摘要:Policymakers in two eras of globalization faced the same "trilemma" of difficult
macroeconomic policy trade-offs. Comparing the early years of the 20th century
with the current era of globalization, the author finds that it is not possible
for a government simultaneously to peg the exchange rate, keep an open capital
market, and enjoy monetary policy autonomy. He draws lessons for today's
policymakers.
