It considers (1) measures of international currency use; (2) potential challengers to the dollar; (3) network externalities; and (4) the plausibility of gold and digital currencies, as alternatives to regular currencies. On the one hand, network externalities operate in favor of the status quo: the dollar as the single leading international currency. On the other hand, the danger of abuse of exorbitant privilege - for example, by debasing the currency or repeated use of sanctions - operates in favor of challengers. A good guess is that the dollar will continue to lose market share slowly to others, but will remain in the lead UR - https://www.nber.org/papers/w31476 UR - http://dx.doi.org/10.3386/w31476 ER -
