Purpose– This paper aims to examine the destabilization effect in the case of India's agricultural commodity market for the sample period of 01 January 2009 to 31 May 2013.Design/methodology/approach– The daily data of eight agricultural commodities traded on the National Commodity & Derivatives Exchange, viz., barley, castor seed, chana (chickpea), chilli, potato, pepper, refined soya and soybean, have been used in this study. At the first stage of the empirical analysis, the study estimates the time-varying spot market volatility by using the exponential generalized autoregressive conditional heteroscedasticity model and applies three different high and band-pass filters, viz., the two-sided linear band-pass filter by Hodrick and Prescott (1997), the fixed-length symmetric band-pass filter by Baxter and King (1999) and the asymmetric band-pass filter by Christiano and Fitzgerald (2003), to calculate the unexpected liquidity of sample commodities. At the second stage of the empirical analysis, the study applies linear Granger causality and recently developed non-linear causality given by Diks and Panchenko (2006) to examine the cause and effect between time-varying volatility of spot market and futures market liquidity of sample commodities.Findings– The linear and non-linear causality results suggest the destabilizing effect of commodity futures on the underlying spot market for chana, chilli and pepper. The empirical findings are in contrast with the recommendations of Abhijit Sen's committee and provide important direction for further policy research.Research limitations/implications– The study has a limitation in that it is based on the daily data. The use of intra-day data would have been more suitable for such type of analysis.Practical implications– The study has strong policy implications from a financial policy perspective, as there is already disagreement among researchers and policy makers with regard to the functioning of commodity derivatives markets in India. There have been many occasions when commodity market regulators have to undertake decisions of suspension of trading of many commodities. The study also provides new directions of policy research with regards to the restructuring of the commodity derivatives market in India.Social implications– The findings of this study may further help the regulators and policy makers to undertake decisions about how to provide an alternative platform for farmers to sell their agricultural produce more efficiently. This will certainly have some impact on the socioeconomic set-up of the country, as India is primarily an agriculture-dominated country.Originality/value– So far not many studies have investigated the destabilization hypothesis in the case of emerging markets. This study is a novel attempt to fill the gap. In the case of emerging markets and especially in the case of India's commodity derivatives market, this is the first study that examines the destabilization hypothesis in the case of India by applying new methods of high and band-pass filters and non-linear causality.

PurposeThe study investigates the impact of bank market competition and concentration on the bank default-risk using the data for 36 Indian scheduled commercial banks from 1999 to 2017.Design/methodology/approachThe study adopts the dynamic panel generalised method of moments (GMM) and panel quantile models to obtain the results.FindingsBank market competition and concentration foster financial fragility in terms of high default-risk. This implies that concentration does not mean a lack of competition in the Indian banking market. The findings from the quantile model reveal that the stated relationships become weaker under the tails of the conditional distribution of the risk measure.Research limitations/implicationsThe authors recommend that non-structural measures (Lerner index and H-statistic) should be preferred over the concentration measures (HHI and CR3) to characterise bank market competition in India. Based on the evidence of persistence in the bank risk variable, from the methodological perspective, dynamic panel data models are better choices for bank-level analyses compared to the conventional panel data models.Practical implicationsTo improve the health of banks, price competition should be reduced among them. This objective should be achieved by creating new avenues to increase the banks' non-interest income parallelly with the consolidation of the market.riginality/valueFirst, it tries to answer whether concentration implies a lack of competition for a banking system like India. Second, the quantile regression technique enables us to understand the varying nature of the impact of market competition on bank risk at different locations on the latter's conditional distribution. Earlier studies have not looked at these aspects in the Indian context.

BACKGROUND: Most of the parents have no idea that how and when they should educate about sexual health to their typically growing children. It is important for parents to educate their children with intellectual disability about sexual health. The risk of sexual exploitation and abuse is very high in individuals with intellectual disability. OBJECTIVE: The present study was conducted to find out the awareness among the parents of individuals with intellectual disability about sexual health education. MATERIALS AND METHODS: Subjects for the present study were the parents of individuals with intellectual disability studying at government rehabilitation institute for intellectual disabilities, chandigarh (n = 100). The present study is a cross-sectional study and subjects were selected by making use of random sampling technique. A Rating scale on "Awareness on sexual health education for parents of intellectually challenged children" developed by Lakshmi and Navya, (2014) was used. RESULTS: The results revealed that there is a significant difference in knowledge, attitude, and practice among the parents of individuals with intellectual disability about sexual health education. The significant difference with respect to the gender on awareness about sexual health education (knowledge, attitude, and practice) among the parents of individuals with intellectual disability was found. No significant difference with respect to family type on awareness about sexual health education was found. CONCLUSION: Parents who live in rural locality have responded greater on the knowledge and practice than those who live in urban locality. However, parents living in urban locality have scored more on attitude over the parents who live in rural locality.
