Accurate Estimated Model of Volatility Crude Oil Price

Crude oil price (COP) data are time-series data that are assessed as having both volatility and heteroscedasticity variance. One of the best models that can be applied to address the heteroscedasticity problem is GARCH (generalized autoregressive conditional heteroscedasticity) model. The purpose of this study is to construct the best-fitted model to forecast daily COP as well as to discuss the prepared recommendation for reducing the impact of daily COP movement. Daily COP data are observed for the last decade, i.e., from 2009 to 2018. The finding with the error of less than 0.0001 is AR (1) – GARCH (1,1). The implementation of the model is applicable for both predicting the next 90 days for the COP and its anticipated impact in the future. Because of the increasing prediction, it is recommended that policymakers convert energy use to renewable energy to reduce the cost of oil use.

Characteristics of banks as determinants of profit management for islamic and conventional banks in ASEAN

This study aims to analyze company characteristics as a determinant of conventional and Islamic bank earnings management in several ASEAN countries (Association of South East Asian Nations). The Multiple Discriminant Analysis was applied to determine the differences between Islamic and Conventional Banks. This test was conducted based on Capital Adequacy Ratio, Income Before Tax and Interest, Non-Performaning and Changing Loans, and Company's Size in the banks of Indonesia, Malaysia, and Brunei Darussalam from 2014-2018. The data obtained from 200 banking entities were analyzed discriminatively. The results showed that there were simultaneous differences between Capital Adequacy Ratio, Earnings Before Tax, Loan Loss Provision, Non-Performing and Changing Loans, and Company's Size as determinants of earnings management between Islamic and conventional banks. Also, it was found that Company's Size was the dominant variable determining the management differences. Based on Discriminant Analysis, there were significant differences in the determinants of conventional and Islamic earnings management. The Changing Loan variable showed the highest contribution in determining earnings management in Islamic banks. Overall, this study found that conventional banks dominated Islamic system in practicing earnings management.

This study aims to determine the significant differences in the fair value, equilibrium price, and volatility of LQ45 stock returns before and after the first COVID-19 event. We applied the Multiple Discriminant Analysis test by taking data 75 days before and after the national announcement of the first COVID-19 event for the period 2019-2020. The results showed the significance value of the fair value and the balance price of 0.129> 0.05 and 0.814> 0.05 decreased compared to before the COVID-19 incident. Meanwhile, the value of the volatility of stock returns was 0.047 <0.05. after the announcement shows the value has increased.

  • The effect of macroeconomics and supply chain finance (SCF) on profitability: Evidence from manufacturing companies
    Supriyanto Supriyanto, Mohammad Benny Alexandri, Nenden Kostini, and Ratna Meisa Dai
    Growing Science
    This paper examines the effect of macroeconomics and supply chain finance (SCF) on the profitability of the manufacturing companies, specifically in Indonesia from 2017 to 2021. Furthermore, the study demonstrates the critical role of macroeconomics and SCF in profitability through the use of general moment method (GMM). The results indicate that cash conversion cycle (CCC) is detrimental to profitability (P), while macroeconomics has a positive impact on it. In addition, strong profitability is negatively and positively correlated with the leverage (LEV) and sustainable supply chain management (MRPB) control variables, respectively.

  • Volatility Spillover between Stock Returns and Oil Prices during the Covid-19 Pandemic in ASEAN
    Mohammad Benny Alexandri and Supriyanto Supriyanto
    EconJournals
    This study points to increase global monetary integration as a result of rising volatility spillovers. As a result, analyzing volatility spillovers for international areas that expand and improve through the usage of inventory returns and oil prices is critical. The EGARCH model is used to explore the Volatility Spillovers of oil agencies in five ASEAN international areas during the Covid-19 Pandemic. To assess the interrelationships of the ASEAN stock index as well as the path of volatility, data were acquired from five global sites with very large volatility spillovers, namely Indonesia, Malaysia, Singapore, Thailand, and Vietnam. The findings show that this search is critical for ASEAN traders as well as Filipinos. Furthermore, because accurate forecasting of volatility spillover in global equity markets is required to reduce portfolio risk, this search has a substantial and viable significance.
