selected goods. All of them are negative,
although we omit the minus sign. Estimates
of both short-run and long-run price elas-
ticities of demand are given where avail-
able. The long run is associated with the
time necessary for consumers to adjust fully
to any given price change. (Note: “N.A."
indicates that no estimate is available.)
