Redundancy problem

In international finance, the redundancy problem, also known as the n − 1 problem, is a problem of inequality of the number of policy instruments and the number of targets at the international level, suggested by Robert Mundell in . This problem does not occur at the one-country level. Similarly, if there are n currencies in the world, only n − 1 exchange rates can be "independent" because the exchange rate is a price of one money relative to another. Other rates which are not independent are calculated as cross rate.
