THE SIGMOIDAL INVESTMENT FUNCTION
Full text linkBased on the investment theory of Abel and Eberly (1994), we develop an analytical model of adjustment costs, which produces a sigmoidal investment function. We also estimate the piecewise linear investment function, which includes as special cases linear models, models with one threshold, the original model of Abel and Eberly, which has two thresholds, and sigmoidal models. Empirical evidence clearly supports the sigmoidal model. The threshold estimate of Tobinfs q is 0.91. The investment ratio does not respond at value of Tobinfs q below 0.91, but begins to react sensitively as Tobinfs q passes 0.91.Tobinfs q, financial constraints, irreversibility of investment, unlisted, Japanese firms, piecewise linear function
"The Myth of the Main Bank: Japan and Comparative Corporate Governance"
Full text linkIn this essay on Masahiko Aoki's recent study of Japanese corporate governance, we argue that he and others misdescribe Japan on several fundamental dimensions. First, Japanese firms and employees choose neither to arrange implicit life-time employment contracts nor to invest heavily in firm-specific skills. Instead, firms keep employees employed during economic downturns only because interventionist courts do not let them lay their employees off. Second, Japanese firms do not organize themselves into keiretsu corporate groups, do not exchange shares with other alleged group members, and do not necessarily use the money-center bank attributed to the group as their "main bank." Last, Japanese "main banks" neither agree in advance to rescue troubled debtors nor monitor firms on behalf of other creditors.
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Farmers and Capitalism
Full text linkMost analyses of modern capitalism focus on bargains struck between workers, managers, and owners (and the different types of firms they inhabit). But considering the substantial influence of institutional inertia on modern outcomes, it is necessary to examine the origins, and to consider which actors were most important in the early construction of capitalist systems. In this regard, farmers have played a critical role. I examine four cases - early 19th Century United States, early 20th Century United States, post-WWII France, and post-WWII Japan - to assess farmers’ influence on the origins of contemporary institutions, and find that they have played an important, though frequently overlooked, role.political economy; capitalism; financial institutions; economic development
Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
