Given the difficulties in finding significant exchange rate exposure in the extant literature, this paper attempts to resolve the so-called “exposure puzzle” by investigating whether currency movements have any significant impact on international industry returns.

This paper utilizes the multivariate Generalized AutoRegressive Conditional Heteroskedasticity (MGARCH) methodology to estimate both symmetric and asymmetric exchange rate exposures for each industry common across 12 countries simultaneously.

The empirical results show that exchange rate exposure is not only statistically significant but also economically important based on the estimation of an asymmetric three-factor exposure model using MGARCH methodology. This is an extremely important finding as it suggests that the “exposure puzzle” may not be a puzzle at all once a better methodology is utilized in the estimation.

Because this study tries to resolve the exchange rate exposure puzzle by focusing on whether exchange rate movements affect ex-post returns as opposed to ex ante expected returns and given the significant exposures with respect to different risk factors found in the study, it is interesting to see if any of these risk factors commands a risk premium. In other words, a natural extension of this study is to test whether any of these risk factors is priced in international industry returns.

The findings of the study have interesting implications for international investors who would like to diversify their portfolios across different industries and are concerned about whether the unexpected movements in the bilateral exchange rates will affect their portfolio returns in addition to its interest rate and world market risk exposures.

The study utilizes the MGARCH methodology, which has not been fully exploited in the exchange rate exposure literature.

Misperceptions hinder our ability to effectively respond to health crises such as the COVID-19. We aimed to examine the dynamic influences between information exposure, information trust and misperceptions during the early phase of the COVID-19 pandemic. Specifically, we focused on the relative influence of exposure to COVID-19-related information via social media versus interpersonal offline communication.

The current study conducted a two-wave national survey of US adults in May and June of 2020 with a two-week time interval. A professional polling firm recruited participants, and 911 and 679 respondents participated in the first and the second wave survey, respectively. To test proposed hypotheses, researchers conducted path analyses using AMOS 27.0.

Findings show that individuals exposed to COVID-19-related information via social media are likely to hold increased misperceptions. In contrast, exposure to COVID-19-related information offline did not elicit any effects on misperceptions. The exposure to information on social media was positively associated with trust in that information, which, in turn, contributed to an increase in misperceptions. Furthermore, when examining the effects of misperception, it was found that misperceptions increased the likelihood of individuals being exposed to and having trust in COVID-19-related information on social media. The findings provide valuable insights into the role of social media as a platform where a detrimental cycle thrives, shaping the formation of misperceptions and cultivating a heightened dependence among individuals with elevated misperceptions.

The current study significantly extends the findings of prior research by examining the differential effects of social media and interpersonal communication offline on misperception and by revealing the intricate dynamics between information exposure and misperception by focusing on the role of trust. The findings emphasize the detrimental role of social media in generating a vicious information cycle. That said, seemingly superficial discussions about health crises within a social media environment rich in misinformation can contribute to fueling a self-reinforcing loop, making it challenging to effectively counteract misperceptions.

The occupational health risk associated with the production of prefabricated concrete components is often overlooked. This paper will use a damage assessment and cyclic mitigation (DACM) model to provide individualized exposure risk assessment and corresponding mitigation management measures for workers who are being exposed.

The DACM model is proposed based on the concept of life cycle assessment (LCA). The model uses Monte-Carlo simulation for uncertainty risk assessment, followed by quantitative damage assessment using disability-adjusted life year (DALY). Lastly, sensitivity analysis is used to identify the parameters with the greatest impact on health risks.

The results show that the dust concentration is centered around the mean, and the fitting results are close to normal distribution, so the mean value can be used to carry out the calculation of risk. However, calculations using the DACM model revealed that there are still some work areas at risk. DALY damage is most severe in concrete production area. Meanwhile, the inhalation rate (IR), exposure duration (ED), exposure frequency (EF) and average exposure time (AT) showed greater impacts based on the sensitivity analysis.

Based on the comparison, the DACM model can determine that the potential occupational health risk of prefabricated concrete component (PC) factory and the risk is less than that of on-site construction. It synthesizes field research and simulation to form the entire assessment process into a case-base system with the depth of the cycle, which allows the model to be continuously adjusted to reduce the occupational health damage caused by production pollution exposure.

Taking advantage of distinctive text-based measures of climate policy uncertainty and firm-specific exposure to climate change, this study aims to examine the impact of firm-specific vulnerability on dividend policy.

To mitigate endogeneity, the authors apply an instrumental-variable analysis based on climate policy uncertainty as well as use additional analysis using propensity score matching and entropy balancing.

The authors show that an increase in climate policy uncertainty exacerbates firm-specific exposure considerably. Exploiting climate policy uncertainty to generate exogenous variation in firm-specific exposure, the authors demonstrate that companies more susceptible to climate change are significantly less likely to pay dividends and those that do pay dividends pay significantly smaller dividends. For instance, a rise in firm-specific exposure by one standard deviation weakens the propensity to pay dividends by 5.11%. Climate policy uncertainty originates at the national level, beyond the control of individual firms and is thus plausibly exogenous, making endogeneity less likely.

To the best of the authors’ knowledge, this study is the first attempt in the literature to investigate the effect of firm-specific exposure on dividend policy using a rigorous empirical framework that is less vulnerable to endogeneity and is more likely to show a causal influence, rather than a mere correlation.

This study aims to investigate how a firm's management team's capacity to efficiently use its resources affects the firm's exposure to climate change. Specifically, the authors investigate the intriguing question – does managerial ability affect a firm's climate change exposure?

The authors use an unbalanced panel dataset of 4,230 US based firms listed on Compustat from 2002–2019 and test the hypothesis by panel regression analysis. To mitigate endogeneity concerns, difference-in-differences and instrumental variable approaches are used.

The baseline analysis shows a negative, statistically significant impact of managerial ability on climate change exposure. The findings hold after controlling for endogeneity using two-stage least squares regression and difference-in-differences tests. The authors find the negative effect is stronger for managers engaged in socially responsible activities, and after climate change issues receiving greater public awareness following the 2006 release of the Stern Review and the 2016 signing of the Paris Accord.

Motivated by the resource-based theory and the natural resource-based view of the firm model, the empirical results support the view that greater managerial ability protects the firm against environmental challenges through efficient use of firm resources. Compared with traditional climate change measures that are plagued by disclosure issues, the use of the Sautner, Van Lent, Vilkov and Zhang's machine learning based dataset utilizing earning conference calls provides stronger, robust findings that will be useful to management and investors in environmental performance assessments.

Research has established the prevalence and relevance of moral injury in healthcare workers, though less attention has been paid to the different classes of potentially morally injurious events (PMIEs) experienced by this population and their impact. This exploratory study sought to examine the frequency of self- and other-generated PMIE classes and their associations with demographic characteristics and well-being outcomes among mental healthcare staff.

Secondary analysis of data drawn from two cross-sectional surveys of 267 frontline and leadership staff from mental healthcare settings in the UK was conducted. Responses on the Moral Injury Events Scale and the Short Professional Quality of Life Scale were extracted for analysis.

Betrayal by others was most frequently endorsed (61.8%), whilst self-transgressions were least frequently reported (25.5%). After controlling for the number of PMIE classes experienced, betrayal significantly predicted secondary traumatic stress (p = 0.01) and burnout (p = 0.04). Additionally, other transgressions significantly predicted secondary traumatic stress (p = 0.008). The predictive effects of self-transgressions on burnout, secondary traumatic stress and compassion satisfaction were all nonsignificant after controlling for the number of PMIE classes experienced.

Findings highlight differences in the frequency and impact of self and other PMIEs experienced by healthcare professionals. Reducing cumulative exposure to differential PMIE classes appears to be of critical importance to improving occupational well-being in this group.

To our knowledge, this study is the first to explore the associations between PMIE classes and occupational well-being in a mental healthcare population, inclusive of frontline and leadership staff.

This study aims to examine the moderating effect of media exposure and media legitimacy on the environmental audit committee (EAC) regarding environmental disclosure quality as measured by voluntary and timely disclosure.

This paper was based on a sample of 81 French nonfinancial companies listed on the SBF 120 index and covered a six-year period; from 2014 to 2019. To test the hypotheses, a feasible generalized least squares regression was applied. Moreover, the authors checked the results using an additional analysis and the generalized method of moment model for endogeneity problems.

The results obtained show that for 482 French firm-year observations during the period 2014–2019, the media exposure does not play a moderating role between the EAC and the voluntary environmental disclosure; However, it plays a moderating role between the EAC and the timely environmental disclosure. The results also show that media legitimacy plays a moderating role between the EAC and the quality of environmental information. After testing for endogeneity problems, the findings remain unchanged.

The findings of this study may be of interest to academic researchers, practitioners and regulators who are interested in determining the quality of environmental disclosure by considering the role of the EAC while giving a role to media exposure and media legitimacy in the French context. Considering the EAC as a powerful source of effective corporate governance to improve the quality of environmental disclosure for decision-making, the research provides valuable insights for policymakers and managers on the importance of this mechanism and the importance of the environmental media and its tone in making environmental reporting useful and relevant.

The originality of the work lies in the fact that it is one of the first works that deal with the moderating effect of media exposure on the relationship between the EAC and the quality of environmental information disclosure measured by voluntary and timely disclosure. To the best of the authors’ knowledge, no previous empirical studies have been conducted on this relationship in the French context or in other contexts.

The authors investigate whether firm-specific vulnerability to climate change influences foreign exchange hedging, using a novel text-based measure of firm-level climate change exposure generated by state-of-the-art machine-learning algorithms.

The authors' empirical analysis includes firm-fixed effects, random-effects regressions, propensity score matching (PSM), entropy balancing, an instrumental-variable analysis and using an exogenous shock as a quasi-natural experiment.

The authors' findings suggest that greater climate change exposure brings about a significant reduction in exchange rate hedging. Companies more exposed to climate change may invest significant resources to address climate change risk, such that they have fewer resources available for currency risk management. Additionally, firms seriously coping with climate change risk may view exchange rate risk as relatively less important in comparison to the risk posed by climate change. Notably, the authors also find that the negative effect of climate change exposure on currency hedging can be specifically attributed to the regulatory aspect of climate change risk rather than the physical dimension, suggesting that companies view the regulatory dimension of climate change as more critical.

Recent studies have demonstrated that climatic fluctuations represent one of the most recent sources of unpredictability, thereby impacting the economy and financial markets (Barnett et al., 2020; Bolton and Kacperczyk, 2020; Engle et al., 2020). The authors' study advances this field of research by revealing that company-specific exposure to climate change serves as a significant determinant of corporate currency hedging, thus expanding the existing knowledge base.

Considering the detrimental impact of workplace cyberbullying on employees and organizations, it is necessary to understand factors that potentially induce employees to engage in cyberbullying and to recognize personal characteristics that may help employees mitigate its impact. This research applies the conservation of resources (COR) theory to investigate the effect of organizational politics and political skill on employees' exposure to workplace cyberbullying as well as to analyze the subsequent impact on emotional exhaustion. Moreover, the interaction effect of political skill and organizational politics on employees' exposure to workplace cyberbullying is analyzed.

The total of 358 complete questionnaires were obtained from one medium-sized public university in Thailand. The partial least squares structural equation modeling (PLS-SEM) was used to analyze the data.

The analysis supports the positive association between organizational politics and employees' exposure to workplace cyberbullying. Employees' exposure to workplace cyberbullying also has a positive association with emotional exhaustion. On the other hand, the analysis showed that political skill has a negative association with employees' exposure to workplace cyberbullying. The result from the moderating effect analysis further shows that political skill also reduces the impact of organizational politics on employees' exposure to workplace cyberbullying.

The incorporation of the COR theory provides theoretical insight into how political skill of employees can buffer the impact of organizational politics on exposure to workplace cyberbullying. It advances the knowledge found in previous research that lacked solid theory to explain the interaction between organizational politics and political skill of employees in the area of workplace cyberbullying.

This study seeks to comprehend if political exposure containing disapproval and different values will affect implicit knowledge sharing (KS) amongst colleagues in the organization. This research examines participants' responses to a colleague's social-media political exposure and their readiness to perform implicit KS to their colleague.

Data collection uses an online questionnaire and a vignette approach. Subsequently, data analysis for 316 finished surveys employs structural equation modelling-partial least squares (SEM-PLS).

The findings show that the perceived-value similarity of political posts of a colleague significantly and indirectly affects workers' readiness to do implicit KS. Besides, likes and trusts also significantly affect workers' readiness to perform implicit KS. While perceived-value similarity strongly shapes likes, likes significantly and positively affect trusts.

Sharing social-media postings associated with political exposure can hinder the implicit KS in organizations and is understudied in the field of knowledge management. Especially, unlike this study which focuses on private companies, previous studies have paid more attention to public enterprises. Besides, this paper's empirical verification is obtained from private organizations in Indonesia, which is also neglected by scholars.
