Abstract

The research highlights the results of a multivariable study on the influence of purchase descriptors on consumer happiness. Using a well-established consumer decision-making paradigm, participants were randomly assigned to hypothetical scenarios in which purchase descriptors were experimentally manipulated. The variables consumer happiness, subjective well-being, consumer choice, and additional consumer attitudes were used as outcome variables. There is evidence that participants varied in terms of consumer happiness based on the specific purchase description conditions they were assigned. This research contributes to the scientific literature on consumer decision making by adding clarity to the role of important purchase-related variables on consumer happiness.

Abstract

The causes of stress in students can come from their academic life, especially from external demands and their own expectations. External demands can be in the form of coursework, course load, parents' demands to be successful in their studies, and social adjustments in the campus environment. Spiritual intelligence is able to encourage students to achieve success in their studies because spiritual intelligence is the foundation that encourages the effective functioning of intellectual intelligence and emotional intelligence. Study behavior (which consists of the habit of attending lessons, the habit of reading books, the habit of visiting the library, and the habit of taking exams) of a student greatly influences the continuity of his studies. This research is quantitative research in the form of a case study using multiple linear regression analysis methods. The results of data testing show that learning behavior can have a negative but not significant effect on college stress. The results of testing spiritual intelligence show that spiritual intelligence can have a negative but not significant effect on college stress.

Abstract

Achieving a sustainable competitive advantage is essential for improving marketing performance in highly dynamic business environments. One strategic approach to attaining this objective is through relationship learning, which enables firms to enhance their organizational learning capabilities by facilitating systematic information exchange, fostering shared learning platforms, and aligning behaviors with stakeholder expectations. Relationship learning is not limited to dyadic firm-stakeholder interactions but also encompasses insights obtained from external sources such as scientific publications and academic research. By integrating both internal and external knowledge, firms can develop a comprehensive understanding of their strategic environment, allowing them to formulate more adaptive and effective marketing strategies. The establishment of mutual understanding through continuous collaborative efforts between customers and suppliers serves as a foundation for influencing behavioral alignment and strategic coherence. This dynamic learning process significantly contributes to the development of a firm’s competitive advantage, thereby strengthening its marketing performance over time.

Abstract

This research explores the predictive capabilities of three distinct modeling approaches—Linear Regression, Random Forest, and Long Short-Term Memory (LSTM)—in forecasting stock prices using data from 29 companies, including the S&P 500 index, spanning from January 1, 2000, to June 27, 2024. Through the utilization of historical time-series data, the study evaluates model performance based on key statistical indicators: Mean Squared Error (MSE), Root Mean Squared Error (RMSE), and the coefficient of determination (R²). The findings indicate that while Random Forest outperforms Linear Regression in terms of accuracy, the LSTM model consistently delivers superior results, attributed to its strength in capturing sequential dependencies within financial data. These insights contribute to the growing body of literature in financial analytics by highlighting the comparative strengths of traditional, ensemble-based, and deep learning methods for stock market prediction. Furthermore, the study opens up avenues for integrating advanced temporal models into future financial forecasting frameworks.

Abstract

This study tries to answer some questions on the impact of Fundamental Macroeconomic Factors, Cost Efficiency, Firms Policies to Islamic Fintech Walfare from economically emerging country like Indonesia. The analysis was conducted gradually by placing systematic risk and firm performance as intervening variables. This research, in specific, aims to test the gradual effect of macroeconomic fundamental factors on firm performance and firm value. The theoretical base applied to support this research was two established financial theories, such as agency and capital structure theory. This study used the samples of the Islamic Fintch Institution that listed in Indonesia's stock exchange, which the stocks actively traded in Indonesia's Stock Exchange. The data used was panel data, namely, the data of cross section and time series from the period of 2017 to 20019. The research results are; first, the macroeconomics variables (inflation, interest rate, exchange rate, and economic growth) have significant effect on systematic risks. On the other hand, systematic risks have significant effect on firm performance, and firm performance has significant effect on firm value. Second, the variables of firm policy (manager incentive and financial leverage) have significant effect on firm performance, and firm performance has significant effect on firm value. However, capital expenditure has insignificant effect on firm performance and firm value rather than manager incentive and financial leverage. Third, special findings from this research are that there is gradual process in influencing firm value so that firm performance has the role as intervening variable, which is the variables mediating the effects of macroeconomic variable (exchange rate), systematic risk, and firm policy (manager incentive) in Islamic financial technology welfare.

Abstract

Purpose - The growing adoption of remote work has raised important questions regarding the role of human resource management (HRM) practices in safeguarding employee well-being. While well-being-oriented HRM has been recognized as an essential framework for supporting happiness, health, and social connectedness in traditional organizational settings, its relevance in remote work arrangements remains ambiguous. The reduced physical presence and visibility of employees in remote contexts may diminish the effectiveness of such practices, thereby warranting a deeper empirical investigation. Aims - This study seeks to examine whether well-being-oriented HRM maintains its capacity to enhance employee well-being in remote working environments, as compared to conventional, on-site contexts. More specifically, it aims to evaluate how distinct domains of well-being-oriented HRM are associated with different facets of employee well-being—including psychological well-being (happiness, job satisfaction, and engagement), physical well-being (strain and health), and relational well-being (social connectedness). Additionally, the moderating role of remote work intensity is assessed to determine whether variations in the extent of remote work influence these relationships. Design - The empirical analysis was conducted using a two-wave dataset collected from 258 Indonesian state-owned manufacturing enterprises. By differentiating between remote and non-remote work settings, the study applies a comparative lens to assess both the direct associations of well-being-oriented HRM with well-being outcomes and the potential moderating influence of remote work intensity. This approach allows for a nuanced understanding of how HRM practices function across varying organizational work arrangements. Findings - The results indicate that well-being-oriented HRM continues to exert a positive influence on employee well-being in remote work contexts, particularly in terms of happiness (engagement and job satisfaction) and health (strain reduction). However, variations emerge across domains of HRM, as certain practices appear more effective in enhancing happiness and health-related outcomes than others.

Abstract

Researchers want to know the effects of cognitive dissonance bias, hindsight bias, overconfidence bias, and self-control bias on Stock Option investment decisions. The researcher uses the technical analysis of convergent validity test, discriminant validity test, outer model test, inner model test, rsquare, hypothesis test and Sobel test. The program used is SmartPLS 3 trial version with a sample of 224 respondents with predetermined criteria. The results show that the cognitive dissonance bias variable on Stock Option investment decisions has no significant effect, the hindsight bias variable has no effect on Stock Option investment decisions, overconfidence bias has a positive but not significant effect on Stock Option investment decisions. This is because the T-statistic value is less than 1.97. While the self-control variable can have a positive and significant effect on Stock Option investment decisions.
