My friend Barry Eichengreen, together with Marc Flandreau, has written a column in today’s Financial Times, that appears under the headline “Why the euro is unlikely to eclipse the dollar.” The body of the article is a claim that network externalities and tipping points are not important, or perhaps that they once were but no longer are.
The first two steps of their argument are:
(1) a multiple-currency system is the historical norm. The dollar-denominated system that we have experienced for more than 60 years is an aberration, so network externalities (aren’t) important.
(2) The dollar surpassed the pound in the 1924-25, not in 1948, so lags and tipping phenomena are not important.
