Evaluating the impact of energy poverty in a multidimensional setting
Full text linkWe study the relationship between energy poverty and subjective well-being by combining objective and subjective indicators in a multidimensional energy poverty index (MEPI). Using the Italian release of the European Survey on Income and Living Conditions, we first assess the identification power of this index vis-àvis standard ’affordability’ indicators. Subsequently, we use the MEPI in a simultaneous bivariate ordered probit model accounting for the endogeneity between subjective well-being and energy poverty arising from considering subjective indicators. We find a clear additional role by the subjective indicator in the identification of the energy-poor and a relatively low overlapping degree between MEPI and affordability measures. Likewise, econometric estimations detect sizeable and statistically significant negative effects on life satisfaction as the severity level of the MEPI rises. In contrast, virtually no effects are found with affordability indicators. The impact is substantially smaller when the MEPI only considers the subset of objective indicators
Mental health, lifestyle and retirement
No full textThis chapter presents a mediation model that aims to disentangle the indirect from the direct effects of retirement on health, considering the mediating role of lifestyles. The model is applied to the risk of depression, and physical inactivity is assumed to potentially mediate the effect of retirement. The results indicate that there is a significant indirect effect via the mediator, albeit relatively small in comparison to the direct effect. The analysis highlights the importance of further exploring the influence of lifestyle factors in the relationship between retirement and health, in order to gain a better understanding of the potential pathways through which retirement impacts health
I servizi pubblici
No full textIl 26° Rapporto sull’Economia della Sardegna va in stampa in un momento in cui i segnali sulla salute dell’economia mondiale e nazionale sono incerti e le previsioni di crescita sono riviste al ribasso. Mentre la crescita del 2018 del PIL mondiale si attesta al 3,6%, le proiezioni dei maggiori analisti per l’anno in corso prevedono un rallentamento al 3,3%. In questo contesto, l’Italia appare maggiormente in difficoltà: i dati sui primi mesi del 2019 non sono incoraggianti per il nostro Paese. L’Italia ha rallentato la propria attività economica a causa delle sue carenze strutturali e della bassa produttività del lavoro. Le stime di crescita più ottimiste per il 2019 sono dello 0,1% ma sarà necessario intervenire con politiche economiche mirate a contrastare la recente frenata della produzione industriale
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
Essays on Applied Welfare Economics
Full text linkThis thesis presents three chapters in applied welfare economics. What links all of them is that they point towards the individuals' well-being under different perspectives, and offer insights on potentially vulnerable groups of individuals that experience welfare losses and need improvement in policies to support them. The first and the second chapters provide a complementary analysis of the retirement role on individual well-being, which is observed firstly as individual subjective health status, and secondly, as subjective well-being, namely as an indicator of life satisfaction and an indicator of quality of life. The third chapter aims at analysing the association of energy poverty on the individuals' well-being, clearly it differs to the first two chapters in focus, methods and policy implications. The vulnerable groups we consider are energy poor and retirees. Energy poor are increasing in European countries and one of the main challenges is to be able to target them, given the multidimensional composition of the phenomenon. The growth of the elderly share in the population is an undeniable objective fact that brings out some concerns. In fact, it contribute to add financial burden to welfare states and worries to policymakers who aim at improving the financial stability of healthcare systems while preserving both the welfare and the well-being of older workers and retirees.
The first chapter deals with the retirement impact on general, mental, and cognitive health. Retirement may worsen the individuals' health status when they experience, for instance, a reduction in intellectual or physical daily activities. At the same time, retirement might discourage investment in health by inducing negatively changes in health-related behaviours. Thus, it may affect health status by a direct effect, and by an indirect effect running through health-related behaviours. By using longitudinal SHARE data, and exploiting the mediation analysis in an instrumental variable framework, we built on a model for health and retirement to unpack this causal chain. We also model retirement as a two-stage process, namely, we consider both the status of being retired and the time spent into retirement.
In the second chapter, we turn the attention to a broader definition of individual well-being, and we focus on the impact of retirement on life satisfaction and quality of life. The individual well-being consists of several domains, which people are able to separately or overall evaluate. As an example, exiting the labour market may be beneficial for well-being due to the increase in leisure time, but at the same time, it can be detrimental because of the drop in health status. Thus, retirement may impact subjective well-being in both a positive or negative way, and it is likely that the transition into retirement might adjust in time. By using longitudinal SHARE data, we model the relationship of retirement and well-being in an instrumental variable framework, which accounts for potential endogeneity arising for reverse causality of retirement and subjective well-being, and unobserved individual heterogeneity.
In the third chapter, we investigate the relationship between energy poverty and life satisfaction. After constructing a multidimensional energy poverty index exploiting both subjective and objective indicators, we evaluate its effect on subjective well-being by using ITSILC cross-sectional data. By taking into account the ordinal nature of our variables of interest, we employ a bivariate order probit, to estimate the effect of energy poverty on well-being, and to investigate whether the welfare losses change for any severity level and life satisfaction. As both our main variables contain subjective information, we account for the endogeneity by imposing an exclusion restriction on the energy poverty determinants, namely the decades of the dwellings' construction
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
