Beyond Single Opportunity Explanations in International Entrepreneurship Research

This article examines the idea sets framework to better understand the processes and mechanisms in internationalentrepreneurship through a longitudinal study of a serial entrepreneur. I fill in the “opportunity gaps” in internationalentrepreneurship research by introducing the concept of opportunity portfolio processing that involves discovery,creation, prototyping, pruning and broadening of opportunity sets. From here, I offer a set of opportunity portfoliomeasures as new measures of international entrepreneurship performance. In developing these arguments, I presentfive findings that, taken together, move us closer toward a theory of opportunity portfolio in international venturing.
