The Impact of Industry Concentration on Stability: The Case of Indonesian Islamic-Commercial Banks

This study aims at investigating the impact of the banking industry’s concentration on the stability of Islamic commercial banks in Indonesia. This study used a single country setting of 14 Islamic-commercial banks in Indonesia from 2011 to 2020. The data utilized in this study comprised all Islamic-commercial banks' assets in Indonesia, excluding commercial banks with Islamic business units. The influence of concentration level on the stability of Islamic-commercial banks was investigated using a panel data model. According to Hausman's test, the fixed-effect model is more suitable than the random-effect model. The findings indicate that the “concentration-stability” hypothesis was supported-robust using two concentration level measurements: CR4 and HHI. It is implied that banks tended to be more stable at the higher competition level. From the bank’s specific characteristics, only the cost-to-income ratio significantly influenced the bank's stability, as expected. Other bank-specific characteristics, such as bank size, credit risk, and income diversity, had no substantial influence on observed bank stability. A robustness check was performed by estimating new models that included multiple control variables that did not change the effect of concentration level on the bank’s stability. This study adds to the literature by demonstrating the “concentration-stability” hypothesis in the Indonesian Islamic-commercial banking industry. Moreover, this study’s results confirm the previous study’s findings using different methods and measures of industry concentration. In addition, this study is relevant in the context of the merger action of three large Islamic commercial banks

Market share and efficiency: Causality test in Indonesian general insurance industry

This study aims to analyze the relationship between market share and technical efficiency in the Indonesian general insurance industry. The data for the period 2010-2020 is used, which was obtained from the Indonesian Financial Services Authority (OJK). The results show that efficient companies emerged from the category of industry possessing comparatively higher and lower market shares. Furthermore, the panel Granger-causality test indicates a one-way direction of causality, where only the market share has an impact on the technical efficiency score. The panel regression using the Feasible Generalized Least Square (FGLS) model shows that market share has a negative impact on technical efficiency scores. Other variables, such as the age of the industry, merger, and acquisition are listed in the stock exchange and do not have a significant effect on the efficiency score. Based on the aforementioned findings, it can be inferred that the quiet-life hypothesis is applicable within the Indonesian general insurance sector. Consequently, the government must foster competition among the businesses operating within the industry

Determination of Optimal Portfolio by Calculating Transaction Costs using Genetic Algorithms on the Jakarta Islamic Index

The optimal portfolio is a portfolio that can provide maximum returns at the same level of risk. In investing, the term "high return, high risk" is known, meaning that the higher the return, the higher the risk. Therefore, investors need to develop an optimal portfolio to obtain the maximum return on investment at the same level of risk. This study aims to determine the optimal formation of a stock portfolio by calculating transaction costs using the genetic algorithm method on stocks that are members of the Jakarta Islamic Index. This research uses data of daily return on stocks included in Jakarta Islamic Index from 1 August 2020-1 August 2022. The dataset consists of two variables: the date of observation and daily stock returns. The method used in this study is the minimum variance method and the genetic algorithm. Data analysis was divided into two stages: model formulation and model testing through case studies. The analysis of optimal portfolio formation using genetic algorithms shows that in terms of performance, the minimum variance portfolio is superior to the genetic algorithm portfolio, as indicated by the Sharpe ratio value. Meanwhile, the genetic algorithm portfolio is superior to the minimum variance portfolio regarding transaction costs. The genetic algorithm portfolio can provide a fairly high total return, small transaction costs, and good performance compared to the minimum portfolio. Hence, the genetic algorithm portfolio is worthy of recommendation to investors

ANALISIS KETIDAKPASTIAN PENGUKURAN KEKUATAN TARIK DAN ELONGASI SPESIMEN SS304 BERBENTUK RING. Ketidakpastian adalah tolok ukur dari kehandalan suatu pengukuran. Salah satu pendekatan analisa ketidakpastian yang banyak digunakan adalah dengan menggunakan Guide to the expression of uncertainty in measurement (GUM). Langkah-langkah untuk menganalisa ketidakpastian dari suatu pengukuran telah dijelaskan secara rinci oleh pendekatan GUM. Analisa ketidakpastian dilakukan pada pengujian tarik untuk mengetahui ketertelusuran data yang diperoleh. Pengujian tarik menghasilkan data berupa kekuatan tarik dan elongasi dari material uji.  Kekuatan tarik adalah besaran yang melibatkan besaran gaya dan panjang. Elongasi adalah penambahan panjang saat dilakukan penarikan. Kekuatan tarik pada sampel berbentuk ring akan dipengaruhi oleh luas penampang pada kedua belah sisi ring ketika diberikan tegangan tarik. Sehingga untuk menentukan ketidakpastian pengujian tarik akan memerlukan analisa terhadap penyumbang ketidakpastian. Makalah ini memberikan penjelasan bagaimana cara untuk menganalisa ketidakpastian pengukuran kekuatan tarik dan elongasi pada sampel berbentuk ring. Selain itu juga akan diperoleh nilai ketidakpastian pengukuran kekuatan tarik dan elongasi SS304 berbentuk ring. Dari pengujian yang dilakukan dapat diketahui bahwa kekuatan tarik ring SS304 rata-rata adalah 631,070 ± 26,976 Nmm-2 dengan ketidakpastian diperluas sebesar 50,451 Nmm-2 pada tingkat kepercayaan 95%. Selain itu pada tingkat kepercayaan yang sama diperoleh hasil elongasi ring SS304 rata-rata 18,681% ± 2,425% dengan ketidakpastian diperluas sebesar 2,867%.
