This book is the final report of the ECLAC-IDRC project Observatory for the Information Society in Latin American and the Caribbean OSILAC, which aims at understanding the dynamics of the ICT evolution and revolution and producing evidence on its potential to promote socio-economic development. As such, microdata analysis drawn from National Household Surveys and National Innovation Surveys in Latin America were used in the framework of the project in the attempt to reach those objectives. Both statistical information sources provide attractive potentialities in order to investigate not only determinants of innovation activities and technology diffusion, but also its economic impacts.
