This study aims to investigate the impact of market competitiveness on investment efficiency, and the moderating role of ownership and regulatory structures.

In this study, the Herfindahl–Hirschman Index (HHI), Lerner Index (LI) and industry-adjusted Lerner Index (LIIA) were used to measure market competitiveness. The research population consisted of companies listed on Tehran Stock Exchange (TSE). Using a systematic elimination, 199 companies were selected within eight years during 2014–2021.

The results showed that market competitiveness (based on the LI, LIIA and HHI) positively affected investment efficiency. Moreover, institutional ownership and managerial ownership affected the relationship between market competitiveness (based on all proxies of market competitiveness) and investment efficiency. Blockholders’ ownership also moderated the relationship between market competitiveness (based on LIIA and HHI) and investment efficiency. The hypothesis testing had robustness based on additional analyses.

In recent years, competitive environment and the ownership structure of companies have changed to a certain degree, paving the way for the private sector to enter many areas of activity especially in emerging Asian markets. Moreover, investment drivers and investment efficiency in developed markets may not be generalized to emerging Asian markets. Therefore, the present findings can show the significance of this research to fill the existing gap in the literature and provide insights into ownership and regulatory structures as a governance mechanism in market competitiveness and investment efficiency.

Pay-what-you-want (PWYW) is a pricing strategy implemented in a variety of settings like supermarkets and museums, in which consumers determine the price they are willing to pay for a product or service based on their perceived utility. The authors propose an analytical model to investigate the impact of PWYW delivery pricing on the online food delivery (OFD) platforms.

Using a game-theoretic model, the authors characterize the equilibrium as a function of the platform's average delivery cost and the consumer's social preferences parameters like fairness and reciprocity. The authors derive the parametric conditions under which PWYW generates higher profits for the platform compared to the traditional pay-as-asked delivery pricing.

For the PWYW strategy to be profitable, the average delivery cost to the platform should be low. Therefore, OFD platform managers should focus on reducing delivery costs. The authors also identify the feasible region in which the platform managers need to maintain the consumer's social preferences.

Under PWYW, the authors recommend that the platform managers impose a minimum delivery fee which consumers can use as a benchmark to minimize zero delivery fee payments and consumers' free-riding tendencies simultaneously. This allows OFD platforms to extract online orders from highly price-conscious consumers.

This is one of the first studies to explore the innovative application of PWYW to a particular segment of delivery pricing in OFD platforms. The authors establish that the overall consumer surplus and social welfare are higher under the PWYW strategy, forming a solid ground for its implementation in OFD platforms.

Online food delivery (OFD) has witnessed momentous consumer adoption in the past few years, and COVID-19, if anything, is only accelerating its growth. This paper captures numerous intricate issues arising from the complex relationship among the stakeholders because of the enhanced scale of the OFD business. The purpose of this paper is to highlight publication trends in OFD and identify potential future research themes.

The authors conducted a tri-method study – systematic literature review, bibliometric and thematic content analysis – of 43 articles on OFD published in 24 journals from 2015 to 2021 (March). The authors used VOSviewer to perform citation analysis.

Systematic literature review of the existing OFD research resulted in six potential research themes. Further, thematic content analysis synthesized and categorized the literature into four knowledge clusters, namely, (i) digital mediation in OFD, (ii) dynamic OFD operations, (iii) OFD adoption by consumers and (iv) risk and trust issues in OFD. The authors also present the emerging trends in terms of the most influential articles, authors and journals.

This paper captures the different facets of interactions among various OFD stakeholders and highlights the intricate issues and challenges that require immediate attention from researchers and practitioners.

This is one of the few studies to synthesize OFD literature that sheds light on unexplored aspects of complex relationships among OFD stakeholders through four clusters and six research themes through a conceptual framework.

This study is set out to assess the country of origin effect on Turkish consumption practices in order to provide a richer context for its formation process.

The research is exploratory and interpretative in nature. It follows a qualitative design with in-depth analysis of consumption experiences by utilizing semi-structured interviews.

The research shows that country of origin effect is product specific, and when it exists, it has an essential effect on product evaluations. It reveals that the country of origin effect is intrinsically constituted with the individual perceptions of and attitudes toward brands, countries, and past experiences, and it is extrinsically constituted with socially created perceptions by media, marketplace myths, and popularity.

This research investigated country of origin effect in a specific context of a developing country with a qualitative methodology. Unlike the existing literature, this study analyzes consumers’ actual purchase decisions in different product categories. Country of origin effect is found to be formed by individual and societal factors.

This study aims to explore how shared values improve eudaimonic workplace well-being, the fulfillment that comes from personal development and the utilization of personal capabilities. The authors investigate the serial mediating role that perceived overall justice and emotional exhaustion play in how shared values relate to well-being.

Using data collected from three hundred nurses in Turkish healthcare institutions during the COVID-19 pandemic (Male = 113, Female = 187). The age of participants ranged from 19 to 58 and the average age was 34. The snowball sampling method was used to form the sample and self-administered surveys that could be completed online were delivered to the sampled nurses.

The authors analysis using partial least square structural equation modeling (PLS-SEM) supported the expected relationship between shared values and eudaimonic workplace well-being as well as the mediating role of perceived overall justice and emotional exhaustion. The authors also show a serial mediation where shared values are related to justice perceptions which in turn negatively relate to emotional exhaustion which subsequently relates to higher levels of eudaimonic workplace well-being.

The results of this study suggest that when the shared values between the healthcare institution and the employees are aligned, the eudaimonic well-being of employees is higher. The findings provide implications for the mental health of frontline employees in health organizations to have higher levels of eudaimonic well-being which is especially important in times of intense pressure such as the period during the COVID-19 pandemic.

This paper aims to investigate if product pre-announcement effects measured using stock market returns conform to the predictions of two competing consumer marketing theories. In particular, while buzz marketing theory indicates a direct positive effect, information asymmetry theory suggests an influence contingent upon evidence. The study also investigates whether a pecking order of performance effects exists across different signaling situations.

The final sample consists of 219 product-preannouncements reported in the Wall Street Journal between 2005 and 2015. The standard event study methodology was used to test for performance effects.

The results show that preannouncements with evidence alone significantly outperform those with buzz alone, and announcements containing buzz and evidence. Also, buzz acts as a salient moderator of the relationship between evidence and performance. In addition, company size also affects the evidence-performance relationship, with smaller firms benefiting more from evidence than larger firms.

The event study method assumes efficient markets and deals with publicly traded companies.

Managers can allocate resources wisely by deciding whether to invest in evidence or buzz in their pre-announcements.

In contrast to extant research that primarily investigates contingency effects, this study identifies how an important moderator, i.e. buzz affects performance.

Elements of national and organizational cultures can contribute much to the success of error management in organizations. Accordingly, this study aims to consider how errors were approached in two state university departments in Turkey in relation to their specific organizational and national cultures.

The study follows a qualitative case study design, and the data were collected through five focus groups. The cases under consideration were two state university departments of different organizational sizes.

The results showed that organizational and national culture elements (collectivism, high power distance and relatively low future orientation) significantly interacted with error management practices. In both of the organizations studied, there were found to be limited attempts to prevent the errors unless there was an emergent situation. Error detection was shown to be slow and hindered because of indirect communication among staff. Ultimately, effective error management in these organizations was identified as being unattainable because of negative emotional reactions to errors, lower reporting, restricted communication, potential face loss considerations and lack of feedback.

The findings of the current work extend earlier error management research with empirical data drawn from two cases in the higher education domain. Thus, the study offers preliminary research into the error process in education, and contributes to future research relating organizational culture to error processes.

Industry 4.0 accelerates the performance of supply chains, in particular, the reduction in supply chain cost (SCC) and improvement in supply chain flexibility (SCF). The aim of this study is to examine the role of Industry 4.0 on SCC and SCF, using network theory to explain the interrelationships.

Data were collected from 182 manufacturing firms in Turkey. The partial least square structural equation modelling (PLS-SEM) was employed in testing the research hypotheses.

The results showed that Industry 4.0 positively affects SCC; however, no direct relationship was found between Industry 4.0 and SCF. Moreover, SCC was found to have a positive impact on SCF, while SCC was found to mediate the relationship between Industry 4.0 and SCF. An additional finding was that customer integration (CI) moderates the relationship between Industry 4.0 and SCC; however, CI does not moderate the relationship between Industry 4.0 and SCF.

The research validates the role of Industry 4.0 on supply chain processes and thus provides valuable insights into supply chain practitioners and decision-makers interested in Industry 4.0 for supply chain management.

In view of the limited number of studies, this study empirically contributes to the literature on the relationships among Industry 4.0, SCC, SCF and CI.

The specific objective of the study is to investigate the presence of natural rate of crime rates in selected emerging economies by using panel unit roots. The majority of the literature examines the issue using conventional unit root tests in a country-specific context. Meanwhile, there is no panel unit root investigation has been undertaken considering both cross-sectional dependence (CD) and structural changes.

As a result, this study is to fill the aforementioned gap and validate the natural rate of crime rates for 10 countries by using a Fourier panel unit root test. The advantage of the test is that structural shifts are modelled as gradual or smooth changes with a Fourier approximation, and it also accounts cross-sectional dependency. Thus, the Fourier panel unit root test may have better performance in capturing potential changes in the nature of data.

The result of the conventional unit roots test shows evidence of the hysteresis effect in crime, as it stands does not adequately account for smooth transitions or breaks. On contrary, the Fourier panel unit root test confirms the natural rate hypothesis in crime rates. The present results highlight the detrimental effects of crime cannot be abated by short-run deterrence policies.

Contrary to previous studies, the theoretical implications of the study imply that the empirical models consider the dynamic nature of crime rates should account for natural rate properties instead of the hysteresis assumption.

Peer mentoring programs in higher education settings support incoming students in their transition and adaptation to college life. Mentoring program evaluation research primarily focuses on student outcomes and documents mentoring relationship quality (MRQ) as an important component of programs that facilitate change. The current study examines MRQ in a college peer mentoring program and explores its association with mentors’ and mentees’ perceptions of family relationships.

The sample included 629 first-year students (Mage = 18.4 and 54.2% female) and 88 mentors (Mage = 20.6 and 65.9% female). Each mentor was matched with eight to 10 incoming students in the same department. Dyadic data were collected prior to the program (pre-test) and at the end of the fall semester (mid-program) and spring semester (post-test). At pre-test assessment, mentors and mentees rated their family relationships, perceived trust, loyalty, and fairness in their families. At follow-up assessments, mentees reported their MRQ, mentoring duration, and mentoring activities.

A multilevel modeling analysis revealed that mentees’ and mentors’ perceptions of loyalty in their families predicted higher levels of MRQ at the end of the program. However, mentors’ perceived trust in their families was negatively associated with MRQ.

This study adds to the youth mentoring literature by focusing on family-of-origin experiences of both mentors and mentees from a dyadic and relational perspective. These findings have implications for future research and the practice of formal mentoring programs in college settings.
