Abstract

This study aims to analyze the classification of economic development, development inequality, and the effects of economic growth, the open unemployment rate, and the Human Development Index (HDI) on development inequality in the DIY Province from 2013 to 2019. The approach used in this research is quantitative, utilizing secondary data obtained from Badan Pusat Statistik for the years 2013 to 2019. The method employed to analyze the classification of economic growth is Klassen typology. The Williamson Index is used to analyze development inequality, while panel data regression is applied to examine the factors influencing development inequality. Based on the results of the research on the classification of economic development, it is evident that areas with advanced and fast development are Yogyakarta and Sleman, while fast-developing areas include Kulonprogo, and relatively underdeveloped areas are Gunungkidul and Bantul. The results of the Williamson Index indicate that the largest development inequality exists in the Kulonprogo, Bantul, and Gunungkidul areas, suggesting that there is inequality in community access to development outcomes. Furthermore, the results of the panel data regression show that the economic growth variable has an insignificant negative effect on development inequality, the unemployment variable has a significant positive effect on development inequality, and the HDI variable has a significant negative effect on development inequality in DIY Province. To reduce development inequality in DIY Province, it is necessary to increase employment opportunities based on regional potential and improve human resources to achieve inclusive economic growth.

Abstract

This study aims to determine the impact of non-cash payments on the Rupiah exchange rate through the amount of money circulating in a narrow sense. This research is quantitative, utilizing secondary data as its source. The analytical method used in this study is path analysis, with the dependent variable being the Rupiah exchange rate. The independent variables are the volume of debit card transactions and the volume of electronic money, while the intervening variable is the amount of money circulating in a narrow sense. The period analyzed is from 2017 to 2020. The results show that both the volume of debit card transactions and the volume of electronic money have a significant effect on the Rupiah exchange rate. This study finds in the second model that the volume of debit card transactions, the volume of electronic money, and the Rupiah exchange rate significantly affect the amount of money circulating in a narrow sense.

Abstract

This study aims to analyze the effectiveness of monetary policy transmission implemented by Bank Indonesia through the interest rate and asset price channels in achieving the final target, inflation. The method used in this study is the Vector Error Correction (VEC) model, and the data utilized are monthly data from August 2016 to December 2022. The VEC model shows that, in the long term, the transmission of monetary policy through the interest rate and asset price channels proves to influence inflation. However, in the short term, only the asset price channel shows a significant effect on inflation. The originality of this research lies in analyzing the use of the BI-7 DRR as the new benchmark interest rate in the implementation of the Flexible ITF.

Abstract

This study aims to test the Environmental Kuznets Curve (EKC) hypothesis in ASEAN member countries from 2015 to 2022 and to analyze the effect of per capita GDP, population size, energy transition, foreign investment, and trade openness on carbon emissions in ASEAN member countries from 2015 to 2022. This research uses a quantitative approach with data sourced from the International Energy Agency and the World Bank. The analytical method applied is multiple linear regression using panel data from 10 ASEAN countries for the period 2015-2022. The results show that the Environmental Kuznets Curve (EKC) hypothesis is confirmed in ASEAN member countries for the period 2015-2022, with a turning point for the relationship between per capita GDP and CO2 emissions in the ASEAN region at 17.11 trillion dollars. Singapore and Brunei Darussalam are the two countries among 11 in the ASEAN region that have passed the scale and structural effect phase on the Environmental Kuznets Curve, while others remain on the left side of the EKC. Per capita GDP can significantly increase or reduce carbon emissions in the ASEAN region depending on whether the member country has reached the EKC turning point phase. Population size, foreign investment, and trade openness significantly increase carbon emissions in the ASEAN region. The energy transition can reduce carbon emissions in the ASEAN region, though not significantly.

Abstract

The development of technologies that demand faster and easier operation also encourages the development of payment systems, which is one of the components that can support economic growth. Innovation in the non-cash payment system developed by Bank Indonesia can help people to be able to do transactions easier and faster to fulfill their needs. This study aims to find out the effect of the non-cash payment system using electronic money (e-money) and Card-Using Payment Instruments (APMK) with debit/ATM cards and credit cards on Indonesia's Gross Domestic Product (GDP). The methods used in this study are multiple linear regression analysis with Ordinary Least Square (OLS) models. The type of data used is secondary data in the form of time series in quarterly intervals of the period 2011 to 2021 obtained from the website of Bank Indonesia and Badan Pusat Statistik. The results of the study showed that debit/ATM cards have a significant positive effect on GDP. Meanwhile, credit cards and electronic money do not have a significant effect on GDP. Simultaneously, debit/ATM cards, credit cards, and electronic money have a significant positive effect on GDP, which means that if the use of payments with Card-Using Payment Instruments (APMK) and electronic money (e-money) increases simultaneously, it will encourage an increase in Indonesia's GDP.

Abstract

This study aims to determine the effect of the poverty rate, unemployment rate, and labor force participation rate on the human development index of DKI Jakarta. This study was conducted to find out whether or not those variables are indeed three factors that played an important role in encouraging DKI Jakarta to have the highest human development index among 33 other provinces in Indonesia. This study used panel data from 6 administrative districts and cities in DKI Jakarta during 2010-2021 using a random effect panel regression model. The results showed that there was a significant negative effect of the poverty rate and the open unemployment rate on the human development index. Meanwhile, the labor force participation rate has a significant positive effect on the human development index of DKI Jakarta during 2010-2021. According to the F-statistic, it showed the human development index simultaneously affected by the poverty rate, open unemployment rate, and labor force participation rate within 60% R-squared. This study specifically highlights economics and employment in DKI Jakarta as aspects with the most programs and policies applied.

Abstract

This study aims to analyze the impact of the merger of three dominant-asset Islamic banks on the level of competition in the Islamic banking sector, observed from pre-merger and post-merger conditions, as well as its determining factors. The research uses panel data from 14 banks for the pre-merger condition (2016-2020) and 11 banks for the post-merger condition (2021-2022), applying the Panzar-Rosse Model (H-Stat). The results indicate that the Islamic banking industry in Indonesia exhibits monopolistic market structures in both pre-merger and post-merger conditions. The impact of the merger led to a decrease in the competition level within the industry, as shown by the H-Stat result of 0.949 for the pre-merger condition and 0.910 for the post-merger condition. This study demonstrates that when companies with dominant assets in an industry merge, it results in reduced competition, as the newly formed entity possesses excessive capabilities while other companies are unable to compete effectively.
