Globalisation and over-supplied markets impose new behaviour to achieve stable performance, with corporate strategies based on: downsizing, networking, merging, development of intangibles. Global markets redefine competition space (market-space competition) and assert global managerial economics which interfaces with a competition space where markets are open and highly permeable to information; trade conditions development with an active role as intermediary on a global scale; and finally, companies –manufacturing, commercial and retail– grow with networking models.
