Loss due to a monetary union
■ Fleming-Corden analysis
• Assume there are 3 countries involved: H
(host country), P (potential partner country),
W (rest of the world)
• In order to maintain internal and external
equilibrium, H needs to devalue its currency
relative to W, P needs to revalue its currency
relative to W
• However, if they are in an exchange-rate
union, H and P must devalue or revalue their
currency together
• If countries deprive themselves of rates of
exchange as policy instruments, they impose
on themselves losses that are essentially
losses emanating from enforced departure
from internal balance
