When do the expectations of others matter? Experimental evidence on distributional justice and guilt aversion
Full text linkDistributional justice—measured by the proportionality between effort exerted and rewards obtained—and guilt aversion—triggered by not fulfilling others’ expectations—are widely acknowledged fundamental sources of pro-social behavior. We design three experiments to study the relevance of these sources of behavior when considered in interaction. In particular, we investigate whether subjects fulfill others’ expectations also when this could produce inequitable allocations that conflict with distributional justice considerations. Our results confirm that both justice considerations and guilt aversion are important drivers of pro-social behavior, with the former having an overall stronger impact than the latter. Expectations of others are less relevant in environments more likely to nurture equitable outcomes
Does procedural fairness crowd out other-regarding concerns? A bidding experiment
No full textBidding rules that guarantee procedural fairness may induce more equilibrium bidding and moderate other-regarding concerns. Here, we investigate procedural fairness in the sense of Gueth 2011. In our experiment, we assume commonly known true values and only two bidders to implement a best-case scenario for other-regarding concerns. The two-by-two factorial design varies ownership of the single indivisible commodity (an outside seller versus collective ownership) and the price rule (first versus second price). Our results indicate more equilibrium behavior under the procedurally fairer price rule, although this does not completely crowd out other-regarding concerns. In addition, the limits of procedural fairness turn out to be much more important than expected
An esplorative study of skills and openness in Open Source Software projects
No full textThis paper is about Open-Source Software projects and individual contributors. We aim to show the association between skill profiles and roles assigned to different contributors. Moreover, our analysis focuses on the implications for project performance of members’ skill heterogeneity and the share of external contributors, as a measure of the project’s embeddedness. Our empirical analysis draws on a large sample of Open Source Software projects. For each project we have information about individual contributors such as skills and roles assigned. Key variables at the project level are the number of core members and peripheral contributors, the level of skills, the number of intended audiences (e.g., developers and end-users), and various measures of activity (e.g., number of file releases and bugs closed). We conduct a multinomial logit analysis to predict the role played by individual contributors (e.g., developers and project managers). We also estimate the contribution of skills and openness to projects’ survival and activity
The right person for the right job: workers’ prosociality as a screening device
Full text linkThe impact of workers’ non-pecuniary motivation on their productivity is a fundamental issue in labor economics. Previous studies indicate that prosocially motivated workers may perform better when assigned to jobs having socially desirable implications – even if effort is non-contractible and they are offered a low-powered fixed-compensation scheme – as compared to a standard job with an effort-contingent payment. This suggests that profit-maximizing employers should assign workers to different jobs, based on workers’ prosociality. We run an experiment to explore the link between workers’ prosociality and their level of effort under a prosocial and a standard job. Our experimental results provide some support to the hypothesis that selfish employers exploit the information on workers’ prosociality to assign them the type of job that would be most profitable from the firm’s perspective. However, the prosocial motivation of employers emerges as a second important determinant of their contract choice: employers’ prosociality drives their contract choice, when the worker is not prosocial
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
