Description
Summary:We examine the relationship between the deployment of broadband, which we classify as a general purpose technology, and the productivity of the deploying firms using panel data that comprises information on all the major local exchange carriers in the United States telecommunications industry from 1995 to 2000. This relationship is an important indicator of the economic impact of new technology adoption. We provide a comprehensive analysis of the literature on general purpose technologies as well as on the economic consequences of information and communications technology diffusion and develop a framework to empirically assess the impact of broadband deployment on the productivity. Our results find a positive relationship between broadband deployment and the carriers’ productivity and suggest that encouraging the deployment of broadband technologies, in addition to the benefits to consumers and firms at the receiving end of the new technology, create the potential for better technological efficiencies and increased productivity for the deploying firms. The benefits can be enhanced as the firms studied operate in two-sided markets where the network effects brought about by the multitude of interconnections can be substantial because of possible second-order spillovers of productivity.
