In this paper, we review recent experience with drought in south Flori
da, and report some results of a study of the likely agricultural econ
omic impacts of drought. Our conclusions can be summarized as follows.
(1) Whether a period of low rainfall becomes a ''drought'' in south F
lorida is determined largely by institutional factors. (2) The impacts
of a drought event are dependent on the rules the Water Management Di
strict uses to manage the event. If the rules involve effective reduct
ions in irrigation supply, the financial impacts may be large, but are
sensitive to the way in which cutbacks are imposed. (3) Current droug
ht management regulations do not appear to minimize the short-run cost
of drought. (4) Current policies which seek to minimize the short-run
cost of drought are inconsistent with dynamically-optimal policies.
