The aim of this summer school is to discuss the strength and weaknesses of both research pillars and their contribution to our understanding of how boards are formed and how they work in order to effectively perform their roles. We explicitly aim to determine to what extent their questions, methods, data, and outcomes are complementary or substitutes. Our approach is multi-disciplinary, meaning that we discuss research from economics, finance, management and sociology and psychology. We will also deal with measurement issues and discuss datasets and methodologies to use these datasets in research. Participants are invited to present their own research (ideas) in the field of board effectiveness.
