RESUMEN
One of the main features of economic elites are the links and networks among them. I focus on these networks. Corporate networks are built when large corporations establish relationships among each other by sharing directors (interlocking directorates). The configuration of these corporate networks draws and maps how economic power is structured around the world. I do a cross-national analysis of corporate networks among twelve countries: Germany, Spain, France, Italy, the Netherlands, Sweden, Switzerland, United Kingdom, USA, Canada, Australia and Japan. I focus on financial structure, state intervention, ownership structure and FDI to explain differences and similarities among corporate networks. Results show different institutional environments where large corporations are embedded, pointing out varieties of capitalism. I distinguish four kinds of capitalism: Network-based, Market-based, Midway and Japanese and I argue about importance of international interlocking directorates to explain institutional change.
