Abstract

This study is motivated by the importance of macroeconomic variables in stock market investments, such as interest rates, inflation, and exchange rates. The Composite Stock Price Index (IHSG) is often used as an indicator of Indonesia's capital market development, providing a general market overview. IHSG movements are significantly influenced by macroeconomic conditions, making it essential to analyze these variables to minimize investment risks. This research employs a quantitative approach with an associative type of study. Data were collected from the official websites of the Indonesia Stock Exchange and Bank Indonesia using purposive sampling, with a total of 60 samples. The analysis utilizes time series data and includes tests such as unit root test, optimum lag, stability, Granger causality, cointegration, VECM, IRF, and VD, processed with E-Views 9 software. The results show: 1) A unidirectional causality relationship exists between IHSG and the BI 7-Day Repo Rate; 2) A unidirectional causality relationship exists between IHSG and inflation; 3) A bidirectional relationship exists between the exchange rate and IHSG.

Abstract

The phenomenon of K-Pop idols from South Korea, known as Hallyu or the Korean Wave, has widely spread to Indonesia. This culture is highly favored by the community, especially Generation Z, who actively follow trends, including the consumption of K-Pop merchandise. This study aims to examine the influence of financial literacy, self-control, and consumer behavior on K-Pop merchandise consumption among Generation Z students at UIN Sayyid Ali Rahmatullah Tulungagung. The research method used is quantitative, with questionnaires distributed via Google Forms to 116 respondents. The data were analyzed using SPSS 29 through validity tests, reliability tests, classical assumption tests, and multiple linear regression. The results indicate that financial literacy has a significant effect on K-Pop merchandise consumption, while self-control and consumer behavior have a positive but not statistically significant partial effect. Simultaneously, these three variables have a significant influence on merchandise consumption.
