Abstract

How do social norms travel across the US? Evidence from CSR activism

We examine whether the social norms that institutional investors are exposed to in their home locality affect their willingness to support corporate social responsibility (CSR) activism in other parts of the US. We find that the shareholdings of non-local institutional investors from localities with strong CSR norms are positively related to the likelihood that a firm is targeted by a CSR-related shareholder proposal, the percentage of votes cast in favor of that proposal, and the likelihood that the proposal is ultimately successful. Further, we find that these relations are stronger if the target firm is located in an area with weak CSR norms. Thus, our results suggest that non-local institutional investors are influenced by the social attitudes they face at home, and these local norms can affect their support for CSR activism aimed at investees outside their home region. In particular, institutional investors from areas with strong CSR norms act as a conduit for promoting better CSR practices, especially for investees located in areas with weak CSR norms.

Abstract (Japanese)

本稿では,わが国独自の自己株式取得方法であるToSTNeT買付を利用した,内部者の機会主義的行動を検証している.本稿の検証からは,自社株買い企業の中には,自社の取締役等の特定の大株主が有利に保有株を売却することを可能にするために,意図的に買付方法不明で自己株式の取得枠設定だけを先に公表して株価を吊り上げ,その後にToSTNeT買付を実施して高値で自己株式を取得している企業があることを示唆する強い証拠が得られている.

このような特定の内部者だけに利益を享受させる企業の行動は,会社財産の不当な社外流出に該当しかねず,株主平等の原則にも抵触し得る非倫理的な行為といえる.現行のToSTNeT買付制度には,内部者の機会主義的行動を許す余地が残されており,今後改善される必要があるであろう.


Abstract

Auction or ToSTNeT? A Guessing Game for Share Repurchases in Japan

In this paper, we investigate share repurchases executed in a unique market in Japan, Tokyo Stock Exchange Trading Network (ToSTNeT). This network is an alternative to open market repurchases (OMR) that allows buying firms to repurchase shares during off-auction hours, which are normally about 16 hours from the announcement of share repurchase program via ToSTNeT to the execution of share repurchase.

Recently, a few high profile cases have brought to light a potential loophole in the existing share repurchase program that are executed via ToSTNeT. In particular, we find that while most buying firms disclose the use of ToSTNeT when the announcement of share repurchase program is made, some buying firms do not disclose the use of ToSTNeT until a few days after announcing the share repurchase program. We classified buying firms that do not disclose the use of ToSTNeT at the time of share repurchase program is announced as “hidden ToSTNeT”. Overall, we find that buying firms that use hidden ToSTNeT experience temporary sharp share price increases, consistent with the market perceiving share repurchases as good news. However, when buying firms subsequently reveal that ToSTNeT will be used to repurchase shares, share prices immediately plummet. As the repurchase price is fixed at the closing price of the preceding day, selling firms are able to sell the shares at the inflated price (the price before the use of ToSTNeT is disclosed), thereby making significant profit on the trade. Importantly, we find that in the majority of cases, buying firms that use hidden ToSTNeT repurchase shares from large single investors who are also insiders of the buying firms as they are either executives or the founder of the buying firms.

Abstract

Idea Discovery: An Emerging AI Technique to Fuse Data Intelligence and Human Wisdom

Traditional knowledge discovery is a computer-based data mining process. However, the mining results are usually constrained by selected input data. Specifically, some implicit knowledge are not digitized in the data. Besides, how to make knowledge creation from knowledge discovery is a very interesting and challenging work. In this talk, I will present a new emerging technique, Idea Discovery [1], which is a human-centric technique to capture and fuse both data intelligence [2] and human wisdom [3], thereby further making knowledge creation for the best decision support.

Abstract

Internet of Things, Big Data, and Smart Applications

The Internet of Things (IoT) refers to uniquely identifiable objects as well as their virtual representations in an Internet-like structure. It is related to a number of disciplines and technologies that enable the Internet to reach out into the real world of physical objects and their environments. It has been hailed as the most potentially disruptive technological revolution of our lifetime after the Web and mobile accessibility. It becomes even more promising with smart applications like smart cities, smart Grid, smart factories, smart buildings, smart homes, and smart cars. On the other hand, Big Data is a broad term for data sets so large or complex that traditional data processing technologies are inadequate. It has recently been considered as a technology and become a very active research area primarily involving topics related to machine learning, database, and distributed computing. It has been claimed that “the success or failure of the Internet of Things hinges on Big Data”. Based on many years of first-hand experience, this talk will provide an overview of IoT and Big Data, including state-of-the-art and future trends, with a focus on how IoT and Big Data are linked with and applied in various industrial domains and societies.
