Dooley, Folkerts-Landau and Garber (DFG) argue that the present constellation of global exchange-rate arrangements constitutes a revived Bretton-Woods system. DFG ALSO argue that the revived system will be sustainable, despite its large global imbalances. We argue that, to the extent that the...

The origins of the Greek-sovereign debt crisis were the country’s large fiscal and external imbalances. The key factor that abetted those imbalances was the absence of a short-to-medium term adjustment mechanism -- due to perceptions of sovereign bailouts -- in the euro-area that would have...

Owing to dissatisfaction with the IMF’s de jure classification of exchange-rate regimes, a substantial literature has emerged presenting de facto classifications of exchange-rate systems and using the latter classifications to compare performances of alternative regimes in terms of key...

We compare monetary union to flexible exchange rates in an asymmetric, threecountry model with active monetary policy. Unlike the traditional OCA literature, we find that countries with a high degree of nominal wage rigidity benefit from monetary union, specially when they join other, similarly...

The theory of optimum-currency-areas was conceived and developed in three highly influential papers, written by Mundell (1961), McKinnon (1963) and Kenen (1969). Those authors identified characteristics that potential members of a monetary union should ideally possess in order to make it...

We examine the implications of a regional, fixed exchange rate regime for global exchange rate volatility. The concept of the optimum currency area turns out to play an important role. The formation of a regional regime tends to decrease global volatility when countries are symmetric. The...
