Information and communication technology sector developments in European and United States metropolitan areas

In the USA, several studies have been published that attempt to construct a comprehensive index of the new economy at both the state and metropolitan levels.1 The index is based on indicators of knowledge jobs, globalization, economic dynamism, the digital economy, and innovation capacity in each region. There have also been recent attempts to examine Internet use at the state and metropolitan levels in the USA (Forman, Goldfarb and Greenstein, 2002).
