The purpose of this study is to address why managers enter the excessive market. A comparison of the facts and perceptions of entrants relative to success in the market shows that many entrants are confident about the viability of their businesses and enter the market. Accordingly, the authors simulate market entry decisions to detect behavioral biases.

The authors adapted the entry decisions simulation method, which is supported by the theoretical foundations of signal detection theory (SDT) and signaling theory. The simulation model is implemented on the Anaconda platform and written in Python 3.

The results of this study suggest that overestimation relates to excess market entry. Also, the proportion of excess entry under difficult conditions is always higher than under easy conditions.

This research helps managers and firms think about their and their competitors' abilities and evaluate them before entering the market. Policymakers and practitioners can also design programs such as experiential learning to help entrants assess their skills.

So far, no research has investigated the role of overconfidence under different market conditions. Accordingly, this study contributes to the current market entry literature by disentangling the debate between absolute and relative confidence and by considering the role of task difficulty.

This study aims to assess the spread of environmental literacy graduation requirements at public universities in the USA, and to highlight factors that mediate the adoption of this curriculum innovation.

The author analyzed the undergraduate general education curriculum requirements at all 549 public BA-granting higher education institutions in the USA between 2020 and 2022.

The study found that only 27 US public universities out of 540 have an environmental literacy graduation requirement, which represents 5% of universities and is substantially lower than previous estimates.

First, this study provides a more complete, more reliable and more current assessment of the graduation requirement’s presence at US tertiary institutions, and shows the number of universities that have implemented this innovation is lower than was estimated a decade ago. Second, it draws from the scholarship on the infusion of sustainability into the university curriculum to provide a comprehensive discussion of factors that mediate the pursuit and implementation of the graduation requirement. As well, it identifies factors that played a key role in one pertinent case.

Recent studies suggested the ratio of option to stock volume reflected the private information. Informed traders were drawn to the options market for its leverage effect and relatively low transaction costs. Informed traders use different intervals of option moneyness to execute their strategies. The question is which types of option moneyness were traded by informed traders and what information was reflected in the market. In this study, the authors focused on this question and constructed a method for capturing the activity of informed traders in the options and stock markets.

The authors constructed the daily measure, moneyness option trading volume to stock trading volume ratio (MOS), to capture the activity of informed traders in the market. The authors formed quintile portfolios sorted with respect to the moneyness option to stock trading volume ratio and provided the capital asset pricing model and Fama–French five-factor alphas. To determine whether MOS had predictive ability on future stock returns after controlling for company characteristic effects, the authors formed double-sorted portfolios and performed Fama–Macbeth regressions.

The authors found that the firms in the lowest moneyness option trading volume to stock trading volume ratio for put quintile outperform the highest quintile by 0.698% per week (approximately 36% per year). The firms in the highest moneyness option trading volume to stock trading volume ratio for call quintile outperform the lowest quintile by 0.575% per week (approximately 30% per year).

The authors first propose the measures, moneyness option trading volume to stock trading volume ratio, that combined with the trading volume and option moneyness. The authors provide evidence that the measures have the predictive ability to the future stock returns.

Children's food insecurity experiences are largely unrepresented in academic literature. Parents and caregivers cannot always accurately evaluate their children's attitudes or experiences, and even within the same family unit, children and their parents may report differing views and experiences of family food insecurity. The purpose of this narrative review is to identify studies that include children's voices and their perceptions, understanding, and experience of food insecurity in the household.

This narrative review aimed to address the following questions: (1) “What research studies of household food insecurity include children's voices?” and (2) “Across these studies, how do children perceive, understand and experience food insecurity in the household?”. A database search was conducted in October 2022. After inclusion and exclusion criteria were applied, 16 articles remained for review.

The findings from this review were organised into three themes: Theme 1: Ways children coped with accessing food or money for food; Theme 2: Food-related strategies children used to avoid hunger; and Theme 3: Children attempt to mask food insecurity.

Future research should further explore the long-term consequences of social pressures and informal economic engagement on children's well-being and social development. By addressing the social determinants of food insecurity, this study can strive to create supportive environments that enable all children to access adequate nutrition and thrive.

Overall, the findings of this review demonstrate the significant social pressures that shape children's responses to food insecurity. Results suggest that children's decision-making processes are influenced by the desire to maintain social standing and avoid the negative consequences of being food insecure. As such, this review underscores the need for a comprehensive understanding of the social context in which food insecurity occurs and the impact it has on children's lives. Understanding these dynamics is crucial for developing effective interventions and policies addressing the multifaceted challenges food insecure children face.

This review has highlighted a need for interventions to incorporate trauma-informed strategies to protect children from and respond to the psychologically distressing experiences and impact of living in food insecure households.
