Mandatory rules for sales contracts regarding food and agricultural products in Italy: An assessment of article 62 of Law 27/2012
No full textIl tema delle relazioni commerciali lungo la filiera agroalimentare ha assunto una grande importanza nel dibattito scientifico e politico europeo e nazionale, a causa della recente esacerbazione di due fenomeni con forti ripercussioni sociali ed economiche: la forte fluttuazione dei prezzi delle commodity agricole avvenuta nel biennio 2007-2008, senz’altro attribuibile alla progressiva liberalizzazione del mercato agricolo europeo avvenuta negli ultimi tre lustri (Commissione europea, 2008; Rosa & Vasciaveo, 2010), e l’asimmetrica trasmissione dei prezzi lungo la filiera agroalimentare, che ha contribuito ad aggravare l’erosione del valore aggiunto del settore primario, ad esclusivo vantaggio del comparto distributivo (Ismea, 2012). Di fronte a tali problematiche i policy-maker europei e mondiali hanno ribadito l’importanza dei contratti come strumento di politica agraria volto a garantire una più equa redistribuzione del valore lungo la catena agroalimentare . In questo contesto si è inserito il provvedimento del legislatore italiano, che con l’articolo 62 del d.l. 1/2012 ha inteso dare inizio ad una nuova stagione nelle relazioni contrattuali fra gli attori della filiera agroalimentare, nella speranza di porre freno alla crisi del settore primario italiano. Obiettivo del presente articolo è quello di fornire una prima valutazione sugli effetti prodotti dall’introduzione dell’obbligo dei contratti di cessione dei prodotti agricoli e alimentari, partendo dalle indicazioni della teoria economica, per poi giungere ad una verifica empirica, svolta grazie a nove studi di caso riguardanti altrettanti imprese agroalimentari. Il lavoro è organizzato in quattro parti. La prima contiene la descrizione dei contenuti del provvedimento oggetto d’indagine e del suo quadro giuridico di riferimento. La seconda affronta da un punto di vista prettamente teorico il tema dei contratti, nonché quello del potere di mercato e delle pratiche anticoncorrenziali nel mercato dei prodotti agricoli ed alimentari. La terza contiene una dettagliata descrizione dei materiali e della metodologia di ricerca adottati per perseguire gli obiettivi del lavoro ed esaurire i quesiti di ricerca. Infine, la quarta parte dedica ampio spazio alla descrizione e all’analisi dei risultati delle indagini empiriche
Le aziende agricole nelle filiere corte
No full textL’indagine effettuata grazie ai dati primari del 6° Censimento dell’agricoltura, forniti dal servizio statistico della Regione Umbria, ha consentito di effettuare dapprima una descrizione precisa e dettagliata delle caratteristiche strutturali, territoriali ed economiche delle aziende agricole umbre che esercitano la vendita diretta e, successivamente, ha permesso di esplorare i canali commerciali dei singoli comparti produttivi al fine di osservare la diffusione del circuito breve.
Il confronto con i dati nazionali e il raffronto con le imprese che pur commercializzando la maggior parte del valore della loro produzione non praticano la vendita diretta ha contribuito, inoltre, a chiarire con maggiore evidenza le peculiarità delle aziende agricole umbre che utilizzano la filiera corta rispetto all’universo imprenditoriale circostante, sia a livello nazionale che regionale

A critical assessment of the implementation of CAP 2014-2020 direct payments in Italy
No full textThe Common Agricultural Policy (CAP) reform of 2014-2020 is characterized by a strong mandate of Member States regarding the 1st Pillar. This paper’s objective is to elucidate the possible impacts of Italian choices on direct payments and their coherence with the specific objectives of the CAP, which was established by the Expert Group on Monitoring and Evaluating the CAP (EGMEC): food security and sustainable food production. Thus, an online survey was disseminated among Italian CAP experts in the spring of 2015. The results from a sample of 25 respondents show that Italian direct payments may positively contribute to viable food production by improving agricultural competitiveness. In addition, the combined effect of general direct payment schemes and Italian choices is to ensure sustainable food provision or, at least, to successfully allow the exploration of this new route in CAP history, which most likely represents future challenge for European agriculture
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
Do direct payments efficiently support incomes of small and large farms?
No full textThis paper assesses how efficiently Common Agricultural Policy direct payments enhance farm incomes by applying a quantile continuous treatment effect model on the Italian Farm Accountancy Data Network sample. Adding to previous analyses, we show that income responses to direct payments are higher in large farms rather than in small farms and lower in farms benefiting from larger levels of support. This suggests that direct payments are not very efficient in supporting incomes of small farms and reducing the disparity existing within the farm population. Furthermore, results suggest that there is scope to reduce the amount of payments provided to highly supported farms
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
