Heat waves or Meteor showers: Empirical evidence from the stock markets

In order to study the volatility spillovers / the transfer of volatilities from spot and futures markets for the period 1st January 2001 to 30th November 2005 with high frequency data i.e., one minute intervals, we have used GARCH models to compute volatilities and VAR models for the returns of different markets and for the volatilities. It is evident that, these VAR models for the volatilities can exhibit the nature of the change in volatility. In a heat wave, the conditional variance of the returns in spot (futures) market depends only upon the past shocks in the given market. For meteor showers, the impact of shocks on spot (futures) markets are transferred from other i.e., futures (spot) markets. With the VAR (1)-GARCH (1,1) analysis, we found that both series are I(1) and that a bi-directional relationship exists between the spot and future market return series. Empirically it is evident that both heat waves and meteor showers exist in Indian spot and futures markets.Volatility Spillovers, Heat Waves, Meteor Showers, Indian Stock Market.

Are stock exchanges integrated in the world? - A critical Analysis

In the recent rapid reforms made the global into a global village in nature and in terms of efficiency, transparency. The information flow in one market may affect the other markets in the world, because of its integration. In this regard, this paper explores the objective whether there is any integration of markets taken place or not. For reaching the objective, we have used rigorous time series techniques for the equal period of data (1st January, 2001 to 30th April, 2009) of 17 stock exchanges in the world, which includes Asia, Europe, north America, Latin America etc.,. Our findings are markets within the region are well integrated both in terms of short run and long run equilibrium, because of its less cross-country restrictions. Many of the markets are showing granger causal relations between each other.Stock Markets, Cointegration, Economic Reforms

Measurement of Efficiency of Banks in India

In modern world, performance of banking is more important to stable the economy. In order to see the efficiency of Indian banks we have used four indicators i.e, profitability, productivity, asset quality and financial management for all banks include public, private and foreign banks in India for the period 1999-2000 to 2002-2003. For measuring the efficiency of banks we have adopted DEA (Data Envelopment Analysis) and found that public sector banks are more efficient than other banks operating in India

Antiviral therapy for herpes simplex virus encephalitis: Systematic review and meta-analysis of randomized control trials

Background: Herpes simplex virus (HSV) infection of the brain is treated with antiviral drugs such as acyclovir. A summary of randomized control trials (RCTs) of antiviral drugs against HSV encephalitis has not been put forward yet. We aimed to determine the effect of antiviral agents in treating HSV encephalitis on mortality and neurological sequelae at approximately 2 years. The secondary objective was to assess the adverse effect of antiviral agents on the patients. Materials and Methods: RCTs were identified by searching PUBMED, European Medicines Agency ( EMA ), USFDA, US Clinical trials, Elsevier database, and Cochrane website and the reference lists of published trials. Randomized controlled trials of antiviral therapy in biologically proven HSV infection were included in the study. Results: A total of 5 studies met the criteria. The first study was published in 1980 and the latest was in 2015. All the studies used acyclovir/valacyclovir or vidarabine. Three studies compared acyclovir and vidarabine, one study was placebo-controlled vidarabine trial and another one was a placebo-controlled trial of long-term valacyclovir therapy. Acyclovir improved mortality and lowered the incidence of neurological sequelae. There was no significant reduction in the risk of mortality with vidarabine therapy. Conclusion: Trial evidence suggests that acyclovir decreases mortality and morbidity in acute HSV encephalitis
