at 100.000), in view of the higher Swedisch incone level, 
conceals the relevant part of the Pareto distribution 
which presumably would show a much higher Pareto co 
efficient than the income below 100.000 crowns does. 
For 1953/59 (see / / /) data ar*. liable on the various 
types of income ofproperty owners in Holland:1) income 
of unincorporated business and professions 2) unearned 
income, and 3) other income (which is chiefly Income 
from employment). Udie simple regressions of these three 
incomes on the total income of proi>erty owners hove been 
calculated (fig. 4). Tho regression coefficients ore 
respectively b^ ~ 0.30, b 2 = 1.34 and b^ = 1.01. 
Phis shows that with increasing wealth the share of 
income derived from property is increasing. 
flic Pareto coefficient for wealth in 1953/59 is 1.57, 
for income of property owners it is 2.03. If we estimate 
it on the basis of the theory, the coefficient for in 
come would be 1.94 (since k in that year is about 0,31). 
On the basic of the above information we can derive 
theoretical estimates of Pareto coefficients for the above 
mentioned three income types separately from the Pareto 
coefficient for total income of property owners, which in 
turn can be derived from the coefficient for the wealth 
distribution. We can write for the- density of, for
