Linking Economic Complexity, Institutions and Income Inequality

Por • 31 may, 2015 • Category: Economía

The mix of products that a country exports predicts that country’s subsequent pattern of diversification and economic growth. But does this product mix also predict income inequality? Here we combine methods from econometrics, network science, and economic complexity to show that countries that export complex products – products that are exported by a few diversified countries – have lower levels of income inequality – at comparable levels of GDP per capita and education – than countries exporting simpler products. Using multivariate analysis we show that the connection between income inequality and economic complexity is stronger than what can be explained using aggregate measures of income, institutions, export concentration, and human capital, and also, that increases in economic complexity are accompanied by decreases in income inequality over long periods of time. Finally, we use the position of a country in the network of related products – or product space – to explain how changes in a country’s export structure translate into changes in income inequality.

Greeks were right : critical comments on Qbism

Por • 31 may, 2015 • Category: Educacion

In this short essay we reject the interpretation of quantum theory called quantum Bayesianism (Qbism) which has been promoted recently by David Mermin in his essay published in Nature. According to Qbism quantum states are personal judgements of human agents. Physicists are not verifying their personal beliefs about their observations but search for the mathematical abstract description allowing to explain and to predict in a quantitative way the regularities observed (and those to be discovered) in physical phenomena which exist independently of the presence of any agent. We reject also the claim that Qbism explains properly the quantum nonlocality. The distant long range correlations can be correctly explained using a contextual statistical interpretation of quantum theory. We conclude that the Greeks were right to remove a perceiving subject out of Science.

Yet another time about time

Por • 31 may, 2015 • Category: Ciencia y tecnología

This paper presents yet another personal reflection on one the most important concepts in both science and the humanities: time. This elusive notion has been not only bothering philosophers since Plato and Aristotle and goes throughout human history embracing all analytical and creative (anthropocentric) disciplines from mathematics through physical and life sciences to philosophy, psychology, music and art, with a vast body of knowledge across different theories and categories concerning its nature (rational, irrational, arational), appearances/qualia, degrees, dimensions and scales of conceptualization (internal, external, fractal, discrete, continuous, mechanical, quantum, local, global, etc.), duration ranges, resolutions, modes (present, now, past, future), variety of tenses (e.g. present perfect, present progressive, etc.) and some intuitive, but also fancy phenomenological characteristics such as arrow, stream, texture, width, depth, density, even scent and perhaps the most distinct one of them: the absolute time constituting the flow of consciousness according to Husserl, the reflection of pure (human) nature without having the distinction between exo and endo.

What are China’s top economic weaknesses?

Por • 31 may, 2015 • Category: Ambiente

What are China’s vulnerabilities? What are the top economic risks for this huge country that drives global growth and is running ahead of the pack of developing nations?. Recently, Andrew Shenga fellow at Fung Global Institute, wisely noted that China is preparing for a great transformation that will propel the Chinese state out of the shadow of Deng’s reforms and allow it to enter a new dimension. It sounds almost like a sci-fi novel. In fact, it’s possibly the closest thing on earth that combines space and time travel. However, there are some speed bumps in the present Chinese system that have to be resolved before China can embark on this great journey. We shall only dwell briefly here on the reasons for these bumps, as well as possible solutions. The stakes are great in any event. The problems could be so huge that they bog down, stall, and eventually kill Chinese growth. The flip side that solving them could bring a huge new boost to China’s economic performance.

Por una agenda estratégica de América Latina (2/2)

Por • 30 may, 2015 • Category: sociologia

La coyuntura latinoamericana contemporánea, que mostró grandes avances en los proyectos y procesos de integración regional, a partir de un nuevo ciclo de acumulación política de las fuerzas progresistas y de izquierda en la región que se inicia con el siglo XXI, se muestra, hoy en día, como un amplio espacio de disputa entre dos proyectos antagónicos.

El Ego Trascendental como Ego lógico en el materialismo filosófico

Por • 30 may, 2015 • Category: Filosofía

¿Es la idea de Ego Trascendental necesariamente la clase vacía, desde una filosofía materialista? ¿Son las ideas de Ego Trascendental y de materialismo unívocas, o son más bien análogas, teniendo diversas modulaciones incompatibles muchas veces entre sí? ¿Son estas ideas exentas, simples, o requieren del análisis de otras ideas filosóficas fundamentales? Y si es así, ¿cuáles son? ¿Qué papel juega la idea de Ego Trascendental en la Historia de la Filosofía? ¿Qué relación tiene, en el materialismo filosófico, la idea de Ego Trascendental respecto de las ideas de Mundo y de Materia ontológico-general?

From Kantian-Reinen Vernunft to the Real Dark Energy Density of the Cosmos via the Measure Concentration of Convex Geometry in Quasi Banach Spacetime

Por • 30 may, 2015 • Category: Leyes

The paper argues strongly in favour of the opinion that Kantian pure reason could be implemented via pure mathematics to reveal a true deep aspect of the fundamental monads of the real physics of the cosmos. Thus using a remarkable pure mathematical-geometrical result stating that under certain conditions a manifold will have 96 percent of its volume concentrated near to its surface, we conclude that the 96 percent dark energy causing the edge of our universe to expand is a direct consequence of this pure geometrical result.

Iterative forcing and hyperimmunity in reverse mathematics

Por • 30 may, 2015 • Category: Ciencia y tecnología

The separation between two theorems in reverse mathematics is usually done by constructing a Turing ideal satisfying a theorem P and avoiding the solutions to a fixed instance of a theorem Q. Lerman, Solomon and Towsner introduced a forcing technique for iterating a computable non-reducibility in order to separate theorems over omega-models. In this paper, we present a modularized version of their framework in terms of preservation of hyperimmunity and show that it is powerful enough to obtain the same separations results as Wang did with his notion of preservation of definitions.

Newton’s second law: not so elementary (as it may seem)

We propose an interpretation of the Newton’s second law that is suggested by Galilean Relativity theory.
