at 100.000), in view of tho higher Dweklisch income level, 
conceals the relevant port of the Pareto distribution 
which pres usably would show a nuch higher Pareto co 
efficient than the income below 100.000 crowns does. 
For 1958/59 (see / /) data ore available on the various 
types of income ofproperty owners in Hollands 1) income 
of unincorporated business and professions 2) unearned 
income, and 3) other income (which is chiefly income 
trou employment). She simple regressions of those three 
incomes on the total income of property owners hove boon 
calculated (fir;. 4). The regression coefficients are 
respectively b„, * 0.30, bp - .1.34 ami u- » 1,01. 
This shows that with increasing wealth the share of 
income derived from property is increasing* 
2ho Pareto coefficient for wealth in 1033/30 is 1.37* 
for income of property owners it is 2.03. If we outlast© 
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). 
Cn the basic of the above information m 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, Va can write for the density of, for
