Relative information functions and their type (α, β) generalizations

The concept of relative information functions by means of a functional equation under suitable boundary conditions is introduced and discussed. Further the relative information is defined in terms of these functions and this idea is extended to the new concept of relative information functions of type (α, β) (α, β>0, α≠β) and relative information of type (α,β) which are the generalizations of the earlier ones. Finally the different types of relative informations of type (α, β) are defined for bivariate distributions and the relations between them are established.     

Dealing with the Contagion： China and India in the Aftermath of the Subprime Meltdown

What began as a downturn in the US housing sector in the summer of 2007 had mushroomed into a global financial crisis by September 2008： the most severe since the 1930s. Developing countries, including China and India, at first seemingly sheltered from the worst of the turmoil, have not been immune to the contagion＇s spillover effects. What are China and India＇s precise vulnerabilities, and what can each do to better insulate their economies from the vagaries of global financial marker turmoil？ Equally important, what long-term strategies must each country adopt to make their economies more resilient to global market downturns？     

An Analysis of Exports and Growth in India: Cointegration and Causality Evidence (1971–2001)

The relationship between exports and economic growth has been analysed by a number of recent empirical studies. This paper re‐examines the sources of growth for the period 1971–2001 for India. It builds upon Feder's (1983 ) model to investigate empirically the relationship between export growth and GDP growth (the export led growth hypothesis), using recent data from the Reserve Bank of India, and by focusing on GDP growth and GDP growth net of exports. We investigate the following hypotheses: (i) whether exports, imports and GDP are cointegrated using the Johansen approach and Breitung's nonparametric cointegration test; (ii) whether export growth Granger causes GDP growth; (iii) and whether export growth Granger causes investment. Finally, a VAR is constructed and impulse response functions (IRFs) are employed to investigate the effects of macroeconomic shocks.     

Short-term fluctuations in hospital demand: implications for admission, discharge, and discriminatory behavior

We analyze admission and discharge decisions when hospitals become capacity constrained on high-demand days, and develop a test for discrimination that, under certain circumstances, does not require controls for differences across patient groups. On high-demand days, patients are discharged earlier than expected compared to those discharged on low-demand days. High demand creates no statistically significant differences in hospitals' admission behavior. Thus, hospitals appear to ration capacity by hastening discharges rather than by restricting admissions. We could not reject a null hypothesis of no discrimination against Medicaid patients in discharges     

Impulse buying and variety seeking: A trait-correlates perspective

Impulse buying and variety seeking are low-effort feelings-based behaviors, yet the similarities and differences in their socio-psychological origin are under-explored. This article addresses this gap with a conceptual framework incorporating several individual and situational factors with a focus on three relevant consumer traits — consumer impulsiveness (CI), optimum stimulation level (OSL), and self-monitoring (SM). Findings from a survey with retail shoppers about their actual purchase decisions show that both CI and OSL have a positive association with the level of impulse buying and variety seeking. However, CI is more strongly associated with impulse buying and OSL with variety seeking. Moreover, SM relates negatively with impulse buying and positively with variety seeking; it also moderates the influence of CI and OSL on both the behaviors in opposite directions. Finally, the article discusses the contribution of this research, its limitations and some directions for future research.     

Google: The World’s First Information Utility?

In only ten years, Google has achieved remarkable success from online search-based advertising. Its search engine is dominant, and its IT infrastructure is the most powerful computing system in the world running on over one million computers and serving more than one billion users globally. Google makes money by using its search engine to deliver online advertising alongside responses to user searches for information, goods, maps, directions, and a host of other services. Its capabilities make it likely to become the world’s first information utility – a concept similar to electric utilities that provide services to many corporations and individuals alike. Constant innovation is the key to Google’s success and offers lessons for other companies: hire talented people, have them work in small teams, and give them freedom to excel, but use a rigorous data-based approach to evaluating results and making course adjustments.

Colliding Employer‐Employee Perspectives of Employee Turnover: Evidence from a Born‐Global Industry

Set in the context of internationalization of the global division of labor, this article provides a deeper exploration of qualitative themes of conflicting accounts of employees’ reasons to quit and managerial strategies to prevent employee turnover in six business process outsourcing firms operating in India. Such differences in cognition and action between the two constituencies suggest that the decision to quit is not a linear and rational process as highlighted in most extant models of employee turnover. Our findings suggest that employees are attached more to a place or people they work with rather than the organization per se. Intergenerational differences between Generation Y knowledge workers and Generation X managers and the ineffectiveness of espoused human resource practices suggest the presence of “push” human resource management (HRM) systems. Our findings have implications for employee turnover models, intergenerational theory and high‐commitment HRM, and practitioners. © 2015 Wiley Periodicals, Inc.     

Improving portfolio diversification: Identifying the right baskets for putting your eggs

We measure the economic value of diversification for international multiasset investment strategies. This study implements five existing diversification measures and proposes a novel measure of diversification, the unsystematic risk ratio (URR). Only the URR and the effective number of bets measures predict the future risk‐adjusted performance. These relations are robust to the choice of investment horizon and degree of relative risk aversion. The diversification benefits are larger for the frontier and emerging markets than for the developed markets, for multiasset strategies than for single asset class strategies, and for the pre‐crisis and post‐crisis periods than for the financial crisis period.
