The Nd doped LaB6 and La doped NdB6 was successfully synthesized from La2O3–B2O3–Mg blends by mechanochemical method. The Nd doped affects on crystal structure and electronic features were studied employing DFT. The high-energy ball milling carried out the synthesis reaction. The process...

The study of information and communications technology (ICT) adoption signals that diffusion processes within highly unequal societies produces a strati cation in the access to digital technologies and thus, maintains or even increases previous socio-economic disparities. Whereas technological...

In this paper we investigate whether human capital accumulation, during adolescence, depends on home investments in Information and Communication Technologies (ICT) equipment. Using micro-level data, for children aged 17-18 years old, drawn from the Greek part of the European Union Statistics on...

This report takes stock of current ICT procurement practices in Chile, Colombia, and Mexico, focusing on vendor neutrality and market engagement in the purchase of personal computers and laptops. It also provides recommendations for improving access, competition, and market knowledge for...

This paper provides new estimates of depreciation rates for personal computers using an extensive database of prices of used PCs. Our results show that PCs lose roughly half their remaining value, on average, with each additional year of use. We decompose that decline into age-related...

Using a unique and comprehensive data source, we measure price changes for Microsoft's desktop personal computer software products during the time period July 1993 through June 2001. This paper contributes to a relatively small literature on price measurement of pre-packaged software by...
