Drawing on service-dominant logic and co-creation literature, this study explores how social media marketing activities (SMMAs) in online healthcare communities (OHCs) impact patients’ electronic word of mouth (E-WOM). Additionally, it aims to understand how patients’ E-WOM contributes to participation in value co-creation (PVCC) during the healthcare journey and influences patient well-being. This study also investigates the mediating role of patients’ E-WOM in bridging the relationship between the dimensions of SMMAs and patient PVCC dimensions.

Data were collected from 601 healthcare customers through a structured survey. Hypotheses were tested using partial least structural equation modeling (PLS-SEM) with SmartPLS 4.0.

Results demonstrate that interactivity and trendiness dimensions of SMMAs positively impact patients’ E-WOM communication. Patients’ E-WOM communication enhances their PVCC by influencing information seeking, information sharing, personal interaction and responsible behavior dimensions. Information seeking, personal interaction and responsible behavior in patient-provider interactions during the healthcare journey augment patients’ well-being, such as satisfying patients’ overall healthcare needs, ensuring mental peace and physical comfort and guaranteeing quality of life. Additionally, patients’ E-WOM mediates the relationship between SMMAs dimensions, such as interactivity and trendiness, with each dimension of patient PVCC.

This study extends the service-dominant logic and enriches the literature on healthcare service co-creation. It explores how SMMAs can enhance patient PVCC through E-WOM and improve patient well-being. Additionally, it provides valuable insights for social media marketing managers, healthcare professionals and marketing strategists.

Online health communities (OHCs) have emerged on the Internet, substantially changing the conventional healthcare delivery model. Despite this emergence, the lack of patient participation and contribution always limits the success and sustainability of OHCs. Previous studies have disclosed that patients’ value co-creation behavior (VCB) helps organizations sustain OHCs. However, how the recent surge in artificial intelligence (AI) tools, such as social support chatbots (SSCs), drives patients’ VCB is still unknown. Therefore, this study examines the complex mechanism behind patients’ VCB to establish sustainable OHCs.

Using value co-creation and social support theories, the author develops a moderated mediation model and analyzes survey data from 338 respondents using partial least squares structural equation modeling (PLS-SEM) and artificial neural network (ANN) methods.

Results demonstrate that perceived social support (PSS) from SSCs positively affects VCB directly and indirectly via patient learning (PL). This indirect effect is stronger when patient ability/readiness (PAR) is high. ANN findings highlight the model’s robustness and the significant role of PAR in VCB.

This study’s integrated framework offers unique insights into key drivers of patients’ VCB in OHCs. The findings indicate that PSS from SSCs enhances PL and VCB, with PAR influencing the strength of these relationships. Understanding these dynamics can inform user-centric interventions to promote effective learning and collaboration in OHCs.

Given the progressive rise of online health communities (OHC) that have predominantly changed health delivery services, healthcare organizations still face tremendous challenges of low patient participation and lack of high-quality contribution to OHC. Prior scholars indicated that inducing patient value co-creation behavior (VCB) is substantially beneficial for the sustainable growth of OHCs. However, what drives patients' behavior to co-create value is still unknown. To fill this important gap, this study used the service-dominant logic of value co-creation theory and face (mianzi in Chinese) literature to discover how patient co-creation attitude (CA) affects patient VCB. Also, this study aimed to explore the joint mechanism of how face gain (FG) and face loss (FL) impact patients' VCB in OHCs.

The survey data of 322 patients actively using OHC in China were analyzed via partial least squares structural equation model (PLS-SEM) and fuzzy set qualitative comparative analysis (fsQCA).

The results revealed that patient CA positively influences VCB, that is participation behavior (PB) and citizenship behavior (CB). Face gain (FG) strengthens the impact of CA and patient PB and CB, whereas face loss (FL) weakens the impact of CA and patient PB and CB. Furthermore, the fsQCA findings signify the robustness of the study model.

This study explores the multifaceted mechanism of patient value co-creation in OHC and discloses the crucial role of face for the first time. Further, the novel findings of this study provide a robust framework for advancing the understanding of important drivers of patient VCBs that significantly helps healthcare service providers and OHC managers to sustain OHCs.

As the complexity and uncertainty of infrastructural megaprojects challenge traditional management models, there is an increasing focus on value co-creation as an organizational strategy to streamline management. However, the role of value co-creation behavior in facilitating the value realization process remains underexplored. This study examines how justice perception (distributive, procedural and interactional justice) improves contractor value co-creation behavior, focusing on the mediating role of psychological ownership.

Ten hypotheses in the proposed research model were tested through partial least squares structural equation modeling using 199 valid questionnaires from China.

The results show that contractor value co-creation behavior is directly and positively influenced by procedural, distributive and interactional justice and indirectly influenced by them through the underlying psychological mechanism of psychological ownership.

The findings fill a knowledge gap by examining the effect of justice perception on contractor value co-creation behavior based on social exchange theory. Discovering justice perception will contribute to contractor value co-creation behavior, and psychological ownership mediates this relationship.

This paper aims to examine the effects of economic policy uncertainty (EPU) on accounting conservatism in Korean firms. An increase in EPU could widen information asymmetry between insiders and outsiders, to the detriment of a firm’s investment decisions, stock price and cost of capital. This paper hypothesizes that Korean firms are likely to decrease accounting conservatism during high EPU due to inefficient institutional structure and weak corporate governance, together with the vulnerability of the Korean economy to exogenous shocks.

This study measures a firm’s level of conservatism using three accrual-based models proposed by Ball and Shivakumar (2006): 1) the cash flow model (CF model), 2) the Dechow and Dichev model (DD model) and 3) the Jones model. As a robustness test, this paper uses C-score model as an alternative measure of accounting conservatism. The data set used in this study is a total of 23,109 firm-year observations during the sample period from 2000 to 2018.

The test results show that an increase in EPU adversely affects Korean firms’ accounting conservatism, and that this adverse impact is more pronounced in financially distressed and non-manufacturing firms. This study’s findings highlight the importance of institutional structure during a period of high EPU, which can create incentives for either improving or deteriorating reporting quality.

This study adds new evidence to extant literature on the effects of EPU on managers’ choice of accounting policies and demonstrates that managers in emerging markets may have different incentives to cope with country-specific EPU fluctuations.

Focusing on the Brazilian equity mutual fund industry, this study analyzes whether including the investor sentiment index in asset pricing models is important for explaining fund alpha.

The investor sentiment index and risk factors in the Fama and French (1993) and Carhart (1997) models were estimated, the risk-adjusted performance of a sample of equity mutual funds in Brazil was evaluated, and a United States (US) sample was included for a complementary perspective. The sample period spans 2010–2019 for Brazil and 2010–2018 for the US.

The results contrasted with those evidenced in the US, where the sentiment index was an important factor in explaining the probability of alpha occurrence, especially in the case of winner funds, defined as those exhibiting a positive and statistically significant alpha at the 5% level. Overall, the findings suggest that, in the Brazilian market, pricing models incorporating investor sentiment as an additional factor fail to adequately capture the outperformance probability of equity mutual funds. These results suggest that the factors influencing fund performance may differ between the two countries and highlight the relevance of developing more suitable investor sentiment indicators for emerging markets.

This study examines the impact of the sentiment index on the performance of equity mutual funds in Brazil, specifically its influence on alpha generation.

This study aims to investigate the interrelationship among consumers, celebrities and brands within social media environments. It proposes a theoretical framework based on an integrative approach that combines parasocial relationship theory and the meaning transfer model.

This study collected data from 342 Generation Z fans, and structural equation modeling was used for the analysis.

The results revealed that social media use strongly affects celebrity worship, but its impacts on brand love and online brand advocacy are weak. Celebrity worship significantly influences brand love; however, the relationship with online brand advocacy is nonsignificant, highlighting the crucial mediating role of brand love. The mediating effects of celebrity worship and brand love significantly strengthened the relationship between social media use and online brand advocacy.

By using an integrative approach, this study advances the understanding of the dynamics of consumer–brand relationships, revealing the serial mediating path that highlights the roles of celebrity worship and brand love.

In this paper, we empirically investigate how crypto investments in times of economic downturn would affect credit card usage, a widely used payment method that has a significant impact on individual financial well-being.

We carry out an ordinary least squares regression analysis and an instrumental variable design on data from the most recent National Financial Capability Study 2021 (NFCS2021). The NFCS2021 collects information about various demographic and financial backgrounds of US adults.

We find that crypto investments are associated with a significantly higher likelihood of credit card misuse, as indicated by making only the minim um payments, late payments and using credit cards for cash advances. Meanwhile, social media use is a strong predictor of crypto investments. Results from our analysis are robust after accounting for endogeneity concerns using an instrumental variable design.

Our findings provide new insights into the influence of emerging financial instruments on delinquent credit card behaviors, which can further intensify individual and household financial instability during periods of market stress. Furthermore, our findings underscore the necessity of improving individual awareness of the high-risk characteristics of cryptocurrencies, despite their increasing popularity in the financial marketplace in the current financial marketplace.

Environmental threats are becoming severe in developing and undeveloped countries. It urges to know how green banking operations can foster sustainable development in these regions. This study aims to provide empirical evidence of the determinants of green banking operations in Bangladesh.

Based on the socially responsible investing (SRI) theory, this study examined the hypothesized relationships using a partial least square structural equation modeling (PLS-SEM) approach. The Bayesian SEM (BSEM) through a Markov Chain Monte Carlo (MCMC) approach was also used to validate the study's first-order model.

The findings show that sustainable innovativeness, green investment and green banking policy substantially and positively change green banking operations. Notably, green investment is the most influential predictor of green banking operations, driving banks to establish sustainable economic systems within the country.

The findings offer valuable guidance for scholars, financial institutions, policymakers and bank managers to develop and implement effective strategies for green banking operations. These strategies may significantly contribute to achieving the sustainable development goals (SDGs) in Bangladesh.

This study is ground-breaking in associating sustainable innovativeness and green banking operations from a developing country. It enriches our understanding of green banking, aligning with existing literature. Additionally, PLS-SEM and BSEM provide strong validation of the proposed theoretical model.

The purpose of this study is to investigate the role of millennial tourists’ accommodation service experiences (ASEs) on their satisfaction, word-of-mouth (WOM) and revisit intentions (RIs) in an emerging economy.

A survey instrument was used to collect cross-sectional data from millennial tourists, and the 282 valid datasets were analyzed using structural equation modeling.

The results demonstrated that ASE had a beneficial impact on satisfaction and WOM but not on RI. Significant positive associations between tourist satisfaction, WOM and RI were also discovered. Additionally, WOM research sheds new light on how the ASE of millennial tourists affects their satisfaction, WOM and propensity to return. Furthermore, results show that WOM intentions and satisfaction mediate the relationship between ASE and RIs.

The study presents a unique research context, the application of advanced statistical techniques and the comprehensive investigation of key outcome variables in the context of millennial tourists’ ASEs in an emerging economy. This study contributes significantly to the body of knowledge in the field of tourism research, aiming to meet long-term goals in a sustainable way for the hospitality industry operators by integrating ASE, satisfaction, WOM and RI. Additionally, the study presents the mediating role of WOM and satisfaction in the millennial tourists’ emerging country context.
