Monetary policy and food price inflation: the case of Hungary
Authors: Bareith Tibor , Fertő Imre 
Published: May 2024

PurposeWe analyze the role of monetary policy shocks on food inflation in Hungary from January 2007 to March 2023, including the period of the COVID-19 crisis and the Russo–Ukrainian war.Design/methodology/approachWe use quantile regression with three different specifications. The structural breaks in the time series and the monetary policy’s lag in response are also taken into account. We use the M0 money supply and the three-month Hungarian National Bank (MNB) deposit rate as monetary measures to check the robustness of our findings.FindingsWe find that neither the money supply nor the exchange rate affected food inflation across quantiles. In the case of high food price inflation, reducing short-term government bond yields may be an effective solution. Household final consumption affected food prices in the lower quantiles, and the global food price index similarly affected Hungarian food inflation. The results are robust to different specifications.Research limitations/implicationsThis research has limitations as follows: while Hungary’s food prices provide a valuable case study, expanding to more countries is advisable; although quantile regression captures details, its reliability for non-linear relationships is questionable; additionally, considering various global food price indicators can enhance result robustness.Originality/valueThe paper contributes to the longstanding political debate regarding the effectiveness of monetary policy in stabilizing food inflation. The findings emphasize the importance of considering both domestic and global factors in formulating policy responses to food price dynamics.
The role of Covid-19 policy responses on GVC participation: the Turkish experience
Authors: Altun Abdullah , Tat Pınar , Yanikkaya Halit 
Published: May 2024

PurposeThis paper explores the association between a variety of trade and government policy measures of both home and trade partners introduced during the Covid-19 pandemic within the gravity-like framework by using the Turkish bilateral trade statistics at the six-digit product level from February 2020 to March 2022.Design/methodology/approachThe empirical model is estimated by employing the two-way fixed effects (TWFE) estimation technique to get rid of the effects of unobserved time-invariant idiosyncratic country-product effects in the model and to evade the possible autocorrelation problem of trade measures.FindingsOur empirical analysis suggests that lower Turkish GVC participation during this period can be attributed to lower mobilities and the lack of vaccines globally. Our analysis utilizing the different income groups of countries and technology group of sectors suggests that Turkish high-tech backward participation with developed countries can be more sensitive to any changes in Covid-19-related policy measures, whereas Turkish forward participation with both developed and developing markets can be more volatile during the pandemic because of the containment measures.Practical implicationsSustaining mobility in the global production process is the key finding to sustain both backward and forward GVC linkages. In addition, enhancing a variety of partner countries is crucial for sustaining the flows of imported intermediates of the Turkish manufacturing sectors. Moreover, the sophistication of Turkish exported products can be the solution to continue the forward GVC participation even in the shock times. Given the product and partner country-level heterogeneities regarding contingency measures implemented by the governments, policymakers should carefully monitor each sub-sample separately and focus especially on enhancement in information, communication and transportation infrastructures to mitigate the contagious effect of any external shocks.Originality/valueThe unique monthly six-digit bilateral product-level trade dataset enables us to observe and utilize heterogeneous effects at the product, sector and partner country levels.
The asymmetric impact of monetary policy and firm leverage on firm investment: some insights from Pakistan
Authors: Ahmad Farooq , Rashid Abdul , Shah Anwar 
Published: May 2024

Purpose
This paper aims to investigate whether negative and positive monetary policy (MP) shocks have asymmetric impacts on corporate firms’ investment decisions in Pakistan using firm-level panel data set. Moreover, the authors emphasized on symmetric effects of MP; the authors examine whether high-leverage and low-leverage firms respond differently to negative and positive unanticipated shocks in MP instruments.

Design/methodology/approach
In contrast to the conventional framework of VAR, it uses an alternative methodology of Taylor rule to estimate unanticipated MP shocks. The two-step system-generalized method of movement (GMM) estimation method is applied to examine the effect of MP shocks on firm investment through leverage-based asymmetry.

Findings
The two-step system-GMM estimation results indicate that unanticipated negative changes (unfavorable shocks) in MP instruments have negative, significant effects on investment. In contrast, unanticipated positive changes (favorable shocks) have statistically insignificant impacts on firm investment. The results also reveal that firm leverage has a significant role in establishing the effect of unanticipated negative changes in MP instruments on investments. Finally, the results indicate that high-leverage firms respond more to negative changes than low-leverage firms. Yet, the results show that only low-leverage firms positively respond to unanticipated positive shocks in MP.

Practical implications
The findings of the paper suggest that MP authorities should pay due attention to the asymmetric effects of MP shocks on firm investment while designing MP. Because firm leverage has a significant influence on the effects of MP shocks, firm managers should take into account such role of leverage while deciding capital structure of their firms.

Originality/value
First, unlike “Keynesian asymmetry” and most of published empirical research work, the authors use both unanticipated negative and positive MP shocks simultaneously. Departing from the conventional empirical literature, the authors differentiate between unanticipated positive and negative shocks in MP using the backward-looking Taylor rule. Second, the authors contribute to the existing literature by investigating the differential effects of positive and negative unanticipated MP shocks on firms’ investment decisions. Unlike the published studies that have emphasized on the symmetric effects of MP, the authors examine whether high-leverage and low-leverage firms respond differently to negative and positive unanticipated shocks in MP instruments.
Assessing Bitcoin, gold and gold-backed cryptocurrencies as safe havens for energy and agricultural commodities: insights from COVID-19, Russia–Ukraine conflict and SVB collapse
Authors: Snene Manzli Yasmine , Jeribi Ahmed 
Published: May 2024

Purpose
This paper aims to investigate the safe haven feature of Bitcoin, gold and two gold-backed cryptocurrencies (DGX and PAXG) against energy and agricultural commodities (crude oil, natural gas and wheat) during the COVID-19 pandemic, the Russia–Ukraine conflict and the Silicon Valley Bank (SVB) collapse.

Design/methodology/approach
The authors use the threshold GARCH (T-GARCH)-asymmetric dynamic conditional correlation (ADCC) model to evaluate the asymmetric dynamic conditional correlation between the return series and compare the diversifying, hedging and safe-haven ability of Bitcoin, gold and the two gold-backed cryptocurrencies (DGX and PAXG) against financial swings in the commodity market during the COVID-19 outbreak, the Russian–Ukrainian military conflict and SVB collapse. The authors also calculate the hedging ratios (HR) and hedging effectiveness index (HE). The authors finally use the wavelet coherence (WC) approach to check our results’ robustness and further investigate the impact of the three crises on the relationship between Bitcoin, gold gold-backed cryptocurrencies and commodities.

Findings
The results show that PAXG serves as a strong hedging instrument while gold, Bitcoin and DGX act as strong diversifiers during normal times. During crises, gold outperforms Bitcoin as a diversifier and a safe haven against commodities. Gold-backed cryptocurrencies also exhibit strong performance as diversifiers and safe havens. HR results indicate that Bitcoin and DGX are more cost-effective for commodities risk mitigation than gold and PAXG. In terms of hedging effectiveness, gold and PAXG emerge as the best hedging instruments for commodities, while DGX is considered the worst one. Bitcoin shows superior hedging against oil compared to wheat and gas risks. Moreover, the results of the WC approach confirm those of the T-GARCH-ADCC results in both the short and long run.

Originality/value
This paper provides a comprehensive analysis of the diversification ability of gold, Bitcoin and gold-backed cryptocurrencies during different crises (the COVID-19 pandemic, the Russia–Ukraine conflict and the SVB collapse). By taking into consideration gold-backed cryptocurrencies, the authors expand the understanding of safe havens beyond conventional assets.
Brand loyalty model for halal fashion brands: integrating quality-loyalty model, information sources and religiosity-loyalty model
Authors: Rafdinal Wahyu , Setiawardani Maya , Raharso Sri , Hardiyanto Nugroho 
Published: May 2024

Purpose
The purpose of this study is to investigate brand loyalty in halal fashion brands through three loyalty routes, namely, quality-satisfaction-loyalty model, information sources and religiosity-loyalty model.

Design/methodology/approach
Data were gathered from 447 customers of halal fashion brands through a survey. The structural equation model partial least square was used to validate the hypotheses empirically.

Findings
From the perspective of customers in halal fashion, brand loyalty is primarily determined by brand satisfaction, which is influenced by the perceived quality, firm-generated content (FGC) and user-generated content (UGC). While religiosity contributes significantly to brand loyalty, it has no direct impact on brand satisfaction. Perceived quality and information obtained through both FGC and UGC channels have a significant effect on brand satisfaction. Finally, perceived quality, FGC, UGC, religiosity and brand satisfaction play important roles in promoting brand loyalty among halal fashion customers.

Research limitations/implications
This study will assist halal fashion companies in evaluating perceived quality, information sources (FGC and UGC) and religiosity to increase brand satisfaction and brand loyalty. This study expands to the existing knowledge about brand marketing literature on halal fashion brands.

Originality/value
This study is a preliminary empirical study that explains the three routes of brand loyalty through the quality-satisfaction-loyalty model, information sources and religiosity-loyalty model in the context of halal fashion brands. This study also provides insights for marketers and business managers to enhance brand loyalty in halal fashion brands.
How transformational leadership shapes employee task performance? A sequential mediation model
Authors: Vila-Vázquez Guadalupe , Castro-Casal Carmen , García-Chas Romina , Álvarez-Pérez Dolores 
Published: May 2024

PurposeThe purpose of this study was to analyze, through a sequential model, the underlying mechanisms connecting transformational leadership with employee task performance. Specifically, it examined the causal chain of transformational leadership-job characteristics (task variety and task significance)-job engagement-task performance.Design/methodology/approachThe hypotheses were tested on a sample of 320 employees and their supervisors from Spanish young technology and knowledge-intensive small and medium-sized enterprises (SMEs) using structural equations.FindingsThe results show that the effect of transformational leadership on task performance (assessed by supervisors) occurs sequentially via task significance and job engagement. Additionally, job engagement mediates the relationship between task variety and task performance.Practical implicationsFindings highlight the relevance for supervisors to employ a transformational leadership style that leads employees directly and indirectly, through task significance, to be more engaged and achieve higher task performance. They also emphasize the importance of proper job design that allows employees to be fully invested in their job performance.Originality/valueDespite the importance of leadership and employee performance for the survival and growth of these firms, the study of these relationships is largely unexplored. This study proposes and tests a serial model in which supervisor transformational leadership is linked to employee task performance through two sequential mediators: job characteristics (task variety and task significance) and job engagement.
Unveiling the path to employee performance excellence: visionary leadership behavior, vision commitment and organization resource support
Authors: Yang De-Long , Yang Ning 
Published: May 2024

PurposeDrawing on goal setting theory (GST), this study explores the relationship between visionary leadership behavior (VLB) and employee performance, along with the mediating role of vision commitment and the moderating role of organization resource support.Design/methodology/approachWe conducted two studies to test hypotheses. Study 1 and Study 2 collected data from 212 and 204 full-time employees and their leaders, respectively. The data were analyzed using hierarchical regression and bootstrapping technique.FindingsWe found that VLB is positively related to employee vision commitment and vision commitment mediates the effect of VLB on employee performance. Organization resource support moderates the effect of vision commitment on employee performance and the indirect effect of VLB on employee performance via vision commitment, such that the two effects are stronger when organization resource support is high.Originality/valueFirst, this study reveals the mediating role of vision commitment in the relationships between VLB and employee performance. Second, this study explores the moderating role of organization resource support in the relationship between VLB and employee performance. Third, this study enriches the theoretical perspective of VLB research and expands the application scope of GST.
Paradoxical leadership and employee creativity: the roles of harmonious work passion and proactive personality
Authors: Lin Chen , Zhou Xiaohu , Hou De'en 
Published: May 2024

PurposeThe process of fostering and enhancing employee creativity (EC) is multifaceted and involves various challenges and contradictions, with paradoxical leadership (PL) playing a crucial role. However, previous research has neglected the importance of employee emotions, resulting in an incomplete understanding of the underlying mechanisms. To address this gap, this study draws upon the triadic reciprocal determinism of social cognitive theory to construct a moderated mediation model. The objective is to investigate the mediating role of harmonious work passion (HP) in the relationship between PL and EC. Furthermore, the study aims to explore the moderating effect of proactive personality (PP).Design/methodology/approachTwo surveys were carried out in eight enterprises situated in China. A total of 337 employees took part in the questionnaire survey to explore the correlation between PL, PP and HP. Additionally, 42 supervisors participated in evaluating the creativity of their subordinates. To test the proposed hypotheses, this study utilized hierarchical regression analysis on a sample of supervisor-subordinate pairs.FindingsParadoxical leadership is positively correlated with employee harmonious work passion. Harmonious work passion is positively correlated with employee creativity. Harmonious work passion plays a mediating role between paradoxical leadership and employee creativity. Proactive personality moderates the relationship between paradoxical leadership and harmonious work passion. Proactive personality moderates the indirect effect of harmonious work passion on the relationship between paradoxical leadership and employee creativity.Practical implicationsThe results of this study provide practical suggestions for improving EC. For example, organizations can select supervisors who exhibit PL qualities and enhance the training programs for leaders in the domain of paradoxical thinking. Furthermore, it is crucial for leaders to prioritize the development of employees' HP and to be attentive to the distinct individual variations present within their workforce.Originality/valueThis study enriches the research on the mediating and moderating mechanism between PL and EC and opens the black box from the perspective of emotion. Moreover, this research examines the boundary condition under which PL functions. The study reveals the interaction of environment, personality, cognition and emotion on creativity and provides a new perspective and empirical support for future research.

Published: May 2024

Purpose
The purpose of this paper is to meet Dr Claude-Hélène Mayer, Professor in Industrial and Organisational Psychology at the University of Johannesburg, Johannesburg, South Africa.

Design/methodology/approach
This is a qualitative positive autoethnographic case study. Mayer uses positive autoethnography to reflect on mental health, positive psychology and leadership across the life span. The first author also responds to ten questions.

Findings
Leadership can be developed and appreciated in others. Leadership can be a positive and transformative force that can assist and contribute to mental health and well-being. Positive leadership can be supported by developing wisdom, creativity, critical thinking and conflict and emotional management.

Research limitations/implications
Qualitative research cannot be generalised. Positive autoethnography reflects the views and experiences of the author, in this case a transdisciplinary and transcultural researcher and practitioner.

Practical implications
Readers will find a range of practical recommendations as to how to develop mental health and leadership and stay positive in challenging times. Academic literature relating to practical recommendations is also shared.

Social implications
Positive leadership has many social implications. It can be a constructive influence that impacts our lives and benefits our personal development, but also one that impacts the lives and benefits the personal development of other people.

Originality/value
In this original paper, Dr Claude-Hélène Mayer shares mental health, positive psychology and leadership experiences and recommendations. Leadership skills are of particular value in times of complex change.
Exploring the psychological and emotional burden of compulsory acquisition: a case study of New Akrade-Mpakadan, Ghana
Authors: Ewusie Isaac , Tannor Oliver , Ahiadu Albert Agbeko , Ntim Olivia Kwakyewaa 
Published: May 2024

PurposeThis paper aims to explore the psychological, emotional and equity implications of compulsory acquisition, evaluate the adequacy of compensation in mitigating those consequences and assess the sustainability of cash compensation for future generations.Design/methodology/approachA case study approach was operationalised to investigate the experiences of 40 project-affected persons (PAPs) four years after a compulsory acquisition project in Ghana’s New Akrade-Mpakadan region for the construction of a railway line. These perspectives were analysed through descriptive statistics and thematic analyses using the NVivo software. Figures and a holistic framework were adopted to report the identified issues.FindingsOverall, only 25% of PAPs received formal communication prior to the acquisition, and only 10.3% have been fully compensated four years later. Despite the acquiring body initiating the marking of properties and compensation assessment in 2019, no payments were made until 2021. This induced emotional responses of distress, loss, uncertainty, stress and sadness, which was further exacerbated by feelings of hopelessness because there was no platform to voice concerns or pursue arbitration. Although PAPs were only offered compensation in the form of single monetary payments, a third would have preferred re-settlement.Research limitations/implicationsBy exploring the emotional and psychological effects of compulsory land acquisition, the study adds a new dimension to understanding its consequences. This may spark more interest, debate and discourse amongst researchers and policymakers and lead to the creation or enhancement of existing policy and legal measures to address the needs of PAPs in compulsory acquisition projects in developing countries.Originality/valueThe financial consequences of eminent domain are well documented, but this study explored the psychological, emotional and equity implications of the practice under conditions of weak regulatory frameworks. The adequacy of single lump-sum compensations was also explored to highlight preferred alternatives to ensure fairness for generations unborn.
