Financial Times: ‘Pikkety knoeit met z’n data’
Nu is de Financial Times natuurlijk wel een van de parochieblaadjes van de zittende kapitalistische klasse, maar als ze het hier bij het rechte eind hebben, slaat het wel een deuk in Pikkety’s betoog (om over z’n reputatie nog maar te zwijgen):
…there is little evidence in Prof Piketty’s original sources to bear out the thesis that an increasing share of total wealth is held by the richest few.Prof Piketty, 43, provides detailed sourcing for his estimates of wealth inequality in Europe and the US over the past 200 years. In his spreadsheets, however, there are transcription errors from the original sources and incorrect formulas. It also appears that some of the data are cherry-picked or constructed without an original source.
For example, once the FT cleaned up and simplified the data, the European numbers do not show any tendency towards rising wealth inequality after 1970. An independent specialist in measuring inequality shared the FT’s concerns.
