CBO investigation satisfy all these standards however, only return in order to 1979 and so are sensitive to form of methodological options. (See the Appendix.) The fresh new historical Census nearest and dearest money data collection and you may Piketty-Saez greatest-money attention data shelter longer period but have fun with quicker total money procedures and don’t to evolve getting alterations in home proportions and you can composition. Using a total money size, just like the Piketty, Saez, and you may Zucman would within their statistics to the shipments away from federal earnings, addresses specific items however, brings up other people because of the number of presumptions inside it.
The increased loss of Common Success
