We examine a monopoly facing an uncertain demand and maximizing profit
s over a two-period horizon. Conditions are developed under which the
firm will find it optimal to ''experiment,'' or adjust initial prices
or quantities away from their myopically optimal level in order to inc
rease the informativeness of observed market outcomes and hence increa
se future profits. We establish conditions under which experimentation
will lead a quantity-setting firm to increase or decrease quantity. F
inally, we develop conditions under which experimenting firms will cho
ose to be either price-setters or quantity-setters.
