We seek in our analysis to understand the forces that favor and oppose currency unions, that is, we extend the classic analysis of optimum currency areas from Mundell (1961). One consideration, not touched on in Mundell?s economic analysis, is that individual currencies are sometimes valued simply out of national pride. One would have expected these nationalistic concerns to be more intense for language than for money, yet most countries willingly use the language of another country, typically the one of a former colonial ruler. Given this acceptance of transplanted language, it is surprising how often people reject currency unions–which sometimes involve the use of another country's currency– simply on the grounds that important countries are supposed to have their own money.
