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
