ABSTRACT
Even it is not a new one, learning, as a field of research, is becoming an increasingly important topic in economics. Indeed, Arrow (1962) introduces the idea that individuals were learning by doing, before Rosenberg (1982) says that the process of learning by using was much more relevant. Thereafter learning by interacting, institutional learning, and organizational learning and learning by learning were introduced in order to explain how, in an evolutionary perspective, technologies, organizations and institutions were changing. However, learning in economics recently becomes an important topic per se. In other words, learning is not just a means to explain how innovations or some other economic phenomena are taking place and evolving but is much more a way to explain how individuals modify their behaviour.
