Abstract

Koperasi adalah lembaga bisnis yang berwatak sosial. Sebagai institusi bisnis, koperasi mau tak mau menghadapi kompetisi bisnis yang kian ketat. Apapun jenisnya, koperasi terus menghadapi persaingan usaha baik terhadap koperasi sejenis (produksi dan pemasaran), persaingan dengan lembaga pembiayaan non bank/perbankan bagi KSP, koperasi kredit atau koperasi yang memiliki unit simpan pinjam (USP), dan persaingan dengan ritel modern bagi Koperasi Serba Usaha (KSU), koperasi wanita, koperasi fungsional, dan koperasi masyarakat. Namun yang paling merasakan sengitnya persaingan usaha adalah koperasi yang tumbuh di masyarakat seperti KSP, kopdit, kopwan, KSU, dll. Penelitian yang telah dilakukan di Pondok Pesantren di kawasan kabupaten Blitar. Tentang Usahausaha mengembangkan koperasi selaras dengan zaman, agar semakin kompetitif. Model penelitian secara deskriptif kualitatif menjadi desain untuk melihat dari dekat tentang kebijakan dan usaha yang dilakukan oleh koperasi Hasil penelitian yang diperoleh menunjukkan yaitu; (1). Penggunaan IT untuk meningkatkan pelayanan kepada anggota koperasi. (2). Melaksanakan manajemen yang memiliki transparansi dan akuntabilitas untuk meningkatkan kepercayaan anggota kepada pengelola koperasi. (3). Menyelenggarakan pendidikan dan pelatihan (diklat) secara berkelanjutan. (4). Mengikutsertakan pengurus dan pengelola koperasi pada acara temu ilmiah yang relevan, dan belajar mandiri untuk meningkatkan kompetensi mereka dalam mengelola koperasi yang semakin modern.

Abstract

This study investigates a wandering weekday effect, an assumption anomaly from fixed weekday effect to changes over time, under the moderation effect of market trend. We employ daily price data from the Jakarta Stock Exchange (JKSE) from 2000 to 2019. This study reveals that the fixed weekday effect has diminished when we introduced a market trend. Using robustness of distribution error, our further studies find that there is a negative wandering Monday effect when the market is falling. The findings provide a crucial contribution to market efficiency and help to reconcile mixed findings in previous studies

Abstract

The study investigates how systematic, continuous, and discrete (jump) risk can explain the equity returns in Southeast Asia markets. Using the latest econometric techniques and a high-frequency dataset, I construct two high-frequency betas associated with intraday continuous and discontinuous risk premia. To improve our consistency, I employ several statistical robustness levels and multiple frequencies. The findings show that both continuous and discontinuous risk premia are significant and positive in Indonesia, and these results are consistent for lower frequency data samples. Furthermore, the study reveals that diffusive and jump risk premia have different impacts in other countries, but the results are not consistent for lower frequency samples.

Abstract

The study investigates how systematic, continuous, and discrete (jump) risk can explain the equity returns in Southeast Asia markets. Using the latest econometric techniques and a high-frequency dataset, I construct two high-frequency betas associated with intraday continuous and discontinuous risk premia. To improve consistency, I employ several statistical robustness levels and multiple frequencies (one minutes, five minutes, ten minutes, and thirty minutes). The findings show that both continuous and discontinuous risk premia are significant and positive in Indonesia, and these results are consistent for lower frequency data samples. Furthermore, the study reveals that diffusive and jump risk premia have different impacts in other countries, but the results are not consistent for lower frequency samples.

Abstract

This research studies the trading activity of type of traders through their brokers. Order imbalance is believed to be a better proxy for explaining trading activity. This paper presents some empirical test that on brokerage level analysis exhibit information paradigm in Indonesia which market makers and specialist are not available. We divide imbalances into groups of samples (all stocks and most liquid stocks), trader type (foreign or domestic) and size of brokerage firm (small to big). Our results show that order imbalances generally have a positive serial correlation for all the traders and brokers analyzed. However, we find that the determinant of order imbalances is a particular phenomenon at the brokerage level, whose results differ from our market-wide analysis. We do not find that previous order imbalances can predict market returns across trader type and brokerage class. In contrast, for the inventory paradigm, the evidence from the brokerage level analysis indicates that information dissemination is induced order imbalance by brokerage house.

Abstract

We investigate the systemically important banks in the Indonesian financial system usingMultivariate GARCH Conditional Value at Risk (CoVaR). The systemic risk measurement, ΔCoVaR,defined as the change from CoVaR in its benchmark state as a one-standard-deviation event to itsCoVaR under financial distress. We estimate the systemic risk contribution using 21 commercialbanks from January 2007 to December 2018. Our study reveals that the top five ranking systemicbanks are dominated by state-owned banks, and its ranking is consistently the same in the periodbefore, during, and after the global financial crisis. Finally, we empirically find that systemic riskin Indonesia is strongly affected by external factors rather than bank characteristics. Based on this finding, we suggest that the government should maintain the regulation of external effect rather than the domestic effect.
