Contemporary social science in general and economics in particular are dominated by the method of logical positivism in the British tradition. In contrast to the British philosophy, Subjectivism and Interpretative Methodology in Theory and Practice adopts subjectivism and interpretation methodology to understand human behavior and social action. Unlike positivism, this subjectivist approach, with its root in German idealism, takes human experience as the sole foundation of factual knowledge. All objective facts have to be interpreted and evaluated by human minds. In this approach, experience, knowledge, expectation, plans, errors and revision of plans are key elements. Specifically, this volume uses the subjectivist approach originated in Max Weber’s interpretation method, Alfred Schutz’s phenomenology, and Peter Berger and Thomas Luckmann’s sociology of knowledge to understand economic and social phenomena. The method brings human agency back into the forefront of analysis, adding new insights not only in economics and management, but also in sociology, politics, psychology and organizational behavior.
