A new method of measuring stock market manipulation through structural equation modeling (SEM)

This study investigates the effects of inventory management on customers` satisfaction with lead time as a moderator variable in government-owned hospitals in Delta State, Nigeria. It aims to contribute to the extant literature on inventory management and customer satisfaction in developing countries, focusing on Delta State in Nigeria. Two hundred and sixty-five (265) questionnaires were distributed, comprising one hundred and five to measure inventory management variables administered among Medical Doctors, Nurses, Pharmacists, and Medical Laboratory Scientist. Similarly, one hundred and sixty questionnaires designed to measure customer satisfaction were administered to Patients. The study adopts multiple regression and structural equation modeling to analyze the data. Also, studying the impact of inventory management on customers` satisfaction some marketing analysis approaches were used. The obtained results support the appropriateness of the model as lead time possesses the qualities of a moderator between strategic supplier partnership, lean inventory, and information technology that are proxies of inventory management and customer satisfaction. Besides, the results record a positive and statistically significant relationship between strategic supplier partnership, lean inventory, and customer satisfaction at a 5 percent level of significance, respectively.
In addition, lead time has a positive and statistically significant relationship with customer satisfaction. Impliedly, this study concludes that inventory management proxies and lead time drive customer satisfaction. Thus, the government is recommended to focus on the lead time to avert the dearth of basic inventories in the hospitals.

Financial management behavior is an implementation action of planning and managing a person’s financial resources, both in consumption and investment activities, which can show a person’s characteristics in financial management based on the risks that arise so that each needs good control. This study aims to determine the impact of financial literacy and financial attitude on financial management behavior, mediated by the behavioral intentions of university students. The participants in this study are undergraduate students currently enrolled at prestigious private universities in Medan (North Sumatra, Indonesia). This study’s population and sample consisted of students from the Faculty of Economics and Business at Private Universities in North Sumatra, Indonesia. Purposive and snowball sampling were used with data collection techniques, namely online questionnaires. The Likert scale measures indicators in responses to statements and questions. There were 150 respondents for this study’s data collection. The findings of the study indicate that financial literacy influences financial management behavior and behavioral intentions (p < 0.05). Financial attitude affects financial management behavior (p < 0.05), financial attitude does not affect behavioral intentions (p > 0.05), and behavioral intention affects Financial Management Behavior (p < 0.05). Behavioral intentions do not mediate the effect of financial literacy on Financial Management Behavior (p > 0.05), and the effect of financial attitudes on Financial Management Behavior is not mediated by behavioral intentions (p > 0.05).

The behavior of investors and their investment decision-making process in the financial markets are guided by psychological (sentiments) and personal characteristics (personality traits). Research in recent years has shown the connection between investor sentiment and personality traits and investment decisions. Though academic works in the field of behavioral finance are growing, studies on personality traits and investment decision-making with investor sentiment as a mediator are sparse. To this end, the paper aims to analyze the effects of Indian retail investors’ Big-five personality traits (Neuroticism, Extraversion, Openness to experience, Agreeableness, and Conscientiousness) on their short-term and long-term investment decision-making with the mediating effect of investor sentiment. The study employs the Partial Least Square-Structural Equation Model to test the framed hypotheses. The findings of the study reveal that Neuroticism has a significant positive effect (β=0.352, p<0.05) on investor sentiment. It further shows that Extraversion has a significant positive effect (β=0.186, p<0.05) on long-term decision-making. On the contrary, the consciousness trait has a significant negative effect (β=-0.335, p<0.05) on short-term investment decision-making. Furthermore, the Openness trait demonstrates a significant effect on both short-term and long-term investment decision-making (β=0.357, p<0.05; β=0.007, p<0.05). However, the findings reveal no significant intervening effect of investor sentiment between personality traits and investment decision-making. Thus, the study strongly exerted the impact of investors’ personality traits on their investment decision-making due to the high influence of personal characteristics over sentiment effects.
