La nueva historia económica, la teoría de la regulación y el análisis histórico social: Notas para un debate

The primary purpose of this essay is to demonstrate whether the new economic history (NEH) is a variant of social history, or if it has an origin in the economy as such. The article demonstrates the latter, which leads it to consider the specific paradigm of its genesis, its strengths and weaknesses and the importance to economic historian and social analysis. Stated above, we outline an alternative perspective that make possible to overcome some of the shortcomings of this paradigm, which has become a dominant methodology for economic history. This renewed look at historical economic phenomena, recovers the social essence that characterized the economic history in its originsEl propósito fundamental de este ensayo es demostrar si la nueva historia económica (NHE) es una variante de la historia social, o si la misma tiene un origen en la economía como tal. El artículo demuestra lo último, lo cual lo conduce a considerar el paradigma específico de su génesis, sus debilidades y fortalezas, y la importancia para el historiador económico y para el análisis social. Planteado lo anterior, se esboza una perspectiva alterna que posibilita superar algunas de las falencias de este paradigma, que se ha constituido en una metodología dominante para hacer historia económica. Esta renovada mirada a los fenómenos histórico económicos, recupera la esencia social que caracterizó en sus orígenes la historia económica

Estructura tecnológica de las exportaciones industriales en América Latina (1990-2010)

We analyze the behavior of industrial exports from a representative sample of Latin American countries in the period 1990-2010, taking into account its technological content and contrasting it with the performance of the United States, the European Union and South Korea equivalent exports. At this time most countries of the region undertook a series of reforms in international trade, which in some cases were further deepened, while in others stagnated or were reversed. The main hypothesis of the paper is that the region presented, at the beginning of the new millennium, a process of exports diversification towards products with greater technology intensity. This process has been overshadowed, with some exceptions (Brazil, Mexico), by the expansion of trade in primary products, which recomposed the export basket in detriment of industrial products, and placed some of these countries in a precarious path of integration into the world economy. The information analyzed supports the validity of this conjecture.Se analiza el comportamiento de las exportaciones industriales de una muestra representativa de países latinoamericanos en el periodo 1990-2010, teniendo en cuenta el contenido tecnológico de las mismas y contrastándola con el desempeño de Estados Unidos, la Unión Europea y Corea del Sur. En este tiempo la mayoría de países de la región se comprometió con una serie de reformas al comercio internacional que en algunos casos se profundizaron y en otros se estancaron o se reversaron. La hipótesis del trabajo es que, en términos generales y relativos, la región presentaba en la entrada del nuevo milenio un incipiente proceso de diversificación exportadora basada en productos con mayor incorporación de tecnología. Este proceso se ha venido opacando, con algunas excepciones (Brasil, México), por la expansión del comercio de productos básicos y mineros, reprimarizando la oferta exportable y colocando a la mayoría de países de la región en una precaria senda de inserción en la economía mundial. La información aquí analizada apoya la validez de dicha conjetura

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
