Tasso nelle Annotazioni leopardiane
No full textNel lavoro di documentazione che Leopardi svolge dal 1822 al 1824 per certificare l'origine letteraria della propria nuova lingua poetica, ha un posto di particolare preminenza la lingua di Tasso, che si rivela un autore particolarmente congeniale al poeta, non solo per ragioni biografiche, ma anche strettamente linguistiche, come mostrano le note autografe apposte sul manoscritto della Annotazioni, la cui edizione critica, procurata da Paola Italia nel 2006, è interpretata e studiata nel contesto critico letterario della formazione del libro delle Canzoni del 1824.In the work of documentation that Leopardi plays from 1822 to 1824 to certify the origin of their new literary poetic language, has a place of special prominence the language of Tasso, the author reveals a particularly congenial to the poet, not only for biographical reasons, strictly linguistic but also, as shown by the notes affixed to the autograph manuscript of the Notes, whose critical edition, procured by Paola Italy in 2006, is interpreted and studied in the context of the formation of the literary critic of the book Songs of 1824
The Size Distribution of Farms and International Productivity Differences
No full textThere is a 34-fold difference in average farm size (land per farm) between rich and poor countries and striking differences in their size distributions. Since labor productivity is much higher in large relative to small farms, we study the determinants of farm-size differences across countries and their impact on agricultural and aggregate productivity. We develop a quantitative model of agriculture and non-agriculture that features a non-degenerate size distribution of farms. We find that measured aggregate factors such as capital, land, and economy-wide productivity cannot account for more than 1/4 of the observed differences in farm size and productivity. We argue that, among the possible explanations, farm-level policies that misallocate resources from large to small farms have the most potential to account for the remaining differences. Such farm-size distortions are prevalent in poor countries. We quantify the effects of two specific policies in developing countries: (a) a land reform that imposes a ceiling on farm size and (b) a progressive land tax. We find that each individual policy generates a reduction of 3 to 7% in average size and productivity.aggregate productivity, agriculture, farm-size distortions, misallocation
Transportation Costs And Economic Development
No full textThis dissertation contributes to a growing literature using microeconomic data to explore questions in macroeconomic development, with particular focus on the importance of transportation costs. Specifically, I study the importance of idiosyncratic transportation costs and economic development via three different angles.
In Chapter 1, I study how idiosyncratic transportation frictions as labor mobility barriers affect the sectoral sorting of workers between agriculture and non-agriculture and quantify their impact on aggregate and sectoral productivity, the pattern of occupational choices and selection. I add idiosyncratic transport costs by sector to an otherwise canonical two sector Roy model. I combine panel data on household level transport costs and income from Honduras with a structural model to quantitatively estimate the impact observed transport costs on the reallocation of labor and aggregate development through this selection channel. When removing transport costs, share of agricultural employment drops by 8 percent, agricultural productivity increases 1.32-fold and real GDP per worker rises 1.19-fold.
In Chapter 2, I examine whether the geographic location of farmers, and their distance from markets can account for measured misallocation in the data. I quantitatively examine this question by leveraging a transport infrastructure development program in El Salvador. I use panel micro-level data on transport costs and agricultural production at the farm level along with a structural model in which farmers produce subject to transportation costs. The key insight of my model is that in the presence of transport costs the implied efficient allocation is different than that in the canonical model of misallocation.
In Chapter 3, I explore the role idiosyncratic transportation costs from farm to market play in contributing to a pronounced subsistence agricultural sector. Particularly, I study how idiosyncratic transportation costs to market affect crop commercialization among farmers in Tanzania in the long rainy season. Methodologically, I combine panel data from the Tanzania National Panel Survey with a structural model to quantitatively examine the role transport costs play in facilitating the transformation from subsistence to commercial farming. I find that reductions in transport costs for food crop farmers, sees switching to cash crop farming
Unsupervised author identification and characterization
No full textAuthor identification is a hot topic, especially in the Internet age. Following our previous work in which we proposed a novel approach to this problem, based on relational representations that take into account the structure of sentences, here we present a tool that computes and visualizes a numerical and graphical characterization of the authors/texts based on several linguistic features. This tool, that extends a previous language analysis tool, is the ideal complement to the author identification technique, that is based on a clustering procedure whose outcomes (i.e., the authors’ models) are not human-readable. Both approaches are unsupervised, which allows them to tackle problems to which other state-of-the-art systems are not applicable

Il «Tasso a Sant’Anna» di Nelo Risi
No full textL’articolo analizza la poesia "Il Tasso a Sant’Anna" di Nelo Risi, pubblicata per la prima volta nella raccolta "Amica mia nemica" (1976) e poi riproposta, con qualche variante, in "I fabbricanti del «bello»" (1983). Incentrata sul periodo della prigionia di Tasso nell’ospedale di Sant’Anna a Ferrara (1579-1586), questa poesia si distingue da altri testi dedicati da poeti italiani del Novecento all’autore della "Gerusalemme liberata" per il massiccio riutilizzo di passi provenienti dall’epistolario tassiano, e precisamente dalle lettere scritte durante la reclusione, che Risi potrebbe aver letto in un’edizione del 1960, curata da F. Costabile. L’analisi del testo si propone anzitutto di individuare i singoli passi tassiani riutilizzati da Risi, interrogandosi anche sul valore che il poeta milanese ha voluto assegnare alla figura di Tasso e alla drammatica esperienza del suo internamento: un’interpretazione alla quale non è estraneo il ricordo di Montaigne e del racconto del suo incontro con Tasso, contenuto nel secondo libro degli "Essais".The article analyses the poem "Il Tasso a Sant’Anna" by Nelo Risi, first published in the collection "Amica mia nemica" (1976) and later republished, with some variations, in "I fabbricanti del «bello»" (1983). Focusing on the period of Tasso’s imprisonment in the hospital of Sant’Anna in Ferrara (1579-1586), this poem differs from other dedicated by 20th-century Italian poets to the author of "Gerusalemme liberata" due to the massive re-use of passages from Tasso’s epistolary, specifically from the letters written during his imprisonment, which Risi may have read in a 1960 edition edited by F. Costabile. The analysis of the text aims first of all to identify the passages reused by Risi, also questioning the value that the Milanese poet wished to assign to the figure of Tasso and to the dramatic experience of his internment: an interpretation to which the memory of Montaigne and the account of his meeting with Tasso, contained in the second book of the "Essais", is not extraneous
