"The Fable of the Keiretsu: "Keiretsu" in Keiretsu no Kenkyu"(in Japanese)
Get PDFBasic as it has become to studies of the Japanese economy, the concept of the "Keiretsu" is sheer fiction -- a creature of the academic imagination with no basis in real economic behavior. Almost all scholars writing on the subject use the categorization found in the annual Keiretsu no kenkyu [Research on the Keiretsu]. Published by an otherwise unknown Marxist "research institute" since 1960, the volume purports to sort firms by functional groupings. In fact, it simply sorts them by their principal loan source. If that loan source proxied for some unobserved variable, this sorting might be helpful. In fact, it does not. For example, among keiretsu firms, there is little cross-shareholding. Indeed, the non-financial firms in a given keiretsu hold stock in few other keiretsu firms at all. Although financial firms do buy stock in their debtors, they seem as likely to buy the stock of their non-keiretsu debtors as of keiretsu debtors. The lending patterns of financial firms in a keiretsu are usually uncorrelated, and much the same is true of their shareholding patterns.

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
The Impact of Public Markets Paul Gompers, Anna Kovner, Josh Lerner, and David Scharfstein
No full textThis paper examines how changes in public market signals affected venture capital investing between 1975 and 1998. We find that venture capitalists with the most industry experience increase their investments the most when public market signals become more favorable. Their reaction to an increase is greater than the reaction of venture capital organizations with relatively little industry experience and those with considerable experience but in other industries. The increase in investment rates does not affect the success of these transactions adversely to a significant extent. These findings are consistent with the view that venture capitalists rationally respond to attractive investment opportunities signaled by public market shift
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
Outside Finance, Dominant Investors and Strategic Transparency
Get PDFThis paper studies optimal financial contracts and product market competition under a strategic transparency decision. When firms seeking outside finance resort to actively monitored debt in order to commit against opportunistic behaviour, the dominant lender can influence corporate transparency. More transparency about a firm's competitive position has both strategic advantages and disadvantages: in general, transparency results in higher variability of profits and output. Thus lenders prefer less information dissemination, as this protects firms when in a weak competitive position, while equityholders prefer more disclosure to maximize profitability when in a strong position. We show that bank-controlled firms will be opaque, while shareholder- run firms prefer more transparency. In fact, we can predict a clustering of characteristics associated with bank dominance: opaqueness, low variability of profits, slightly reduced average profits, uncertainty about assets in place, and relatively high financing needs all should be observed jointly for bank controlled firms.corporate governance; transparency; bank finance; product market competition; capital structure
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
Skill vs. Luck in Entrepreneurship and Venture Capital: Evidence from Serial Entrepreneurs
Get PDFThis paper argues that a large component of success in entrepreneurship and venture capital can be attributed to skill. We show that entrepreneurs with a track record of success are more likely to succeed than first time entrepreneurs and those who have previously failed. Funding by more experienced venture capital firms enhances the chance of success, but only for entrepreneurs without a successful track record. Similarly, more experienced venture capitalists are able to identify and invest in first time entrepreneurs who are more likely to become serial entrepreneurs. Investments by venture capitalists in successful serial entrepreneurs generate higher returns for their venture capital investors. This finding provides further support for the role of skill in both entrepreneurship and venture capital.
