Information Technology Externalities: Empirical Evidence from 42 U.S. Industries

Using interindustry transaction in input-output tables, we examine Information Technology (IT) externalities in U.S. private industries over the period 1984-2000. Our empirical results show that computerization of an industry's customer and supplier industries reduces both labor and material costs of the industry. Moreover, cost savings driven by supplier industries are larger than those driven by customer industries. We also find that industries in the services sector enjoy more benefits from IT spillovers than industries in other sectors because of their high IT capital intensity and composition of interindustry transaction. Decomposition of total factor productivity (TFP) suggests that IT externalities can explain considerable parts of TFP growth, although possible mismeasurement of output in services industries leads to exacerbated technical changes of services industries.INFORMATION TECHNOLOGY; NETWORK EXTERNALITY; INPUT-OUTPUT TABLE; TOTAL FACTOR PRODUCTIVITY

Experimental Setup for the Measurement of the Thermoelectric Power in Zero and Applied Magnetic Field

An experimental setup was developed for the measurement of the thermoelectric power (TEP, Seebeck coefficient) in the temperature range from 2 to 350 K and magnetic fields up to 140 kOe. The system was built to fit in a commercial cryostat and is versatile, accurate and automated; using two heaters and two thermometers increases the accuracy of the TEP measurement. High density data of temperature sweeps from 2 to 350 K can be acquired in under 16 hours and high density data of isothermal field sweeps from 0 to 140 kOe can be obtained in under 2 hours. Calibrations for the system have been performed on a platinum wire and Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+\delta}$ high $T_{c}$ superconductors. The measured TEP of phosphor-bronze (voltage lead wire) turns to be very small, where the absolute TEP value of phosphor-bronze wire is much less than 0.5 $\mu$V/K below 80 K. For copper and platinum wires measured against to the phosphor-bronze wire, the agreement between measured results and the literature data is good. To demonstrate the applied magnetic field response of the system, we report measurements of the TEP on single crystal samples of LaAgSb$_{2}$ and CeAgSb$_{2}$ in fields up to 140 kOe.Comment: 10 pages, 8 figures. accepted in Measurement Science and Technolog

Impact of Carbon Price Policies on U.S. Industry

This paper informs the discussion of carbon price policies by examining the potential for adverse impacts on domestic industries, with a focus on detailed sector-level analysis. The assumed policy scenario involves a unilateral economy-wide $10/ton CO2 charge without accompanying border tax adjustments or other complementary policies. Four modeling approaches are developed as a proxy for the different time horizons over which firms can pass through added costs, change input mix, adopt new technologies, and reallocate capital. Overall, we find that a readily identifiable set of industries experience particularly adverse impacts as measured by reduced output and that the relative burdens on different industries are remarkably consistent across the four time horizons. Output rebounds considerably over longer time horizons, and the adverse impacts on profits diminish even more rapidly in most cases. Over the short term employment losses mirror output declines, while gains in other industries fully offset the losses over the longer horizons. At the same time, leakage abroad is considerable in some sectors, particularly when reductions in exports are considered.carbon price, competitiveness, input-output analysis

Will the U.S. productivity resurgence continue?

U.S. productivity growth has accelerated in recent years, despite a series of negative economic shocks. An analysis of the sources of this growth over the 1995-2003 period suggests that the production and use of information technology account for a large share of the gains. The authors project that during the next decade, private sector productivity growth will continue at a rate of 2.6 percent per year, a significant increase from their 2002 projection of 2.2 percent growth.Productivity ; Information technology

Comments on "Vortex Glass and Lattice Melting Transitions in a YNi_2B_2C Single Crystal"

Recently, Mun et.al. (Phys. Rev. Lett., 76, 2790 (1996)) have published their results on single crystal YNi_2B_2C, claiming that their experimental observations can be explained in terms of formation of Vortex Glass and Lattice melting. Our experiments, carried out on samples obtained from the SAME source, reveal a much richer phase diagram and span wider regions of experimental parameter space than Mun et. al. that encompasses most of their observations. We speculate that this material has anomalous intrinsic properties and the results cannot be explained by simple models about the flux lattice.Comment: 1 page, LaTeX type, 1 PostScript figure, Uses PRABIB.STY file, 600 dpi PS file available at http://sagar.physics.neu.edu/preprints.html To appear in Physical Review Letter

Projecting productivity growth: lessons from the U.S. growth resurgence

Following the 1995-2000 period of more rapid output growth and lower inflation in the United States, economists have strenuously debated whether improvements in economic performance can be sustained. The recession that began in March 2001 intensified the debate, and the economic impacts of the events of September 11 have yet to be fully understood. Both factors add to the considerable uncertainties about future growth that currently face decision makers in both the public and private sectors. ; In this article, the authors analyze the sources of U.S. labor productivity growth in the post-1995 period and present projections for both output and labor productivity growth for the next decade. Despite the 2001 downward revisions to U.S. gross domestic product and software investment, the authors show that information technology (IT) played a substantial role in the U.S. productivity revival. The article then outlines a methodology for projecting trend output and productivity growth. The base-case projection puts the rate of trend productivity growth at 2.21 percent per year over the next decade with a range of 1.33 to 2.92 percent, reflecting fundamental uncertainties about the rate of technological progress in IT-production and investment patterns. The central projection is only slightly below the average growth rate of 2.36 percent during the 1995-2000 period.Productivity ; Technology ; Economic development

Buddhism, Uncertainty and Modernity in A Hometown in Heart

A Hometown in Heart (Maeumui gohyang, 1949), written by Ham Sedeok (1915-1950) and directed by Yun Yonggyu (b.1913), is said to be the first Korean Buddhist film. It depicts Buddhism in a remote mountain region without even electricity. The main character of the film, an orphaned child monk, must decide what to do with his life. This paper argues that the central aspect of the Buddhism-related symbols represent Korean tradition and that the supporting characters represent socio-political forces in post-liberation Korean society just after liberation, pulling the young generation of Koreans in various directions. In particular, the film centers on feelings of uncertainty, anxiety, and avoidance pressing challenges of a rapidly changing world. The authors explore what the film tells us about the filmmakers’ view of these anxieties and the role Buddhism plays in solving them. To this end, the article examines shared motifs found in Korean cinematic history. These motifs include the orphan, nostalgia, modernity, and karma. The article finds that while the film advocates breaking away from tradition to engage the modern industrialized world, it does so by supporting the notion that we all carry the most important aspects of Buddhism within our hearts. This is symbolized in the film by the Heart Sutra and the Red Lotus iconography of Mahayana Buddhism. The article concludes with a comparison of the period-specific elements in A Hometown in Heart and those in its 2002 remake, A Little Monk, directed by Ju Gyeongjung (b. 1959)

The Korean Buddhist Nun Chiyul (Jiyul) and Ecofeminism: Hunger Strikes, the Lawsuit for Salamanders, and Walking Protests

Chiyul (b. 1957), a nun of the Chogye Order of Korean Buddhism, led protests against government construction of a KTX (Korea Train eXpress) tunnel passing through Mt. Ch’ŏnsŏng between 2002 and 2006 and participated in protests against the government’s nationwide four major rivers restoration project between 2008 and 2012, focusing on the Nakdong River. She has made serious efforts to protect environment as a nun in the culturally and institutionally sexist South Korean Buddhist order in particular and in the culturally, not institutionally, sexist South Korean society in general. She, when on hunger strikes five times totaling more than 341 days, filed along with environmental activists a lawsuit on behalf of salamanders living on the mountain and against the tunnel construction, and petitioned the government to take a proper environmental impact assessment. Although the courts would have accepted an unreasonable assessment of the environmental impact construction of the tunnel on the mountain and ruled in favor of the government\u27s project, Chiyul and environmental activists made Koreans pay attention to the importance of these and related issues through legal procedures. In her later protests against the government’s restoration project, she adopted more moderate walking protests than hunger strikes and lawsuits, possibly due to the failure to stop the government though her earlier radical protests
