Virtual vs. Standard Strike: An Experiment
In this paper we compare - in the laboratory - stoppage and virtual strike. Our experiment confirms that higher wages offered by an employer lead to considerably more costly effort provision. The number of strikes, the level of efforts and average total payoffs are higher under virtual strike than under standard strike. However, when standard strike is associated with reciprocal externalities, it induces higher effort levels, higher payoffs and an extremely reduced number of strikes than virtual strike. It is unclear whether this behavior re?ects reciprocity or other forms of social preferences. However our results might explain why standard strikes rather than virtual ones are generally adopted by workers.virtual strike, cooperation, reciprocity, fairness, experiments
Voting by Ballots and Feet in the Laboratory
This paper provides laboratory evidence on the efficiency-enhancing properties of the Tiebout model as a decentralized system of public goods provision. Tiebout (1956) shows that if a sufficient number of local communities exist to accommodate different types of preferences, individuals sort themselves in a way that provides an efficient allocation of public goods and taxes. Our experiment aims to disentangle the effect of voting participation and is composed of two treatments. In the non-participation treatment, local public good provision is chosen by only one subject, while the other members of the community can only stay in or move to another community. In the participation treatment, all the community members have the right to vote as well as to move to another community and collective decisions are taken by majority rule. Our findings show that social welfare is greater in the participation than in the non-participation treatment. We conclude that voting with one’s feet increases efficiency if all the community members vote and that the influence of voting participation on the allocation of local public goods should be taken into account to assess the viability of the Tiebout model.Tiebout model, local public goods, voting participation, federalism, experiment.
Cognitive Biases and Gaze Direction: An Experimental Study
This paper investigates the validity of the model of dual processing by means of eyetracking methods. In this theoretical framework, gaze direction may be a revealing signal of how automatic detection is modified or sustained by controlled search. We performed an experiment by using a stylized decisional framework, i.e. informational cascade, proposed by economists to investigate the rationality of imitative behavior. Our main result is that automatic detection as revealed by gaze direction is driven by mechanisms that are dependent on cognitive biases. In particular, we find significant statistical correlation between subjects’ first fixation and their revealed patterns of choice. Our findings support the hypothesis that the process of automatic detection is not independent on cognitive processes.informational cascades, overconfidence, eye-tracking, information processing, cognitive biases
Outsourcing and Information Management.
This paper compares outsourcing processes in France, Italy and Japan in two types of firms, large firms and also small firms. It is shown that outsourcing has increased over the last two decades in both small and large firms in all three countries and that mainly in the last decade the tendency has been to increasingly involve some of the suppliers in product development. We interpret this evidence by means of a cognitive framework related to the activity of information management. Specifically, we show that the more the relationships among suppliers and users are characterised by two-way communication, decentralised information processing, and accordingly balanced contractual power, the more the incentives to create knowledge and to innovate autonomously are guaranteed.Firm size; Information; Network; Outsourcing

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
