To learn the economic logic out-of discounting, take into account the $5 mil construction analogy. If for example the $5 billion try invested now (2005), which is $5 mil inside the present really worth. When your project can hold back until 2010, the bucks might possibly be added to a financial where they earns focus, or set in almost every other systems in which it makes instant advantages.
