Phạm Nhật Tuấn, Lê Vũ Hội, Dương Đăng Khoa
Tóm tắt:
Nghiên cứu này xem xét tác động của hợp đồng phái sinh (HĐPS) và sức mạnh thị trường (SMTT) đến hiệu quả hoạt động (HQHĐ) ngân hàng tại Việt Nam. Nhóm tác giả phân tích mẫu 25 ngân hàng thương mại (NHTM) Việt Nam giai đoạn 2010–2020 bằng mô hình tuyến tính tổng quát. Bài viết phát hiện ra rằng HQHĐ được cải thiện bằng cách sử dụng HĐPS. Hơn nữa, SMTT có tác động tích cực đến HQHĐ khi nó ở dưới mức tối ưu. Ngoài ra, kết quả xác nhận mối quan hệ phi tuyến tính giữa SMTT và HQHĐ ngân hàng. Những kết quả chính này vẫn vững chắc sau khi sử dụng phương pháp bình phương tối thiểu và nhất quán với lý thuyết Đa dạng và SMTT. Cuối cùng, những phát hiện này có giá trị thực tiễn đối với các nhà quản lý ngân hàng và cơ quan hoạch định chính sách trong việc điều hành hệ thống ngân hàng Việt Nam.

Effects of Derivatives and Market Power on Bank Performance: Evidence from Vietnam
Abstract:
This research is a first attempt to investigate how market power and derivatives affect bank performance in Vietnam. We used Generalized Linear Models to examine a sample of 25 Vietnamese commercial banks between 2010 and 2020. Our findings show that utilizing derivatives empowers bank performance in Vietnam. Additionally, we discover that the performance of banks is positively but marginally impacted by market power. Furthermore, the results indicate that market power and bank performance have a non-linear connection. The main findings are robust after employing Robust Least Squares estimations. Our findings are consistent with the market power and diversity theories. Finally, bank managers and policymakers in Vietnam can use our findings to develop sustainable banking performance.
