Human behavior and judgment: A critical nano-foundation for the Uppsala model and international business studies

Economists and researchers of decision-making and business behavior increasingly rely on findings from the field of economic psychology. We argue that, by following a similar route, knowledge of firms’ internationalization is considerably enriched. The aim of this commentary is to point to the potential of including insights from research on human cognition and judgment in explaining internationalization behavior. We offer some examples relying upon commitments and knowledge development as outlined in the Uppsala model and thereby propose a conceptualization linking the nano- and micro-levels within the model.
