This study aims to investigate the effects and implications of overconfidence in a competitive game involving multiple newsvendors. This study explores how overconfidence influences system coordination, optimal stocking strategies and competition among newsvendors in the context of the well-known newsvendor stocking problem.

The study applies robust optimization theory and the absolute regret minimization criterion to analyze the competitive game of overconfident newsvendors. This study considers the asymmetric information held by newsvendors regarding market demand and obtains a closed-form solution for the competing game. The effects of overconfidence on system coordination and optimal stocking strategies are examined.

The results of the study indicate that overconfidence can act as a positive force in reducing the effects of overstocking caused by competition and asymmetric information among newsvendors. The analysis reveals that there exists an optimal level of overconfidence that coordinates the ordering system of multiple overconfident newsvendors, leading to first-best outcomes under certain conditions. Additionally, numerical examples confirm the obtained results. Furthermore, considering newsvendors' expected profit, the study finds that a higher degree of overconfidence does not necessarily result in lower actual expected profit.

Despite the significant contributions of this study to theoretical and managerial insights, this study does have certain limitations. First, in the establishment of the belief demand function, the substitution ratio, which quantifies the transfer, is assumed to be an exogenous variable. However, in reality, this is often influenced by factors such as the price of goods and the distance between stores. Therefore, one direction worth studying in the future is to explore the uncertainty associated with the demand substitution ratio and integrate that as an endogenous variable into the optimization model. Second, this study does not address the type of product and solely focuses on quantitatively analyzing the effect of salvage value on the optimal stocking strategy. Future studies can explore the effect of degree of perishability and selling period of the product on the stocking. Third, the focus of uncertainty in this study revolves around market demand, and the implications of this uncertainty are significant. A recent study (Rahbari et al., 2023) addressed an innovative robust optimization problem related to canned foods during pandemic crises. The recent study's findings highlighted the effectiveness of expanding canned food exports to neighboring countries with economic justification as the best strategy for companies amidst the disruptions caused by the coronavirus disease 2019 (COVID-19) pandemic. Incorporating the issue of disruptions into the authors' research would be interesting and challenging.

From a managerial perspective, the authors' study provides a research paradigm for game-theoretic inventory problems in scenarios where the market demand distribution is unknown. While most inventory problems are analyzed and solved based on expectation-based optimization criteria, which rely on an accurate distribution of market demand, obtaining this information in practice can often be challenging or expensive for decision-makers. Consequently, a discrepancy arises between real-world observations and theoretical identifications. This study aimed to complement previous research and address the inconsistency between observations and theoretical identification.

The authors' research contributes to the existing understanding of overconfidence and assists individuals in making appropriate stocking strategies based on the individuals' level of overconfidence. Diverging significantly from the traditional view of overconfidence as a negative bias, the authors' results show the view's potential positive impact within a competitive environment, resulting in greater actual expected profits for newsvendors.

This study contributes to the existing literature by examining the effects of overconfidence in a competitive game of newsvendors. This study extends the analysis of the well-known newsvendor stocking problem by incorporating overconfidence and considering the implications for system coordination and competition. The application of robust optimization theory and the absolute regret minimization criterion provides a novel approach to studying overconfidence in this context.

This study aims to investigate the relationship between feminine gender identity and leadership intention. Based on the theory of planned behavior and social role theory, the indirect relationship between feminine gender identity and leadership intention was analyzed through affective motivation to lead and perceived leadership self-efficacy. In addition, drawing on the person–environment fit theory, feminine gender identity was examined as a moderator of the relationship between cooperative organizational culture and leadership intention.

A cross-sectional survey was administered among a sample of 183 full-time employees.

Results demonstrated that controlling for sex, perceived leadership self-efficacy mediated the relationship between feminine gender role identity and leadership intention. In addition, feminine gender role identity acted as a moderator in strengthening the relationship between cooperative organizational culture and leadership intention such that highly feminine individuals in high cooperative organizational cultures showed higher intentions to become leaders than did individuals with less feminine identities.

In research on leadership intentions, it will be important to measure both sex and gender, as gender identity explains variance in important outcomes over and above sex. In addition, beginning to include organizational characteristics (such as perception of culture) in this stream of research is important.

Organizations wishing to promote more feminine individuals to leadership roles should examine their organizational culture to determine if it is cooperative, as this type of culture allows these individuals to be more intent on seeking leadership roles.

This research adds up to the literature by looking at an organizational factor, culture, and analyzing its role in increasing leadership intention in highly feminine individuals. In addition, by studying gender while controlling for sex, this paper suggests that regardless of sex (being a female or a male), feminine individuals will benefit from a cooperative environment. This includes any individuals (females and males) that identify more with communal behaviors.

The purpose of this study is to examine the politics, political economy, and fallout of hawkish regulatory policy on prescription drugs in Nigeria. Hawkish regulatory policy on prescription drug in Nigeria, such as opioid analgesics, is a very complex and multifaceted one, which usually involves the interplay of many factors and parties.

Policy manuals, official government gazettes (legislations, regulations, Acts and decrees), academic literature and a direct ethnographic observation of events surrounding the regulation of prescription drugs were reviewed and engaged.

The results revealed that Nigerian and global political economy and politics interface to define the direction of the new restrictive opioid policy, with resultant friction between prohibition and consumption. The reviews showed that the overarching “get-tough” and “repressive” policy are not necessarily founded on empirical evidence of an increase in prescription drug sales or use, but more as a product of the interplay of both internal and external politics and the prevailing socioeconomic order.

Instead of borrowing extensively from or being influenced by repressive Western drug laws and perspectives, Nigerian policymakers on prescription opioids should take control of the process by drawing up a home-grown policy that is less intrusive and punitive in nature for better outcomes. A mental sea change is required to understand the intrigues of Western power in Nigeria’s politics and political economy to avoid the continuous symptomatic failure of drug policy.

The politics and economic influence of the United Nations, USA and Western powers, as well as the axiom of moral panic of prescription drugs scares within the Nigerian environment, are particularly significant in the making of the emerging hawkish policy on prescription drugs in Nigeria.

The purpose of the paper is to construct a model that considers video purchase and then identifies the logical relationships implied by the parameters to explore video platform operation mechanisms.

The authors analyzed the video platform system using a mathematical modeling approach and numerical optimization techniques. Through pricing decisions, the authors obtained equilibrium results for the profitability of the video platforms and analyzed the favorable market factors. The authors then extended the model by analyzing the competitive strategies of the two video platforms in the market.

The authors find that advertiser profitability, ad nuisance, video sensitivity and video creator network effects are important factors influencing the pricing strategy of video platforms. During positive market conditions, video platforms tend to lower their prices until they absorb enough users. As market conditions change, the price adjustment strategies of video platforms are affected by parameter changes and inter-parameter relationships.

The study considers the network effects of video creators, which provides a realistic reference for scholars and managers. In addition, the authors consider the bargaining power of platforms when purchasing content. The authors provide a fresh perspective for scholars while filling a gap in the field as video platforms can acquire a portion of the content on the market by setting a purchase price.

The paper proposes a two-level closed-loop supply chain (CLSC) dynamic competitive model based on different competitive cooperation situations, and explores the impact of competitive cooperation methods on the pricing strategies, recycling and remanufacturing strategies and competitive model selection strategies of supply chain firms.

This paper establishes a CLSC game consisting of a manufacturer and two retailers. Firstly, five CLSC models are established in both horizontal and vertical dimensions, each of which competes with one another. Secondly, the recycling and remanufacturing pricing strategies are analyzed under different competition or cooperation models. Finally, the results are verified through numerical analysis.

The overall profitability of the CLSC is highest when the manufacturer–retailer partnership alliance is in place. The relationship between retailers and manufacturers is also found to be the best way to achieve overall optimization of the CLSC.

The paper investigates the relationship between the competitive partnership and the total profit of the CLSC, taking into account how to optimize the overall benefit, and focusing on how to optimize the individual interests of each participating enterprise. The results can provide basis and guidance for managers' pricing decision and competition cooperation.

By adopting a cultural lens, this study aims to conceptualize destination-community hospitality to capture societal hospitality at the destination as an intangible asset. Destination-community hospitality comprises a set of attitudes and traits that are organically conveyed by community members and directly experienced by tourists. The paper contributes to efforts aimed at freeing hospitality from the confines of commercial lodging and food and beverage establishments.

This study proposes an affection–attention–awareness (AAA) framework by drawing on the pertinent literature and leveraging the affective–behavioral–cognitive model of attitudinal change. It focuses on the effects of cognition in conceptualizing destination-community hospitality as the core of the framework. Methodologically, the framework is illustrated with qualitative data including observational fieldwork and interviews conducted in Iran.

Illustration of the AAA framework in the context of Iran highlights how welcoming attitudes are leveraged at a destination as an ingrained community mindset even in the absence of formal initiatives or professional training. It underscores the hospitality advocacy role of local-community members irrespective of public-sector policy and capacity deficiencies.

Destinations that strive to attract tourists should tap into the significant wealth of intuitive hospitality within communities as an intangible resource. The ingenuity should be preserved to sustainably enhance the overall tourist experiences. The framework can serve as a guide to strategically facilitate destination-community hospitality.

Research on community-wide hospitality at destinations, as a major cultural asset in the context of strategic hospitality management, remains underdeveloped. With illustrative evidence, the findings elevate the critical role of community members as innate advocates of hospitality in developing destinations. The proposed framework of destination-community hospitality provides a new perspective and impetus for investigating hospitality beyond commercial domains.

Users' knowledge contribution behaviors are critical for online Q&A communities to thrive. Well-organized question threads in online Q&A communities enable users to clearly read existing answers and their evaluations before contributing. Based on the social comparison and peer influence literature, the authors examine peer influence on the informativeness of knowledge contributions in competitive settings. The authors also consider three levels of moderating factors concerning individuals' perception of competitiveness: question level, thread level and contributor level.

The authors collected data from one of the largest online Q&A communities in China. The hypotheses were validated using hierarchical linear models with cross-classified random effects. The generalized propensity score weighting method was employed for the robustness check.

The authors demonstrate the peer influence due to social comparison concerns among knowledge contribution behaviors in the same question thread. If more prior knowledge contributors choose to contribute long answers in the question thread, the subsequent contributions are more informative. This peer influence is stronger for factual questions and questions with higher popularity of answering but weaker in recommendation-type and well-answered questions and for contributors with higher social status.

This research provides a new cue of peer influence on online UGC contributions in competitive settings initiated by social comparison concerns. Additionally, the authors identify three levels of moderating factors (question level, thread level and contributor level) that are specific to online Q&A settings and are related to a contributor's perception of competitiveness, which affect the direct effect of peer influence on knowledge contributions. Rather than focus on motivation and quality evaluation, the authors concentrate on the specific content of online knowledge contributions. Peer influence here is not based on an actual acquaintance or a following relationship but on answering the same question. The authors also illustrate the competitive peer influence in subjective and personalized behaviors in online UGC communities.

This study aims to examine the role of safety governance in ensuring public–private interface ecosystems in response to the COVID-19 pandemic. It aims to highlight the role of safety governance in the complex interfaces of pandemic response mechanisms. The analysis is conducted at the national level, considering safety governance issues in terms of test, confirmed cases, fatality rates, vaccination rate, medical capabilities, Information and communications technology capability, Hofstede’s cultural index (individualism and power distance scores), public safety, personal privacy and national health capabilities.

Using multigovernance theory and technology, organization and environment theory, the authors present a research model that defines four independent factors and country level performance outcomes and conducted analysis of variance tests.

Research findings suggest that countries are classified by diverse groups using multiple criteria (e.g. country size, Hofstede’s cultural indexes, ICT capabilities and Governance index). Countries indicate differences in their policy approaches according to their private and public ecosystems. COVID-19 response performance indicators are substantially different.

This study provides the relevance of the multigovernance theory. The empirical results suggest that effective crisis governance is characterized by vertically integrated organizational hierarchies with horizontally connected communication channels that seek maximum voluntary participation and a high level of motivation of informed societal members as a whole. Crisis events occur occasionally, and livelihood routines demonstrate incredible human agility. Gaining insight of the findings from this article may be useful to respond to future crisis events.

This significant study highlights the political and social factors that define response patterns of different countries regarding COVID-19 response mechanisms. With the wide vaccination administration, the COVID-19 landscape shows differences in these countries. This study is rare in providing research framework using Hofstede cultural value and examines with actual data provided by each national government, World Health Organization and credible information sources.

This chapter makes a case for extending institutional preservation strategies to the entire landscape of knowledge capital. First, the authors define the three primary types of capital – physical, financial, and knowledge. Knowledge capital is further broken down into three categories – human, structural, and relational. The individual types of knowledge capital are defined, along with their variant economic properties and behaviors. The challenges these variations present for preservation are discussed. The authors also highlight these assets’ significant opportunities for curating new knowledge. Each type of knowledge capital is described, along with the preservation challenges and the curation opportunities.

Starting with the notion that each building has an overall life cycle, the paper uses building-based and investment-based life cycles to identify likely decision points for renovations, including sustainability enhancements, and identifies patterns in sustainability decisions.

This real estate insights paper considers how commercial real estate and the built environment it creates, owns and manages impacts the sustainability of urban areas and the globe. By combining building-based and investment-based life cycles, it is possible to develop a unique “sustainability enhancement quotient” for individual buildings and the built environment for an urban area over a given time interval.

Using two life cycles allows the identification and likelihood of sustainability decision points. The same life cycles and decision points are used to consider the likely extent of such renovations. This is in addition to continuous consideration of renovations producing economic benefits in the form of lower operating costs and quick return of capital.

Useful for investment decision-making and policy design and implementation.

This is a useful tool for public and private decision making. It is suggested that the sustainability enhancement quotient may be used to design and implement policies and decisions maximising the likelihood of sustainability enhancement in an urban area's built environment.

Provides a framework for more effective sustainability decisions and public policy. The public-private interplay inherent in every building is emphasised throughout.
