What is an example of a real firm (in the news) pursuing a strategy (or projects) where the project or strategy may not have a positive net present value.For example Walmart is expanding in the United States by building Neighborhood Marts.These are much smaller, more convenient stores that are supposed to win back customers from the "dollar" stores.This is a negative net present value project because these stores will be expensive to operate and will cannibalize sales at the existing Walmart stores.
