Economia digital, redes eletrônicas e novas modalidades de concorrência : o caso do Google

Abstract

The core question in this paper is to study the digital economy. The main differences between this one and the industrial economy are: the information is the main input and output; the network effect is more usual and the price competition is not anymore so relevant. In this sense, this study presents three levels of analyze: first level, more abstract, shows the information s specificities; second level, shows theoretical questions about network economy and competition; and, at last, in a concrete level, shows the Google s competition strategy, trying to observe the explanation power of the theories discussed.
