What would be the consequences if managers of a firm evaluated a project based on its actual dollar cash flows, but used a real rate to discount the cash flows? Would the project be more likely to be accepted, or more likely to be rejected? What kind of error could be committed? Please provide an example of how a project evaluation was affected by inflation considerations, either from your own experience, or do some online search for examples.
