When Shareholders Are Creditors: Effects of the Simultaneous Holding of Equity and Debt by Non-commercial Banking Institutions

Authors

Format
Journal Article
Journal
The Review of Financial Studies

This article provides a comprehensive analysis of a new and increasingly important phenomenon: the simultaneous holding of both equity and debt claims of the same company by non-commercial banking institutions ("dual holders"). The presence of dual holders offers a unique opportunity to assess the existence and magnitude of shareholder-creditor conflicts. We find that syndicated loans with dual holder participation have loan yield spreads that are 18–32 bps lower than those without. The difference remains economically significant after controlling for the selection effect.

Pharmaceutical Price Discrimination and Social Welfare

Capitalism and Society

Price discrimination is an extremely common type of pricing strategy engaged in by virtually every business with some discretionary pricing power. The issue of whether price discrimination reduces or increases social welfare has been considered by economists since at least 1920. At that time, it was demonstrated that, under certain (restrictive) conditions, price discrimination will reduce social welfare.

The Connected Customer

Jacob Goldenberg, Sangman Han, and Donald Lehmann discuss the critical role of "social hubs" in social systems (i.e., individuals with an exceptionally large number of social ties). They point to the importance of identifying such social hubs for accelerating the diffusion of products.

Global Customer Management Programs: How to Make Them Really Work

Authors

Journal Article
Journal
California Management Review

Identifying the right business model for addressing global customers and formalizing that model into a global customer management program is a key task for any firm with global aspirations. The key success factor is embedding the program firmly within the firm's corporate strategy. Simply leveraging domestic or regional account management into such a program will not deliver the desired results. Based on extensive research with a global company database, this article presents a framework for successfully introducing a global customer management program.

Activist arbitrage: A study of open-ending attempts of closed-end funds

Journal Article

Journal of Financial Economics

This paper documents frequent attempts by activist arbitrageurs to open-end discounted closed-end funds, particularly after the 1992 proxy reform which reduced the costs of communication among shareholders. Open-ending attempts have a substantial effect on discounts, reducing them, on average, to half of their original level. The size of the discount is a major determinant of whether a fund gets attacked. Other important factors include the costs of communication among shareholders and the governance structure of the targeted fund.

Hedge Fund Activism: A Review

Foundations and Trends in Finance

This article reviews shareholder activism by hedge funds. We first describe the nature and characteristics of hedge fund activism, including the objectives, tactics, and choices of target companies. We then analyze possible value creation brought about by activist hedge funds, both for shareholders in the target companies and for investors in the hedge funds. The evidence generally supports the view that hedge fund activism creates value for shareholders by effectively influencing the governance, capital structure decisions, and operating performance of target firms.

Creativity, Brands, and the Ritual Process: Confrontation and Resolution in Advertising Agencies

Journal
Culture and Organization

The intensity of modern business has increased pressure for innovation, which places greater emphasis on creativity. This article explores one of the central sites of creativity in the American corporate world, the advertising agency. We examine how creativity in agencies is managed, controlled, and channeled to produce advertisements. We contend that the brand advertised and the agency’s creative collaborations have properties of ritual symbols and that rituals mediate tension inherent in two forces, stability and change, which define the brand and the advertising collaboration.

Signaling Firm Value to Active Investors

Authors

Format
Journal Article
Journal
Review of Accounting Studies

Active investors provide entrepreneurs with risk-sharing and value-adding effort, e.g., in form of advising, networking and monitoring. However, holdup problems may create a conflict between two key objectives for high-quality entrepreneurs: to elicit investor effort and to credibly signal their firm type by retaining shares. As a result, pooling of startup firms of different types may arise, in particular when investor effort is essential. More established firms, with access to multiple signals, can always realize both of these objectives.
