Is Warren Buffett's Commentary on Accounting, Governance, and Investing Practices Reflected in the Investment Decisions and Subsequent Influence of Berkshire Hathaway?
研究了伯克希尔·哈撒韦被投资公司的会计、治理和投资实践是否与巴菲特公开言论一致，以及这些实践是否与伯克希尔的初始选择或后续影响相关。
ABSTRACT We examine (1) whether the accounting, governance, and investing practices of Berkshire Hathaway investees are consistent with Warren Buffett's public statements on what constitutes good accounting, governance, and investing practices and (2) whether these practices are associated with Berkshire's initial “selection” or Buffett's subsequent “influence.” Compared to control firms, we find that Berkshire investees are highly likely to follow Buffett's investment philosophy, somewhat likely to follow his preferred accounting, disclosure, and compensation policies, but unlikely to follow the board-related governance practices that we can measure. Second, we find some evidence that the business practices of future Berkshire investees are more aligned with Buffett's beliefs in the pre-investment period compared to control firms. Third, we find relatively modest evidence that investees improve a few of their business practices subsequent to Berkshire's initial investment. However, and overall, Buffett does not appear to be especially influential in the subsequent accounting, governance, and investing decisions of Berkshire investees, likely because he has already taken into account the attributes he cares most about in the initial investment decision.
