Stata do-files for "Long-Term Care across Europe and the U.S.: The Role of Informal and Formal Care"
The paper estimates the contribution of informal care to total hours of long-term care to elderly people in several European countries and the U.S. It develops a methodology to correct care hours for selection into nursing homes. It also provides a set of stylized facts on how care is provided in the considered set of countries
Codes for "Blast from the Past: The Altruism Model is Richer than you Think"
The paper characterizes the first full characterization of a two-period altruism model without commitment. The codes provided in this dataset enable the user to calculate equilibria under any parameter configuration, plus some more general altruism models. The package also plots illustrating graphs
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Experience vs. Obsolescence: A Vintage-Human-Capital Model
I combine an infinite-horizon version of Ben-Porath’s (1967) model of human-capital accumulation with a vintage structure as in Chari & Hopenhayn (1991). Different skill levelsinside a vintage are complementary in production. Vintage-specific human capital is accumulated based on workers’ optimal strategies and is lost when the technology is phased out by an endogenous firm decision. I establish equivalence between competitive equilibrium and a planner’s problem. It is shown
that returns to skill are highest in young vintages. Accelerated technological change shortens the life cycle of a technology and speeds up obsolescence; the premium on tenure rises because more workers are concentrated in young technologies with high skill premia. A calibration exercise comparing two steady states shows that the model quantitatively accounts for the changes in the experience premium, earnings dispersion and earnings turbulence in German data
Variations on the Author
“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
We 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
Vintage human capital and learning curves
I study a vintage-human-capital model in which long-lived workers accumulate human capital following an exogenous learning curve. Different skill levels inside a vintage are complementary in production; this makes the ex ante homogeneous workers enter different vintages. The continuous-time framework allows me to study the timing decision for the technology phase-out differentially and to derive sharp characterization for wages and the distribution of workers in the dying technology. I show how to posit and solve a planner's problem and construct equilibrium in this way. Consistent with empirical evidence, I show that the experience premium is always positive but diminishes as a technology ages. The connection between workers, learning curves and the technology's progress curve is characterized
