Since the mid-1990s, extraordinary advances in semiconductors have enhanced the embodied nature of information technology, fuelling efficiency growth in computers and communication equipment industries. The consequent fall in prices has enabled the rapid diffusion of these new technologies, which have reached the critical threshold to foster productivity growth. In light of the recent growth pattern of the United States, this paper presents a model where the endogenous engine of development is the learning-by-doing process stemming from the usage of ICT for investment and consumption.

Abstract
Since the mid-1990s, extraordinary advances in semiconductors have enhanced the embodied nature of information technology, fuelling efficiency growth in computers and communication equipment industries. The consequent fall in prices has enabled the rapid diffusion of these new technologies, which have reached the critical threshold to foster productivity growth. In light of the recent growth pattern of the United States, this paper presents a model where the endogenous engine of development is the learning-by-doing process stemming from the usage of ICT for investment and consumption. Based on a two-sector framework (à la Whelan) that distinguishes between ICT-producers and -users, the model yields a sound representation of the stylized facts of the Information Age.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
