The "monetary trilemma" - the hypothesis that full monetary policy autonomy, exchange rate stability, and financial openness cannot simultaneously be achieved - has long been studied. Recently, holding international reserves (IR) has become an important policy instrument, insuring against...

The value of China's currency, the renminbi (RMB), and the conduct of China's exchange rate policy have generated intense debate in academic and international policy circles. Despite the accumulation of empirical evidence regarding the degree of RMB misalignment over the past few years, the...

We outline new metrics for measuring the trilemma aspects: exchange rate flexibility, monetary independence, and capital account openness, taking into account recent substantial international reserve accumulation. Since 1990, the trilemma variables in emerging markets have converged towards...

This paper extends our previous paper (Aizenman, Chinn, and Ito 2008) and explores some of the unexplored questions. First, we examine the channels through which the trilemma policy configurations affect output volatility. Secondly, we investigate how trilemma policy configurations affect the...

Several alternative measures of effective exchange rates are discussed in the context of their theoretical underpinnings and actual construction. Focusing on contemporary indices and recently developed econometric methods, the empirical characteristics of these differing series are examined,...

Might the dollar eventually follow the precedent of the pound and cede its status as leading international reserve currency? Unlike the last time this question was prominently discussed, ten years ago, there now exists a credible competitor: the euro. This paper econometrically estimates...
