The network of global corporate control

Por • 25 oct, 2011 • Category: Economía

The structure of the control network of transnational corporations affects global market competition and financial stability. So far, only small national samples were studied and there was no appropriate methodology to assess control globally. We present the first investigation of the architecture of the international ownership network, along with the computation of the control held by each global player. We find that transnational corporations form a giant bow-tie structure and that a large portion of control flows to a small tightly-knit core of financial institutions. This core can be seen as an economic «super-entity» that raises new important issues both for researchers and policy makers.



Backbone of complex networks of corporations: The flow of control

Por • 23 oct, 2011 • Category: Economía

We present a methodology to extract the backbone of complex networks based on the weight and direction of links, as well as on nontopological properties of nodes. We show how the methodology can be applied in general to networks in which mass or energy is flowing along the links. In particular, the procedure enables us to address important questions in economics, namely, how control and wealth are structured and concentrated across national markets. We report on the first cross-country investigation of ownership networks, focusing on the stock markets of 48 countries around the world. On the one hand, our analysis confirms results expected on the basis of the literature on corporate control, namely, that in Anglo-Saxon countries control tends to be dispersed among numerous shareholders. On the other hand, it also reveals that in the same countries, control is found to be highly concentrated at the global level, namely, lying in the hands of very few important shareholders. Interestingly, the exact opposite is observed for European countries. These results have previously not been reported as they are not observable without the kind of network analysis developed here.

Es tiempo de un análisis de largo plazo mucho más sobrio, de juicios morales mucho más claros acerca de lo que el análisis revela, y de acciones políticas mucho más efectivas en el esfuerzo, en los próximos 20 o 30 años, para crear un mejor sistema-mundo que en el que estamos atorados ahora.



Libia en el gran juego

importaciones de Libia, seguida por China, Turquía y Alemania.
Este marco ahora revienta como resultado de lo que se puede caracterizar no como una revuelta de masas empobrecidas, como las rebeliones en Egipto y Túnez, sino como una verdadera guerra civil, debida a una división del grupo gobernante. Quienquiera que diese el primer paso ha explotado el descontento contra el clan de Gadafi, que prevalece sobre todo entre las poblaciones de Cirenaica y los jóvenes en las ciudades, en un momento en el cual todo el norte de África ha tomado el camino de la rebelión. A diferencia de Egipto y Túnez, sin embargo, el levantamiento libio se planificó y organizó con anterioridad.
