Let’s be clear about what must stop: we should never conclude there is ‘no difference’ or ‘no association’ just because a P value is larger than a threshold such as 0.05 or, equivalently, because a confidence interval includes zero. Neither should we conclude that two studies conflict because one had a statistically significant result and the other did not. These errors waste research efforts and misinform policy decisions. …

These and similar errors are widespread. Surveys of hundreds of articles have found that statistically non-significant results are interpreted as indicating ‘no difference’ or ‘no effect’ in around half (see ‘Wrong interpretations’ and Supplementary Information).

附属定款中の強制仲裁条項

 米国で 附属定款の中に強制的な仲裁条項を置くということについて、議論が活発になっています。

 この議論は、比較法の検討としても興味深いです。また、比較法の論点に加えて、会社法や金商法の強行法規性の問題として捉えれば、より本格的な論文のテーマにもなりうるように思います。

 また、この議論は、Sciabacucchi v. SalzbergCyan Inc. v. Beaver County Employees Retirement Fundの影響もあるようで、複眼的に捉えると米国の法制度の特徴が明らかになって面白いように思えます。

Go-Shops Revisited

The Original Study, which examined deals announced in 2006-07, reported that a higher bid emerged during the go-shop period 12.5% of the time (6 instances out of 48 go-shop deals). Using a new database of M&A transactions over the past nine years, we find that the jump rate in the 2010-2018 timeframe was 5.6% (6 out of 108 go-shops), declining to 2.5% (1 out of 40) in the period 2015-2018. The last successful go-shop in our sample occurred approximately three years ago, in January 2016, when II-VI Inc. successfully jumped GaAs Labs’ offer for ANADIGICS, Inc. during a 25-day go-shop period.

As one of us concluded in the Original Study, “go-shop provisions can be a better mousetrap’ in deal structuring – a `win-win’ for both buyer and seller.”  However, over the ensuing decade, a broader set of transactional planners distorted the go-shop technology in ways that achieve their clients’ objectives but no longer satisfy broader corporate law objectives of promoting allocational efficiency in the M&A marketplace.

株式買取請求権と株価——Verition Partners v. Aruba Networks

 Verition Partners v. Aruba Networks事件は、衡平法裁判所から、最高裁判所に上訴されたのですが、この事件について、Jesse M. Fried先生らがamicus briefを提出しています。

 最高裁での口頭弁論は、2019年3月27日のようです。

 最高裁の判断は、株式買取請求権と株価の関係について考えるいい材料になりそうです。

Jack Bogle (1929–2019)

RIP

Bloomberg writes:

Bogle founded Valley Forge, Pennsylvania-based Vanguard in 1974. Investors attracted to its low fees helped the firm overtake American Funds, managed by Los Angeles-based Capital Group Inc., in 2008 as the biggest U.S. stock and bond fund manager. Vanguard has $4.9 trillion in assets under management.
