This paper analyzes the macroprudential policy by the central bank to maintain the financial system stability. Using panel data of the government banks, foreign, private, joint venture, and regional development banks during 2004- 2012, we employ Vector Autoregressive Exogenous (VARX) and event analysis method and find that the level of exchange rate volatility decrease after the implementation of the one month holding period, six-month holding period and net open position policies. However, for the nominal exchange rate, these policies are not effective. In aggregate the reserve requirement plus loan to deposit ratio policy is effective to raise the bank credit allocation. Furthermore, the impact of the primary reserve policy is very limited to lower the liquidity of the economy; while at the same time the flow of foreign capital comes into very heavy

The fluctuating development of chili prices implies that the maintained supply of chili is very important to maintaining the stability of food prices. The value chain integration of the chili commodity from upstream to downstream supported by the availability of adequate infrastructure and institutions is the main prerequisite in increasing the productivity of chili commodities. The purpose of this study is (1) to give a description of the chili commodity marketing chain in Banyuwangi Regency; (2) analyze the determinants of structure, conduct, and performance of the chili commodity market in Banyuwangi Regency. The analytical method used consists of the Autoregressive Integrative Moving Average (ARIMA) and Structure Conduct Performance (SCP) models.The results of the study show that price determination was based on market mechanisms and collective agreements for farmers who partner with collectors and food processing industries. However, the lack of price and knowledge information in market analysis and projections of price movements and the absence of special institutions that deal with chili governance and limited use of technology have led to the emergence of asymmetrical information from chili businesses and the growth of new players in the trade system that dominates the chili trade. The chili market structure tends to oligopsony, which has the power to influence market prices and is concentrated, causing little competition between chili traders in Banyuwangi Regency.

Investasi portofolio merupakan jenis investasi yang rentan terhadap guncangan baik yang bersumber dari dalam maupun luar negeri. Tujuan dari studi ini adalah untuk mengetahui pengaruh guncangan variabel inflasi, suku bunga dan nilai tukar riil efektif terhadap aliran investasi portofolio di empat negara ASEAN pada periode 2001Q1–2018Q4. Hasil analisis dengan menggunakan metode Structural Vector Autoregressive (SVAR) menunjukkan bahwa suku bunga merupakan determinasi utama investasi portofolio di Singapura dan Filipina. Sedangkan inflasi dan nilai tukar menjadi determinasi utama investasi portofolio di Indonesia dan Malaysia. Studi ini merekomendasikan bahwa kebijakan pengelolaan arus modal dalam bentuk investasi portofolio sebaiknya mempertimbangkan variabel makroekonomi tersebut, mengingat besarnya potensi risiko yang dapat ditimbulkan terhadap stabilitas perekonomian terutama dalam jangka pendek.

Digitalization has an essential role during the pandemic because it helps facilitate various economic activities. This study aims to analyze the economic digitization of financial technology on economic growth in the Sumatra region (North Sumatra, West Sumatra, and South Sumatra) in January 2020-June 2021. We also used macroeconomic indicators in the form of inflation, foreign direct investment (FDI), and domestic investment (DI) as a control to explain economic conditions. The analysis results using the Panel Vector Autoregression (P-VAR) showed that fintech contributed positively to economic growth. This result was supported by maintained inflation stability that created a conducive investment climate, thereby attracting FDI. We recommend that the regional government take advantage of existing fintech and that "prudent" policies on inflation management must always be adequately prioritized to support the acceleration of economic growth in the Sumatra region, especially North Sumatra, West Sumatra, and South Sumatra.
