holders into four groups ( couples where both have wealth, couples where
one only has wealth, single men and single women ). T he reduction in
sample size impairs the regularity of the data and I have therefore
aggregated the four into two groups : married couples and single
pwcsons.
The calculated Pareto coefficients for income of wealth
owners are much higher than the actual ones { able 1;.
These calculated coefficients correspond more nearly to those of
all income receivers including the wealthless ones -the great
majority. They correspond also more nearly to these of the
conditional income distributions in all wealth classes except the
last three. In fact, if we exclude the open wealth class
fro© the income distribution ( which might perhaps be motivated
by the argument that it is not contained in the calculation of jC
either ) then we get Pareto coefficients entirely in line with
the calculated ones ( Table 1). The motivation is not entirely
convincing and the results are inconclusive.
Since the conditional income distributions in the
wealth classes have been referred to several times, 4 give in the
following data for couples where both husband and wife have wealth.
