Sraffa, il metodo "marginale" e il cambiamento
No full textSraffa's well known rejection of the notion of marginal utility, and most of all of marginal product, is often thought to rest on a methodological preconception on his part: on an argument, that is, that had nothing to do with his interest and his knowledge of economic reality on the one hand, and of the history of economic thought on the other. Through a perusal of Sraffa's unpublished notes on the subject we argue that there was nothing dogmatic (or strictly 'philosophical', to use A. Sen's phrase) about his rejection . Above all, we find that criticising the 'marginal' method was in fact only one side of Sraffa's rediscovery of a method, such as that pursued by the classical economists, better suited for the understanding of the complexity and the variability of economic phenomena
La crisi dell’Unione Monetaria e le relazioni centro-periferia in Europa
Get PDFGiuseppe Celi, Andrea Ginzburg, Dario Guarascio e Anna Maria Simonazzi presentano un sintesi del loro recente libro “Crisis in the European Monetary Union. A core-periphery perspective” dove propongono una lettura di lungo periodo dei problemi dell’Europa. In particolare, essi danno conto del processo di polarizzazione in atto che vede, da un lato, un ‘centro’ forte (la Germania) e, dall’altro, due ‘periferie’ eterogenee ma dipendenti dal medesimo centro (il Sud e l’Est Europa). Nelle conclusioni gli autori indicano la strada da percorre per rinnovare le politiche europee
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
La teoria del salario monetario di Phillips e la curva di Phillips
No full textLa teoria del salario monetario proposta da Phillips (1958) - di cui la celebre curva non è che un elemento - è stata largamente trascurata nella letteratura. Diversamente dalla successiva spiegazione di Lipsey (1960) in termini di squilibri sul mercato del lavoro, la teoria di Phillips mal si concilia con l’analisi neoclassica essendo piuttosto riconducibile, sia nel contenuto che nel metodo, all’analisi delle variazioni dell’unità-salario di Keynes.
La teoria di Phillips considera i salari monetari soggetti a un complesso sistema di influenze e ritiene essenziali fattori socio-istituzionali: caratteristiche che la rendono utile a interpretare risultati empirici spesso apparentemente contraddittori.(Phillips's theory of money wage and the Phillips curve).
The theory of money wage that Phillips (1958) proposed along with the famous curve has been almost completely neglected by economic literature. Unlike Lipsey's (1960) explanation in terms of disequilibria in the labour market, Phillips's theory is quite extraneous to neoclassical analysis, while being similar - both in method and content - to Keynes's analysis of the variations of the wage-unit.
In Phillips's theory, money wages are subject to a complex system of influences, and social and institutional factors play a relevant role: these features make his theory particularly relevant for interpretation of puzzling empirical evidence
Digital upgrade in the automotive supply chain in Mexico: issues and challenges
Get PDFThe ongoing digital transformation poses diverse challenges to the automotive sector. While the process of digitalisation will lead to technical and organisational changes across and within the global value chains, the ongoing changes in the trade agreements spurred by the Trump administration may change the location advantages of previous plants and their specialisations. In addition, investment in the electric car may offer first-mover advantages in markets, while requiring the re-organisation of the value chains. Mexico, ranked in 2018 as the seventh producer at world level, is an important case study for several reasons: among these, its cost advantages, its privileged access to the US market, that attracted many OEMs from Europe, Asia, the US, and its role in the prospective regionalization of world trade. By using interviews to automotive suppliers, experts and business associations of the automotive industry, the paper aims at providing a first outline on issues to be addressed in an analysis looking at how these changes are affecting opportunities for the OEMs in their value chains based in the Mexican automotive system
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
