Abstract
Purpose
The purpose of this study is to provide a new way to optimize a portfolio and to show that combining the Hurst exponent and wavelet analysis may help to increase portfolio returns.
Design/methodology/approach
The authors use the Hurst exponent and wavelet analysis to study the long-term dependencies between sovereign bonds and sectoral indices of India. The authors further construct and evaluate the performance of three portfolios constructed on the basis of Hurst standard deviation (SD) – global minimum variance (GMV), most diversified portfolio (MDP) and equal risk contribution (ERC).
Findings
The authors find that an ERC portfolio generates positive superior return as compared other two. Since our sample includes periods of two crisis – post-2007 financial crisis and the ongoing pandemic, this study reveals that combining government bond with equities and gold provides a higher returns when the portfolios are constructed using the risk exposures of each asset in the overall portfolio risk.
Practical implications
The findings provide guidance to portfolio managers by helping them to select assets using the Hurst approach and wavelet analysis thereby increasing the portfolio returns.
Originality/value
In this study, the authors use a combination of Hurst exponent and wavelet analysis to understand the long-term dependencies among various assets and provide a new methodology to optimize a portfolio. As far as the authors’ knowledge, no study in the past has attempted to provide a joint framework for portfolio optimization and therefore this study is the first to apply this methodology.

Abstract
Purpose
The purpose of this study is to understand how the business environment of a country has an impact on cash management policies of the firms and also to investigate if there is any asymmetry in cash adjustment dynamics when a firm deviates from its long-term target of cash holdings.
Design/methodology/approach
Using a sample of seven emerging Asian countries in the period 2001–2019, the authors investigate the role of country specific variables in the corporate cash holdings and their cash adjustment mechanism. They use the panel data regression method to estimate the results.
Findings
The authors find that the overall financial development of a country has a significant impact on corporate cash holdings and cash adjustment dynamics. When a firm has excess cash, the speed of adjustment towards the target is faster as compared to when it has deficit cash holdings. Further, when a firm holds excess cash, it adjusts towards the target using cash from investments; in case of deficit cash holdings, the adjustment happens via cash from financing activities.
Practical implications
The results of the study are helpful to corporate managers as these are important references to them to understand and design cash management policies by considering factors that are measured at the country level. It also provides them a clearer understanding about the role of corporate board and information asymmetry in cash holdings.
Originality/value
This is the first study which examines the role of country-specific variables on corporate cash holdings and their adjustment mechanism of firms in emerging Asia. Further, the study extends the literature by providing new evidence that there is asymmetry in cash adjustment dynamics of firms after controlling for the overall financial development of a country.

Abstract
Purpose
The purpose of this paper is to reveal the influence of social media in the development of brand sacralization in young consumers in emerging Asian market. Brand sacralization is the phenomenon where consumers (especially young) become an adherent of brands and consider brands as sacred entities. The paper specifically explores the influence of social media interaction and social media usability on brand sacralization and consequently its influence on online purchase intention (PI) and brand loyalty.
Design/methodology/approach
Perceptual responses were gathered from 232 undergraduate and postgraduate students (age: 17-27 years) studying in an Indian private university and is subsequently analyzed using structural equation modeling. The young population is chosen as the target sample as they possess majority stake in final product purchase decision nowadays and also contribute as a dominant consumer category in online market places.
Findings
The researcher found a strong positive influence of social media interaction and social media usability on brand sacralization. Further, brand sacralization is found to have a positive and significant influence on online PI and brand loyalty of young consumers. However, social media interaction does not contribute significantly to usability of social media. The researcher has also found a significant influence of brand loyalty on online PI for these young shoppers.
Originality/value
The study is the foremost to investigate the influence of social media in developing brand sacralization and its influence on online PI and brand loyalty. Further the study is the first to develop a measurement instrument for brand sacralization. The study is the foremost in developing measures for social media interaction and social media usability.

Abstract
Purpose
With the emergence of COVID-19 and increased infections, organizations urged their employees to work from home. Furthermore, with the on-going pandemic, employees take measures to ensure individual safety and their families. Hence, work from home culture can result in long-term employee satisfaction. However, no study addresses the development of work from the home culture in an integrated framework. Therefore, the current research explores the role of safety during the pandemic, organizational commitment and employee motivation on work from home culture, which may influence employee satisfaction. Furthermore, job demands and home demands were also evaluated for employee satisfaction.
Design/methodology/approach
The study used existing scales of the factors to develop the measures and collect perceptual responses from employees working from home, supported with a pre-test. The study executed a survey with effective responses from 132 individuals spread across different sectors to validate the hypotheses. The responses were analysed using partial least squares in ADANCO 2.2.
Findings
Findings suggest safety concerns along with organization commitment enhances work from home culture. Such work from home culture enhances employee motivation and employee satisfaction. Furthermore, job demands and home demands also influence employee satisfaction.
Originality/value
To the best of the authors knowledge, the study is the foremost to develop an integrated empirical framework for work from home culture and its antecedents and consequences. The study has several important implications for managers.

Abstract
Purpose
Recent studies have classified ecotourism behaviour into specific components like site-specific ecological, pro-environmental and environmental learning behaviour. However, the role of materialism in generating these types of behaviour is not clearly understood. Materialism might also affect tourists' environmental engagement. Hence, this study embarks on exploring these research gaps.
Design/methodology/approach
All the constructs were operationalized as first-order factors based on extant scales of measurement. After suitable pretesting, the study was able to collect 122 valid responses. The responses were analysed using partial least squares (PLS).
Findings
Results suggest that environmental engagement and environmental learning behaviour have prominent roles as enablers. Furthermore, the importance of materialism is not statistically significant and requires further investigation.
Research limitations/implications
While the study showed that environmental engagement is a crucial precursor for the development of different types of ecotourism behaviour, it also has limitations. First, the study tested the validity of the proposed associations based on the perceptual responses of 122 tourists who are interested in participating in ecotourism. However, this may lack generalizability. Future research can take a common set of tourists or a specific destination and execute a longitudinal analysis to better understand the way ecotourism behaviour has evolved over time at a destination. This would in turn help the local people and tour planners to develop tourism packages and events.
Practical implications
As tourists are interested in environmental learning, they are eventually expected to take care of the destination environment in terms of protecting it in every form. This may include reporting of any environment damaging activity, for example, activities that can enhance environmental pollution, etc.
Social implications
Materialism hinders the environmental conservation spree of tourists, when they indulge more in shopping and leisure trips. Hence, for destination planners it is very important to hold complementary events in addition to the main event to highlight the dire need of involving in ecotourism activities.
Originality/value
The study is of significant contribution for researchers and practitioners as it develops the antecedents and consequences of environmental learning behaviour. Furthermore, this study has implications for managers working for sustainability of tourism destinations.

Abstract
Purpose
This study explored the enabler role of novelty-seeking and materialistic values on technology-based outcomes: usefulness, ease of use and enjoyment of virtual tourism. Furthermore, this study explored the direct effects of Gen Z’s word-of-mouth intentions. The study also explored the contingent effects of gender and educational level.
Design/methodology/approach
Survey-based responses were gathered from 342 Gen Z participants using specific filtering criteria to ensure sample representativeness. Subsequently, the final responses were analysed using partial least squares.
Findings
The findings suggest a significant role for novelty-seeking and materialistic values in Gen Z’s overall perception of virtual tourism. Furthermore, with higher perceived usefulness, ease of use and enjoyment, Gen Zs are more inclined to share positive word-of-mouth for virtual tourism experiences.
Originality/value
This study aims to explore the orientation of Gen Zs toward virtual travel experiences in an emerging economy such as India. Implications for managers and practitioners are also discussed.
