But when goods and financial markets are tightly linked, is it problematic if countries unilaterally design their monetary policy rules? Are the stabilization gains from having separate currencies largely squandered in the absence of effective international monetary coordination? We argue that under plausible assumptions the answer is no. Unless risk aversion is very high, lack of coordination in rule setting is a second-order problem compared with the overall gains from macroeconomic stabilization. 收起
