Ổn định ngân hàng, Cạnh tranh ngân hàng, Bất định chính sách kinh tế

Tóm tắt

Nghiên cứu này kiểm tra vai trò điều tiết của bất định chính sách kinh tế đến mối quan hệ giữa cạnh tranh và ổn định ngân hàng tại 20 quốc gia qua giai đoạn từ năm 2009 đến năm 2023. Bằng cách sử dụng mô hình biến công cụ thông qua phương pháp mô men tổng quát (Generalized Method Of Moments ‒ GMM) dựa trên dữ liệu không cân bằng ở cấp độ ngân hàng, kết quả nghiên cứu ủng hộ giả thuyết cạnh tranh - ổn định và đồng thời khẳng định tác động điều tiết của bất định chính sách kinh tế đến mối quan hệ giữa cạnh tranh và ổn định ngân hàng, thông qua chỉ số bất định chính sách kinh tế (Economic Policy Uncertainty – EPU). Điều này được củng cố vững chắc thông qua phương pháp ước lượng bình phương bé nhất khả thi (Feasible Generalized Least Squares - FGLS), ước lượng bình phương bé nhất vững (Robust Ordinary Least Squares) và hồi quy sai số chuẩn Driscoll-Kraay. Tuy nhiên, tất cả đều không tìm thấy kết quả tương tự với bất định chính sách kinh tế được đo lường thông qua chỉ số bất định toàn cầu. Nghiên cứu thực nghiệm của tác giả có ý nghĩa chính sách cụ thể đối với nhà quản trị ngân hàng, nhà hoạch định chính sách trong việc ra quyết định nhằm nâng cao sức cạnh tranh, ổn định hệ thống ngân hàng trong bối cảnh bất định chính sách kinh tế hiện nay.
