This paper considers the allocation of seigniorage in a common currenc
y area with an independent central bank. It is shown that if the centr
al bank retains autonomy in the allocation of seigniorage, inflation w
ill be suboptimally high and taxes and government spending will be sub
optimally low. Constitutionally mandating the rate of money growth wil
l result in optimal inflation, but taxes and government spending will
be too low. As long as consumers do not put too much weight on public
good consumption, relative to private, it is better to constitutionall
y mandate seigniorage allocation shares than the level of money growth
.
