Some empirical data trill illustrate the above theory. 
While this theory deals with property income, the data 
below rather refer to income of property owners, which 
in part is earned income. It is not easy to separate

the earned and unearned income. J Nor are the tiro parts 
independent, so that a convolution of two separately 
derived distributions would not be appropriate. 
In the following, incomes of property owners will be 
treated as a whole. (The distribution of the "profit rate",

convincing. In this study, compensation for risk is 
included in earned income but by it3 nature it is
