US macroannouncements and international asset pricing
研究发现世界市场风险溢价在美国宏观公告日显著，尤其在货币政策公告时，而非公告日则不显著，这对理解国际资产定价和货币政策不确定性有参考价值。
Abstract The world capital asset‐pricing model is the benchmark model in international finance. However, recent research finds that the premium on the world market factor is insignificant. In this paper, we investigate if the world market risk premium is particularly significant on US macroeconomic announcement days. Empirically, we apply the methodology to daily country exchange‐traded funds. Our findings suggest that although the world market risk premium is insignificant on nonannouncement days, it is strongly significant on US macroeconomic announcement days. In addition, we find that US monetary policy announcements are the most important macroeconomic announcements to drive the world market risk premium. Our findings are consistent with the notion of monetary policy uncertainty and the empirical literature that connects policy uncertainty with systematic risk.
