How does Bond Market View IT investments of Firms? An Empirical Evidence of Bond Ratings and Yield Spreads

This study investigates the business value of information technology (IT) in terms of performance in bond markets, which constitute the single largest source for firms’ financing. We evaluate risk-adjusted benefits of IT investments in the bond market in the United States over the 1995-2002 period. We find a significant association between a firm’s IT intensity and bond ratings at issuance. The results also indicate that the impact of IT on the cost of debt is different across industries. IT investments have a favorable influence on the cost of debt in automate and informate industries but not in transform industries. This finding from the bond markets differs from that in prior equity market findings which report higher returns to IT investments in transform industries. These findings suggest that bondholders and shareholders have different perspectives toward IT investments

Self-organized Pattern Formation in Motor-Microtubule Mixtures

We propose and study a hydrodynamic model for pattern formation in mixtures of molecular motors and microtubules. The steady state patterns we obtain in different regimes of parameter space include arrangements of vortices and asters separately as well as aster-vortex mixtures and fully disordered states. Such stable steady states are observed in experiments in vitro. The sequence of patterns obtained in the experiments can be associated with smooth trajectories in a non-equilibrium phase diagram for our model.Comment: 11 pages Latex file, 2 figures include

Industry-Specific Human Capital and Wages: Evidence from the Business Process Outsourcing Industry

Human capital is becoming more critical as the global economy becomes more information intensive and service intensive. While IS researchers have studied some dimensions of human capital, the role of industry-specific human capital has remained understudied. The IT-enabled business process outsourcing (BPO) industry provides an ideal setting to study returns to human capital, because jobs in this industry are standardized and many professionals in this new industry have come from other industries. We build on IS and Economics literature to theorize returns to human capital in the BPO industry, and we test the theory using data for over 2,500 BPO professionals engaged in call center work and other non-voice services (e.g., accounting, finance, HR, etc.) in India during the 2006-2008 time period. We find higher returns to industry-specific human capital than to firm-specific and general human capital. We also find that junior-level professionals, whose jobs are relatively more standardized, have higher returns to industry-specific human capital than senior-level professionals. We discuss implications for further research and practice in the global economy where inter-industry transfers and migration of skills are becoming increasingly common

Does the Choice of Metric Matter for Identifying Areas for Policy Priority? An Empirical Assessment Using Child Undernutrition in India

Abstract: Ratio-based prevalence and absolute headcounts are the two most commonly accepted metrics to measure the burden of various socioeconomic phenomenon. However, ratio-based prevalence, calculated as the number of cases with certain conditions relative to the total population, is by far the most widely used to rank burden and consequently for targeting, across different populations, often defined in terms of geographical areas. In this regard, targeting areas exclusively based on prevalence-based metric poses certain fundamental difficulties with some serious policy implications. Drawing the data from the National Family Health Survey 2015–2016, and Census 2011, this paper takes four indicators of child undernutrition in India as an example to examine two contextual questions: first, does the choice of metric matter for targeting areas for reducing child undernutrition in India? and second; which metric should be used to facilitate comparisons and targeting across variable populations? Our findings suggest a moderate correlation between prevalence estimates and absolute headcounts implying that choice of metric does matter when targeting child undernutrition. Huge variations were observed between prevalence-based and absolute count-based ranking of the districts. In fact, in various cases, districts with the highest absolute number of undernourished children were ranked as relatively lower-burden districts based on prevalence. A simple comparison between the two approaches—when applied to targeting undernourished children in India—indicates that prevalence-based prioritization may miss high-burden areas where substantially higher number of undernourished children are concentrated. For developing populous countries like India, which is already grappling with high levels of maternal and child malnutrition and poor health infrastructure along with intrinsic socioeconomic inequalities, it is critical to adopt an appropriate metric for effective targeting and prioritization

A Comprehensive Review of Neuromuscular Manifestations of COVID-19 and Management of Pre-Existing Neuromuscular Disorders in Children

Since the emergence of SARS-CoV-2, several studies have been published describing neuromuscular manifestations of the disease, as well as management of pre-existing pediatric neuromuscular disorders during the COVID-19 pandemic. These disorders include muscular dystrophies, myasthenic syndromes, peripheral nerve disorders, and spinal muscular atrophy. Such patients are a vulnerable population due to frequent complications such as scoliosis, cardiomyopathy, and restrictive lung disease that put them at risk of severe complications of COVID-19. In this review, neuromuscular manifestations of COVID-19 in children and the management of pre-existing pediatric neuromuscular disorders during the COVID-19 pandemic are discussed. We also review strategies to alleviate pandemic-associated disruptions in clinical care and research, including the emerging role of telemedicine and telerehabilitation to address the continued special needs of these patients
