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
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
Empirical Assessment of the Existence of Taxable Agglomeration Rents
Full text linkThe New Economic Geography literature claims that firms are ready to pay more tax in "big markets" because of agglomeration rents. Tax authorities can thus set higher tax rates in denser economic area, hence an opposite mechanism to the "race to the bottom" process described by the classical tax competition theory. The aim of this paper is to empirically assess the existence of such agglomeration rents. We use Swiss data on municipalities corporate income tax rates and firms location to test the tax gap between these municipalities and the most peripheral one using a theory-based relation. Our estimations indicate that municipalities with higher agglomeration rents (measured as the number of firms plus the "potential of neighboring firms") are setting higher corporate income tax rates, hence confirming the existence of taxable agglomeration rents.agglomeration rents; tax competition; potential of neighboring firms
Evaluating the Trade and Welfare Effects of Developing RTAs
Full text linkMany recent papers have pointed to ambiguous trade effects of developing regional trade agreements, calling for a reassessment of their economic merits. We focus on six such agreements currently in force in Sub-Saharan Africa, Asia and Latin America, estimating their impacts on trade flows and welfare. We combine a gravity model with kernel and bootstrap estimation techniques so as to capture the non-monotonic trade effects while imposing minimal structure. Instead of the usual dummy variables for RTAs, we propose a new variable, capturing the number of years of a country's RTA membership, and we adapt the framework proposed by Winters (1997) to relate trade effects to their welfare implications. The results indicate that only AFTA and MERCOSUR have induced positive trade and welfare effects. The remaining RTAs have produced mixed effects for their members.regional trade agreement; kernel regression; bootstrap; welfare
Regional Integration and the Persistent Uneven Spread of Economic Activities in Developing Areas
No full textOne of the striking features of many developing Regional Integration Areas (RIAs) is the strong asymmetry between countries. In this paper, we consider a three-country two-sector model in a footloose capital framework. Two of these countries are involved in a regional integration process while the third is left out of the union. They are “port-like” economies where only one region is endowed with international infrastructures, so that imports and exports between trading partners necessarily pass through this transit region. The comparative statics of our model show that better domestic transport infrastructure helps to attract a higher share of footloose activity when trade costs within the RIA are lowered, inducing a persistent uneven spread of the mobile sector between the member countries. If the domestic infrastructure levels of these countries are both raised towards a high-quality level, a convergence process is triggered to the disadvantage of the country left outside the RIA.Uneven development; regional integration area; transport infrastructure; convergence; developing countries; models
