparametrically recover the entire distribution based on tabulated income or wealth data as is generally available from tax authorities\, which produces smooth and realistic shapes of generalized Pareto curves. Using detailed tabulations from quasi-exhaustive tax data\, we demonstrate the precision of our method both empirically and analytically. It gives better results than the most commonly used interpolation techniques. Finally\, we use Pareto curves to identify recurring distributional patterns\, and connect those findings to the existing literature that explains observed distributions by random growth models. \n\n\nOrganizers:\nAntoine Bertheau (CREST – ENSAE)\,  Clémence Lenoir (CREST – ENSAE) & Alicia Marguerie (CREST – Polytechnique)\nSponsors:\nCREST\n\nLunch registration:\nfood provided\, no registration \n
