The aim of this paper
is to consider a dynamic competitive economic
equilibrium problem in terms of maximization of
utility functions and of excess demand
functions. This equilibrium problem is studied
by means of a time-dependent quasivariational
inequality which is set in the Lebesgue space
. This approach allows us to obtain an existence result of time-dependent equilibrium solutions.
