To fake or not to fake: An empirical investigation on the fine art market
Full text linkAlthough carefully debated in the legal, aesthetic, and philosophical perspectives, the impact of fakes on the art market has been often overlooked by the economic literature. This paper offers a novel perspective on this issue by investigating the effects of the detection of several Alberto Giacometti’s forged sculptures. Using this exceptional quasi-experiment, the aim of the paper is to analyze whether a specific fake detection persistently influences the prices of a market segment or only exerts a short run effect. The Interrupted Time Series Analysis is adopted to evaluate the impact of fakes across percentiles of the return distribution, accounting for the overall trend in sculpture sales over the period 2000–2015. The empirical evidence shows that in the short run different dynamics emerge across percentiles, but in the medium run fake effects on returns are neutralized
Capitale umano e indici di lettura al tempo della crisi
No full textIl saggio analizza il legame tra indici di lettura e tasso di crescita della produttività del lavoro nelle regioni italiane, utilizzando una pluralità di tecniche econometriche. Nel periodo analizzato, 1995-2016, si evidenzia un indebolimento del legame tra le grandezze in questione, legato alle modifiche delle abitudini di lettura e conoscenza (meno legata al tradizionale supporto cartaceo), alle conseguenze delle crisi economiche che hanno segnato il sistema economico nazionale e alle diverse, se non divergenti, traiettorie socio-economiche delle regioni italiane
The drowned and the saved: the determinants of success in the Italian temporary art and cultural exhibitions market
No full textThis paper develops an empirical analysis of the determinants of the length of temporary art and cultural exhibitions. Using a sample of 659 exhibitions that took place in Italy in the period 2001–2010, a generalized linear model with a logit link and the binomial family was estimated. We also focus on the subsample of prolonged exhibitions, using a logistic accelerated failure time model. The empirical evidence supports the relevance of the subject, location and timing of the exhibition on duration; however, differences in the estimated impact of explanatory variables seem to suggest alternative marketing strategies for prolonged exhibitions
Assessing visitor satisfaction with tourism rejuvenation policies: the case of Rimini, Italy
No full textThis paper assesses the appeal of potential interventions on the tourism offer of Rimini, a popular Italian seaside holiday destination, by means of a choice modelling analysis. Tourism can be viewed as a composite good, its overall utility depending on the arrangement of the component characteristics. The discrete choice experiments here incorporate as attributes a number of possible changes to current tourist activities (the subject of public debate), including them in hypothetical alternative holiday packages. The conditional logit analysis indicates that tourists show lesser preference for interventions aimed at protecting the environmental integrity of the beach and greater preference for those, such as the creation of a pedestrianised seafront with late-night opening of amenities and facilities, that are likely to diminish the role of the traditional sea, sun and sand component of the overall holiday experience.tourism demand, stated preferences, urban planning, decision making, choice experiments,
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
Good students, avid readers: The cost of academic success
Full text linkThe effects of reading habits on academic performances have been carefully investigated, but little is known about the effects of academic achievements on students' leisure reading. This paper investigates this issue by estimating the effects of academic achievements, proxied by the number of exams passed, on leisure reading, measured by the number of leisure books read in a year. Using an online survey submitted to the students at the University of Bologna, Italy, we adopt a two-step control-function technique to control for endogeneity. The empirical evidence suggests the existence of a negative relationship between students' academic achievements and the time devoted to leisure reading. This result holds for students of different fields of study and is stronger for male students. The Blinder-Oaxaca decomposition supports the existence of a gender-specific idiosyncratic effect
