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
Measuring the Underground Economy with the Currency Demand Approach. A Reinterpretation of the methodology
No full textWe contribute to the debate on how to assess the size of the underground (or shadow) economy by proposing a reinterpretation of the traditional Currency Demand Approach (CDA) à la Tanzi. In particular, we introduce three main innovations. First, we take a direct measure of the value of cash transactions—the flow of cash withdrawn from bank accounts relative to total non-cash payments—as the dependent variable in the money demand equation. This allows us to avoid unrealistic assumptions on the velocity of money and the absence of any irregular transaction in a given year, overcoming two severe critiques to the traditional CDA. Second, in place of the tax burden level, usually intended as the main motivation for non-compliance, we include among the covariates two direct indicators of detected tax evasion. Finally, we control also for the role of illegal production considering crimes like drug dealing and prostitution, which—jointly with the shadow economy—contributes to the larger aggregate of the non-observed economy and represents a significant component of total cash payments. We propose then an application of this “modified CDA” to a panel of 91 Italian provinces for the years 2005–08
L'economia non osservata fra evasione e crimine: una rivisitazione del Currency Demand Approach con una applicazione al contesto italiano
No full textThis study contributes to the debate on estimating the size of
underground economy, by proposing a reinterpretation of the
Currency Demand Approach (CDA). Three main innovations
are introduced. First, a direct measure of cash transactions
is taken as dependent variable in the money demand
equation. Second, indicators of detected tax evasion substitute
difficult-to-find proxies for all the relevant determinants of
noncompliance. Third, a control for cash used in criminal
activities is introduced. The application of this ‘modified-
CDA’ to Italian provinces reveals that the provinces in Centre-
North exhibit a higher incidence on GDP of both the
underground economy and illegal production
Measuring the underground economy with the currency demand approach: a reinterpretation of the methodology, with an application to Italy
No full textWe contribute to the debate on how to assess the size of the underground or shadow economy with a reinterpretation of the traditional Currency Demand Approach (CDA) à la Tanzi. We introduce three main innovations. First, we take as dependent variable in the money demand equation a direct measure of the value of cash transactions: the flow of cash withdrawn from current accounts relative to total non-cash payments. This avoids use of the Fisher equation and so overcomes two severe criticisms of the traditional CDA. Second, instead of the tax burden, usually taken as the main motive for non-compliance, we include among the covariates two direct indicators of detected tax evasion. Finally, we also control for the role of illegal economic activity, such as drug dealing and prostitution, which – jointly with the shadow economy – contributes to the larger aggregate of the unobserved economy and represents a significant component of total cash payments. We then propose an application of this “modified CDA” to a panel of 91 Italian provinces for the years 2005-2008
Money Laundering as a Financial Sector Crime. A New Approach to Measurement, with an Application to Italy
Full text linkAnti–money laundering regulations have been centred on the “Know-Your-Customer” rule so far, overlooking the fact that criminal proceedings that need to be laundered are usually represented by
cash. This is the first study which tries to provide an answer to the question of how much of cash deposited via an official financial institution can be traced back to criminal activities. The paper
develops a new approach to measure money laundering and then proposes an application to Italy, a country where cash is still widely used in transactions and criminal activities generate significant
proceeds. In particular, we define a model of cash in-flows on current accounts and proxy money laundering with two indicators for the diffusion of criminal activities related to both illegal trafficking
and extortion, controlling also for structural (legal) motivations to deposit cash, as well as the need to conceal proceeds from tax evasion. Using a panel of 91 Italian provinces observed over the period 2005-2008, we find that the average total size of money laundering is sizable, around 7% of GDP, 3/4 of which is due to illegal trafficking, while 1/4 is attributable to extortions. Furthermore, the incidence of “dirty money” coming from illegal trafficking is higher in the Centre-North than in the South, while the inverse is true for money laundering coming from extortion
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
