Whether it is necessary to address valuation of impacts depends on whether
monetary values of outcomes are considered important, and whether monetary
values are already well known. Market prices may be sufficient for valuation of
outcomes, however when they are not, due to, for example, a lack of markets or
intertemporal considerations, then various valuation methods can be applied.
Whether valuation methods are applied is often a normative choice to
be made by the analyst and depends on the context in which impact analysis occurs.
