When we spoke of multipliers of benefits, we spoke of four great areas that we will analyze with more thoroughness in the next articles and that do that companies of recent creation like Google, Amazon, Ebay, or Meetic, to speak of companies that use the Network mainly, can spectacularly be beneficial in relatively short periods of times. First of them it has to do with a very determining concept of the economy in network and the intangible ones: the increasing yields. The second multiplier is based on the capacity to construct entrance barriers that they block to the competitors during a time. After all, if we have innovated and the model is successful, we will have the monopoly of the market by a brief period of time and, in the measurement that entrance barriers exist, this period will be longer. The third multiplying drift of the existence in the model of strategic economies (of scale, specialization or generalization). Finally, and essential in an economy in constant change, the fourth multiplier comes defined by the strategic flexibility from the model, is to say the possibility of changing on the march if therefore it requests the market.
