The 4th edition of the International Conference on Quantitative and Qualitative Methods for Economics, Management, and Social Sciences (QQR’22) is a major event for researchers and practitioners to share ideas in the fields of Quantitative and Qualitative approaches, Economics, Finance, Management, and Social Sciences from both theoretical and practical perspectives. We strongly encourage contributions that describe real-world problems, interdisciplinary research, experimental and/or theoretical studies, while providing new insights into the areas of Quantitative and Qualitative Methods.
