Essays in Public and Urban Economics
No full textThe first chapter of my Thesis deals with the local impact of rationalisation policies (i.e. public spending cuts) in the field of school services. I combine a staggered difference-in-differences (DID) model with an instrumental variable strategy (IV) that exploits institutional thresholds for school closures, demonstrating how drastic cuts in public school services negatively influence demographic and income dynamics at local level. For the second chapter, I gained access to administrative data of the Italian Social Security Institute (INPS) through the highly competitive VisitINPS Programme. Using a two-steps estimation á la Combes et al. (2008) along with a shift-share IV, I show that the uneven growth of knowledge-intensive sectors produces multiplicative effects on the employment of local workers, decreases their probability of migration, and increases house prices more than nominal wages, resulting in a reduction of real wages. Finally, the third chapter uses unique historical data that I personally collected from the Italian Ministry of Interior to look at the extent to which institutional design has influenced the efficacy of a massive regional development programme (Cassa del Mezzogiorno). Specifically, through a DID model I demonstrate that - in institutionally-fragile settings - the devolution of authority over public investments can generate dynamics of distributive politics, in the form of partisan alignment effects
Knowledge economy, internal migration, and local labour markets
Full text linkThe spatial concentration of knowledge-intensive activities can generate multiplicative effects at the local level. This paper examines how employment growth in knowledge-intensive and tradable sectors affects wage, days worked, and internal migration of non-tradable workers in Italy. We leverage matched employer-employee data (2005–2019) to track individuals across jobs and locations. Our empirical strategy combines a two-step estimation with a shift-share instrument to disentangle the roles of worker sorting and local spillovers. We find that knowledge sector expansion increases the number of days worked locally and attracts non-tradable workers. It also raises nominal wages, but only when sorting is not accounted for, suggesting selective inflows of more productive workers into knowledge hubs. However, rising local living costs offset nominal wage gains, leading to lower real wages
Rational cuts? The local impact of closing undersized schools
Full text linkThe availability of public education services can influence residential choices. Therefore, policies aimed at 'rationalising' service provision by reducing the number of undersized nodes in the public school network can lead to population decline, especially in spatially isolated areas lacking valid alternatives to the removed services. This paper examines the demographic and income effects of primary school closures by exploiting an Italian education reform that resulted in the contraction of the school network. We assess whether school closures impact households' residential choices, over and above preexisting negative population trends that motivate school closures. Our findings indicate that municipalities affected by school closures experience significant reductions in population and income. The effect is primarily driven by peripheral municipalities located far away from economic centers and distant from the next available primary school. This evidence indicates that school 'rationalisation policies', by fostering depopulation of peripheral areas, have an influence on the spatial distribution of households and income, thus affecting territorial disparities
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
