This paper examines whether the renminbi (RMB) has supplanted the US dollar as the major anchor currency in the currency baskets of East Asian economies. It systematically demonstrates that existing techniques to address the problem of severe multicollinearity in estimations of the...

An Asian Currency Unit (ACU) index is constructed using an alternative procedure which minimizes a basket or portfolio of assets expressed in terms of national currencies. Using this estimated ACU Index and an ACU Deviation Indicator, the main finding of this study based on the current...

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,...

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,...
