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.

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).

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Tourism supply chains (SCs) are recently gaining importance and there is a dire need for empirical testing and theory development in allied areas. The current investigation aims to explore the importance of management learning, relationship development, shared vision, inter-firm integration and technology perception as essential management capabilities required for the development of dynamic capability of tourism SC agility. Furthermore, the study explores the agile influence on competitive advantage.

The study collected perceptual responses from 233 active participants and respondents in the tourism sector. The collected data were analyzed for the validity of the proposed relationships through partial least squares.

Findings suggest relationship development, shared vision, inter-firm integration and technology perception as significant enablers. Furthermore, tourism SC agility was found to enhance competitive advantage.

The study further advances theory development and empirical testing through extending the concept of agility to tourism SCs and examining its enablers. Furthermore, the study developed measured for the utilized enablers of tourism SC agility through appropriate development in tourism contexts.

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.

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 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.

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.

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.

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).

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.

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.

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.

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.

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.

This paper aims to explore the challenges faced by start-ups during COVID-19 and highlight solutions for catering to the new-normal consumer behaviour. The study accounts for 15 deep-tech start-ups sailing through the pandemic and their responsiveness. This study brings forth insights and experiences from the Indian start-up founders and CEOs during COVID-19.

This study uses a qualitative approach and is exploratory and phenomenological. A purposive sample of 15 young start-ups founded between the years 2013–2020 by founders aged between 24 and 41 was selected for the study. The recorded telephonic interview was collected from the founders from April 2021 to September 2021. The thematic analysis of the study evolves from Braun and Clarke (2006) using the MAXQDA 2020.

The study emphasizes upon challenges faced by start-ups, crisis management of start-ups and the relevance of technology-based start-ups during challenging times. This research provides a qualitative framework to establish the role of the technology acceptance model (TAM) towards the adaptability, responsiveness and resilience demonstrated by the start-ups. The findings also highlight the solutions to address challenges faced by start-ups and road to recovery.

The study has great relevance and lessons for budding entrepreneurs during crisis management. The study has implications for corporations and governments in terms of setting up incubators and accelerators to support budding entrepreneurs.

The study is unique in highlighting the relevance and importance of TAM for start-ups during crisis management like COVID-19. The study thrusts upon the need of technology acceptance for better crisis management.

The purpose of this paper is to delve into some of the key internal and external factors that led to the choice of specific strategies for union revitalization using the theoretical framework built upon framing perspectives, the strategic action field (SAF), and the strategic choice theory.

The authors used a stringent definition and corresponding operationalization of trade union revitalization. The present research has been carried out on a registered industrial union within the context of Global South, specifically in India.

Evidence was found for the trade union adopting a mix of strategies for revitalization, namely, union organizing, social movement unionism, and union restructuring. A mix of both internal and external factors identified informed the choice of revitalization strategies.

Specific limitations include the subjectivity of the inference in spite of taking due precautions, and lack of generalizability of the findings based on a single case study.

A strong identity, coupled with structural vitality and optimum use of resources enables trade unions to frame the need of a strategy for revival in order to counter the strategic action of employers resulting in union revitalization.

The theoretical novelty of this research stems from the amalgamation of collective action frames, SAF, and strategic choice framework to understand the union revitalization in the context of Global South.
