The study reported here uses a population ecology approach to examine wheth
er bureaucratic rules breed more rules. Hypotheses about the birth rate of
bureaucratic rules are derived and tested with time series data on rule pro
duction in a large U.S. research university. Results show that the rate of
rule production declines with the number of rules in a rule population over
time. The results support organizational learning theories: by expanding t
he number of rules, organizations increasingly respond to environmental cha
llenges in a programmed way, reducing organizational experiences with new s
ituations, inhibiting organizational learning, and thereby eliminating a ma
in impetus for making more rules. Radical bureaucratization theories, howev
er, are not supported.(.)
