Abstract:
This study explores whether an increase in the size of firms’ reporting networks (the number of industry peer firms reporting in comparable standards) improves the quality of analysts’ information environments. We exploit the effect of the 2005 mandatory adoption of IFRS around the world on U.S. firms, as IFRS adoption did not directly affect U.S. firms but increased the size of their reporting networks. We document that mandatory IFRS adoption is associated with a significantly larger improvement in the quality of analysts’ information environment for U.S. firms with relatively few domestic industry peers than for other U.S. firms. Further, we show that there is a larger increase in the frequency with which analysts’ research reports for U.S. firms with few domestic peers mention IFRS-adopting EU industry peer firms. Our results provide evidence that mandatory reporting regulations that increase reporting comparability can result in positive information externalities from information network effects.

中文摘要:
本研究探讨企业报告网络(即采用可比准则进行报告的行业内同侪公司数量)的扩大是否会改善分析师信息环境的质量。我们利用2005年全球范围内强制采用国际财务报告准则(IFRS)这一事件对美国公司产生的间接影响展开分析——尽管IFRS的采用并未直接约束美国公司,却显著扩大了其报告网络的规模。研究发现,对于国内同行业可比公司较少的美国企业而言,强制采用IFRS后其分析师信息环境质量的提升幅度显著高于其他美国公司。进一步分析表明,针对这类国内同侪较少的美国公司,分析师在研究报告中提及采用IFRS的欧盟同行业公司的频率也出现更大幅度的增长。我们的研究结果证明,强制性的报告规制通过增强报告可比性,能够借助信息网络效应产生积极的信息外部性。
