Income Distributions: A New Model<277:IDANM>2.0.CO;2-X
p. 277-294

This paper endeavors to present a simple model to explain the frequency distribution of income by adding "birth and death" considerations to the more usual random shock system type of model.

A tentative method of fitting such curves is suggested and the values of the parameters discussed.
