Life Insurance Investment and Stock Market Participation in Europe
No full textIn most European countries life insurance has played a key role in household portfolios, to the extent that it has often been the first asset ever purchased. In this paper we use life history data from a host of European countries to investigate the role of life insurance investment in shaping individuals’ attitudes towards participation in stocks and mutual funds. We show that individuals who purchased a life insurance policy are more likely to invest in stocks and mutual funds later. On the one hand, these findings support the notion that life insurance policies play an educational role in financial investment. On the other hand, they are also consistent with behavioural models where economic agents are first concerned with avoiding unacceptable adverse scenarios by purchasing low risk investments, such as life insurance policies, and then invest in riskier assets, such as stocks and mutual funds, to obtain higher economic returns
Working life histories from SHARELIFE: a retrospective panel
Full text linkThis paper describes in detail the construction of the panel dataset spanning the entire working life of SHARELIFE respondents, discussing all the relevant assumptions needed to reshape the public release data into such a format. We then discuss how new research venues could stem from such a dataset and what distinguishes retrospective panel data from standard panel data
Health and Labor Supply Dynamics of Older Married Workers
No full textThis empirical analysis investigates how the labor supply dynamics of married workers aged 46-65 is influenced by their own health conditions and by those of their cohabiting partners. Exploiting the information conveyed by the European Community Household Panel (1995-2001), our econometric specifications focus on the transition towards not employment within the next year and use alternative health indicators to describe the overall physical and mental conditions of couple members. We also control for partners labor supply because of its close relationship with their own health and the well-documented coordination with the labor market position of the other couple member. Our results show that while healthier individuals present higher chances of remaining at work in the future, living with healthier spouses affects positively the likelihood of ceasing from work. Finally, when the spouse is employed, the probability of keeping on working is estimated to rise. This last result upholds the hypothesis, suggested by the literature, that couple members prefer to spend their time in the same employment status.Labor supply, health, married workers
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
Estimating the Labor Supply Dynamics of Older Workers Using Repeated Cross-sections
No full textThe empirical analysis in this paper adopts logit models to study the hazard rate of ceasing from work by the next year for Italian older employees. The specifications are estimated resorting to the framework proposed by Guell and Hu (2006), which extracts information from repeated independent cross-sections to recover the hazard rate of interest at the individual level. The sample is drawn from the ISTAT survey Aspects of Everyday Life and includes employees aged 50-65 in 1993-2002. Our results show that, even conditioning on a wide set of socioeconomic factors, the age profile of the hazard rate is increasing and confirms the low labor market attachment of older workers. Further, the time evolution of the risk of becoming not employed appears to be hump-shaped and achieves its maximum for the cohorts of employees at work in the period 1996-1998, which is characterized by the introduction of important changes in the Social Security system aimed at extending the working life of the elderly.Labor supply dynamics, duration analysis, generalized method of moments
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
