Comments on "Wealth inequality dynamics in Europe and the United States: Understanding the determinants" by Blanchet and Martinez-Toledano

In this paper, Blanchet and Martinez-Toledano collect, expand, and harmonize wealth and income inequality statistics from prior research and public data sets for the U.S. and E.U. It is a huge undertaking. My comments focus on whether the data permit us at this point to draw these conclusions, or whether differences in methodology and data construction require further reconciliation. While I lean toward the latter judgement, I view this paper and the underlying project as a first, constructive step in an ambitious agenda, with many avenues yet to explore.(c) 2022 Elsevier B.V.
