Abstract

Credit life insurance provides protection and guarantees to policyholders as debtors within the coverage period. Each insurance participant is required to pay premiums on time, namely at the beginning before the credit is issued by the bank. Net premiums can be determined using annuity calculations using the equivalence principle. Premium payments on credit life insurance are made at once taking into account mortality based on age, gender, and interest rates of 15.5% and 10.26% with a loan term of 8 years. The results of the analysis of the single premium value for the interest rate of 15.5% and 10.26% at the age of 36, 44, and 52 years showed that the interest rate and age had an effect on the premium price. The obligation of the insurance company is to pay claims to insurance participants. Insurance companies are required to have a benefit reserve fund to anticipate excess claims. Benefit reserves are the amount of money collected by the insurance company during the coverage period in preparation for claim payments. The calculation of benefit reserves in this study uses the prospective method. In the large calculation of the benefit reserves for interest rates of 15.5% and 10.26% at the age of 36, 44, and 52 years, the value of the benefit reserves decreased from the first year to the last year.

Abstract

Based on the 2020 Insurance Statistic Data released by OJK, the ratio of gross claims to gross premiums has increased due to the growth of gross premiums followed by increasing claims paid. Thus, the insurance company is obliged to provides claim reserve that is important to be estimated appropriately, especially outstanding claim reserves. This is because outstanding claim reserves are needed to cover underpayment on future claims. One popular method to estimate outstanding claim reserves is the Chain Ladder method. This study aims to determine the results of the estimated outstanding claim reserves on general insurance using Mack’s CL method. CL method is a method to estimate claim reserves simply without satisfying certain distribution assumptions. This study uses incremental run-off triangle data taken from Weindofer's research article (2012) with an event period of 2005-2012 and a development period of 8 years. Based on the calculations in this study, an estimated outstanding claim reserve of USD 20,109.82 was obtained, meaning the funds that must be prepared amounted to USD 20,109.82 in 2013 by the general insurance company that owns the data studied. It also serves as a benchmark in the determination of claim reserves in the 2013 financial statements

Abstract

Portfolio optimization using downside deviation is an optimal portfolio by defining the standard deviation of returns below the target (benchmark) as a level of risk measure. Every optimal portfolio certainly has risks. Therefore, it’s necessary to estimate the risk as an illustration of the worst investment condition. Expected shortfall is a measure of risk because it fulfills the coherent risk measures, and its estimated value exceeds VaR. This study aims to obtain optimal portfolio results using the downside deviation method and estimate portfolio risk using the expected shortfall model. The data used in this study are five stocks with the highest average trading volume that are incorporated into IDXHEALTH, namely SAME.JK, KLBF.JK, MIKA.JK, SIDO.JK, and IRRA.JK during the study period from 1 January 2020 to 23 September 2022. As a result obtained from this study, the combined weight of each stock in the optimal portfolio formed is, 2,8% in SAME.JK, 55,63% in KLBF.JK, 26,56% in MIKA.JK, 0,21% in SIDO.JK, and 14.8 % on IRRA.JK with a portfolio return of 0.0249%. The expected shortfall estimation value obtained accurately at a 99% confidence interval of 0.0399, whose value exceeds VaR (0.0343).

Abstract

One of the basics in calculating insurance premiums is life table. There are two types of life tables, namely select and non select table. The purpose of the study was to calculate premiums using a select table with a two-year select period and a non-select table in term joint life insurance for 10-term insurance and endowment insurance. The select tables used are select life table with a two-year select period and non- select life table model. The result obtained is that the premium value in term joint life insurance for 10-term insurance and endowment insurance calculated using the select table model is smaller than using the non- select table. Beside that, it is obtained that the difference gets bigger as the couple gets older.

Abstract

Exchange rates play a crucial role among macroeconomic variables, exerting a significant influence on a country's economic landscape. Fluctuations in these rates can impact a nation's stability and economic activities. Consequently, it becomes essential to engage in forecasting endeavors, particularly in predicting the exchange rate of the rupiah against foreign currencies, with a focus on the US dollar. Certain instances in financial data reveal an asymmetric volatility response, often referred to as the leverage effect. To address this challenge, asymmetric GARCH models, including EGARCH, TGARCH, and APARCH, prove instrumental. This research endeavors to identify the most effective model among EGARCH, TGARCH, and APARCH using data pertaining to the rupiah's exchange rate against the US Dollar from March 2, 2020, to June 2, 2022. The findings indicate that the APARCH (1,2) model stands out as the optimal choice for predicting volatility, boasting the smallest AIC value in comparison to its counterparts. As per the research outcomes, volatility witnessed a decline from the initial day to the fourteenth day.
