Discussion of “Are voluntary disclosures that disavow the reliability of mandated fair value information informative or opportunistic?”
Get PDFBlacconiere, Frederickson, Johnson, and Lewis identify an interesting disclosure and add to our understanding of firm disclosure of option expense. The disclosure is more nuanced than is suggested by the term “disavowal”. Some disclosures are weak, almost tautological “not necessarily … reliable” statements, whereas others are straightforward statements about the “subjective nature” of the inputs to the option valuation model. The “not necessarily … reliable” language largely disappears after SFAS 123R, while stronger language persists. A striking finding in BFJL is lack of opportunism in disavowals, but I suggest that it is preliminary to conclude that there is no opportunism
The Relation Between Reporting Quality and Financing and Investment: Evidence from Changes in Financing Capacity
Get PDFWe use changes in the value of a firm's real estate assets as an exogenous change in a firm's financing capacity to examine (1) the relation between reporting quality and financing and investment conditional on this change, and (2) firms’ reporting quality responses to the change in financing capacity. We find that financing and investment by firms with higher reporting quality is less affected by changes in real estate values than are financing and investment by firms with lower reporting quality. Further, firms increase reporting quality in response to decreases in financing capacity. Our findings contribute to the literature on reporting quality and investment, and on the determinants of reporting quality choices.Sloan School of ManagementWharton Schoo
Do Independent Directors Cause Improvements in Firm Transparency?
Get PDFAlthough recent research documents a positive relation between corporate transparency and the proportion of independent directors, the direction of causality is unclear. We examine a regulatory shock that substantially increased board independence for some firms, and find that information asymmetry, and to some extent management disclosure and financial intermediation, changed at firms affected by this shock. We also examine whether these effects vary as a function of management entrenchment, information processing costs, and required changes to audit committee independence. Our results suggest that firms can alter their corporate transparency to suit the informational demands of a particular board structure
Mandatory Disclosure Quality, Inside Ownership, and Cost of Capital
Get PDFThis paper examines whether and how inside ownership mediates the relation between disclosure quality and the cost of capital. Both ownership and more transparent reporting have the potential to align incentives between managers and investors thereby reducing systematic risk. Employing a large global sample across 35 countries over the 1990–2004 period, we show that country-level disclosure regulation is negatively related to (i) inside ownership, and (ii) firms' implied cost of capital and realised returns. We then introduce ownership into the cost of capital model, and also find a negative relation. These relations extend to the systematic component of the cost of capital, estimated from Fama–French portfolio sorts on ownership and disclosure regulation. Thus, while the direct effect of disclosure on cost of capital is negative, the indirect effect via ownership is positive, consistent with disclosure quality and ownership acting as substitutes. Using path analysis to assess the relative magnitude, our estimates suggest that the direct effect of disclosure quality outweighs the indirect effect by a ratio of about five to one.Wharton SchoolSloan School of Managemen
When Does Information Asymmetry Affect the Cost of Capital?
No full textThis paper examines when information asymmetry among investors affects the cost of capital in excess of standard risk factors. When equity markets are perfectly competitive, information asymmetry has no separate effect on the cost of capital. When markets are imperfect, information asymmetry can have a separate effect on firms’ cost of capital. Consistent with our prediction, we find that information asymmetry has a positive relation with firms’ cost of capital in excess of standard risk factors when markets are imperfect and no relation when markets approximate perfect competition. Overall, our results show that the degree of market competition is an important conditioning variable to consider when examining the relation between information asymmetry and cost of capital
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
