Spillover analysis across FinTech,ESG, and renewable energy indices before and during the Russia–Ukraine war: International evidence

This study is epicentral to analyze the impact of the Russia–Ukraine war on the financial markets, specifically focusing on the connectedness and spillover dynamics of FinTech, Environmental, Social, and Governance (ESG), renewable energy, gold, and Morgan Stanley Capital International (MSCI) indices in developed and emerging countries. Data are collected from Thomson Reuters, ranging from May 8, 2020, to May 11, 2022, and a time-varying parameter vector autoregression (TVP-VAR) and the dynamic conditional correlation (DCC) generalized autoregressive conditional heteroskedasticity (GARCH) t-Copula (DCC-GARCH t-Copula) are used to analyze the data. The results show that FinTech, ESG, and MSCI are net transmitters in developed countries, whereas gold and renewable energy are net receivers pre- and during war periods. ESG and MSCI are net transmitters in emerging countries, while FinTech, renewable energy, and gold become net receivers in both periods. The hedging ratio sheds light on the costs and weights of efficient pair investments that might change in the context of each region and under the combined scenario. The study has important implications for merchant bankers, policymakers, investors, hedgers, and risk managers.     

COLLECTIVELY GARDENING THE URBAN PUBLIC SPACE IN MEXICO CITY: When Informal Practices Interact with the State

In recent years, a growing number of citizen-led gardens have appeared in the urban public spaces of large cities across the world. While many of these projects are initially launched informally without any support from the state, they gradually become integrated into the social fabric of the city. To understand the evolution of the formal–informal boundaries of the practice, we argue that we should be paying attention to the specific institutional contexts that frame gardeners’ interactions with public authorities. Drawing from a study of citizen-led gardens in Mexico City, we show that informal urban gardening becomes a disconnected-from-the-state practice. On the one hand, the Mexico City government has shown a growing interest in regulating urban agriculture. On the other hand, gardeners are increasingly trying to find their own ways to formalize and perennate their practice. We suggest that this disconnection between gardeners and the state is best explained by the weakness of the institutional context in which their interactions take place. A top-down policymaking process, along with the incapacity and unwillingness of the multi-leveled city government to implement policies effectively, reinforces norms of mistrust and generates low expectations among gardeners as they interact with local authorities.     

Human–machine trans roles conflict in the organization: How sensitive are customers to intelligent robots replacing the human workforce?

In organizations facing digital transformation, intelligent technologies are starting to replace the human workforce. At present, managers delegate tasks to an artificial agent and rarely consider the customer reception of such decisions. This arouses tensions between the main stakeholders of the organization. This paper shows that the rash adaptation of the digital workforce may be perceived as an irresponsible innovation that brings negative consequences for companies. If a task is regarded by customers as dedicated to humans, and managers delegate it to machines, a new type of conflict – human-machine trans roles conflict (HMTRC), appears. This paper intends to show that customers are sensitive to HMTRC. This research uses quantitative methods and consists of three stages. First, people were asked to indicate which tasks in an organization should be performed by (a) humans and (b) machines. According to these results, two leaflets for customers were designed (low vs. high HMTRC). In the second stage, standard procedures were used to construct a scale measuring customer reactions to HMTRC on three dimensions: cognitive, emotional and behavioural. Ultimately, the scale and two leaflets were used to check how customers react to different intensities of HMTRC. The research results show that customers are aware when HMTRC occurs and perceive it negatively (cognitive response). Moreover, it evokes negative emotions (emotional response) and prompts customers to take action against the company in which this conflict takes place (behavioural response). The practical contribution of this research is the three-dimensional scale. It may predict customers' reactions to task delegation with different intensities of HMTRC and help build a technologically sustainable organization.     

Consumption coping strategies and well-being among refugee consumers

This paper aims to provide new insight into refugee consumers' adaptation to stress with a particular emphasis on consumption coping strategies and well-being. Drawing on the appraisal-coping theory, this paper proposes a theoretical framework relating stress to coping responses and refugee well-being. Social support is also introduced in the framework as a moderator. Examining the interplays between these concepts provides a comprehensive view of how changes in consumption patterns occur and how they affect refugee well-being. Insights from this paper suggest that consumption activities could be viewed as responses of adaptation to chronic and acute stress. To adapt to new circumstances and reduce their stress, refugee consumers could engage in adaptive consumption coping or maladaptive consumption coping (i.e., compulsive and impulsive consumption), which in turn affect their psychological and physical, family, and economic well-being. The paper contends that service support moderates the relationships between stress, coping responses, and refugee well-being.
