This study examines the influence of the global geopolitical risk (GPR) on the relationship between oil prices and domestic food prices under the augmented Phillips curve framework.

Using monthly data on Nigeria from January 1995 to December 2021, the authors accommodate symmetry and asymmetry by adopting the linear and nonlinear autoregressive distributed lag, linear and nonlinear Granger causality tests.

The study establishes the positive and significant effects of both oil prices and GPR on food prices in the long and short run, though with a small magnitude in the short run. The asymmetric model shows that, while oil price shocks (positive and negative) exert a positive influence on food prices in the long-run, the effects of oil price shocks differ when accounting for GPR in the short-run. The coefficients of the interactive term, being the moderator of GPR between oil-food prices, are positively significant across models, suggesting that they jointly influence food prices when assuming linearity. The nonlinear model shows that the positive and negative components of interactive terms exert a positively significant influence on food prices, even though food prices tend to be more reactive to positive oil price shocks. The robustness checks show a unidirectional causal flow from oil prices and GPR to food prices under the linear and nonlinear models.

The authors examine the moderating effect of the newly developed global GPR index of Caldara and Iacoviello (2022) on the oil–food inflation relationship in Nigeria by applying the symmetric and asymmetric approaches.

Oil price shocks greatly impact the global economy, but the effects vary among countries. While higher oil prices benefit oil-exporting countries, they harm the economic performance of oil-importing nations, and vice versa for lower oil prices. However, economic relations, such as trade, can mitigate the impacts of oil price shocks on both groups. In this paper, the authors aim at estimating the effects of oil price shocks on the major net oil-exporting and net oil-importing countries while accounting for international trade.

The authors derive a reduced form of a macro model and set up a Panel VAR model to estimate the direct and indirect impacts of oil price shocks on economic growth. The sample includes data on macroeconomic variables from 30 oil-exporting and oil-importing countries that comprise more than 73 percent of the world's economy. The authors construct the spillover variables using bilateral trade matrix. To control for institutional and structural variations across the countries, they are divided into four groups of developed and developing oil-exporting and oil-importing countries.

The results reveal that all oil-exporting countries have significantly benefited from oil price shocks, although trade has dampened the effect. The positive growth effect has been more pronounced in oil-exporting developing countries. The impact of oil price shocks on oil-importing countries has been negative with a one-year delay, but not statistically significant, and trade has only had a small effect. The effect has been more substantial in oil-importing developing countries.

One of the limitations of this study is the focus on trade as the main spillover channel. Given the data availability, other channels such as foreign investment and financial markets can also be included in future studies.

Removing trade restrictions would help both oil-exporting and oil-importing countries to mitigate the negative impacts of the oil price shocks. However, the asymmetric oil-macroeconomy relationship across oil-exporting and oil-importing countries puts oil-exporting countries in a more vulnerable position as they cannot rely on trade with oil-importing countries to reduce the negative impacts of lower oil prices on their growth. Therefore, it is crucial for oil-exporting countries to reassess their oil-dependent development plans and invest their oil revenues in non-oil sectors to diversity their economies and prepare for a future with reduced dependence on oil.

The recent technological advances, structural changes, and increasing energy efficiency suggest that major oil-importing countries will become less dependent on oil in near future. As a result, oil-exporting countries will also need to undergo structural changes in order to sustain their income level. These significant changes will have important social implications, particularly in the labor market, during the transition, for which preparation will be necessary.

While the literature on the total impact of oil price shocks on either oil-exporting or oil-importing countries is rich, studies on their spillover impacts are limited. Recent research has shown that trade and migration can affect the impact of oil price shock on the economy in federated countries such as Canada. However, the trade effect on oil price shocks in the international level, where countries are subject to different regulations/restrictions and institutional variations, remains scarce. By considering the trade relationship between different groups of oil-exporting and oil-importing countries, the authors aim to contribute to the literature of the global impacts of oil price shocks on the world economy.

The study examines how calculative practices and accountability appear in a rural community of marginalised people in Egypt who depend on jasmine plantations that contribute to the production of global essences.

The data were collected from various sources, namely conversations with villagers, documents and relevant videos and news available on social media and the Internet. This study draws on the concepts of social accountability, the politics of blame avoidance and using calculative practices as a language to explain accountability in context.

The author found a lack of accountability on the part of the government and business owners, with serious implications for the livelihoods of people in a community that has been wholly dependent on jasmine plantations for a century. Power holders have deployed a blame-shifting game to avoid social responsibility. In response, calculative practices rather than advanced accounting tools are used by the poor in the community to induce power holders to be accountable.

The findings of this study show that authorities need to take proactive steps to address the disadvantaged position of powerless people in the lower echelons of society, recognising their accountability for those people.

This paper enhances the understanding of the status of calculative practices and accountability in a community of marginalised people who contribute to the production of global commodities. The paper also enhances the understanding of what goes on behind the scenes with popular and prestigious commodities, whose development is initiated in poor countries, with the end product marketed in rich Western countries.

The purpose of this study was to explore the potential benefits of Coriandrum sativum (C. sativum) on anxiety, depression, sleep quality and memory among students.

This randomized controlled trial involved university students aged 18–25 years, who had no known allergies to C. sativum or were using psychotropic medication. After giving informed consent, participants were randomly assigned using a computer-generated random sequence to either 500 mg C. sativum seeds or a placebo. Primary outcomes measured changes in memory (prospective and retrospective memory questionnaire [PRMQ]), anxiety and depression (Hospital Anxiety and Depression Scale), while secondary outcomes assessed sleep quality (Pittsburgh sleep quality inventory [PSQI]).

A sample of 86 students with a mean age of 20.05 ± 1.6 years was selected for the study. Initial assessments ensured no significant differences in demographic or study variables between the control and intervention groups. Statistical analysis revealed significant improvements in memory (PRMQ: p = 0.006), anxiety (Hospital Anxiety Scale: p = 0.04) and depression (Hospital Depression Scale: p = 0.002), as well as in sleep quality (PSQI: p = 0.03) in the group receiving C. sativum compared to the control group.

This research offers initial insights into the potential benefits of C. sativum intake, specifically its role in enhancing memory performance and mitigating anxiety among student populations. The results present a compelling case for further research in this domain to solidify these preliminary conclusions.

This study examines the impact of perceived human resource management practices on talent turnover intention, with work engagement mediating and self-efficacy moderating the relationship. It examines how employees' perceptions of pay satisfaction, empowerment, participation and communication are related to their turnover intentions.

A total of 283 valid questionnaires from UAE government employees were used for data analysis. Partial least squares structural equation modeling (PLS-SEM) was used to examine the proposed hypothesis.

The results reveal that employees' perceptions of pay satisfaction, empowerment, participation and communication are significant contributors to work engagement. The findings further demonstrate that work engagement significantly negatively affects talent turnover intention and acts as a mediator between employees' perceptions of individual human resource management practices and talent turnover intention. However, the results contradict the hypothesis that self-efficacy moderates the association between work engagement and talent turnover intention.

This study focuses on the impact of perceived human resource management practices on talent turnover intention, an area that has received limited attention in literature. By focusing on perceived human resource management practices, this study illuminates employees' subjective experiences and how they perceive human resource management practices intended to reduce talent turnover intention. The inclusion of the mediating effect of work engagement offers a more profound understanding of how employees' perceptions of human resource management practices influence their turnover intentions. This comprehensive approach to understanding the interplay between these variables provides valuable insights for organizations seeking to improve their human resource management practices and talent turnover intention.

The case was devised using secondary sources of data collection from annual reports, sustainability reports and the Hindustan Petroleum Corporation Limited (HPCL) website. These documents provided insights into the HPCL’s sustainability initiatives, financial performance and disclosure practices. Other data were obtained through the websites of the relevant businesses/sectors.

In March 2022, Pushp Kumar Joshi, chairman and managing director of HPCL, contemplates the oil giant’s sustainability strategy amid challenges. Despite a 38% revenue increase in financial year 2021–2022, profits dropped because of reduced refinery capacity. HPCL, a major player in India’s oil and gas industry, recognized the need to align with climate goals and changing consumer expectations. Joshi emphasized stakeholder engagement, carbon mitigation, technology adoption and transparent environmental, social and governance (ESG) reporting. A materiality assessment highlighted key issues like gender diversity, air quality and the low-carbon transition. Joshi grapples with balancing profitability and sustainability amid stakeholder pressure and market fluctuations, seeking advice from the sustainability team for the future.

This can potentially be a case study for a business management course, particularly focusing on sustainability, corporate social responsibility and strategic decision-making. It could be used at both the undergraduate and graduate levels in courses related to business administration, sustainability management, corporate strategy, environmental management or stakeholder engagement. The case could be analyzed to discuss the challenges and opportunities faced by a company like HPCL in balancing profitability and sustainability, developing effective sustainability strategies, integrating ESG considerations and managing stakeholder expectations.

The expected learning outcomes are to understand the complexities involved in the integration of two carriers with different business strategies and approaches, the merger of two brands with distinct personas and identities and the confluence of two different cultures; figure out the strategic options in front of the Tata Group and how it can deal with various macro- and micro-level business challenges, defy the financial hiccups and manoeuvre the operational complexities to accomplish mission Vihaan.AI; and develop a pragmatic approach to macro and micro business environmental scanning for making strategic business decisions.

In November 2022, Tata Group, the salt to software conglomerate, announced the merger of Air India (AI) and Vistara. This would lead to the formation of the full-service airline under the brand name “Air India”. The obvious reason behind this was the higher recognition, salience and recall of the brand AI as compared with Vistara in the global market. The Tata Group envisaged the brand AI to be a significant international aviation player with the heritage, persona and ethos of the brand Vistara in the renewed manifestation of AI. To realise these goals, Tata Group laid down an ambitious plan called “Vihaan.AI”, which was aimed at capturing a domestic market share of 30% by 2027.

This case study can be taught as part of undergraduate- and postgraduate-level management programmes.
