This study divides the world into currency zones according to the co-movement of each currency with the key currencies. The dollar zone groups economies that produce well over half of global GDP. The euro zone now includes almost all of Europe and some commodity producers, but remains less than...

This paper investigates the potential impacts of the degree of divergence in open macroeconomic policies in the context of the trilemma hypothesis. Using an index that measures the extent of policy divergence among the three trilemma policy choices — monetary independence, exchange rate...

This paper investigates the potential impacts of the degree of divergence in open macroeconomic policies in the context of the trilemma hypothesis. Using an index that measures the relative policy divergence among the three trilemma policy choices, namely monetary independence, exchange rate...

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 investigates the potential impacts of the degree of divergence in open macroeconomic policies in the context of the trilemma hypothesis. Using an index that measures the relative policy divergence among the three trilemma policy choices, namely monetary independence, exchange rate...

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...

This paper presents a theoretical framework for policy making based on the “impossible trinity” or the “trilemma” hypothesis. A simple optimization model shows that placing more weight in terms of preference for each of the three open macroeconomic policies — exchange rate stability,...

The authors develop a new set of indexes of exchange rate stability, monetary policy independence, and financial market openness as the metrics for the trilemma hypothesis. In their exploration, they take a different and more nuanced approach than the previous indexes developed by Aizenman,...
