This research aims to contribute to the understanding of local socio-economic phenomena, particularly those related to labor, developed in relation to some of the main dynamics of today’s globalization. The analysis focuses on social relationships of production and reproduction that characterize the assembly industry for export in the border area between Mexico and the United States. Specifically, we examine the socio-economic model through which Foxconn operates in Ciudad Juarez (Chihuahua, Mexico). This multinational company – which, despite its Taiwanese origins has grown together with the economy of mainland China – holds roughly 50% of the electronics production market worldwide and has become the paradigm of a new phenomenon of economic expansion – not only from a quantitative, but also from a qualitative point of view. The research draws data from a six-month period of fieldwork. Five months were spent in the Mexican city of Ciudad Juarez and its suburbs (a few kilometers from the border with the United States), where the vast majority of ethnographic observations and interviews were conducted, and a month was spent in El Paso, the United States city adjacent to Ciudad Juarez. 49 key informants were interviewed, including 22 women and 27 men; 35 interviews were conducted with Foxconn’s workers and 2 with ex-workers, among which 18 were women and 19 men. Additionally, 12 key informants (business executives, government officials, representatives of the local association of employers and of social and community organizations), were interviewed, of which 8 were men and 4 were women. The research analyzes the socio-economic dynamics that, in a short period, have converted the Mexico-United States border into a central location of global economic development, characterized by a remarkable industrial and demographic concentration, which have transformed the metropolitan area of El Paso - Ciudad Juarez into one of the most populous and industrialized cross-border areas in the world. In addition to the socio-economic features of the territory, the research analyzes the globalized processes that, beginning in the Sixties, have contributed crucially to the massive growth of the so-called maquiladora industry. Central to the research is the analysis of the numerous and profound changes which occurred in the local structure of social relations. The main research interest is the analysis of “labor informalization”, a category which is not related to the growth of the so-called “informal economy”, but to the development of mechanisms of informalization within the regulatory framework of the so-called “legal” or “registered” economy, in which the role played by local actors is critical. Finally, considering the sociological immanence of labor (which, under capitalism, is set up as a primary role, determining the social positioning of individuals in various relational networks and hierarchies), the research explores the transformations and the phenomena that characterize the sphere of reproduction, trying to explain the ways in which this sphere interpenetrates and influences the dynamics of globalized production, and vice versa. The profound changes in gender roles, the militarization of the whole border area, local territorial conflicts, the spread of poverty and urban precariousness, the emergence of a powerful “necroeconomy” and “necropolitics” – primarily, but not exclusively, indicated by feminicidios and juvenicidios –, the exponentially increased power of organized crime and the loss of the Mexican State’s ‘monopoly on violence’ in vast areas of the country emerge as fundamental dynamics in the constitution of the sphere of reproduction, where workers of today's globalized electronics industry carry out their the daily life.
