Abstract This report accompanies the work performed by Southwest Research Institute (SwRI) in collaboration with the National Highway Traffic Safety Administration on fuel efficiency and emissions reduction technologies. Technologies are evaluated for medium- and heavy-duty vehicles for model years 2019 and beyond. Based on the list of technologies and configurations identified by SwRI, this report examines the costs of implementation in constant 2011 U.S. dollars in the areas of incremental retail prices and life cycle cost elements. Incremental retail prices are evaluated relative to the prices of the specific baseline technologies that would otherwise be used in the vehicles if the fuel efficiency and emissions reduction technologies were not implemented. These prices include the technology components as well as their installation and incorporation in the vehicle. These prices account for all costs associated with the manufacturers and suppliers’ production and sale of the technologies to the retail purchaser. The life cycle cost element examines the costs of using the technologies during the vehicles’ lifetimes and are intended to inform separate, full-scale, life-cycle analysis. This report provides the overall details of the costing methodology and findings of the study. Note: This report was subjected to external peer review per OMB guidelines for a Highly Influential Scientific Assessment (HISA). Material from the peer review process are publicly available in accompanying documents. 17. Key Words 18.

  • TECHNOLOGY and POLICY DRIVERS of the FUEL ECONOMY of NEW LIGHT-DUTY VEHICLES Comparative Analysis Across Selected Automotive Markets
    TECHNOLOGY AND POLICY DRIVERS OF THE FUEL ECONOMY OF NEW LIGHT-DUTY VEHICLES Comparative analysis across selected automotive markets Working Paper 12 UNEP INTERNATIONAL ENERGY AGENCY The International Energy Agency (IEA), an autonomous agency, was established in November 1974. Its primary mandate was – and is – two-fold: to promote energy security amongst its member countries through collective response to physical disruptions in oil supply, and provide authoritative research and analysis on ways to ensure reliable, affordable and clean energy for its 29 member countries and beyond. The IEA carries out a comprehensive programme of energy co-operation among its member countries, each of which is obliged to hold oil stocks equivalent to 90 days of its net imports. The Agency’s aims include the following objectives: n Secure member countries’ access to reliable and ample supplies of all forms of energy; in particular, through maintaining effective emergency response capabilities in case of oil supply disruptions. n Promote sustainable energy policies that spur economic growth and environmental protection in a global context – particularly in terms of reducing greenhouse-gas emissions that contribute to climate change. n Improve transparency of international markets through collection and analysis of energy data. n Support global collaboration on energy technology to secure future energy supplies and mitigate their environmental impact, including through improved energy efficiency and development and deployment of low-carbon technologies.

  • The Impacts of Technological Invention on Economic Growth – a Review of the Literature Andrew Reamer1 February 28, 2014
    THE GEORGE WASHINGTON INSTITUTE OF PUBLIC POLICY The Impacts of Technological Invention on Economic Growth – A Review of the Literature Andrew Reamer1 February 28, 2014 I. Introduction In their recently published book, The Second Machine Age, Erik Brynjolfsson and Andrew McAfee rely on economist Paul Krugman to explain the connection between invention and growth: Paul Krugman speaks for many, if not most, economists when he says, “Productivity isn’t everything, but in the long run it’s almost everything.” Why? Because, he explains, “A country’s ability to improve its standard of living over time depends almost entirely on its ability to raise its output per worker”—in other words, the number of hours of labor it takes to produce everything, from automobiles to zippers, that we produce. Most countries don’t have extensive mineral wealth or oil reserves, and thus can’t get rich by exporting them. So the only viable way for societies to become wealthier—to improve the standard of living available to its people—is for their companies and workers to keep getting more output from the same number of inputs, in other words more goods and services from the same number of people. Innovation is how this productivity growth happens.2 For decades, economists and economic historians have sought to improve their understanding of the role of technological invention in economic growth. As in many fields of inventive endeavor, their efforts required time to develop and mature. In the last five years, these efforts have reached a point where they are generating robust, substantive, and intellectually interesting findings, to the benefit of those interested in promoting growth-enhancing invention in the U.S.

Some Key Areas for Innovation . 201 Annex A: Annex Tables . 208 References . 219 CHINA‘S GROWTH THROUGH TECHNOLOGICAL CONVERGENCE AND INNOVATION 163 Executive Summary Income gaps among countries are largely explained by differences in productivity . By raising the capital/labor ratio and rapidly assimilating technologies across a wide range of activities, China has increased factor productivity manifold since 1980 and entered the ranks of middle income countries . With the launch of the 12th FYP, China has re-affirmed its goal of becoming a mod- erately prosperous society by 2020 . This report maintains that China can become a high income country by 2030 through a strategy combining high levels of investment with rapid advances in technology comparable to that of Japan from the 1960s through the 1970s and Korea’s from the 1980s through the end of the century . During the next decade, more of the gains in productiv- ity are likely to derive from technology absorption and adaptation supplemented by incremental innovation, while high levels of investment will remain an important source of growth in China through deepening and embodied technological change . By 2030, China expects to have pulled abreast technologically of the most advanced countries and increasingly, its growth will be paced by innovation which pushes outwards the technology frontier in areas of acquired comparative advantage .

  • Industrial Development and Growth in Nigeria: Lessons and Challenges
    Working Paper No. 8 Industrial development and growth in Nigeria: Lessons and challenges L. N. Chete, J. O. Adeoti, F. M. Adeyinka, and O. Ogundele* Abstract The structure of the Nigerian economy is typical of an underdeveloped country. The primary sector, in particular, the oil and gas sector, dominates the gross domestic product accounting for over 95 per cent of export earnings and about 85 per cent of government revenue between 2011 and 2012. The industrial sector accounts for 6 per cent of economic activity while the manufacturing sector contributed only 4 per cent to GDP in 2011. The economic transformation agenda, otherwise known as Nigeria Vision 20: 2020, sets the direction for the current industrial policy in Nigeria. The industrialization strategy aims at achieving greater global competitiveness in the production of processed and manufactured goods by linking industrial activity with primary sector activity, domestic and foreign trade, and service activity.

  • Assistive Technology for Students with Autism Spectrum Disorders
    National Association of Special Education Teachers AUTISM SPECTRUM DISORDER SERIES Assistive Technology for Students with Autism Spectrum Disorders Introduction For years, different modes of technology have been used to improve the quality of life of people who have various developmental disabilities . However, the varied use of technology for children with autism continues to receive limited attention, despite the fact that technology tends to be a high interest area for many of these children. This issue of the Autism Spectrum Disorder Series will discuss how various modes of technology (including technology designed as augmentative communication systems), can be used for children with autism to increase or improve their: Overall understanding of their environment Expressive communication skills Social interaction skills Attention skills Motivation skills Organization skills Academic skills Self help skills Overall independent daily functioning skills What is Assistive Technology? According to the Technology-Related Assistance for Individuals with Disabilities Act of 1988 (Public Law 100-407), an assistive technology means any item, piece of equipment, or product system, whether acquired commercially, off-the-shelf, modified or customized, that is used to increase, maintain, or improve functional capabilities of individuals with disabilities. Assistive technology service is any service that directly assists an individual with a disability in the selection, acquisition, or use of an assistive technology device. Typically, children with autism process visual information easier than auditory information. Any time we use assistive technology devices with these children, we're giving them information through their strongest processing area (visual). Therefore various types of technology from "low" tech to "high" tech, should be incorporated into every aspect of daily living in order to improve the functional capabilities of children with autism.
