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...

We evaluate the impact of the global financial crisis (GFC) and recent structural changes in the patterns of hoarding international reserves (IR). We confirm that the determinants of IR hoarding evolve with developments in the global economy. During the pre-GFC period of 1999–2006, gross...

We investigate why and how the financial conditions of developing and emerging market countries (peripheral countries) can be affected by the movements in the center economies - the U.S., Japan, the Eurozone, and China. We apply a two-step approach. First, we estimate the sensitivity of...

We examine the open macroeconomic policy choices of developing economies from the perspective of the economic "trilemma" hypothesis. We construct an index of divergence of the three trilemma policy choices, and evaluate its patterns in recent decades. We find that the three dimensions of the...

Using the "trilemma indexes" developed by Aizenman et al. (2010) that measure the extent of achievement in each of the three policy goals in the trilemma--monetary independence, exchange rate stability, and financial openness--we examine how policy configurations affect macroeconomic...
