Abstract

This study examines the challenges in implementing contract theory, particularly related to corporate performance pay as a solution to promotion risk in a competitive environment. Performance-based pay serves to increase employee motivation and reduce uncertainty in promotion, but has the potential to create unhealthy competition and reduce teamwork. This study suggests that a balanced incentive contract design, which combines financial and non-financial rewards, can optimize individual performance without sacrificing team harmony. Although performance-based pay can provide short-term benefits, it is important for companies to consider its long-term impact on employee satisfaction and collaboration within the organization. This study provides theoretical and practical insights for companies in designing fair and effective promotion systems

Abstract

Penelitian ini melakukan tinjauan literatur kualitatif mengenai hubungan antara manajemen risiko, struktur modal, dan penggunaan derivatif dalam meningkatkan efisiensi pembiayaan. Analisis ini mensintesis bukti empiris terbaru tentang bagaimana instrumen derivatif, khususnya derivatif cuaca dan valuta asing, mengurangi eksposur risiko serta memengaruhi ketentuan kontrak utang, biaya modal, dan nilai perusahaan. Temuan menunjukkan bahwa strategi lindung nilai tidak hanya menurunkan biaya pembiayaan tetapi juga memperkuat kemampuan perusahaan untuk mempertahankan fleksibilitas keuangan di tengah ketidakpastian iklim dan pasar. Selain itu, tata kelola perusahaan dan praktik pengungkapan memainkan peran moderasi dalam menentukan efektivitas penggunaan derivatif dalam mengelola risiko dan mengurangi asimetri informasi. Tinjauan ini menyoroti perspektif terpadu di mana manajemen risiko menjadi determinan strategis dalam pengambilan keputusan struktur modal dalam konteks keuangan dan lingkungan yang dinamis

Abstract

Kajian literatur kualitatif ini mengeksplorasi bagaimana akuntansi berfungsi sebagai infrastruktur dasar informasi risiko dalam model faktor harga aset. Dengan merujuk pada studi terkini dalam akuntansi keuangan dan penetapan harga aset, sintesis ini menyoroti bagaimana prinsip-prinsip akuntansi—seperti pengukuran berbasis akrual, konservatisme, dan pengakuan aset takberwujud—membantu menjelaskan variasi silang dalam imbal hasil saham. Kajian ini membahas bagaimana laporan keuangan menyumbang pada berita arus kas (cash-flow news) maupun berita tingkat diskonto (discount-rate news), sehingga memperkuat peran akuntansi dalam membentuk ekspektasi pasar. Selain itu, variabel-variabel berbasis akuntansi terbukti dapat melengkapi atau bahkan menggantikan faktor risiko tradisional seperti dalam model Fama-French. Temuan ini menyiratkan bahwa integrasi informasi akuntansi ke dalam kerangka penetapan harga aset meningkatkan estimasi risiko, akurasi valuasi, dan kekuatan prediktif, khususnya dalam perekonomian yang semakin digerakkan oleh modal takberwujud

Abstract

This qualitative literature review explores the strategic role of non-venture private equity (PE) firms as intermediaries in corporate asset markets. Distinct from venture capitalists, these PE firms specialize in acquiring, restructuring, and reallocating mature corporate assets, thereby enhancing market efficiency and value creation. By synthesizing recent studies, this review highlights how non-venture PE firms facilitate resource redeployment, drive operational improvements, and influence corporate governance. Comparative analysis reveals their unique ability to exploit inefficiencies through carve-outs, platform building, and targeted acquisitions. The review also examines emerging ESG considerations and critiques regarding short-termism and stakeholder impact. While the literature acknowledges the transformative role of these firms, it also identifies limitations in theoretical integration and empirical coverage. This study contributes to a deeper understanding of how non-venture PE firms shape firm boundaries, market structures, and the evolving logic of strategic intermediation.
