In this paper we analyze the relative importance and mutual behavior of two competing base-load electricity generation options that each are capable of contributing significantly to the abatement of global CO2 emissions: nuclear energy and coal-based power production complemented with CO2...

This paper analyzes the contribution of network externalities to the pickup in U.S. productivity in the early 2000s. The Internet and wireless communication are treated as the central mechanisms of ICT-driven productivity growth. The approach contrasts with the dominant view in the...
