The bulk of the global innovative effort takes place in 5 countries: USA, Japan and China as leaders, with France and United Kingdom as immediate followers, which all display, on the long run, a negative marginal value added on innovation. The present paper attempts to answer the following question: why does most of innovative activity takes place in markets apparently hostile to innovation, i.e. giving back negative marginal value added on innovation? A model is introduced in which any market may be represented as a Selten's extensive game, subgames of which are played as Harsanyi's games with imperfect information, by a temporarily finite and changing set of players.
