Public goods, redistribution, and growth: a classical model
No full textAbstract We extend the basic Classical growth model by introducing a productive and redistributive role for the public sector in an economy populated by two classes, workers (who supply labor, consume, and do not save) and capitalists (who own capital stock, consume and save). The government levies a tax on profits in order to: (i) finance the provision of a public good that augments the production possibilities of the economy, and (ii) integrate labor incomes through a transfer to workers. Following Michl (2009), we focus on two different model `closures', which deliver an endogenous and an exogenous growth rate respectively. In both cases, the analysis of taxation and government spending composition between public goods and transfers requires to specify the government's preferences. In the endogenous growth model, the government's choice fixes long-run growth and income distribution. In the exogenous growth model, policy decisions determine income distribution and the employment rate
Endogenous Technical Change, Employment and Distribution in the Goodwin Model
Full text linkThe Goodwin (1967) model of the growth cycle assigns distributional conflict a central role in the dynamics of capital accumulation, but is silent on the determinants of technical change. Following Shah and Desai (1981), previous studies focused on the effects of the direction, or bias of technical change on the growth cycle (van der Ploeg, 1987; Foley, 2003; Julius, 2005). Either implicitly or explicitly, these contributions adopted the induced innovation hypothesis by Kennedy (1964): there exists an innovation possibility frontier out of which profit-maximizing firms freely choose the optimal combination of capital- and labor-augmenting technical change, without having to allocate resources to R&D. Our focus is instead on the choice of intensity of technical change, that is the share of R&D expenditure in output. In our framework, innovation is a costly, forward-looking process financed out of profits, and pursued by owners of capital stock (capitalists) in order to foster labor productivity and save on labor requirements. Our main findings are: (i) similarly to the literature on the direction of technical change, an endogenous intensity of R&D ultimately dampens the distributive cycle; however, (ii) steady state per capita growth, income distribution and employment rate are endogenous, and depend on the capitalists' discount rate, the institutional variables regulating the labor market, and the size of subsidies to R&D activity. Implementing the model numerically, we show that: (iii) a reduction in the capitalists' discount rate lowers per-capita growth, the employment rate and the labor share; (iv) an increase in workers' bargaining power raises the labor share, while reducing employment and per-capita growth; (v) a balanced budget increase in the R&D subsidy also fosters per-capita growth, at the expenses of the labor share. The variations corresponding to (iv) and (v), however, can be small
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
