Suppose you are central bank governor of a country

Suppose you are central bank governor of a country which is experiencing inflation
of 100% per month. You have two economic advisors. One advisor tells you that in
order to increase seignorage you ought to raise the money growth rate. The other
advisor tells you that in order to increase seignorage you ought to reduce the money
growth rate.
(a) Explain the concept of seignorage, both in words and formally (e.g. algebraically). 
(b) Which of the two recommendations is correct? Why? (Hint: look up the
concept of the "Laffer curve" and use it to answer this question.)
