AB Distribution functions of annual income of companies are
analyzed based on two company databases. A clear power law
distribution consistent with the Zipf's law can be confirmed
for Japanese companies over more than three decades in income
scale. Similar distributions can be confirmed in some other
countries. It is confirmed that such power laws hold in most of
job categories with slightly modified exponents. An annual
income of a company is about two orders of magnitude smaller
than its total assets, and the growth rate distribution of
income is nearly independent of the income size in contrast to
the case of growth rate of assets. (C) 1999 Published by
