  The assessing resources dynamics problem, in the context of an economic
system with Gaussian consumption and deterministic productivity, is considered
in this paper. Basically it is presented a discrete time recursive equation
that supports the recourse to the Ornstein-Uhlenbeck diffusion process. Some
assumptions on the regeneration of the process are made, in order to observe
the system equilibrium in what concerns the resources depreciation or
accumulation. The objective of this work is to present a result on the sign of
a ratio that can be used to evaluate harvest procedures in this context.
