 The Nash Equilibrium says that if no strategy provides a benefit to a player given that all other players maintain their strategies, then that set of strategies and the payoffs are in a Nash Equilibrium. So can you explain to me how adopting or not adopting the data standard affects that equilibrium? Are you saying that in such an equilibrium, nothing changes unless the whole industry changes? Or that nothing changes until some threshold of the number of installed software systems of a given type use that standard? Given, one first tracks the industry leaders (not the customers) to see if planning is taking place (planning indicates commitment to act), then tracks the number of installations up to that threshold (basically, colonization of the niche). The actions of the customers are an external force that may prompt the movement in industry and puncture the equilibrium, ok; but to be really effective, a stronger force is needed since customers tend to maximize their local conditions; therefore, aren't much of a force. Even the Beltway lead initiatives tend to dissipate without legal teeth. Without a moral imperative stronger than their market imperative, it's difficult to predict what they will do. Of course, when a gorilla enters the market, things change quickly because the gorilla can use tactics such as forcing prices to zero, and then the equilibrium bursts if that offering is compelling. Free browsers were one example of that. (Look at the costs of hypermedia tools prior to Mosaic.) len From: Didier PH Martin [mailto:martind@n...] I think that XML based domain languages or data structure will reach some success when groups perceive that they have to reach some form of cooperation in order to lower the overall costs. A good example of such behavior may be XBRL (1) in the financial domain. By experience, I discovered that if no external constrain is applied by a pressure group or by economic constraints, then people do not behave according to Nash equilibrium and therefore act as Adam smith creatures and think of their own benefit without thinking about the overall system. Walter's thesis may be right when applied to groups behaving in accordance to Adam Smith creatures and may be wrong in accordance to groups behaving in accordance to Nash's equilibrium.
