Economic News and the Impact of Trading on Bond Prices
研究宏观经济新闻发布前后交易对政府债券价格的影响，发现公共信息释放加剧了信息不对称，交易的信息作用在新闻发布后显著增强，且与新闻的意外成分和精确度相关。
ABSTRACT This paper studies the impact of trading on government bond prices surrounding the release of macroeconomic news. The results show a significant increase in the informational role of trading following economic announcements, which suggests the release of public information increases the level of information asymmetry in the government bond market. The informational role of trading is greater after announcements with a larger initial price impact, and the relation is associated with the surprise component of the announcement and the precision of the public information. The results provide evidence that government bond order flow reveals fundamental information about riskless rates.
