“Unfunded liabilities are ordinarily imputed given some preset long term interest condition ~ so, what is it?”
Social Security and Medicare trustees use a real (inflation-adjusted) interest rate of 2.9% over the long term since that’s been the average amount of interest paid on long-term U.S. Treasury bills.
Germany is paying NEGATIVE INTEREST ~ so that means their unfunded liabilities are good to have since they make money on them, right? (using that as example of why present value analysis, although sending a message, isn't really all that truthful).
