Minority Blocks and Takeover Premia
No full textThis paper analyses takeovers of companies owned by atomistic shareholders and by one minority blockholder, all of whom can only decide to tender or retain their shares. As private benefit extraction is inefficient, the posttakeover share value increases with the bidder's shareholdings. In a successful takeover, the blockholder tenders all his shares and the small shareholders tender the amount needed so that the posttakeover share value matches the bid price. Compared to a fully dispersed target company, the bidder may have to offer a higher price either to win the blockholder's support or to attract enough shares from small shareholders
Why Higher Takeover Premia Protect Minority Shareholders
No full textPosttakeover moral hazard by the acquirer and free-riding by the target shareholders lead the former to buy as few shares as necessary to gain control. As moral hazard is most severe under low ownership concentration, inefficiencies arise in successful takeovers. Moreover, share supply is shown to be upward-sloping. Rules promoting ownership concentration limit both agency costs and the occurrence of takeovers. One share-one vote and simple majority are generally not optimal, and socially optimal rules need not emerge through private contracting
Agency conflicts in public and negotiated transfers of corporate control
No full textWe analyze control transfers in firms with a dominant minority blockholder and
otherwise dispersed owners, and show that the transaction mode is important.
Negotiated block trades preserve a low level of ownership concentration, inducing
more inefficient extraction of private benefits. In contrast, public acquisitions increase
ownership concentration, resulting in fewer private benefits and higher firm
value. Within our model, the incumbent and new controlling party prefer to trade
the block because of the dispersed shareholders’ free-riding behavior. We also explore
the regulatory implications of this agency problem and its impact on the terms of block trade
Large Shareholders, Monitoring, and the Value of the Firm
No full textWe propose that dispersed outside ownership and the resulting managerial discretion come with costs but also with benefits. Even when tight control by shareholders is ex post efficient, it constitutes ex ante an expropriation threat that reduces managerial initiative and noncontractible investments. In addition, we show that equity implements state contingent control, a feature usually associated with debt. Finally, we demonstrate that monitoring, and hence ownership concentration, may conflict with performance-based incentive schemes
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
