The current problems in mobile telephony are leading critics to make overly pessimistic predictions that 3G – the third-generation mobile phone system – will never become profitable. However, the resulting calls not to introduce 3G and instead directly back alternative wireless technologies...

It became clear early on that UMTS, also known as 3G (third-generation mobile phone systems), would be a key technology for profitable markets of the future. However UMTS technology offers some major advantages that can be demonstrated under laboratory conditions but which it will not be...

We may distinguish between two concepts of technology: a theoretical level of technology (that is, a technology possibilities frontier) and a level of technology in practice (that is, ready to use in production technology). Having these two concepts in mind, the paper develops an intertemporal...

Utilising panel data for 14 East European transition economies, we find support for the hypothesis that a greater degree of export variety relative to the U.S. helps to explain relative per capita GDP levels. The empirical work relies upon some direct measures of product variety calculated from...
