We study how the migration from an old to a new technology is affected by the access price to the old technology. We show that both the incumbent and the regulator are willing to set a very high access price to accelerate consumers' migration to the new technology. When the quality of the old...

In this paper we study the results of three well-known experiments on duopoly markets, in which participants played a repeated market game in similar experimental conditions.We address two different questions: which learning theory is better able to describe the players' decisions in the...
