This paper examines a large-scale randomized evaluation of the One Laptop Per Child (OLPC) program in 531 rural primary schools, as implemented by the Peruvian government starting in 2009. We use administrative and survey data on academic achievement and grade progression through 2019 to...

The closing of schools and shift to remote teaching during the COVID-19 pandemic has accelerated the use of digital technology in education. Many schools today provide personal computers not only to older students, but also in primary school. There is little credible evidence on how one-to-one...

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...

In this paper we examine the importance of local spillovers such as network externalities and learning from others in the diffusion of home computers using data on 110,000 U.S. households in 1997. Controlling for many individual characteristics, we find that people are more likely to buy their...

Results of hedonic price regressions for personal computer operating systems and productivity suites advertised in PC World magazine by retail vendors during the time period 1984 to 2000 are reported. Among the quality attribute variables we use are new measures capturing the presence of network...

Improvements in the software that provides hardware management, user interface and platform functions have played a central role in the growth and transformation of the personal computer (PC) industry. Several forces shape the design of these 'operating system' products and propel their...
