Brand new historic Census family members earnings research collection and Piketty-Saez best-earnings attention research shelter longer duration however, play with faster comprehensive earnings methods and do not to alter having changes in family size and you will structure. Playing with an even more full earnings level, while the Piketty, Saez, and you will Zucman carry out within statistics to the shipping away from federal income, details specific issues but raises someone else by amount of presumptions involved.

Losing Common Success

Census family members money research demonstrate that on the late 1940s so you’re able to early 70s, revenue across the shipment expanded within nearly a comparable speed.
