Abstract

In the motor vehicle insurance market, insurance companies need to know an estimate of the number of claims and the value of compensation they will face in the next policy period, and need to estimate the aggregate payment. In this study, the number of claims is assumed to have a Poisson distribution and the compensation value is assumed to be of a Lognormal distribution. Bayesian sensibilities will be used in shaping the predictive distribution of aggregate payments. Therefore, the Gamma distribution is used as the prior Poisson distribution, while the prior distribution of Lognormal is the Inverse χ ^ 2 distribution and the Normal distribution. The purpose of this paper is to provide an estimate of adequate reserve funds for motor vehicle insurance companies. Estimates of reserve funds are obtained from percentiles of the distribution of aggregate payments. Monte Carlo simulation techniques are used to estimate the aggregate distribution of payments. The test results show that the Poisson and Lognormal models are suitable in modeling the real data used in this paper. The simulation results from the predictive distribution show that the 95th percentile is IDR 404,368,169, so that this value can be used as an estimate of adequate reserve funds. The results of this study are expected to provide new information that is useful for motor vehicle insurance companies when estimating adequate reserve funds.

Abstract

Keterampilan bagaimana mengelola keuangan pribadi yang baik berpengaruh sangat besar terhadap kebebasan finansial. Mahasiswa harus mulai membentuk kebiasaan-kebiasaan bagaimana mengelola keuangan yang sehat agar kesejahteraan keuangannya terwujud. Penelitian ini dilaksanakan untuk menginvestigasi hubungan kausalitas antara peran orang tua, financial attitude, financial behavior, dan financial decision. Survei dilakukan secara daring pada 200 responden yang merupakan mahasiswa Fakultas Ekonomi Universitas Garut. Data kemudian dianalisis menggunakan Structural equation modeling (SEM) dan bantuan alat analisis AMOS 21. Hasil dari penelitian ini menerangkan bahwa peran orang tua berpengaruh positif dan signifikan terhadap financial attitude; financial attitude berpengaruh positif dan signifikan pada financial behavior; serta financial behavior berpengaruh positif dan signifikan pada financial decision. Namun, peran orang tua pengaruhnya kecil terhadap financial behavior dari mahasiswa.

Abstract

This study aims to investigate the factors influencing accounting students' intention to pursue a career in Islamic banking, by using a structural equation model. The study combines the Theory of Planned Behavior (TPB) and the religiosity concept to examine the effects of soft skills self-efficacy, technical skills self-efficacy, social influence, job market consideration, and Islamic religiosity on accounting students' intention to pursue a career in Islamic banking. Data were collected through a survey of 264 accounting students at Universitas Garut. The results show that soft skills self-efficacy, social influence, and Islamic religiosity have a significant positive impact on student's intention to pursue a career in Islamic banking. However, technical skills self-efficacy, and job market consideration do not significantly influence students' intentions. These findings provide insight for Islamic banks on how to attract potential employees to pursue a career in Islamic banking. The study contributes to the literature by incorporating Islamic religiosity in the TPB model to explain accounting students' career intentions in Islamic banking, which is particularly relevant in the context of Indonesia, a predominantly Muslim country.

Abstract

Jaminan Kesehatan Nasional (JKN) aims to provide affordable healthcare services to all Indonesian citizens. However, despite its admirable goals, the program has encountered challenges related to low participation rates in various regions, including Garut. While the JKN program aspires to achieve universal healthcare coverage, its effectiveness relies on the number of individuals enrolled in the program. The significance of this research lies in the need to comprehend the factors that influence individual participation in the JKN program, particularly in areas like Garut. To address these issues, this study will investigate the determinants of people's inclination to become JKN program participants and how these factors impact their actual behavior. The research will be carried out in Garut, Indonesia, involving both JKN participants and non-participants who will take part in a survey. The collected data will undergo analysis using Partial Least Square Structural Equation Modeling (PLS-SEM) to explore the cause-and-effect relationships among the variables under examination. Additionally, Multigroup Analysis (MGA) will be employed to assess whether these causal relationships differ between the two population subgroups
