At the same time, the marginal utility derived from increasing the number of members beyond a certain point falls quickly, indeed may become negative, as in a large organisation agreeing positions becomes exceptionally complicated and time-consuming; beyond a certain level there is no opportunity to find a consensus acceptable to everyone.
This is why I believe that in the long term it is necessary to reduce the number of members of the Monetary Council. As we have also heard, in a country the size of Hungary with a nonfederal system, a 5 to 7 member Monetary Council is thought to be optimal. 2  BIS Review 39/2007  X.
