Abstract: This paper believes that serious flaws exist in Wang Xiaolu’s calculation of grey income in China for the following reasons: (1) It is not sound methodology to match households with different income levels by using Engel coefficients; (2) The way Wang collected data cannot make up for statistical distortion in the National Bureau of
Statistics’ data; (3)Wang did not provide reasonable explanations for both the income inequality as derived from the estimated income groups and the change in income inequality between the two years he compared; (4)Wang’s calculation of grey income lacks a basic logical foundation.
Key words: grey income, Engel coefficient, income inequality
