Inflation and economic activity in advanced and emerging economies
研究了G7和EM7国家中名义不确定性与宏观经济表现的关系，发现通胀不确定性在多数G7国家会降低产出增长，但在EM7国家影响不一。
Abstract Although the inflation rates have been low in recent years, the uncertainties that put downward pressure on inflation remain the key uncertainties that economies around the world are facing, and they could be unexpectedly persistent. In this article, we investigate the relation between nominal uncertainty and macroeconomic performance in the G7 and EM7 countries. We use a bivariate VARMA GARCH‐in‐mean asymmetric BEKK model to estimate the response of output growth to inflation uncertainty. We find that inflation uncertainty is persistent in most of the G7 and EM7 countries. The uncertainty surrounding future inflation lowers output growth in most of the G7 countries; however, the effect is mixed in the EM7 countries.
