The Political Economy of Managerial Delegation with Unionized Labor Markets
No full textThe separation in large corporations of ownership from management and the presence of unions in labor markets represent two important widely occurring features of modern economies. Moreover, their importance also seems to be related to the degree of imperfect competition in product markets, since there are theoretically and empirically reasons suggesting that imperfections in the labor market are correlated with imperfections in the product market. This chapter provides a review of the recent contributions in the Industrial Organization game-theoretical literature which analyze the interplay between managerial delegation and union wage bargaining in imperfectly competitive markets. In particular, while the earliest strategic delegation literature points out that delegating strategic decisions to managers acts as a commitment device with a view to altering product market competition, in the presence of unionization, managerial delegation contracts can also be used by firms’ owners to commit to an employment policy, which impacts on the wage bargaining process. The role highlighted by the literature of this wage or bargaining effect related to managerial delegation contracts in affecting product and labor market outcomes, structure and institutions is presented and discussed. Notably, by investigating such issues, those works also contribute to the positive political economy literature. This is because, on the one hand, the underlying processes are based on rational choice and strategic behavior by firms and, on the other hand, their concern includes market institutions and change, as well as welfare and policy implications
Concorrenza ed efficienza nel mercato del commercio elettronico
No full textAs the Internet develops into a robust channel for (e)commerce, many experts state that in online markets competition would be stronger, prices would be much lower and so the market seems to approximate the competitive paradigm. Is this view correct? In this paper we review the growing literature on e-commerce and its market structure, and we analyze, in particular, how the typical ex-post intervention of competition policy could be applied in order to increase digital markets efficiency
TRANSITIONS OUT OF UNEMPLOYMENT: THE ROLE OF SOCIAL NETWORKS' TOPOLOGY AND FIRMS' RECRUITMENT STRATEGIES
No full textIn this paper we study the effects of job contact networks on out-of-unemployment transitions. We find that social connections produce sizable increases in upward mobility from unemployment and, caeteris paribus, symmetric network topologies perform better than asymmetric ones. Furthermore, in scale-free networks the probability of transitions out of unemployment increases in the exponent of the power-law degree distribution, but its value is much lower than the one attainable in Poisson random networks. In addition, and most interestingly, these results strongly depends on the different hypotheses on the firms' recruitment strategy
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
