This article considers price formation and quantity setting of a capacity-c
onstrained risk-neutral firm facing uncertain demand. It is shown that the
optimal price of a price-setting risk-neutral monopolist decreases with dem
and uncertainty. With a strictly convex demand function expected profits in
crease with uncertainty for a quantity-setting monopolist whereas expected
profits decrease for a price-setting monopolist. Furthermore, similar resul
ts on the effect of uncertainty are derived for a differentiated goods indu
stry.
