Thomas Piketty

Are the “inequality” charts simply tracking tax code changes?

The main historical argument made by inequality scholars such as Thomas Piketty, Emmanuel Saez, and Gabriel Zucman asserts that the income and wealth distributions of the United States follow a U-shaped pattern across the past 100 years. According to this narrative, the century began at very high levels of inequality. Intervening events such as the adoption […]

New evidence is undermining the ‘Inequality Scare’

Almost two years have passed since the publication of Thomas Piketty’s Capital in the 21st Century, and the larger genre of economic research on the distribution of wealth has exploded since that time with complementary arguments being advanced by economists Emmanuel Saez and Gabriel Zucman, as well as economic popularizes on the left including Paul Krugman and

Quick thoughts on the new Piketty-Saez-Zucman Income Inequality Study at AEA

Consistent with the recent surge of interest in inequality research, one of the papers generating the most buzz was a new income inequality time series by Thomas Piketty, Emmanuel Saez, and Gabriel Zucman. The paper itself has not been released yet, but its

Fed economists attempt to piketty their own U.S. inequality data

Saez-Zucman, the “Forbes 400,” and a new round of inequality data oddities

When Thomas Piketty’s main inequality chart for the United States came under scrutiny from myself and others over the last year, he was largely non-responsive despite his mounting of a vigorous defense of other areas of his data. (My step-by-step deconstruction of the chart may be found here for reference. Similar criticisms figured prominently in my article

How to manufacture rising inequality, Piketty-style

Since quite a few of Thomas Piketty’s followers are still convinced that he has empirically demonstrated a rise in wealth inequality in the past 30 years, I put together the following breakdown which illustrates how he constructed the famous “U-shape” in his Figure 10.5. As may be readily seen, neither the Kopczuk-Saez (2004) series nor of the

Cherry-Pikettying

My previous posts on the data problems in Piketty’s Capital in the Twenty First Century have focused almost entirely on errors contained within his data charts and files. But what happens when one tries to reconstruct those files? To find out, I conducted a simple experiment using Piketty’s Figure 10.5 – the widely cited depiction of
