Risky Asset Ownership Decisions by the Elderly in the UK: Evidence from the Retirement Survey
Full text linkIn this paper we shed more light on the portfolio behaviour of the older part of the UK population over the period 1988-94. We employ data from the Retirement Survey and different econometric specifications in order to model the risky asset ownership decisions over time. The unique nature of the dataset allows us to control for a variety of factors that may be important for the portfolio behaviour of people that are about to or they have recently retired. Our results are indicative for the role of the fixed participation costs and inertial behaviour in risky asset ownership decisions.household portfolios, risky asset ownership decisions, random effects probit, bivariate probit, transition rates
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

Immigrant self-employment: does intermarriage matter?
Full text linkThis paper investigates the effect of a native spouse on the transitions into and out of entrepreneurship of male immigrants in the U.S. We find that those married to a native are less likely to start up a business compared to those married to an immigrant. This finding is robust when the endogeneity of being married to a native is taken into account. We also show that immigrants married to a native are significantly less likely to exit from entrepreneurship compared to their counterparts who are married to an immigrant. Our results point to an interesting asymmetric role of being intermarried in deciding to become an entrepreneur and for survival in entrepreneurship, which is consistent with a network effect. On the one hand, intermarriage reduces the chance of starting up a business possibly because better access to local networks can help transitions into other forms of employment (e.g. paid employment). On the other hand, superior access to local networks through marriage to a native spouse facilitates business survival
I (don't) owe you: Sovereign default and borrowing behavior
No full textUsing microdata from a U.S. household survey, we document that immigrants who lived through a sovereign default episode are 7% less likely to hold debt relative to otherwise similar immigrants who reside in the same U.S. state and come from the same foreign country but who did not experience a default. Conditional on holding debt, consumers in the former group borrow less and service lower debt burdens. The negative effect on borrowing behavior of having experienced a sovereign default increases with family size and declines with education. These findings highlight the role of personal experience in shaping households' financial decisions
