Much ado about extremes: An experimental test of the shaping effect of prices on preferences
No full textThere is evidence of a shaping effect of market prices on subjects’ evaluations in repeated private value auctions. This evidence has been traditionally interpreted as a pure behavioural phenomenon in contexts where the only available information is the market price. In this paper, we enrich the subjects’ information set by providing in treatment groups additional information on extreme asks. Our main results show a shaping effect both in the control and in the treatments and a stronger effect of the extreme information that more than halves the effect of the market price on subjects’ asks. Differently from the existing literature, we find that the provision of additional information inactivates the well-documented tendency of the market price to fall at each auction round as a consequence of over-asking correction. We discuss different possible mechanisms underlying this key finding
A Resource Sensitive Framework for Defining and Measuring Equality of Opportunity in Health
No full textWe offer a new framework for defining and measuring disparities in the distribution of health opportunities. These are conceived as inversely related to the cost of a specified bundle of health services of given quality, computed by monetizing all the concrete impediments that must be overcome to get access. In the ex-ante perspective we adopt, what is salient is the distribution of costs across cells, where each cell is defined by a set of characteristics determining access barriers. Differently from the existing health literature, our approach allows to disentangle the opportunities individuals enjoy from the mere utilization of health services, working equally well with monetary as well as real costs of access (formal and effective equality of opportunity), where real costs accounts for socioeconomic conditions. Accordingly, an index for the measurement of equality of health opportunities is proposed and resource-conditional policy suggestions are deducted. Given available resources, the design of egalitarian policies is found to depend on how chances of access and socioeconomic conditions are distributed, as well as on the cost borne by the individual occupying the best-off cell

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
Public subsidies and cooperation in research and development. Evidence from the lab
Full text linkWe implement an experimental design based on a duopoly game in which subjects choose whether to cooperate in Research and Development (R&D) activities. We first conduct six experimental markets that differ in both the levels of knowledge spillovers and the intensity of competition. Consistently with the theory, we find that the probability of cooperation increases in the level of spillovers and decreases in that of market competition. We then replicate the experimental markets by providing subsidies to subjects who cooperate. Subsidies relevantly increase the probability of cooperation in focus markets, causing, however, a sensible reduction of R&D investments. Overall, our evidence suggests that, depending on the characteristics of the market, the use of public subsidies might be redundant, for firms would anyway joined their R&D efforts; or counterproductive, inducing firms to significantly reduce R&D investments compared to the non-cooperative scenario
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
