Os Efeitos do Gasto do Governo sobre o Investimento do Setor Privado no Brasil entre 1970 a 2009
Full text linkThis article analyzes whether public administration investments complement or replace (crowding-in or crowding-out effect) private sector investments in Brazil between 1970 and 2009. Using an error correction mechanism model, the results show that investments public administrations have a substitute effect for private investments. The results also show that the growth in demand contributes to private sector investments, confirming the investment accelerator theory for the Brazilian economy in the period under analysis.Este artigo analisa se os investimentos das administrações públicas complementam ou substituem (crowding-in ou crowding-out effect) os investimentos do setor privado no Brasil entre 1970 a 2009. Utilizando um modelo de mecanismo de correção de erros, os resultados mostram que os investimentos das administrações públicas apresentam um efeito substitutivo aos investimentos privados. Os resultados mostram também que o crescimento da demanda contribui com os investimentos do setor privado, confirmando a teoria do acelerador do investimento para a economia brasileira no período em análise
Os determinantes do investimento privado na economia brasileira: 1955-2003
Full text linkEsta dissertação apresenta um teste empírico sobre os determinantes do investimento privado no Brasil entre 1955 e 2003. Inicialmente é realizada a análise teórica da função investimento nas escolas do pensamento neoclássica, keynesiana, marxista e kaleckiana. Num segundo momento, é estudada a trajetória de crescimento da economia brasileira, a qual apresenta duas fases no período em análise. Na primeira, de 1955 ao final da década de 70, houve um rápido crescimento do produto; na segunda, dos anos 80 até 2003, ocorreu uma reduzida expansão da atividade econômica. Por fim, é empregada a metodologia dos vetores auto-regressivos (VAR) para testar a função investimento no país. Os resultados mostram que o investimento privado na economia brasileira é associado positivamente ao investimento público, a lucratividade, e a abertura comercial; por outro lado, ele é negativamente associado à carga tributária, a taxa de inflação e a taxa de juros.This M. A. dissertation presents an empirical test for the determinants of the private investment function in Brazil between 1955 and 2003. Firstly, it is revisited the theoretical analyses of the investment function for the neoclassical, Keynesian, Marxist and Kaleckian school of thought. Secondly, it is analyzed the Brazilian economic growth in the period of study. It presented two phases, from 1955 to 1980 there was a high rate of expansion; from 1980 to 2003 there was reduced economic growth. Lastly, it is employed a vector auto-regressive (VAR) model to test the private investment function in Brazil. The results show that the private investment is positively associated with the public investment, the profit rate, and the opening up of the trade balance and it is negatively correlated with the tributary tax, the inflation rate and the interest rate

Determinantes das exportações do Rio Grande do Sul entre 1997 e 2021
No full textThe present study presents an empirical analysis of the determinants of exports from Rio Grande do Sul between 1997 and 2021. Over the last 25 years, there has been a clear change in both the matrix of exported goods and the destination of exports of goods from RS. Using the Ordinary Least Squares methodology, the results found in the empirical analysis show that the expansion of exports to China contributes to the expansion of exports of primary sector goods. Consequently, this expansion is the determining factor for the decline in manufactured exports.O presente estudo apresenta uma análise empírica dos determinantes das exportações do Rio Grande do Sul entre 1997 e 2021. Nos últimos 25 anos, houve uma clara mudança tanto na matriz de bens exportados quanto no destino das exportações de mercadorias do RS. Utilizando a metodologia de Mínimos Quadrados Ordinários, os resultados encontrados na análise empírica mostram que a expansão das exportações para a China contribui para o aumento das exportações de bens do setor primário. Consequentemente, essa expansão é o fator determinante para a queda das exportações manufaturadas
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
Crescimento econômico através das exportações: um estudo empírico para os países dos BRICS
No full textCom base na teoria de Thirlwall e considerando o aprofundamento das relações comerciais internacionais nas últimas décadas, este estudo buscou identificar quais países integrantes do bloco econômico dos BRICS têm seu crescimento econômico limitado pelo Balanço de Pagamentos. Para tanto, foi conduzida uma análise empírica utilizando a metodologia ARDL (Autoregressive Distributed Lag), abrangendo o período de 1961 a 2023. Os resultados apontam que, entre os países analisados, Rússia e Índia apresentam crescimento econômico restringido pelo comércio internacional
