Cross-over, thresholds, and interactions between science and technology : lessons for less-developed countries.
(2003) Bernardes, Américo Tristão; Albuquerque, Eduardo da Motta e
Presently, science is an important precondition for the economic development of less-developed countries. This paper discusses the specific roles that science has at initial stages of development, pointing to its contributions for the countries’ absorptive capability. Furthermore, this paper specifies the role of science for initiating a positive interaction with technological development, since initial stages of development and during catching up processes. For less-developed countries, neither the linear model of technology nor an “inverted linear model” would take place: a more interactive approach is necessary for development. Using statistics of patents (USPTO) and scientific papers (ISI) for 120 countries (1974, 1982, 1990, and 1998), this paper analyses some evidences on thresholds levels of scientific production to originate an interactive relationship between science and technology. These data also document that the value of this threshold seems to double from one period to another. Although this paper presents tentative results, some policy implications are discussed: scientific institutional building must be seen as a component of modern industrial policies.
A methodology for unveiling global innovation networks : patent citations as clues to cross border knowledge flows.
(2014) Ribeiro, Leonardo Costa; Kruss, Glenda; Britto, Gustavo; Bernardes, Américo Tristão; Albuquerque, Eduardo da Motta e
This paper presents a new methodology to describe global innovations networks. Using 167,315 USPTO patents granted in 2009 and the papers they cited, this methodology shows ‘‘scientific footprints of technology’’ that cross national boundaries, and how multinational enterprises interact globally with universities and other firms. The data and the map of these flows provide insights to support a tentative taxonomy of global innovation networks.
Modeling economic growth fuelled by science and technology.
(2010) Ribeiro, Leonardo Costa; Bernardes, Américo Tristão; Ruiz, Ricardo Machado; Albuquerque, Eduardo da Motta e
Este artigo propõe um modelo de simulação para investigar a contribuição da ciência e da tecnologia para o crescimento econômico. O ponto de partida são os sistemas nacionais de inovação, um conceito que sintetiza a capacitação tecnológica das nações. Desta forma, o modelo pode preservar simplicidade e parcimônia. Os dados coletados (patentes, artigos e PIB e população, para 183 países) indicam uma forte correlação entre ciência, tecnologia e renda. Três exercícios com simulações são realizados para diversos momentos do tempo, mostrando a progressiva aderência do modelo a essas variáveis tecnológicas.
National system of innovation and technological differentiation : a multi- country evolutionary model (preliminary version).
(2005) Bernardes, Américo Tristão; Ruiz, Ricardo Machado; Ribeiro, Leonardo Costa; Albuquerque, Eduardo da Motta e
The paper introduces an agent-based model in which the national system of innovation (NSI) is a main determinant of the wealth of nations. The model is defined as a self-organizing economy where agents are countries with thei r own capabilities for imitation and innovation. The interactions among countries are given by the relative competitiveness of a country in world economy, which is represented by functions that connect their prices, demands, technologies, and incomes. The simulations show that the model reproduces countries hierarchies that have been found in several empirical studies.
Notes on a crisis : the Exzerpthefte and Marx’s method of research and composition.
(2013) Paula, João Antônio de; Cerqueira, Hugo Eduardo Araujo da Gama; Cunha, Alexandre Mendes; Suprinyak, Carlos Eduardo; Albuquerque, Eduardo da Motta e
This paper presents Notebook B113, one of Marx’s unpublished manuscripts, and suggests its importance for highlighting the monetary and financial issues which Marx was investigating after 1867. The contents of this notebook reveal a systematic effort to investigate new features of financial markets and institutions which were spreading throughout Europe during the 1860’s, and which were put in sharp evidence by the events that surrounded the Overend, Gurney crisis in England, in 1866. Besides offering valuable clues with respect to Marx’s method of investigation and composition, the relevance of the themes comprised in the notebook for the analysis developed in part five of Capital’s volume III suggests that these manuscript excerpts and notes were part of the preparatory material for a future revision of that book, which Marx was never able to carry through.
The diffusion of technological knowledge through interlaced networks.
(2011) Ribeiro, Leonardo Costa; Ruiz, Ricardo Machado; Albuquerque, Eduardo da Motta e; Bernardes, Américo Tristão
The diffusion of technological knowledge through interlaced networks In the last decade, many papers discussed the basic features of the networks formed by knowledge diffusion. In this paper, we show that a network formed by the spreading of technological information, represented by the patents citation network, does not obey the expected power law behavior and, therefore, is not a scale-free network. We mapped a network formed by almost 600000 patents, covering a 40 years period. Although the complete network is not scale-free, small portions within the whole network can be described by power laws. The network combines several fields of knowledge, but those power law portions belong to specific fields of technological knowledge. A mathematical model is introduced, which can explain the basic dynamics of the formation of this network.
