alas, there is a role for net present value and business plans in
static neoclassical econ. Assume we have so-called "rational
expectations" (perfect foresight with some random error thrown in).
Then the future is really nothing but a projection of the present.
Differences in time period are equivalent to distances in space.
Voila! dynamics have been reduced to statics.

and in finance, the hard-core versions of the "efficient markets
hypothesis" are based on rational expectations.
