Abstract

Research Purposes. This study aims to determine the effects of Self-Control, Overconfidence, Herding, and Mental Accounting on Investment Decisions, with Financial Literacy Serving as a moderating variable. Research Methods. The data analysis method used multiple linear regression analysis. Research Results and Findings. The results show that there is a significant effect of self-control and overconfidence on the investment decisions of young investors. Herding has no significant effect on investment decisions due to the tendency of investors to make decisions independently. Mental accounting has no significant effect on investment decisions; good planning in mental accounting does not mean that it will make investors consider every decision taken. The moderating role of financial literacy in self-control, overconfidence, and herding in investment decisions has an insignificant effect. Meanwhile, financial literacy can weaken the negative influence of mental accounting in investment decision-making. The implication of this research is the importance of strengthening self-control and education to control overconfidence in the investment decisions of young investors.

Abstract

Penelitian ini bertujuan untuk menguji pengaruh intensitas emisi karbon terhadap nilai perusahaan serta mengeksplorasi efek moderasi dari kepemilikan institusional. Pengukuran nilai perusahaan menggunakan rasio Tobin’s Q, sementara intensitas emisi karbon diperoleh dari pembagian total emisi Scope 1 dan Scope 2 dengan penjualan perusahaan. Populasi mencakup perusahaan-perusahaan sektor infrastruktur yang tercatat di Bursa Efek Indonesia sepanjang periode 2022–2024. Melalui teknik purposive sampling, diperoleh 93 data observasi. Analisis dilakukan dengan Moderated Regression Analysis (MRA). Hasil penelitian mengungkap bahwa intensitas emisi karbon tidak memberikan dampak signifikan terhadap nilai perusahaan. Kepemilikan institusional pun tidak memoderasi hubungan tersebut. Di sisi lain, kepemilikan institusional, profitabilitas, serta leverage berpengaruh positif terhadap nilai perusahaan, sedangkan ukuran perusahaan tidak menunjukkan pengaruh yang signifikan.

Abstract

On April 2, 2025, President Donald J. Trump imposed a 32% import tariff on Indonesia, triggering significant stock market volatility and global panic. This study aims to provide empirical evidence on whether there are significant differences in aggregate and cumulative abnormal returns before and after Trump’s reciprocal tariff policy announcement. The research adopts an event study approach, using a sample comprising all companies across 11 sectors listed on the Indonesia Stock Exchange. The findings indicate that the Indonesian capital market responded negatively and significantly to Trump’s tariff announcement. This is reflected in a significant decline in the Aggregate Abnormal Return (AAR) on the first day following the announcement. The decline is also evident in the Cumulative Aggregate Abnormal Return (CAAR), which illustrates the aggregate market losses accumulated during the event window. However, the drop in AAR and CAAR lasted only for two days post-announcement, after which signs of recovery emerged from the third to the fifth day. Further analysis of sectoral Abnormal Returns (AR) shows that most sectors closely linked to international trade activities experienced a significantly negative decline in AR.
