    Abstract: Machinery and equipment (M&E) is one of the imperative factors that influence Canada’s living standards. M&E investment and development is vital for long-term productivity growth. Despite Canada’s resilience to the global financial crisis, it is still vulnerable to weak future growth due to lingering economic frailties such as low productivity. Canada trails in investment and adoption of information and communications technology (ICT), a sub-group of M&E and the foundation for technological advancement in today’s digital world, compared to a number of advanced economies. Our findings indicate lower investment in ICT combined with lower competition, lower spending in R&D, and barriers to foreign direct investment to be significant factors to Canada’s low productivity. To ensure that sustainable living standards are attained in the future, Canada will need to improve its productivity level, and increasing investment in M&E is an important part of it.

    Abstract: The microblogging social networks (µBSNs) can serve to motivate students by narrowing the physical and psychological distances separating teachers and students, thus increasing their confidence and engagement in the learning process. To examine this issue in greater depth, an experiment was carried out using a µBSN before, during and after face-to-face class sessions. The findings demonstrated that the extended TAM model (with subjective norms and social images constructs) is suitable for explaining the acceptance of web-based teaching tools as well as the validity of microblogging networks in combination with traditional classes.

    Abstract: "In the project 'Combined firm data for Germany' (KombiFiD) firm data from different institutions were merged and made available for research for the first time. The institutions involved in the project faced considerable challenges both due to the narrow legal limits underlying such a merging procedure and as a result of the partial lack of a unique identifier. This paper provides an overview of the objectives associated with the project and its progress." (Author's abstract, IAB-Doku) ((en))

    Abstract: Although many countries are aggressively implementing the One Laptop per Child (OLPC) program, there is a lack of empirical evidence on its effects. This paper presents the impact of the first large-scale randomized evaluation of the OLPC program, using data collected after 15 months of implementation in 319 primary schools in rural Peru. The results indicate that the program increased the ratio of computers per student from 0. 12 to 1. 18 in treatment schools. This expansion in access translated into substantial increases in use both at school and at home. No evidence is found of effects on enrollment and test scores in Math and Language. Some positive effects are found, however, in general cognitive skills as measured by Raven’s Progressive Matrices, a verbal fluency test and a Coding test.
