There are enormous conceptual, empirical, and practical problems in
constructing price and quantity indices. All these problems go away if
we consider only very small changes (from year to year, say). But the
moment you start comparing the price "level" today or the output "level"
today to that of a century ago, index-number problems make it very hard
to figure out what you should do (or even if there is anything you can
do) to produce _the_ answer.
