Technology Diffusion and Business Cycle Asymmetry

The goal of this paper is to theoretically account for business cycle asymmetries of deepness and steepness. The former means that recessions are deeper than expansions are tall, and the latter that recessions are steeper than expansions. In this paper I introduce the process of technology diffusion and learning like general purpose technology in the framework of real business cycles. I assume that a positive technology shock diffuses over the economy with some time lag, while a negative one does without any lag. Generally, a positive shock can be literally interpreted as an innovation to technology. Economic agents may take some time to adopt a new technology and learn how to use the technology efficiently. In contrast, a negative shock can immediately decrease the level or growth of productivity. No learning is needed to suffer a loss of productivity induced by a negative shock. A positive shock makes the near-future level of productivity higher than the present level as a result of technology diffusion. Because of intertemporal substitution behavior, it leads to a recession in the present and then the subsequent expansion. In contrast, a negative innovation is assumed to immediately generate a recession. When an S-shaped diffusion is assumed, a positive shock can induce a deeper and steeper recession. This gives a theoretical explanation of deepness and steepness asymmetries.Keywords: Technology Diffusion; Intertemporal Substitution; Real Business Cycles.

Munchausen by internet: current research and future directions.

The Internet has revolutionized the health world, enabling self-diagnosis and online support to take place irrespective of time or location. Alongside the positive aspects for an individual's health from making use of the Internet, debate has intensified on how the increasing use of Web technology might have a negative impact on patients, caregivers, and practitioners. One such negative health-related behavior is Munchausen by Internet

Penelope: The NBTI-aware processor

Transistors consist of lower number of atoms with every technology generation. Such atoms may be displaced due to the stress caused by high temperature, frequency and current, leading to failures. NBTI (negative bias temperature instability) is one of the most important sources of failure affecting transistors. NBTI degrades PMOS transistors whenever the voltage at the gate is negative (logic inputPeer ReviewedPostprint (published version

Positive and negative sides of technology

Nowadays, we cannot imagine our life without technology. 100 years ago people didn’t even hear about computers, cars and other electrical devices. But now we cannot live comfortably and easily without them. These different devices are necessary in our daily routine. Also, technology can solve problems of designing, inventing, building things such as products, houses, bridges and others. Technology affects us and the environment both positively and negatively.

Serving higher education with technology – disrupting higher education with technology

Technology is increasingly serving higher education by enabling student-centred learning and concerted social learning, extended reach to content anytime and everywhere, insights for educators into progress tracking and learning trends, and cross-institutional academic collaboration. At the same time, technology is providing evidence of negative disruption to the core purpose of education, which is human development and individual preparation for the future. Technology is gradually diminishing the capacity of individuals to critically think and reason, to expand into unfamiliar knowledge domains, and to exploit the learning experience to fulfil the market needs after graduation. In this paper, a review is presented on how technology is disrupting higher education, both positively and negatively. Some recommendations are given with respect to these disruption

Adiabatic Mach-Zehnder interferometry on a quantized Bose-Josephson junction

We propose a scheme to achieve Mach-Zehnder interferometry using a quantized Bose-Josephson junction with a negative charging energy. The quantum adiabatic evolution through a dynamical bifurcation is used to accomplish the beam splitting and recombination. The negative charging energy ensures the existence of a path-entangled state which enhances the phase measurement precision to the Heisenberg limit. A feasible detection procedure is also presented. The scheme should be realizable with current technology

Factor demand linkages, technology shocks, and the business cycle

This paper argues that factor demand linkages can be important for the transmission of both sectoral and aggregate shocks. We show this using a panel of highly disaggregated manufacturing sectors together with sectoral structural VARs. When sectoral interactions are explicitly accounted for, a contemporaneous technology shock to all manufacturing sectors implies a positive response in both output and hours at the aggregate level. Otherwise there is a negative correlation, as in much of the existing literature. Furthermore, we find that technology shocks are important drivers of the business cycle

Censorship: the Key to Lock-In?

Markets for information and entertainment are frequently characterized by increasing returns to scale in production and distribution. This implies that incumbent technologies enjoy an advantage over newcomer technologies; such markets can become locked into an inferior technology. Governments often heavily influence media markets through both direct ownership and censorship. I present a dynamic model with heterogeneity among consumers and firms in order to analyze the role of censorship in media markets. I assume there is a negative consumption externality across consumers and a negative cost spillover which an incumbent producer imposes on a newcomer. In a decentralized equilibrium, there is over-production of media from the incumbent technology. This reduces consumer utility and engenders lock-in of the inferior incumbent technology. I model censorship as a tax on information produced under the incumbent technology. A central planner who censors incumbent media can improve upon the decentralized equilibrium by reducing negative consumption externalities and unlocking the superior technology. I also show that censorship is only Pareto optimal when coupled with lump-sum transfers across consumers.

Process and IT (Editorial)

Purpose – This paper’s aim is to provide a fresh perspective on how to address process improvement and information technology (IT) in an integrated fashion in order to improve the efficiency of the construction process. Design/methodology/approach –This paper looks at the problems associated with the “conventional” way of addressing IT within construction, and suggests improvements based on integrating three core organisational resources: people, process and technology. Findings – The existing view that IT on its own brings organisational benefits leads to only marginal improvements in organisational efficiency if not resulting in negative impact. However, by correctly integrating people, process and IT initiatives, significant benefits can be achieved. Originality/value – This paper provides value by providing a conceptualisation for addressing people, process and technology within the construction sector
