Choosing this alternative is equivalent to receiving its NPV in cash today. Because NPV is expressed in terms of cash today, using the NPV decision rule is a simple way to apply the Valuation Principle. Decisions that increase wealth are superior to those that decrease wealth. We don’t need to know anything about the investor’s preferences to reach this conclusion. As long as we have correctly captured all of the cash flows of a project, being wealthier increases our options and makes us better off, whatever our preferences are. We now look at some common ways the NPV decision rule is applied in practice. Accepting or Rejecting a Project. A common financial decision is whether to accept or reject a project. Because rejecting the project generally has NPV 0 (there are no new costs or benefits from not doing the project), the NPV decision rule implies that we should ◗ accept positive-NPV projects, because accepting them is equivalent to receiving their NPV in cash today, and ◗ reject negati...
