What is the nature and causes of the wealth of nations? It was the question that gave rise to economic science in the eighteenth century, and that inaugurated a school of economic thought known as “the classics”, whose most well-known representative, to be considered precisely the father of the economy, was Adam Smith . The answer given by these thinkers was that the source of wealth and engine of economic growth of nations, was determined by the accumulation of resources (land, labor and capital) by nature scarce, by population growth (long term limited by the own availability of resources), as well as by the productive specialization as strategy of optimization in the use of the same ones and of the market like allocating mechanism of the resources in the economy .Under these premises, it was evident that in the long term, once the resources of society were fully utilized, what was called “the steady state” would be reached, that is, a moment in time from which it would be impossible to continue growing . Under this framework of analysis it is understandable the relevance given by the classics to international trade, because it constitutes an escape valve to the “steady state” by making available unused resources (for example land for cultivation) and markets for surpluses productive .Basically, they dominate in them the idea that growth has limits, due to the avai-lability of resources, by nature, finite . Three aspects stand out in the notion of growth elaborated by this school of economic thought:• Accepting that growth depended fundamentally on available resources, which are scarce by nature .• Consequently, they recognized that growth necessarily had limits .• The importance accorded to the accumulation of capital and the long-term eco-nomic dynamics .In a second phase, in the evolution of the notion of growth, we try to break with the idea that growth has limits, by adding, as a determinant of it, to technological pro-gress . From the work carried out by Solow (1956) since the mid-twentieth century, it is accepted that the productive application of science and technology allow breaking the “straitjacket” that means the limitation of productive factors, which lead to the stationary state . Solow concludes that economic growth is something more than the sum of the marginal contributions of productive factors to find what was later called in the economic literature, the “residue of Solow .” That is, an added value that was not explained by the quantitative contribution of the productive factors at stake and that he credited to the technological progress applied to the productive process .From this moment it was thought that technological progress would break with any barrier (natural or technical) that would obstruct the growth of the economy, ma-king this a process of unlimited expansion .

The Asian investment has had an important presence in productive sectors considered motors of the Mexican economy, and the automotive and auto parts industry is one of them . Its economic dynamism has grown especially since the entry into force of the North American Free Trade Agreement (nafTa), in 1994 . Since the 1980s, the economic policy of Mexico had among its objectives the growth of International Trade . In addition, it is considered that foreign direct investment (fdi) is extremely important for the creation of jobs; and although there have been few advances in this aspect; the expectation of creating productive linkages with the Mexican industry persists . Although, according to macroeconomic statistics, progress has been made thanks to this public policy, the truth is that only significant impacts of its location are observed at the regional level .The automotive companies of Asian capital are an essential part of the geographical configuration of the automotive and auto parts industry around the Bajío region, which is considered a very important corridor for it . For this reason, the present work focuses on identifying its size, structure and dynamism in this region since the entry into force of nafTa . Regional economic indicators and the causes that have contributed to the growth of Asian investment in the automotive sector are analyzed .

The industrial structure was one of the fundamental elements of the conditions for the development of social struggles in the city of León, Guanajuato, in the second half of the 20th century . The study of the existing industrial structure and, particularly, the predominant branch of production in this city since the forties, is the production of footwear . The developed concrete figure reached in it is the factory system, which determines the whole of Leon’s industrial production . This manufacturing system showed a qualitative division and the quantitative proportionality of the machinery system, which nevertheless presents imperfections in its development that are expressed in the peculiarities of that industrial structure .

The objective of this paper is come up with proposals that help to understand the risks that mining companies must consider in order to reduce the negative impacts that they currently cause, since apart from the effects that are not con-sidered during the operation of the project, they generally do not carry out an appropriate closure at the end of the project . As a result of the research, the proposal of some indicators that could be applied and that would help to reduce the social and environmental impact is presented; besides reducing the amount of open-pit mining projects . The normative framework of Mexico is used as an example because it has a broader scope for the purpose of this work . It is concluded that the mining activity strengthens and creates economic structural dependencies for most of the countries that practice it, for which it expresses the need to suspend this practice gradually because it harms the environmental, social and economic aspects .

During the last decades, the impetuous growth and development of the Asian economies in general and particularly of the Chinese economy has led to a significant increase in the demand for raw materials . Thus, the new economic scenario has impact the performance of the gross domestic product and the export matrix of Latin America . In this line, this article analyzes the meaning and new role that the external sector acquires in Latin America as a consequence of the remarkable increase in commercial exchange . Using descriptive statistics, it is shown that due to the increase in the value of exports, both the purchasing power and the terms of trade are developed in favor of the countries of the region .

The teaching of economic science must respond both to the training of pro-fessional economists and to a dynamic approach to the economic topics taught and learned . Traditionally, classical mathematical analysis has been the formal instrument to address the complexity of economic phenomena . However, the very complex nature of economic phenomena requires different and comple-mentary approaches for a better apprehension of economic events, given their non-linearities, their circular behavior, their temporal lags and their emer-ging characteristics . A superficial review of the evolution of economic thought leads us to a very relevant conclusion: economists, over time, have not been influenced by systemic thinking when addressing the study of economic events, whether in the context of microeconomics as of the macroeconomics . The ma-turity reached by systemic science, in general, has been permeating the ideas of economists to the point of observing, in recent decades, more systemic con-cerns for the analysis of economic problems .Teachers and students of economic science will teach better and learn effi-ciently when grounding the teaching-learning processes in the systemic eco-nomy . Systemic thinking, as a philosophy of learning, as well as the dynamics of systems, as an instrument that facilitates practical implementation and dynamic simulation of behaviors, can provide extremely useful elements to improve the training of economists in locks based on the systemic economy .

El propósito de este artículo es sintetizar la evidencia de los avances del Programa Sistema de Protección Social en Salud (sPss) o Seguro Popular desde tres ámbitos: asignación de recursos públicos, acceso y cobertura de servicios de salud y protección financiera. La revisión narrativa de la literatura abarca estudios recientes e informa- ción de bases de datos oficiales para proporcionar una visión general de la cobertura universal del programa, desde su inicio en 2003. El estudio comprendió el análisis de la evolución del gasto salud público, la escala de afiliaciones de la población no asegurada y el impacto en la disminución del riesgo catastrófico por motivos de salud.
