Dispersion in analysts' forecasts: does it make a difference?
Get PDFFinancial analysts are an important group of information intermediaries in the capital markets. Their reports, including both earnings forecasts and stock recommendations, are widely transmitted and have a significant impact on stock prices (Womack 1996; Lys and Sohn 1990, among others). Empirical accounting research frequently relies on analysts' forecasts to construct proxies for variables of interest. For example, the error in mean forecast is used as a proxy for earnings surprise (e.g., Brown et al.1987; Wiedman 1996; Bamber et al.1997). More recent papers provide evidence that the mean consensus forecast is used as a benchmark for evaluating firm performance. (Degeorge et al. 1999; Kasznik and McNichols 2002; Lopez and Rees 2002).
Another stream of research uses the forecast dispersion as a proxy for the uncertainty or the degree of consensus among analysts and focuses on the information properties of analysts (e.g., Daley et al. 1988; Ziebart 1990; Imhoff and Lobo 1992; Lang and Lundholm 1996; Barron and Stuerke 1998; Barron et al. 1998). In this paper I combine the two streams of research, and investigate how lack of consensus changes the information environment of analysts and whether the markets perceive this change. More specifically, I investigate the amount of private information in a divergent earnings estimate (i.e. one that is above or below the consensus), whether the markets react to it at either the time of the forecast release, at the realization of actual earnings, and whether Regulation Fair Disclosure has changed the information environment differently for high and low dispersion firms
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
Walking the Talk? Jesuit Universities and Fossil Fuel Investments
Get PDFThe student-led fossil fuel divestment (FFD) movement urges universities to remove investments in fossil fuel firms from their endowment portfolios to inspire reductions in carbon emissions and help control climate change. This article explores the movement in U.S.-based Jesuit universities by documenting their endowment size, current divestment status, and rationale for or against divesting. These institutions held a total of US$13.8 billion in their endowments as of 2019, making their investment decisions relevant and material. The article in general examines the alignment of divestment actions with the commitments of Jesuit universities to environmental stewardship and social justice as expressed in their mission statements and Pope Francis’s encyclical Laudato Si’. Two out of the 27 Jesuit universities in the U.S., namely, Georgetown and Seattle University, were already committed to FFD by April 2020; after accounting for branch campuses, this represents a commitment of 13.3% among all U.S.-based Jesuit universities. This is appreciably higher than the 4.12% divestment rate among all private 4-year universities in the United States. Each of the 27 U.S.-based Jesuit universities was contacted to verify their endowment size, divestment status, and position on FFD. The 13 who responded stated their commitment to environmental protection and sustainability, and some reported their rationale for or against divesting. Results suggest that the investment strategies of Jesuit universities are a “work in progress,” and are likely to evolve as they align with their common Roman Catholic and Jesuit identity and mission. The reasons stated for deciding not to divest, moreover, are consistent with previous literature. A second article in this issue of the Journal of Management for Global Sustainability explores those reasons in detail and broadens the theme of divesting to encompass any organization
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
The role of corporate governance in meeting or beating analysts' forecast
No full textMeeting or beating analysts' forecasts is a topic of considerable interest in the academic and business communities. Some studies indicate a favorable market response when firms meet or beat analysts' earnings forecasts, but others suggest managers opportunistically manage earnings to achieve earnings targets. We investigate the relation between corporate governance mechanisms and meeting or exceeding analysts' expectations and find that attributes of corporate governance are related to the likelihood of consistently meeting or exceeding consensus forecasts. We extend current literature by showing that some attributes of strong corporate governance mechanisms lower agency costs associated with consistently meeting or beating analysts' expectations. We also find that compensation committees reward managers for consistently meeting or beating analysts' forecasts.
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
