Stock Returns and the Tone of Marketplace Information: Does Context Matter?
No full textThe author provides empirical evidence that marketplace context matters for understanding stock price behavior. Investor sentiment, as measured by the informational tone of stock market reports from the Wall Street Journal and Bloomberg News outlets, is compared across 2 classification dictionaries: the Harvard General Inquirer IV-4 dictionary and the financial context-specific dictionary of Loughran and McDonald [2011 Loughran, T., and B. McDonald. “When Is a Liability Not a Liability? Textual Analysis, Dictionaries and 10-Ks.” Journal of Finance, 66, (2011), pp. 35–65.[Crossref], [Web of Science ®], [Google Scholar]]. Empirical analyses find a negative relationship between measures of investor pessimism and real stock returns. However, this relationship is strongest and statistically significant only for the context-specific measures. The results suggest that investor sentiment based on contextualized information is able to explain medium- to longer-term swings in aggregate stock prices. This, in turn, implies that investor interpretation of stock market information may not unfold in mechanical ways
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
Our Economic Times: Evaluating Expansionary Policies

Believe it or not, U.S. presidents and the Federal Reserve Bank neither create nor destroy U.S. jobs. Sure, they can set tax rates and borrowing rates and channel funding to various institutions, but they do not - Republican or Democrat, Bernanke or other - dictate the ebbs and flows of our economy..
Our Economic Times: Dodd-Frank on its Way Out?
No full textThis column was published in Savannah Morning News.
Either we have forgotten which sector of the economy brought global markets to their knees in 2008, or we have succumbed to a disastrously distorted incentive structure within the political sphere. Six years after bets gone bad at the largest financial institutions catalyzed the Great Recession in the U.S. (and abroad), policymakers have taken yet another step to gut the once spirited landmark legislation known as the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Less than two weeks into their 2015 tenure, Congress took steps to weaken the act, once thought to be a critical piece of financial market legislation aimed at avoiding future financial panic and the possibility that U..

Our Economic Times: The Fanciful World of Expansionary Austerity
No full textThis news article was published in Savannah Morning News.
The policy debate surrounding the developed world’s economic growth prospects is alive and well - OK, maybe just alive. Somehow, there remains a slice of popular discourse in the U.S. currently promoting the promise of austerity measures as an engine for growth. And, on the contrary, there are those convinced of its impotence. With the wave of politically infused ideologies the world over, there is no hard and fast resolution to this issue and how it applies to current U.S. fiscal and economic policy..
