Social motives vs social influence: An experiment on interdependent time preferences
Full text linkWe design an intertemporal Dictator Game to test whether Dictators modify their discounting behavior when their own decision is imposed on their matched Recipients. We run four different treatments to identify the effect of payoffs externalities from those related to information and beliefs. Our descriptive statistics show that Dictators display a marked propensity to account for the intertemporal preferences of Recipients, both in the presence of externalities (social motives) and/or when they know about the decisions of their matched partners (social influence). We also perform a structural estimation exercise to control for heterogeneity in risk attitudes. As for individual behavior, our estimates confirm previous studies in that high risk aversion is associated with low discounting. As for social behavior, we find that social motives outweigh social influence, especially when we restrict our sample to pairs of Dictators and Recipients who satisfy minimal consistency conditions
Social preferences and cognitive reflection: evidence from a dictator game experiment
No full textThis paper provides experimental evidence on the relationship between social preferences and cognitive abilities, which we measure using the Cognitive Reflection Test (CRT). We elicit social preferences by way of 24 dictatorial situations, in which the Dictator's choice sets include (i) standard Dictator games, where increasing the Dictator's payoff yields a loss for the Recipient, (ii) efficient Dictator games, where increasing the Dictator's payoff also increases that the Recipient's; as well as other situations in which (iii) either the Dictator's or (iv) the Recipient's monetary payoff is held constant. We partition our subject pool into three groups: reflective (scoring 2 or more in the CRT), impulsive (opting twice or more for the “intuitive” but wrong answers in the CRT) and the remainder. We find that impulsive Dictators show a marked inequity aversion attitude, especially in standard Dictator Games. By contrast, reflective Dictators show lower distributional concerns, except for the situations in which the Dictators' payoff is held constant. In this case, reflective Dictators give significantly more.Financial support from the Spanish Ministries of Education and Science and Economics and Competitiveness (SEJ 2007-62656, ECO2014-58297-R and ECO2012-34928), MIUR (PRIN 20103S5RN3\_002), Generalitat Valenciana (Research Projects Gruposo3/086 and PROMETEO/2013/037) and Instituto Valenciano de Investigaciones Económicas (IVIE) is gratefully acknowledged
Equity and bargaining power in ultimatum games
Full text linkAbstractThis paper studies the extent to which offers and demands in ultimatum games are consistent with equity theory when there is a joint endowment to be distributed. Using a within-subject design, we also investigate the importance of the bargaining power by comparing the subjects’ behavior in the ultimatum and the no-veto-cost game, which differ in the possible cost of responders rejecting the proposers’ offer. Our findings suggest that proposers are willing to reward responders for their contribution to the joint endowment in any of the two games. As for responders, their behavior is consistent with equity theory only in the no-veto-cost game (in which a rejection is costless for them) when the game is first played. When the no-veto-cost game is played after the ultimatum game, we observe that the responders’ demands usually exceed their contribution to the endowment. Finally, this paper reports evidence that the ultimatum and the no-veto-cost game differ in terms of efficiency and rejection rates
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
