Purpose – The purpose of this paper is to perform an analysis of potential benefits from usage of the futures markets for the farmers. The national commodity exchanges were established in India in the year 2003-2004. Though there has been a spectacular growth in trading volumes in these exchanges, participation of farmers in these markets has been very low. Efforts are being made to increase the awareness and participation of farmers in these markets. As such efforts are being made, it is critical to analyse the potential benefits from usage of the futures markets for the farmers. Our study performs such an analysis for soybean farmers in the Dewas district of Madhya Pradesh state in India. Design/methodology/approach – The authors estimate the optimal hedge ratios in futures markets for farmers in different scenarios characterised by varying levels of different parameters relevant to the farmer. For these optimal hedge ratios, we then estimate the benefits from hedging defined as the change in certainty equivalent income (CEI) due to hedging. Findings – Results indicate that the CEI gain due to hedging is positively related to the farmer’s risk aversion and inversely related to farmer’s price expectations and transaction costs. Also, only when the risk aversion is high, the CEI gain is positively related to the natural hedge. Thus, for a farmer with high risk aversion, hedging acts as a substitute to the natural hedge. Originality/value – This is the first study that analyses the hedging for farmer in the Indian context by considering yield risk while doing so. Also, their study establishes a relationship between risk aversion, the natural hedge and benefits from hedging in futures markets for the farmer.

Purpose This paper aims to investigate the efficiency of different hedging strategies for an investor holding a portfolio of foreign currency bonds. Design/methodology/approach The simplest strategies of no hedge and fully hedged are compared with the more sophisticated strategies of the ordinary least squares (OLS) approach and the optimal hedge ratios found by the dynamic conditional correlation-generalised autoregressive conditional heteroskedasticity approach. Findings The sophisticated hedging strategies are found to be superior to the simple strategies because they lower the portfolio risk in domestic currency terms and improve the Sharpe ratios for multi-asset portfolios. The analyses also show that both the OLS and dynamic hedging strategies imply holding a limited carry position by being long in high-yielding currencies but short in low-yielding currencies. Originality/value The performance of multi-currency portfolios is examined using more realistic assumptions than in the previous literature, including a weekly frequency and a constraint of no short selling. Furthermore, carry trades are shown to be part of an optimal portfolio.

This empirical study utilizes four static hedging models (OLS Minimum Variance Hedge Ratio, Mean-Variance Hedge Ratio, Sharpe Hedge Ratio, and MEG Hedge Ratio) and one dynamic hedging model (bivariate GARCH Minimum Variance Hedge Ratio) to find the optimal hedge ratios for Taiwan Stock Index Futures, S&P 500 Stock Index Futures, Nikkei 225 Stock Index Futures, Hang Seng Index Futures, Singapore Straits Times Index Futures, and Korean KOSPI 200 Index Futures. The effectiveness of these ratios is also evaluated. The results indicate that the methods of conducting optimal hedging in different markets are not identical. However, the empirical results confirm that stock index futures are effective direct hedging instruments, regardless of hedging schemes or hedging horizons.

PurposeIn a first place, the present paper is designed to examine the dynamic correlations persistent between five cryptocurrencies, WTI, Gold, VIX and four stock markets (SP500, FTSE, NIKKEI and MSCIEM). In a second place, it investigates the relevant optimal hedging strategy.Design/methodology/approachEmpirically, the authors examine how WTI, Gold, VIX and five cryptocurrencies can be applicable to hedge the four stock markets. Three variants of multivariate GARCH models (DCC, ADCC and GO-GARCH) are implemented to estimate dynamic optimal hedge ratios.FindingsThe reached findings prove that both of the Bitcoin and Gold turn out to display remarkable hedging commodity features, while the other assets appear to demonstrate a rather noticeable disposition to act as diversifiers. Moreover, the results show that the VIX turns out to stand as the most effectively appropriate instrument, fit for hedging the stock market indices various related refits. Furthermore, the results prove that the hedging strategy instrument was indifferent for FTSE and NIKKEI stock while for the American and emerging markets, the hedging strategy was reversed from the pre-cryptocurrency crash to the during cryptocurrency crash period.Originality/valueThe first paper's empirical contribution lies in analyzing emerging cross-hedge ratios with financial assets and compare hedging effectiveness within the period of crash and the period before Bitcoin crash as well as the sensitivity of results to refits choose to compare between short term hedging strategy and long-term one.

Purpose – The purpose of this paper is to determine and contrast the risk mitigating effectiveness from optimal multiproduct time-varying hedge ratios, applied to the margin of a cattle feedlot operation, over single commodity time-varying and naive hedge ratios. Design/methodology/approach – A parsimonious regime-switching dynamic correlations (RSDC) model is estimated in two-stages, where the dynamic correlations among prices of numerous commodities vary proportionally between two different regimes/levels. This property simplifies estimation methods for a large number of parameters involved. Findings – There is significant evidence that resulting simultaneous correlations among the prices (spot and futures) for each commodity attain different levels along the time-series. Second, for in and out-of-sample data there is a substantial reduction in the operation's margin variance provided from both multiproduct and single time-varying optimal hedge ratios over naive hedge ratios. Lastly, risk mitigation is attained at a lower cost given that average optimal multiproduct and single time-varying hedge ratios obtained for corn, feeder cattle and live cattle are significantly below the naive full hedge ratio. Research limitations/implications – The application studied is limited in that once a hedge position has been set at a particular period, it is not possible to modify or update at a subsequent period. Practical implications – Agricultural producers, specifically cattle feeders, may profit from a tool using improved techniques to determine hedge ratios by considering a larger amount of up-to-date information. Moreover, these agents may apply hedge ratios significantly lower than one and thus mitigate risk at lower costs. Originality/value – Feedlot operators will benefit from the potential implementation of this parsimonious RSDC model for their hedging operations, as it provides average optimal hedge ratios significantly lower than one and sizeable advantages in margin risk mitigation.

Optimal Hedge

Purpose This paper aims to attempt to re-capture the stock market contagion effect from the US to the BRIC equity markets during the recent global financial crisis in a multivariate framework. Apart from this, the study also identifies optimal portfolio hedging strategies to minimize the underlying portfolio risk during the period undertaken for the purpose of study. Design/methodology/approach To account for the dynamic interactions, the study uses vector autoregression (p) dynamic conditional correlation (DCC)-asymmetric generalized autoregressive conditional heteroskedastic (1,1) model in a multivariate framework, coupled with a monthly heat map relating to the co-movement between the US and the BRIC equity markets during the period 2007-2009. Finally, by following the studies, Hammoudeh et al. (2010) and Syriopoulos et al. (2015), the time-varying optimal portfolio hedge ratios and weights are computed. Findings The results report a contagion impact of the US subprime crisis (following the collapse of the Lehman Brothers) on the Indian and Russian stock markets only. On the other hand, a higher degree of interdependence between the US and Brazilian market has been observed. The US and Chinese equity markets indicate a relatively lower level of interdependence among themselves. The optimal hedge ratios are found to be most effective for a portfolio comprising the US and Chinese stocks even during the crisis period. A US investor should invest approximately 30 cents in the Indian market and rest of the 70 cents in the US market in a US$1 portfolio to minimize the portfolio risk without lowering the expected returns. During the crisis period (2007-2009), the optimal portfolio weights indicate a higher weightage to the BRIC stocks. Practical implications The results support the construction of optimal US–BRIC stock portfolios and provide an insight to the investors and policy makers both domestic as well as international, with regard to the contagion impact and interdependence, especially during a crisis period. Originality/value The study uses a DCC model in a multivariate framework instead of bivariate, wherein all the markets are factored into a single interaction framework across a very long period (2004-2014). Second, a heat map of monthly correlation combinations has been created for the period 2007-2009, to comprehend the contagion impact or interdependence among the markets. Finally, the study ascertains time-varying optimal hedge ratios and portfolio weights for a two asset portfolio, from a US investor viewpoint, making the study first of its kind in all the perspectives.

Abstract Crop revenue insurance is unique, because it involves a guarantee subsuming yield risk and highly systematic price risk. This study examines whether crop insurers could use options instead of, or in addition to, assigning policies to the Commercial Funds of the USDA Federal Crop Insurance Corporation (FCIC) as per the Standard Reinsurance Agreement (SRA) to hedge the price risk of revenue insurance policies. The behavioral model examines the optimal hedge ratio for a crop insurer with a book of business consisting of corn Revenue Protection (RP) policies. Results show that a mix of put and call options can hedge the price risk of the RP policies. The higher optimal hedge ratios of call options as compared to put options imply that the risk of increased liability due to upside price risk can be hedged using options better than downside price risk. This study also analyzed the combination of options with the SRA at 35, 50, and 75% retention levels. The zero optimal hedge ratios at each retention level and the negative correlation between RP indemnities and the option returns when the crop insurer mixed options and SRA suggest that the purchasing of options provides no additional risk protection to crop insurers beyond what is provided by the SRA despite retention limits.

Policies And Practices

PurposeThe Indian context is marked with weak anti-discrimination laws and patchy implementation of protection of civil rights of women at workplaces. The purpose of this paper is to unearth the rationales of the adoption of gender diversity management policies and practices in India, in the absence of laws and regulations.Design/methodology/approachInspiration is drawn from previous studies on diversity management in other national contexts, and a survey methodology was adopted. The lead researcher administered the questionnaires personally to all respondents to ensure that the understanding of the questions is uniform across respondents as gender diversity management is a relatively new concept in India.FindingsSize of the organisation (number of full-time employees), the influence of external organisations and perceived enhanced organisational flexibility were found to explain the adoption of gender diversity management policies and practices in the Indian IT/ITeS industry. Findings also indicate that Indian subsidiaries of foreign multinationals tend to adopt more gender diversity management policies and practices as compared to Indian-owned organisations.Research implicationsThis study provides evidence that organisations do not always enact structures or behaviours in the pursuit of normative rationality and also consider the economic value of them, establishing an organisational agency in adopting legitimated norms or practices. The study also shows that gender diversity management policies and practices are not only dependent on the enactment of laws but also are adopted because of the economic benefit perceived.Originality/valueDiversity management policies and practices have been mostly studied in national contexts with anti-discrimination laws or affirmative action programs and have been claimed to be a successor of equal employment opportunity (EEO) policies. In the absence of stringent laws to reduce or eliminate discrimination against women employees in Indian workplaces, this study contributes to the literature by determining whether the business case for gender diversity drives the adoption of gender diversity management in the Indian context.
